Abstract
In this work the synthesis of hercynite from Fe2O3 and Al2O3 powders was carried out by arc-melting method under the protective argon atmosphere. The obtained material was characterized with the use of powder X-ray diffractometry (XRD) and Mössbauer spectroscopy (MS). A Mössbauer effect in hercynite obtained by the arc-melting method indicated the cations distribution in the spinel structure among the tetrahedral and octahedral interstices. The presence of Fe2+ ions was detected in both tetrahedral and octahedral sites while Fe3+ ions occupied only the octahedral interstices. The approximate formula of the obtained iron-aluminate spinel was as follows (Fe2+
0.77Al3+
0.23) (Fe3+
0.07Fe2+
0.05Al0.88)2O4.

Abstract
Mössbauer investigations, in association with density functional theory (DFT) calculations, have been conducted for the molecular and electronic structures of iron (III) [tetrakis (pentafluorophenyl)] porphyrin chloride [(F20TPP)Fe:Cl], as a Fe(III)-tetraphenylporphyrin complex containing chloride axial ligand and substituted hydrogen atoms by fluorine ones in the four phenyl rings, in comparison with its fluorine unsubstituted analogue [(TPP)Fe:Cl]. It was found that the parameters of Mössbauer spectra of both complexes are close to one another, and correspond to the high-spin state of Fe(III) ions, but they show the different temperature dependence and the quadrupole doublets in Mössbauer spectra show different asymmetry at low temperatures. Results of DFT calculations are analyzed in the light of catalytic activity of the halogenated complex.

Abstract
Magnetic and Mössbauer measurements were performed for MnNi0.85Fe0.15Ge. The Mössbauer data indicate that Fe atoms in MnNi0.85Fe0.15Ge are randomly distributed over two types of metal sites in hexagonal structure. At 77 K, the hyperfine magnetic fields at Fe located in different crystal sites have similar values of about 12.7 and 12.3 T. The random site distribution of the iron atoms in the non-magnetic hexagonal phase at high temperatures is confirmed by the theoretical calculations in fully relativistic Korringa –Kohn –Rostoker (KKR) method.

The Origin of the Term Handicap in Games and Sports – History of a Concept
Authors: Hansen Jørn 
Published: May 2015

Abstract
Words and concepts may change in time, and this has certainly been the case with the term handicap. From the establishment of modern sports in the middle of the 19th century and up until the middle of the 20th century, handicap had an entirely different meaning within sports. Thus, handicap was understood as a disadvantage imposed on talented contestants to make the competition more equal in sports. Later the term handicap became much closer related to the concepts invalid and crippled than to concept originally employed within sports, With the gradual introduction of the welfare state measures to the political agenda the politicians in Denmark also started to take an interest in invalids and cripples and in 1925 the National Association of the Crippled and Maimed was founded. By the end of the 20 century the term crippled was seen by many as outdated and in 1988 the name was changed to the Danish Association for the Disabled (Dansk Handicap Forbund) and already in 1971 this organization helped to found The Danish Disabled Sports Association (Dansk Handicap Idræts-Forbund). The article tells the story of how the concept of handicap, which originally was an aim to provide equal opportunities, today has become a synonym for disability, while in the Paralympics and competitive disability sports, the original sports term handicap has been replaced by classification.
Disabled People in Play.Toward an Existential and Differential Phenomenology of Moving with Dis-Ease
Authors: Eichberg Henning 
Published: May 2015

Abstract
Disability has become an increasingly important field of investment for modern welfare policy-visible in architecture for wheelchair users as well as in budgets for health care. This documents a gain in solidarity, but it implies also some challenges of practical and philosophical character. Play and games (of, for, and with disabled people) make these challenges bodily. These challenges will here be explored in three steps.
In the first step, we discover the paradoxes of equality and categorization, normalization and deviance in the understanding of disability. Ableism, a negative view on disability, is just around the corner. The Paralympic sports for disabled people make this visible. However, play with disabled people shows alternative ways. And it calls to our attention how little we know, so far, about how disabled people play.
The second step leads to an existential phenomenology of disablement. Sport and play make visible to what degree the building of “handicap” is a cultural achievement. All human beings are born disabled and finally die disabled-and inbetween they create hindrances to make life dis-eased. Dis-ease is a human condition.
However, and this is an important third step, disablement and dis-eased life are not just one, but highly differentiated. These differences are relevant for political practice and have to be recognized. Attention to differences opens up a differential phenomenology of disablement and of disabled people in play-as a basis for politics of recognition.
Inclusion of Outsiders Through Sport
Authors: Fehsenfeld Michael 
Published: May 2015

Abstract
Social work strategy is increasingly applying sports and physical activity programs as a vehicle for the social inclusion of outsiders. The underlying assumption is that interactions between diverse social groups generate social capital, which can potentially function as a social lever for socially disadvantaged groups. Knowledge about how and when this levering process occurs is, however, insufficient. The generation and acquisition of social capital requires adequate qualities in the relationship between social entities. Hence, meticulous research is essential to expound on the mechanisms and circumstances under which the socially disadvantaged can benefit from social capital generated through sports and physical activity. The article is primarily based on qualitative interviews with different groups of socially disadvantaged people. The interviews were conducted as part of a large-scale investigation of participation in sports in socially deprived neighborhoods. Subsequently, the findings from the qualitative interviews were triangulated with findings from an assessment of documentation and evaluation reports covering about 200 projects, and findings from a scientific literature review. The findings suggest that strategies aiming at social inclusion through sports and physical activities need to take social context into consideration
The Lived Experiences of Participating in Physical Activity among Young People with Mental Health Problems. A Recovery-Oriented Perspective
Authors: Staal Anna , Jespersen Ejgil 
Published: May 2015

Abstract
There is a growing understanding that psychiatric treatment is more than psychotherapy and medication, and that people themselves can be active in preventing and handling mental health problems. This brings non-medical solutions into play. Physical activity (in terms of exercise, sport, and fitness) becomes an important contribution in this particular context. The perceived mental and physical benefits of physical activity (both preventative and therapeutic) for people experiencing mental health problems are well documented. Typically, this kind of research focuses narrowly on “size of effect” or “most successful type of intervention” or “exercise versus other treatment.” Less research has explored the lived experience of physical activity and the meaning and relevance it has for individuals in their everyday lives. This article suggests that sport and exercise can play a valuable role in and contribute to the recovery process for young people with mental health problems. Results from an evaluation study of a developmental project in Denmark shows how physical activity affects a person‟s lived experiences, relationships, and pursuits. The findings is discussed in relation to the concept of recovery, especially focusing on exercise as a form of self-care strategy, as an opportunity to create social relationships, and as a way to become part of a meaningful social activity.
The Embodied Nature of Autistic Learning: Implications for Physical Education
Authors: Jespersen Ejgil , He Jing 
Published: May 2015

Abstract
Autism spectrum disorder (ASD) and learning difficulties are difficult to separate in clinic manifestations and diagnoses. By taking learning as being-in-the-world, this article considers the embodied nature of autistic learning and urges its importance for understanding the phenomenological core of ASD. We begin by arguing that three mainstream contemporary ASD theories are inherently limited in offering an adequate account of autistic learning due to the disembodied ontology inscribed within them. Then, we provide an understanding of learning guided by the subjective dynamics of experience. Instead of having a disembodied and individualistic point of view, we suggest that autistic learning has an embodied nature. The “inappropriate” or “abnormal” affections and behaviors in the autistic experience of learning may actually be inherently meaningful for individuals with ASD. They strive to make sense of some basic disturbances and re-establish some form of coherence with the world, though this may only be possible in the form of delusions or autistic withdrawals. Finally, we explore the relationship between autistic learning and physical education and suggest in particular how spontaneous imitation can boost the development of children with ASD. We conclude that the application of implicit learning strategies in playful settings and the reduction of explicit strategies based upon intellectual reasoning rather than bodily reciprocity should be encouraged in the process of autistic learning.

Published: May 2015

Abstract
The aim of this paper is a mathematical description of algorithm for controlled assembly of incinerated batch of waste. The basis for formation of batch is selected parameters of incinerated waste as its calorific value or content of pollutants or the combination of both. The numerical model will allow, based on selected criteria, to compile batch of wastes which continuously follows the previous batch, which is a prerequisite for optimized operation of incinerator. The model was prepared as for waste storage in containers, as well as for waste storage in continuously refilled boxes. The mathematical model was developed into the computer program and its functionality was verified either by practical measurements or by numerical simulations. The proposed model can be used in incinerators for hazardous and municipal waste.
The effect of preparation method on the performance of PtSn/Al2O3 catalysts for acetic acid hydrogenation
Authors: Zhang Ke , Zhang Haitao , Ma Hongfang , Ying Weiyong , Fang Dingye 
Published: May 2015

Abstract
PtSn/Al2O3 catalysts with a given loading of 1 wt% Pt and 1 wt% Sn were prepared by co-impregnation or successive impregnation with aqueous solutions of Pt, Sn precursors and a commercial alumina. The catalysts were characterized by N2 adsorption, H2-TPR (H2 temperature-programmed reduction), H2-pulse chemisorption, XPS (X-ray photoelectron spectroscopy) and CO-FTIR (Fourier transform infrared spectroscopy), and tested in the hydrogenation of acetic acid. The results showed that the preparation method affected both the chemical properties and their performance in the hydrogenation of acetic acid. Sn enrichment on the catalysts surface was observed on the co-impregnated catalyst and catalyst in which the Pt precursor had been loaded first. It was found that the modification of Pt was a function of the sequence of Sn addition as revealed by CO-FTIR. Co-impregnated catalyst showed the highest activity and ethanol selectivity.
A novel approach for calculating packed column height based on new correlation of mass transfer coefficient
Authors: Rahbar-Kelishami Ahmad , Bahmanyar Hossein , Hajamini Zahra 
Published: May 2015

Abstract
The calculation of column’s height plays an important role in packed columns precise design. This research is based on experimentally measurement of mass transfer coefficients in different heights of packed column to predict its height. The objective of presented work is to introduce a novel conceptual method to predict column height via new correlation for mass transfer coefficient. As the mass transfer coefficient is decreased with increase of column height, the HTU’s are not constant figures along the column so this new approach is called increasing HTU’s. The results of the proposed idea were compared with other correlations and the conventional method i.e. constant HTU’s. Since the results are in very good agreement with experimental data comparing to conventional method, it seems this approach can be a turning point in design of all differential columns like packed columns. Making use of this method is suggested for design of differential columns.

Published: May 2015

Abstract
The improved one-pot synthesis of dimethyl carbonate and propylene glycol from propylene oxide, supercritical carbon dioxide, and methanol with potassium bicarbonate as the catalyst has been reported in this paper. As far as we know, it is the first time to use potassium bicarbonate only as the catalyst in the production process which is simple and cheap. Satisfactory conversion rate of propylene oxide and yield of the products could be achieved at the optimized conditions with quite a small amount of by-products. Our new method offers an attractive choice for the production of dimethyl carbonate in large-scale industry efficiently and environmental friendly.
Biosorption of lead(II), zinc(II) and nickel(II) from industrial wastewater by Stenotrophomonas maltophilia and Bacillus subtilis
Authors: Wierzba Sławomir 
Published: May 2015

Abstract
The biosorption of Pb(II), Zn(II) and Ni(II) from industrial wastewater using Stenotrophomonas maltophilia and Bacillus subtilis was investigated under various experimental conditions regarding pH, metal concentration and contact time. The optimum pH values for the biosorption of the three metals were in the range 5.0-6.0, while the optimal contact time for the two bacterial species was 30 min. Experimental data was analyzed using Langmuir and Freundlich isotherms; the former had a better fit for the biosorption of Pb(II), Zn(II) and Ni(II). The maximum adsorption uptakes (qmax) of the three metals calculated from the Langmuir biosorption equation for S. maltophilia were 133.3, 47.8 and 54.3 for Pb(II), Zn(II) and Ni(II), respectively, and for B. subtilis were 166.7, 49.7 and 57.8 mg/g, respectively. B. subtilis biomass was more favorable for the biosorption of Pb (II) and Ni (II), while S. maltophilia was more useful for the biosorption of Zn (II).
Super phosphoric acid catalyzed esterification of Palm Fatty Acid Distillate for biodiesel production: physicochemical parameters and kinetics
Authors: Metre Anand V. , Nath Kaushik 
Published: May 2015

Abstract
In the present study the esterification of palm fatty acid distillate (PFAD), a by-product from palm oil industry, in the presence of super phosphoric acid (SPA) catalyst was studied. The effects of various physico-chemical parameters such as temperature, PFAD to methanol molar ratio and amount of catalyst on the conversion of biodiesel were investigated. The percent conversion of FFA and properties of the biodiesel were determined following standard methodologies. Percent conversion of biodiesel was found to increase with the increase in PFAD to methanol molar ratio and at 1:12 molar ratio and 70°C temperature 95% conversion was achieved. Thermodynamic parameters were also evaluated in terms of Gibbs free energy, enthalpy and entropy at different molar ratio and temperatures. Both pseudo first and second order irreversible kinetics were applied to a wide range of experimental data. However, according to regression coefficient (R2) the second order described better experimental behavior of kinetic data.

Published: May 2015

Abstract

Introduction. Transplantation surgery, involving transplantation of cells, tissues and organs, constitutes a common medical practice that saves the lives of a great number of patients.

Aim. The purpose of the present paper is to provide a comparative analysis of the legal regulations regarding transplantation that are in practice inside three European countries: Poland and Germany - EU Member States - and Switzerland - a non-EU state. The considerations made herein are meant to find an answer to the question whether the provisions of law regarding transplantation in the specified European countries regulate the legal situation of the donor and the recipient in a similar manner.

Material and methods. The paper is based on the following source documents: The Cell, Tissue and Organ Recovery, Storage and Transplantation Act of July 1, 2005; The Act on Donation, Recovery and Transplantation of Organs and Tissues of November 5, 1997 (Transplantation Act - TPG); Federal Act on Transplantation of Organs, Tissues and Cells of October 8, 2004. In our work, we applied two methods, the first being comparative, and the second being dogmatic-legal. The latter consists of analyzing the provisions regarding transplantation as found within the three selected European countries.

Results and Discussion. Under Polish, German and Swiss law alike, the recovery of cells, tissues and organs is allowed from an adult, who, under the Polish and German Acts, has full capacity to enter into legal transactions, and who, under the Swiss Act - is an adult who is mentally competent. Of note is that a minor might only be a donor in ex vivo transplantation provided that precisely specified requirements are met. Of additional note is that, under the German and Swiss Acts, recovery of tissues and organs from a human cadaver donor is allowed only if this person gave consent for such recovery prior to their death; under the Polish Act, this is allowed unless the deceased person expressed their objection when alive.

Conclusion. As far as ex vivo transplantation is concerned, the legal solutions regarding transplantation in Poland, Germany and Switzerland regulate the legal situation of the donor and the recipient of a transplant in a similar way, although there are a few significant differences. As for ex mortuo transplantations - the legal solutions applied in each country greatly differ.

Abstract

Introduction. Cardiovascular diseases are the leading cause of premature death in Europe. In Poland, the percentage mortality is 2, 5 times higher than in Western European countries.

Aim. To assess patients' knowledge of the need for diet and physical activity after cardiac surgery. Material and methods. The study involved a group of 150 patients after cardiac surgery. The research was conducted at the Department of Cardiac and Vascular Surgery, University Clinical Centre in Gdansk. The study used a questionnaire of our own design.

Results. Over half of the respondents stated that they had an average amount of knowledge with regard to healthy eating, while one in four had a less than average level of knowledge, and 16% opined that they had a superior knowledge of the same. These results are dependent on age and degree of formal education, and to adherence to dietary recommendations of gender, to financial situation and marital status. With regard to average dietary adherence, more women than men properly identified products harmful to human health. These last results bore little correlation to place of residence or degree of formal education. In addition, slightly more than half of the respondents (55.3%) practiced some sort of physical activity, but up 44.7% does not do any. More active were women and younger people (of both sexes), and those with higher degrees of formal education.

Conclusions. Knowledge of patients with regard to diet after cardiac surgery is dependent on age and degree of formal education, and to adherence to dietary recommendations of gender, to financial situation and marital status. However, formal education and place of residence does not have a significant impact on the level of knowledge of products that are harmful to human health and behavior. Both sex, place of residence and degree of formal education have an impact on level of physical activity in general, as well as on its individual manifestations. More active are women, younger people and those with higher formal education.
