The Business of Sport, Sledging and the Corruption of Play – an Interpretation through a Huizingian-Bourdieu Lens
Authors: Duncan Samuel Keith
Published: February 2019

Using a combined Huizingian-Bourdieu framework, this paper analyses the significance of sport’s transformation into a business and how the prevailing business structure that defines professional sport has influenced the ‘lived experience’ of those playing at sport’s elite level. Furthermore, this paper highlights how the actions of players, coaches and other participants serve to reinforce, legitimise and normalise the business characteristics of sport’s dominant business structure.

Importantly, this paper illuminates how the professionalization of sport corrupts the act of playing and indeed gives rise to play tactics, such as ‘sledging’, which both reflects the increased seriousness of sport and, in its very execution, further reinforces the dominant business structures of professional sport, all the while corrupting the essence of sport – play.

In doing so we are challenged to consider how society’s fields could be different in structure, and in the ‘lived experience’ within the field.
Discussing the Scientific Evidence Generation and Psychological Research Methods in Postmodern Societies
Authors: Sesé Albert
Published: February 2019

Evidence generation by current Social and Health Sciences is coping with some important barriers that difficult credibility of scientific products. Information and communication technologies have a strong impact over social relationships in our postmodern societies. The incidence of post-truth in our context is generating a pernicious relativism, far from contrasting the information veracity. The aim of this paper is to analyze and discuss the challenges of research methods and statistical models, more specifically for Psychological research, taking into account the impact of novel techniques as big data and virtual reality. Special attention is also devoted to the discussion about statistical shortcomings of psychological research and to the reproducibility problem. Finally, some potential solutions are proposed to be applied in order to improve the quality of scientific evidence.

Authors: Zysberg Leehu
Published: February 2019

The summer of 2011 has seen the first mass-scale social protest in Israel in its 70 years of existence. This social wave that shook the country, showed unique characteristics a-typical of most social and political uprisings, that go largely unexplained by social theories of social change and crowd psychology. In this article I am analyzing published reports of the social protest of 2011, and draw the analogy with the concept of ‘Agoral Gathering’ that may account for these events and support discussion of their aftermath.

Published: February 2019

The new Ion Beam Centre (IBC) equipped with 6 MV tandem ion accelerator and 500 kV ion implanter systems was built at the Slovak University of Technology, Faculty of Materials Science and Technology (STU MTF). The facility provides Ion Beam Modification of Materials (IBMM) and Ion Beam Analysis (IBA), which includes Rutherford Backscattering Spectrometry (RBS), Particle Induced X-ray Analysis (PIXE), Elastic Recoil Spectrometry (ERDA) and Nuclear Reaction Analysis (NRA). Presented are selected experimental procedures carried out in the IBC during the first year of operation. They present examples of a typical IBA performed, such as thin film characterisation in nm to tens of µm range, elemental depth profiles and sensitivity to the light elements enhancement by non-Rutherford cross-section regime application along with the crystalline sample channelling spectra and boron content measurement.
On the Problem of the Ion Energy Loss in Thin Absorbers
Authors: Minárik Stanislav , Riedlmajer Róbert
Published: February 2019

Exact determination of energy loss of ion in materials is still a non-trivial task because of relatively complicated changes of the ion`s stopping power S(E) during transport of the probing ion inside the material structure. Energy loss of ion in the material structure always depends on the current value of continually decreasing energy of the ion, indeed. A purely theoretical approach can be applied to the energy loss calculation in some typical cases. Average energy loss of ion can be determined by means of the Bethe-Bloch analytical theory (1-6) (in high velocity region) and the Lindhard-Scharff-Schiøtt (LSS) theory (7-10) (in low velocity region). Currently, there is no acceptable exact theory to determine the energy loss of ion in intermediate-velocity region (11) and experimental data must be used in that case. Basically, only a finite number of discrete experimental data is always available. Therefore, if the problem how much energy the projectile ion loses in a certain distance travelled is solved, the modelling of function S(E) based on some acceptable assumptions must be applied.

In this contribution, we present the energy loss calculations in intermediate-velocity region of ion based on linear interpolation of experimental data. Calculation was carried out for a kapton foil using the data taken from Ziegler, Biersack (12). Energy values of an ion along its trajectory inside the foil were found, and the mean projected range of ion penetrating into the foil was calculated. Finally, the energy resolution was evaluated taking into account straggling provided that the foil is used as an absorber in the ERDA experiment.

Published: February 2019

The trace element analysis system is presented using Proton Induced X-ray Emission (PIXE) analysis at a new Ion Beam Centre in Trnava. Standard PIXE system dedicated to the measurement of thick solid samples was extended by a new application for trace element analysis in aerosol samples. The sample holder was modified with respect to the dimensions of the aerosol filters, and a new sample holder and a Faraday cup (FC) were made. The first results of the PIXE aerosol analysis are presented in this paper. Furthermore, the geometric efficiency of the detection system was verified using 55Fe radioactive source emitting monoenergetic Mn X-ray lines. The measured data were compared with the Monte Carlo simulations regarding/disregarding the X-ray attenuation.

Authors: Drienovský Marián , Trnková Lýdia Rízeková , Čička Roman , Priputen Pavol , Pekarčíková Marcela , Janovec Jozef
Published: February 2019

The influence of increased Cu and Ag contents on the microstructure evolution in the utilized Sn-0.3Ag-0.7Cu (wt. %) solder was studied. The utilized solder was exploited in the wave soldering process at the temperatures of about 260 °C for several days. The samples investigation involved the differential scanning calorimetry, the scanning electron microscopy including the energy dispersive X-ray spectroscopy, and the X-ray diffraction techniques. To predict phase equilibria at various temperatures and temperature dependences of heat capacity, the Thermo-Calc software and the COST531 lead-free solder database were used. The original and the utilized solders were found to be very similar regarding the phase occurrence, but slightly differ from one another in microstructure evolution due to higher bulk contents of Cu in the latter solder. The obtained results contribute to both the better understanding of the microstructure evolution in low-silver Sn-Ag-Cu solders and the determination of compositional limits for those solders used in the wave soldering process.

Authors: Laslavíková Jana , Calvo Beatriz Gómez-Pablos
Published: February 2019

This study looks at the work of Spanish playwright José Echegaray and the circumstances of his domestication on the European theatre stages at the turn of the 20th century. One of his most important works, El gran Galeoto55, arrived in Bratislava in 1889, only one year after its premiere in Vienna and three years after the opening of the new building of the Bratislava City Theatre. The premiere of the work, translated into German and in a theatrical adaptation from Paul Lindau’s pen named Galeotto took place around the same time as the premiere of the work Ralph William from the domestic author Josef Julian, which thanks to a similar theme was perceived as «Bratislava’s Galeotto».

Contribution of Slovak Directors to the Profile of the Czech Opera Theatre After 1993
Authors: Mojžišová Michaela
Published: February 2019

The ambition of the survey study, which maps the work of Slovak directors in Czech opera theatres after 1993, is to identify the number of Slovak creators in the opera-theatre discourse of the very closely connected countries in terms of culture and history while at the same time adding the professional biographies of Slovak artists – who are little known and reflected upon in their homeland – and parts of their works. The author concludes that the split of the Czechoslovak Republic and the subsequent creation of separate Czech and Slovak Republics did not have an adverse effect on the mutual contacts of our opera cultures. At present, we even enjoy intensified co-operation in both directions. The nonjudgmental attitude of Czech theatres towards the influence of Slovak film directors in the Czech Republic is clear: not only credible creators (Marián Chudovský), but also representatives of the younger generation of opera directors (Andrea Hlinková) and renowned drama directors with previous opera experience (Martin Huba, Roman Polák), as well as creators who had not yet worked on the opera scene at home (Martin Čičvák, Sláva Daubnerová) were presented with an opportunity to contribute. Despite the fact that their works represented the enrichment of the Czech opera-theatre, the Slovak director with the most significant contribution to the Czech opera theatre remains Jozef Bednárik, even two decades later.
Possiblities and Limitations of Translation of Slovak Drama Into Polish Culture
Authors: Spyrka Lucyna
Published: February 2019

The Polish and Slovak languages, as well as Polish and Slovak cultures, are considered very similar, so it would initially appear that there would be no obstacles limiting the possibilities of translating Slovak drama into Polish. It turns out however, that Slovak drama is not often translated into Polish. Older translations that were presented in Polish theatres were rarely followed in the press, and today they have been forgotten. On the contrary, current translations are published far more often than staged. The presented study evaluates this situation as a result of several limiting factors. In addition to the political conditions of cultural exchange and the manner in which publishers and theatres operate in Poland, there is also a linguistic closeness that negatively impacts on the quality of translations, as well as the stereotype of Polish and Slovak cultural proximity, which limits the interest of Polish audiences in Slovak drama.

Published: February 2019

Introduction Efficient cleaning and canal design present a basic precondition for successful endodontic treatment. The aim of this study was to evaluate, using SEM analysis, the efficacy of cleaning the apical third of the canal with one instrument in both reciprocating motion and full rotation systems.

Materials and methods Thirty (30) single-rooted teeth (upper incisors), extracted due to periodontal reasons, were used and selected in 2 groups. In the group 1, instrumentation was done with a single instrument UNICONE with reciprocal movements (MEDIN, Czech Republic), while in the group 2, a single instrument XPS endo SHAPER (XPS) (FKG, Dentaire, Swiss) with full rotation was used. 2% solution of NaOCl and 17% EDTA solution were used as irrigation agents in both groups. SEM analysis of smear layer in the apical third was done at standard magnification of 1000x and presented on a scale of 1-5.

Results showed mostly clean canal walls and no smear layer in the apical region in both tested groups. Canal walls were somewhat cleaner after using UNICONE with reciprocal movements (80%) compared to the canals instrumented with XPS ENDO SHAPER (76%), but this difference was not statistically significant.

Conclusion Single-file NiTi systems did not remove smear layer completely, but provided efficient cleaning in the apical part of the canal. UNICONE file with reciprocal movements was somewhat more efficient in removing smear layer compared to the full rotation XPS ENDO SHAPER file.

Published: February 2019

Introduction In everyday clinical practice, we often encounter a lack of space for placing all the teeth present into dental arch; therefore it is often recommended to extract teeth within orthodontic treatment. In clinical practice, the most commonly used methods of closing space after are elastic chains and NiTi closed spiral springs. The aim of this paper was to compare postextraction space closure speed using two different sliding mechanisms, NiTi closed coil springs and elastic chains within treatment with fixed orthodontic appliances.

Material and Method The total sample in this study consisted of 46 postexstraction spaces in 23 patients indicated for the extraction of first premolars using treatment with fixed orthodontic appliances. Two sliding mechanisms, NiTi closed coil spring and elastic chains were applied to postextraction space closure. Postextraction spaces were monitored for 4 months with appointments every 4 weeks. During appointments mechanisms were activated and digital caliper was used to measure the width of the postextraction space.

Results The results showed that NiTi closed coil springs method achieved greater reduction in postexstraction space (3.94 mm) while with elastic chain method the closure of 3.10 mm was achieved. The total difference between these two methods in the observed period was 0.84mm and no statistically significant difference was found (p> 0.05). The lowest value for NiTi closed springs was 2.19 mm, while for the elastic chain it was 1.29 mm. The best postextraction space closure was 5.70 mm and it was completed using NiTi closed springs while for elastic chain the best value was 4.80 mm.

Conclusion: NiTi closed coil springs lead to faster closure of postextraction spaces in relation to elastic chain. Since this difference is minimal, in practice, both methods can be used equally.

Authors: Zebić Maja Ležaja , Jakovljević Nikola , Miletić Vesna
Published: February 2019

Introduction The aim of the study was to quantify and compare fluoride release from four different glass ionomer cement products (GICs).

Materials and Methods Standardized disk-shaped samples (5x2mm; n=5/group) of GIC restorative materials: conventional (Fuji IX, GC Corp., Japan), resin-modified (Fuji II LC, GC) and hybrid glass ionomer cement (Equia Forte, GC) and a conventional GIC liner/base material (Alfagal, Galenika, Serbia) were tested for fluoride release up to 21 days postsetting. Each sample was immersed in 5 mL of fresh deionized water during each time interval. Universal microhybrid composite (Filtek Z250, 3M EPSE, USA) and adhesive (Adper Single Bond, 3M ESPE) were used as negative controls. Fluoride release was measured using an F-selective electrode (Cole-Parmer, USA) and an ion meter (Oakton 700, Cole-Parmer, USA). Data were statistically analyzed using one-way ANOVA, regression and correlation analysis at 0.05.

Results The highest total fluoride release was measured from Alfagal (386±61 ppm/g), and significantly less from Equia (188±29 ppm/g), Fuji IX (143±11 ppm/g) and Fuji II LC (104±14 ppm/g) (p < 0.05). All GICs showed the highest fluoride release during the first 24 hours post-setting. After 3 days, fluoride release slowed down reaching a plateau for all materials. Regression and Pearson correlation analysis showed significant inverse relationship between fluoride release and sample mass and density (p<0.001).

Conclusion Of the three GICs indicated for use as restorative materials, Equia Forte released the highest fluoride concentration. Fluoride release was material and density dependent, with higher release occurring from lower density GICs.

Authors: Nešković Jelena , Jovanović-Medojević Milica , Grga Đurica , Popovic Branka , Živković Slavoljub
Published: February 2019

Introduction The main objective of endodontic treatment is to eliminate infection from root canal and prevent reinfection by three-dimensional hermetic obturation of the canal system. Endodontic failure can occur due to inability of complete control and elimination of infection from the root canal.

The aim of this study is to investigate, by PCR technique, microbiological status of previously endodontically unsuccessfully treated teeth immediately after the removal of obturation material.

Material and Methods The analysis included 30 teeth indicated for endodontic retreatment. After removing previous root canal filling material, the bacteriological sample was taken by sterile instrument (# 15) and paper points. Standard PCR technique was used to analyze the incidence of E.faecalis, P.micros, P.intermedia, P. endodontalis and A.actinomycetemcomitans.

Results Positive bacteriological findings were registered in 80% of cases, while bacteria were not identified in 20% of all samples (all taken from the root canals without significant changes in periapical tissue). From 24 canals with identified bacteria, 17 had affected apical periodontium. The most dominant microbe in root canals with positive bacteriological finding was E.faecalis (83.3% of the canals) and P.intermedia (75%). In case of teeth with chronic periapical changes, the most common was E. faecalis (94%) and P.intermedia (82.3%).

Conclusion The presence of periapical lesions significantly affects microbiological status of endodontically treated teeth. The presence of bacteria was confirmed in most teeth with periapical lesions, while the most frequently identified bacteria were E. faecalis, P.intermedia and P.micros.

Published: February 2019

Important factor related to the conception possibility is women age. The decline in fertility with aging is proven and evident in literature. Infertility is increasing and many couples seek help in advanced techniques such as IVF (in vitro fertilization) in order to overcome the problem caused by aging, but the quality of the oocytes is a significant limiting factor. With the aging the quantity and quality of oocytes decreases, such as the quality of the embryo after fertilization. The accelerated rhythm of life, liberty and women inclusion in all kinds of professions brought many benefits to women, but also increasingly postponing births. Each person is unique individual, and can be more or less fertile compared to the average at same age. Unfortunately, some women has a rapid decline in fertility - accelerate aging, very early, already in the early twenties and when testing them with different methods and exams, the result is very low number of oocytes, low value of anti-Müllerian hormone and also very poor quality of these oocytes, or low ovarian reserve. The problem is that when you have accelerate aging, even IVF techniques can not be of great help in achieving pregnancy. The pregnancy rate (17,65%) and the childbirth rate (5,88%) with the patients older than 40 is very low, although comparable to the data from the scientific literature and speaks in favour of the fact that the success of assisted reproductive techniques is very modest with women older than 44.

Published: February 2019

The treatment of chronic wounds is a continuously developing research focus. The problems of excessive mechanical forces, infection, inflammation, reduced production of growth factors, and lack of collagen will affect the results of treatment. The purpose of this study was to analysse the elements that lead to long-term non-healing of chronic wounds and trophic ulcers, including diabetic foot syndrome, by determining the optimal treatment algorithm. The paper presents an analysis of the world literature on the etiopathogenesis and principles of chronic wound treatment in diabetic foot syndrome. The epidemiology of chronic wounds of different genesis is presented. The issues of physiological and metabolic disorders in chronic ulcers affecting the process of wound healing are discussed. Particular attention is paid to collagen, which is a protein that forms the basis of connective tissue; collagen ensures the strength and elasticity of the skin, which confirms the importance of its role not only in aesthetics but also in the process of wound healing. Different types of collagen and their roles in the mechanisms of chronic wound healing in diabetic foot syndrome are described. The results of clinical studies evaluating the effectiveness of medical products and preparations, consisting of collagen with preserved (native collagen) and fractionated structures, in treating chronic wounds of diabetic foot syndrome are analysed. It has been shown that the use of native collagen preparations is a promising treatment for chronic ulcers and wounds, including diabetic foot syndrome, which makes it possible to increase the effectiveness of treatment and reduce the economic costs of managing these patients.

This study was divided into experimental part of study which was conducted on 75 Wistar rats with the modeled periodontitis and and clinical part of research which included 106 patients with the chronic generalized periodontitis (CGP). The study established an importance of the oxidative stress (both local and systemic) in development and progress of the disease. It is found out that the saliva of rats with the modeled periodontitis there is the reliable increase in the content of total protein, alkaline phosphatase (ALP) and malonic dialdehyde (MDA) in 1.2, 2.6 and 2.8 times respectively, with the reduced activity of catalase in 2.5 times (all p<0.05). It is determined that the gingiva tissue of rats with the modeled periodontitis has the reduced contents of total protein, collagen, elastin and sulfated glycosaminoglycans in 2.8, 1.5, 1.6 and 1.3 times respectively (all p<0.05). It is proved that the antioxidant (AO) therapy normalizes in the rat saliva the content of protein and MDA (decrease in 1,2 and 1,8 times accordingly, p<0.05) and increases the activity of catalase (in 2.5 times, p<0,05). Calcium D3 normalizes the protein content and activity of ALP (decrease in 1.2 and 1.5 times, respectively, p<0.05).

It is found out that the saliva of patients with CGP in the acute phase the content of protein, ALP and MDA increases in 1.9, 2.2 and 1.5 times accordingly (p<0,05) with the reduced catalase activity in 1,1 times (p<0,05). It is revealed that the inclusion of CGP patents in AO complex therapy results jointly with the best clinical effect in the more expressed reduction in generation of reactive oxygen species and lipid peroxidation and also the increased plasma APA.

Five hundred grams of N. oleander was taken from the plant parts and the extracts were mixed with distilled water (1.5 L). The extracts were applied to Pistacia species for 24 and 48 hours. The results showed that the extract had positive effects on their germination and growths of the species mentioned above. The highest germination rate for all the Pistacia species was obtained from the extracts of flower, while the lowest germination rate was recorded in the mixture of all parts of N. oleander mentioned above. Moreover, the treatment time was found to reduce the germination ratio. It was also found that the extracts from the stem of N. oleander were the most effective on the stem height of the Pistacia species studied. It was followed by the extracts from branches, leaves and flower, respectively. Furthermore, the findings indicated that the extracts from the stem of N. oleander had pronounced effect on the stem diameter of the Pistacia species studied. It was followed by the extracts from flower, leaves, and branches, respectively. In general, the effects of the extracts from several parts of N. oleander on the germination and other growing parameters were found to be almost comparable to those of synthetic promoter, Gibberellic Acid (GA3).

Bu çalışmada, köpük kurutma yöntemi kullanılarak incirin sıcak hava (60, 70, 80Â°C) ve mikrodalga (100, 300, 600 W) ile kurutma işlemi gerçekleştirilmiş, kurutma işlem parametrelerinin ve köpük kalınlığının kurutma kinetiğine etkisi incelenmiştir. Kurutma işlemi yalnızca düşen kurutma periyodunda gerçeklemiş ve sabit kurutma periyodu gözlenmemiştir. Mikrodalga ile kurutma, köpük yüzeylerindeki büyük buharlaşma alanına ek olarak hacimsel ısıtma sağlaması nedeniyle sıcak hava ile kurutmaya kıyasla daha kısa sürede tamamlanmıştır. Sıcaklığın ve mikrodalga gücünün artması kuruma sürelerini kısaltırken, köpük kalınlığının artması ile kuruma süreleri uzamıştır. Kinetik parametreleri belirlemek için, deneysel kurutma verileri Fick‘in 2. difüzyon denkleminin yarı deneysel modellerine yerleştirilmiştir. Bunlar arasında, Wang ve Singh modeli mikrodalga kurutma için daha iyi bir uyum sağlarken, Logaritmik model sıcak hava ile kurutma için daha uygun bulunmuştur. Mikrodalga ve sıcak hava kurutma için etkili difüzyon katsayısı değerleri sırasıyla 9,94×10-10-405,69×10-10 ve 13,26×10-10-26,65×10-10 m2Â·s-1 aralığında değişim göstermiştir. Kurutma sıcaklığı, mikrodalga gücü ve köpük kalınlığının artmasıyla etkili difüzyon katsayısı değerleri artmıştır. Kalınlığın artması yapıdaki boşlukların artmasını ve ısı iletiminin konveksiyonla gerçekleşmesini sağlayarak etkili difüzyon yayılımının desteklenmesini sağlamıştır. Aktivasyon enerjisi Arrhenius denklemi kullanılarak mikrodalga kurutma için 2,195-2,379 WÂ·g-1 aralığında, sıcak hava ile kurutma için ise 12,952-21,426 kJÂ·mol-1 aralığında bulunmuştur.

Seed viability and vigor have been influenced by several factors including soil and climatic conditions, plant nutrition, fertilization, irrigation, plant population and post-harvest storages. The study was conducted to determine the appropriate plant density for vigorous seed production in safflower. The effects of row spacing (14 and 28 cm) and seeding rate (40, 80, 120, 160 and 200 seeds m-2) on yield, yield components and seed quality of safflower were detected in the study. The results showed that increased seeding rates resulted in enhanced seed yield and the highest seed yield was obtained from 14 cm and 200 seed m-2 with 3320 kg ha-1. The row spacing and seeding rate did not cause a significant difference in oil and protein contents. Laboratory emergence, germination after accelerated ageing (AA) and electrical conductivity tests were suitable for determining seed quality among the seed lots, while standard germination, cool and cold tests were not appropriate. The highest laboratory emergence percentage and germination after AA were determined in 80 seed m-2 but field emergence percentage in 120 seed m-2. It was concluded that the 14 cm row spacing and seeding rate of 120 seed m-2 should be advised for high yielding seed production regardless of seed vigor in safflower.

This study was carried out to determine the concentrations of some heavy metals (Cd, Cu, Pb, Zn, Cr and Fe) in Solen marginatus (Pulteney, 1799) and sediments in the middle region of Izmir Bay. Metal concentrations in S. marginatus vary in the one-year period between summer 2005 and summer 2006. The order of accumulation of metal concentrates in soft tissue of razor clam was determined as Cd < Pb < Cr< Cu < Zn < Fe. Metal accumulations in the soft tissue of S. marginatus were compared with Provisional Tolerable Weakly Intakes (PTWI) and Provisional Tolerable Daily Intakes (PTDI) for human consumption. The results show that the maximum concentrations of metals were markedly below the limits of the FAO (Food and Agriculture Organization), WHO (World Health Organization) and TFC (Turkish Food Codex) for human consumption. The order of the metal concentrations detected in the sediment samples was Cd < Pb < Cu< Cr < Zn < Fe. In this study, the maximum heavy metal values determined in the sediment are below the criteria values of the stated for international sediment quality guidelines in the NOAA (The National Oceanic and Atmospheric Administration), OMEE (The Ministry of Environment and Energy of Ontario), ANZECC (The Australia and New Zealand Environmental on Conservation Council), CCME (The Canadian Council of Ministers of Environment). There was a statistically significant but weak correlation between concentrations of Cu and Cr in sediment and S. marginatus. The significant correlations have shown that Solen species can be used as a bioindicator species, such as mussels due to their ability to accumulate heavy metals.
