Opis:

The paper concerns steel domes with regard to the special structures named tensegrity. Tensegrities are characterized by the occurrence of self-stress states. Some of them are also characterized by the presence of infinitesimal mechanisms. The aim of this paper is to prove that only tensegrity domes with mechanisms are sensitive to the change of the level of initial prestress. Two tensegrity domes are considered. In addition, a standard single-layer dome is taken into account for comparison. The analysis is carried out in two stages. Firstly, the presence of the characteristic tensegrity features is examined (qualitative analysis). Next, the behavior under static external loads is studied (quantitative analysis). In particular, the influence of the initial prestress level on displacements, effort, and stiffness of the structure is analyzed. To evaluate this behavior, a geometrically non-linear model is used. The model is implemented in an original program written in the Mathematica environment. The analysis demonstrates that for a dome with mechanisms, the adjustment of pre-stressing forces influences the static properties. It has been found that the stiffness depends not only on the geometry and properties of the material but also on the initial prestress level and external load. In the case of the non-existence of mechanisms, structures are insensitive to the initial prestress level.

Opis:

The paper presents the results of research into the pigment composition of seawater samples taken from various depths in the Gulf of Gdańsk in April and September 1999. Pigments were separated by RP–HPLC, and identification was confirmed by co-injection with reference standards and on-line diode array spectra. The following groups of pigments were identified: chlorophylls: a, b, c1 + c2; photosynthetic carotenoids (PSC) – peridinin, fucoxanthin, α-carotene; photoprotecting carotenoids (PPC) – diadinoxanthin, alloxanthin, zeaxanthin, lutein, neoxanthin, violaxanthin and β-carotene. Quantitative and qualitative diversity in pigment characteristics were observed in both seasons, though lutein and α-carotene were not identified in the September samples. The respective April and September concentrations of the functional groups of pigments were: total chlorophylls content 0.47–104.25 and 0.57–13.66 μg dm−3; PSC 0.07–21.23 and 0.02–1.56 μg dm−3; PPC 0.05–14.08 and 0.04–1.79 μg dm−3. Within the PSC group, peridinin and fucoxanthin were dominant in the April samples, but only fucoxanthin in the September ones. Among the PPCs, diadinoxanthin and alloxanthin were dominant in April, zeaxanthin in September. Photosynthetic and photoprotecting carotenoids display a linear correlation with chlorophyll a content in all the samples.

Opis:

The existing literature, including records of both fossil and extant echinoid encrustation, is quantitatively analysed and reviewed. This shows that echinoid encrustation (number of encrusted echinoid taphocoenoses) has increased nearly continuously and dramatically to the present day, as confirmed by linear regression values of more than 85 per cent. It also demonstrates that current levels of echinoid fouling stabilised by the Miocene, while there has been a more or less continuous record of echinoid encrustation since the Late Cretaceous. Several increases have been identified since echinoid encrustation first noted occurrence from the Late Carboniferous. This trend is explained as the probable result of corresponding increases in productivity (richness, biomass, energetics, ecospace utilisation) and resources in the marine environment, including epibionts and their hosts. This conclusion matches other indicators, including the number and thickness of shell beds, bioerosion and predation intensity or biodiversity. The trajectory might have been altered to some degree by biases (e.g. selective recording, sampling effort, outcrop area, rock volume) in the same way as palaeobiodiversity estimates. Two recognised long-term gaps in echinoid encrustation (Upper Ordovician–Lower Carboniferous and Permian–Lower Cretaceous) are explained in part as bias and as biological and taphonomic signals. These gaps are caused mostly by the rapid disarticulation of Palaeozoic-type echinoids, the methodology applied here, and a lack of interest in the encrustation of Jurassic echinoids. Conversely, three short-term gaps in the Cenozoic are interpreted exclusively as bias. If correct, the present study demonstrates quantitatively the step-wise increase of productivity through time. It also suggests potential focus on further study, including the collection of new data from the field and pre-existing collections, as best for other encrustation proxies (e.g., percent of coverage by epibionts, ratio of encrusted to nonencrusted shells, taxa richness or numerical abundance of sclerobionts) in cases of large-scale analyses.

Opis:

The paper aims at recognizing the possibilities and perspectives of application of qualitativequantitative research methodology in the field of economics, with a special focus on production engineering management processes. The main goal of the research is to define the methods that would extend the research apparatus of economists and managers by tools that allow the inclusion of qualitative determinants into quantitative analysis. Such approach is justified by qualitative character of many determinants of economic occurrences. At the same time quantitative approach seems to be predominant in production engineering management, although methods of transposition of qualitative decision criteria can be found in literature. Nevertheless, international economics and management could profit from a mixed methodology, incorporating both types of determinants into joint decision-making models. The research methodology consists of literature review and own analysis of applicability of mixed qualitative-quantitative methods for managerial decision-making. The expected outcome of the research is to find which methods should be applied to include qualitativequantitative analysis into multicriteria decision-making models in the fields of economics, with a special regard to production engineering management.

Opis:

Lean has established itself as the primordial approach to obtain operational excellence. Its simple and intuitive techniques focus on reducing lead time through continuous improvement, involving all levels of employees in the organization. However, the rate of successful implementations has remained low. This paper contributes to the understanding of continuous improvement in a Lean context, by analyzing a database of almost 10.000 improvement actions, from 85 companies, covering the time frame 2010–2018. It discusses categories of actions, their impact and cost, as well as key characteristics of the companies. It proposes an objective criterion to identify “success” and “failure” in Lean implementation and tries to link these to operational results. It is probably the first time an analysis of this magnitude on the subject has been performed.

Opis:

Internet auction sites are trading platforms with huge number of visitors who may become customers. On-line auctions allow users to buy and sell products without geographical borders, as in majority of cases ordered products are delivered by surface mail. The aim of the study was to collect substantial amount of data describing on-line auctions in a variety of attributes, and customer behaviour. We provide quantitative arguments in the discussion on effectiveness of promotional features used in on-line auctions. Experimental survey showed that almost 2/3 of the total number of observed auctions were indexed in five top (out of 23) product categories. Noticeable difference in sale effectiveness was observed for particular days of week and hours of auction termination. On Saturdays and Sundays the chance to terminate an auction with transaction was 17.72% and 19.46%, respectively, while on Tuesdays – Orly 14.29%. The highest ratio of successful auction-transaction against total number of auctions ending within particular hour occurred between 19:00 and 22:00. Our approximation of job lot transactions showed that it was a common practice among bidders to buy more than one product form one seller. In the reference period about 25% of all transactions could be qualified as job-lot ones. A miniature image displayed by auction title appeared the cheapest and most price effective form of advertising an auction while promoting on action site main page was the most effective in increasing visits/displays (by 2341%), yet, the high price of this advertising feature may pay back only if customers’ visits turn into transactions.

Internal logistics is a key element of a production process as it specifies product quality, timeliness and value of orders. The purpose of the research was to determine the amount of non-compliance in the selected production process caused by internal logistics operations. The analysis covers both the quantity and type of non-compliance as well as the cost of non-compliance. One of the basic quality management tools was used in the research - Parteo-Lorenz analysis. An attempt was made to identify potential causes of non-compliance. The significant impact of non-compliance arising in internal logistics operations in production costs was pointed out.

A quantitative analysis of spatio-temporal diagrams, which describe the dynamics of a chosen, spatially extended dynamic system (a domain wall in a thin magnetic garnet film) is presented. Two quantifiers characterizing such diagrams - a correlation function and power spectrum density function - were calculated using solutions of equations of motion. It was found that introducing these quantifiers to the analysis of spatio-temporal diagrams enables one to effectively characterize the type and the properties of motion of the considered system.

The article deals with the research on the quantitative classification of land use, which directly affects the amount of land use data collected in the real estate cadastre. For the purpose of this article, the cadastral systems of seven European countries – Austria, Bulgaria, Estonia, Spain, Lithuania, Germany and Poland – have been examined, taking into account how detailed is the classification in agricultural and forest areas. The research covered the provisions of legal acts applicable in the researched seven European countries and made available in national languages by the government bodies. The article asks the following three questions: 1) whether the researched countries adopted the same approach to isolating classes of items related to agricultural and forest areas; 2) whether the researched countries feature the same number of classes of items recorded at various levels of detail; 3) what is the percentage of the distinguished item classes of land uses in the agricultural and forest areas in relation to all of the distinguished item classes at all the levels of detail. The conducted research can be used as a material supporting works consisting of the modernization of the functioning of land registration in the real estate cadastre in Poland.

Background: The aim of the research was to acquire knowledge as to how the development of scientific publications looks, while also to specify the scope of research on the area of ski tourism. The research process is concentrated on the following research questions: In what way has the scientific output developed in the field of research on ski tourism? Who is the principal participant (countries, universities, authors, titles of sources) in the accumulation of research in a particular field? Method: In the process of selecting the test sample as a source of bibliometric data the Scopus database was applied. The test sample (N=1500) consisted of publications that contained such phrases in their works as “ski tourism”, “ski hotels”, “ski resorts” in their titles or key words. A general profiling of publications was conducted in order to assess the trends in scientific output and the acknowledgement of the leading co-workers in the field of research. MS Excel was applied for the purpose of supporting the process of analysis and the visualization of results. Results: The analysis indicates that research on ski tourism is one of the aspects of great tradition. This has gained increasingly great interest among academic environments, which led to the breakthrough growth in the number of publications in 2006 indexed in the Scopus database. This publication output encompasses 26 research areas. Conclusions: The principal areas yielding the largest number of publications with regard to ski tourism are to be found in social sciences and science on the environment. The main authors and co-authors in this field are as follows: representatives from the EU and the USA, while the most productive research institution is Universität Innsbruck. The author of the greatest number of publications is Prof. Daniel Scott (University of Waterloo, Canada). The EU is one of the main sponsors.

Opis:

Alicyclobacillus sp. are acidothermophilic bacteria frequently contaminating fruit based products (juices and juice concentrates). These sporulating bacteria are able to survive at elevated temperatures and highly acidic environments which causes difficulties in their removal from industrial environments. Although numerous literature data examine Alicyclobacillus sp. presence in fruit based products and methods of their elimination, there is still a limited knowledge on ability of these bacteria to adhere to abiotic surfaces. Therefore, the objective of this study was to determine Alicyclobacillus sp. cells' hydrophobicity and capability of biofilm formation on a glass surface. The degree of cells hydrophobicity, according to Microbial Adhesion to Hydrocarbon (MATH) and Salt Aggregation Test (SAT), was investigated for eleven environmental isolates from natural Polish habitats, identified as Alicyclobacillus sp., and a Alicyclobacillus acidoterrestris DSM 3922 reference strain. The dynamics of biofilm formation within 3-day incubation on a glass surface was evaluated and quantified by a plate count method both, for cultures with and without agitation. All of the bacterial strains tested expressed ability to colonize a glass surface and four environmental isolates were classified as fast-adherent strains. The mature biofilm structures were predominantly formed after 48 hours of incubation. Dynamic culturing conditions were observed to accelerate the biofilm formation. The majority of strains expressed a moderate hydrophobicity level both, in SAT (41.7%) and MATH-PBS (75.0%), as well as MATH-PUM (91.7%) tests. However, no correlation between hydrophobicity and cell adherence to a glass slide surface was observed.

Opis:

Online quantitative analysis of reaction gases or exhaust in industrial production is of great significance to improve the production capacity and process. A novel method is developed for the online quantitative analysis of reaction gases or exhaust using quantitative mathematical models combined with the linear regression algorithm of machine learning. After accurately estimating the component gases and their contents in the reaction gases or exhaust, a ratio matrix is constructed to separate the relevant overlapping peaks. The ratio and calibration standard gases are detected, filtered, normalized, and linearly regressed with an online process mass spectrometer to correct the ratio matrices and obtain the relative sensitivity matrices. A quantitative mathematical model can be established to obtain the content of each component of the reaction gases or exhaust in real time. The maximum quantification error and relative standard deviation of the method are within 0.3% and 1%, after online quantification of the representative yeast fermenter tail gas.

Opis:

Pre-processing provides an effective way for fly ash's high value-added utilization. However, the shortcomings of pre-processing methods such as grinding and flotation are apparent with many disadvantages that make it more challenging to use efficiently. Microwave heating helps the SiO2-Al.2O3 bond break, not only can make the structural change of the material can also promote the chemical reaction process. In the article, XRD, SEM, FT-IR, ammonia nitrogen adsorption, and other methods were used to analyze the changes in the properties of fly ash before and after microwave pre-treatment, the change in adsorption performance of fly ash before and after microwave treatment was analyzed. The study found that under microwave conditions of 600 W and 15 min, the adsorption rate of ammonia nitrogen by fly ash reached a maximum of 29.67%. The intensity of mullite and amorphous diffraction peaks decreased after 20 min at 600 W. The Si-O-(Si, Al) and Si-O-(Si) bonds showed significant changes at 15 min and 20 min under 600 W conditions. Based on the results, the microwave conditions were selected at 600 W for different periods, and semi-quantitative analysis was carried out by XRD-Rietveld, infrared peak fitting, and nuclear magnetic resonance. The XRD-Rietveld analysis showed that the amorphous phase content reached 46.18% at 15 min. In the infrared peak fitting, the fitting area at 1300-900 cm-1 and 600-400 cm-1 peaks at 56.92% at 25 min and 17.5% at 15 min, respectively. The silicon-oxygen network's degree of connection and polymerization was reduced after 15 min of microwave treatment for the nuclear magnetic resonance analysis. By combining specific surface area measurements, it was discovered that the maximum specific surface area attained a value of 3.122 m2/g at 15 min.

Opis:

The paper presents the results of research on the microstructure of martensitic X10CrMoVNb9-1 (P91) and X13CrMoCo- VNbNB9-2-1 (PB2) steel subject to long-term ageing at the temperature of 620°C and holding times up to 30 000 hours. The microstructural tests of the examined steel types were performed using a scanning microscope Joel JSM - 6610LV and a transmission electron microscope TITAN 80 - 300. The stability of the microstructure of the investigated steels was analyzed using a quantitative analysis of an image, including measurements of the following: the density of dislocations inside martensite/subgrain laths, the width of martensite laths, and the mean diameter of precipitates. It has been concluded that during long-term ageing, the microaddition of boron in PB2 steel significantly influenced the slowing of the process of degradation of the martensitic steel microstructure, as a result of slowing the process of coagulation of M23C6 carbides and Laves phase. It had a favorable effect on the stabilization of lath microstructure as a result of retardation of the processes of recovery and polygonization of the matrix.

Opis:

The results of investigations of three commercial binders applied in the Alphaset technology marked as: Sample E , Sample T and Sample S are presented in the hereby paper. These samples were subjected to the pyrolysis process at a temperature of 900°C (inert atmosphere, He 99.9999). The gas chromatograph coupled with the mass spectrometer and pyrolizer (Py-GC/MS) were used in the study. The identification of gases emitted during the thermal decomposition was performed on the basis of the mass spectral library. The obtained results indicate a certain diversification of emitted gases. Among the pyrolysis products the following harmful substances were identified: furfuryl alcohol, formaldehyde, phenol and also substances from the BTEX (benzene, toluene and ethylobezneze and xylenes) PAHs (Polycyclic Aromatic Hydrocarbons) and VOC groups (Volatile Organic Compounds). Therefore, from the environment protection point of view performing systematic investigations concerning the harmfulness of binders applied in the moulding and core sands technology, is essential.

Opis:

Stereological description of dispersed microstructure is not an easy task and remains the subject of continuous research. In its practical aspect, a correct stereological description of this type of structure is essential for the analysis of processes of coagulation and spheroidisation, or for studies of relationships between structure and properties. One of the most frequently used methods for an estimation of the density Nv and size distribution of particles is the Scheil - Schwartz – Saltykov method. In this article, the authors present selected methods for quantitative assessment of ductile iron microstructure, i.e. the Scheil - Schwartz – Saltykov method, which allows a quantitative description of three-dimensional sets of solids using measurements and counts performed on two-dimensional cross-sections of these sets (microsections) and quantitative description of three-dimensional sets of solids by X-ray computed microtomography, which is an interesting alternative for structural studies compared to traditional methods of microstructure imaging since, as a result, the analysis provides a three-dimensional imaging of microstructures examined.

Opis:

Exploring the stability of states and political systems is of interest to scientists and politicians all around the world. One of the most important questions in this field is the question of the relationship between stability and freedom. This paper considers the relationship between economic freedom and stability with regards to the example of countries of Central and Eastern Europe. The study uses quantitative analysis and the operationalisation of economic freedom through the Index of Economic Freedom (IEF); furthermore, stability is studied through the Fragile States Index (FSI), and the Political Stability and Absence of Violence/Terrorism Index (PSI). The analysis reveals a strong correlation between economic freedom and stability. According to linear regression models obtained by the author, economic freedom has a strong impact on stability. Models show that most of the components of IEF increase stability, whilst some components decrease it. This means that the same factors affect economic freedom and stability in different ways. In particular, taxes have a very positive effect on stability. At the same it is obvious that taxes reduce economic freedom. This fact allows us to resolve the existing contradictions among politicians and scientists, who differently assess the impact of economic freedom on stability. It may be stated that whilst economic freedom has in general a strong positive effect on stability, it can also have a negative effect.

Opis:

Heat treatment of aluminum casts is necessary for achieving the desired properties of casts. Heat treatment caused changes in microstructure and substructure of materials and therefore it is necessary to control which changes are sufficient and which are insufficient. Morphology (shape, size and distribution) of microstructural features influence the properties of cast rapidly. Contribution describes influence of the heat treatment marking T4 - solution treatment in dependence on temperature (505, 515 a 525 °C) and holding time (2, 4, 8, 16 a 32 hour) on structure (α–phase, eutectic silicon, intermetallic phases) and mechanical properties (ultimate tensile strength - UTS and Brinell hardness - HBW) of A226 cast alloy. This cast alloy is made out of secondary aluminum. Secondary aluminum alloys are made of aluminum scrap. About 70 % of such material are used in the manufacture of casts. Therefore the strictly microstructure control of experimental material before and after heat treatment is necessary for declaration of cast properties. Nowadays manufacturers use the methods of quantitative analysis for quick control of microstructural features. This work present some of them.

Opis:

Neuroblastoma, the most common extracranial solid tumour of childhood, is a malignancy of unknown origin and non-specific symptoms. One of the markers of the disease is GD2 ganglioside (disialoganglioside), which is abundantly expressed on the surface of neuroblastoma cells. Gangliosides are known to be shed by tumour cells and this phenomenon can be significant in cancer progression as they inhibit a number of immune responses both in vitro and in vivo. In search for novel markers useful in monitoring and prognosis of neuroblastoma, we developed and validated a new quantitative method of GD2 ganglioside analysis in human blood plasma. We evaluated the level of gangliosides in blood serum of 34 neuroblastoma patients using high-performance liquid chromatography. The technique was used to detect fluorescently labelled oligosaccharides derived from serum glycosphingolipids by enzymatic digestion with ceramide glycanase. The developed method allowed determination of GD2 concentrations at the picomole level and required only 40 µl of plasma, which should be particularly useful when the quantity of clinical material is limiting. Moreover, this method can be applied to study concentration of other gangliosides, as shown for GD3 ganglioside. Analysis of plasma samples from the 34 neuroblastoma patients did not reveal any correlations between the concentration of GD2 ganglioside and clinical parameters, including the results of therapy; it showed, however, that the concentration of GD2 ganglioside in the plasma of neuroblastoma patients decreased substantially in the course of treatment.

Firstly, the origin and the background of the division of music genres were shortly presented. Then, several objective parameters of an audio signal were recalled that have an easy interpretation in the context of perceptual relevance. Within the study parameter values were extracted from music excerpts, gathered and compared to determine to what extent they are similar within the songs of the same performer or samples representing the same piece.

For multi-factor analysis we will apply the method of generalizing analysis on the basis of complex variables and dimensionality theory. The methods for obtaining structural relations for various types of tasks of traffic flow conditions in the space of city streets and roads have been developed. The analysis of basic quantitative relations in time form, and also taking into account traffic stream state change under the influence of traffic density increase as a growing probability of road traffic accidents occurrence, and sluggishness at road traffic conditions, improvement has been carried out.

Opis:

The paper aims to describe the potential use of phase trajectory for damage detection of structural components. The attractor of the examined trajectory is a static equilibrium point of the element being diagnosed. Two different damage indices are proposed to evaluate the severity of damage in the diagnosed component. The first one refers to distance between a point on a trajectory and the point which is the attractor of the trajectory. The other one relates to linearity of the Poincaré map. Effectiveness of the proposed method was evaluated on: a simple model with two degrees of freedom, data from the finite element method model of a cantilever beam with a crack, and experimental data for a cracked plate. With the proposed method, the damage can be quickly and effectively detected. By comparing the current trajectory with that from the previous diagnostic test, it is possible to establish if the nature of crack is either propagating or stationary.

Purpose: The aim of the article is to show the modified method of calculating the economic potential on the example of territorial units of the Upper Silesian Metropolis. Design/methodology/approach: Economic potential is a measure of a region's strength compared to other regions. In economics, potential is a substitute for socio-economic development. The methodology of calculating the modified economic potential of territorial units was discussed in the first part of the article, and an empirical example is presented in the second part. Findings: As a result of the research, strong regions were identified and the self-potential of the regions and their surroundings were compared. Research limitations/implications: The proposed modified method of potentials can be used for a comparative analysis of any territorial units. The metric that is used to measure the distance between territorial units is important. Practical implications: On the basis of the presented method, any regions or countries can be compared in terms of socio-economic development. Social implications: The method makes it possible to compare the socio-economic development of regions in terms of income and population. Originality/value: The article compares selected communes of the Silesian Voivodeship in terms of income, population and socio-economic development. A modified measure of economic potential was used.

Azodicarbonamide (ADA) additives are limited or prohibited from being added to wheat flour by various countries because they may produce carcinogenic semicarbazide in humid and hot conditions. This study aimed to realize the non-destructive detection of ADA additives in wheat flour using high-throughput Raman imaging and establish a quantitative analysis model. Raman images of pure wheat flour, pure ADA, and wheat flour-ADA mixed samples were collected respectively, and the average Raman spectra of each sample were calculated. A partial least squares (PLS) model was established by using the linear combination spectra of pure wheat flour and pure ADA and the average Raman spectra of mixed samples. The regression coefficients of the PLS model were used to reconstruct the 3D Raman images of mixed samples into 2D grayscale images. Threshold segmentation was used to classify wheat flour pixels and ADA pixels in grayscale images, and a quantitative analysis model was established based on the number of ADA pixels. The results showed that the minimum detectable content of ADA in wheat flour was 100 mg/kg. There was a good linear relationship between the ADA content in the mixed sample and the number of pixels classified as ADA in the grayscale image in the range of 100 – 10,000 mg/kg, and the correlation coefficient was 0.9858. This study indicated that the combination of PLS regression coefficients with threshold segmentation had provided a non-destructive method for quantitative detection of ADA in Raman images of wheat flour-ADA mixed samples.

Opis:

Fourier transform infrared imaging instrumentation has come of age for the rapid acquisition of biosample IR images, and thus now allows developing analytical methods based upon the molecular information of samples contents. For the biomedicine field, Fourier transform infrared imaging should be able to play a role in the molecular characterization of cells and tissues where no other analytical method provides quantitative information. Now, a compromise may be obtained between an acceptable acquisition time of IR images, which should never exceed a few tens of minutes, and the necessary spatial resolution (down to the diffraction limit, although limited for biology), spectral resolution (2 to 8 $cm^{-1}$ for biosample analyses), and signal-to-noise ratio level, to provide a diagnostic answer to clinicians during the surgery time. Here, we will discuss the potential of Fourier transform infrared imaging in face to major pathologies (myopathies, brain tumors, metabolic diseases) for which current imaging methods remain unable to provide sufficient information for a precise diagnosis. Quantitative molecular information may be extracted from infrared images of samples as soon as samples volume/thickness is controlled as well as absorption and absorptivity of the molecules to analyze may be isolated from other absorbing compounds. In this context, metabolic parameters appear as the main targets for providing critical information about the physiological status of a biosample due to their characteristic infrared spectra. As examples, it will be shown how to isolate and quantify glucose, lactic-acid, urea, etc. absorptions from complex biosample infrared images.

Introduction. Functional food plays an important role in the prevention, management and treatment of chronic diseases. One of the most interesting techniques of functional food production is extrusion-cooking. Functional foods may include such items as puffed cereals, breads and beverages that are fortified with vitamins, some nutraceuticals and herbs. Due to its pharmacological activity, chamomile flowers are the most popular components added to functional food. Objective. Quantitative analysis of polyphenolic antioxidants, as well as comparison of various methods for the extraction of phenolic compounds from corn puffed cereals, puffed cereals with an addition of chamomile (3, 5, 10 and 20%) and from Chamomillae anthodium. Materials and Methods. Two modern extraction methods – ultrasound assisted extraction (UAE) at 40 °C and 60 °C, as well as accelerated solvent extraction (ASE) at 100 °C and 120 °C were used for the isolation of polyphenols from functional food. Analysis of flavonoids and phenolic acids was carried out using reversed-phase high-performance liquid chromatography and electrospray ionization mass spectrometry (LC-ESI-MS/MS). Results and Conclusions. For most of the analyzed compounds, the highest yields were obtained by ultrasound assisted extraction. The highest temperature during the ultrasonification process (60 °C) increased the efficiency of extraction, without degradation of polyphenols. UAE easily arrives at extraction equilibrium and therefore permits shorter periods of time, reducing the energy input. Furthermore, UAE meets the requirements of ‘Green Chemistry’.

Opis:

Safety in aviation has various connotations. According to the International Civil Aviation Organization (ICAO), it is a state in which the possibility of harm to people and property is minimised and maintained within a continuous process of identifying threats and managing safety risks at an acceptable level or below an acceptable level. Actions related to threat identification can be reactive, proactive, or predictive. Reactive actions aim to verify what happened, why, and how to prevent it from recurring. For this purpose, incidents that occurred in the past are analysed. By Polish law, the Commission for Investigating Aviation Accidents investigates accidents and serious incidents, while incidents mostly fall under the responsibility of the aviation organisation in which the incident occurred. Therefore, this article aims to identify threats causing incidents. Three thousand two hundred aviation incidents reported between 2017 and 2022 to the Civil Aviation Office as part of the mandatory and voluntary event reporting system were analysed. The identified causes, due to the diversity of their description, were divided into four groups. The first group consists of human factors, representing inadequate actions by pilots, crews, or individuals who caused a situation of danger. The second group comprises errors in the operation of technical objects, including aircraft. This group also includes situations where foreign objects violate airspace or minimum conditions are breached. The next group includes environmental causes such as wild animals, birds, and weather conditions. The last group consists of procedures related to flight phases.

Opis:

A computer program was developed for studying transferred nuclear Overhauser effects in complex spin systems. It permits quantitative analysis of nuclear Overhauser effects observed in biologically important systems, such as ligands interacting with transmembrane receptors in the presence of lipid bilayers. The full generalized relaxation matrix approach takes into account the local mobility, spin equivalence, finite exchange rates, and spectral overlap. The program can be used either to simulate theoretical nuclear Overhauser effect buildup curves or to fit a relaxation matrix of a given model to experimental data. Selected examples illustrate the program's performance.

Opis:

Difficulty of sailing is quite subjective matter. It depends on various factors. Using Marine Traffic Simulation System (MTSS) developed by Osaka University this challenging subject is discussed. In this system realistic traffic flow including collision avoidance manoeuvres can be reproduced in a given area. Simulation is done for southward of Tokyo Bay, Strait of Singapore and off‐Shanghai area changing traffic volume from 5 or 50 to 150 or 200% of the present volume. As a result, strong proportional relation between near‐miss ratio and traffic density per hour per sailed area is found, independent on traffic volume, area size and configuration. The quantitative evaluation index of the difficulty of sailing, here called risk rate of the area is defined using thus defined traffic density and near‐miss ratio.

Opis:

α-CL-20 polymorphic impurity in ε-CL-20 studies have been carried out using Dispersive Raman Spectroscopy. ε-, β-, α- and γ-CL-20 polymorphs were produced using crystallization methods with sample recovery from the solution being >90%, and chemical purity of about 99%. The polymorphs prepared were characterized using Dispersive Raman Spectroscopy over the Raman shift region of 100-3500 cm-1 using a 514 nm argon ion laser. The experimental studies were supported by ab initio computations performed at B3LYP level using a 6-31+G** basis set. The computed vibrational frequencies of the CL-20 conformers correspond to the ε, β and α or γ-CL-20 polymorphs when compared with the observed frequencies. α-CL-20 shows a distinct feature at 280 cm-1 as compared with those of the ε-CL-20 polymorph. Using Dispersive Raman Spectroscopy, a linear relationship was demonstrated for the absolute peak height and absolute peak area ratio of α-CL-20 versus the weight percent of α-CL-20. This method enables a detection limit of this polymorphic impurity down to 2 wt%.

Opis:

Zidentyfikowano ponad 40 elementów wpływających na proces kreowania zaufania w handlu elektronicznym, które zostały zaklasyfikowane do siedmiu obszarów kreowania zaufania: komunikacja z klientem, dokonywanie płatności, dostarczanie towaru, obsługa posprzedażna, ochrona prywatności, transfer zaufania zewnętrznego, inne elementy. Zaproponowano metodę ilościową, bazującą na wielowymiarowej analizie porównawczej, która umożliwiła porównanie poziomu kreowania zaufania przez poszczególne sklepy internetowe. Metoda została wykorzystana do analizy 30 polskich sklepów. Autor wprowadził wskaźniki poziomu kreowania zaufania, bazujące na stopniu wykorzystania elementów kreowania zaufania przez sklepy w poszczególnych obszarach. Przeprowadzono analizę korelacji pomiędzy wskaźnikami poziomu kreowania zaufania i wskaźnikami opisującymi skłonność klientów do dokonywania zakupów. Analiza ta umożliwiła zbadanie wpływu kreowania zaufania w poszczególnych obszarach na pozyskiwanie klientów. Badania pokazały, że brak dbałości ze strony sklepów działających w sieci o formy komunikacji z klientem, ochronę prywatności użytkowników, transfer zaufania zewnętrznego oraz wygodę i bezpieczeństwo dokonywania płatności mają negatywny wpływ na zaufanie klientów do dokonywania zakupów za pośrednictwem Internetu.
More than 40 elements which play significant role in trust building were identified. They may be considered as belonging to one of the distinguished areas: communication with customers, payment process, shipment of goods, post-sale service, customer's privacy, external trust transfer, or other. The author has developed a quantitative method based on the multi-parameter comparative analysis which enabled certain comparison of trust building in different shops. The method was applied in the analysis of 30 Polish shops. The author has introduced trust indicators, based on the use of different trust elements in Web Shops and determined the level of trust for each shop on every particular area. Subject to the analysis were correlations between trust indicators which describe trust level in appropriate areas, as well as the indicators defining customers' tendency to shop. The analysis enabled examination of the influence of trust building in different areas on customer encouragement. Major conclusion is that the lack of appropriate communication with customers, appropriate care for personal data and external trust transfer, along with carelessness concerning the comfort and security of payment, definitely has negative influence on customers' trust to do shopping via the Internet.

Opis:

The Polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate (SDS-PAGE) has been used for qualitative and quantitative analyses of milk proteins. Electrophoretically pure casein fractions and whey proteins were used as standards. The binding of Coomassie brilliant blue R-250 by the particular proteins was found to differ. The dye-absorption coefficients calculated to correct the errors of densitometric measurements for αs1-, αs2-, ß-, and k- casein dye complexes were as follows: 1.00; 1.00; 1.07; 0.59, and 1.00; 0.67; 1.34 for α-lactalbumin, ß-lactoglobulin and bovine serum albumin, respectively. The procedure described for the elimination of dye-absorption errors seems more universal and simple for protein quantitation.
Białka mleka, zarówno frakcje kazeinowe jak i białka serwatkowe występują w określonych stosunkach ilościowych. Najczęściej stosowaną i uniwersalną, ze względu na łatwość, szybkość, niski koszt, a zarazem dokładność, metodą charakteryzującą zależności ilościowe pomiędzy wymienionymi powyżej białkami mleka jest elektroforetyczny rozdział białek na żelu poliakrylamidowym w obecności siarczanu dodecylu (SDS-PAGE). Elektroforetyczny rozdział na żelu poliakrylamidowym (SDS-PAGE) wydaje się być efektywną metodą analityczną dającą informacje o ilościowych zależnościach pomiędzy głównymi frakcjami kazeiny i białkami serwatki. Może być jednakże obarczony błędem wynikającym z różnego stopnia wiązania barwnika przez poszczególne białka. Celem pracy było wyznaczenie współczynników korygujących ów błąd do obiektywnej oceny rozdzielonych elektroforetycznie głównych frakcji kazeiny (αs1 -, αs2 -, ß- і к) oraz białek serwatki (α-laktoalbuminy, β-laktoglobuliny i albuminy serum (BSA)) po ich wybarwieniu błękitem Coomassie Brilliant Blue R-250 według metody Laemmliego [1970]. Na podstawie otrzymanych wyników obliczono wartości współczynników pozwalających na określenie rzeczywistego, ilościowego udziału frakcji białkowych mleka, które wynoszą odpowiednio: dla αs1 -, αs2 -,ß- і к- kazeiny 1.00,1.00,1.07, 0.59 oraz dla α-laktoalbuminy, ß-laktoglobuliny i albuminy serum (BSA ) 1.00, 0.67, i 1.34. Analiza jakościowo-ilościowa pozwoliła na statystyczną ocenę wyników (Tabele 1 i 2). Wyznaczone wartości współczynników korelacji, pomiędzy stężeniem białka w badanej próbie, a wartością absorbancji (wyrażonej w jednostkach umownych — ilością impulsów integratora aparatu Vitatron MPS), dla poszczególnych białek (od 0.989 do 0.994) pozwalają na przyjęcie metody SDS-PAGE jako reprezentatywnej ilościowej analizy w określonym zakresie stężeń białka w próbie (1.00-6.00 mg/cm3 frakcje kazeinowe; 1.00-4.75mg/cm3 białka serwatki). Wyznaczone współczynniki pozwalają określić również bezwzględną zawartość danej frakcji w dowolnej próbce mleka o znanym stężeniu białka. Opisana metoda eliminacji błędu wynikającego z różnego stopnia wiązania barwnika przez poszczególne białka, modyfikująca interpretację odczytu wyników rozdziału elektroforetycznego, wydaje się być prostszą i bardziej uniwersalną formą ilościowej analizy białek mleka.

Opis:

Research background: There has been an extensive process of foreign and joint ownership enterprises establishment in the Russian economy since 2006. Domestic manufacturing industry has been experiencing certain pressure on behalf of foreign direct investment bringing new technologies and higher labor requirements. Purpose of the article: The aim of this paper is to investigate differences in employment strategies and labor indicators in the case of enterprises in foreign and joint ownership (FJO) and domestic enterprises in Russian ownership (RO). We analyze the manufacturing industry in Russia and its regions under conditions of stable and crisis periods. Methods: The study enhances the analysis of Rosstat's statistical data for 2005-2016 and applies ANOVA method to compare the employment results for companies with different ownership patterns. The research is carried out both at the national level of the Russian Federation and at the regional level according to the regions. Findings & Value added: The study identifies significant decline in employment and in-crease in productivity for the period of 2005-2016. In contrast to the crisis of 2008-2009, in 2014-2016 there has been no sharp drop in employment. However, there is a substantial decline in real salaries which is comparable to the crisis of 2008-2009. According to ANOVA, statistically significant differences in labor indicators between FJO and RO companies are manifested. RO companies dominate in employment and payroll funds, while FJO enter-prises have better productivity results with a higher average salary. FJO companies demonstrated faster growth in employment and payroll fund in relatively stable conditions (2012-2013). However, they reacted with a significant reduction in employment for a new crisis (2014-2016), although the creation of new FJO enterprises continued in separate regions of Russia. The results can be used in social policy to regulate the employment and earnings of industrial workers in the current economic conditions.

Rewriting books was a widespread phenomenon during the Baroque period of the Czech literature. The manuscripts were not always „honest copies”, on the contrary, scribes often compiled several sources or added their own texts to the original. The famous book Golden Key of Heaven by Martin of Cochem is compared with a manuscript Key of Heaven from a Regional museum in the town of Náchod. We use two statistical methods, both of them strongly indicate that the manuscript is a copy of some chapters from the Golden Key of Heaven rather than a compilation.

Opis:

Powszechnie macierzyństwo postrzegane jest, podobnie jak związana z nim rola matki, przez pryzmat różnorodnych stereotypów. Macierzyństwo stanowi jeden z najważniejszych etapów w życiu kobiety, a współcześnie wobec matek formułowane są różnorodne oczekiwania: aby potrafiły efektywnie zająć się pracą, domem, życiem rodzinnym, a przede wszystkim dziećmi. W opinii społecznej realizacja tych zadań powinna matkom zapewnić poczucie spełnienia życiowego, mimo psychofizycznego zmęczenia. Jednak nie zawsze tak jest – kobiety coraz częściej dzielą się otwarcie opiniami i doświadczeniami związanymi z przeżywanym macierzyństwem, przedstawianym bardziej realistycznie, ze wszystkimi jego wadami oraz zaletami. Ze względu na znaczenie macierzyństwa względem indywidualnego i społecznego życia w artykule została przedstawiona próba weryfikacji stereotypu Matki Polki w kontekście danych pochodzących z parentingowych komunikatów internetowych publikowanych przez współczesne matki. Na podstawie przeprowadzonych analiz zostało zidentyfikowane nowe zjawisko społeczne, związane z funkcjonowaniem w przestrzeni internetowej specyficznej grupy kobiet określonych przez autorki artykułu mianem „matek nowoplemiennych”. W tekście podjęto próbę odpowiedzi na pytania, jakie są cechy „nowoplemiennej matki” oraz jak określa ona problemy związane z macierzyństwem. Motherhood is widely perceived (similarly as the role of mother associated with it) through the prism of various stereotypes. Motherhood is one of the most important threads in a woman’s life and nowadays, many things are expected of mothers, such as: being effective at work, home, being able to take care of house and family, and above all, taking care of children. In the social opinion, being successful in all of these areas “should” give a mother a sense of fulfillment despite her psychophysical fatigue. However, this is not always the case – women more often share opinions and experiences related to the experience of motherhood, with all its advantages and disadvantages. Due to the importance of motherhood for individual and social life, this article presents an attempt to verify the stereotype of a Polish Mother in the context of parenting content published by modern mothers on the internet. Based on analysis, a new social phenomenon has been identified. There is a specific group of women functioning in the internet, they are described by the authors of the article as “neo-tribe mothers”. Authors made an attempt to answer the following questions, such as: what the characteristics of a “neo-tribe mother” are and how she identifies problems related to motherhood.

Do histogramów rozkładu zanieczyszczeń dopasowano statystycznie funkcję, której współczynniki można traktować jako parametry niepożądanych składników struktury. Przeanalizowano wpływ zawartości O, N, P i S na wartości współczynników funkcji aproksymującej.
The mechanical properties of cast steel are primarily a function of chemical composition and solidification conditions i.e. primary structure, however, a significant role also plays its quality understood as purity metallurgical i.e. as small as possible content of harmful components of the structure. In work the results of porosity and non-metallic inclusions in steel cast structure quantity analysis are presented. A function which coefficient can be treated as parameters of unwonted structure component was statistically fitted to histograms of impurities distribution. The influence of O, N, P and S content on approximation function coefficients was analyzed.

Opis:

Niektóre liotropowe układy ciekłokrystaliczne tworzące taśmowe układy micelarne mają zdolność tworzenia kompleksów z białkami pod warunkiem możliwości penetracji do wnętrza bryły białkowej. Możliwość taką stwarzają białka o niestabilnej strukturze w tym głównie białka patologiczne a także część białek należących do białek ostrej fazy. Modyfikacja ładunku białka w wyniku kompleksowania może być ujawniona w rozdziale elektroforetycznym. Dwukierunkowy rozdział elektroforetyczny z dodatkiem liganda supramolekularnego w drugim prostopadłym kierunku rozdziału pozwala na ujawnienie i izolację kompleksów z ciekłokrystalicznym ligandem. Otwiera to istotne możliwości diagnostyczne. Oczekiwane jest opracowanie numerycznej techniki ilościowej oceny proporcji ujawnionych frakcji białkowych. Wiązanie ligandów ciekłokrystalicznych okazuje się też aktualne w przypadku kompleksowania ich przez złogi amyloidowe. Czerwień Kongo jest w tym przypadku markerem specyficznym.
Some lyotropic liquide crystals of ribbon-like micellar structure form complexes with proteins of unstable structure due to possible penetration to their interior. Misfolded proteins and some acute phase serum proteins belong to that group. The altered charge of proteins engaged in complexation which becomes modified by the charge of bound ligand affects electrophoretic migration and allows differentiation of ubnormal proteins from among serum proteins. Two-dimensional agarose electrophoresis of serum proteins undergone complexation with supramolecular ligand after perpendicular reorganization of migration fulfils the requirement. The exposure of misfolded proteins and their quantitative analysis has a significant diagnostic meaning. Elaboration of numerical analysis is expected. Ligands in form of liquide crystals have been found to be bound to amyloids. Congo red appeared to be the specific marker for recognition of amyloid fibrils. This type of ligand seems to be the new category of ligands complexes in form of multimolecular system.

Opis:

This study describes the application of electrospray ionization mass spectrometry in order to identify ten antibiotics (macrolides, penicillins, aminoglycosides). An optimum procedure was developed for determination of antibiotics of different grade. Positive ion spectra of most antibiotics are higher in intensity including an [M+H]⁺ ion and produce less fragmentation and are more informative compared to the negative ion spectra. The group of antibiotics exhibits the same characteristic fragmentation. The data base was developed for identification of antibiotics comparing of their molecular and fragment ions. The results of the study showed that the method with electrospray ionization is simple and quick which is useful in the routine determination of antibiotics and in their pharmaceutical dosage forms.

Opis:

Women’s entrepreneurship is an important and interesting phenomenon from both economic and public point of view. It contributes to revive local and regional economic processes. In Poland, similarly as in other European countries, the situation of women on the labour market differs from men’s status of employment. Women’s entrepreneurship and their current situation on the labour market are being analyzed through the prism of differences which appears while comparing them with men. Differences are about the level of education, professional qualifications, payroll irregularities, also regulations and practices applied during the process of employing women. The purpose of this article is an analysis of women’s occupational activity on the base of statistical researches with particular reference to comparative surveys.
Przedsiębiorczość kobiet jest ważnym i ciekawym zjawiskiem zarówno z gospodarczego jak i publicznego punktu widzenia. Przyczynia się ona do ożywienia lokalnych i regionalnych procesów gospodarczych. W Polsce, podobnie jak w innych krajach europejskich, sytuacja statusu zatrudnienia kobiet na rynku pracy różni się od sytuacji mężczyzn. Przedsiębiorczość kobiet i ich obecna sytuacja na rynku pracy są analizowane przez pryzmat różnic, które pojawiają się podczas porównywania ich z mężczyznami. Różnice dają się zauważyć w poziomie wykształcenia, kwalifikacjach zawodowych, nieprawidłowościach płacowych, a także w przepisach i praktykach stosowanych w procesie zatrudniania kobiet. Celem niniejszego artykułu jest analiza aktywności zawodowej kobiet na podstawie badań statystycznych, ze szczególnym odniesieniem do badań porównawczych.

Opis:

The in vitro formation of transcription complexes with Escherichia coli RNA polymerase was monitored using fluorescence anisotropy measurements of labeled fragments of DNA. The multicomponent system consisted of holo or core RNA polymerase (RNAP) and lac or gal promoter fragments of DNA (in different configurations), in the presence or absence of CRP activator protein (wt or mutants) with its ligand, cAMP. Values of the apparent binding constants characterizing the system were obtained, as a result of all processes taking place in the system. The interaction of the promoters with core RNAP in the absence of CRP protein was characterized by apparent binding constants of 0.67 and 1.9 × 106 M-1 for lac166 and gal178, respectively, and could be regarded as nonspecific. The presence of wt CRP enhanced the strength of the interaction of core RNAP with the promoter, and even in the case of gal promoter it made this interaction specific (apparent binding constant 2.93 × 107 M-1). Holo RNAP bound the promoters significantly more strongly than core RNAP did (apparent binding constants 1.46 and 40.14 × 106 M-1 for lac166 and gal178, respectively), and the presence of CRP also enhanced the strength of these interactions. The mutation in activator region 1 of CRP did not cause any significant disturbances in the holo RNAP-lac promoter interaction, but mutation in activator region 2 of the activator protein substantially weakened the RNAP-gal promoter interaction.

The content analysis included materials containing the notion of gender, published in the editorial section of “Gazeta Wyborcza” between 2010–2014. The research showed that the issue of the social and cultural aspects of gender is more and more often present in the public debate, which is strongly polarized in nature. The gathered data allowed for the enumeration of subjects which include the context connected with gender and showed the essence of presenting this subject, in a specific Polish daily newspaper, casting light on the debate in this area.

The aim of the study was to examine the possibility of determination and optimization of methodology for analysis of three selected drugs: trimethoprim, sulfamethoxazole and diclofenac in urine using high-performance liquid chromatography, without extraction of the pharmaceuticals to the solid phase. The chromatographic separation conditions were determined using a gradient elution system and mobile phase, which was a mixture of acetonitrile and a phosphate buffer, allowing detection of trimethoprim, sulfamethoxazole and diclofenac from 260, 210 and 310 μg/L respectively, and simultaneous determination of these analytes in the presence of urine components.

Opis:

The study ascertains some physiochemical properties of soils around Power-line dumpsite at Boji-Boji Owa, Delta State, Nigeria. In order to evaluate the effects of municipal solid waste dumpsites on soils, soil samples were collected with the aid of a graduated soil auger at depths of 0 – 10 cm, 15 – 25 cm and 25 – 40 cm, representing top to sub and bottom soil sand also 500 m away from dumpsites which serves as control site (R). Samples were taken for laboratory analyses to determine the level of physiochemical properties such as: pH, grain size distribution, Electrical Conductivity (Ec), Organic Carbon (OC), Organic Matter (OM), Available Phosphorous (Av. P), Overall Nitrogen (ON), Basic Cations and Cation Exchange Capacity (CEC) in soils. Results obtained from the study, revealed that values between waste dumpsite and control site were significantly different. Findings showed that the pH value in sampled soils from studied dumpsites ranged from 6.22±0.06 and 7.97±0.04 while the mean pH value for controlled site was 39.8±0.08. The increase in the pH value of the sampled soil indicated an increase in CEC mean value of soil which ranged from 4.73±0.30 and 10.28±0.46 mEq/100 g while a low pH indicated low CEC mean value of 1.50±0.22 mEq/100 g. This is because there exists a positively significant relationship between pH, OC, OM, Av.P, ON, basic cations and CEC. As Ec varied between 692±4.50 to 918±4.03 μScm-1, OC varied between 0.05±0.00 to 0.64±0.03%, OM varied between 0.10±0.06 to 0.57±0.07%, Av.P varied between 8.98±0.06 to 25.36±0.22 mg/kg and ON varied between 0.44±0.01 to 0.93±0.03% across all studied dumpsites.

Opis:

In this work, authors investigated the effect of the Depth of Field (DoF) reduction, arising when the acquisition of small objects is carried out with a photogrammetry-based system using a Digital Single Lens Reflex (DSLR) camera and the structure from motion (SfM) algorithm. This kind of measuring instrument is very promising for industrial metrology according to the paradigms of the fourth industrial revolution. However, when increasing the magnification level, necessary for the reconstruction of sub-millimetric features, there is a corresponding decrease of the DoF, leading to possible effects on the reconstruction accuracy. Thus, the effect of the DoF reduction was analysed through the reconstruction of a well-known artefact: the step gauge. The analysis was conducted considering the theory behind the DoF concept, the analysis of the 2D images, input of photogrammetric reconstruction and, finally, the results in terms of dimensional verification of the reconstructed step gauge.

Opis:

In this summary, it is essential to highlight that in his statements, J. Kaczyński touches upon a narrow range of subjects. He uses merely 12 nouns on a regular basis (issue, politics, Poland, Prime Minister, democracy, law, society, country, opposition, truth, economy (or finance) and prices). He rarely addresses foreign policy issues and fails to specifically refer to historical facts. However, it is impossible not to notice his critical assessment of the Polish government's actions. The most prominent subject of Kaczyński's speeches are the current state of democracy in Poland. This sentiment is best captured by the quotation “it is a practice [here: about the actions of the Polish Sejm - author's note] which does not fit into the framework of democracy”. This tone is used to refer to the alleged breaching of opposition's law, which points out the terrible condition of Polish democracy. Kaczyński's speeches paint the picture that the basic provisions of democracy being broken. Among his claims are alleged lying to the society by those in power, lack of control mechanisms over the institutions guiding the country's actions, inequalities in Polish political procedure, and, most importantly the breaking of the laws of the opposition.

Opis:

Factors determining the Auger signal intensity are discussed. It is indicated that using standards is the only reasonable way for quantitative Auger analysis (QAA). Approaches to QAA without and with matrix corrections are presented. It is shown that the matrix correction connected with atomic concentrations of pure standards is the most important and that the other matrix corrections (e.g. those connected with the attenuation length and backscattering factor) do not improve appreciably the QAA exactness in many examples taken from the literature. The examples indicate that in the case of metallic alloys the properly performed QAA gives the relative atomic concentrations with the error not exceeding few percent.

This paper describes an approach that allows to reduce error propagation when comparing historical topographic maps. By linking the fuzzy set theory with simple map algebra and Kappa statistics, the uncertainty resulting from dissimilar quality of the maps can at least be partly eliminated and a distinction between ‘true’ and ‘false’ land cover changes can be made.

Przedstawiono wyniki badań doświadczalnych wpływu dodatków surfaktanta CTAB i soli NaSal na obniżenie strat ciśnienia przy przepływie wody w rurach. Stwierdzono, że największa redukcja dyssypacji energii występuje w stabilnej strefie przejściowej między ruchem laminarnym i turbulentnym. Zbadano wpływ średnicy rury i stężenia roztworu na wielkość i zasięg redukcji oporów. Zaproponowano równanie opisujące zmodyfikowaną krzywą oporów w stabilnej strefie przejściowej.
Experimental results of the influence of CTAB surfactant and NaSal salt additives on the pressure losses reduction for water flow in pipes are presented. It was found that the greatest reduction of energy dissipation is observed in the stable transitional zone between the laminar and turbulent flow ranges. The influence of pipe diameter and additives concentration on drag reduction efficiency was investigated. The equation of modified flow resistance curve in the stable transitional zone is proposed.

Opis:

Przeprowadzono badania doświadczalne mające na celu wykazanie równoważności określania gęstości strumienia ciepła przy pomocy ciepłomierza i techniki termografii. Pomiary doświadczalne przeprowadzono w komorze klimatycznej. Badano korelacje pomiędzy wartością gęstości strumienia ciepła pomierzoną ciepłomierzem i obliczoną na podstawie pomiarów termograficznych. Wartość współczynnika korelacji dla badanych przegród wynosi 0.95÷0.99. Wynika stąd, że dokładność pomiaru kamerą termograficzną jest wystarczająca do pomiarów ilościowych w budownictwie.
Determination of thermal properties of building partitions is becoming more important as the requirement for building certification is becoming obligatory. Data for energetic qualification of buildings is taken from their projects. This is a problem in case of old buildings, where there is usually no documentation. Thermography can be used for determination of the actual heat transfer coefficient, which can be useful for thermal assessment of such buildings. The existing norms say that thermography may be used for qualitative evaluation of building partitions. For the quantitative analysis, heat flow is measured with heat flow meters. Conducted investigations show that heat flow measurement with a thermographic camera is equivalent to a measurement taken with a heat flow meter. The investigations were performed in a climate chamber for four real-life partitions. The analyzed partitions were made with use of typical technologies. They differ in ability of heat accumulation. The measurements of the heat flow density were made with use of a heat flow meter. Thermographic cameras were used to record the surface temperature image and air temperature (Fig. 1). The heat flow density determined with the thermographic method had been calculated from formula (2). The correlation between the heat flow density measured by the heat flow meter and that calculated from the thermographic measurements was analyzed. The value of the determination coefficient R2 for the analyzed partition was between 0.91 and 0.99; while the correlation coefficient R between 0.95 and 0.99 (Tab. 1). The conclusion drawn from the investigations is that the accuracy of temperature difference measurements with use of a thermographic camera is good enough to be used for quantitative measurements.

Opis:

Podczas określania stanu termicznego budynków wyniknął problem oceny jakości przegród budowlanych pod względem przenikalności cieplnej, a co za tym idzie jakości zastosowanej izolacji. W związku z powyższym w Głównym Instytucie Górnictwa została opracowana metoda pomiarów i obliczeń współczynnika przenikalności cieplnej u z wykorzystaniem termogramów wykonanych kamerą termowizyjną oraz dodatkowych pomiarów temperatury powietrza wewnątrz i na zewnątrz budynku. Proces obliczania następnie zautomatyzowano, opracowując program komputerowy do ilościowej analizy obrazów termograficznych dla przegród budowlanych. Obecnie program "Termowizja budynków" ma następujące funkcje: - wyświetlanie wykonanych termogramów, - wyświetlanie dodatkowych fotografii w celu jednoznacznej identyfikacji badanego obszaru, - obliczanie temperatury średniej, minimalnej i maksymalnej dowolnie wybranego obszaru na termogramie, - obliczanie współczynnika przenikalności cieplnej u, - drukowanie wyników badań, - archiwizację wyników badań, - zarządzanie bazą danych. Obliczenia wykonywane są zgodnie z obowiązującymi w Polsce normami. Dzięki zastosowanej metodzie badań oraz opracowanemu programowi, można wykonywać między innymi badania przegród budowlanych w celu wykrycia ucieczek ciepła, obliczać współczynnik przenikania ciepła dla ścian zewnętrznych, stropów, okien itp., kontrolować prawidłowe wykonanie docieplenia budynków, wykonywać analizy jakości izolacji rurociągów ciepłowniczych.
During the determination of the thermal state of buildings resulted the problem of quality assessment of building partitions as regards the thermal permeability, and what follows, the quality of applied insulation. In connection with the above at the Central Mining Institute was developed the method of measurements and calculations of the thermal permeability coefficient u with the use of thermograms carried out by means of a thermovisional camera and additional measurements of the air temperature inside and outside of the building. The calculation process was then modernized, preparing a computer program to the quantitative analysis of thermographic images for building partitions. At the present time the program "Thermovision of buildings" has the following functions: - photo-copying of performed thermograms, - photo-copying of additional photographs in order to identify unambiguously the investigated area, - calculation of the average, minimum and maximum temperature of arbitrary selected area on the thermogram, - calculation of the thermal permeability coefficient u, - printing of investigation results, - keeping archives of investigation results, - data basis management. The calculations are carried out in conformity with standards being in force in Poland. Owing to the investigation methods and developed program, one can carry out among others investigations into building partitions in order to detect heat escapes, calculate the heat permeability coefficient for outside walls, floors, windows etc., control the correct execution of warming of buildings, perform analyses of insulation quality of heating pipelines.

Opis:

The aim of this paper is to present a possibility to use information technology in the form of databases for processing and analyzing large image sets based on methods of image analysis and mathematical morphology. Up to now the use of databases in the image analysis process has been reduced to storing large amounts of data in the form of images. However, all transformations and analyses of such sets are made on user’s computers. This requires a large data set (images) to be sent by network each time, and also it may possess the problems resulting from managing such large amounts of analyzed photographs on a computer. The proposed approach completely eliminates these problems by moving all transformations of image analysis to a database platform. For this purpose a set of routines realizing transformations of the image analysis and mathematical morphology was developed. The proposed approach allows the unification of the image processing and analysis area and advanced statistical analyses of obtained parameters describing geometrical sizes of objects on photographs. The proposed methodology was illustrated by practical realization of two measurement types for a simple structure of copper concentrate and more complicated, from the point of view of image analysis, structures such as dolomites from Redziny and Laskowa Gora and sandstones from Tumlin and Wisniowka.

Opis:

W niniejszym artykule przedstawiono zalety użycia ilościowej analizy cyfrowych źródeł pierwotnych w badaniach historycznych, wskazując, w jaki sposób może ona kwestionować przyjętą ortodoksyjność i tworzyć nowe wglądy. Autor użył bazy danych cyfrowych wersji brytyjskich czasopism faszystowskich z lat trzydziestych XX wieku w celu stworzenia dużej, spójnej i miarodajnej próby faszystowskiego dyskursu we wspomnianym okresie. Używając metody kodowania, zarejestrował wszystkie wzmianki o Żydach występujące w tej próbie. Umożliwiło mu to prześledzenie w czasie rozwoju antysemityzmu faszystów w kontekście jego ilości, typologii i uwydatnienia w dyskursie. Użyta metoda – w połączeniu z bardziej tradycyjną analizą źródeł –kwestionuje różne przyjęte i powszechnie uznawane aspekty właściwej historiografii. W szczególności, przedstawia on, że dotychczasowa jednomyślność historyków dotycząca chronologii rozwoju antysemityzmu brytyjskich faszystów jest błędna. W jej miejsce proponuje nowy, pięciostopniowy model jego rozwoju.  Dokładniejsza linia czasu pozwala mu w bardziej przejrzysty sposób wyjaśnić motywy i ideologię przyświecającą stosunkowi faszystów do Żydów.
This article illustrates the benefits of employing quantitative analysis of digitised primary sources in historical research, demonstrating how it can challenge old orthodoxies and create new insights. The author has used a database of scanned copies of British fascist newspapers from the 1930s to create a large, consistent and representative sample of fascist discourse during this period. Employing a coding methodology, the author has recorded all mentions of Jews within that sample, enabling him to trace over time the evolution of the fascists’ antisemitism, in terms of its quantity, typology and prominence within their discourse. This approach—in combination with more traditional analysis of sources—challenges various longestablished and widely accepted aspects of the relevant historiography. In particular, the author demonstrates that the consensus among historians regarding the chronological evolution of British fascist antisemitism is false, and instead he presents a new, fivestage model of its development. This more accurate timeline allows the author to offer a clearer explanation of the motives and ideology that underlay the fascists’ attitude towards Jews.

Opis:

Morphometric attributes of 705 stromatoporoid specimens from a number of exposures from the Silurian of Podolia (Ukraine) and the Devonian of the Holy Cross Mountains (Poland), representing a wide array of shallow water carbonate sedimentary environments, have been analysed. Taken into account were such parameters as: general shape of the skeleton, shape of the final growth form (living surface profile), upper surface character, latilaminae arrangement, burial ratio and type of initial surface. A number of new ratios has been introduced, designed mainly to improve the mapping of the outlines of the stromatoporoids upper surfaces. All studied specimens were treated as belonging to one group, and relations between particular attributes were tested. The results were analysed in terms of potential environmental factors influencing stromatoporoid morphometric features. Most of the distinguished attributes are common in the studied group and occur in various combinations, with an important exception of parameters designed to reflect the shape of the skeleton’s upper surface, which are distinctly predominated by convex variants. This indicates that surface concavity was a highly undesired feature among stromatoporoids. Upper surface convexity is interpreted herein as a response to the hazard of clogging of the animals pores by tiny sediment particles suspended in the bottom turbid water layer. Common low burial ratios of final living surface profiles and the occurrence of specimens with a smooth upper surface but a non-enveloping latilaminae arrangement are other reflections of this phenomenon. Burial by sediments and redeposition were also important factors governing stromatoporoid development. No direct arguments indicating photosensitivity of stromatoporoids can be deduced from the presented results. The hitherto postulated allometric tendency among stromatoporoids of starting growth as laminar forms and later adopting consecutively higher profile shapes has not been confirmed here. On the contrary, a tendency for gradual elimination of very high profile forms with increasing stromatoporoid size has been observed. The final shape of a stromatoporoid skeleton was always an effect of a combination of various agents.

Since ancient times, scholars points out effectiveness of horseback riding not only for utilitarian use, but also as form of therapy for less healthy part of society. Enlightenment age scholars started to make treaties about use of such therapy and this trend is now developing not only for physical disabilities, but also for mentally ill patients. The purpose of this study is to determine trends of interest in horseback riding therapy interventions among different groups of neurocognitive disorders among different populations of people and its comparison to prevalence of such disorders. Material and methods: Web of Science, Pubmed and Scopus databased were screened using filter with algorithm of “horseback therapy” , “horse back therapy”, ”hippotherapy” and “equine therapy”. Results were screened for appropriateness and relevance, then based on this end-filtering, papers were grouped regarding specificity of neurocognitive aspect of disorders. Results: 595 entries in Web of Science, 516 entries in Scopus and 123 results in Pubmed. Overall, 272 entries were subtracted. Conclusions: This analysis shows that most interest in such kind of therapy is focused on neurological disorders, especially with ones with cerebral palsy. There is no correlation between prevalence of selected disorders and amount of related papers.

Opis:

The dredger fill of Shanghai Hengsha Island Dongtan is solidified by curing agents with different fly ash content, and the shear strength index of solidified dredger fill is measured by the direct shear test. The microscopic images of solidified dredger fill are obtained by using SEM. The microscopic images are processed and analyzed by using IPP, and the fractal dimension including particle size fractal dimension Dps, aperture fractal dimension Dbs and particle surface fractal dimension Dpr is calculated by fractal theory. The quantitative analysis of the relationship between shear strength index and fractal dimension of solidified dredger fill is done. The research results show that the internal friction angle and the cohesion are closely related to the fly ash content λ and the curing period T, and the addition of fly ash can improve the effect of curing agent; There is no obvious linear relationship between the internal friction angle and the three fractal dimensions; The smaller particle surface fractal dimension Dpr and particle size fractal dimension Dps, the larger aperture fractal dimension Dbs, the greater the cohesion, and the cohesion has a good linear relationship with three fractal dimensions, and the correlation coefficient R2 is above 0.91.

Opis:

An extension of deformationally self-consistent approach to a quantitative analysis of adiabatic and nonadiabatic effects in vibration-rotational spectra of diatomic molecules is presented. We consider vibrational displacements of nuclei in the vicinity of dynamical reference conformation R$\text{}_{vJ}$ that depends not only on the rotational quantum number J through the action of centrifugal force, but also on the vibrational v one, through nonadiabatic vibrational effects of high order. The method is applied to LiH X$\text{}^{1}$Σ$\text{}^{+}$; reported wave numbers of transitions are reproduced with σ̂=1.090 and F=5.98×10$\text{}^{14}$ using 14 independently adjusted parameters and 14 constrained parameters t$\text{}_{i=0-6}^{Li,H}$, representing nonadiabatic rotational effects. The latter have been evaluated from the rotational g-factor and electric dipole moment of LiH, both electronically computed.

Opis:

In the research on children’s articulation, several types of attempts to assess the implementation of phonemes are usually taken into account. An image questionnaire is a tool allowing us to study articulation. The purpose of using this kind of aid is to either indicate or exclude a speech disorder – in this case, for example, regarding the faulty implementation of individual phonemes. The article analyses quantitatively one of the phonological aspects of the lexical content of ten selected diagnostic tests used to study the articulation of children between the ages of three and seven. The studies include the occurrence of consonant groups, the attention to the position of the appearance of consonant clusters, their number in the lexical unit, and the quantity of consonant elements adjacent to each other.

Opis:

A quantitative risk analysis (QRA) should provide a comprehensive, informative and balanced picture of risk, in order to support decisions. To achieve this, a proper treatment of uncertainty is a prerequisite. Most approaches to treatment of uncertainty in QRA seem to be based on the thinking that uncertainty relates to the calculated probabilities and expected values. This causes difficulties when it comes to communicating what the analysis results mean, and could easily lead to weakened conclusions if large uncertainties are involved. An alternative approach is to hold uncertainty as a main component of risk, and regard probabilities as epistemic-based expressions of uncertainty. In the paper the latter view is taken, and we describe what should be the main pillars of a risk description following this approach. We also indicate how this approach should relate to decision-making. An important issue addressed is how to communicate the shortcomings and limitations of probabilities and expected values. Sensitivity analysis plays a key role in this regard. An example is included to illustrate ideas and findings.

Opis:

W 2006 r. z inicjatywy sześciu gmin powiatu miechowskiego powstało Miechowskie Stowarzyszenie Gmin „Jaksa”, które skupia przedstawicieli trzech sektorów: społecznego, gospodarczego i publicznego. Obecnie tworzą je: 96 członków (osoby fizyczne) i 7 samorządów gminnych, starostwo powiatowe w Miechowie oraz trzy organizacje pozarządowe. Działalność skupia się przede wszystkim na rozwoju obszarów wiejskich. W ramach działalności statutowej stowarzyszenia została opracowana Lokalna Strategia Rozwoju (LSR). W latach 2009-2015 Lokalna Grupa Działania (LGD) przy Miechowskim Stowarzyszeniu Gmin „Jaksa” realizowała projekty zawarte w priorytetach Lokalnej Strategii Rozwoju, mianowicie: „Wartość dodana do życia na wsi”, czyli wzrost poziomu i jakości życia, a także aktywizacja i integracja mieszkańców oraz „Poprawa atrakcyjności turystycznej i promocja produktu lokalnego”, w tym rozwój turystyki, zachowanie lokalnego dziedzictwa kulturowego i historycznego. To główne kierunki działań Stowarzyszenia powołanego po to, aby w oparciu o środki unijne zaktywizować społeczność lokalną do budowania infrastruktury i wspólnego działania na rzecz rozwoju obszaru. W latach 2007-2015 na realizację zadań na terenie powiatu miechowskiego przeznaczono ok. 7,5 mln zł. Były to zadania, takie jak: „Małe projekty”, „Odnowa i rozwój wsi”, „Tworzenie i rozwój mikroprzedsiębiorstw” i „Różnicowanie w kierunku działalności nierolniczej”. Celem artykułu jest: -  określenie efektów działań i operacji realizowanych w ramach poszczególnych przedsięwzięć zgodnych z Lokalną Strategią Rozwoju, -  analiza liczby projektów realizowanych w ramach każdego z przedsięwzięć wraz z oceną, które są najlepiej oraz najgorzej realizowane, - przedstawienie struktury grup beneficjentów wnioskujących o wsparcie.
In 2006, upon the initiative of six municipalities of the Miechow district, Miechow Association of Municipalities “Jaksa” was founded. It brings together representatives of three sectors: social, economic and public life sector. It has currently 96 members (individuals) and seven local governments, county authorities in Miechow, and three non-governmental organizations. Its main activity focuses on rural development. As part of statutory activities, the association developed Local Development Strategy. In the years 2009-2015, Miechow Association of Municipalities “Jaksa” Local Action Group implemented projects which included the priorities of the Local Development Strategy, namely: “Added Value” to rural life - that is, an increase of the level and quality of life, as well as the activation and integration of citizens, and “Improvement of tourist attractiveness and promotion of local products” which includes development of tourism and preservation of the local cultural and historical heritage. These are the main ways of the Association, established on the basis of EU funds, in order to activate local community to build infrastructure and join actions for the development of local area. In the years 2007-2015, for the implementation of tasks in the Miechow district, about 7.5 million PLN has been allocated. Tasks carried out in the framework of the program included: diversification, creation and development of micro-enterprises, “Village renewal” and “Small Projects”. The purposes of this article are: -  identification of effects of actions and operations carried out within the framework of individual projects consistent with the Local Development Strategy, -  analysis of the number of projects under each of ventures together with an evaluation of which projects are the best and the worst implemented, -  presentation of the structure of beneficiary groups that request support.

Opis:

The objective of the research was a survey identification of the presence of the history of Communist Poland, PRL, in museum narrative in 1989–2017. Importantly, this is a repeated, supplemented, and more thorough research versus the one presented in the paper ‘PRL in Museum Narrative over the Last 25 Years’ published in 2014 in the Światowid. Rocznik Muzeum PRL-u (w organizacji) periodical. The research discussed in the present paper forms part of a doctoral dissertation, constituting the research’s second stage. As a result of the conducted research based on survey answers provided by museums and on individual research a database containing 642 exhibitions was created. When processing the data, quantitative analysis was adopted. After data cleaning the following statistical trends were analysed: exhibition duration over the whole research period, percentage of leading themes, percentage of themes in respective cities. The conducted analysis has permitted to observe trends in museum narrative concerning PRL. Also the most popular exhibition duration over the research period has been identified (up to two years and permanent exhibitions). The most popular categories have been named: art history, political history, history of everyday life. Three groups of urban centres where museum narrative is present to a varied degree have been named. The fourth group contains cities in whose museums the topic of PRL has not been tackled over the last 28 years, or such projects cannot be reliably confirmed.

Opis:

Analiza półilościowa składu mineralogicznego skał przy pomocy przenośnego spektrometru FT-IR jest metodą szybką i może stanowić ciekawą alternatywę dla innych metod analitycznych, takich jak XRD i XRF. Modele stworzone za pomocą algorytmu Beera będące podstawą do opracowania metodyki do analizy półilościowej dają bardzo dobre rezultaty, charakteryzując się wysokim współczynnikiem determinacji R2 dla widm podczerwonych oraz metod XRD i XRF. Przenośny spektrometr FT-IR może być z powodzeniem użyty zarówno w pomiarach laboratoryjnych, jak i terenowych. Metoda FT-IR może umożliwić szybką ocenę litologiczną przewiercanych warstw oraz jest pomocna przy wyborze prób do dalszych badań laboratoryjnych. W niniejszym artykule przedstawiono wstępne wyniki analizy półilościowej składu mineralogicznego skał zbiornikowych opartej na korelacji widm FTIR z wynikami analiz XRF i XRD.
Semi-quantitative analysis of mineralogical composition of reservoir rocks with the use of portable FT-IR spectrometer is a quick analytical method and might be an interesting alternative to other methods such as XRD and XRF. Models created using Beer’s algorithm being the basis of methodology for semi-quantitative analysis, have given very good results with a high R2 determination coefficient, for infrared spectra and methods such as XRD and XRF. Portable FT-IR spectrometer can be successfully used for laboratory analyses as well as field measurements. The opportunity to analyze the mineralogical composition of rocks allows for quick lithological assessment of drilled layers and helps during sampling for further laboratory testing. This article shows preliminary results of semi-quantitative analyses of mineralogical composition of reservoir rocks based on correlations of infrared spectra with XRF and XRD results.

W artykule przedstawiono wyniki badań wpływu warunków wytapiania i odlewania eksperymentalnych stali zawierających 3÷5% glinu na rodzaj i morfologię wtrąceń niemetalicznych. Wytopy badawcze wykonano w elektrycznym piecu indukcyjnym z zastosowaniem próżni oraz w atmosferze powietrza. Przeprowadzono analizę ilościową i jakościową wtrąceń niemetalicznych po przeróbce plastycznej na gorąco. W stalach wytapianych i odlewanych w powietrzu występują głównie wtrącenia AlN, MnS, Al2O3 oraz złożone wtrącenia tlenkowo-siarczkowe. Udział objętościowy wszystkich wtrąceń niemetalicznych stanowi 0,10÷0,12% obj. i jest większy o ok. 30% w porównaniu ze stalą wytapianą w próżni.
The paper presents the effect of melting and casting conditions of experimental steels with 3÷5% of aluminium on the type and morphology of non-metallic inclusions. The experimental heats were carried out in an electric induction furnace in vacuum and in air atmosphere. A quantitative and qualitative analysis of non-metallic inclusions was conducted after hot plastic working. Steels which were melted and casted in air atmosphere contain mainly AlN, MnS, Al2O3 and complex oxide-sulfide inclusions. The volume fraction of non-metallic inclusions was 0.10÷0.12% and it was about 30% higher than the volume of inclusions in the steel produced in vacuum.

Opis:

Background: Use of mouthwash and an increased risk of oral cancer has been a source of controversy for decades. A metaanalysis of epidemiological studies of mouthwash and oral cancer and, specifically, mouthwash containing >25% alcohol, was undertaken. Methods: Summary estimates were obtained with maximum likelihood estimates from random effects models. Sensitivity analyses were conducted to evaluate the influence of various inclusion. Results: Eighteen studies were included in the meta-analysis. There was no statistically significant associations found between regular use of mouthwash and risk of oral cancer (RR=1.13; 95% CI (0.95-1.35)). There was no significant trend in risk of oral cancer associated with increased daily usage of mouthwash (p=0.11). There was no association between reported use of mouthwash specifically containing alcohol and risk of oral cancer (RR=1.16; 95% CI (0.44, 3.08)). Conclusions: This quantitative analysis of mouthwash use and oral malignancy revealed no statistically significant associations between mouthwash use and risk of oral cancer, nor any significant trend in risk with increasing daily use; and no association between use of mouthwash containing alcohol and oral cancer risk.

Opis:

The aim of this study was to analyze the molecular mechanism of inositol hexaphosphate (InsP6) action through which it may inhibit proliferation of colon cancer cells and cell cycle progression. A kinetic study of p53 and p21WAF1 mRNA increase was performed on human colon cancer HT-29 cells after treatment with 1, 5 and 10 mM InsP6 for 6, 12, 24 and 48 h. Real-time-QPCR based on TaqMan methodology was applied to analyze quantitatively the transcript levels of these genes. The transcription of β-actin and GAPDH genes was assessed in parallel to select the control gene with least variability. The 2-ΔΔCt method was used to analyze the relative changes in gene transcription. InsP6 stimulated p53 and p21WAF1 expression at the mRNA level, with the highest increase in p21WAF1 mRNA occurring at 24 h, i.e., following the highest increase in p53 mRNA observed at 12 h. Based on these studies it may be concluded that the ability of InsP6 to arrest the cell cycle may be mediated by the transcriptional up-regulation of the p53-responsive p21WAF1 gene.

Opis:

Morphometric attributes of 705 stromatoporoid specimens from a number of exposures from the Silurian of Podolia (Ukraine) and the Devonian of the Holy Cross Mountains (Poland), representing a wide array of shallow water carbonate sedimentary environments, have been analysed. Taken into account were such parameters as: general shape of the skeleton, shape of the final growth form (living surface profile), upper surface character, latilaminae arrangement, burial ratio and type of initial surface. A number of new ratios has been introduced, designed mainly to improve the mapping of the outlines of the stromatoporoids upper surfaces. All studied specimens were treated as belonging to one group, and relations between particular attributes were tested. The results were analysed in terms of potential environmental factors influencing stromatoporoid morphometric features. Most of the distinguished attributes are common in the studied group and occur in various combinations, with an important exception of parameters designed to reflect the shape of the skeleton’s upper surface, which are distinctly predominated by convex variants. This indicates that surface concavity was a highly undesired feature among stromatoporoids. Upper surface convexity is interpreted herein as a response to the hazard of clogging of the animals pores by tiny sediment particles suspended in the bottom turbid water layer. Common low burial ratios of final living surface profiles and the occurrence of specimens with a smooth upper surface but a non-enveloping latilaminae arrangement are other reflections of this phenomenon. Burial by sediments and redeposition were also important factors governing stromatoporoid development. No direct arguments indicating photosensitivity of stromatoporoids can be deduced from the presented results. The hitherto postulated allometric tendency among stromatoporoids of starting growth as laminar forms and later adopting consecutively higher profile shapes has not been confirmed here. On the contrary, a tendency for gradual elimination of very high profile forms with increasing stromatoporoid size has been observed. The final shape of a stromatoporoid skeleton was always an effect of a combination of various agents.

Opis:

Qualitative and quantitative analysis of phenolic acids present as free and liberated from their conjunction with sugars and alcohols after hydrolysis in Salsola kali L was done, together with comparison of their content in roots and herb. Analysis was conducted by 2D-TLC and HPLC methods. Eleven phenolic acids were identified such as: protocatechuic, caffeic, gentisic, p-coumaric, p-hydroxybenzoic, p-hydroxyphenylacetic, syryngic, vanillic, ferulic, α- and ß-resorcylic. Differences in composition of fraction of free phenolic acids and those liberated after hydrolysis were noticed. The amount of individual compounds were in the range between 0.10±0.04 mg/100 g of dry weight for p-OH-benzoic acid and 6.40±1.75 mg/100 g of dry weight for ferulic acid.

Opis:

This study is a detailed lithofacies analysis of the Wiar and Leszczyny members of the deep-marine Ropianka Formation (Campanian–Paleocene) exposed in the Hucisko Jawornickie section of the Skole Nappe, Polish Carpathian Flysch. The sedimentary succession (>400 m thick) represents a channelized lobe complex that prograded at the base of submarine slope. Seven sedimentary facies are recognized as a record of the principal modes of sediment deposition. Based on their stratigraphic grouping and grain-size trends, six facies associations are distinguished as representing specific sub-environments of the depositional system: distributary channels, channel-mouth lobes, channel levees, crevasses and interlobe basin plain with crevasse splays. The individual facies associations are characterized statistically and their internal facies organization is analysed by the method of embedded Markov chains to reveal the time pattern of depositional processes. The environmental changes indicated by the vertical succession of facies associations are attributed to the autogenic processes of the distributary channel shifting within an aggrading lobe area and the lateral switching of depositional lobes. Eustatic influences are likely, but difficult to ascertain with poor biostratigraphic data. The bulk basinward advance of the base-of-slope system was probably due to a pulse of the tectonic narrowing of the synclinal Skole Basin.

Opis:

The IN713C is nickel-based superalloy, used to produce low pressure turbine blades in a process of investment casting. However, porosity which is formed during the casting, decreases mechanical properties of IN713C. Therefore, to eliminate porosity, a process of hot isostatic pressing was applied. Nonetheless, HIP also least to some changes in the microstructure of tested material. The main aim of this paper is to characterize the morphology of carbides before and after hot isostatic pressing. Microstructural characterization was carried out with the use of a scanning electron microscope equipped with an energy dispersive X-ray spectrometer and an electron backscatter diffraction detector. The size and shape of carbides were evaluated by quantitative metallography methods methods. The results show that the amount, size and heterogeneity of arrangement of the carbides increased after application of HIP treatment.

Opis:

Obwohl nach Marx/Weidacher (2014:91ff.) von keiner Internet-Sprache die Rede sein kann, ist leider die in Diskussionen und Kommentaren auf Facebook, Twitter oder Weblogs genutzte Sprache, oft gefüllt von beleidigenden, hassvollen Wörtern und Ausdrücken. Genau diese Art von Sprache wird als Hasssprache (auch Hassrede) genannt. Im folgenden Beitrag wird die Hasssprache am Beispiel von deutschen, dänischen und polnischen Facebook-Kommentaren zum Terroranschlag in Manchester (Mai 2017) analysiert. Es wurde eine qualitative Analyse durchgeführt, indem die Stellungnahmen in Bezug auf die dort vorkommenden Wörter und Wendungen, die in allen drei genannten Sprachen als beleidigend betrachtet werden, untersucht werden. Ich versuche dabei, folgende Fragen zu beantworten: Welche sprachlichen Mittel sind für die Kommentare charakteristisch? Sind irgendwelche von diesen Mitteln speziell bevorzugt? Welches Ziel möchten die Kommentierenden erreichen? Welche Inhaltsunterschiede lassen sich zwischen deutschen, dänischen und polnischen Kommentaren feststellen? Welche Aspekte des Inhalts berühren sie?

The following paper contains an qualitative analysis of comments, which appeared on Facebook in Germany, Denmark and Poland after the terrorist attack in Manchester in May this year. I try to find answer on following questions: Which linguistic methods are characteristic for such comments? Are some of these methods preferred? What are the authors of such comments trying to achieve? What are the differences between German, Danish and Polish comments? Which aspects of content do they touch?

Opis:

This is an empirical quantitative analysis of the official data coming from the Polish Ministry of Science and Higher Education. The foreign scholars in Poland at the beginning of the 21st century are presented in the context of the global “brain circulation” or migration of highly qualified specialists. The second context is the present Polish academic system. In this paper we discuss characteristics of the analysed data base, universities and colleges where the foreign scholars are usually employed, the academic disciplines they represent, the relations between the number of foreign scholars and the institutional prestige of schools employing them, and conclusions on what we can and cannot learn from the data set analysed here.
