Opis:

W artykule opisano sposób pomiaru nowej cechy tekstyliów jaką jest rezystancja punktu styku i linii styku dwóch nitek elektroprzewodzących nazwana łącznie rezystancją przejścia. Cecha ta ma kluczowe znaczenie w systemach tekstronicznych łączących technologie włókiennicze z elektronicznymi i informatycznymi. Podano przykładowe wyniki pomiarów przeprowadzonych na unikatowych stanowiskach pomiarowych. Opisano też weryfikację hipotezy o wpływie długości linii styku na wartość rezystancji przejścia.
The paper describes a method for measuring the new feature of textiles, namely the resistance of a contact point and contact line of two electro conductive threads. It is known as a transition resistance. The feature is of special importance in case of textronic systems combining textile, electronic and informatic technologies. The scheme of electroconductive woven fabric and its electrical model is shown. In the structure the contact point resistance is dominant. The contact line resistance is characteristic for knitted structures. They are presented, too, and their electrical model is described. The analysis of the influence of a lap angle of two electro conductive threads on the contact line length was performed. There are also given some results of measurements taken on unique measuring stands. Verification of the hypothesis concerning the influence of the contact line length on the transition resistance value is described. The hypothesis says that when the contact line length increases the line resistance decreases in the lap angle range from 20° to 120°. For the angle value higher than 120° the phenomenon does not exist. The analysis of this phenomenon will be the subject of next investigations.

Opis:

Evolving threats to national security have resulted in the adoption of comprehensive (total) defence concepts by a number of small and medium states. Civil resistance constitutes a considerable part of such concepts, complementing military defence. The historical experience of Lithuania proved the value of nonviolent resistance between 1988 and 1991 for regaining independence, and defending it in January 1991. The aim of this article is to analyse the role of non-violent civil resistance in the national defence system, based on the experience of 13 January 1991 in Lithuania and develop further discussion about the concept of civil resistance. The methodological approach of the article is based on historical and theoretical analysis. This allows the experience of Lithuania to be assessed on the basis of Lithuanian National Security and Defence Strategy and scientific research. Lithuanian non-violent civil resistance in 1988–1991 was successful in terms of strategy, leadership, organisation, planning, non-violence priorities and the number of citizens involved. The leaders of the movement were able to mobilise people into a widespread movement based on their moral authority and value orientations, strongly appealing to different groups in society. Lithuania’s independence was achieved with minimal human sacrifice, preserving the country’s resources and infrastructure. This experience of non-violent civil resistance came to be used by modern state institutions to create strategic documents of the state. In the current situation, it is necessary to focus not only on the knowledge required for state defence and civil resistance, but also on its moral aspects such as values, ethical behaviour, civic and human maturity.

Opis:

Zinc is an essential element for all living organisms, but overexposure to this element can have strongly toxic effects. A pot experiment was carried out to evaluate the influence of different zinc concentrations (0, 100, 300, 600, 1200, 2400, 4800 mg Zn2+ kg-1 of soil) on the soil biological activity by analyzing changes in soil stability over time and by determining the resistance (RS) of microorganisms and soil enzyme activity. The influence of Zn2+ on the growth and development of oat and white mustard was evaluated. Overexposure to zinc inhibited the growth of soil microorganisms, the activity of soil enzymes, and the growth and development of plants. Excessive zinc doses cause lower microbial biodiversity and enzyme activity. Bacteria of the genus Azotobacter were most sensitive and spore-forming oligotrophic bacteria were least sensitive to excessive zinc doses. β-glucosidase was most resistant and arylsulfatase was least resistant to the analyzed element. The resistance of the tested microorganisms and enzymes decreased with an increase in zinc accumulation in the soil environment. White mustard was more sensitive to zinc contamination than oat and zinc doses of 2400 and 4800 mg Zn2+ kg-1 led to the death of white mustard plants. The results of this study indicate that soil contamination with zinc poses a threat for living organisms. In areas with a higher risk of zinc deposition, the content of this element in soils should be monitored more frequently than prescribed by environmental protection regulations.

Sintered ferrous components were coated with electrochemical chromium coatings modified with nanodiamond particles. The nanodiamond particles were produced by detonation synthesis with an average grain size 8 nm. The objective of this study was to determine the tribological properties and the corrosion resistance of sintered iron samples coated with an electrochemically deposited chromium layer modified with nanodiamond particles. The thickness of the obtained composite coatings was more than 25 μm. The microstructure and microhardness were determined by metallographic methods. The mechanical and chemical properties of the samples were compared to uncoated samples prepared from the same iron powder. The microhardness was 5 times higher, the wear resistance increased 6 times and the corrosion resistance in 0.1 M NaCl solution was 10 times higher.

The tests were carried out on the innovative laboratory stand for tribological tests using the method for determination of resistance to edge fracture and abrasive wear. Test results have shown that an increase in the size of tungsten carbide grains, and thus an increase in the cobalt content, reduces the wear resistance and increases the resistance to brittle fracture. The results of the tests of sintered carbides inserts in the aspect of their durability are presented.

Opis:

This work aims at physico-mechanical properties of the Ti-containing chromium-free conversion coatings on zinc coated steel. The wear resistance of the whole conversion coating/zinc coating system depends on the deposition time of these coatings. As the duration of the deposition of conversion coatings containing titanium increases, the wear resistance of the samples decreases. The reason for this deterioration in wear resistance is likely worse adhesion of these coatings obtained at longer deposition times. The best adhesion to the zinc substrate posses coatings deposited for 20 s.

Opis:

An excessive use of antimicrobial agents poses a risk for the selection of resistant bacteria. Of particular interest are antibiotics that have large consumption rates in both veterinary and human medicine, such as the tetracyclines and macrolidelincosamide-streptogramin (MLS) group of antibiotics. A high load of these agents increases the risk of transmission of resistant bacteria and/or resistance determinants to humans, leading to a subsequent therapeutic failure. An increasing incidence of bacteria resistant to both tetracyclines and MLS antibiotics has been recently observed. This review summarizes the current knowledge on different tetracycline and MLS resistance genes that can be linked together on transposable elements.

Opis:

The article presents an electrical model of a resistance furnace with two electrodes encompassing the generation of Joule heat. The characteristic feature of this model was the consideration of contact resistance between the electrodes and the slag. A series of analyses were conducted based on this model. Firstly, the impact of contact resistance on current flow and Joule heat generation in the furnace was assessed, demonstrating its significant importance. A separate group of analyses focused on the spatial configuration of the furnace and its interaction with the aforementioned phenomena. The impact of symmetric and asymmetric electrodes immersion was analysed. In addition to the impact on current flow, the study also demonstrated the influence on the natural convection mechanism described by the proposed measures of the spatial non-uniformity of heat generation. The research showed that symmetric electrode immersion allows for the generation of more heat in the system at a constant voltage. Asymmetric electrodes immersion causes an increase in the non-uniformity of heat generation, which translates into a higher intensity of natural convection.

The Czech winter wheat cv. Regina which does not possess specific genes for powdery mildew resistance except Pm5 was crossed with the cvs. Florida, Tjelvar, Agra, Olymp and Sabina, all possessing T1BL-1RS and the dominant suppressor SuPm8, with Riebesel 47/51 possessing substitution 1R-1B and SuPm8 and with the T1BL-1RS cvs. Sparta, Iris, Mona without SuPm8. Powdery mildew isolates avirulent on Pm8 and virulent on other Pm genes were used in the trials. Tests for resistance were carried out either on seedlings at the first leaf stage or on detached leaves cultured on benzimidazolagar. No segregation for resistant plants in F₂ of all crosses of the cv. Regina with cultivars possessing T1BL-1RS and SuPm8 indicates that Regina has SuPm8. The segregation ratio 3 resistant: 13 susceptible in the F₂ population of crosses between the cv. Regina and cultivars possessing T1BL-1RS and no SuPm8 also confirms the presence of SuPm8 in the cv. Regina. The obtained results also indicate that expression of Pm2 and Pm4b is not affected by SuPm8 and that SuPm8 does not affect stem rust resistance gene Sr31 located on 1RS segment.

Opis:

Currently, we are facing the ever-increasing phenomenon of bacteria being resistant to antibiotics. It is the consequence of excessive and incorrect use of drugs. The phenomenon is a global problem affecting bacteria both in their hospital population and in the natural environment. Municipal waste is an environment conducive to the development of microorganisms, therefore it contains various groups of bacteria, including drug-resistant staphylococci. The aim of the study was to identify species of bacteria, determine their antibiotic resistance, and assess the occurrence of genes responsible for methicillin resistance in Staphylococcus aureus isolated from mixed municipal waste. Strains were isolated by Koch’s serial dilution method with the use of microbiological media. Species were identified using the MALDI TOF-MS technique, whereas the drug resistance profile was determined by disk diffusion and molecular PCR methods. 250 isolates of S. aureus were collected. The highest resistance found was to cefoxitin, erythromycin and tetracycline. Among the bacteria collected, resistance to 1, 2, 3 or 4 antibiotics at the same time was the most common, with a maximum of 10. Additionally, 45 (18%) MDR (multidrug-resistant) isolates were detected. Methicillin resistance was found by the disk diffusion test in 60 (24%) strains, while the mecA gene was detected in as many as 180 (72%) isolates.

Phytophthora infestans behaves in natural and agricultural ecosystems as a biotrophic pathogen, although it can be cultured on artificial media. Pathogenicity and host adaptation are therefore essential traits to understand its biology and to come up with durable, efficient management of late blight. The present review focuses on adaptation to host species and host cultivars, and to both qualitative and quantitative types of resistance. It also discusses some of the patterns and population mechanisms involved in this adaptation, such as selection, genetic drift and migration. This highlights the need for an in-depth analysis of each local situation to accurately describe and understand the mechanisms responsible for observed population displacements.

The paper presents the results of studies of hybrid composite layers Ni/Al₂O₃/C_graphite produced by the electrodeposition method. Three variants of hybrid composite layers were prepared in electrolyte solutions with the same amounts of each dispersion phases which were equal to 0.25; 0.50 and 0.75 g/dm³. The structure of Ni/Al₂O₃/C_graphite layers as well as the Al₂O₃ and graphite powders, which were used as dispersion phases was investigated. The results of morphology and surface topography of produced layers are presented. The modulus of elasticity and microhardness of the material of produced layers were determined by DSI method. Tribological and corrosion resistance tests of produced layers were carried out. Realized studies have shown that the material of the produced layers is characterized by a nanocrystalline structure. Incorporation of dispersion phases into the nickiel matrix increases the degree of surface development of layers. Ni/Al₂O₃/C_graphite layers are characterized by high hardness and abrasion resistance by friction, furthermore, they provide good corrosion protection for the substrate material.

Opis:

The aim of the paper was studying the resistance during splicing of soil, represented by the horizontal resistance component (Fx), depending on changes of speed and working depth of a work piece in form of a duckfoot share. The study was realized under laboratory conditions in a soil channel which ensured repeatability of results. The tested work piece was a duckfoot share with width of 135 mm installed on a spring tine type VCO with stiffness of 8.3 kNm-1. The tests utilized two working depths for the tool: 0.03 and 0.05 m and two working speeds: 0.84 and 1.67 ms-1. Changes in the horizontal resistance component (Fx) depended on the speed and the working depth. At constant parameters of the soil and the tool, change in working depth from 0.03 to 0.05 m resulted in increase of resistance by 42.6% for the working speed v1 = 0.84 ms-1 and 58.8% for v2 = 1.67 ms-1.
Celem pracy było zbadanie oporu skrawania gleby, reprezentowanego przez poziomą składową oporów (Fx), w zależności od zmian prędkości i głębokości roboczej dla elementu roboczego w postaci gęsiostopki. Badania przeprowadzono w warunkach laboratoryjnych w kanale glebowym zapewniającym powtarzalność wyników. Badanym elementem roboczym była gęsiostopka o szerokości konstrukcyjnej 135 mm zamocowana na zębie sprężystym typu VCO o sztywności 8,3 kNm-1. W badaniach stosowano dwie głębokości robocze narzędzia: 0,03 i 0,05 m, oraz dwie prędkości robocze: 0,84 i 1,67 m-s-1. Zmiany wartości składowej poziomej oporów (Fx) zależały od prędkości i głębokości roboczej. Dla stałych parametrów gleby i narzędzia, zmiana głębokości roboczej z 0,03 do 0,05 m spowodowała przyrost oporów o 42,6% dla prędkości roboczej vi = 0,84 ms-1 i 58,8% dla v2 = 1,67 m-s-1.

Opis:

Narodowa Demokracja proclaimed its programme to resign from violence as a military activity and manifested its reluctance to insurrectionary techniques of political fighting. It postponed the decision to begin a national uprising, which was supported by a number of factors. Narodowa Demokracja were willing to benefit from the impact made by social authority figures like the Church, the school, and the press. The rules they set out condemned any political loyalty to the occupants. They encouraged passive resistance against Russification or Germanisation and engagement in legal political activities. Narodowa Demokracja focused on how to organise effectively education and upbringing with the use of available means to educate the Polish nation. The experience of the partitions was disregarded when Sanacja, a Polish coalition political movement, was in power. As a result, a wide range of nonviolent resistance methods was adopted, including political and economic boycott.

Opis:

W artykule poruszam zagadnienie pułapek pojawiających się w pracy z kategorią oporu i jej zastosowaniem w analizach teoretycznych oraz empirycznych. Prezentuję różne ujęcia tego pojęcia oraz omawiam jego wieloaspektowość i kontekstowość. W ramach pracy z tą kategorią wyłoniła się problematyka jej polaryzacji. Zjawisko to z jednej strony powoduje rozmycie kategorii oporu, z drugiej zaś może przyczynić się do jej nadmiernego zawężenia. Zarówno w jednym, jak i w drugim przypadku pojawia się ryzyko dostrzegania oporu w każdej sytuacji lub ignorowania jego wyraźnych przejawów. Celem tekstu jest ukazanie trudności w pracy ze złożoną kategorią teoretyczną i empiryczną, jaką niewątpliwie jest „opór” oraz omówienie pułapek wynikających z braku wnikliwej analizy literatury a także krytycznej refleksji nad studiami teoretycznymi i praktycznymi dotyczącymi danego pojęcia i terminów z nim związanych.
The article addresses the issue of pitfalls which appear during work with the category of resistance and its application in theoretical and empirical analyses. The article presents different perspectives on this notion and discusses its multidimensional character and contextuality. What emerged from the work with that category is its polarization. This phenomenon blurs the category of resistance, at the same time contributing to its excessive limitation. In both cases, there is a risk of recognizing resistance in every situation or ignoring its explicit displays. The aim of the article is to show the struggles of working with a complex theoretical and empirical category that is “resistance” as well as to discuss the pitfalls resulting from the lack of athorough literature analysis and a critical reflection on theoretical and practical studies concerning a given concept and terms connected to it.

Opis:

In the present paper presented are the results of prediction of total resistance of inland waterway vessels based on model test data. In scaling the resistance from model to full scale the extrapolation with two-dimensional frictional resistance formulation (without form factor) was applied, combined with different methods of determination of frictional (viscous) resistance coefficient. There were used the equations that include the effect of water depth, with and without account for pressure gradient. It was shown that limited depth of water substantially affects the frictional resistance. The results of example calculations are compared to resistance prediction made using the ITTC 1957 modelship correlation line. Example calculations take into account the limited depth of water. Depending on the applied method of determination of frictional resistance coefficient the resultant total resistance of inland waterway vessel is higher or lower than the resistance based on the ITTC 1957 correlation line. The effect of water depth depends on the ratio of water depth to ship draught (h/T), on ship speed, and on the composition of a convoy. The extrapolation of resistance was made without including the form factor. Computations are made based on model test data for an inland waterway cargo vessel, for a kombi-type convoy of an inland waterway cargo vessel and a dumb barge, and for a convoy of two dumb barges without a pushboat.

Opis:

The effect of mechanical treatment of beech wood surface on quality of surface finish. The paper deals with the quality of three surface finishes intended into interior. Three types of coating materials were tested (polyurethane, waterborne, wax). Each type of the surface finish was created on beech wood surface in three various coating thicknesses. The coating thicknesses differed in number of coatings of the coating material. The surface finishes were evaluated according to the impact resistance and the resistance to abrasion. The polyurethane surface finish showed the lowest resistance to abrasion. If the film thickness was increasing, the resistance to abrasion was decreasing. The greatest differences in the resistance to abrasion, depending on the wood surface treatment, were found on the wax surface finish. In general, the waterborne surface finish showed the best resistance to abrasion. Pressing the wood surface before finishing increased the impact resistance of all three surface finishes. The damage of the surfaces was only of grade 2 (No cracks on the surface and the intrusion was only slightly visible). The lowest impact resistance of the surface finishes was found on grinded wood surface; the damage was graded as 4 (Visible large cracks at the intrusion). At the drop height of 400 mm, the effect of the film thickness on the impact resistance was no longer present on all differently mechanically treated surfaces.
Wpływ obróbki mechanicznej na jakość wykończenia powierzchni drewna bukowego. Artykuł dotyczy oceny jakości trzech wykończeń powierzchni przeznaczonych do użytku wnętrznego. Zbadano trzy rodzaje powłok wytworzonych na drewniw bukowym na bazie: lakieru poliuretanowego, lakieru wodnego i wosku. W każdym z przypadków wytworzono powłoki w trzech różnych grubościach (zróżnicowanych liczbą krotności naniesienia materiału powłokowego). Jakość powierzchni oceniano w oparciu o pomiar odporności na uderzenia i odporności na ścieranie. Powłoki wytworzone na bazie lakieru poliuretanowego charakteryzowały się najniższą odpornością na ścieranie. Wzrost grubości powłoki wpływał na spadek odporności na ścieranie. Największe różnice w odporności na ścieranie, w zależności od obróbki powierzchni drewna, stwierdzono dla powłok wytworzonych na bazie wosku. Ogólnie stwierdzono, że powierzchnie wykończone powłokami na bazie lakierów wodnych charakteryzowały się najlepszą odpornością na ścieranie. Zagęszczenie powierzchni drewna przed wykończeniem zwiększyło odporność na uderzenia dla wszystkich rodzajów wykończeń powierzchni. Odnotowano jedynie 2 stopień uszkodzenia powierzchni (brak pęknięć na powierzchni i ślad po kuli tylko nieznacznie widoczny). Najniższą odporność na uderzenia odnotowano dla próbek drewna o szlifowanej powierzchni; odnotowano 4 stopień uszkodzenia (widoczne duże pęknięcia przy wgłębieniu). Dla wysokości rzutu 400 mm, bez wzgledu na sposób obróbki powierzchni drewna, nie odnotowano wpływu grubości powłok na udarność.

The aim of this study was to examine the contribution of the sense of self-dignity in accounting for the variability of psychological well-being in women with insulin resistance. The sample consisted of 109 women diagnosed with insulin resistance. The associations between the variables were examined using correlation and regression analyses. The study found significant relationships between dimensions of the sense of self-dignity and psychological well-being in the surveyed women. The loss dimension of the sense of self-dignity had the highest contribution in accounting for all the dimensions of psychological well-being. Although weaker than for the loss dimension, a statistically significant contribution was also found for the total score of the sense of self-dignity in the surveyed women with insulin resistance.

The article presents regression formulas for calculating the friction resistance RF and the total resistance RT of ship models in the 2.0–10.0 m range. The method for calculating the total resistance is novel and applies to the design models of an unmanned surface vessel (USV) for experimental testing of autonomous control. For both regression models (RF and RT), statistical and substantive tests were performed (the results of the calculations were compared with the experimental measurements). In both cases, convincing results were obtained, which have confirmed the possibility of their use at the preliminary design stage of unmanned ship models.

Opis:

The main subject of the analysis was the activity and political concepts of lay Cath-olics who operated on the Polish political scene in the 1980s. This group of Catholic activists had been active in the public sphere for many years; in the 1980s, they orga-nized themselves in a Polish Catholic-Social Union. This community was not among the most important political parties of the then political system; it was not a major factor stabilizing the system or a major source of change. Nevertheless, it did have a prominent feature – it had a parliamentary representation and participated in political practice; it also had a limited impact on political decisions. The main motive of their actions was to promote Catholic values in the public sphere, but also an attempt to create a Catholic party, in the right circumstances. Still, there is a disagreement, both among researchers and actors of the political scene of the time, about the clear-cut assessment of their politi-cal commitment. Nonetheless, it probably can be said that their attitudes are within the concept of semi-opposition and paralegal opposition, and, to some extent, in what we understand by the term of opposition of value systems.

Opis:

Neuraminidase inhibitors (NAIs) are antiviral drugs for treatment and prophylaxis of influenza. By blocking the activity of the enzyme neuraminidase, NAIs prevent new viral particles from being released. The increasing use of NAIs brings into focus the risk of drug resistance arising to the class. There are three levels of antiviral resistance according to the way that resistance can be detected or inferred: genotypic, phenotypic and clinical resistance. For many years seasonal influenza viruses resistance to NAIs was low (0.33%). Recently, there has been described an increasing number of resistant seasonal influenza strains to oseltamivir (2% in adults, 5-18% in children). In 2007 there were published data describing 14% resistant to oseltamivir strains of influenza A/H1N1/ in Europe. Approximately 0.5-1.0% of influenza A/H1N1/pdm09 isolates are currently resistant to oseltamivir. The established markers of the resistance to oseltamivir were found in 2.4% of human and 0.8% of avian isolates of influenza A/H5N1/. It has been not observed a cross resistance among oseltamivir and zanamivir. NAIs resistance in influenza viruses is relative and despite its presence patients with resistant viruses may still benefit from receiving these antivirals. The response to treatment with antivirals remains the most important proof of antiviral effectiveness. The rational use of NAIs is essential to preserve the best choice for treatment and prophylaxis of seasonal, avian and pandemic influenza.

Opis:

An increase in the antibiotic resistance among Enterococcus faecium strains has been observed worldwide. Moreover, this bacteria has the ability to produce several virulence factors and to form biofilm that plays an important role in human infections. This study was designed to compare the antibiotic resistance and the prevalence of genes encoding surface protein (esp), aggregation substance (as), surface adhesin (efaA), collagen adhesin (ace), gelatinase (gelE), and hialuronidase (hyl) between biofilm-producing and non-producing E. faecium strains. Therefore, ninety E. faecium clinical isolates were tested for biofilm-forming ability, and then were assigned to two groups: biofilm-positive (BIO+, n =70) and biofilm-negative (BIO-, n = 20). Comparison of these groups showed that BIO+ isolates were resistant to β-lactams, whereas 10% of BIO- strains were susceptible to ampicillin (statistically significant difference, p = 0.007) and 5% to imipenem. Linezolid and tigecycline were the only antibiotics active against all tested isolates. Analysis of the virulence factors revealed that ace, efaA, and gelE genes occurred more frequently in BIO- strains (ace in 50% BIO+ vs. 75% BIO-; efaA 44.3% vs. 85%; gelE 2.9% vs. 15%, respectively), while hyl gene appeared more frequently in BIO+ isolates (87.1% BIO+ vs. 65% BIO-). These differences were significant (p < 0.05). We concluded that BIO+ strains were more resistant to antibiotics than BIO- strains, but interestingly, BIO- isolates were characterized by possession of higher virulence capabilities.

Opis:

Contemporary resistance scholarship increasingly positions individuals as agents operating within power relations and as such, this stimulating and diverse body of work illuminates the complexity of powerresistance. The richness of this academic engagement notwithstanding, there continues to be a paucity of work which offers a framework for conducting an analysis of resistance. In this article, we propose a general framework through which power-resistance can be coded, analyzed and theorized. Using data from an ethnomethodological study of 20 former longterm male prisoners in Canada, we demonstrate the usefulness of our 'resistance pyramid' to render visible the objectives, purposes, strategies, tactics and skills which characterize the processes, and not just the practices, of resistance. We argue that it is exactly these, often obscured, processes that allow us to appreciate the density of resistance-power, the multiple ways it operates and the significance of individuals' social, personal or political capital.

Opis:

The dominance of plastics in the packaging market is due to their low weight and thickness, which save transportation costs. However, their non-biodegradability poses a significant threat to the environment. Paper, on the other hand, is considered as a safer alternative due to its natural composition and biodegradability. The porous structure of paper limits its application in packaging, and its poor water resistance further restricts its use in humid environments. Therefore, lamination is a method useful tool to improve the barrier properties of paper. Additionally, the researchers are focusing on developing biodegradable and water-based coatings with anti-fat properties as a green alternative to plastic packaging. The impact of a new grease-resistant coating composed of starch, gelatin and sodium alginate on the mechanical properties of paper was investigated through tensile, tearing, and bursting strength tests. The results showed significant improvements in the mechanical properties of the coated paper sheets. Furthermore, the biodegradability test indicated that the paper samples coated with the new composition showed a 50% weight loss after one week of incubation in the soil, and after three weeks, they exhibited 100% weightloss, demonstrating their outstanding biodegradability.

Opis:

Numerical simulations of a pile jacking were carried out. A Coupled Eulerian–Lagrangian (CEL) formulation was used to treat with large deformation problems. An Abaqus, a commercial Finite Element Method software suit, was used as a computing environment. The Mohr–Coulomb constitutive model was applied and the Coulomb model of friction was used to describe pile-soil interaction. Calculations were made for three different pile diameters. Toe and shaft unit resistances versus depth for each pile were investigated and plotted. CPT-based solutions were compared with the results of numerical simulations.

Opis:

In vitro antileukemic activity of five glucocorticoids and their cross-resistance pattern in childhood acute lymphoblastic and non-lymphoblastic leukemia were determined by means of the MTT assay in 25 leukemia cell samples of childhood acute leukemias. The equivalent antileukemic concentrations of the drugs tested were: 34 μM hydrocortisone (HC), 8 μM prednisolone (PRE), 1.5 μM methylprednisolone (MPR), 0.44 μM dexamethasone (DX) and 0.22 μM betamethasone (BET). In comparison with initial ALL cell samples, the relapsed ALL group was more resistant to PRE (38-fold, p = 0.044), DX (> 34-fold, p = 0.04), MPR (38-fold), BET (45-fold) and HC (33-fold). The AML cell samples were even more resistant to: PRE (>85-fold, p=0.001), DX (> 34-fold, p = 0.004), MPR (> 69-fold, p = 0.036), BET (> 69-fold, p = 0.038) and HC (54-fold, p = 0.059) when compared with ALL on initial diagnosis. A significant cross-resistance among all the glucocorticoids used was found. Only in some individual cases the cross-resistance was less pronounced.

Opis:

There are two sides of the catalyst operation: favourable and adverse. The positive side can be expressed by a conversion rate of harmful substances which is the principal parameter of catalyst work in respect of ecology. However, resistance of exhaust gas flow through the catalytic converter is also an essential problem. This is just the negative, adverse side of the converter operation. The catalytic converter can be treated as a local or linear resistance element of exhaust system. The first model, in which flow resistance generated by a catalyst is treated as local resistance, is more simplified. It is especially useful in case, when detailed constructional data of converter are unknown and the analysis of flow resistances in exhaust system is necessary. The basic measured quantity of flow resistance is pressure drop of exhaust gas within the catalyst. Next, on the basis of taken measurements also resistance number for the tested catalyst is calculated and analysed. Resistance number of the converter is calculated using Darcy model. In the second case, exhaust gas flow resistance through catalyst is treated as linear resistance with energy dissipation (linear frictional resistance) distributed linearly along way of exhaust gas flow. Friction number for the tested converter is calculated and analysed. The problem has been illustrated by the results of experimental researches of the three-way catalytic converter installed in the exhaust system of the spark ignition engine.

Opis:

This review summarizes current data on resistance among Salmonella spp. isolates of food origin from countries in different regions of the world. The mechanisms of resistance to different groups of antimicrobial compounds are also considered. Among strains resistant to quinolones and/or fluoroquinolones the most prevalent mechanism is amino acid substitutions in quinolone resistance-determining region (QRDR) of genes gyrA, parC but mechanism of growing importance is plasmid-mediated quinolone resistance (PMQR) associated with genes qnrA, qnrB, qnrC, qnrD, qnrS but frequency of their detection is different. Resistance to sulfonamides is mostly associated with genes sul1 and sul2, while resistance to trimethoprim is associated with various variants of dhfr ( dfr) genes. Taking into account Salmonella spp. strains isolated from food, resistance to β-lactams is commonly associated with β-lactamases encoding by blaTEM genes. However strains ESBL and AmpC – positive are also detected. Resistance to aminoglicosides is commonly result of enzymatic inactivation. Three types of aminoglycoside modifying enzyme are: acetyltransferases (AAC), adenyltransferases (ANT) and phosphotransferases (APH). Resistance to tetracyclines among Salmonella spp. isolated from food is most commonly associated with active efflux. Among numerous genetic determinants encoding efflux pumps tetA, tetB, tetC, tetD, tetE and tetG are reported predominatingly. One of the most common mechanisms of resistance against chloramphenicol is its inactivation by chloramphenicol acetyltrasferases (CATs), but resistance to this compound can be also mediated by chloramphenicol efflux pumps encoded by the genes cmlA and floR. It is important to monitor resistance of Salmonella isolated from food, because the globalization of trade, leading to the long-distance movement of goods, animals and food products, encourages the spread of resistant pathogens around the world.
W artykule przedstawiono aktualne dane na temat mechaniznów lekooporności pałeczek Salmonella spp. pochodzących z żywności. Wśród szczepów opornych na chinolony i/lub fluorochinolony najczęściej identyfikowanym mechanizmem są substytucje aminokwasów w obrębie regionów determinujących oporność na chinolony (QRDR-quinolone resistancedetermining region) w genach gyrA i parC, jednak coraz częściej identyfikowane są geny qnr (qnrA, qnrB, qnrC, qnrD, qnrS) związane z plazmidami (PMQR - plasmid-mediated quinolone resistance). Oporność na sulfonamidy jest najczęściej związana z genami sul1 i sul2, natomiast różne warianty genów dhfr ( dfr) warunkują oporność na trimetoprim. Biorąc pod uwagę szczepy Salmonella spp. pochodzące z żywności, oporność na antybiotyki β-laktamowe związana jest zazwyczaj z produkcją β-laktamaz kodowanych przez geny blaTEM. Jednakże coraz powszechniej identyfikowane są szczepy produkujące β-laktamazy o rozszerzonym spektrum substratowym (ESBL) oraz cefalosporynazy AmpC. Oporność na aminoglikozydy najczęściej wynika z wytwarzania enzymów modyfikujących cząsteczki leku: acetylotransferaz (AAC), adenylotransferaz (ANT) oraz fosfotransferaz (APH). Oporność wobec tetracyklin wśród pałeczek Salmonella spp. izolowanych z żywności najczęściej związana jest z mechanizmem aktywnego usuwania leku za pomocą pomp (efflux) kodowanych, najczęściej przez geny tetA, tetB, tetC, tetD, tetE i tetG. Jednym a najczęściej wykrywanych mechanizmów oporności na chloramfenikol jest jego inaktywacja w wyniku działania acetylotransferazy chloramfenikolowej (CAT). Oporność na chloramfenikol może być również związana ze zjawiskiem aktywnego wypompowywania leku. Pompy efflux są kodowane przez geny floR (warunkujące oporność także na florfenikol) lub cml. Istotne znaczenie ma monitoring lekooporności wśród szczepów Salmonella spp. pochodzących z żywności, ponieważ transport środków spożywczych oraz zwierząt do i z krajów całego świata ułatwia rozprzestrzenianie się szczepów lekoopornych.

Opis:

Quality of surface finishes for beech stairs. The article deals with quality of oil varnish surface finish when compared with a standard polyurethane finish. The manufacturer recommends both surface finishes to be used for stairs. The tested surface finishes were created on beech wood according to producer recommendations. The quality comparison was based on three mechanical properties of the surface finishes: the surface hardness, impact resistance, and resistance to abrasion. The selected properties gave a good indication for suitability of the tested coating materials for stairs. Both surface finishes achieved the same surface hardness – grade of 11, as measured by the pencil scratch test. The impact resistance measured at low drop height (50 and 100 mm) was better for the oil varnish surface than for polyurethane one. At higher drop heights, the impact resistance of both surfaces was the same. The resistance to abrasion of the oil varnish was better than the resistance of the polyurethane one.
Jakość wykończenia powierzchni schodów bukowych. W ramach badań porównano jakości wykończenia powierzchni drewna utwardzonym olejem do standardowego wykończenia lakierem poliuretanowym. Obydwa wyroby przeznaczone są do wykańczania powierzchni schodów. Badane powłoki wytworzono na drewnie bukowym zgodnie z zaleceniami producenta. Dla wytworzonych powłok porównano: twardości powierzchni, odporności na uderzenia i odporności na ścieranie. Uzyskane wyniki potwierdziły możliwość wykorzystania obydwu środków do wykańczania powierzchni elementów schdów. Obie badane powierzchnie charakteryzowały się tym samym poziomem twardości powierzchni - stopień 11 (metoda zarysowania ołówkiem). Powierzchnia wykończona utwardzonym olejem charakteryzowała się wyższą odpornością na uderzenia przy niskiej wysokości rzutu (50 i 100 mm) w porównaniu do powierzchni z powłoką poliuretanową. Przy wyższych wysokościach rzutu odporność na uderzenia obu powierzchni była taka sama. Powierzchnia wykończona utwardzonym olejem charakteryzowała się również wyższą odpornością na ścieranie.

Opis:

The climate of our planet is changing, which, scientists believe, is caused by the production of greenhouse gases (GHG). To stabilize the concentrations of those gases in the atmosphere, it is necessary to decrease their production. Since transport is one of the major sources of GHG emissions, the most obvious solution is to decrease fuel consumption by vehicles. The amount of fuel used by a vehicle depends directly on the force of driving resistance, including rolling resistance and air resistance. The aim of the article is to indicate one of the easiest possibilities of decreasing these resistances. A small change in the shape of a vehicle’s frontal area leads to a significant reduction in air resistance.

Opis:

Amulti-tips horizontal sensor was developed and mounted horizontally on a tine face by shafts. The length of shafts was reduced from top to down the tine. The developed system was evaluated in the controlled soil bin laboratory conditions with clay loam soil and uniform soil moisture content. The experiment was designed with soil compaction at three levels of uniform and nonuniform soil compaction in completely randomized block design with four replications. Vertical standard penetrometer was also used to compare with horizontal sensor data at whole working depth of 0 to 400 mm. The results indicated that there is a correlation with R2 = 0.86 between soil cone penetrometer values and the horizontal soil mechanical resistance measurement system data. It can be concluded that the idea of reducing the length of the tips from top to down the tine face would give promising results.

Currently, due to the economic and ecological aspects, light alloys are increasingly important construction material, in particular in the transport industry. One of the popular foundry magnesium alloys is the alloy AZ91, which among others due to mechanical properties and technological features, is used, for example, for light structural parts. The paper presents the results of research on modification of the AZ91 alloy surface layer in the plasma electrolytic oxidation process. The change of usable properties of the produced coatings was obtained by introducing additions of silicon carbide or boron nitride. The thickness and hardness of the protective layers produced, resistance to scratches and corrosion resistance were determined. Moreover, the friction coefficient of the coating-steel pair was investigated. The quality of the connections made between the coating and the substrate, i.e. the magnesium alloy, was also evaluated. The results obtained for coatings with silicon carbide or boron nitride additives were always compared to the results obtained for unmodified samples. On the basis of the obtained results, it was shown that the introduction of boron nitride additive to the AZ91 alloy coating produced in the plasma electrolytic oxidation process significantly improves the resistance to: (i) corrosion and (ii) abrasive wear of the coating.

We demonstrate that these events are accompanied by a significant increase in plastoquinone (PQ) level. It is postulated that PQ may be associated with mechanisms maintaining a tightly controlled balance between the accumulation of ROS and antioxidant activity that determines the full expression of effective defence.

Opis:

Tuberculosis (TB), an infectious disease caused by Mycobacterium tuberculosis (M.tb), remains a leading public health problem in most parts of the world. Despite the discovery of the bacilli over 100 years ago, there are still many unanswered questions about the host resistance to TB. Although one third of the world's population is infected with virulent M.tb, no more than 5-10% develop active disease within their lifetime. A lot of studies suggest that host genetic factors determine the outcome of M.tb-host interactions, however, specific genes and polymorphisms that govern the development of TB are not completely understood. Strong evidence exists for genes encoding pattern recognition receptors (TLR, CD14), C-type lectins, cytokines/chemokines and their receptors (IFN-γ, TNF-α, IL-12, IL-10, MCP-1, MMP-1), major histocompatibility complex (MHC) molecules, vitamin D receptor (VDR), and proton-coupled divalent metal ion transporters (SLC11A1). Polymorphisms in these genes have a diverse influence on the susceptibility to or protection against TB among particular families, ethnicities and races. In this paper, we review recent discoveries in genetic studies and correlate these findings with their influence on TB susceptibility.

The test results are made for both the bare hull and the hull with appendages (skeg, azimuthal propeller). Significant differences between results of the theoretical methods and experimental ones, especially in the case of the model with skegs and propulsion, are pointed out. The purposefulness of using several parametric methods and the use of average results at the preliminary design stage were also discussed.

Opis:

As the backgound for the opinions of the Bible on the stat, this article presents briefly the history of Israel, divided into two main periods: national monarchy (earlier period of the Old Testament) and submission to the foreign powers (later books of the Old Testament and the New Testament). The opinions of the Old Testament on the own state hesitate between hope and disappointment, between optimism (royal ideology and messianism, tasks of the king, principles of government) and criticisms (Judges 9, 1 Samuel 8-12, bad kings). A moderate conclusion is offered by the Pentateuch (law above politics, Deut 17). In the attitudes towards the empires, we find two contradictory currents: submission to foreign rule and resistance. In the New Testament we find an acceptation of the state in the New Testament (Mark 12 on taxation, authority from God in Romans 13, 1 Cor 12.12-30), but also criticisms, triggered by persecutions (life of Jesus and Paul, Rev 13-19 and the satanic side of the empire). The state has its lawful authority, both instituted and limited by God and his law. This institution has some justification, but also serious vices (godlessness, violence, high taxes). However, the citizens should obey the state which deals justly with them.

In this long-term study Fhb1 on chromosome 3BS and Qfhs.ifa-5A located on chromosome 5A were introgressed into European elite spring and winter wheat to test effects on FHB resistance and side effects on agronomic performance and F. graminearum isolates and mixtures. The introgression of the QTL Fhb1 and Qfhs.ifa-5A from the Sumai 3-descendant CM82036 could be performed in the shortest possible way by marker-assisted backcrossing. They were both validated in European elite wheat background. Effects on FHB resistance were, on average, only about half of the effect in the original mapping populations. In the best phenotypically and marker-selected BC0 line of spring wheat FHB was reduced from 40 to 4.3% of disease symptoms by introgressing both QTL, in the best BC3 line of winter wheat the reduction was 28 and 37% for the moderately resistant and highly susceptible recurrent parent, respectively. Introgression of both QTL simultaneously did not result in significantly higher FHB resistance than introgression of only one of both QTL. Small significant negative effects on grain yield were detected in the Anthus but not in the Opus BC3F2:5 backcross population when both QTL were introgressed. Backcrossing with only Qfhs.ifa-5A did not reduce grain yield significantly. Differences in heading date, plant height and quality traits were in all cases small although often significant. Selection of lines with improved resistance level and similar high yield level like the recurrent parent was feasible. Stability of FHB resistance mediated by both QTL was stable across 22 Fusarium isolates from Europe and Canada and six binary mixtures. Competition effects between isolates in mixtures were obvious but could not be attributed to the resistance of the host. In conclusion, marker-based backcrossing is a feasible option for introgressing Fhb1 or Qfhs.ifa-5A QTL into the high-yielding, quality-oriented European wheat gene pool.

Opis:

Three types of sintered alloys were fabricated based on cobalt, nickel and high-temperature alloy ZhS32-VI matrix with titanium carbide strengthening phase. TiC content was in a range of 30–50 vol. %. The melting temperatures of alloys are higher than 1320°C, and they may undergo undamaged through all technological procedures together with turbine blades, including soldering and outgassing. DSC analyses indicates no additional thermal effects until melting, which confirms their structural stability. The examinations of microstructure revealed three types of constituents – TiC particles, matrix solid solution and blow outs – structural defects having negative effects on all the studied properties. It was found that heat resistance of nickel based sintered alloys at the temperature of 1100°C is superior as compared with the alloys based on cobalt and alloy ZhS32-VI. It has been established that wear resistance in conditions of fretting wear at temperatures of 20, 850, 950 and 1050°C of sintered alloy with ZhS32-VI matrix is mostly superior as compared with the other alloys. The properties of produced alloys allow to use them for manufacturing of components of friction couples operating in conditions of high temperature fretting wear, including protective pads of turbine blades top shrouds contact faces.

Opis:

Resin concretes belong to a small group of building materials which, besides high strength parameters, also have a very good chemical resistance. This is confirmed by the studies carried out by various research institutions around the world. However, there is little data on the behaviour of composite resin exposed to corrosive solutions for an extended period of time. This article presents the results of the research on weight changes in samples of epoxy mortar modified with poly(ethylene terephthalate) glycolysates, immersed for 5 years in four different aggressive media i.e. 10% aqueous solutions of sulphuric and nitric acids, sodium hydroxide, and sodium chloride. The actual average weight changes obtained were compared with the data calculated on the basis of the regression functions fitted to the data recorded after 3.5 years of exposure. This allowed verification of the model selection correctness and evaluation of the effectiveness of the fitted regression curve. In the case of aqueous sodium hydroxide and sodium chloride solutions, it can be assumed that the logarithmic model describes weight changes well. It was observed that the weight of the samples exposed to NaCl solutions and NaOH stabilizes over prolonged monitoring time and reaches a plateau. However, the weight changes in mortar samples immersed for 5 years in aqueous solution of sulphuric and nitric acids quite significantly differ from the data calculated on the basis of the trend line fitted to the results of the tests carried out after 3.5 years of exposure. It seems that the better solution in this case is the selection of an exponential model. In addition, placing the logarithmic trendlines for all corrosive media together on a chart allows to note which of the solutions is the most aggressive. It was found that after 5 years of immersion in aqueous solutions of acids, mortar samples became brittle, and the observation of their fractures confirmed the weakness of the connection on the resin/aggregate phase boundary. Changes in the appearance of the samples were also noted, namely the surface of samples submerged in a solution of nitric acid strongly yellowed, and those treated with sulphuric acid were tarnished.

Opis:

In recent years, there has been a rapid increase in the incidence of Candida infections. The different species of the genus Candida vary in their virulence abilities and susceptibility to antifungal agents, depending on several external factors. The result of such modifications may be cross-resistance, which is understood as an acquired resistance to a certain antimicrobial agent after exposure to another drug. The aim of this study was to determine the possibility of cross-resistance between fluconazole, voriconazole, itraconazole, and methotrexate in Candida albicans and Meyerozyma guilliermondii (syn. Candida guilliermondii). Fifteen strains of M. guilliermondii and eight strains of C. albicans, including the standard strains, were tested. For all strains, the minimum inhibitory concentrations (MICs) for fluconazole, voriconazole, and itraconazole were determined before and after stimulation with methotrexate. The median MICs in M. guilliermondii before and after stimulation were 9.333 and 64 mg/L (p = 0.005) for fluconazole; 0.917 and 1.667 mg/L (p = 0.001) for itraconazole, respectively. No significant change in MIC was observed for voriconazole. For C. albicans strains, the median MICs before and after stimulation were 0.917 and 64 mg/L (p = 0.012) for fluconazole; 0.344 and 1.135 mg/L (p = 0.018) for voriconazole, respectively. There was no significant change in MIC values for itraconazole. Thus, this study demonstrates the presence of cross-resistance between voriconazole, itraconazole, fluconazole, and methotrexate for the selected strains. Methotrexate exposure induces different responses when certain drugs are used for various species. Therefore, if a patient was previously exposed to methotrexate, there may be a higher risk of treatment failure with fluconazole than with other azoles such as voriconazole for fungemia caused by M. guilliermondii or itraconazole for C. albicans infection.

Opis:

The article addresses the presence of the avant-garde in the discourse and the practice of social resistance in Serbia at the turn of the 20th and 21st centuries. The focal point of the text is the thesis that nowadays the avant-garde resonates not so much as an artistic formation, but as an ideological complex. The author investigates the manners of contemporary transposition of ideas and avant- garde imagination through the analysis of the activities of the Centre for Cultural Decontamination in Belgrade. Using the examples of two programmes: Modernism, Serbian National Identity in 20th Century and En Garde – Avant-Garde 20/21, the author shows how the local experience of the interwar avant-garde and the neo-avant-garde formed within the movement of ʼ68 protests, creates a specific ideological current, a model of self-organization and a pattern of activities bordering between art and socio-political reality. In the 1990s, in Serbia, it becomes the reference system for artivism (an approach consisting in influencing social and political reality through art), and today still remains an inspiration for independent intellectual and artistic environments and for critical institutions that create an alternative and polemic cultural space to the official policies of the Serbian authorities.

Opis:

Antibiotic resistance of microorganisms is a phenomenon widely reviewed in literature that could lead to the outbreak of diseases difficult to control by available pharmaceuticals, or even an epidemic. Wastewater treatment plants act as specific reservoirs of resistance, as contained in the wastewater antibiotics, antibiotic resistance bacteria and antibiotic resistance genes could lead to the phenomenon of spread of resistance - inside wastewater treatment plant, but also among strains that dwell in the environment, after the discharge of inadequately treated wastewater to the receiver. Technological systems in working treatment plants do not stop sufficiently the transfer of determinants of resistance to the environment, or do not provide the effective disposal. Therefore, it is necessary to look for new solutions or methods for wastewater treatment and monitoring of treated sewage, sludge and atmospheric air around treatment plants in the aspect of antibiotic resistance.

Opis:

The efficiency of a Thermoelectric Module (TEM) is not only influenced by the material properties, but also by the heat losses due to the internal and contact thermal resistances. In the literature, the material properties are mostly discussed, mainly to increase the well-known thermoelectric figure of merit ZT. Nevertheless, when a TEM is considered, the separate characterization of the materials of the p and n elements is not enough to have a suitable TEM electrical model and evaluate more precisely its efficiency. Only a few recent papers deal with thermal resistances and their influence on the TEM efficiency; mostly, the minimization of these resistances is recommended, without giving a way to determine their values. The aim of the present paper is to identify the internal and contact thermal resistances of a TEM by electrical characterization. Depending on the applications, the TEM can be used either under constant temperature gradient or constant heat flow conditions. The proposed identification approach is based on the theoretical electrical modeling of the TEM, in both conditions. It is simple to implement, because it is based only on open circuit test conditions. A single electrical measurement under both conditions (constant-temperature and constant-heat) is needed. Based on the theoretical electrical models, one can identify the internal and thermal resistances.

The paper presents the concept of fractional resistance of materials, including some basic principles of determining material resistance to individual cavitation load fractions, prediction of erosion curves under predetermined cavitation load and retrieval of his load basing on errosion curves of some reference materials. The consideration is illustrated by results of analysing aluminium alloy (PA2) and Armco iron (E04) erosion curves determined in a cavitation tunnel with a slot-type cavitator. The results attained prove unambiguously correct functioning of the software developed.

Opis:

The multixenobiotic resistance (closely related to multidrug resistance) system controls transport across the plasma membrane as a defense against toxic molecules. Multixenobiotic resistance system consists of an efflux pump, ABCB1 (also named P-glycoprotein, P-gp), and/or a molecule of the ABCC family (also named multiple resistance associated protein, MRP). ABCB1 is able to increase efflux of many low-molecular foreign molecules. Measuring system induction may be used as a biomarker of cell/organism exposure to foreign substances. Various established cell lines were tested for constitutive and induced multixenobiotic resistance proteins by Western blotting immunodetection. The pumping function was indirectly assayed with Rhodamine B by visualization of cell fluorescence in the presence of verapamil. Changes in ABC proteins were measured by flow cytometry after exposition to various perfluorinated carboxylic acids. MCF7 and HeLa cells were found to contain the highest constitutive level of both ABCB1 and ABCC1. HEK293 exhibited much less ABCB1 and no activity of pumping out Rhodamine B. The pumping activity was found to be related to the amount of the cell-type specific 170 kDa ABCB1 protein. An 8-day exposure to 10-4 M perfluorononanoic acid resulted in about 2-2.5-fold increase of ABCB1 level. That was confirmed also for short times by flow cytometry of cells exposed to perfluorinated acids and its natural congeners. Both ABCB1- and ABCC1-related fluorescence increased along with the carbon chain in acids from C6 up to C9 and decreased for C10. Measuring of multixenobiotic resistance changes in vitro induced by chemicals may be a convenient test for screening for their potential toxicity.

Opis:

This paper utilised computational fluid dynamics (CFD) technology to calculate the resistance of a novel high-speed quadramaran in calm water using the Navier‒Stokes (N‒S) equation, analysed the total resistance, frictional resistance, and residual resistance characteristics of this novel high-speed quadramaran at different length Froude numbers, and compared them with the results of a conventional high-speed catamaran with the same displacement. The results showed that the total resistance of the quadramaran had a significant hump at the Froude number of 0.6, due to the complexity of the wave interference among the four demihulls, and the hump value was about 1.6 times that of the catamaran. Above the hump speed, the total resistance of the quadramaran decreased with the increase of the Froude number, until reaching the Froude number of 1.06, when the curve became flat, and it showed a maximum resistance reduction of 40% at the Froude number of 1.66 compared with the catamaran, where the total resistance curve was steep. The frictional resistance of the quadramaran increased gradually with the growth of the Froude number, which was basically consistent with the change trend of the catamaran. The residual resistance of the quadramaran first rose and then reduced with the rising Froude number, the curve showed a large hump due to the adverse wave interference, and the hump value was about 1.7 times that of the catamaran. Above the Froude number of 1.06, as the wave interference changed from adverse to favourable, the quadramaran had lower residual resistance than the catamaran. The bow and stern demihulls of the quadramaran were also analysed for their resistance characteristics. The total resistance of the bow demihulls increased gradually with the increase of the Froude number, the curve had a small hump at the Froude number of 0.7, and above the hump speed, the curve was steep. The total resistance of the stern demihulls first increased and then decreased with the growth of the Froude number, the hump value at the Froude number of 0.85 was significant and was about 2 times that of the bow demihulls, and the curve became flat above the Froude number of 1.51.

Opis:

Background. Antimicrobial resistance is an emerging problem worldwide, having a negative influence on patient outcomes. As compared to high and upper middle-income countries, the condition is miserable in low- and middle-income countries, including Pakistan. Objectives. This study aims to assess the perception of physicians concerning antibiotic use and resistance, the factors influencing the prescription of antibiotics and interventions to improve the prescribing behavior in Pakistan. Material and methods. A cross-sectional survey was performed among physicians practicing in different hospitals of Lahore, Pakistan. A 60-item survey instrument was developed in consultation with a group of experts after a literature review of previous comparable studies. The questionnaire was distributed to physicians practicing in different healthcare settings of Lahore, Pakistan. Results. A total population of 200 physicians filled in the questionnaire, with a response rate of 72.7%. The majority of physicians were younger (n = 124, 62%), with an age group of 23–29 years. Most of the physicians reported that antibiotics are overused nationally (n = 190, 95%). However, they did not always agree that antibiotics are overused in their own institutions. A majority of physicians believed that strong knowledge of antibiotics is important in their career (n = 184, 92%). Of the total, 176 (88%) physicians believed that inappropriate use of antibiotics is professionally unethical. Conclusions. Our findings showed that physicians are well aware of the importance of antibiotic resistance and reported that rational use of antibiotics will aid in resolving this issue. Therefore, the introduction of educational sessions regarding antibiotic use and its resistance and innovative approaches to attract healthcare practitioners’ attention towards antibiotic stewardship programs are urgently needed

Opis:

The machine construction sector uses from 2 to 5% of thermoplastic polymer production. This material is used to make small elements and big parts of equipment, including guards. The latter have mechanical vibration damping capacity, do not require any maintenance, are cheap and look attractive. Moreover, polymer guards are an essential element of machines as they improve workplace safety. They are used in such machines as lathes, milling machines, drills, extruding machines, presses and grinders. Pursuant to the Ordinance of the Minister of Labour and Social Policy on general provisions for safety and health at work, protective devices used in machines should be strong and durable so as to ensure the appropriate level of occupational safety. This is why the selection of the right material to make such devices is essential. Most frequently guards used in the market are steel frames with a polycarbonate screen or laminated safety glass. Other materials used to manufacture guards are poly(methyl methacrylate) (PMMA) and polystyrene (PS). Thermoplastics are characterised by high visual light transmittance (even up to 98% in the case of PMMA), easy treatment, possibility to form any shape and resistance to atmospheric factors. However, they are also characterised by limited high temperature resistance, low fire resistance and high speed of fire propagation on their surface which may be dangerous for employees in case of fire. The article discusses the selection of appropriate material for the production of guards in the context of their exploitation in higher temperature conditions and examines threats posed by thermoplastics in fire conditions.

The Kurds, the largest minority in Turkey, have almost no visibility in Turkish sports. While Kurdish sportspeople are not discouraged from joining in sports activities, their participation is heavily monitored by the government agencies against any manifestation of ethnic identity. Football in the Kurdish regions, seen by the Turkish state as a tool to distract Kurdish youth from political activities, has always been subject to the direct intervention of the civil and military bureaucracy, their presence in club boards is not uncommon. However, a third-division club named Amedspor, challenged all the unwritten rules related to Kurds in sports, at the expense of receiving a recurring suspension from the Turkish Football Federation. This article examines the Kurdish sports and the Amedspor case through Manuel Castells’ conception of legitimizing, resistance and project identities

Opis:

The barbell squat is a fundamental strength and conditioning exercise, with two principal variants; back and front. Whilst previous studies have examined the mechanical differences of the front and back squat, there is no information comparing the distributions of muscle forces between these variants. This study aimed to compare estimated forces developed by the primary skeletal muscles used in the front and back squat. Twenty-five male participants were recruited with 6.24 ±2.21 years of experience in squat lifting and 1 repetition maximum values of 127.5 ±18.8 and 90.6 ±14.4 kg for the back and front squat lifts. Participants completed both back and front squats at 70% of their front squat 1 repetition maximum. Muscle forces were determined during dynamic situations using motion capture data, in addition to sagittal plane kinematics. Differences between squat conditions were examined using a multivariate analysis of variance. The kinematic analysis showed that the back squat was associated with significantly (p < 0.05) greater flexion of the trunk. Examination of muscles forces indicated that erector spinae forces were also significantly (p < 0.05) larger in the back squat. No significant differences were identified for skeletal muscle forces elsewhere (p > 0.05). Our results indicate that neither the front nor back squat provides any marked difference in muscle force production, aside from that isolated to the lower back. These findings lead the conclusion that neither the front nor back squat conditions confer any additional benefits over the other in terms of the skeletal muscle force output.

Opis:

A phenomenon of increasing resistance of Candida spp. to azoles has been observed for several years now. One of the mechanisms of lack of sensitivity to azoles is associated with CDR1, CDR2, MRD1 genes (their products are active transport pumps conditioning drug efflux from pathogen's cell), and ERG11 gene (encoding lanosterol 14α-demethylase). Test material was 120 strains of Candida albicans (60 resistant and 60 susceptible to azole drugs) obtained from clinical samples. The first stage of experiment assessed the expression of CDR1, CDR2, MDR1 and ERG11 genes by Q-PCR. The impact of ERG11 gene's mutations on the expression of this gene was analysed. The final stage of the experiment assessed the level of genome methylation of Candida albicans strains. An increase in the expression of CDR2, MDR1 and ERG11 was observed in azole-resistant strains of Candida albicans in comparison to strains sensitive to this class of drugs. Furthermore, 19 changes in the sequence of ERG11 were detected in tested strains. Four of the discovered mutations: T495A, A530C, G622A and A945C led to the following amino acid substitutions: D116E, K128T, V159I and E266D, respectively. It has also been found that statistically five mutations: T462C, G1309A, C216T, C1257T and A945C affected the expression of ERG11. The applied method of assessing the level of methylation of Candida albicans genome did not confirm its role in the development of resistance to azoles. The results indicate however, that resistance of Candida albicans strains to azole drugs is multifactorial.

“Depressed Sufferings”: Reading Dalit Life-Writings as Testimonies of Collective Resistance

Opis:

Dalit life-writings have often been identified as reified spaces of protest against the Brahmanic oppression continuing since centuries in the Indian society. Banished to a space of invisibility, both metaphorical as well as physical margins of the Social Imaginary, Dalits continue to push back boundaries by transforming the ‘marginal’ space into a space of ‘subaltern resistance’. My aim in this paper is to interrogate the methods of collective resistance in the life-writings of Dalit women authors and show how the peripheral spatial geography becomes the central site of resistance. Both Baby Kamble’s The Prisons we Broke (2008), and Bama’s Karukku (1992) belong to entirely different historical periods, and therefore, inevitably differ in their plot-narratives and manner of expression. However, they converge in their emphasis on how the Dalit segregated spaces in their village assume an important role in awakening their collective consciousness first – as members of a community, and second – as women. Both Karukku and The Prisons We Broke refuse to adhere to the Augustinian definitions of the autobiography as a genre and instead become works which elude generic conventions of the autobiography, anticipating a separate literary genre for themselves. In fact, the closest literary referent of these texts is the Latin American genre of the testimonio - social and political narratives of witnessing significant events as a collective -  that emerged in the 1960s. Reading these Dalit life-writings as testimonios of collective resistance is evocative of the on-going struggle of the Dalits to claim a separate space, both social and literary, while lending a voice to their lived-experiences in a paternalistic society that is essentially casteist.    Baby Kamble and Bama raise pertinent questions against the dominant religious ideology and contribute to a social change in the conditions of women. Thus, my second intention in the paper is to closely look at the resistance offered against religious bias by the two authors. Since the Indian caste system derives its justifications from the Hindu law of divinity that are apparently inalterable according to Hindu purists, challenging the ‘savarna’ customs and rituals has been a persistent preoccupation within Dalit activism. Foregrounding textual instances of such challenges and resistance shall help us in understanding how a society practices coercion against a community when it comes to something as benign and as personal as man’s spiritual connection with the divine force.

Large demand for bulk of sapphire optical products, which are widely used as illuminators, optical windows in aviation and aeronautics etc., generates the inquiry of effective production of high quality industrial crystals. The technology of crystal growth with the horizontal single crystal sapphire crystallization method is based on putting the crystal seed into the front of the crucible resistant to temperatures up to 2150°C. Without encompassment of the production technology of this special container made from thin molybdenum sheet is not realistic to consider the productive exploitation of horizontal crystallization systems in engineering practice. This paper presents the analysis of the possibility of the local resistance of molybdenum sheet heating by its deep drawing to obtain better drawing properties by increased blank temperature.

Opis:

Te paper focuses on the identity of a contemporary Polish nationalist movement. It is based on biographical narrative interviews which were carried out among members of three Polish nationalist organizations: the All Youth Polish, the National Rebirth of Poland and the National Radical Camp. Participants of nationalist movements mobilize themselves and protest against increasing diversity. Te contemporary Polish nationalism can be understood as the particular kind of cultural resistance to globalization, cultural diversifcation, lef- -wing activities. Te homosexuals and feminists seem to be their main opponents. Nationalists defne themselves as the defenders of tradition, history and Polish values and hence they attempt to make the public sphere homogeneous. According to their statements, the public sphere should be reserved for Polish, Catholic values and norms. As I conclude, the nationalist resistance can be perceived as the result of anxiety for the status of national identity and longing for universal values or constant points of reference.

Opis:

Genetic resistance against Pythium species would be an efficient control of this major seed and seedling fungal pathogen in safflower (Carthamus tinctorius), but so far no source has been identified. Therefore, identifying and then incorporating genetic resistance into the cultivars would be an ideal method of control for this disease. So in this study the resistance to seed rot and damping-off caused by Pythium ultimum among seventeen genotypes of safflower collected from all major production regions of the crop in Iran and some other countries was investigated. Pythium ultimum, previously identified as the most prevalent Pythium isolates on safflower, were used to infest the sterilized soil, which was seeded with safflower genotypes in greenhouse conditions. The experiment was conducted as a split plot design in which sterile and Pythium-infested soils were considered as main plots, and seventeen genotypes of safflower were sub plots. In sterile media, percent of seedling emergence (SES) and in Pythium-infested media, percent of seedling emergence (SEI), percent of diseased seedlings (DSI), percent of uninfected seedlings (USI) and percent of non-emerged seeds (NSI) were recorded. Symptoms showed that in safflower, damping-off occurred in both forms of pre and post emergence. Genotypic variation was existed for level of susceptibility to P. ultimum. Significant differences in SES and SEI were detected among safflower genotypes (P < 0.01), and a significant correlation between SES and seed weight (P < 0.05); SES with SEI (P < 0.05) were detected. Result showed that between evaluated genotypes there wasn’t any genotype with complete resistance (100%) to P. ultimum, so the susceptibilities were assayed. Based on the assessed variables, genotypes LRV-55-295, Aceteria, PI-250537 and IL-111 appear to be highly susceptible to the Pythium infection, whereas 34040, Arak281, and Isfahan were the least susceptible to the disease. Further research will be conducted to determine whether the resistance detected in these genotypes is heritable...

Opis:

The article describes the effect of substrate roughness on the generation of air flow resistance and the occurrence of kinetic friction. These are the two main factors influencing reduction in wind speed, lack of ventilation in built-up areas, and stagnation of pollution over areas with high substrate roughness. The work presents the results of the authors’ own measurements in the field, carried out using WindLog and CHY 361 anemometers, in two different types of atmospheric conditions - sunny and rainy weather. The measurements were taken on a stretch of the Rudawa River, located on the Cracow city limits. Wind speed was measured at all established measurement points. The immediate surroundings of the points varied in terms of how densely the areas were built up. The effect of changes in the shape and equivalent diameter of the measurement profile on the magnitude of flow resistance and friction was also tested. The results of the study indicate that the best type of arrangement for buildings around the valley of the Rudawa River is a latitudinal configuration. The lack of buildings on the path along which the airstream flows creates suitable conditions for ventilation of the city, and thus for clearing the air of pollution. In the event of construction on a north-south axis it is important to avoid erecting tall and very tall buildings in the area.

Opis:

The text undertakes the problematics situated between modernity and tradition regarding the reception of H.A. Giroux’s works in Poland, in a view of furthering the study of pedagogy and educational praxis. First, the author outlines the beginnings of openness towards critical pedagogy. What is underscored here is the 1980s’ main inspiration drawn from the resistance paradigm. Then, the author proceeds to the current state of Giroux’s reception in Poland. He illustrates differences among particular examples and levels of the said reception of Giroux’s pedagogy and of the scholar’s theoretical background. The emphasized disputes pertain especially to transcending metaphysics and relativism as a challenge faced by hermeneutical criticism and critical hermeneutics. Additionally, the “critical” horizon of the main handbook of pedagogy used in Polish universities is discussed. The author point to the wasteful efforts at instigating the breakthrough in the reception of critical pedagogy and he exemplifies them by an instance of misbegotten analysis of the allegedly delayed critical pedagogy of work. As a particularly positive example the author presents a new effort at developing critical hermeneutics (and radical praxis) for pedagogy by Andrzej Wierciński. In the concluding part written “in lieuof conclusions,” four lists of critical problems’ dislocations are provided; the problems are both convergent and related to one another, thereby redefining current research objectives and pertain to practical applications in educational praxis.

The analysis of two series of samples, using soil paste for the consistency index of 0.9 and 0.4–0.3 was carried out. The results imply that the increasing moisture content causes a decrease in the angle of shearing resistance and cohesion and is also reflected in the higher compressibility of the soil. It was observed that regardless of the soil consistency, the angle of shearing resistance decreases and the cohesion value and the oedometric modulus of primary (consolidation) and secondary compressibility grows with the increase in the clay fraction.

Colistin is being used as a last-resort drug to treat infections caused by multidrug-resistant (MDR) bacteria in humans. In veterinary medicine, colistin has been used for the treatment and prevention of infectious diseases. In the first study of mcr genes by multiplex PCR in healthy pigs from Serbia, we discovered mcr-1 in 4.85% out of 350 fecal samples. The presence of mcr-1 gene was detected on three farms located less than 100 km apart from each other, predominantly in piglet samples. The results point to the necessity of monitoring of colistin resistance and the mcr genes in food producing animals as well as restricting colistin usage on farms.

Antibiotic resistance has become a global public health concern in the last few years. Given the widespread rate of recurrence, increasing attention is being turned toward environmental pathways that potentially contribute to antibiotic resistance genes (ARGs) dissemination outside the clinical realm. In this study, a metagenome analysis of intestinal virus-like particle fraction (VLPs) from a wild coyote (Canis latrans) revealed for the first time, multiple ARGs, such as B-lactamases and multidrug efflux pumps. Description of ARGs presence in natural environments is critical to understand the emergence of resistant strains.

The resistance is understood as an expression of rebellion against the rejection and may be manifested in the form of aggression, hostility or internal dissension. This article concerns four styles of resistance: transformative, accommodative, passive and aggressive which are differentiated by the power of involvement in resistance and prisoners’ behavior towards penal institution. Resistance to isolation in prison is thus recorded a response to the situation of imprisonment, which is perceived by prisoners as imposed by the unjust restriction. It is bound by the prisoners do not accept coercion and lack of leeway and a sense that the prison staff is trying to dominate them. The research was conducted using the method of test questionnaires were 413 prisoners, prison inmates in two prisons closed type. The study, presented as a ratio analysis can be a starting point for further and extended to the whole country research on the motivation of prisoners to participate in rehabilitation programs implemented by the prison service in Poland.

Opis:

The article addresses the issue of the informal teacher culture that functions alongside the formal one in which the teacher is seen as a representative of the dominant culture. It discusses three main types of teacher resistance culture: the ruler, the super(wo)man, and the ignoramus. They show the ways in which teachers function at school that are different from the commonly accepted ones. These cultures have been distinguished on the basis of a literature analysis and author’s own research and do not constitute an exhaustive catalogue. However, being aware of them allows us to enrich pedagogical reflection on the issue of resistance in education.

Opis:

W pracy przedstawiono nową klasę mostkowych układów pomiarowych prądu stałego. Układy te mają właściwości charakterystyczne dla mostków zrównoważonych ( m. in. wartości chwilowe napięcia na przekątnej pomiarowej są równe 0). Sygnał wyjściowy w postaci cyfrowej (częstotliwość lub liczba impulsów) uzyskuje się bez zastosowania dodatkowego przetwornika analogowo-cyfrowego. Ze względu na sposób równoważenia, nazwano je mostkami równoważonymi ładunkowo. Wykazano zgodność omawianego układu z definicją mostkowego układu pomiarowego Karandiejewa. Analiza i opis mostków równoważonych ładunkowo wymagały wprowadzenia nowych pojęć, ponieważ pojęcia stosowane w opisie mostków klasycznych okazały się niewystarczające. Przy użyciu nowych pojęć uogólniono definicję pomiarów mostkowych podaną dla mostka Wheastone'a. Uogólniona definicja uwzględnia specyfikę równoważenia ładunkowego mostków rezystancyjnych, ale nadal obowiązuje dla mostka (prądu stałego) Wheastone'a.
New class of resistance measurement circuits is presented in the paper. The circuits can be regarded as DC bridges, because they have all features of classical balanced resistance bridge (among others zero voltage value across the diagonal of the bridge). Additionally digital output signal (frequency or pulse number) is accessible, without use of the ADC. For the new circuit the name "charge balanced bridge" there is proposed. In the paper there is shown the conformity of the new circuit with the classic definition of the DC bridge circuit, given e.g. by Karandeev. New terms are introduced for the analysis and description of charge balanced bridges, and the definition of bridge measurement was generalized. The new definition includes the classic Wheatstone bridge, as well as charge balanced bridges.

Opis:

The multixenobiotic/multidrug resistance (MXR/MDR) system controls transport of foreign molecules across the plasma membrane as a preventive measure before toxicity becomes apparent. The system consists of an efflux pump, ABCB1, and/or a member of the ABCC family. Ionic liquids are broadly used solvents with several unique properties such as wide liquid range, negligible vapor pressure, good thermal and chemical stability and extraordinary dissolution properties for organic and inorganic compounds. Ionic liquids containing imidazolium ring are frequently used as solvents in drug synthesis. Constitutive and induced amounts of ABCB1 and ABCC1 proteins were estimated here by Western blotting and quantified by flow cytometry in HeLa cells exposed to three homologous 1-alkyl-3-methylimidazolium and one benzyl ring substituted salts. Aliphatic substituents in position 1 of the salts caused a weak toxicity but 1-benzyl ring was strongly toxic. An 8-day long treatment with 10-4 M 1-hexyl-3-methylimidazolium chloride resulted in an about 1.5-fold increase of ABCB1 level and over 2-fold increase of ABCC1 level. The amounts of both investigated ABC-proteins were linearly dependent on the length of the imidazolium ring side chain. Such distinctive changes of the amount of MXR/MDR proteins measured in cultured cells may be a useful marker when screening for potential toxicity of various chemicals.

A car movement by constant speed on horizontal plane was realised for comparison. The vehicle engine must overcome only mechanical transmission losses, air resistance and rolling resistance, too. The air resistance size depends on the speed, the vehicle frontal area and the air resistance coefficient. It was chosen vehicles with approximated equal weight and approximated equal vehicle frontal area for comparison. These conditions fulfil vehicles Škoda 105 L, made in 1983, and Toyota Yaris 10,0 VVTi, made in 2003

Opis:

The cotton aphid, Aphis gossypii is an economically significant insect pest infesting various important crops and vegetables. The neonicotinoid, acetamiprid was recommended against aphids with excellent results. Resistance emergence and environmental pollution makes acetamiprid a favorable alternative to conventional insecticides. The aims of the present work were to predict acetamiprid resistance risk in A. gossypii, investigate cross resistance to other tested insecticides and explore acetamiprid stability in the absence of selection. A field-collected population from Sharqia governorate, Egypt was selected with acetamiprid. After 16 generations of selection, there was a 22.55-fold increase in LC50 and the realized heritability (h2) of resistance was 0.17. Projected rates of resistance indicated that, ifh2 = 0.17 and 50% of the population was killed at each generation, then a tenfold increase in LC50 would be expected in 12.2 generations. If h2 was 0.27 then 7.63 generations would be needed to achieve the same level. In contrast, with h2 of 0.07 it necessitates about 30 generations of selection to reach the same level. Cross resistance studies exhibited that the selected strain showed obvious cross resistance to the other tested neonicotinoid members, moderate cross resistance to alpha-cypermethrin and no cross resistance to pymetrozine. Fortunately, resistance to acetamiprid in the cotton aphid was unstable and resistance reverses the nearby susceptible strain throughout five generations without exposure to acetamiprid. Our results exhibited cotton aphid potential to develop resistance to acetamiprid under continuous selection pressure. The instability of acetamiprid makes A. gossypii amenable to resistance management tactics such as rotation with pymetrozine.

Opis:

At SCRI, wild species and clones of Solanum tuberosum are assessed for resistance to late blight in order to study the genetics and breed for resistance. Glasshouse progeny tests for foliage and tuber blight resistance, using true seedlings, are described. These enable the rapid screening of accessions of wild species, and the selection of the most resistant progenies in a breeding programme within one year of crossing. Assessment of the foliage resistance of clones is carried out in glasshouse tests of whole plants in flower-bud, and field trials using infector plants inoculated in the glasshouse with a complex race of Phytophthora infestans. The glasshouse test provides a reliable method of identifying R-genes and the virulence characteristics of blight isolates. The field trial gives the best estimate of field resistance and is being used to develop marker-assisted selection. Both tests are used to study the inheritance of resistance, to locate quantitative trait loci (QTL) and R-genes, and to select the most resistant clones. The tuber resistance of clones is assessed by spray-inoculating whole, immature, field-grown tubers on the day of harvest. However when large numbers of clones are involved, e.g. in the location of QTL, this is impractical, so glasshouse-grown tubers are dip-inoculated.

Opis:

Selected problems connected with operation of catalytic reactors are presented. Conversion rate of harmful substances is the principal parameter of catalyst work in respect of ecology. However, resistance of exhaust gas flow through the catalytic converter is also essential problem, apart from its chemical efficiency because fitting the catalyst in exhaust system alters flow characteristic of this system significantly. Catalytic converter can be treated as local or linear resistance element of exhaust system. The first model, in which flow resistance generated by a catalyst is treated as local resistance, is more simplified. Resistance number of the converter was calculated using Darcy model. In the second case, exhaust gas flow resistance through catalyst is treated as linear resistance with energy dissipation (linear frictional resistance) distributed linearly along way of exhaust gas flow. Friction number for the tested converter was calculated and analysed. The problem has been illustrated by results of experimental researches of three-way catalytic converter installed in exhaust system of spark ignition engine and its basic analysis.

Opis:

Computational analyses were performed to optimize the furnace throughput, steel shell and lining thickness of a blast furnace. The computations were done for measured parameters within the hearth region as this is the vital zone of the furnace with high temperature fluctuations, molten iron, and slag production. The lining materials were namely 62% high alumina (A), carbon composite (B), silicon carbide (C) and graphite bricks (D) with thermal conductivities 2, 12, 120 and 135 W/(m∙K), respectively. It was observed that by varying the refractory lining thickness from 0.2–0.35 m, and furnace inside temperatures from 1873–2073 K, certain optimal conditions could be specified for the furnace under consideration. Silicon carbide and graphite brick linings which have higher thermal conductivities, melting points, good chemical and mechanical wear resistance were observed to be the best hearth lining materials. Due to the high thermal conductivities of these two materials, the hot face temperature levels of the lining materials would be lowered. Amongst the four lining materials employed, silicon carbide and graphite bricks when used with lining cooling systems could optimize the blast furnace for better performance, production, and longer campaigns.

The paper presents the results of the properties of flame sprayed ceramic coatings using oxide ceramic materials coating of a powdered aluininiuni oxide (Al₂O₃) matrix with 3% titanium oxide (TiO₂) applied to unalloyed S235JR grade structural steel. A primer consisting of a metallic Ni-Al-Mo based powder has been applied to plates with dimensions of 5X200X300 mm and front surfaces of ø40x50 mm cylinders. Flame spraying of primer coating was made using a RotoTec 80 torch, and an external coating was made with a CastoDyn DS 8000 torch. Evaluation of the coating properties was conducted using metallographic testing, phase composition research, measurement of microhardness, substrate coating adhesion (acc. to EN 582:1996 standard), erosion wear resistance (acc. to ASTM G76-95 standard), and abrasive wear resistance (acc. to ASTM G65 standard) and thermal impact. The testing performed has demonstrated that flame spraying with 97% Al₂O₃ powder containing 3% TiO₂ performed in a range of parameters allows for obtaining high-quality ceramic coatings with thickness up to ca. 500 μni on a steel base. Spray coating possesses a structure consisting mainly of aluminium oxide and a small amount of NiAl₁₀O₁₆ and NiAl₃₂O₄₉ phases. The bonding primer coat sprayed with the Ni-Al-Mo powder to the steel substrate and external coating sprayed with the 97%Al₂O₃ powder with 3% TiO₂ addition demonstrates mechanical bonding characteristics. The coating is characterized by a high adhesion to the base amounting to 6.5 MPa. Average hardness of the external coating is ca. 780 HV. The obtained coatings are characterized by high erosion and abrasive wear resistance and the resistance to effects of cyclic thermal shock.

Opis:

Introduction and aim. The obesity is one of the greatest public health problems in developing countries and it is a triggering factor for diabetes associated with insulin resistance. The importance of cell membrane lipids as essential regulators of insulin resistance, since changes in the dynamic properties of the cell membrane (e.g., membrane fluidity), could be one of the events by which obesity affects insulin sensitivity. Thus, the insulin resistance may not only be a cause but also a consequence of lipid disorders such as dyslipidemia and/or cell membrane phospholipid composition change. The modification of plasma membrane lipid composition can change membrane biophysical properties and thus influencing protein-lipid interactions, enzymatic activity and regulation of surface receptors. Alterations in the lipid composition modify the fluidity of plasma membranes and the expression of membrane functions, such as receptor binding and enzyme activities. This review summarizes the current knowledge on the effects of the modulation of plasma membrane lipid composition and membrane fluidity in the functionality of membrane proteins involved in insulin activity, including the insulin receptor, glucose transport and Na+/K+ ATPase and, in turn, the key features of the metabolic syndrome. Material and methods. References for that article were found through PubMed and Google Scholar, using terms: “obesity”, “insulin resistance” and “membrane properties”. The research was limited to abstracts and available full-text articles. Analysis of the literature. There is a strong relationship between dietary lipids, membrane lipid profiles and insulin resistance. The changes in the dynamic properties of the cell membrane (e.g., membrane fluidity), could be one of the events by which obesity affects insulin sensitivity. The modification of plasma membrane lipid composition can change membrane biophysical properties and thus influencing protein–lipid interactions, enzymatic activity, and regulation of surface receptors. Modifications of membrane phospholipid composition could have a role in the insulin action by altering membrane fluidity and, as a consequence, the insulin signaling pathway. Conclusion. As conclusion the membrane-lipid therapy approach can be used to treat important pathologies such as obesity and many others diseases such as : cancer, cardiovascular pathologies, neurodegenerative processes, obesity, metabolic disorders, inflammation, and infectious and autoimmune diseases. This pharmacological strategy aims to regulate cell functions by influencing lipid organization and membrane fluidity, inducing a concomitant modulation of membrane protein localization and activity which might serve to reverse the pathological state. Through this review we suggest an in-depth analysis of the membrane lipid therapy field, especially its molecular bases and its relevance to the development of innovative therapeutic approaches.

Introduction. In the atmospheric air, fungal spores of the genus Fusarium are present which may be resistant to antifungal drugs used in medicine. The aim of this study was to determine the sensitivity to selected antimycotics, and to identify the MIC (minimum inhibitory concentration) for strains belonging to the species F. culmorum. Material and methods. Fungal strains were isolated from atmospheric air sampling in the vicinity of fields where winter wheat was cultivated. Evaluation of susceptibility to antifungal drugs was carried out using E-test strips. Results. All isolates were characterized by resistance to ketoconazole, itraconazole and fluconazole. MIC for amphotericin B was 0.023 µg · cm–3, for voriconazole 0.016 µg·cm–3, for posaconazole 0.006 µg·cm–3 and for caspofungin 0.25 µg·cm–3. Among the isolates tested, 8 were resistant to voriconazole, 3 resistant to posaconazole and 10 resistant to amphotericin B. Conclusions. The examined strains presented different sensitivity to antifungal drugs. The strongest fungicidal activity was found in the case of: posaconazole, voriconazole and amphotericin B. In the atmospheric air there may exist strains of F. culmorum which have natural resistance to some antimycotics.
Wstęp. W powietrzu atmosferycznym obecne są zarodniki grzybów z rodzaju Fusarium, mogące posiadać oporność na stosowane w medycynie leki przeciwgrzybicze. Celem pracy było określenie wrażliwości na wybrane antymikotyki oraz wyznaczenie MIC (minimalnego stężenia hamującego) dla szczepów należących do gatunku F. culmorum. Materiał i metody. Szczepy grzybów wyizolowano z powietrza atmosferycznego pobranego w sąsiedztwie pól na których uprawiano pszenicę ozimą. Ocenę wrażliwości na leki przeciwgrzybicze przeprowadzono z zastosowaniem pasków E-test. Wyniki. Wszystkie izolaty odznaczały się opornością w stosunku do ketokonazolu, itrakonazolu i flukonazolu. MIC dla: amfoterycyny B wynosiło 0,023 µg· cm–3, dla worykonazolu 0,016 µg· cm–3, dla pozakonazolu 0,006 µg·cm–3 oraz dla kaspofunginy 0,25 µg·cm–3. Wśród badanych izolatów było 8 opornych na worykonazol, 3 oporne na pozakonazol i 10 opornych na amfoterycynę B. Wnioski. Badane grzyby były w różnym stopniu wrażliwe na testowane antymikotyki. Najsilniejsze działanie grzybobójcze stwierdzono w przypadku: pozakonazolu, worykonazolu i amfoterycyny B. W powietrzu atmosferycznym obecne są szczepy z gatunku F. culmorum posiadające naturalną oporność na niektóre antymikotyki.

Opis:

Glufosfamide (β-D-glucosyl-ifosfamide mustard) is a new agent for cancer chemotherapy. Its pharmacology is similar to commonly used oxazaphosphorines, but it does not require activation by hepatic cytochrome P-450 and preclinically demonstrates lower nephrotoxicity and myelosuppression than ifosfamide. The aim of the study was a comparison of the drug resistance profiles of glufosfamide and other oxazaphosphorines in childhood acute leukemias. Leukemic cells, taken from children with ALL on diagnosis (n = 41), ALL on relapse (n = 12) and AML on diagnosis (n= 13) were analyzed by means of the MTT assay. The following drugs were tested: glufosfamide (GLU), 4-HOO-ifosfamide (IFO), 4-HOO-cyclophosphamide (CYC) and mafosfamide cyclohexylamine salt (MAF). In the group of initial ALL samples median cytotoxicity values for GLU, IFO, CYC and MAF were 15.5, 33.8, 15.7 and 7.8 μM, respectively. In comparison with initial ALL samples, the relative resistance for GLU and IFO in relapsed ALL samples was 1.9 (p = 0.049) and 1.3 (ns), and in initial AML samples 31 (p < 0.001) and 5 (p = 0.001), respectively. All oxazaphosphorines presented highly significant cross-resistance. Glufosfamide presented high activity against lymphoblasts both on diagnosis and on relapse.
