Authors: Jawad F. , Karpenko H. , Zagorodnyuk A.V.
Published: February 2020

Let $X$ be a weighted direct sum of infinity many copies of complex spaces $\ell_1\bigoplus \ell_1.$ We consider an algebra consisting of polynomials on $X$ which are supersymmetric on each term $\ell_1\bigoplus \ell_1.$ Point evaluation functionals on such algebra gives us a relation of equivalence `$\sim$' on $X.$ We investigate the quotient set $X/\sim$ and show that under some conditions, it has a real topological algebra structure.
A note on compact-like semitopological groups
Authors: Ravsky A.
Published: February 2020

We present a few results related to separation axioms and automatic continuity of operations in compact-like semitopological groups. In particular, is provided a semiregular semitopological group $G$ which is not $T_3$. We show that each weakly semiregular compact semitopological group is a topological group. On the other hand, constructed examples of quasiregular $T_1$ compact and $T_2$ sequentially compact quasitopological groups, which are not paratopological groups. Also we prove that a semitopological group $(G,\tau)$ is a topological group provided there exists a Hausdorff topology $\sigma\supset\tau$ on $G$ such that $(G,\sigma)$ is a precompact topological group and $(G,\tau)$ is weakly semiregular or $(G,\sigma)$ is a feebly compact paratopological group and $(G,\tau)$ is $T_3$.
Barreras para acceder a los servicios de rehabilitación de la baja visión: Una revisión de tema
Authors: Oviedo María Del Pilar
Published: February 2020

Objetivo:  Analizar las barreras reportadas en la literatura para el acceso a los servicios de rehabilitación de la baja visión.Materiales y métodos: Se realizó una revisión narrativa a partir de literatura científica publicada en el período 2008 a 2019 y vinculada en las bases de datos Pubmed, Scielo, Ebsco y Science Direct.Resultados:  Las barreras reportadas por los prestadores de servicios de salud están relacionadas con la falta de conocimientos en baja visión y el escaso número de profesionales que se dedican a la atención así como la invisibilizacion de la misma en los planes de atención ocular.  Las barreras manifestadas por las personas están relacionadas con la falta de información y conocimiento sobre los servicios de baja visión, dificultades para el desplazamiento/transporte y el temor a los estereotipos.Conclusiones: Las barreras para acceder a los servicios de rehabilitación son complejas, y algunas pueden abordarse más fácilmente que otras. Un aspecto clave para disminuir las barreras puede ser la mejora de la formación del recurso humano y la generación de canales de comunicación entre los profesionales y las personas.  El estigma asociado a la discapacidad visual es un elemento que parece ser crucial y que debe abordarse.
Genetic Networks Underlying Natural Variation in Basal and Induced Activity Levels inDrosophila melanogaster
Authors: Watanabe Louis P , Gordon Cameron , Momeni Mina Y , Riddle Nicole C
Published: February 2020

Exercise is recommended by health professionals across the globe as part of a healthy lifestyle to prevent and/or treat the consequences of obesity. While overall, the health benefits of exercise and an active lifestyle are well understood, very little is known about how genetics impacts an individual’s inclination for and response to exercise. To address this knowledge gap, we investigated the genetic architecture underlying natural variation in activity levels in the model system Drosophila melanogaster. Activity levels were assayed in the Drosophila Genetics Reference Panel fly strains at baseline and in response to a gentle exercise treatment using the Rotational Exercise Quantification System. We found significant, sex-dependent variation in both activity measures and identified over 100 genes that contribute to basal and induced exercise activity levels. This gene set was enriched for genes with functions in the central nervous system and in neuromuscular junctions and included several candidate genes with known activity phenotypes such as flightlessness or uncoordinated movement. Interestingly, there were also several chromatin proteins among the candidate genes, two of which were validated and shown to impact activity levels. Thus, the study described here reveals the complex genetic architecture controlling basal and exercise-induced activity levels in D. melanogaster and provides a resource for exercise biologists.

Authors: Jayedi Aman
Published: February 2020

Despite the fact that windows have a vast scale sway on thermal environment bearing in mind window dimensions and alignments, more often than not, for naturally ventilated architectural design studios in Dhaka it ends up being troublesome to give the agreeable warm condition for educating and learning within the studios due to high temperature amid summer term. As a result, electrical means are required to make non-natural condition that puts mammoth weight on the complete national energy need. This examination intends to discover a compelling window classification from accessible window setups in existing architecture studios, situated in various open and private colleges in Dhaka through simulation readings for enhancing the thermal conditions, which can be seen as agreeable by a large portion of the inhabitants, as indicated by PMV-PPD. Field examination was done to distinguish the current windows, which are utilized in architecture studios with regards to Dhaka. At that point, the case design studio was chosen and simulation instrument EnergyPlusTM was utilized for estimating the execution of the accessible window arrangements as for thermal conditions. For the simulation study at the last stage, the test points and core test points of virtual 3D-case studio were established. In light of the investigation, for architecture design studios in Dhaka, ‘segregated viewing windows’ classification was deemed as best among the chosen window classes.

Purpose. To make a comparative analysis and evaluate the effectiveness of physical exercises in a technical university and departmental university of the Ministry of Internal Affairs of Russia.
Material and methods. The study involved male students (1 functional group of health) of the Irkutsk National Research Technical University (Russia, n = 1380) and cadets of the East Siberian Institute of the Ministry of Internal Affairs of Russia (Russia, n = 762). Cadets studied at 1, 2 and 3 courses. The characteristics of physical preparation and the functional condition of students and cadets were analyzed.
Results. During the training period, most indicators of cadets' physical preparation significantly exceed their values ​​in students. This is due to the preliminary selection of candidates for training in educational institutions of the Ministry of Internal Affairs of Russia. It is also associated with a expressed training orientation of the process of physical preparation. The dynamics of the values of the indicators of the functional condition of the body of cadets is characterized by a high price of adaptation to physical activity. This can lead to the occurrence of pre-pathological conditions and pathological processes of the cardiovascular system.
Conclusions. The dynamics of the values of indicators of physical preparation of students and cadets cannot be the only objective criterion for the effectiveness of the system of their physical education. For its full assessment, it is necessary to analyze the parameters of the functional condition of the body, characterizing the reaction to physical activity. Cadets have a great adaptation to physical activity. In this case, it cannot be concluded that the physical training of cadets is more effective.

Purpose: A significant volume of data on the level of physical activity and health of male students presents at the literature. Scientists use the International Physical Activity Questionnaire (IPAQ) to collect data. Scientists point to the need to use objective practical tests that complement the IPAQ data. The purpose of the research is to search for objective data on the level of physical activity of undergraduate male students receiving education in Russian Federation. Material: Participants – male students (n=205, age-19-20 years). The period of research is March-April 2019. Students were divided into groups: G-1 – students (n=127) who did not have proof of their physical activity in sports and fitness, G-2 – students (n=78) who had provided confirmation. The International Physical Activity Questionnaire (IPAQ) in its extended version assessing four domains of activity, which was supplemented with original questions regarding perceived physical fitness (high, moderate, low) and favorite physical activity in sports and fitness was used in research. Students' physical fitness profile testing is performed using Functional fitness assessment tests. The collected data were analysed using SPSS20. Physical fitness test results were compared by using Mann-Whitney U–test. Results: The IPAQ data indicate a significant (P<0.001) advantage of students (G-2) in total physical activity. Students (G-1) have a significant (P<0.01) advantage in the volume of physical activity at work. The volume of physical activity in sports and fitness is significantly higher (P<0.001) for students (G-2). Functional fitness tests showed a insufficient level of physical fitness of students (G-1 and G-2). The results indicate a significant (P<0.01) advantage of students (G-2) in physical profile. Conclusions: Russian male students have more total physical activity than male students from African countries, Turkey, Iran, and Ukraine, but have a significantly low total physical activity level than students from some European countries. The total physical activity volume of Russian university male students is slightly less than the recommended by experts (6000 minutes per week or more). The volume of validated physical activity in sports and fitness of Russian students is about 39 minutes per day. The level of physical fitness of Russian male students does not fully comply with the Functional fitness assessment tests targets. A large proportion of sports and fitness physical activity has a significant impact on the results of functional fitness tests. Data on favorite types of physical activity of Russian male students show a preference for young men to physically dominate their peers. Health preservation and health care are not the main aim of students.
Personality differences between academic team sport players and physical education undergraduate students
Authors: Rogowska Aleksandra M.
Published: February 2020

Background and Study Aim: Although personality research in psychology of sport has a long history, a little is known about the personality of the team sport players among university students. The aim of this study is to investigate differences in personality traits between Team Sport Players (TSP), Physical Education Students (PES) and Other Faculties Students (OFS). Material and Methods: Participants in the cross-sectional study were 441 university students aged between 18 and 34 years old (M = 22.09, SD = 2.19), including 60.09% of men, at a large university in the south of Poland. The NEO-FFI questionnaire was used to assess Big-Five personality traits.
Results: One-way ANOVA revealed that TSP sample scored significantly lower in neuroticism, openness and agreeableness than both PES and OFS groups. TSP also demonstrated higher scores in extraversion, in comparison to PES. The PES and OFS did not differ one another in personality traits. Conscientiousness was at the same level in all three groups.
Conclusions: Increasing achievement motivation and compliance with norms may heighten conscientiousness among undergraduates. The information about personality should be used by the coach to team conflict reduction, to make an appropriate selection decision and to develop individual development plans for particular team members.

Memorability of Enhanced Informational Graphics
Authors: Peña Alyssa , Ragan Eric , Harrison Lane
Published: February 2020

Design enhancements are often added to charts, signage, and infographics to help garner attention or communicate a message. Though it is argued that they may also detract user’s focus on the underlying information, prior studies have contributed evidence that visual design enhancements and even simple decorations can improve memory of visual displays. However, there is limited empirical knowledge about how the type of aesthetic enhancements infuences memory, and what informational and data elements are remembered from a visualization. We conducted a user study testing chart types (line, pie, and bar), the presence of color, and whether added enhancements were contextually related to the data topic presented in each chart. We found that enhancements relevant to the data helped in the recall of title and thematic elements, but enhancements did not signifcantly affect recall of specifc data values. This suggests that using relevant enhancements can have a positive effect on memorability of some chart content, but only if the design styles are chosen well to match the information topic. Recall of chart topics for unrelated embellishments was worse than plain, un-enhanced charts, which suggests that visual enhancement can distract or interfere with memorability if the viewer does not understand a meaningful connection between informational topic and design modifcations.
Analysis of Signage using Eye-Tracking Technology
Authors: Tang Ming
Published: February 2020

Signs, in all their forms and manifestations, provide visual communication for wayfinding, commerce, and public dialogue and expression. Yet, how effectively a sign communicates and ultimately elicits a desired reaction begins with how well it attracts the visual attention of prospective viewers. This is especially the case for complex visual environments, both outside and inside of buildings. This paper presents the results of an exploratory research design to assess the use of eye-tracking (ET) technology to explore how placement and context affect the capture of visual attention. Specifically, this research explores the use of ET hardware and software in real-world contexts to analyze how visual attention is impacted by location and proximity to geometric edges, as well as elements of contrast, intensity against context, and facial features. Researchers also used data visualization and interpretation tools in augmented reality environments to anticipate human responses to alternative placement and design. Results show that ET methods, supported by the screen-based and wearable eye-tracking technologies, can provide results that are consistent with previous research of signage performance using static images in terms of cognitive load and legibility, and ET technologies offer an advanced dynamic tool for the design and placement of signage.
Centrifuge modelling of lateral cyclic behaviour of a tetrapod piled jacket in soft clay
Authors: Zhu Bin , Ying Panpan , Zhu Zhoujie , Lin Weian , Kong Deqiong
Published: February 2020

This paper describes a series of centrifuge tests on the cyclic lateral behaviour of a tetrapod piled jacket foundation (TPJ) in Malaysian kaolin clay. The dimensions and axial and bending stiffness of the model foundation were determined in accordance with a prototype TPJ foundation built in the Guishan offshore wind farm in Guangdong Province of China. Both one- and two-way cyclic loadings with differing load magnitudes were applied. The rotational, lateral and vertical displacements of the TPJ and the corner piles, the distribution of internal forces along piles and the lateral pile–soil interactions were scrutinised. It was shown that settlement of the model foundation is dominant during both one- and two-way loading, and even the upwind piles that are expected to be pulled up exhibit considerable downward displacement except for the very first few cycles of loading. In addition, a two-way loading that is applied after one-way loading could generate considerable reversal accumulative displacements, both rotationally and laterally, on the TPJ foundation, provided that the load magnitudes are comparable. The reduction in lateral pile–soil resistance with the number of loading cycles is quantified by means of a degradation factor, which appears to be significantly higher than that in sand.

Bagasse-Based Desiccant Wheel Dehumidifier
Authors: Ramchurreetoo H. , Rajkumarsingh B.
Published: February 2020

Green desiccants are obtained from natural waste products like bagasse. They are fully biodegradable and cause no harm to the environment compared to chemical desiccants. A bagasse-based desiccant wheel dehumidifier that uses a green desiccant like sugarcane bagasse to remove humidity from air has been implemented and tested. Sugarcane bagasse was chosen as the main desiccant since it not only shows high adsorption properties but is also abundant in Mauritius and is much cheaper compared to other desiccants. The prototype was implemented and tested under various input parameters. A mathematical model was constructed to show how the dehumidification rate varies with airflow, desiccant wheel speed and bagasse thickness. It was found that dehumidification rate increases with an increase of the previously mentioned parameters. Another finding showed that as dehumidification rate increases, a higher regeneration rate for the desiccant is required. At maximum operating conditions, the dehumidifier has a Coefficient of Performance of 0.0118 and a Moisture Removal Capacity of 2.06 g/min. It could also be deduced that at lower temperature, the prototype has a better efficiency. A controller was implemented and incorporated in the dehumidifier which responded well to different inlet air relative humidity and temperature.

Advances in additive manufacturing technology present new design opportunities for metal parts that would otherwise be infeasible with subtractive manufacturing technologies. Clifford Machines & Technology (Pty) Ltd is an international producer of large mesh welding machines. The research was conducted with the aim of investigating the advantages that can be provided through the redesign of the mesh welding electrodes, for production using additive manufacturing. Simulation studies were applied in order to evaluate the performance of the redesigned electrodes and the results were compared to the existing electrodes. The results show that the electrodes designed for additive manufacturing achieved mass reductions of up to 58.2%. The electrodes were also able to support increases of current density by up to 98%, while operating at a lower temperature than the original electrodes. The study has identified the high initial cost of production and increased power consumption to be the disadvantages of additively manufactured electrodes.
A Parametric Design and Optimization Approach to Enhance the Fatigue Life of a Male Pyramid Socket Adapter
Authors: le Roux P.A. , Laubscher R.F.
Published: February 2020

This research paper presents a parametric design approach to optimize a male pyramid socket adapter as used on a transtibial prosthetic limb for enhanced fatigue life. These adapters are prone to premature failure when used by individuals partaking in athletic sports. A parametric design and optimization approach is presented and applied. A current design was assessed for structural integrity by finite element analysis in combination with the load criteria as recommended by the ISO 10328:2016 code of practice. Highly-stressed regions where identified and improved using a parametric design approach to reduce the maximum 1st Principal stress while adhering to the industry code of practice as applicable to pyramid socket adapter design. The optimization was validated by experimentally comparing the current design and the optimised design for an appropriate load case by low cycle fatigue testing. The socket adapters were manufactured from Ti6Al4V and subjected to a simulated resultant knee bending moment. The fatigue validation indicated a significant improvement in fatigue life for the optimized socket geometry commensurate with a reduction in stress and comparison to an appropriate SN curve for Ti6Al4V. The parametric optimization process as utilized was found to be effective and should be applicable to many different applications in a more general sense.
Slip Factor Prediction for Impellers with Straight, Back-swept Blades
Authors: von Backström T.W.
Published: February 2020

Slip factor accounts for the deviation of the flow angle from the trailing edge blade angle at the exit of radial impellers. Accurate values are required to predict impeller torque and energy input. The slip factor prediction method for back-swept radial bladed impellers is based on the so-called single relative eddy (SRE) method, which is an approximation of the classical, two-dimensional analytical solution to the inviscid flow problem. The relatively accurate prediction of the slip factors of 19 impellers found in four data sets published since its formulation, shows the reliability of the SRE method. The characteristics of straight-bladed impeller layouts are explored and incorporated into the SRE method. It turns out that the SRE method as developed for logarithmic spiral blades predicts the inviscid flow slip factor of 42 different straight bladed impeller geometries accurately, when a correction for the critical radius ratio at low blade numbers is introduced. Predicted slip factor values are also compared to new experimental data for five different impellers with straight, back-swept blades, over a range of three blade angles and three blade numbers. Agreement is excellent near the flow coefficient corresponding to the volute design angle.

Secular State and Civil Society: Search for Common Contacts
Authors: Meshcheryakova Anna F.
Published: February 2020

This article is devoted to the study of such complex phenomena as civil society and the secular state and their subsequent influence on each other. The study takes a close look at religious associations, which constitute a structural element of civil society. Freedom of action granted by the state within the framework of secularity allows them to play the role of a link between the individual, the state, and society and coordinates common and private interests, and thus contributes to strengthening relations between these entities. Thus, secularity acts as a fundamental legal value. Taking into consideration the essential features of the secular state, we trace peculiarities of the relationship of religious associations to authorities at the present stage. It is proved that their active citizenship helps the state solve many issues related to meeting diverse needs of the individual. At the same time, the study focuses on the imperfection of Russian legislation governing various aspects of secularity, specifically on the vagueness and inaccuracy of some formulations which lead to a clash of opinions and interests of people with different worldviews and groundless accusations of authorities of clerical tendencies. At the same time, clericalization is a negative factor destabilizing civil society, hindering its normal development. We express an opinion on the admissibility and even expediency of statechurch interaction, which, with strict legislative regulation, cannot be identified with the attempts to clericalize power and society. The study also defines the freedom of religion limits (freedom of conscience) in the formation of a secular state and civil society

The aim of the work is to study the criminal policy in relation to crimes committed using technologies based on artificial intelligence algorithms. The varieties of these crimes are described: phishing, the use of drones, the synthesis of fake information, attacks through automated autonomous systems and bots. Given the fact that artificial intelligence technologies are capable of self-learning and independent actions without direct human intervention and control, the key issue in the criminal policy regarding crimes committed using artificial intelligence algorithms is the question of the subject of criminal liability. The concepts existing in official documents and scientific literature are analyzed on this issue, in the development of scientific discussion, it is proposed to update the legal construction of “innocent harm”. The prospects of criminal policy in this direction are indicated in the creation of a fundamentally new variety of blanket norms: from “law as a text” to “law as a code” and its implementation by technological platforms

Published: February 2020

In this article the phenomenon of boredom is considered in a paradoxical way. On the one hand, we have before us the substance of spoiled time, that is, the content of life, which is identical with its emptiness. But human adulthood is largely determined by the ability to deal with boredom, to make it bearable. And the most important way to this is the reception of art as a symbolic production. Boredom allows you to deal with not relevant things. Thus it is in it, in the background boredom, that the art of opuses gets its most reliable support

Es evidente el constante cambio que sufre nuestro entorno, modificaciones en el clima, nuevas infraestructuras y, sobre todo el avance tecnológico, el cual contribuye al desarrollo de las ciencias, la creación de nuevos inventos y avances en los medios audiovisuales, entre otros. Estos últimos roban cada vez más atención a muchas personas, principalmente a las nuevas generaciones. Todo a nuestro alrededor evoluciona y la educación no puede quedarse atrás; el estudiante se interesa mucho más por internet, la televisión, los móviles y el cine, entre otros, dedicando menos tiempo a las labores académicas. La solución de dicho problema no está en prohibirlos sino en aprovecharlos para beneficio del proceso formativo. Frente a esta situación en el presente trabajo de investigación se examina: la existencia, estado y el uso de los recursos audiovisuales interactivos en el proceso enseñanza–aprendizaje y su relación con el rendimiento académico de los alumnos, el trabajo docente y la eficiencia de una institución educativa de la zona sur de la comunidad de Madrid. Igualmente se explora el uso real que se da de este tipo de recursos de educación y la opinión que tienen los docentes al respecto. Para ello se ha diseñado un cuestionario con tres bloques (dimensiones), validado para este fin. Los resultados muestran que se utilizan los Recursos Audiovisuales interactivos y su selección y validación, siguiendo criterios pedagógicos que influyen de manera positiva en el aprendizaje.

In the brief overview of the procedure for enacting an administrative act it is stated that in the German understanding the administrative procedure with its inherent control mode, goal orientation and role of the various institutions and bodies as well as persons involved in the intermediary role between constitutional requirements and administrative reality is not purely technical one. The authority decides ex officio about the opening of the procedure except a citizen applied for, it decides at its discretion except when it must act ex officio how to proceed. Its important principles named as informality, simplicity, expediency, speed, obligation t o cooperate and freedom of form. Special importance is attributed to the principle of officiality of the investigation of a given case. The relevance of circumstances arises from the relevant legal norms and – i case of – discretionary decisions. The extent of the proof and the burden of proof are also important for the scope of the official investigation principle. Authorities are obliged to grant the citizen a right to be heard in the administrative procedure and to influence the course and outcome of the procedure. It carries direct and indirect external impact, revealing the basic understanding of relations between the state and the individual derived from the constitution. Equal treatment of all citizens and material substantivity proves the rule of law and prohibits the abuse of power at the expense of the citizen.

Published: February 2020

Background: Currently, the car, water, railway, air and pipe transports are used for cargo and goods transportation. Each kind of cargo transport has its own specific competitive advantages that provide its most effective application at various stages of logistics chain. The economic efficiency of cargo transportation influences the overall economic efficiency, in particular, the gross domestic product. The quality of economic growth as applied to transport branch and its input to the national economy is relevant, since with the current organisation of different transport modes interaction, there are still high transaction costs.
Aim: Study of influence of various modes of transport, including maglev transport, on the economy and economic growth.
Methods: Theoretical and empirical. The paper considers the influence of various modes of transport, that operate in the cargo transport sphere, on the countrys economy. The comparison of existing modes of transport with the maglev transport from the point of view of desired effects is made.
Results: The maglev transport possesses new properties and advantages, which makes it possible to view is as viable and able to provide a qualitative economic growth and resource-based economy if realised.
Conclusion: The most efficient use of resources, the consumption of which should at least not increase and at most decrease, is achieved with the introduction of maglev transport into the transport system, as its economic properties already now excel those of the majority of other types of transport. It is obvious, as to the experts, that in transition to resource-based economy the maglev transport will be major transport for both cargo and passenger transit.
On Assessment of Influence of Innovation Activities Results on the National Economy

Published: February 2020

Background: Development of Science in Russia is currently in urgent need of a thorough support from the state. Fundamental researches create ground for detalisation of innovative ideas and bring them closer through applied research to their developments and implementation. Ensuring sustainability of the countrys economy is possible only through contributing resources to researches of immediate relevance.
Under existing conditions, special relevance is acquired by development of tools for assessment of additional effects of financing innovative development.
Aim: The purpose of this study is to assess the impact on the national economy of the costs on innovative development of companies.
Methods: Search for and analysis of:

options of assessment of available information about results of scientific researches (both patented and those that are not officially registered as intellectual property);
ways of deriving economic benefit from owning scientific researches results with absence of opportunity for their introduction into a companys activity or for selling.

To assess the influence of expenses for innovative development on the national economy, the index of innovation support for the national economy (ISNE) is suggested to be used.
Results: The algorithm for calculation of ISNE is presented. It is suggested to consider relevant for calculation those expenses of the companies, that work on development independently or with the help of national knowledge generation sector and higher education. These expenses are for:

salaries, considering premium;
procurement of national equipment and materials;
paying for work carried out and services rendered by contracted companies.

All other expenses at this stage are suggested to be deemed as irrelevant.
The factor can be calculated for each company-resident, irrespective of type of activity and field of scientific researches for ID purposes.
Conclusion: For companies that investing considerably in scientific and technical, innovative development, the increase of ISNE can be an additional incentive (with governmental support), will help in drawing attention to existing potential of the Russian science, save and multiply number of scientific schools, maintain high quality of scientific development and their effectiveness.
