Today, transplantation of cryopreserved fragments of immature testis is a non-alternative method of preserving the fertility of pre-adolescent patients who undergo cytotoxic therapy.The purpose of the study is to compare the effectiveness of the use of biopolymers (bovine serum albumin and fibrin gel) as the bases of cryoprotective media at low temperature preservation of the fragments of the convoluted seminiferous tubules of prepubertal rats’ testis.Materials and methods. Convoluted seminiferous tubules of prepubertal rats’ testis (75 ± 3 mg and 6-8 mm3), after a 30-minute exposure at 4 °C in cryoprotective media based on Hanks’ solution with 50 g/L of bovine serum albumin (BSA) or fibrin gel (FG) supplemented with 0.6 M DMSO or 0.7 M glycerol, were cryopreserved according to the program: 1 °C/min to -8 °C; stop for 10 minutes; 10 °C/min to -70 °C; stored in liquid nitrogen. After thawing, the histological structure was evaluated and the metabolic activity of the spermatogenic epithelium cells was determined.Results. According to the results of the histological study, there was a positive tendency of FG application, which had the maximum expressiveness in combination with 0,7 M glycerol. In this case, 68.8 ± 15.7 % of cell nuclei remained morphologically intact, and changes in the spermatogenic epithelium were slightly pronounced. The metabolic activity of the rats’ seminiferous convoluted tubules cells after freezing and thawing remained at a significantly higher level when using FG in combination with 0.6 M DMSO than with 0.7 M glycerol compared to the corresponding cryoprotectant based on the Hanks’ solution with BSA.Conclusions. The use of fibrin gel in the protocols of cryopreservation provide to preserve the histological structure and metabolic activity of the spermatogenic epithelium.

The dark side of the breastfeeding: In the light of endocrine disruptors
Authors: Chemek Marouane , Nevoral Jan 
Published: July 2019

Abstract
Breastfeeding plays an essential role in the healthy development of a newborn, but human milk is obviously compromised by pollutants from our environment. The main contaminants of human milk with endocrine-disrupting compound (EDCs) have raised concern for public and environmental health. Bisphenol A (BPA), which can leach from plastics, are among the most well-studied. Since EDs are known to cross the mammary gland barrier and BPA may accumulate in the neonate, “BPA-free” products have been introduced to the market. However, recent studies have shown that alternative bisphenols (e.g. BPS, BPF) can be detected in breast milk, have ED activities and may have developmental effects similar to BPA.
Nationalism and Anti-Semitism in an Independent Romania
Authors: Motta Giuseppe 
Published: July 2019

Abstract
The history of antisemitism in Romania is strictly connected to the religious and cultural framework of those territories, as well as to their political integration from the age of emancipation and independence to the establishment of a Greater Romania after World War I. This article aims to analyse the different intersections of this historical process and the continuity between the old forms of anti-judaism and their re-interpretation according to modernist dynamics during the first half of the Twentieth-Century. The Romanian case illustrates the transformation and re-adapting of old religious prejudice in new doctrines of xenophobia, nationalism and antisemitism.
The Assessment of Expert Evidence on DNA in Malaysia

Published: July 2019

Abstract
One of the most common forms of evidence used by the Public Prosecutor in a courtroom to prove a case is DNA evidence. The DNA evidence process started when the police collected the physical evidence relevant to the alleged offence at the crime scene. The collected evidence will then usually be sent to the Department of Chemistry Malaysia for DNA analysis. The chemist will extract the DNA from the relevant physical evidence by using specific techniques. The outcome of the analysis will be used to complete the investigation of the case. Being an independent organization, the Chemistry Department strives to provide impartial forensic science analysis. Thus, from the analysis, sometimes DNA evidence does not necessarily implicate the accused with the alleged offence but may also disclose the involvement of a third party in the alleged offence that may cast doubt on the prosecution’s case. This can be seen in the Federal Court’s case of Public Prosecutor v Hanif Basree Abdul Rahman [2008] 4 CLJ 1. The evidence will then be presented by the prosecution before the court to assist judges in making the right decisions. This indicates the important role played by an expert in the court decision making process. In this context, questions always arise as to the probative value of DNA evidence given by experts in the courtroom. Can the court convict a person solely on DNA evidence? This article focuses on the position of DNA experts in Malaysia under section 45 of the Evidence Act 1950. It was found that although the DNA evidence is given by the experts, the probative value depends on the nature of the evidence itself.

Published: July 2019

Abstract
Regional politics play a decisive role in national politics when region poses ethnic groups in competing manner. Sri Lanka’s Eastern province has been a contested region in terms of ethnic and territorial integration as well as the integration of majority and minorities from the independence of the country, during civil war, and in the post-civil war era. This study explores the ethnic groups’ competition for political control and autonomy, as well as its impact in Eastern Sri Lanka. This study has employed both qualitative and quantitative data, collected mainly through secondary sources such as literary books, book chapters, journal articles, newspaper cuttings, and government documents, which are analyzed and presented through interpretive and descriptive manners. The study has found that the Eastern province has been a contested choice for the ethnic majority to extend their ethnic domination, and to implement ethno-centric development-cum settlement policies and programs, all of which are ultimately induced to change the ethnic composition of the region and pushed ethnic minorities to mobilize and demand for more decentralized power and autonomy in the region. The thirty-year prolonged civil war made the region not only a war-torn, but also let to undermining regional democratic principles, including minorities’ rights for autonomy. The study also reveals that the new emerging post-war political context at the provincial and national levels continues to undermine the minorities’ hopes for autonomy in the region. Nevertheless, the region has emerged as ‘role-model’ for ethnic cohesive politics.

The Relationship between Ownership Structure and Dividend Policy: An Application in Vietnam Stock Exchange
Authors: Tran Thi Xuan Anh , Le Quoc Tuan 
Published: July 2019

Abstract
This research examines the possible association between ownership structure and Vietnam listed companies’ dividend payout policy over the period of 2009 – 2015. We have investigated 642 listed firms in Hochiminh stock exchange and Hanoi stock exchange, using pannel data analysis. Ownership structure is described with two main sub-variables: ownership concentration and ownership composition. Specifically, the Herfindahl index (or H-index) was applied to measure the level of ownership concentration /dispersion for all major shareholders in the company, including the five biggest investors, corporate institutional investors, the ownership concentration level, and foreign investors. It has been observed that the H-index of all major shareholders has an average of less than 0.5 but the value of the H-index of institutional investors at 0.594 indicates that institutional investors are more likely to be concentrated in the hands of large institutional investors. The result showed linear relationship between institutional ownership and the dividend rate, but not statistically significant for the relationship between managerial ownership and dividend payout ratio.

Abstract
Relevance of the problem under study is explained by the beginning of a new stage in the development of Russian volunteer movement in the field of preservation of cultural monuments, which coincided with the rise of research interest in volunteering in general. The objective of this paper consists in comprehensive analysis of the modern history of restoration voluntary movement in Russia, examination of evolvement of public voluntary practices in the field of protection of the architectural heritage of the country in the context of general cultural, socio-economic, political processes that have taken place in Russia over the past decades, which have determined the specific organizational forms, content and activities of voluntary activists. The leading approach to the study of this problem is the historical method, as well as methodological principles of historicism, scientificity, objectivity, as well as sociality, integrity and fundamentality, involving the study of the historical process of volunteering in the totality of facts and sources in their logical and chronological sequence. The paper describes the main forms of volunteer practices for monument preservation, gives an overview of volunteer initiatives, as well as the efforts of charitable foundations and public organizations aimed at rescuing the cultural heritage of the country, identifies the development trajectories of restoration volunteering, and also specifies the key trends, based on which the tendency to professionalization and gradual expansion of the scope of voluntary work has been revealed. Materials of the paper can be useful not only for scientists, engaged in research of problems of social history of our country, but also for specialists from social sphere, organizers of work with youth, and also students of socio-humanitarian and pedagogical profiles.

Abstract
Although, studies have shown several cases of kidnapping in both developed and developing countries but the case of a developing country like Nigeria is seems to be pathetic and worrisome, largely because of its contributions to the ancient slave trade that greatly affected several Nigerians for many centuries in the past. With such awful experiences in the past and its contribution to backwardness of the human race, one would have thought that cases of kidnapping would never occur in Nigeria, but the reverse has been the case in the contemporary. Hence, several studies have emerged on the subject of kidnapping in recent times. However, it could be observed that these studies are strongly connected with rituals power, wealth and traditional purposes. While the nature of the Nigerian society which is characterised by injustice and its contributions to the menace of kidnapping has been hitherto neglected in academic literature. The present study intends to address this flaw in knowledge by addressing the three research questions raised. Being a review paper, the study engaged secondary data in collecting relevant information to analyse and illustrate questions raised. The study argues that if the current high level of injustice in Nigeria could be reduced, there may be a corresponding reduction in the cases of kidnapping.
Virtual Realism: Really Realism or only Virtually so? A Comment on D. J. Chalmers’s Petrus Hispanus Lectures
Authors: Beisbart Claus 
Published: July 2019

Abstract
What is the status of a cat in a virtual reality environment? Is it a real object? Or part of a fiction? Virtual realism, as defended by D. J. Chalmers, takes it to be a virtual object that really exists, that has properties and is involved in real events. His preferred specification of virtual realism identifies the cat with a digital object. The project of this paper is to use a comparison between virtual reality environments and scientific computer simulations to critically engage with Chalmers’s position. I first argue that, if it is sound, his virtual realism should also be applied to objects that figure in scientific computer simulations, e.g. to simulated galaxies. This leads to a slippery slope because it implies an unreasonable proliferation of digital objects. A philosophical analysis of scientific computer simulations suggests an alternative picture: The cat and the galaxies are parts of fictional models for which the computer provides model descriptions. This result motivates a deeper analysis of the way in which Chalmers builds up his realism. I argue that he buys realism too cheap. For instance, he does not really specify what virtual objects are supposed to be. As a result, rhetoric aside, his virtual realism isn’t far from a sort of fictionalism.
Virtual Reality: Fictional all the Way Down (and that’s OK)
Authors: Juul Jesper 
Published: July 2019

Abstract
Are virtual objects real? I will claim that the question sets us up for the wrong type of conclusion: Chalmers (2017) argues that a virtual calculator (like other entities) is a real calculator when it is “organizationally invariant” with its non-virtual counterpart—when it performs calculation. However, virtual reality and games are defined by the fact that they always selectively implement their source material. Even the most detailed virtual car will still have an infinite range of details which are missing (gas, engines, pistons, fuel, chemical reactions, molecules, atoms). This means that even the most detailed virtual object will still have fictional aspects. Rather than argue that virtual objects are, or aren’t, real, it is preferable to think of overlaps and continuities between the fictional and the real, where even the most painstakingly detailed virtual reality implementation of a non-virtual object is still art: a human process of selection and interpretation. Virtual reality should therefore not be philosophically understood just as a technological implementation on a trajectory to perfection, but as a cultural artifact which derives its value in part from its simplification and difference from its source material.
Investigation of Fatigue Damage in General, Prestress, and Concrete Beam Reinforced with FRP Sheets and Concrete Beam Influenced By Mix Beam Under Periodic Load in Linear and Nonlinear Phase
Authors: Jedkareh O. , Gholi Zad A. 
Published: July 2019

Abstract
Reinforcement of concrete components using FRP is one of the new strengthening methods that replaces old methods such as steel or concrete reinforcement. In spite of the extensive research on numerical analysis (limited components) of the behavior of components of reinforced concrete, few studies have been done on components of prestress concrete and its components limited modelling. In this study, using the Abaqus software, the behavior of four samples of concrete beams under periodic load, including original, prestress, reinforced with FRP sheets and influenced by both prestress and reinforced with FRP sheets (mix beam) was modelled. Prestress in structural fatigue showed that in both loading and unloading conditions, the prestress beam is more strength than the original beam.
Pro-ecological Views of Kosovar Teachers Measured by Endorsement of the New Ecological Paradigm Statements

Published: July 2019

Abstract
The New Ecological Paradigm (NEP) scale is a survey-based metric devised to measure the environmental concerns of groups of people through using a standard survey instrument. This is the first research to measure how in-service teachers perceive the NEP scale in Kosovo. The aim of the current study was to assess the concerns of teachers in Kosovo about environment in the age of Anthropocene by supporting anthropocentric or eco-centric views through using NEP scale as a standardized instrument. Thus, the research was an attempt to investigate how teachers perceived changes in the environment and how much they agreed with the 15 NEP statements. This study followed a quantitative methodology, employing a questionnaire to secure socio-economic data about the teachers, the information sources that they used for environmental information, their perceptions about changes in the environment in the past decade, expectations for the next decade, and the support of the NEP’s statements. A total number of 88 primary school teachers (teaching grades 1–5) participated in this study who came from three most populated regions of Kosovo. The teachers responded to the questionnaire based on their teaching experience, sources of environmental information which they used, their perceptions and expectations in the environmental changes, and their attitudes toward the NEP statements. The results of the research showed that teachers’ concerns about environmental developments were mostly consistent with the views of the NEP scale or pro-ecological worldviews. The survey results provided a positive indication that Kosovar teachers sought to offer a new eco-centric worldview for the next generation, instead of the anthropocentric one in which they had been living.
Raising Saudi Students’ (Energy) Sustainability Awareness through ESL – Teachers’ Thoughts
Authors: Hamdan Alghamdi Amani K. , El-Hassan Wai Si 
Published: July 2019

Abstract
This inaugural qualitative study solicited English as Second Language (ESL) teachers’ thoughts about using ESL to teach Saudi Arabian (SA) university foundation year students about and raise their awareness of energy and sustainability issues. Fourteen participants from three higher education institutions in the Eastern Province of SA prepared typed responses in a word office document to 15 questions pertaining to ESL teachers’ perceptions, opinions, beliefs, attitudes, knowledge, and values of using ESL to teach sustainability. Data returned by email were iteratively read and insights culled to provide an inaugural profile of ESL teachers’ thoughts about this pedagogical innovation in SA higher education preparatory-year programs. The findings indicated a positive picture towards incorporating sustainability topics into Saudi Arabian ESL curriculum. Participants were enthusiastic about such tasks and about seeking knowledge related to sustainability by various means to augment lack of knowledge. They were of the opinion that this is a legitimate role for ESL teachers and believed that they would be effective and bring value to students’ learning. They readily suggested rich ideas about what a sustainability-infused ESL curriculum would look like. This study was an original one in that it solicited and shared the voices of ESL teachers in SA about the idea of concurrently teaching language and sustainability. Nominal research addresses this pedagogical approach meaning the findings are valuable to ESL training schools, SA university foundation program planners, SA higher education curriculum developers and higher education human resource managers who recruit and hire ESL instructors.
“Open” Category Unmanned Aerial Systems Harmonized Standards and Requirements Complex
Authors: Andonov Andon 
Published: July 2019

Abstract
The steadily increasing use of unmanned aerial systems (UAS) is an important factor for the military and civil aviation safety on a global scale. One of the critical conditions for the efficient functioning of the European aviation safety system is the establishment and implementation in practice of a comprehensive regulatory framework for the use of unmanned systems in the Common European Airspace. The aviation authorities and industry strive to introduce a set of rules and requirements that adequately and flexibly guarantee a high level of safety without limiting the development of the UAS market. This article proposes a set of standards that should be met by “Open” category UAS with the intention to execute operations in the European airspace.
