A Systematic Study of the Best Fitting Line Problem
Authors: Gambirasio Giorgio , Consonni Denise
Published: July 2021

AbstractThe classical approach for tackling the problem of drawing the 'best fitting line' through a plot of experimental points (here called a scenario) is the least square process applied to the errors along the vertical axis. However, more elaborate processes exist or may be found. In this report, we present a comprehensive study on the subject. Five possible processes are identified: two of them (respectively called VE, HE) measure errors along one axis, and the remaining three (respectively called YE, PE, and AE) take into consideration errors along both axes. Since the axes and their corresponding errors may have different physical dimensions, a procedure is proposed to compensate for this difference so that all processes could express their answers in the same consistent dimensions. As usual, to avoid mutual cancellation, errors are squared or taken in their absolute value. The two cases are separately studied.In the case of squared errors, the five processes are tested in many scenarios of experimental points, both analytically (using the software Mathematica) and numerically (with programs written on Python platform employing the Nelder-Mead optimization method). The investigation showed the possible existence of multiple solutions. Different answers originating from different starting points in Nelder?Mead correspond to solutions revealed by analytic search with Mathematica. For each scenario of experimental points, it was found that the best lines of the five processes intercept at a common point. Furthermore, the point of intercept happens to coincide with the 'center of mass' of the scenario. This fact is described by stating the existence of an empirical 'Meeting Point Law'. The case of absolute errors is only treated numerically, with Nelder?Mead minimizer. As expected, the absolute error option shows greater robustness against outliers than the square error option, for all processes. The Meeting Point Law is not valid in this case.By taking the value of minimized error as a criterion, the five processes are compared for efficiency. On average, processes PE and AE, that consider errors along both axes, resulted in the smallest minimized error and may be considered the best processes. Processes that rely on errors along a single axis (VE, HE) stay at the second place. In all cases, YE is the process that results in the largest minimized errors
Visual Argument Structure Tool (VAST)
Authors: Leising Daniel , Grenke Oliver , Cramer Marcos
Published: July 2021

We present the first version of the Visual Argument Structure Tool (VAST) which may be used for jointly visualising the semantic, conceptual, empirical and reasoning relationships that constitute arguments. Its primary purpose is to promote exactness and comprehensiveness in systematic thinking. The system distinguishes between concepts and the words (“names”) that may be used to refer to them. It also distinguishes various ways in which concepts may be related to one another (causation, conceptual implication, prediction, transformation, reasoning), and all of these from beliefs as to whether something IS the case and/or OUGHT to be the case. Using these elements, the system allows for formalisations of narrative argument components at any level of vagueness vs. precision that is deemed possible and/or necessary. This latter feature may make the system particularly useful for attaining greater theoretical specificity in the humanities, and for bridging the gap between the humanities and the “harder” sciences. However, VAST may also be used outside of science, to capture argument structures in (e.g.) legal analyses, media reports, belief systems, and debates.

[Note: This paper is in press at Scholarship of Teaching and Learning in Psychology]. Recently, there has been a growing emphasis on embedding open and reproducible approaches into research. One essential step in accomplishing this larger goal is to embed such practices into undergraduate and postgraduate research training. However, this often requires substantial time and resources to implement. Also, while many pedagogical resources are regularly developed for this purpose, they are not often openly and actively shared with the wider community. The creation and public sharing of open educational resources is useful for educators who wish to embed open scholarship and reproducibility into their teaching and learning. In this article, we describe and openly share a bank of teaching resources and lesson plans on the broad topics of open scholarship, open science, replication, and reproducibility that can be integrated into taught courses, to support educators and instructors. These resources were created as part of the Society for the Improvement of Psychological Science (SIPS) hackathon at the 2021 Annual Conference, and we detail this collaborative process in the article. By sharing these open pedagogical resources, we aim to reduce the labour required to develop and implement open scholarship content to further the open scholarship and open educational materials movement.

Published: July 2021

Background. Individuals with Tourette syndrome (TS) often report that they express tics as a means of alleviating the experience of unpleasant sensations. These sensations are perceived as an urge to act and are referred to as premonitory urges. Premonitory urges have been the focus of recent efforts to develop interventions to reduce tic expression in those with TS. Increasing evidence points to the role of both structural and functional alterations of prefrontal and limbic brain regions regarding the experience of premonitory urges to tic in TS. This study examined the contribution of brain GABA and glutamate levels of the right primary sensorimotor cortex (SM1), supplementary motor area (SMA), and insular cortex (insula) to tic and urge severity in children with TS.Methods. Edited magnetic resonance spectroscopy was used to assess GABA+ (GABA + macromolecules) and Glx (glutamate + glutamine) of the right SM1, SMA and insula in 68 children with TS (MAge = 10.59, SDAge = 1.33) and 41 typically developing controls (MAge = 10.26, SDAge = 2.21). We first compared GABA+ and Glx levels of these brain regions between groups. We then explored the association between regional GABA+ and Glx levels with urge and tic severity. Results. GABA+ and Glx of the right SM1, SMA and insula were comparable between the children with TS and typically developing controls. In children with TS, lower levels of SMA GABA+ was associated with more severe and more frequent premonitory urges. Neither GABA+ nor Glx levels were associated with tic severity. Conclusions. These results broadly support the role of GABAergic neurotransmission within the SMA in the experience of premonitory urges in children with TS.
The role of social context in the association between leisure activities and romantic relationship quality
Authors: Dobson Kiersten , Ogolsky Brian G
Published: July 2021

Shared leisure activities with one’s romantic partner are beneficial for both partners and their romantic relationship, but may not exclusively occur with only the partners present. The current research examines the impact of leisure and other relationship behaviors in various social contexts on romantic relationship quality (satisfaction and commitment). Data were collected from a representative sample of couples over the course of nine months (N=232 couples at Phase 1), including two 10-day daily diaries documenting engagement in 59 behaviors across various social contexts. Results demonstrated that leisure with one’s partner (without others) was positively associated with short-term relationship quality, whereas leisure with others (without one’s partner) was negatively associated with relationship quality; leisure with one’s partner and others and leisure alone were not associated with relationship quality. When considering engagement in other relationship behaviors with one’s partner, we found no unique effects of the rates of the behaviors, but significant effects for the proportion of physical affection relative to other behaviors. These findings suggest that the content and context of leisure have unique roles in romantic relationships.
The shallow of your smile: The ethics of expressive vocal deepfakes
Authors: Guerouaou Nadia , Vaiva Guillaume , Aucouturier Jean-Julien
Published: July 2021

Rapid technological advances in artificial intelligence are creating opportunities for real-time algorithmic modulations of a person’s facial and vocal expressions, or “deep- fakes”. These developments raises unprecedented societal and ethical questions which, despite much recent public awareness, are still poorly understood from the point of view of moral psychology. We report here on an experimental ethics study conducted on a sample of N=303 participants (predominantly young, western and educated), who evaluated the acceptability of vignettes describing potential applications of expressive voice transformation technology. We found that vocal deep-fakes were generally well accepted in the population, notably in a therapeutic context and for emotions judged otherwise difficult to control, and surprisingly, even if the user lies to their interlocutors about using them. Unlike other emerging technologies like autonomous vehicles, there was no evidence of social dilemma in which one would e.g. accept for others what they resent for themselves. The only real obstacle to the massive deployment of vocal deep-fakes appears to be situations where they are applied to a speaker without their knowing, but even the acceptability of such situations was modulated by individual differences in moral values and attitude towards science-fiction.
Quantum phenomenology as a “rigorous science”: the triad of epoché and the symmetries of information
Authors: Penchev Vasil Dinev
Published: July 2021

Huserl (a mathematician by education) remained a few famous and notable philosophical “slogans” along with his innovative doctrine of phenomenology directed to transcend “reality” in a more general essence underlying both “body” and “mind” (after Descartes) and called sometimes “ontology” (terminologically following his notorious assistent Heidegger). Then, Husserl’s tradition can be tracked as an idea for philosophy to be reinterpreted in a way to be both generalized and mathenatizable in the final analysis. The paper offers a pattern borrowed from the theory of information and quantum information (therefore relating philosophy to both mathematics and physics) to formalize logically a few key concepts of Husserl’s phenomenology such as “epoché” “eidetic, phenomenological, and transcendental reductions” as well as the identification of “phenomenological, transcendental, and psychological reductions” in a way allowing for that identification to be continued to “eidetic reduction” (and thus to mathematics). The approach is tested by an independent and earlier idea of Husserl, “logical arithmetic” (parallelly implemented in mathematics by Whitehead and Russell’s Principia) as what “Hilbert arithmetic” generalizing Peano arithmetics is interpreted. A basic conclusion states for the unification of philosophy, mathematics, and physics in their foundations and fundamentals to be the Husserl tradition both tracked to its origin (in the being itself after Hidegger or after Husserl’s “zu Sache selbst”) and embodied in the development of human cognition in the third millennium.
Nose-down saddle tilt improves gross efficiency during seated uphill cycling
Authors: Wilkinson Ross D. , Kram Rodger
Published: July 2021

Riding uphill presents a challenge to competitive and recreational cyclists. Based on only limited evidence, some scientists have reported that tilting the saddle nose down improves uphill-cycling efficiency by as much as 6%. Purpose: Here, we investigated if simply tilting the saddle nose down increases efficiency during uphill cycling, which would presumably improve performance. Methods: Nineteen healthy, recreational cyclists performed multiple 5-min trials of seated cycling at ~3 W kg–1 on a large, custom-built treadmill inclined to 8° under two saddle-tilt angle conditions: parallel to the riding surface and 8° nose down. We measured subjects’ rates of oxygen consumption and carbon dioxide production using an expired-gas analysis system and then calculated their average metabolic power during the last two min of each 5-min trial. Results: We found that, compared to the parallel-saddle condition, tilting the saddle nose down by 8° improved gross efficiency from 0.205 to 0.208 –– an average increase of 1.4 ± 0.2%, t = 5.9, p < .001, CI95% [0.9, 1.9], ES = 1.3. Conclusion: Our findings are relevant to competitive and recreational cyclists and present an opportunity for innovating new devices and saddle designs that enhance uphill cycling efficiency. The effect of saddle tilt on other slopes and the mechanism behind the efficiency improvement remain to be investigated.
Religiöse Bildung als Dimension Globalen Lernens
Authors: Simojoki Henrik
Published: July 2021

Die anfängliche Durchlässigkeit zwischen den Diskursen um Globales Lernen und religiöser Bildung ist in den vergangenen Jahrzehnten einer wachsenden Entkoppelung gewichen. Vor diesem Hintergrund argumentiert der Beitrag, dass bildungswissenschaftliche und religionspädagogische Perspektiven auf Globales Lernen aufeinander verwiesen sind. Um die wechselseitige Anschlussfähigkeit gesellschaftstheoretisch zu unterlegen, eröffnet er zunächst – unter Rückgriff auf einschlägige Entwürfe von Roland Robertson und Peter Beyer – kulturwissenschaftliche und systemtheoretische Zugänge zur fortschreitenden Globalisierung von Religion in der Weltgesellschaft. Anschließend wird die Relevanz der religiösen Bildungsdimension für Globales Lernen an drei aktuellen Bewährungskontexten (COVID-19-Pandemie, globale Migration, Digitalisierung) exemplarisch ausgewiesen.
Grenzüberschreitend Theologie treiben: Zur Nachhaltigkeit religiöser Bildung am Beispiel internationaler Studienreisen im Kontext theologischer Hochschullehre
Authors: Könemann Judith
Published: July 2021

Im Kontext der theologischen Hochschullehre sind die Möglichkeiten globalen Lernens noch vergleichsweise unerforscht, obwohl gerade Theologie in ihrer weltkirchlichen Ausrichtung Anknüpfungspunkte für solche Lern- und Bildungsprozesse liefert. Der folgende Beitrag verfolgt ein doppeltes Ziel: Zum einen wird der Frage nachgegangen, inwieweit im Rahmen universitärer Lehrveranstaltungen Ziele des globalen Lernens erreicht werden können und zum anderen, inwieweit solchen Erfahrungen Nachhaltigkeit zukommt. Gegenstand der Untersuchung sind die Evaluationen zweier Hauptseminare mit Exkursionen ins außereuropäische Ausland. Im Mittelpunkt der Untersuchung steht der spezifische Zusammenhang von Exposure-Erfahrung als Form Globalen Lernens, (christlicher) Religion und Nachhaltigkeit.
On the question of the ideological foundations of traditional Japanese culture
Authors:   INION RAN, Skvortsova Elena
Published: July 2021

The article is devoted to the analysis of the phenomenon of the tea ceremony and its main concept of wabi, without which it is impossible to understand the ideological foundations of Japanese spiritual culture. At the same time, the basic concept in which the tea ceremony is recognized and described leads to the ultimate category of the entire Far Eastern culture – Nothingness (Emptiness, nonexistence), which is crucial for understanding Japanese religions, philosophical and aesthetic thought. The article discusses the views of the founder of the Kyoto school of philosophy Nishida Kitaro (1870–1945) and some of his students on the nature of the categories of wabi and Nothingness. Also, an analysis of these categories by researchers of the second half of the 20th century, Izutsu Toshihiko and Izutsu Toyoko is given.
Vladimir Solovyov. Messianism: idea – model – testament – symbol
Authors: Tverdislowa Elena
Published: July 2021

The problem of messianism is one of the most relevant and confusing. An integral component of Soloviev’s project of unity, messianism is considered as a connecting thread of his religious structures within the framework of the history of ideas: God-manhood as a fact and process of unity, Judaism and Christianity, the Church as a creative force in the reunification of Churches, the construction of a theocratic state, Slavophilism as a way to the interaction of Eastern and Western Christianity, etc. Soloviev’s messianism is a multivariant and polysemantic system, it allows you to classify its components according to the characteristics that the scientist gives, without specifically designating them: idea, model, testament, symbol. The idea implies all systems and subsystems as one. Inside the idea, a model is distinguished (Jewish, Polish, Russian – not according to nationality, but according to the experience of the people), covenant (personal agreement with God: people with God, peoples among themselves), symbol – a creative image of the unity of societies, states, Churches, peoples with God, finally – the Jewish and Christian religions. Based on the analysis, it can be concluded that Soloviev’s messianism is a cross-cutting concept of the doctrine of all-unity, in which the philosopher’s thought found evolution and development.
Music journalism of the first half of the 19 th century about the Russian violin school
Authors:   INION RAN, Gudimova Svetlana
Published: July 2021

Since the beginning of the XIX century the Russian press informs its readers about all musical events. Although the authors of the publications were not professionals, the level of reviews and notes amazes with their knowledge of art, especially knowledge of the intricacies of violin playing. This phenomenon can only be explained by the rich auditory experience of journalists. In Russia there was an intense musical life, the most famous virtuosos of that time performed in salons and on stages not only in capitals, but also in provincial cities. By the beginning of the 19th century a strong Russian violin school was formed with an original («vo-cal») interpretation of sound. Its representatives pay much more attention to the quality of sound than foreign virtuosos, who prioritize technical perfec-tion, sometimes to the detriment of even the elementary requirements of musicality. Russian music criticism has never echoed the opinions of Western colleagues; it had its own criteria for evaluating it. She boldly criticized even the violinists-buffooners recognized in Europe and supported the Rus-sian virtuosos, who soon gained worldwide recognition.

«Chance, an instant instrument of Providence»: about the cultural and historical background and parallels of Pushkin’s aphorism
Authors:   INION RAN, Dushenko Konstantin
Published: July 2021

The convergence of chance and Providence was common in the literature of the eighteenth and first decades of the nineteenth centuries, however, Pushkin poses this problem in a historiosophical context. Pushkin’s aphorism «Chance, the mighty, instant instrument of Providence» had a number of parallels in French literature, including the works of conservative publicists of the 1800-1820 s. The opinion that Pushkin is polemicizing here with French historians of the Restoration era is not sufficiently substantiated. The expression «formula of history», which plays an important role in Pushkin’s notes, belongs to french traditionalist P.S. Ballanche, but the concept of «providential hasard», introduced by Ballanche, to Pushkin, apparently, was not known. The article also considers the most famous aphorisms from the close semantic series: «Chance is a nickname for Providence» (N. Chamfort), «Chance is the pseudonym of God» (T. Gautier) etc.

Passport and biological age of students of the Faculty of Biology and Natural Sciences: a comparative analysis
Authors: Voloshin O.R. , Kopko I.E.
Published: July 2021

The article discusses the problem of behavior and improving the health of students. According to the results of many studies, in recent years there has been a tendency among students to reduce their level of health and physical activity. There are many methods for assessing health, such as the method of determining biological age.

The aim of the study is to compare student passports and their biological age. The study was conducted on the basis of the Faculty of Biology and Natural Sciences of DSPU. Ivan Franko, which was attended by 43 students of I-IV courses. The following research methods were used to determine the biological age: testing; questionnaires, observations; methods of generalization, synthesis and analysis. It was found that in comparison with senior courses, students of I-II courses have a biological age higher than the passport. As a result of obtaining information that in the vast majority of respondents who ignored a healthy lifestyle and low low level of physical activity, the actual biological age exceeded the value of the required biological age, they were characterized by accelerated aging and poor health.

Analysis of the results of the study showed that most students I-IV showed poor static coordination, decreased attention and reaction speed, as well as reduced respiratory arrest during exhalation. Based on the results of the study, a manual was developed for students with recommendations for reducing biological age.
Dynamics of indicators of physical state of athletes under the influence of training programs
Authors: Karpushin M. , Karpushin A.
Published: July 2021

This article is devoted to the implementation of an experimental program and, thus, changes in the training process of athletes to optimize their physical condition.

The ultimate goal of the study by Karpushyn Mykhailo and Oleksiy "Dynamics of indicators of physical condition of athletes under the influence of training programs" is to improve the results of athletes, optimize their physical shape with the help of updated training programs and training units. The tasks are as follows: 1. To analyze the existing situation and on this basis to form updated training units; 2. Get acquainted with the existing literature and coverage of this topic; 3. To develop an updated method of training for the studied group of athletes; 4. To study the influence of the updated program of specific training programs and blocks on the physical status of athletes. The conducted experimental study showed a positive dynamic progress in the physical fitness of the participants of the experimental group. Thus, it becomes obvious the possibility of achieving better physical condition in a shorter period of time, the qualitative development of physical shape, with the correct distribution of loads.

The conclusions after the study are obvious - a well-formed training technique in combination with an individual approach to each athlete gives a qualitatively new result: the optimal physical shape of the athlete in a short time and less traumatic. Thus, in the training process, quality is important, not quantity, which ultimately guarantees the dynamics of growth.

Purpose: The vinca alkaloids’ activity against pediatric low-grade glioma (PLGG) is well established. The
goal of the present study is to describe our experience with oral vinorelbine in patients with progressive
optic pathway glioma (OPG), not only regarding the clinical response, but also the cost benefit using an oral
medication. Methods: Patients under 21 years of age with unresectable and/or progressive OPG were
eligible. Oral vinorelbine was administered at a dose of 90mg/m2 daily on days 0, 8 and 22, in a scheme of
4 weekly cycles for a total of 18 cycles (54 doses).
Results: From 2013 to 2018, sixteen patients were enrolled onto the study, with a median age of 9,1 years
(range 4,6-17,8y). The most common histology was pilocytic astrocytoma (88,8%). Best response to
chemotherapy was reviewed with a response rate (complete, partial, or minor response) of 30% for the
patients treated exclusively with the oral drug. Five-year event-free survival (EFS) rate was 43.4%. Six
patients had to change to intravenous vinorelbine due to gastrointestinal toxicity, vomiting grade III. None
of the patients showed neurotoxicity. The total cost including drug acquisition, administration and toxicity
management was lower with the oral formulation comparing to IV one.
Conclusion: Single-agent oral vinorelbine seems to have some clinical activity in the management of
recurrent or refractory pediatric OPG, being an interesting and cost-effective option, minding that
gastrointestinal toxicity may be limiting and a combination of antiemetics should be considered in this
treatment regimen.

The Use Of Antiplatelet Review And Post Percutaneous Coronary Intervention In Private Hospital Surabaya
Authors: Rochmawati Ike Dhiah
Published: July 2021

Antiplatelets are medicines that stop cells in the blood (platelets) from sticking together and forming a clot, which may lead to a heart attack or stroke. Furthermore, the use of antiplatelet after percutaneous coronary intervention is one of the challenge encountered by the clinicians or hospital staff because it has to be calculated between the risk-benefit ratio. This study aims to evaluate the use of dual antiplatelet therapy in patients undergoing percutaneous coronary intervention. A retrospective study was used and data were obtained from patient records. The data obtained were analysed to know the relationship between age, gender, and type of drug combination associated with ischemic events. The patient demographics were analysed descriptively, and the comparison between age and sex group related to ischemic events was analysed using chi-square analysis. There was no statistical difference in ischemic events between age and sex group. The study reported that the most commonly used DAPT profile was the combination of Aspirin 100 mg - Clopidogrel 75 mg (38%) and Aspirin 100 mg - Ticagrelor 90 mg (28%). The profile of ischemic events in patients using the aspirin-clopidogrel combination was lower than that of the aspirin-ticagrelor combination.Keywords: Antiplatelet, Percutaneous Coronary Intervention, Coronary Heart Disease

Authors: Nduka Ijeoma
Published: July 2021

Background: Postnatal period is as important as pregnancy and childbirth. Half of all postnatal deaths occur during the first week after birth. During postnatal period, the mother’s body undergoes major changes from pregnancy. Therefore, there is need for continuity of care after birth to prevent and manage complications that may arise during postnatal. This study was carried out to determine factors associated with the utilisation of postnatal care services in a rural community in Abia state.
Methods: This was a descriptive cross-sectional study conducted from March 2019 to May 2019 among women living in Amuvi community in Arochukwu Local Government Area (LGA)of Abia state.  The study participants were women of reproductive age group (15-49 years) who had at least been pregnant once, carried pregnancy to full maturity and delivered at term. Data was collected using pre-tested semi-structured interviewer-administered questionnaire.
Results: Four hundred and sixty-seven (467) women participated in the study. Four hundred and forty-three (95.1%) women attended postnatal visits while 23 (4.7%) did not. Reasons given for attending postnatal care by respondents were; routine check-ups, counselling on family planning, appointment with health workers 54 (11.7%), same day appointment as child’s immunisation, child was sick.  Respondents who were married were 2 times (AOR=2.587, 95% CI:-0.878-0.120) more likely to use postnatal care services than single mothers. Mothers who had an occupation were 2 times (AOR=2.897, 95% CI: 0.051-0.267) more likely to use postnatal care services than those who did not. Husband’s occupation was statistically significant with utilisation of postnatal services.
Conclusion:  Utilisation of postpartum care services was high among women in Amuvi community of Abia state. PNC services utilisation were associated with marital status, mother’s occupation and husband’s educational status.

The research aims to analyze several biological aspects of the squeezed fish in Batutegi Lampung Reservoir. The study used an experimental method of capture used net capture tool with mesh-size 1.5-2.5 inches. Sample fish measured their total length, weighed in weight, and examined their stomachs to determine what type of food they had. We researched in February, August, and November 2017. The example of keperas fish caught amounted to 415 individuals. Analysis of long-weight relationships showed that February and August were allometrically negative, while November allometric was positive. The condition factor is worth one at each station and month.  The eating habits of squeezed fish are plants 50%, fish 15%, insects 10%, worms 9%, phytoplankton 8%, and zooplankton 8%. The growth pattern of fish squeeze in November is isometric and allometric positive due to the development of gonads. The food habits of fish keperas are omnivorous, with the composition according to food availability in the environment.
Methods of coating a three-dimensional structure with polymer electrolytes for lithium-ion batteries
Authors: Beysembaeva К , Nurymov Zh
Published: July 2021

The paper considers various methods of conformal coating the three-dimensional structure of Ni foam with polymers as electrolytes in lithium-ion batteries. Polymethylmethacrylate (PMMA), polyacrylonitrile (PAN), polyvinylidene fluoride (PVDF), and polyethylene oxide (PEO) were chosen as polymer electrolytes because of their good ionic conductivity and mechanical stability. Conformal coating was performed using two methods: drop coating, dip coating. The polymer-coated three-dimensional Ni foams were characterized by field-emission scanning electron microscopy (FE-SEM) to determine the more conformal coating method and testing the ionic conductivity of polymers. From this research, it could be concluded that the dip coating method allows a more conformal coating of the three-dimensional Ni foam structure and the polymers obtained by this method have a good value of ionic conductivity.

Published: July 2021

На сегодняшний день в местных птицеводческих хозяйствах сложилась практика, когда помет птицефабрик практически не перерабатывается, и это приводит к загрязнению близлежащих к территории фабрики почвы, воды и воздуха.  Одна из таких птицефабрик размещается непосредственно в зоне города Актобе вблизи жилых массивов, следствием чего является ухудшение условий жизни жителей ближайших районов города. Зловоние является постоянным спутником этих мест. Давно назрела необходимость внедрения экологически и экономически рациональных технологий. Авторы доказывают, что наиболее целесообразным выходом из создавшейся ситуации может быть разработка и внедрение технологии производства эффективных удобрений на основе птичьего помета, решающее проблему тяжелого экологического состояния зон размещения птицефабрик, с одной стороны, и проблему катастрофического снижения плодородия используемых в сельском хозяйстве почв, с другой стороны. В результате анализа существующих методик переработки птичьего помета был рассмотрен и предложен метод интенсивного компостирования помета нагнетанием воздуха для производства органического и органоминерального удобрений. Метод включает отдельные стадии, реализующие процессы сушки, обеззараживания, аэробной ферментации и гранулирования обогащенного птичьего помета.

The state of the visual system is part of the health of an individual. One of the most important aspects of the educational process at the university, along with obtaining a quality education, is the preservation of the health of students. Indicators of the effectiveness of the state of the visual system of students characterize the degree of adaptability of the system to the performance of the assigned tasks and are generalizing indicators of the optimal functioning of the visual system. In general, scientific studies of the visual system as a resource for information processing are developing similarly to studies of the visual analyzer. “Student health” refers to objective indicators and a subjective feeling of a complex state and harmony, characterized by good health, social well-being, and high working capacity. A survey was conducted to assess the awareness of the prevalence and knowledge of common eye diseases among the student population in the city of Kyzylorda. The results of a questionnaire survey on eye hygiene and major eye diseases are presented. Revealed the percentage of students' awareness and the state of eye health.

Molybdenum and plant resistance to viral infection
Authors:   University of Hohenheim, Yergaliev T.
Published: July 2021

Molybdenum takes an active part in several physiological processes necessary for the growth and development of plants and other domains of life. Molybdenum participates in numerous biochemical reactions and lack of this metal may affect the total amount of proteins in plants. More than fifty Mo-containing enzymes are currently known, although most of them were found in bacteria. Plants contain Mo-containing enzymes such as nitrate reductase, sulfite oxidase, aldehyde oxidase, xanthine dehydrogenase, and mitochondrial amidoxime reductase. Tungsten is another heavy metal, which due to highly similar physico-chemical properties with Molybdenum may be incorporated instead of the latest as enzyme cofactor, leading to its inactivation. In this article, preliminary results from a pilot experiment are shown, demonstrating the effect of Molybdenum and Tungsten treatment on Nicotiana benthamiana plants infected with Tomato Bushy Stunt Virus, which refers to viruses parasitizing economically important crops. This virus infects more than 100 species of monocotyledonous and dicotyledonous plants from more than 20 different families. Infection of plants with a viral infection occurs through mechanical damage to the root system; virions in this case can be transmitted through soil or water. It was found that Molybdenum treatment may lead to mitigation of otherwise fatal for the host viral infection.

Mitochondria are unique cell organoids that have their own mitochondrial DNA. They are involved in the regulation of many processes, such as cell survival, apoptosis, and cellular metabolism. It has long been known that mitochondria play a leading role in the mechanism of malignant transformation in the development of many neoplasms. Radon is a radioactive inert gas, is recognized as a carcinogen and, according to the World Health Organization, it is the second cause of lung cancer after smoking. Radon is found in soil, water and air in various concentrations. Radon migrates from the soil and rocks into the surrounding air, as a result of which it accumulates in poorly ventilated or closed rooms. Such areas represent the primary environment in which people are exposed to radioactive radon radiation. Radon penetrates through cracks in the Earth's crust and accumulates in the lower layers of the atmosphere. An increase in the concentration of radon in the air is observed in regions rich in uranium deposits, as well as near uranium mines. However, at the moment, the mechanisms of malignant transformation induced by radon are still not completely clear. In this review, we consider for the first time the most modern understanding of the role of mitochondria in the molecular and cellular effects of ionizing radiation, including radon. This kind of knowledge can be of great importance for improving the antitumor effectiveness of radiation therapy, as well as for reducing damage to healthy cells exposed to ionizing radiation and protecting the population living in an area potentially dangerous for radon manifestations.
