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.
