Psychological skills of Indian Gymnasts
Authors: Ghosh Amit
Published: December 2020

Psychological skills account for significant amounts of athletic performance. Studies reveal that the good performers are good in psychological skills as compared to poor performers. So in the light of this, present study assessed level of psychological skills in relation to Indian
gymnasts performance, using Psychological Skills assessment scale questionnaire which measured the skills such as imagery, self-awareness, self-confidence, attention, motivation, arousal regulation, goal setting and psychic energy management, the data collected from artistic gymnasts from
different universities those who participated in inter varsity championship in patiala, 2010. The athlete sample comprised 28 above average gymnasts and 42 below average (age range 17 to 27 yrs.). Analyses revealed that there is no significant difference among the above average and below average
gymnasts. Whereas studies show that, high potential athletes have high psychological skills-level. Though, in present study the above average gymnasts did not report any amplitude in the psychological skills. The reason could be the casual approach towards filling the questionnaire and inability
of the subjects to understand the statements of the questionnaire due to the poor understanding of the Hindi and English language as the mother tongue of the subjects were different.

Published: December 2020

In this research, the effects of individual and group learning activities on perceptions of block-based programming self-efficacy and attitudes towards robotic programming were tried to be determined. The research was conducted in a private school located in Sariyer, district of Istanbul province in the 2nd academic year of 2018-2019 with 32 students from 7th Grade. The study fulfilled as a semi-experimental pattern on the experimental and control groups using the pretest-posttest design. According to the research results, individual and group learning did not affect secondary school students’ perceptions of block-based programming self-efficacy and attitudes towards robotic programming. In addition to this, an increase was found in the perceptions of block-based programming self-efficacy in the experimental and control groups, and the attitudes towards programming of programming of the experimental group students. It was concluded that there was no significant difference between age, gender, taking aScratch lesson, writing a computer program with Scratch, and taking a robotic-programming lessons before. While robotic attitudes of students did not differ significantly according to their age and previous status of taking robotic coding courses, however, they differed significantly according to gender and male students had higher attitudes towards robotic programming than female students.

Authors: G Martelotto Luciano
Published: December 2020

This protocol is the result of the combination of various nuclei isolation protocols for single cell RNA-seq experiments using droplet-based methods, hence the name Frankenstein. Developed to prepare nuclei isolates from small sample sizes (as little as a grain of rice), this protocol uses FACS to identify cell subpopulations based on ploidy (e.g. tumor versus stroma), to ensure that nuclei suspensions are not clumped, and to remove any debris, especially ambient RNA, to help reduce background. The reference protocols can be found in the following papers: Hu, et al., Habib, et al. (2016), Habib, et al. (2017), Lake, et al., and Lacar, et al. This protocol has been validated in the Single-Cell Innovation Lab (UMCCR) and other labs worldwide for single nuclei experiments using 10x Genomics technologies. The protocol has been demonstrated to work successfully with fresh, snap/flash frozen, cryopreserved cells, and cell lines, as well as various solid cancers: pancreas, pheochromocytomas, paragangliomas, breast cancer, lymphoma, xenografts and other samples types. Cardiomyocytes can be really difficult to prepare but we have successfully prepare this. Get in touch for some tips.

Authors: MUSTAPHA Mulikat , ODEDIRAN Deborah
Published: December 2020

Parents play a fundamental role in the
upbringing of healthy and well balanced children. Sometimes these individuals
whose union has bring into existence these youngsters are separated by divorce,
work, death, abandonment among others leading the children to live with only a
parent or guardian. This inquiry explores how the self-worth of in-school
adolescents from separated families is impacted by the degree of parent
education, the basis of separation and their custodians.  The researcher utilised the descriptive
survey design. Simple random sampling technique was utilised to select two
schools each from Ilorin, East, South and West LGAs respectively, making 6
schools all together. Three hundred respondents from separated families were purposively
selected through consultation with school counsellors. The instrument used is
an adapted form of Rosenberg measure of self-worth, which was validated and
tested for consistency yielding co-efficient of 0.67. The study considered the flexibility
of the self-worth of the in-school adolescents from separated families. Data amassed
were subjected to analyses employing the Analysis of Variance. The outcomes of
the inquiry revealed that the self-worth of the adolescents from separated
families was undesirably affected particularly where their parents lack formal
education. Similarly, the self-worth of respondents from parents whose unions
have been legally dissolved was far worse. School counsellors should
identify in-school adolescents from separated families particularly those from
parents with no formal education and those from divorced parents and develop
intervention strategies to assist them develop healthy and high self-worth.
Also, counsellors should focus on refining the quality of parenting among
single parents to help them lift the self-worth of their children/wards.

Metafor kısaca bir nesneyi başka bir şeyle benzeştirerek tanımlama olarak açıklanabilir. Metaforlar karmaşık, soyut kavramları, büyük düşünce sistemlerini bir tek kelime ile ifade edebilme becerisine sahip olduğu için araştırmacılara büyük imkânlar sunmaktadır. Bu araştırma okul öncesi öğretmeni adaylarının öğretmen kavramına ilişkin algılarını metaforlar aracılığıyla saptama amacıyla gerçekleştirilmiştir. Araştırmaya 124 okul öncesi öğretmen adayı katılmıştır. Öğretmen adaylarından “Öğretmen …… gibidir, çünkü ………” ifadesini yazılı olarak doldurmaları istenmiştir. Toplanan verilere içerik analizi uygulanmış ve analiz sonucunda 88 çeşit metaforun 6 temel kategoride toplandığı saptanmıştır. Bu kategoriler, Eğitici/öğretici/yol gösterici olarak öğretmen, sevgi ve güven yansıtan öğretmen, şekillendirici/biçimlendirici olarak öğretmen, model olan öğretmen, zıt duygulanım, olumsuz duygulanımdır. Öğretmen adayları en fazla Eğitici/ öğretici/ yol gösterici olarak öğretmen kategorisi için metafor üretmişlerdir. Öğretmen adaylarının belirlediği metaforların Milli Eğitim Bakanlığı’nın belirlediği öğretmen yeterliklerine göre dağılımda ise 43 metaforun öğretmenin mesleki bilgi ve becerisine, 45 metaforun ise öğretmenin tutum ve değerlerine yönelik olduğu belirlenmiştir.

Authors: Gornostaev S.V. , Pozdnyakov V.M.
Published: December 2020

Objectives. The article describes an attempt to overcome the contradictions in the theory of loyalty by applying the traditional Russian approaches which have been successfully used for solving of scientific problems which are contiguous with loyalty.
Background. The study is necessary for the formation of a unified conceptual base for further systematizing of research of loyalty and comparison of their results.
Methodology. Based on provisions of the activity approach (L.S. Vygotsky, S.L. Rubinstein, A.N. Leontiev, А.V. Petrovsky etc.), a conceptual solution of the loyalty problem is proposed. Integrative conception of loyalty as a person’s participation in group at interconnected levels of self-determination, group emotions, as well as motivation, orientation and processes of group activity was developed by implementation of category of “activity” into a theoretical analysis. It has allowed to consider the psychological and behavioral aspects of loyalty, as well as its individual and social levels, in a holistic way within the framework of the general loyalty concept. It allowed developing the general concept of loyalty with provisions concerning system-forming factors of loyalty, dynamics and mechanisms of its development, ways of its diagnostics and correction, and possibility of coexistence of loyalties.
Conclusions. The paper argues the consideration of the leading activity of the group as a system-forming factor of loyalty. A general conclusion about possibility of applying the activity approach for research of loyalty is done.
The Dynamics of Information Search Queries about COVID-19 at the Self-Isolation Stage
Authors: Belinskaya E.P. , Stolbova E.A. , Tsikina E.O.
Published: December 2020

Objective. Studying the dynamics of information search queries in the situation of experiencing an objective global threat-the spread of COVID-19.
Background. The pandemic situation is specific because of its universality, uncertain duration and weak predictability of disease manifestations, which suggests the cumulative nature of this stressor. The uniqueness of its socio-psychological consequences is determined by the experience of self-isolation in a virtual space. The dynamics of search queries in large random samples may reflect both the reaction of the population to the statements of power subjects, and the presence of certain mechanisms of emotional self-regulation.
Study design. We analyzed search queries thematically related to the spread of COVID-19 and the introduction of self-isolation mode: 5 million search queries were randomly selected from the database, 1 million for each of the analyzed time intervals.
Participants. The study was conducted on users of the Yandex search engine.
Methods. Quantitative methods of the Data Mining class were used for data collection. Qualitative methods of the Data Mining class and contextual analysis were used for data analysis. Microsoft Excel tools were used for statistical code processing.
Results. The number of information requests on the topic of the pandemic increased sharply after V. Putin’s first address, and then steadily decreased, but the overall picture of the content dynamics of search queries, depending on official statements of the authorities, was not observed; requests about the current level of morbidity are constantly presented to the greatest extent, and to the minimum-about the possibilities of psychological assistance and the state of the Russian economy. During the whole time of the study the contents of the Internet search shifted towards positive emotional information.
Conclusions. To the maximum extent, the relationship between the experience of a pandemic and self-isolation with the nature of search queries manifests itself at the initial stages and tends to decrease in the future. The dynamics of the content of requests is ambiguously related to official statements of power subjects, influenced by the effect of counter-regulation.
The Importance of Civil, Ethnic and Regional Identity for Residents from Small Russian Towns and its Determinants
Authors: Gritsenko V.V. , Ostapenko L.V. , Subbotina I.A.
Published: December 2020

Objective. The objective of the study is to analyze the subjective significance attached by residents of small towns to civil, ethnic and regional identities and to identify its determinants.
Background. The growth of uncertainty and social and economic instability in society actualize the processes in the social identification of the person. Under these conditions the study of civic, ethnic and regional identities of residents from provincial towns in the Russian Federation as an important resource for group solidarity is of particular importance.
Study design. The authors rely on H. Tajfel and J. Turner’s theory of social identity. We conducted a survey among residents in the town Belev, Tula region, and the town Staritsa, Tver region, characterized by mono-ethnicity, negative demographic dynamics, remoteness from the capital and its regional centers.
Participants. The study involved 600 ethnic Russians (50.8% women). The quota sample in both towns included three age groups: 16—29 years old, 30—49 years old, 50 and older, each group included 100 people.
Measurements. The questionnaire was developed and tested at the Institute of Ethnology and Anthropology, Russian Academy of Sciences. The questions are aimed at determining the identification degree of respondents with various social groups, as well as assessing satisfaction with various aspects of life and confidence in their own future and the future of their town. For data processing we used methods of descriptive statistics, Student’s t-test, multiple regression analysis, SPSS 18.0.
Results. We have found high rates of subjective significance of civic, ethnic and regional identities for respondents. Moreover residents of small towns identify themselves more with representatives of their folk, less with residents of their town/region and even less with citizens of their country. The determinants of the subjective significance in the investigated types of identity for old people are satisfaction with various aspects of life, while residents in town Belev have unlimited love for their native town, pride and faith in its future prosperity.
Conclusions. The study showed that residents of small towns are looking for reliance, support and protection, primarily in identification with their ethnic group. The resource for maintaining positive self-determination is also regional identity. Moreover regional identity in this case plays an important consolidating role acting as a mechanism for the social integration of civil society.

Authors: Goran Petrus Kerowe , Setijadi Eko
Published: December 2020

The antenna performance is seen from the S-parameter value. The S-parameter graph can be seen as the return loss (S11, S22) and the mutual coupling (S21, S12) value. This research focuses on analyzing mutual coupling on Square and Vivaldi array antennas using the ring metamaterial method. The value of mutual coupling is considered very important to analyze because it affects the performance of the antenna in which is arranged in an array. The simulation results of the mutual coupling value obtained on a square array antenna use a ring metamaterial is -17 dB at a frequency of 2.4 GHz. Meanwhile, the Vivaldi array antenna uses a ring metamaterial that produces a mutual coupling value of -13.840744 dB at a frequency of 3.0162 GHz. The factors that affect the square array antenna so that it becomes the best to suppress the mutual coupling value between antenna elements are a selection of metamaterial shape and proper placement between the antenna array elements is arranged horizontally.

This work was carried out for the quantitative estimation of phenolic compounds (soluble phenolic compounds, flavonoids such as quercetin, cynaroside, and avicularin) and ascorbic acid level in the aerial plant parts (leaves and stems) of two sage species viz., Salvia tesquicola (dry-steppe sage) and Salvia verticillata (lilac sage) grown in Tatarstan and Crimea, Kazan, Russia respectively. The highest content of phenolic compounds and the ascorbic acid level was reported in the leaves, while the value of these chemical constitutes was lowest in the stems of both species. Further, it has been shown, that these plants are rich in all investigated chemicals but among these Cynaroside and avicularin are the predominated flavonoids (cynaroside, quercetin, and avicularin). The amount of all studied active compounds differed significantly and it depends on the plant organs, species, and place of growth. Further, the results of the study revealed that the content of soluble phenolic compounds in sage plants did not depend on the species and place of growth while the growing conditions had a greater impact on the amount of flavonoids and vitamin C contents.

Authors: Kurysheva N. I.
Published: December 2020

Topical and systemic carbonic anhydrase inhibitors (CAIs) are widely used in the treatment of glaucoma for reducing intraocular pressure. This part of the review describes the characteristics of systemic CAIs, their side effects and the ways to overcome them, as well as contraindications. The use of CAIs during pregnancy is considered. Particular attention is paid to the antioxidant activity of CAIs and the promising development of hybrid forms based on the existing CAIs as a part of a multipurpose glaucoma treatment strategy.

Purpose: to study the antioxidant system and lipid status of serum and evaluate the effect of Cytoflavin on these characteristics in patients with progressive and stable primary open angle glaucoma (POAG).

Patients and methods. 67 patients with advanced stage POAG were observed. The average age was 66.3 ± 1.5 years. According to the course of the glaucoma process all patients were randomized into 2 groups: the 1st group with the stable glaucoma (31 patients) and the 2nd group with rapidly progressive glaucoma (36 patients). The progression criteria of POAG were global ganglion cell loss volume (GLV) and perimetric index (mean deviation-MD). For assessment of the reactivity of the vascular endothelium, a test with reactive hyperemia was performed using ultrasound method. The assessment of oxidative stress (OS) including peroxides, malonyldialdehyde (MDA) and the total antioxidant capacity of serum (AOS) were evaluated. The investigations of lipid metabolism included the level of cholesterol total (CT), cholesterol of low-density lipoproteins cholesterol (LDL-C), high-density lipoproteins cholesterol (HDL-C), triglycerides (TG) and atherogenic index (AI).

Results. In the 2nd group there was the significant decrease of the mean GLV indices compared to those in the 1st group (7.16 ± 2.5 и 1.06 ± 0.2, respectively, р < 0.001). The mild degree of endothelial dysfunction (ED) predominantly was detected in patients of the 1st group (69 % of cases). The moderate and marked ED were found in patients with progressive POAG (68 and 25 %, respectively). The high level of OS in serum was determined in 43 % of patients of the 1st group and in 69 % of patients of the 2nd group (significant increase of peroxides and MDA). In patients with progressive POAG the mean indices of lipid metabolism (CT, LDL-C, HDL-C, TG, AI) were significantly higher than in healthy subjects (р < 0.001). Cytoflavin had a positive effect on the vascular endothelium function, normalization of lipid metabolism and decrease of OS in serum with increasing AOS in patients with progressive POAG.

Conclusion. The assessment of the indices of OS, AOS and lipid metabolism enable us to determine the risk of progression of POAG and evaluate of the effectiveness of treatment.

Purpose: tо evaluate effectiveness of cataractogenesis prophylaxis in patients with epiretinal membrane (ERM) after vitrectomy based on the pirenoxin use.

Patients and мethods. The study included 72 patients (64.5 ± 6.4 years old; 31 men, 41 women) with ERM before and after 25G microinvasive vitrectomy with removal of ERM. The 1-st group patients (36 eyes) received pirenoxin instillation (Catalin®; 3 times a day, 6 months) in addition to the standard pharmacological support. The 2-nd group patients received only standard therapy. All patients underwent: standard ophthalmologic examination; lens state photoregistration with an assessment of lens opacities intensity (LOCS-III classification) with the calculation of the cataract development index (CDI). These were control points: examination before vitrectomy and 5 months after surgery. At control points, the incidence of lens opacities in the observation groups was also evaluated. Statistical analysis included: calculation of the mean and its standard deviation (M ± s); assessment of the significance of differences in control points with each group (Wilcoxon's T-test) and between groups (Mann—Whitney U-test); Pearson xi-square test.

Results: In the 1-st group (pirenoxin instillation), 6 months after vitrectomy and ERM removal, the following indicators were noted: the initial cataract incidence was 5.6 %; CDI — 0.36 ± 0.03 points, increasing the maximum corrected visual acuity (MCVA) from 0.31 ± 0.03 to 0.6 ± 0.05. In the 2-nd group similar indicators significantly differed from the 1-st group data: the initial cataract incidence was 36.1 % (Pearson xi-square test > 3; p < 0.05); CDI — 3.1 ± 0.3 points (p < 0.01); the MCVA increase from 0.3 ± 0.05 to 0.43 ± 0.1 (p < 0.05).

Conclusion. Pirenoxin (Catalin®) has demonstrated quite high efficacy in the cataract prevention in patients after vitrectomy with ERM removal.

Published: December 2020

Production
of friction particulate ceramic matrix composites (PCMCs) by powder metallurgy
method was carried out using iron 105 μm millscale, 50 μm silica sand, 80 μm magnesia and 53 μm bentonite
clay as input materials. Different formulation of the blend of these materials
were prepared and the composites were produced. Microstructural, water absorption,
and mechanical characterisation were determined using standardised methods. The ceramic composites exhibited very good
properties in terms of density, water
absorption, hardness, compressive strength, shear strength and impact energy.
The specific values of these properties exhibited by sample D in terms of density (1.87 g/cm3), water absorption (0.3 %) indicating reduced
pores/voids,
hardness (147.09 BHN), compressive strength (156.45 MPa), shear strength (5.97
MPa) and impact energy (7.62 J) are desirable. The
uniform dispersion of the particles as observed in the microstructure and
strong bonding/adhesion contributed to the enhancement of the properties. These results compared favourably
well with that of conventional automobiles brake pads which is an indication that the composites are very suitable for application as
automobiles brake pads.
ASTROPHYSICAL AND STRUCTURAL PARAMETERS, AND DYNAMICAL EVOLUTION OF THE OPEN CLUSTERS NGC 1245 AND NGC 2099

Published: December 2020

We derive astrophysical and structural parameters of open clusters NGC 1245 and NGC 2099 from 2MASS JHKs and Gaia DR2 photometric / astrometric data bases. Their likely members have been determined from Gaia DR2 proper motion data. Our E(B – V) values (2MASS) are slightly smaller than the literature values, whereas our E(B – V) values (Gaia DR2) agree with the literature within the uncertainties. Their distance moduli/distances and ages are in good coincident with the literature. NGC 1245 has steep negative core mass function slope (MFs) (χ_core=-1.24). It’s at halo (χ_halo=+0.78) and at overall (χ_overall=-0.95) MFs mean that it presents signs of small-scale mass segregation to the outer regions from its core, due to its [t_rlx (overall),τ_overall ]=[302 Myr,5]. The MFs of NGC 2099 is very negative steep (χ_core=-2.67) in the core, and quite positive steep (χ_halo=+1.41) in the halo. This kind of MF slope steeping from the core to the outskirts indicates that low-mass stars in the core are transferred to the cluster's outskirts, while massive stars sink in the core, because of mass segregation. NGC 2099's flat overall MFs (χ_overall=+0.91) and its τ_overall=8 presents a sign of mass segregation. These OCs with the relatively large masses 8700 Msolar (NGC 1245) and 5660 Msolar (NGC 2099), which locate at RGC > 9 kpc, expose to external perturbations such as tidal effects and shock waves, and they lose their stars in low-proportions.
DIFFERENTIAL CROSS SECTIONS FOR ELASTIC SCATTERING OF ELECTRONS FROM MOLECULAR NITROGEN
Authors: ÖZER Zehra Nur
Published: December 2020

In the field of molecular collisions, there has been a kind of rebirth with respect to the scattering of electrons both experimentally and theoretically. From experimental point of view, most data are available only in a limited energy and angular range. From theoretical side, new and different models have been developed and experimental data is needed to test these theoretical models. The basic concept in elastic scattering of electrons from atoms and molecules is the differential cross section. As a function of scattering angle and electron impact energy the cross sections can be measured and these results reveal important information about projectile, target and also about the atomic and molecular structures. In this work experimentally measured differential cross sections (DCSs) for elastic scattering of electrons by molecular nitrogen are presented.

Make 21st Century Education: The Importance of Teaching Programming in Schools
Authors:   The University of Georgia, Tbilisi, Georgia, Abesadze Shorena , Nozadze David
Published: December 2020

During recent years, there are huge discussions regarding 21st century education; Experts, scientists, educational specialists offer different ideas, results, and conclusions about how to improve educational processes in schools and how to develop students' 21st century skills; one of the important steps that have been taken in this direction is to introduce programming (coding) from the first grade as an independent subject in schools. The goal of this paper is to find out why it is important to teach programming in school. The main questions about this issue are: what are the reasons to teach programming? What are the main problems in the teaching process? How to teach programming? Answers to these questions are not always connected with each other and the teachers, who really create education in the classroom, need much more precise and complete information to what to teach and how to teach. Because of these issues, we decided to research this field and share our own experience, which we believe is successful in our school: we teach programming through the project-based learning method. Using this method, it is possible to develop 21st century skills and teach the basics of computer science from elementary school. In this paper we will discuss about secondary school students; by the end of the project, the 10th grade students have solved one of the problems of the school community - they have created educational games on the topic of ecology; games were created by the request of elementary school teachers; this year the games are successfully used in learning process.

Axiological aspects of targeting coordinated activities in various types of organizational systems are described. The article analyzes the features and role of ownership rights to natural and intellectual resources by the implementation of the concept of sustainable development in the social state. The features of the implementation of property rights to natural and intellectual resources in the context of the implementation of the concept of sustainable development of the social state are analyzed. The role of property relations in the initiation and coordination of purposeful activity of economic agents in the space of national development has been determined.

Conclusions and Relevance: The results of the study allow us to formulate a number of conclusions. Firstly, further improvement of the methodology of strategic management should be carried out in the context of the interrelated modernization of national models of economy, development and management. Secondly, the advance of methods and tools for substantiating long-term development goals should take into account the axiological foundations of goal-setting. And third, digital transformation allows to differentially describe the motivational function of public ownership by natural and intellectual resources of development.
