Published: May 2014

Abstract
The purpose of this study was to establish the anthropometric and physical profiles of elite young soccer players according to their playing position, and to determine their relevance for the selection process. One hundred and fifty-six young male soccer players participated in the study. Players were classified into the following groups: Goalkeepers (n=16), Central Defenders (n=26), External Defenders (n=29), Central Midfielders (n=34), External Midfielders (n=28), and Forwards (n=23). Anthropometric variables of participants (body height, body mass, body mass index, 6 skinfolds, 4 diameters, and 3 perimeters) were measured. Participants performed the Yo-Yo test, sprint tests (30 m flat sprint and Balsom agility test) and 2 jump tests (countermovement jump and the Abalakov test). At the end of the season, the technical staff of the club selected some of the players to continue playing on the same team and the rest were not selected. The results show that heavier and taller outfield players performed better in vertical jumps and sprint tests, whereas leaner outfield players performed better in the Yo-Yo test. Fat percentage of selected players was lower than that of the non-selected ones. The rest of the body components were similar in the selected and non-selected players within each playing position. Moreover, the selected players performed slightly better than the non-selected players in the physical test, but these differences were not statistically significant.
Relationship Between Break-Time Physical Activity, Age, and Sex in a Rural Primary Schools, Wales, UK
Authors: Escalante Yolanda , Backx Karianne , Saavedra M. 
Published: May 2014

Abstract
The aim of this study was to examine the physical activity during the break-times of primary school children in rural areas, and its relationship with age and sex. 380 children (192 boys and 188 girls; age=9.5±1.1 years) participated in the study. Break-time physical activity in the morning and lunch breaks was measured by accelerometry. An ANOVA was used to determine differences by sex in each age group, together with the respective confidence intervals and effect sizes. The results showed that 8-year-olds performed more physical exercise than 11-year-olds during the two breaks (p=0.005). For the boys, the 8-year-olds did more physical activity than the 10-year-olds, while, for the girls, those aged 8 and 9 years did more PA than girls aged 11 years (p<0.001). The only difference between boys and girls was for the 10-year-olds (p=0.043), with the boys doing more physical activity. Teachers might find it useful to take these findings into account to design physical activity programmes aimed at increasing the playground physical activity of older children.
The Art of Stopping when it’s Time to Stop. A Philosophical Approach to the Daoist Notion of Wú wéi
Authors: Budriūnaitė Agnė 
Published: May 2014

Abstract
One of the most significant current discussions in Chinese philosophy is the problem of interpreting the notion of wú wéi. As one of the popular concepts of ancient Chinese thought, wú wéi was used and differently interpreted in various philosophical schools from the very beginning. In this article, the Daoist notion of wú wéi will be explored as the “art of stopping when it’s time to stop”, taking the philosophical approach and appealing to the text of the Zhuangzi. The critical investigation into the sinological literature allows us to reveal several different contemporary attitudes towards wú wéi as the aim, process, and ground for the “ideal” human existence
Latin America through the Literary Looking-Glass, And What Bolaño Found There
Authors: Stramskas Arnoldas 
Published: May 2014

AbstractThis article provides a broad overview of social, economic, and cultural politics in Latin America, especially concentrating on what became known as the Latin American literary “boom” in the 1960s and 1970s, and the region’s political context - colonial past, neocolonial/neoliberal present, the role of intellectuals within the state and cultural affairs. The second part focuses on Roberto Bolaño - the writer who put Latin American literature on the world map which has not been seen since the boom years - and his novel The Savage Detectives. The aim of this article is to demonstrate that literature not only shares common elements and possible intentions with social and political critique, but that it can also be an effective form of social and political criticism. In such a case, Bolaño’s work may be read not as inferior fictional account but as a complex, intersectional investigation of socioeconomic as well as ontological condition in Latin America that other modes of inquiry may overlook.
The zebrafish as a model to study the inflammasome
Authors: Angosto Diego , Mulero Victoriano 
Published: May 2014

AbstractOur knowledge about the inflammasome and the nucleotide-binding domain and leucine-rich repeat containing receptor (NLR) family has increased enormously during recent years due to studies in transgenic and mutant mouse models. Although the mouse provides many advantages for deciphering the mechanisms involved in inflammasome activation and its role in immunity, other animal models, such as the zebrafish may be complementary, especially for the in vivo visualization of inflammasome activation. Indeed, the zebrafish has emerged as an excellent model to study a wide variety of diseases due to its unique advantages, including its transparency and easy genetic manipulation. Here we briefly discuss the evolutionary aspects of the inflammasome and consider the use of the zebrafish to study the inflammasome complementary to the widely used mouse model.

Abstract
In this communication, selected physicomechanical characteristics of ground turmeric (cv. Prabha) were investigated for cryogenic and ambient grinding conditions of turmeric at different moisture contents (4, 6, 8 and 10% w.b.). A cryogenic grinder (Model: 100 UPZ, Hosokawa Alpine, Germany) and a micro pulverizer (hammer mill) were used for cryogenic and ambient grinding, respectively. The ground turmeric was graded in three grades viz. Gr-I, Gr-II and Gr-III with a sieve shaker using BSS Nos. 40, 85 and pan, respectively. Tap densities for cryogenic and ambient ground turmeric decreased from 678.7 (Gr-I) to 546.7 kgm-3 (Gr-III) and from 642.3 (Gr-I) to 468.6 kgm-3 (Gr-III), respectively, with the moisture increase. The angle of repose for cryogenic and ambient ground turmeric increased linearly from 26.85 (Gr-I) to 34.0° (Gr-III) and from 23.10 (Gr-I) to 28.06° (Gr-III), respectively with the increase in moisture content. The static coefficient of friction was the highest on plywood surface followed by mild steel sheet and galvanized iron sheet. The cryoground samples were found better in colour. Thermal conductivity of cryo-ground samples was higher than that of ambient ground samples. These physico-mechanical characteristics of cryogenic and ambient ground turmeric will be helpful for packaging, handling, and storage.

Abstract
Understanding soil spatial variability and identifying soil parameters most determinant to soil organic carbon stock is pivotal to precision in ecological modelling, prediction, estimation and management of soil within a landscape. This study investigates and describes field soil variability and its structural pattern for agricultural management decisions. The main aim was to relate variation in soil organic carbon stock to soil properties and to estimate soil organic carbon stock from the soil properties. A transect sampling of 100 points at 3 m intervals was carried out. Soils were sampled and analyzed for soil organic carbon and other selected soil properties along with determination of dry aggregate and water-stable aggregate fractions. Principal component analysis, geostatistics, and state-space analysis were conducted on the analyzed soil properties. The first three principal components explained 53.2% of the total variation; Principal Component 1 was dominated by soil exchange complex and dry sieved macroaggregates clusters. Exponential semivariogram model described the structure of soil organic carbon stock with a strong dependence indicating that soil organic carbon values were correlated up to 10.8m.Neighbouring values of soil organic carbon stock, all waterstable aggregate fractions, and dithionite and pyrophosphate iron gave reliable estimate of soil organic carbon stock by state-space.

Published: May 2014

Abstract
In a power transformer as one of the major component in electric power networks, partial discharge (PD) is a major source of insulation failure. Therefore the accurate and high speed techniques for locating of PD sources are required regarding to repair and maintenance. In this paper an attempt has been made to introduce the novel methods based on two different artificial neural networks (ANN) for identifying PD location in the power transformers. In present report Fuzzy ARTmap and Bayesian neural networks are employed for PD locating while using detailed model (DM) for a power transformer for simulation purposes. In present paper PD phenomenon is implemented in different points of transformer winding using threecapacitor model. Then impulse test is applied to transformer terminals in order to use produced current in neutral point for training and test of employed ANNs. In practice obtained current signals include noise components. Thus the performance of Fuzzy ARTmap and Bayesian networks for correct identification of PD location in a noisy condition for detected currents is also investigated. In this paper RBF learning procedure is used for Bayesian network, while Markov chain Monte Carlo (MCMC) method is employed for training of Fuzzy ARTmap network for locating PD in a power transformer winding and results are compared.

Abstract
This paper introduces the advanced control of single-phase voltage-source active rectifier. This control provide direct control of trolley-wire current and active damping of low-frequency disturbances at the converter ac side. Our proposed control strategy combines PR controller with feed-forward model and low-frequency harmonic compensator based on resonant controllers. Achieved experimental results show excellent converter behavior, where converter is fed by strongly distorted supply voltage.
Autochthonous Versus Allochthonous Organic Matter in Recent Soil C Accumulation Along a Floodplain Biogeomorphic Gradient: An Exploratory Study
Authors: González Eduardo , Cabezas Álvaro , Corenblit Dov , Steiger Johannes 
Published: May 2014

Abstract
The mechanisms controlling soil succession in floodplains remain much less studied than in uplands due to the complexity that flooddriven erosion and sedimentation bring into soil development processes. The amount of organic matter and C generally grows with soil ageing and is controlled by multiple and interacting allogenic and autogenic factors, but to what extent the production of organic matter by in situ vegetation contributes to soil formation in floodplains remains unknown. The objective of this work was to explore the importance of autochthonous organic matter versus allochthonous organic matter in organic C accumulation of floodplain forest soils along a vegetation succession and hydrogeomorphic connectivity gradient. Physicochemical analyses of sediment collected after one single flood event in a large Mediterranean floodplain (Middle Ebro, a 9th order regulated river reach in NE Spain) were used to estimate the proportion of organic C found in the topsoil (first 10 cm) samples of young (<25 yr), mature (25-50 yr) and old (>50 yr) floodplain forests that had an allochthonous (i.e., % of organic C deposited by floods) or autochthonous (i.e., % of organic C produced in situ by vegetation) source. Results of this exploratory study showed that the accumulation of autochthonous organic C in the floodplain topsoil only occurred in floodplain forests older than 50 year-old, but even then, it was more than six-fold less abundant than that with an allochthonous origin. Moreover, a linear mixed effect model showed that, although autochthonous organic C accumulation was mainly explained by the forest structure, a small proportion of it was also controlled by an allogenic factor, the groundwater table depth. Then, groundwater table depth variations could be partly controlling autochthonous organic matter production and decomposition in this Mediterranean floodplain. Although flow regulation and embankment has dramatically limited the hydrogeomorphic dynamics of the river, allogenic overbank sedimentation during flood events still controls floodplain soil succession and organic C accumulation in the floodplain.
Crossing the frontiers. Peer coaching and self-managing in the process of the professional development in multicultural environment
Authors: Mazurkiewicz Grzegorz , Fischer John M. 
Published: May 2014

Abstract
Our effort focuses on the development of a process of cross-cultural peer coaching through which we have sought to grow as reflective practitioners and strengthen authentic conversations between two individuals, from Poland and the United States. By building a theoretical framework around peer coaching, intercultural interaction, and auto-ethnography we have worked to make explicit our development as educators working to enrich the process of the organizational learning and to make education more open, democratic and human. As Kottler [1997] claims, it is possible to find stages that a tourist goes through during the process of recognizing and knowing another culture that was used to mirror the sensation of the professional growth. The findings shed light on how peer coaching might be strengthened, as well as the development of an observation protocol to structure such reflective and, ultimately, life changing work.
Phenomenological Study of Employee Perceptions of Managerial Behaviors as Personal Enactments of Organizational Culture
Authors: Michalak Joanna Małgorzata , Ristino Robert J. 
Published: May 2014

Abstract
Using a phenomenological methodology, this research study examines the phenomenon of organizational culture through the perceptions of those who experience it. Rather than studying how organizational culture affects organizational behavior and success, the researchers focus on employee perceptions of culture as a consequence of experiences with managerial behaviors as personal enactments of culture. The notion of personal enactments is drawn from the work of Edgar Schein. Schein [1985] has identified three levels of organizational culture: artifacts, values and beliefs. Among artifacts, Schein identifies the personal enactments of organizational values by senior managers as one of the more important. The researchers derived the data describing these personal enactments from 20 volunteer subjects reporting in self-administered questionnaires their experiences with managerial behaviors. Respondent perceptions are described in their own words, conveying their understandings, feelings, emotions and behaviors. Responses are categorized into units of relevant meaning, organized into clusters of similar meaning and then into themes. From these themes the researchers draw some insights and understanding of how system actors both live and experience culture in an organizational setting.
Associations of Resistin Levels with Resistin Gene Polymorphism and Metabolic Syndrome in Thais / Asocijacija Nivoa Rezistina Sa Polimorfizmom Gena Za Rezistin I Metaboličkim Sindromom Kod Tajlanđana
Authors: Suriyaprom Kanjana , Tungtrongchitr Rungsunn , Namjuntra Pisit 
Published: May 2014

Summary
Background: Metabolic syndrome (MS) is a clinical constellation comprising risk factors associated with developing cardiovascular disease and type 2 diabetes. Resistin has been suggested as a linkage between obesity, inflammation and type 2 diabetes. This study aimed to investigate resistin concentrations and hematological-biochemical parameters in MS subjects and controls, and to determine whether two resistin gene (RETN) polymorphisms (-420C>G & +299G>A) are linked to resistin levels and MS among Thais.
Methods: This case-control study was performed with 322 Thai volunteers: 160 MS subjects and 162 controls. Anthropometric parameters and hematological-biochemical variables were determined. The RETN -420C>G (rs1862513) and +299G>A (rs3745367) polymorphisms were genotyped by PCR-RFLP technique.
Results: The resistin levels of the MS group were significantly higher than those of the control group. Resistin levels were positively correlated with anthropometric parameters and WBC count in the MS group. According to RETN -420C>G polymorphism, MS subjects with the G allele (CG/GG) (3.9 mg/L) had significantly higher resistin con- centrations than in subjects with the CC genotype (2.4 mg/L); with regard to RETN +299G>A polymorphism, carriers with the A allele (GA/AA) (3.8 mg/L) had significantly higher resistin levels than subjects with the GG genotype (2.7 mg/L), after adjusting for potential covariates. How - ever, the RETN -420C>G and +299G>A poly morphisms were not found to be associated with MS, hematologicalbiochemical parameters and anthropometric variables.
Conclusions: These findings suggest resistin levels are linked with MS and the RETN -420C>G and +299G>A polymorphisms have impacted the circulating resistin concentrations. However, these two RETN polymorphisms pro - bably do not influence susceptibility to MS among Thais.
Antenatal Treatment with Glucocorticoids and the Hypotalamic-Pituitary-Adrenal Axis

Published: May 2014

Summary
Fetal development is a critical period in the life cycle which is why the placenta provides a structural and physiological barrier that protects the fetus from the outer fluctuations and inner disturbances. A variety of influences from the environment, however, might induce fetal overexposure to glucocorticoids that target the fetal hypothalamic-pituitary-adrenal (HPA) axis and influence the fetal growth trajecto-r y. Development of the HPA axis starts in the early stages of pregnancy, but the timing of HPA axis maturation and the glucocorticoid receptor (GR) expression in relation to birth is highly species-specific. The functional state of the fetal HPA axis plays a key role in the maturation of many organs necessary for intrauterine development and existence after birth. A functional HPA axis in near-term fetuses provides an adequate response to stress and also affects the timing of parturition. Due to their potent effect on the maturation of fetal tissues, synthetic glucocorticoids are used in human pregnancy at risk of preterm delivery. Dexamethasone and betamethasone, as the ones most commonly used, cross the placental enzymatic barrier (11b-hydroxysteroid dehydrogenase type 2 – 11b-HSD2) and have 25-fold higher affinity to the GR than endogenous glucocorticoids, stimulating many aspects of fetal maturation. Despite the numerous positive effects, exposure to synthetic glucocorticoids during fetal development may result in intrauterine growth retardation and fetal programming of the HPA axis function which is associated with cardiovascular, metabolic and psychiatric disorders manifested later in life. Long-term consequences indicate the need for the implementation of new studies that will provide a better understanding of the link between glucocorti-coid overexposure during fetal development and adverse outcomes in adulthood.

Published: May 2014

Abstract
The occurrence of stem-base diseases in two cultivars of winter wheat were evaluated in a 3-year experiment, using two agrotechnology levels. The two cultivars evaluated were durum wheat of the Komnata cultivar and common wheat of the Ostka Strzelecka cultivar. The highest intensity was noted in the occurrence of two diseases of the complex, i.e. Fusarium foot rot and eyespot. The examined cultivars were characterized by a similar susceptibility to these diseases. There was an observed difference - a slightly higher susceptibility by the Komnata as opposed to the Ostka Strzelecka cultivar - but it was not significant statistically. Significant differentiation in infestation was noted for other experimental factors like cultivation season and the agrotechnology level. Intensification of the occurrence of both stem-base diseases in the experimental seasons did not affect the mean amount and quality of the yield obtained in the experiment.
Blumeria graminis f. sp. hordei virulence frequency and the powdery mildew incidence on spring barley in the Wielkopolska province
Authors: Tratwal Anna , Bocianowski Jan 
Published: May 2014

Abstract
Powdery mildew caused by fungi Blumeria graminis f. sp. hordei is one of the most common barley diseases in Polish meteorological conditions. The powdery mildew fungus is made up of different races and forms that are highly specialized. Barley cultivars might be resistant to a certain race of the mildew fungus, but susceptible to another race. Development of the disease is rapid in temperatures from 12 to 20°C, and in humid weather. The aim of the two-year experiment was to assess B. graminis f. sp. hordei virulence frequency and powdery mildew occurrence on five spring barley cultivars. Virulence frequency of the pathogen depended on place and term of exposition. The occurrence of powdery mildew on spring barley cultivars depended on virulence frequency of the pathogen and weather conditions.

Published: May 2014

Abstract
The study analyses possibilities of PHA (Preliminary Hazard Analysis) usage in ecological risk assessment conducted within technical risk assessment. The analysis was performed based on results obtained in a study performed between 2007 and 2013 in natural and modified lowland Lower Silesian watercourses. The object of the study was communities of hydromacrophytes being good indicators of the water ecosystem quality. The research constituted a base for the determination of ecological risk factors i.e. the probability of hazard occurrence and its effects. It allowed for the acquisition of the risk classification matrix which included three levels - low, medium and high.
