The content of T-2 and HT-2 mycotoxins in feed and their infl uence on the digestibility of nutrients in broilers
Authors: Vertiprahov V. G. , Gogina N. N.
Published: June 2021

The purpose of the research was to study the content of T-2 and HT-2 toxins in feed and their eff ect on the digestibility of feed nutrients in broilers. The paper provides unique information on the contamination of the feed in the Russian Federation with T-2 and HT-2 toxins. The studies have beene performed using the most objective laboratory method of high-performance chromatography in tandem with mass spectrometry on modern equipment. New knowledge has been obtained about changes in the activity of digestive enzymes in the intestine and blood plasma in meat chickens when they consume feed with different levels of T-2 and HT-2 contamination with toxins. The presence of T-2 toxin at a dose of 1073±53,7 mcg/kg (exceeding the MAC by 10 times) and HT-2 toxin in the feed affects the digestive processes and the digestibility of feed nutrients in meat chickens. The infl uence of T-2 and HT-2 toxins on the digestibility of dry matter of feed, protein, and fat by meat chickens has been determined. The presence of mycotoxins in the feed did not affect the average live weight of broilers. Broiler chickens that consumed feed with mycotoxins lagged behind in growth by 3,8 %, and those who received a feed additive with contaminated feed by 2,7 % from the control group. The use of the feed additive Mycofix Plus 5,0 for the inactivation of mycotoxins in an amount of 1 kg/t when the feed was contaminated with 173 mcg/mg of T-2 and HT-2 toxins was rational and contributed to the improvement of the digestibility and use of feed nutrients by broilers and consequently their productivity.

Biomechanical technology of injury prevention in the training of specialists in physical education and sports
Authors: Kozin S.V
Published: June 2021

Purpose: to develop and experimentally test the biomechanical technology of injury prevention of future specialists in physical education and sports in the process of professional training (rock climbing for example). Material and Methods. The participants of this study were 84 male students engaged in amateur climbing aged 18-19 years. All athletes were also students of physical education faculties of Ukrainian universities; 40 athletes were in the experimental group and 44 athletes were in the control group. The biomechanical technology for injury prevention in the training of specialists in physical education and sports has been developed on rock climbing  for example. Developed biomechanical technology for injury prevention contains 3 areas: 1 - theoretical; 2 - analytical; 3 - practical. Injury risk (incidence) was defined as the number of injuries to the total number of athletes in the analyzed group. Relative risk (incidence rate ratio) was determined by the ratio of risk in the control group to the risk in the experimental group. The chance of injury was defined as the ratio of the number of injuries to the number of uninjured athletes in the analyzed group. The relative chance (Odds Ratio) was defined as the chances of injury in the control group to the chances of injury in the experimental group. These indicators were determined separately for low, medium and severe finger injuries. Results. The applied technology of injury prevention significantly influences the reduction of the number of injuries of athletes – future specialists on the physical education and sports (on rock climbing for example). It is established that the application of the developed technology of injury prevention reduces the risk of finger injuries: low complexity – in 2.364 times (95% CI = 0.925-6.041, P> 0,05) times; medium complexity – in 3.333 times (95% CI = 1.001-11.096, P (Fisher) = 0.030); high complexity – in 8.182 times (95% CI = 1.084-61.749, P (Fisher) = 0.011). Conclusions. The application of the developed biomechanical technology of injury prevention in the process of training specialists in physical education and sports significantly reduces the risk of injury to students.

Published: June 2021

The purpose of this article is to present the issue of the Internet in the everyday lives of young people. The article is a review and synthesis of the findings of ten years of research on young people’s use of the Internet. This article also provides an overview of research conducted primarily in foreign research institutions. The query was based on scientific databases available online (EBSCO, Google Scholar). According to several studies, young people mostly use social media to portray themselves to the rest of the world. They use social media to share images and information about their lives. Teenagers, in particular, are constantly engaging with others online for entertainment as well as to broaden their knowledge and obtain education. One of the most critical aspects of functioning in cyberspace is one's public image on social media.
Theology and psychological concepts of religiosity. The possibilities for interdisciplinary cooperation
Authors: Soiński OFM Borys Jacek
Published: June 2021

The article attempts to outline the possibilities of cooperation between theology and the psychology of religion. The author, using historical and comparative methods, analyzes various models of relations between contemporary theology and the psychology of religion. First, he shows the stages of the development of the Catholic Church's reference to specific sciences from the First Vatican Council to the present day, from recognizing the absence of contradiction between faith and science, through the recognition of the autonomy of theology among the positivistic sciences, to the stage of building cooperation in the post-conciliar period. It then suggests ways of presenting religious issues in various different types of psychology of religion (models of conflict, subordination, parallelism, and integration). The paper also undertaken an explanation of differences between methodological and ontological reductionism in psychologists' understanding of the Absolute as an object of religious relation. It cites D. M. Wulff’s two-dimensional summary scheme as an example of the extraordinary complexity of the problem psychology has in understanding religion. The author further analyzes the attempts at one-dimensional integration of theology and the psychology of religion (understood as two opposite poles of one continuum, where pastoral praxis is a search for the golden mean). Recognizing the inadequacy of these attempts, the author advocates a pluralistic translation of religious phenomena, i.e. interpreting the phenomenon under study based on both psychology and theology. Distinguishing between the empirical order and the revealed (the natural distinguished from the supernatural) in the dialogue between psychology and theology, he proposes to adopt the relationship of convergence rather than that of complementarity. The summary of the previous analyses is the two-dimensional model of cooperation between theology and the psychology of religion as outlined by the author.
Dialogue as a tool in nature conservation
Authors: Latawiec Michał , Latawiec Anna
Published: June 2021

Nature is sensitive to human interventions. They often result in social conflicts. The dilemmas that emerge in this context require explanations. The aim of this article is to show the usefulness of dialogue in the process of making people aware of the essence of these dilemmas. For this reason, we first review the notion of dialogue and the features that characterise this process. The proposed definition of dialogue takes account of its specific role in the understanding of nature conservation. After indicating the meaning of activities undertaken to protect nature, despite emerging dilemmas, the usefulness of dialogue is indicated as a tool for explaining the causes and essence of the dilemmas.
Crossing the threshold. Emerging adulthood as an elaborate liminal phase of the rite of passage
Authors: Lipska Anna , Zagórska Wanda
Published: June 2021

Abstract

The article contains a comparison of emerging adulthood (EA) to the rite of passage by van Gennep and Turner. The authors argue that EA is a far and residual equivalent of the liminal phase of the rite of passage, in its extended form. At first, they present the concept of the rite of passage, the idea of liminality, the phenomenon of extending the psychosocial moratorium and some aspects of the concept of emerging adulthood. Further they analyse the similarities and differences between the liminal phase and EA. They conclude that EA is a liminal period, but such that, on the one hand, is elaborated and extended in time, and on the other hand – degraded in its symbolism and significance (nonsanctified). The EA is associated with the specificity of western culture, such as degradation and disappearance of rites of passage in their traditional forms, orientation towards consumption and hedonism. It seems to have its source in the psychic qualities of young people, among other things, in their lack of readiness to take up the responsibility for others. Finally, the authors state that the results of a lack in initiation are thus beginning to make themselves particularly keenly felt in today’s world.

Published: June 2021

Vegetative to reproductive transition depends on different factors. This study was conducted to examine factors affecting the growth and flowering of Browallia americana L. in vitro such as the age of the sample, mineral content, plant growth regulators, concentration and type of sugar, ventilation culture. The results showed that 40-day-old shoots were a suitable source of in vitro flowering (90.85% after 45 days of culture). Mineralcontent had a great influence on the ability to differentiate flower buds of plants, the highest in Murashige and Skoog medium (87.22% after 45 days of culture). Meanwhile, most of the plant growth regulators which were surveyed in this study inhibited the flowering. In particular, culture medium with glucose showed higher flowering efficiency than saccharose, the highest flowering rate was at 50 mg/L glucoses (90.52%, with 3.50 flower buds/explant after 30 days of culture). In addition, ventilation culture, which used plastic wrapedwith milipore filter had the highest rate of flower bud formation (average 3.58 flower buds/plant). This result is an important foundation for studying the flowering of in vitro plant culture, which will be one of the great paradigm plants for teaching and basic research.

Intellectualism in Higher Islamic Traditional Studies
Authors: Hashim Rosnani
Published: June 2021

The number of faculties and universities offering Islamic traditional sciences or studies has slowly increased over the past decades. However, the Islamic community has not felt their graduates’ impact other than as teachers or religious personnel. In fact, if the criteria used to assess Islamic education is the growth of a genuine, original, and adequate Islamic thought or intellectualism, then most of these institutions have failed to provide such an education. I examine the goals and curriculum of higher Islamic education and the conditions conducive for the growth of intellectualism. I argue that poor pedagogy, which does not offer teaching methods that encourage critical and ethical thinking, contributed to the state of affairs. Further, I argue that the basic problem is the inadequate conceptualization of knowledge as regards Islamic epistemology in the curriculum and the lack of academic freedom. I assert that the issue of what knowledge is most valuable for today’s intellectual and ethical Muslims has not been resolved and that this affects the curriculum structure and, inevitably, the programs of Islamic traditional sciences. The need to reintroduce Islamic philosophy into the curriculum is one of this article’s major arguments.
The Origins and Evaluations of Hadith Transmitters in Shi`i Biographical Literature
Authors: Takim Liyakat
Published: June 2021

In this paper, I examine the provenance of the Shi`i biographical lexica on the imams’ disciples (the rijal) and propose possible reasons for the composition of these works in the eighth and ninth centuries. I then consider the authentications (tawthiqat) of those who report traditions from the imams and compare and contrast the methods of authentication in both the early and later biographical works. I also suggest possible reasons for the development of subsequent modes of authentication.
The Authentication of Hadith
Authors: Khan Israr Ahmad
Published: June 2021

Muslim scholars deserve appreciation for their invaluable contribution toward preserving the hadith literature’s authenticity. However, much more needs to be done to further strengthen its authenticity. Such great hadith authorities as Malik ibn Anas (d. 179 AH), Ahmad ibn Hanbal (d. 241 AH), al-Darimi (d. 255 AH), al-Bukhari (d. 256 AH), Muslim (d. 261 AH), Ibn Majah (d. 273 AH), Abu Da’ud (d. 275 AH), al-Tirmidhi (d. 279 AH), al-Nasa’I (d. 303 AH), al-Darqutni (d. 385 AH), and al-Bayhaqi (d. 457 AH) did their best to identify original, authentic, and valid versions of the hadiths, mainly through verifying the chain of narrators (sanad). However, they did not check the text (matn) with the same zeal. This remains the case today, even to the extent that scrutinizing the text scrutiny is considered forbidden. While further verification of hadiths is still needed, this “closed door” toward verifying the text’s validity must be opened. The present article represents an attempt to redefine the criteria for checking the texts and then applying these criteria to certain selected hadiths recorded by al-Bukhari and Muslim.

This process used acetic acid and H2O2 with mole ratio variations of olein and H2O2 of 1: 3, 1: 6, and 1: 9. The mole ratio was selected based on the analysis of iodine and oxiran numbers, which was then processed into bio grease with the addition of calcium stearate and calcium acetate. Epoxidized olein with a mole ratio of olein and H2O2 of 1: 9 was selected because it achieved the highest average oxiran number (0.99), the lowest iodine number (33.09), and it was based on ANOVA and LSD tests. The higher the oxiran number, the more epoxide compounds produced. Low iodine number indicated low unsaturation in fatty acids. The peroxy acid used in the epoxidation process reacted with unsaturated compounds, so that the lower iodine number in the epoxidized olein produced more epoxide compounds. Bio grease had a light cream color, density of 0.96 g/cm3, viscosity of 31,280 mPa.s, unworked penetration of 438 (0.1 mm), worked penetration of 443 (0.1 mm), dropping point < 26°C, corrosion resistance of 2c and NLGI number 00.

Published: June 2021

Non-terrestrial networks, including Unmanned Aerial Vehicles (UAVs), High Altitude Platform Station (HAPS) and Low Earth Orbiting (LEO) satellites, are expected to have a pivotal role in the sixth generation wireless networks. With their inherent features such as flexible placement, wide footprint, and preferred channel conditions, they can tackle several challenges in current terrestrial networks. However, their successful and widespread adoption relies on energy-efficient on-board communication systems. In this context, the integration of Reconfigurable Smart Surfaces (RSS) into aerial platforms is envisioned as a key enabler of energy-efficient and cost-effective deployments of aerial platforms. Indeed, RSS consist of low-cost reflectors capable of smartly directing signals in a nearly passive way. We investigate in this paper the link budget of RSS-assisted communications under the two discussed RSS reflection paradigms in the literature, namely the specular and the scattering reflection paradigm types. Specifically, we analyze the characteristics of RSS-equipped aerial platforms and compare their communication performance with that of RSS-assisted terrestrial networks, using standardized channel models. In addition, we derive the optimal aerial platforms placements under both reflection paradigms. The obtained results provide important insights for the design of RSS-assisted communications. For instance, given that a HAPS has a large RSS surface, it provides superior link budget performance in most studied scenarios. In contrast, the limited RSS area on UAVs and the large propagation loss in LEO satellite communications make them unfavorable candidates for supporting terrestrial users. Finally, the optimal location of the RSS-equipped platform may depend on the platform’s altitude, coverage footprint, and type of environment.

The Pedagogical Practices of an Immigrant Parent: Maintaining Heritage Language in the Home Context
Authors: Chen Emma
Published: June 2021

The maintenance of heritage language is essential to immigrant children’s linguistic, cultural, and social development. While there is a large body of literature on heritage language, how heritage language is practiced at home remains largely unknown. Engaging in an autobiographical narrative inquiry, I tell and retell stories of our pedagogical practices in the home context. I seek to bridge the research gap with new understandings of the “parent knowledge” that immigrant parents bring to bear in heritage language education. I invite you into my home and immigrant family’s language journey to witness the efforts, challenges, and rewards of learning heritage language.
Visiting Critical Exploration in the Classroom
Authors: Duckworth Eleanor
Published: June 2021

In this commentary, summarized from a recent interview, the author reminisces about a career dedicated to critical exploration in the classroom. She discusses the formation of the Moon Group, a group of teachers who met over a period of 25 years to study the behaviour of the moon. Duckworth later describes an exercise in which her students experimented with the positioning of a small mirror in the classroom in order to be able to predict where to place it on a wall so one student can see another in a different part of the room. In another exercise, she had university students observe the learning of children by having them solve spatial problems without any advice or prompts from an adult. She concludes by providing guidance for classroom teachers, emphasizing the importance of making sure, “what you want them to learn is worth learning about.”

Societal views of Deaf people typically stem from a medical or deficit perspective, which then informs educational practices. In contrast, educational settings that embrace a cultural perspective provide visual language and strategies that can benefit all students. This article will address three common myths about American Sign Language (ASL) and Deaf people and share research-supported pedagogical practices and recommendations on how to be an ally on behalf of Deaf people.
Rehumanizing Education: Teaching and Learning as Co-Constructed Reflexive Praxis
Authors: Lyle Ellyn , Caissie Chantelle
Published: June 2021

Teaching and learning are profoundly personal experiences, yet systems of education often prioritize ubiquitous agendas that alienate rather than engage. Creating space for individuals and their lived experiences has the capacity to transform the classroom from a place of containment to one of expansiveness. Resisting the tendency of education to think dichotomously about teaching/learning, theory/practice, and self/other, we engage here as two learners who happen to have shared a graduate program, one as teacher and one as student. Influenced by post-qualitative inquiry (St. Pierre, 2017a; St. Pierre, 2017b) and post academic writing (Badley, 2019), we engage reflexively to consider the experience of this shared learning journey.
