Authors: Kumar Ashish , Chauhan G.S.
Published: August 2020

Removal of malachite green from water bodies is an environmental concern of utmost priority. It requires adsorbents that can efficiently operate under real conditions. In view of this, a new polyacrylic acid based nano-hybrid polymer was synthesized by using sol-gel method in which acrylic acid acts as an organic part and tetraethoxysilane (TEOS) as an inorganic component. The new series of two other nano-hybrid polymers were also synthesized by using nanoparticles of iron oxide and titanium dioxide. The synthesized nano-hybrid polymers were extensively characterized using FTIR and XRD spectroscopic techniques. Further the synthesized nano-hybrid polymers were subjected to swelling studies with respect to different parameter such as time, temperature and pH. Malachite green was used as a cationic dye for studying the uptake behavior of synthesized polymers. Maximum retention capacity (MRC) and reusability of hybrid polymers were also evaluated up to ten cycles. The hybrid polymer, poly(AAc)/TEOS was more effective with high dye retention capacity.

The Theological-Eschatological Implications of Name Michael in Jude
Authors: Javien Rico Taga
Published: August 2020

The pastoral epistle of Jude is shrouded with rich theological significance, in spite of its shortness. Theological themes like order of salvation, faith, mission, worship, judgment, great controversy, second coming, and the end of the world, and others are interwoven in the fabric of Jude. It means that Jude starts with protology and ends with climactic and cosmic victorious eschatology, particularly the resurrection of the righteous.

            The sudden appearance of Michael, the Archangel heightens the conflict in Jude. Scholars from the different camps admit Jude 9 where Michael appears in contending the devil over the body of Moses, is the most perplexing text in the entire epistle. Jesus Christ eschatological name is: Michael. The name is so significant particularly in the conflict of Moses’ resurrection to glory. Satan by all means struggled to prevent him to be resurrected and taken from his territory, for he claimed Moses belonged to his kingdom because he was a sinner.

            In epistle of Jude the great controversy does not end of the temporal life, the physical death but even extended until the day of resurrection. Whenever, Michael is referred to in the Bible, are all in the contexts of intense violence, war, death, hopelessness and resurrection and triumph. Michael is the heavenly warrior who defends victoriously for His people who will end the great controversy in grandest victory, is indeed the highlight of Jude’s eschatology.

The Significance of tabnith in the Context of Correspondence of Heavenly and Earthly Sanctuary in Exodus 25:9, 40
Authors: Abin Blasius
Published: August 2020

The picture of the heavenly sanctuary/temple is that of a model for the construction of the earthly counterpart. This understanding is conveyed mainly by the concept of תַּבְנִ֣ית, “pattern, form, or model” in Exod 25:9, 40 or σκιά, “shadow” in Heb 8:5, or ὑπόδειγμα, “copy” in Heb 9:23, 24. It reveals that the heavenly sanctuary functions as the archetype of the earthly temple. In the context of the book of Exodus, תַּבְנִ֣ית functions as the model of the sanctuary Moses was to build on the earth. Moses was probably shown the heavenly sanctuary and a “model” of what he had to build upon the earth. The תַּבְנִ֣ית thus presupposes an original reality and, at the same time, also suggests an idiomatic correspondence between the heavenly sanctuary and its earthly counterpart.

Language production and implicit statistical learning in typical development and children with acquired language disorders: an exploratory study
Authors: Mok Xue Ting Joelle , Li Goh Siew , Saddy Doug , Varley Rosemary , Zimmerer Vitor
Published: August 2020

Statistical properties of language provide important cues for language learning and may be processed by domain-general cognitive systems. We investigated the relationship between implicit statistical learning (the unconscious detection of statistical regularities in input) and language production. Twenty typically developing (TD) children and nine children with acquired language disorders (ALD) (aged 6 to 18 years) took part in a Boston Cookie Theft picture description task. Using a computerized analysis, we investigated statistical properties, such as usage frequency of words and collocation strength of word combinations. Participants also completed a non-linguistic serial reaction time (SRT) task, which tested non-verbal, implicit statistical learning in the visual-motor modality. We determined age effects, and compared language production and SRT performance between both groups. Older TD children produced more connected language, more words, less frequent function words, more rare or novel combinations, and showed better statistical learning. Children with ALD produced less connected language, more weakly collocated combinations, displayed less lexical diversity and showed poorer statistical learning. Post-hoc analyses found correlations between statistical learning and statistical properties of spoken language. Given the rarity and heterogeneity of children with ALD, group size was small and the study should be considered exploratory. However, we note that results are compatible with the view that language production draws on statistical learning and that impairment of statistical learning can be related to language disorders.

Published: August 2020

The ability to carry out instrumental activities of daily living, such as paying bills, remembering appointments, and shopping alone decreases with age, yet there are remarkable individual differences in the rate of decline among older adults. Understanding variables associated with decline in instrumental activities of daily living is critical to providing appropriate intervention to prolong independence. Prior research suggests that cognitive measures, neuroimaging, and fluid-based biomarkers predict functional decline. However, a priori selection of variables can lead to the over-valuation of certain variables and exclusion of others that may be predictive. In the present study, we used machine learning techniques to select a wide range of baseline variables that best predicted functional decline in two years in individuals from the Alzheimer’s Disease Neuroimaging Initiative dataset. The sample included 398 individuals characterized as cognitively normal or mild cognitive impairment. Support vector machine classification algorithms were used to identify the most predictive modality from five different data modality types (demographics, structural MRI, fluorodeoxyglucose-PET, neurocognitive, and genetic/fluid-based biomarkers). In addition, variable selection identified individual variables across all modalities that best predicted functional decline in a testing sample. Of the five modalities examined, neurocognitive measures demonstrated the best accuracy in predicting functional decline (accuracy = 74.2%; area under the curve = 0.77), followed by fluorodeoxyglucose-PET (accuracy = 70.8%; area under the curve = 0.66). The individual variables with the greatest discriminatory ability for predicting functional decline included partner report of language in the Everyday Cognition questionnaire, the ADAS13, and activity of the left angular gyrus using fluorodeoxyglucose-PET. These three variables collectively explained 32% of the total variance in functional decline. Taken together, the machine learning model identified novel biomarkers that may be involved in the processing, retrieval, and conceptual integration of semantic information and which predict functional decline two years after assessment. These findings may be used to explore the clinical utility of the Everyday Cognition as a non-invasive, cost and time effective tool to predict future functional decline.
Understanding professional expertise in unfamiliar face matching
Authors: White David , Towler Alice , Kemp Richard
Published: August 2020

Deciding whether or not two images are of the same unfamiliar face is an important task in many professions. These decisions are a critical part of modern identity verification processes with direct – and often profound – consequences for individual rights and the security of society. As a result, the public expect the people entrusted with these decisions to perform accurately. But do they? Here we review 29 published tests comparing face matching accuracy in professional and novice groups. Twelve of these tests show no significant differences between professional and novice groups, suggesting that merely performing the task in daily work is not sufficient to improve accuracy. However, specialist groups of Facial Examiners and Police Super- recognisers consistently outperform novices. Staff selection, mentorship, deliberate practice, motivation, feedback and training may all contribute to enhancing the performance of individuals working in these groups and future research is necessary to delineate their relative contributions.

Published: August 2020

The problems of physical education and health are very important due to the world situation. The article contains information about interests of students of higher educational institutions: we have noted the rising interest to the table tennis, as a spectacular kind of sport.

Table tennis is one of the most popular kinds of sport among students. It helps to develop following skills: accuracy, speed and reaction speed, explosive power, sense of rhythm operational thinking, the ability to concentrate attention and coordination. Table tennis has been recommended as the most perspective kind of sport, which is available for health.

The article provides an example of structure and content of physical education training lessons with students of higher educational institutions with the use of table tennis. Students of the experimental group worked at the increasing their coordination abilities at the table tennis lessons. The training was divided into three parts: preparation, the main part and the conclusion. Each part had the own differences. The preparation part took up 12-15% of the total time and was aimed to involve and warm up the big muscles.

The main part of the lesson took up 75-80% of the total time. This part was divided into three: exercises without the ball, exercises with the ball and the racket, training games. The final part of the lesson was about 10% of the total time. Exercises were aimed at relaxing: breathing, flexibility exercises, jogging, walking.

In order to improve the coordination skills it necessary to remember for methodological principles: coordination exercises should be at the beginning of the lesson, exercises should be difficult, limited of the number and duration, exercises should be at the defined time, using of the general physical exercises.

Published: August 2020

The article investigates the influence of health and recreational physical activity on terminal and instrumental values of higher education institutions students. The following research methods are used, including theoretical analysis of professional scientific and methodological resources by domestic and foreign authors, sociological, psychological and diagnostic, pedagogical research methods, methods of mathematical statistics. To determine the initial level of healthy lifestyle attitudes formation among students M. Rokych’s method of “Value Orientations” has been used. The research has been conducted on the basis of Kyiv National Linguistic University, National Pedagogical University named after M. P. Drahomanov. The study has involved 48 students (23 boys and 25 girls), who were part of the experimental (EG) and control (CG) groups (total of 24 people). The program of health-improving classes for students of higher education institutions has presupposed the use of various means of health-improving and recreational physical activities twice a week. The duration of classes was one and a half hours. Those that are most in demand among student youth were chosen as priorities. Among the young men these were strength exercises, elements of sport games and recreational games. Among the girls they included health fitness exercises. We have confirmed the feasibility and necessity of using innovative means of physical activity and forms of extracurricular activities in development of such programs that significantly increase the motivation of young people to participate in such programs. In the course of the research we have studied the hierarchy of terminal and instrumental values among young men and women who studied in higher educational institutions. The application of the developed program contributed to the students' awareness of “health” category value. Among EG students such instrumental values as education (depth of knowledge, high general culture), self- control (restraint, self-discipline) and rationalism (ability to think wisely and logically, to make thoughtful, rational decisions) have transferred to the first place. The obtained results prove that there are positive changes in the system of students’ terminal and instrumental values under the influence of health and recreational motor activity.

Published: August 2020

The study and generalization of foreign experience is a value for Ukraine, which has set itself the task of integration into the world community and can be an important source of thorough thinking and creative use of positive ideas in domestic theory and practice of physical education and sports. This article analyzes the content and features of the organization of intramural (in-school) sports in the United States. The study found that intramural sports in the United States are an integral part of the overall education program, which provides an opportunity to involve children with different levels of development of motor skills and qualities in motor activities outside of physical education lessons. Participation in intramural sports programs is voluntary. It is determined that the intramural sports program in the United States is characterized by certain features that must be taken into account for its successful implementation. It was found that, first of all, American specialists determine the direction (nature) of the sports program and possible types of physical activity, taking into account the wishes of students; it is important to properly plan and compile a quality schedule for classes in compliance with the capacity of existing sports facilities; it is obligatory to observe the rules of admission of students to classes and competitions, as well as their annual medical examination; implementation of the sports program is carried out with the use of modern information technologies; the accounting and evaluation of the program is constantly carried out; proper administration and quality arbitration are of great importance; special attention is paid to the competition procedure itself and the determination of winners; a special place is given to the financing of programs and their support and promotion.
ENERGYEFFICIENT EQUIPMENT FOR DEHYDRATION THERMOBILE MATERIALS
Authors: Sniezhkin Yu.F. , Shapar R.О.
Published: August 2020

The article substantiates the relevance of processing thermolabile materials into dried foods, as one of the alternative options for fresh fruits and vegetables. It is noted that drying, as a method of conservation, is characterized by high energy intensity and increased requirements for the quality and safety of the final product. The naturalness of the dried products and the environmental cleanliness of the process come to the fore. The criteria of quality and efficiency of the process are combined into a single task: increasing the efficiency of the drying process and creating energy-efficient equipment. The analysis of heat and mass transfer during convective drying allowed us to establish methods and ways to improve the energy efficiency of the process.

Based on a synthesis of theoretical and experimental studies, the optimal heat and humidity parameters of dehydration were determined, according to which the temperature of the material during drying does not exceed the maximum permissible value. This contributes to the preservation of valuable nutrients in the final product. Prevention of excess material temperature above the acceptable level is confirmed by the nature of the change in the numerical value of the Rebinder effect and is provided by drying in multi-stage dehydration modes, including high-temperature high-moisture method using zone drying installations of tunnel and belt type, as well as heat-pump drying installations with low heat consumption. It was emphasized that the drying of thermolabile materials is carried out in an environment of pure hot air without the use of inert and chemically synthesized substances. Non-contact air heating is carried out using traditional fuels as well as secondary and renewable energy sources. It is noted that the design features of the drying equipment make it possible to distribute the intensity of the thermal effect on the material, depending on its moisture content into zones, and also automatically maintain and control these parameters for a specific type of raw material. The adopted recirculation system of the drying agent helps prevent emissions of waste coolant and reduces thermal pollution of the environment.
ROADMAP FOR BIOENERGY DEVELOPMENT IN UKRAINE UNTIL 2050
Authors: Geletukha G.G. , Zheliezna T.A. , Bashtovyi A.I.
Published: August 2020

The purpose of the work is to elaborate a concept of Roadmap for bioenergy development of Ukraine, which outlines the goals and prospects of the bioenergy sector until 2050. The proposed Roadmap is an essential document for the country for several factors. First, it determines the contribution of bioenergy to meeting Ukraine’s international commitments to reduce greenhouse gas emissions under the Paris Climate Agreement of 2015. Second, the Roadmap shows ways to achieve existing bioenergy development goals until 2035. Third, the Roadmap can be used to elaborate the National Renewable Energy Action Plan until 2030 and the Concept of state policy on energy and environment, as well as to revise the Ukraine’s current Energy Strategy with an extension until 2050. The baseline approaches of Roadmap for bioenergy development of Ukraine until 2050 are in line with the basic principles of the Ukrainian Green Deal until 2050 and additionally take into account two promising segments of the bioenergy sector such as the development of production and consumption of first- and second-generation biofuels and biomethane. The structure of consumption of biofuels by their types and by types of produced energy carriers is proposed. It is estimated that in 2050, about half of the total biofuels consumption will come from solid biofuels used for heat production. The rest in comparable proportions will be split between solid biofuels for power production, biogas, biomethane, and liquid biofuels. Further, the Roadmap needs to be detailed, refined and expanded to the level of the Strategy for bioenergy development in Ukraine until 2050.

Published: August 2020

This article is based on my personal reminiscences about the early days of computer chess tournaments, describing not only how different the technology was, but also that progress was steady and continues today in the broader field of Artificial Intelligence. The author was a participant in the 1st ACM computer chess championship (1970) and continued to compete well into the 1980s. Speaking for myself, I learned how to play chess in Junior High School (actually King Charles 1 Grammar School in Kidderminster, UK), but now only remember losing in a simultaneous game with C.H.O’D. Alexander (the UK Chess Champion) in 1950. In High School (Preston Grammar School) I played for the school’s chess team, who were undefeated in the 1954–55 school year. Naturally I played for the University of Nottingham (where I was studying Mathematics), and later for the Bedfordshire County team, before leaving to join Boeing, Seattle, in 1962. That said, I don’t think I was ever better than a Class A player. Basically, I have played chess all my life, and it has helped develop my problem-solving skills.

Published: August 2020

Official statistics of the counterfeit medicines circulation significantly reduces the level of patient confidence not only to pharmacy specialists, but also to the healthcare system and even other government institutions. All stakeholders, from academics to politicians, point to the significant implications of this situation for the healthcare system. The relevance and complexity of the problems of combating the falsification of medicines requires an expert assessment of pharmacy specialists.The aim of the work is to evaluate the effectiveness of the anti-counterfeiting of medicines using a questionnaire of specialists of the State Service of Ukraine on Medicines and Drug Control and its territorial bodies.The object of the research was scientific publications, as well as the study of the opinions of specialists of the State Service of Ukraine on Medicines and Drug Control and its territorial bodies on the problems of anti-counterfeiting of medicines. The study was conducted using questionnaire survey methods, systematization and generalization.According to the results of the survey, respondents rated the work of the State Service of Ukraine and its territorial bodies on the prevention of the sale of counterfeit drugs as effective, but there are some problems – 67.16% and 76.12%; in general, as effective – 31.34% and 20.90% respectively. An assessment of the directions of inspection of pharmacies has showed that the majority of respondents to the first place belonged – the cancellation of a note of  warning about planned inspection (86.57%), to the second and third – simplification of the inspection procedure in the presence of consumer complaints (without additional approvals), 64.18% and the introduction of the right to conduct «test purchases» of medicines by inspectors (56.72%), respectively. Effective methods that are appropriate to use to identify counterfeit drugs included: scanning 2-d barcodes using special equipment and software – 79.10%, a detailed study of supporting documents – 53.73%, a careful visual inspection of packages – 47,76%.Based on the results of the expert evaluation, the most important tools were established that minimize the problem of counterfeit medicines circulation: a significant increase in the powers of the regulatory body (according to the FDA) – 70.15%, independent serial quality control of imported and manufactured drugs and APIs – 64.18%, strengthening responsibility for admission to the pharmaceutical market of drugs with unproven effectiveness – 59.70%.According to the results of an expert evaluation of the pharmacy specialists, the most important priorities of state policy were established, that allows to increase the effectiveness of the medicines’ anti-counterfeiting, namely improving the system of state quality control and strengthening the responsibility for falsification of medicines.

Kelelahan adalah suatu keadaan yang relatif, tetapi semuanya berakibat kepada pengurangan kapasitas kerja dan ketahanan tubuh. Kelelahan otot secara fisik antara lain akibat zat-zat sisa metabolisme seperti asam laktat, CO2 dan kontraksi otot yang kuat dan lama. Hambatan aliran darah yang menuju ke otot yang sedang berkontraksi mengakibatkan kelelahan otot yang hampir sempurna selama satu menit atau lebih karena kehilangan makanan terutama kehilangan oksigen.Penelitian ini bertujuan untuk mengetahui pengaruh efflurage terhadap penurunan nyeri gastrocnemius pada pemain futsal club futsal DPC Bontocani. Jenis penelitian ini bersifat pra eksperimen dengan rancangan penelitian one group pre tes – post tes desain.Hasil penelitian menunjukkan bahwa pemberian efflurage dapat menghasilkan penurunan nyeri dari 4,540 pada pre test menjadi 3,040 pada post tets pada skala VAS, dengan rata-rata penurunan nyeri sebesar 1,500. Kemudian hasil Uji Pairet t-sample menunjukkan bahwa pemberian efflurage dapat memberikan pengaruh yang bermakna terhadap penurunan nyeri gastrocnemius dengan nilai p (0,000) < 0,05.Dengan demilian dapat disimpulkan bahwa pemberian efflurage dapat memberikan pengaruh yang bermakna terhadap penurunan nyeri gastrocnemius pada pemain futsal club futsal DPC Bontocani.Kata Kunci : Efflurage, Nyeri Gastrocnemius

Efecto del tono de voz y de la percepción del rostro en la formación de impresiones sobre los hablantes mediáticos
Authors: Soto Sanfiel María Teresa
Published: August 2020

Se observó el efecto de la frecuencia fundamental de las voces (el tono) y de la percepción del rostro en las impresiones sobre hablantes mediáticos. Se pretendía determinar si existía relación entre la información visual y una característica eminentemente acústica: el tono. 320 sujetos fueron sometidos a una de dos condiciones: sonora (percibían sólo las voces) o audiovisual (veían las caras). Luego, respondían mediante escalas del diferencial, a la pregunta: ¿El locutor le pareció? Los resultados muestran que el tono influye en las impresiones, que la percepción del rostro evidencia las diferencias en el enjuiciamiento de las voces agudas, medias o graves, y que la credibilidad dirige las evaluaciones.
Latinoamericanos en el sur de Brasil: recepción mediática y ciudadanía de las migraciones transnacionales
Authors: Cogo Denise , Dutra Brignol Liliane
Published: August 2020

En el presente artículo abordamos los procesos de interacción mediática de las migraciones contemporáneas de latinoamericanos en el contexto de la ciudad de Porto Alegre, capital del estado de Rio Grande do Sul, Brasil. Desde la perspectiva de los estudios de recepción latinoamericanos y a través del empleo de historias de vida y de grupos de discusión, analizamos cómo esas interacciones se constituyen en lugares de (re)invención de apropiaciones y usos mediáticos de migrantes que (re)configuran sus experiencias migratorias en ámbito local y conforman procesos identitarios específicos relacionados con la "latinoamericanidad".
Infancia y maternidad después de la Revolución: sus imágenes y representaciones a través de un diario tapatío (1917–1943)
Authors: Fregoso Centeno Anayanci
Published: August 2020

El presente trabajo analiza las imágenes, representaciones y concepciones de maternidad e infancia que circularon en El Informador, cuerpo discursivo que da cuenta de la emergencia de construcciones sociales. La hipótesis que motivó la investigación fue que las construcciones de maternidad e infancia jugaron un papel central dentro del proceso revolucionario de reconstrucción del nuevo Estado mexicano. Asimismo, el interés se centra en reconstruir la experiencia local en relación con el debate nacional en torno al orden discursivo de género que establecía ciertas pautas de comportamiento para mujeres y sus hijos, y sobre el cual el diario tapatío da pistas para su interpretación.
