Opis:
Development and geographical expansion of multinational corporations makes it more complex and more often we are dealing with cultural diversity within teams of employees. Mutual cooperation of foreigners and local staff raises many intercultural interactions, both negative and positive. The purpose of this article is to identify the benefits and weaknesses arising from intercultural interactions between foreigners and local staff in the German subsidiary operating in Poland. The research procedure was a case study and a method was 12 structured interviews with Polish managers. Research problems concerned the general perception of Polish managers in relation to cooperation with foreigners. The respondents indicated the benefits and problems of this cooperation, as well as practical guidance (advice) to improve these interactions. This case study enriched the empirical achievements in the area of the new trend in management sciences, which is the positive organizational scholarship (POS).

The problem of monetary aspect of welfare in employees’ household was undertaken in this paper. In order to identify the households in danger of poverty, the binary logit models approach was applied. It was found that the estimation of models without the interaction terms results in misspecification error. Due to this, the interaction terms, between the socio-economic factors of households were included in the model. The obtained results can have significant importance in the aspect of social policy in Poland.

Opis:
Using the B3PW91/6-31G(d) computational procedure, we fnd two types of complexes to be formed between aliphatic amines and 2,4,6-trinitrotoluene (TNT). Type 1 are noncovalent, primarily electrostatic interactions that occur in the vicinities of the NO2 groups; Type 2 are δ-adducts, at carbons 1, 3 and 5. In Type 1, the TNT framework is very little affected. In Type 2, however, the site of the complex becomes quasi-tetrahedral, with longer bonds to its neighbors in the ring; the C-NO2 bonds are shortened. The Type 1 complexes have weakly negative (attractive) interaction enthalpies. For one of them, utilizing a chargetransfer formalism, we obtained a wave length for an electronic transition to a low-lying dative excited state that is in good agreement with observed values. The Type 2 interaction enthalpies are near-zero or even positive; however all of the complexes correspond to energy minima (no imaginary frequencies). For one of the Type 2, a transition state to a nitronic acid was found, with an activation enthalpy of only 5.6 kcal/mole. This indicates a possible route for amine-induced decomposition of TNT.

Opis:
The aim of this study was to investigate the association between students’ gender and teacher-student interactions in a sample of Botswanan junior secondary school Physical Education lessons. Ninety-six lessons taught by male and female physical education teachers were observed, coded, and analysed for gendered interaction patterns. Chi-square test of independence was used for data analysis. The level of statistical significance was set at p <. 05. Results reveal a statistically significant association between students’ gender and teacher-student interactions with respect to task allocation and misbehaviour management. No significant associations were found between students’ gender and teachers’ questions and feedback. The study concludes that systematic observations of pedagogical interactions in physical education settings are necessary to highlight deeply entrenched gender equity issues in co-educational classrooms. Physical education teacher preparation programmes must impress upon pre- and in-service candidates the importance of and different approaches to enacting gender-sensitive instructional practices. Providing physical education teachers with contextualized pedagogical directions and resources for analysing and addressing gender bias in their classroom will equip them to create inclusive, interactive, respectful, equitable, and productive lessons.

Opis:
Metabolic and toxicodynamic interactions of some organic solvents in rats repeatedly treated with medium dose levels were examined. It was shown that both n-hexane and ethylbenzene significantly inhibited tetrachloroethylene metabolism during a 2-week period. n-Hexane and tetrachloroethylene enhanced metabolism of ethylbenzene whereas ethylbenzene suppressed n-hexane metabolism only at the end of the experiment. Biochemical changes, especially the drop in the level of non-protein sulfhydryl groups in tissues of rats treated with organic solvent mixtures, were significantly less pronounced than those observed after these chemicals were administered separately. These results demonstrate that metabolic interactions between hydrocarbons and chloroalkene may lead to a modification of the biological response to these compounds.

Opis:
Structural bioinformatics approaches applied to the alpha- and beta-glycosidases from the GH4 enzyme family reveal that, despite low sequence identity, these enzymes possess quite similar global structural characteristics reflecting a common reaction mechanism. Locally, there are a few distinctive structural characteristics of GH4 alpha- and beta-glycosidases, namely, surface cavities with different geometric characteristics and two regions with highly dissimilar structural organizations and distinct physicochemical properties in the alpha- and beta-glucosidases from Thermotoga maritima. We suggest that these structurally dissimilar regions may be involved in specific protein-protein interactions and this hypothesis is sustained by the predicted distinct functional partners of the investigated proteins. Also, we predict that alpha- and beta-glycosidases from the GH4 enzyme family interact with difenoconazole, a fungicide, but there are different features of these interactions especially concerning the identified structurally distinct regions of the investigated proteins.

Opis:
Methionyl-tRNA synthetase (MetRS) belongs to the family of 20 enzymes essential for protein biosynthesis. It links covalently methionine with its cognate tRNA. Crystal structures solved for bacterial MetRSs have given a number of interesting insights into enzyme architecture and methionylation catalysis. A comparison of sequences of MetRSs belonging to all kingdoms of life, as well as numerous biochemical and genetic studies have revealed the presence of various additional domains appended to the catalytic core of synthetase. They are responsible for interactions with tRNA and proteins. Tertiary structure of C-terminal tRNA-binding appendices can be deduced from those determined for their homologues: tRNA binding protein 111 and endothelial monocyte-activating polypeptide II. Contacts between MetRS and other proteins could be mediated not only by noncatalytic peptides but also by structural elements present in the catalytic core, e.g. Arg-Gly-Asp (RGD) motifs. Additional activities involve MetRS in the maintenance of translational fidelity and in coordination of ribosome biogenesis with protein synthesis.

Opis:
In this investigation, galvanic interaction between galena and pyrite in flotation and its effect on floatability of pyrite were studied. Rest and mixed potential studies in the presence and absence of a collector indicated that pyrite was nobler than galena under all investigated conditions. Therefore, pyrite served as a cathode in galvanic interactions with galena. Floatability of pyrite was performed alone and as a mixture with galena in the ratios of pyrite to galena equal to 1:4, 1:1 and 4:1. The experiments were conducted with air and nitrogen. In any galvanic contact between pyrite and galena, anodic oxidation occurred on the galena surface, and hydrolysed lead species adsorbed on the pyrite surface. The investigation of the various reactions occurring on the sample surface was investigated by ethylene diamine-tetra acetic acid disodium salt (EDTA) extraction and X-ray photoelectron spectroscopy (XPS) measurements. In the presence of nitrogen, floatability of pyrite increased. The recovery of pyrite in the presence of air was 22%, while in the mixture with galena (ratio 1:4) the recovery increased to 43%. The results indicated that the presence of galena improved floatability of pyrite.

The aftermath of influenza infection is determined by a complex set of host-pathogen interactions, where genomic variability on both viral and host sides influences the final outcome. Although there exists large body of literature describing influenza virus variability, only a very small fraction covers the issue of host variance. The goal of this review is to explore the variability of host genes responsible for host-pathogen interactions, paying particular attention to genes responsible for the presence of sialylated glycans in the host endothelial membrane, mucus, genes used by viral immune escape mechanisms, and genes particularly expressed after vaccination, since they are more likely to have a direct influence on the infection outcome.

Opis:
Canthaxanthin (β,β-carotene 4,4' dione) used widely as a drug or as a food and cosmetic colorant may have some undesirable effects on human health, caused mainly by the formation of crystals in the macula lutea membranes of the retina of an eye. Experiments show the exceptional molecular organization of canthaxanthin and a strong effect of this pigment on the physical properties of lipid membranes. The most striking difference between canthaxanthin and other macular pigments is that the effects of canthaxanthin at a molecular level are observed at much lower concentration of this pigment with respect to lipid (as low as 0.05 mol%). An analysis of the molecular interactions of canthaxanthin showed molecular mechanisms such as: strong van der Waals interactions between the canthaxanthin molecule and the acyl chains of lipids, restrictions to the segmental molecular motion of lipid molecules, modifications of the surface of the lipid membranes, effect on the membrane thermotropic properties and finally interactions based on the formation of the hydrogen bonds. Such interactions can lead to a destabilization of the membrane and loss of membrane compactness. In the case of the retinal vasculature, it can lead to an increase in the permeability of the retinal capillary walls and the development of retinopathy.

The purpose of serving a prison sentence is not isolating but inducing the perpetrators of crimes to refrain from committing offences in the future. This is possible when there are positive changes in their attitudes, and in particular when they create a need to respect the legal order and a sense of responsibility for their actions. For this purpose, in addition to other means of influence such as work, education, social contacts, cultural and educational activities and sports, or therapy, it is proposed to the detainees to participate in group resocialization programs. The article presents an example of resocialization program dedicated to convicted juveniles entitled “Butterfly Effect”. It presents the theoretical foundations of the program, the spectrum of objectives and results, the methods to achieve them, and scenario activities.

This paper analyses the complexity of family life, which includes both its charismatic and institutional aspects. Deepening the understanding of this basic social group can be useful in explaining how human beings in their decisions and actions, as well as organizations, unceasingly transcend different oppositions and dimensions. Undertaking this topic is not only important in the context of understanding the fundamental and complex experience of family life in the process of preparing and introducing new members to society, but also from the organizational perspective. It means that exploring the role of both dimensions – charismatic and institutional – which are somehow complementary, is crucial for understanding and harmonizing the different relationships and interactions within organizations, including business ones. In this way the article shows the connection between the functioning of the family and society (including organizations within it).

The model proposed encompasses the six fundamental dimensions of family functioning, including those of subjectivity and plasticity. The model can be applied in analyses of families with a disabled as well as a fully fit child.

Opis:
The results of a combined study of bornite with Mossbauer spectroscopy, X-ray diffraction and DC magnetometry are reported. The orthorhombic crystallographic structure of the mineral is observed at 15 K and 300 K. It exhibits an increase of the orthorhombic distortion with decreasing temperature. Magnetic susceptibility shows a Curie-Weiss like behaviour between 230 K and 380 K corresponding to the effective magnetic moment of 7.2(3) mi B per formula unit. The material undergoes a transition to an antiferromagnetic-like state at 75 K. Mossbauer spectra at the paramagnetic range are doublets with a small quadrupole splitting and the isomer shift corresponding to a high spin Fe3+ state. Upon magnetic ordering, a coexistence of the paramagnetic doublet with a broadened magnetic sextet is observed indicating an inhomogeneous character of the magnetic transition. The hyperfine field of 350 kOe at 4.2 K is much lower than that observed for a high spin Fe3+ in oxides (510 kOe) which is attributed to covalence effects and a possible copper contribution to the effective magnetic moment of the compound.

In this article we focus on what discourse analysis brings to (im)politeness research. The paper begins by considering in more detail what is (im)politeness and why studying it in discourse is important. We then review some of the main approaches of discourse analysis that are employed in (im)politeness research. This is followed by two sample studies that illustrate some of the key challenges we face when analysing (im)politeness across different languages or different varieties of the same language. It can be seen that the shift in how (im)politeness is theorised over the past two decades has been accompanied by a move towards anchoring the analysis of (im)politeness in discourse. (Im)politeness is not something that should be attached to single utterances and its dynamic nature in discourse is what drives, in part, variability in evaluations of (im)politeness amongst users. It is also necessary to systematically examine not only whose understanding of politeness we are examining, but also on what grounds those understandings arise.

Opis:
Introduction and aim. Healthcare professionals including prescribers, pharmacists and nurses must have adequate knowledge of drug-drug interactions because they can cause toxicity, loss of efficacy, and side effects. This study was aimed to assess the respective roles of healthcare professionals in preventing drug-drug interactions by clinical interventions. Material and methods. This study was conducted at a Secondary Care Hospital of Pakistan in which total 1000 prescriptions were assessed for drug-drug interactions. Questionnaires and descriptive statistics were tools to assess the satisfaction of prescribers with pharmacists and their own prescribed medications before and after the clinical interventions. Modifications in medication therapies were done accordingly after the evaluation and acceptance of interventions. Results. The p-value was highly significant (p<0.05) which showed that the collaboration between healthcare professionals is necessary to avoid drug-drug interaction by clinical interventions. Acceptance rate of interventions was 77%. Clinical interventions are a useful tool in minimizing and preventing drug-drug interactions. The compliance of prescribers with their own prescribed medication regimens increased after clinical interventions. Conclusion. Prescribers, pharmacists and nurses have their respective roles in preventing drug-drug interactions and they must review the appropriateness of every medication order for clinical interventions.

Opis:
This paper presents the results of the study on structure and magnetic properties of the perovskite-type (BiFeO3)x-(BaTiO3)1-x solid solutions. The samples differing in the chemical composition (x = 0.9, 0.8, and 0.7) were produced according to the conventional solid-state sintering method from the mixture of powders. Moreover, three different variants of the fabrication process differing in the temperatures and soaking time were applied. The results of X-ray diffraction (XRD), Mössbauer spectroscopy (MS), and vibrating sample magnetometry (VSM) were collected and compared for the set of the investigated materials. The structural transformation from rhombohedral to cubic symmetry was observed for the samples with x = 0.7. With increasing of BaTiO3 concentration Mössbauer spectra become broadened refl ecting various confi gurations of atoms around 57Fe probes. Moreover, gradual decreasing of the average hyperfi ne magnetic fi eld and macroscopic magnetization were observed with x decreasing.

Opis:
In this work the compositional dependence of hyperfine interactions and magnetoelectric coupling in (BiFeO3)x-(BaTiO3)1–x solid solutions where x = 0.5–0.9 fabricated from commercial BaTiO3 in terms of the solid-state sintering method at various temperatures and over different time periods is described. In general, as the content of BaTiO3 increases, a decrease in the hyperfine magnetic field (Bhf) at 57Fe nuclei was observed. However, for samples exhibiting lower homogeneity in which the ions of Bi3+ and Fe3+ are replaced by Ba2+ and Ti4+ with lower probability, higher values of Bhf are obtained. For the sample where x = 0.6 that exhibits the coexistence of rhombohedral, regular and tetragonal phases, the highest value of the αME coefficient (3.57 mV/A) was observed, which is more than three times higher when compared to the hitherto published results.

Opis:
The room temperature Mössbauer spectra of 57Fe were measured for numerous dilute iron-based alloys Fe1-xDx (D = Al, Co, Cr, Mn, Mo, Ni, Os, Pt, Re, Ru, Ta, Ti, V, W, Zn), annealed at 1270 K for 2 h before the measurements. The spectra were analyzed using the Hesse–Rübartsch method in order to determine the mean hyperfi ne magnetic fi eld at the 57Fe nuclei as a function of concentration x of the minority component of the alloy. As the binary alloys are one-faze solid solutions of an element D in iron, a linear relationship between and x is observed. The result supports the suggestion that Mössbauer spectroscopy is a useful tool for the study of dissolution of different elements in iron.

Opis:
We present a synthesis of the mathematical model of a joint of a new generation multi-link surgical micromanipulator. A design of such a device involves finding solutions for several difficult problems which do not appear in classical 'large' robots.Aprototype in development has six links, and it is driven by brushless servomotors with planetary and worm gears, for which the total transmission ratio is above 10000:1. Most importantly, whole construction is covered by an antiseptic coating which substantially changes manipulator's dynamics. Because of the complicated form of the drive model with three-stage planetary gearings and coating interactions, control of such system is significantly different from control of a typical industrial robot. This paper presents a synthesis of the model of the joint, which can be used to design the control system. In this work the derived model is used to examine joint's properties and characteristics. Results are presented graphically and discussed.

Opis:
Introduction: In the daily practice of an otolaryngologist, we encounter cases where the symptoms are not the result of disease but result from pharmacotherapy. In the case of symptoms such as hearing loss, tinnitus, or dizziness, polytherapy may be used as the basis for their occurrence, which, due to the lack of rationality in combining drugs, leads to symptoms that the patient and the doctor very often interpret as a new disease syndrome. Aim: The aim of the study is to show and to raise awareness of the fact that the symptoms of hearing organ impairment are frequently drug-related and only a modification of the currently used pharmacotherapy is a rational procedure in such cases. Material: This paper describes 30 cases who developed side effects of polypharmacy in the form of hearing disorders, dizziness, and tinnitus. The causes of drug-related complications were discussed, as well as effective methods of their prevention.

Opis:
The Geodynamic Laboratory in Książ includes investigations of various kinds of geodynamic signals. Among others, we registered harmonic signals of the range 10-3 - 10-4 Hz. These signals had been found in the measurement series of the long water-tube (WT) tiltmeters. The discovered signals consist of two classes of harmonics associated with various kinds of phenomena. The first class of these signals belongs to viscoelastic vibrations of the Earth’s solid body, while the second class is produced possibly by the extremely long atmospheric infrasound waves. The signals of the vibrations of the Earth had been well recognized by the characteristic frequencies of the Earth’s free vibrations’ resonance, which occur mainly after strong earthquakes. The atmospheric pressure microvibrations affected the water level in the hydrodynamic systems of the WTs as a result of an inverse barometric effect. We observed that signals from both classes blend in the harmonics of similar frequencies and jointly affect the hydrodynamic systems of the WTs. We found that the amplitude of the secondclass signals strongly depends on the location of water-tube gauges inside the underground, while the amplitudes of the first-class signals are similar for all the gauges. These observations clearly indicate the atmospheric origin of the second class of registered signals.

Learning, popular knowledge and different cognitive patterns determine and select consciousness content. People, being subject to specific psychological mechanisms, determine quality and complexity of social relations and every day create from the beginning social reality. Knowledge about the ways people call the world and give new meaning to it as well as how they define the sense of their own activity are important and let better understand the phenomenon of organizational life and a special role of human as a creator of organizational culture.

Opis:
The investigation considers phase stabilization of ammonium nitrate for considerable extension of its application area including new generation of gas-generating compositions for airbag inflators. It was shown that alloys of ammonium nitrate with small amounts (2-10%) of some organic compounds can have no phase transitions or at least have only one instead of three ones in initial ammonium nitrate. The mostly effective as stabilizers are the compounds that have rather close crystallographic parameters. A strong donor-acceptor interaction between nitrate-anion and organic molecules are found. Using quantum-chemical calculations, X-ray analysis, X-ray phase analysis, UV- and IR-spectroscopy it was found a new ammonium nitrate phase state in its alloy with some organic additives. This state is stable in temperature range between -50 and +100 C.

Ternary Co-Fe-Ni alloys were prepared from the elemental powders by the mechanical alloying method. Structural properties and hyperfine interactions parameters were determined using X-ray diffraction and Mössbauer spectroscopy. X-ray diffraction proved that during milling Co-Fe-based solid solutions with b.c.c. lattice were formed in the case of Co40Fe40Ni20 and Co50Fe40Ni10 alloys, while for Co52Fe26Ni22 and Co65Fe23Ni12 compositions Co-Ni-based solid solutions with f.c.c. lattice were obtained. Mössbauer spectroscopy revealed similar values of the average hyperfine magnetic fields for all the alloys. These values corresponded to the different surroundings of 57Fe isotopes by Co, Fe and Ni atoms, depending on the chemical composition of the alloy. The possible atomic configurations around 57Fe isotopes were discussed on the basis of the local environment model under the assumption that only the first nearest neighbours contribute to the hyperfine magnetic field at 57Fe site.

Opis:
Criticality is considered as a fundamental category of production planning, maintenance process planning and management. The criticality assessment of machines and devices can be a structured set of activities allowing to identify failures which have the greatest potential impact on the company’s business goals. It can be also used to define maintenance strategies, investment strategies and development plans, assisting the company in prioritizing their allocations of financial resources to those machines and devices that are critical in accordance with the predefined business criteria. In a criticality assessment process many different and interacting criteria have to be taken into consideration, despite the fact that there is a high level of uncertainty related to various parameters. In addition, not all assessment criteria are equally important. Therefore, it is necessary to determine the weight of each criterion taking into account different requirements of machine criticality process stakeholders. That is why a novel model of a machine criticality assessment is proposed in this paper. The model extends the existing methods of assessing machines criticality, taking into account not only the importance of machine criticality assessment criteria, but also possible interactions between them.

Określono wartości parametrów układu dla ruchu postępowego i obrotowego zderzających się ciał, umożliwiających wystąpienie tzw. oddziaływań torsyjnych. Zaproponowano układ pomiarowy do określenia tego zjawiska na bazie przyspieszeniomierzy i giroskopów prędkościowych.
The paper has been intended to present a new mathematical formula (given by Russian physicist Prof. Szypow) to describe flat collisions with rotation in the form of equations of momentum and moment of momentum within a dynamic reference frame. What has been discussed is a mathematical model generated at ITWL to describe collisions of rotating bodies. Simulation-effected results gained with the Matlab-Simulink are presented. Evaluated are parameters of the reference frame for both translatory and rotary motion of colliding bodies, which enable the so-called torsional interactions. Proposed is a measuring system to define this phenomenon using accelerometers and rate giroscopes.

Opis:
This article contributes to our understanding of how boundary work is practiced in healthcare settings. Previous studies have shown how boundaries are constantly changing, multiple, and co-existing, and can also be relatively stable cognitive and social distinctions between individuals and groups. In highly specialized, knowledge-intensive organizations such as healthcare organizations, organizational, professional, and disciplinary boundaries mark the formal structure and division of work. Collaboration and coordination across these boundaries are essential to minimizing gaps in patient care, but also may be challenging to achieve in practice. By drawing on data from an ethnographic study of two hospital wards, this article investigates practices of cross-disciplinary and professional collaboration and adds to our knowledge of how this kind of boundary work is produced in context. Moreover, it adds to existing boundary literature by exploring the fast-paced, situational, micro-interactions in which boundaries are drawn, maintained, and dissolved. These mundane, brief exchanges are essential to the practice of collaboration through boundary work. I consider the implications of these findings for boundary theory and boundaries in healthcare and other related settings.

Opis:
Flotation and adsorption characteristics of the most commonly used cationic and anionic collectors with high grade orthoclase were investigated through the electrokinetic potential measurement, microflotation, Fourier transform infrared spectroscopy (FTIR) and atomic force microscopy (AFM) studies. According to the obtained results, orthoclase had high flotation recovery with amine and oleic acid based (OAB) collector at certain pH ranges no flotation response was observed with petroleum sulfonate at different pHs. In contrast to the flotation recovery differences, the electrokinetic potential measurements, FTIR and AFM analyses presented similar adsorption characteristics for all collectors. The results of electrokinetic potential tests showed that amine had a strong influence on the zeta potential of orthoclase. While amine turned the zeta potentials of orthoclase from negative to positive, sulfonate and OAB collector provided slightly more negative zeta potentials at certain pHs. In the case of FTIR and AFM analyses, each collector-treated orthoclase (CTO) sample displayed similar characteristic FTIR bands of CH2 group and micro topographical collector coated patches with different intensities. However, the interactions of each collector with orthoclase surfaces were altered by rinsing with acetone indicating that the interactions were mostly through the electrostatic forces and/or hydrogen bonding.

Opis:
Flotacja jest jedną z najefektywniejszych metod wstępnej identyfikacji oddziaływań białko-błony lipidowe. W większości przypadków wykorzystuje się w niej małe jednowarstwowe pęcherzyki lipidowe, które służą jako modele błonowe i nie wymagają dodatkowych nośników, takich jak membrany czy nanocząstki polimerowe, które są często używane w innych metodach mających na celu identyfikację oddziaływań białkolipid. W poniższej pracy prezentujemy wyniki uzyskane podczas badań oddziaływań kwasu fosfatydowego i syndapiny. Omawiamy także niektóre techniczne aspekty metody, kładąc nacisk na to jak małe zmiany w warunkach metody mogą wpłynąć na otrzymywane wyniki.
Flotation is one of the best method for preliminary identification of protein-lipid interactions. In most widely used approach it utilizes large unilamellar vesicles, that are excellent models of freestanding membranes and do not require any additional components, like solid supports or beads that are needed in other methods commonly used for protein-lipid binding studies. Here we present results obtained during our studies on phosphatidic acid - syndapin interactions and discuss some technical aspects of this method underlying how relatively small changes in the conditions can influence the results.

Opis:
In this work the hyperfine interactions in (BiFeO3)x-(BaTiO3)1-x solid solutions with relation to their structural properties have been investigated. X-ray diffraction, Mössbauer spectroscopy and magnetoelectric effect measurements have been used for studies of sintered (BiFeO3)x-(BaTiO3)1-x solid solutions with x = 0.9, 0.8 and 0.7. With increasing contents of BaTiO3, the structural transformation from rhombohedral to cubic was observed. The weakening of the hyperfine magnetic fields accompanied by this transformation. On the other hand, the increasing amount of BaTiO3 caused an increase of the magnetoelectric effect.

Opis:
In spite of the important recent advances in the field of low-energy electron interactions with atoms and molecules, there still exist fundamental needs and challenges, some of which are generic in their basic and applied significance. These include measurements of cross sections for a number of fundamental low-energy electron–ground-state molecule interaction processes such as vibrational excitation (direct and indirect) and dissociation into neutral fragments, studies of low-energy electron–excited molecule interactions, investigations of low-energy electron interactions with radicals and transient species, and measurements of electron energy losses in electron–molecule collision processes. They also include studies for linking of knowledge on isolated electron–molecule interactions to that in the condensed phases of matter, and the systematic and quantitative exploration of the interactions of low-energy electrons with molecular and macromolecular biological structures.

Opis:
Abstract Information about the space-time evolution of colliding nuclei can be extracted correlating particles emitted from nuclear collisions. The high density of particles produced in the STAR experiment allows the measurement of non-identical strange particle correlations. Due to the absence of Coulomb interaction, p-Lambda and p Lambda- systems are more sensitive to the source size than p-p pairs. Strong interaction potential has been studied using p-Lambda, and for the first time, p Lambda pairs. The experimental correlation functions have been described in the frame of a model based on the p-n interaction. The first preliminary measurement of pi-Teta correlations has been performed, allowing to extract information about the freeze-out time and the space-time asymmetries in particle emission closely related to the transverse radial expansion and decay of resonances.

Opis:
Twelve teachers of English representing three groups of different seniority: pre-service, freshmen and senior responded to the anxiety questionnaire to establish the relationship between the anxiety level and their teaching experience. The senior group is reported to have experienced less anxiety than other teachers. Some influential factors which determine a level of this specific anxiety were identified, for example expectations towards their work, autonomy in taking deci- sions, interactions with authorities, superiors and students. Finally, the article discusses practical ways of coping with teacher anxiety in a classroom.

Opis:
This multi-institutional study of undergraduate and graduate students enrolled in online degree programs explored student perceptions of required student-to-student interactions. Using a semi-structured interview methodology, thirty-three students participated in the study. While all of the students had experience with the required discussion board interactions of posting and responding, a majority of the students reported experience with other types of required student-to-student interactions including group projects, group presentations, peer reviews, and, for a few, discussions within the required synchronous sessions. The findings indicate that while most value the concept of peer-to-peer interaction in online courses, many found the required assignments lacking in authenticity and not a good use of their time. Some students reported satisfaction with one or more of the requirements such as small group assignments when time was allowed for coordination, small group discussions, and selected discussion board posts. The students valued the interactions most when those interactions were relevant to their careers. These findings encourage taking the demographic realities of students studying online into consideration when incorporating student-to-student interactions into courses. Many have family and other obligations, so they are particularly sensitive to work that appears to be trivial or unnecessary. Hence, learning elements such as peer-to-peer interactions should be incorporated into courses intentionally and with purpose so that the interactions do not appear to be busy-work or checking an interaction box.

Opis:
Nifuroxazide is a popular chemotherapeutic agent, that is widely used in Poland in acute and chronic bacterial diarrhea treatment. It is available in pharmacies as over-the-counter tablets for adults and a suspension on prescription for children. The aim of the study was to assess the safety of nifuroxazide therapy. Adverse reaction reports from the Regional Pharmacovigilance Center in Wroclaw, the pharmaceutical company PPF Hasco-Lek, and VigiAccess and EudraVigilance databases were analyzed. Based on the analysis of the data collected from the above sources, nifuroxazide have shown a high therapeutic value in the gastrointestinal tract infections, maintaining high safety of usage at the same time. The number of drug application adverse reactions in Poland is not so high primarily due to high safety profile and low patient awareness of the possibility of reporting drug side effects.

Opis:
The article draws attention to the potential significance of Herbert Blumer’s heritage in the sociological analysis of the issues with which modern democracy has to deal. It aims to strengthen that current of interpretation pertaining to symbolic interactionism which opposes the widespread tendency to consider it as amicrosociological orientation. The article emphasizesmedium-range phenomena-in other words, mesosociological problems of organizations, interest groups and social movements. Blumer helped George H. Mead’s ideas, including the basic concept of the self, find a fuller application in sociology. To properly evaluate Blumer’s achievements, one should consider him as a researcher of the changes occurring in modern societies in general. He emphasized the existence of a constant process of defining and redefining social institutions, and thus, the role of civic agency-in other words, ultimately, of the reflexive self. In Blumer’s conceptions of symbolic interaction, joint action and negotiated order one may see an elaboration of the interactional order of the democratic society.

Opis:
The paper presents a numerical analysis of the thermal damage process taking place in biological tissue containing a blood vessel during laser irradiation. The internal heat source resulting from laser irradiation based on the solution of the optical diffusion equation is taken into account. The investigation was concerned with the influence of tissue denaturation and oxygen content in blood on temperature distribution. The analysis of oxygen transport to the tissue is treated as a part of the analysis of thermal damage processes. At the stage of numerical computations, the boundary element method and the finite difference method were used.

Opis:
Red basil (Ocimum basilicum L.) cv. Red Rubin was cultivated in model pot experiment in the soil amended by arsenic, cadmium and lead solutions in stepwise concentrations representing the soil concentration levels of former mining area in the vicinity of Příbram, Czech Republic. The element levels added to the soil reached up to 40 mg Cd, 100 mg As, and 2000 mg Pb per kg of soil. Moreover, essential macro-and microelements as well as cyanidine contents were investigated to assess their potential interactions with the risk elements. The extractable element portions in soils determined at the end of vegetation period differed according to the individual elements. Whereas the plant-available (extractable with 0.11M CH3COOH) content of Cd represented 70-100% of the added Cd, the mobile portion of Pb did not exceed 1%. The risk element content in plants reflected the increasing element contents in soil. The dominant element portions remained in plant roots indicating the limited translocation ability of risk elements to the aboveground biomass of this plant species. Although the risk element contents in amended plants significantly increased, no visible symptoms of phytotoxicity occurred. However, the effect of enhanced risk element contents on the essential element uptake was assessed. Considering inter-element relationships, elevated sulphur levels were seen in amended plants, indicating its possible role of phytochelatin synthesis in the plants. Moreover, the molybdenum contents in plant biomass dropped down with increasing risk element uptake by plants confirming As-Mo and Cd-Mo antagonism. The increasing content of cyanidine in the plant biomass confirmed possible role of anthocyanins in detoxification mechanism of risk element contaminated plants and suggested the importance of anthocyanin pigments for risk element tolerance of plants growing in contaminated areas.
