Engaging Students in Science Using Project Olympiads: A case study in Bosnia and Herzegovina
Authors: Dogan Senol , Spahiu Emrulla
Published: March 2021

Making science enjoyable inspires students to learn more. Out-of-class activities such as science fairs and Olympiads, serve as reasonable informal learning environments that demand attention. The association  of students’ involvement in these activities with increased student interest in science followed by the selection of  science-related careers, should motivate all in-charge stakeholders. In this work, we analysed the outcomes of the Bosnia Science Olympiad (BSO) as the first national Science Olympiad in Bosnia and Herzegovina (BiH), aiming the improvement of science education and bringing different ethnic groups under the umbrella of science, in a post-conflict area. The two-day endeavour held in Sarajevo includes competition in  four sciencerelated categories (Environment, Engineering, Have an Idea, Web Design) and social activities. In this work, the comprehensive data, including participants’ gender, their ethnic background, cities, schools, and supervisors, over five years, was analysed. The number of participating high-school students increased from 78 to 143, of supervisors from 21 to 95, and of schools from 7 to 15, reaching a wide demographic acceptance to cover all ethnic regions in BiH. The relationship between gender and the selection of a category, shows bias of male participants towards Web Design (21%) and Engineering (40%), and of female students towards “Have an Idea” (40%) and Environment (44%) categories. The contribution of BSO choosing a science career, getting socialized    without prejudices, and the improvement of students’ self-confidence, were as well addressed. Our work demonstrates a model work to successfully promote science in post-conflict settings. 
Achieving Sustainable Development Goal 1 in Ogun State, Nigeria : Lessons from the Millennium Development Goals Poverty Reduction Strategy
Authors: Anuoluwapo Durokifa , Uwizeyimana Dominique
Published: March 2021

There is no gainsaying the fact that one of the objectives of the Sustainable Development Goals is to end poverty in all its form by 2030. However, the continuous increase in poverty level has generated a lot of debates among policymakers and scholars while government keeps formulating policies to avert the situation. Thus, with SDGs in view, the study took into cognizance the MDGs before it and what hindered it from the full actualisation of its goal, specifically MD Goal 1a “eradicate extreme poverty”. Using quantitative data, the study examined the implementation of MDGs and pinpointed the factors that affected the implementation of the MDG poverty reduction strategy. These factors include corruption, lack of awareness, politics of poverty, non-poor targeted, etc. On this basis, the paper suggests that, if Ogun State will achieve SDG1 by 2030, factors such as good leadership, identification of the poor, awareness and infrastructural opportunities will need to be addressed.
Evaluation of the Lipid-binding Properties of Recombinant Dystrophin Spectrin-like Repeat Domains R1-3
Authors: Cooper-Olson Grace , Rodino-Klapac Louise R. , Potter Rachael A.
Published: March 2021

Recombinant micro-dystrophin genes are designed to treat Duchenne muscular dystrophy (DMD) by retaining dystrophin domains believed to play key functional roles while fitting the packaging capacity of adeno-associated virus vectors. Domains R1-3 are important for muscle force generation and for association with the sarcolemma, but the nature of this interaction is not fully understood. We measured lipid-binding affinity of 3 peptides containing different spectrin-like repeat modules (R1-3; R1-2; and R1, 2, 22). Lipid-binding affinity was highest with R1-3, suggesting that the complete R1-R3 region could be beneficial and should be considered for inclusion in micro-dystrophin constructs.
Оscillations of closed conical shells with complex rotation
Authors: Lizunov Petro , Kriksunov Eduard , Fesan Oleksandr
Published: March 2021

The paper consider a system of two closed conical shells connected by a central rigid insert rotating in opposite directions in a central force field with a constant angular velocity around the axis of symmetry of the system. The shell element is subjected to a load consisting of gravitational and inertial forces, but at large values of the angular velocity of the system, the gravitational loads can be neglected. The gyroscopic interaction between the rotational portable motion of the system and the relative elastic oscillations of the elements is a source of excitation of precession oscillations, which may be resonant or unstable. Occurring when changing the axis of orientation of the system gyroscopic moment causes the appearance of alternating stresses, which significantly affect the strength and reliability of the shells. Such problems arise in construction engineering, mechanical engineering, aircraft construction, space engineering and other sectors of the economy. The main load acting on the elements of such systems are significant centrifugal forces of inertia, which significantly affect the strength characteristics of structures. Taking into account the periodicity of the right-hand side and the coefficients of the system of resolving equations, with the help of the projection method it is possible to reduce the resolving equations to the system of ordinary differential equations, which approximately replaces the original one. The solution of the obtained system of equations makes it possible to determine the forms of oscillations and forces in a composite conical shell at various parameters of the shell and the ratios of the velocities of the shell's own rotation and the rotation of its center of mass.
Сomparative analysis of the methods of strengthening of masonry, metal structures, reinforced concrete, such as traditional methods and the alternative methods of strengthening by FRP-materials
Authors: Rudnieva Iryna
Published: March 2021

Built mostly centuries ago, heritage buildings as well the more contemporary buildings of the last century, which have lost the bearing capacity often need restoration and strengthening, especially in seismic regions and in regions with shrinkage phenomena (subsidence region). The need of strengthening of the building constructions during exploitation appears mostly because of their premature wear as a result of technological influences and weathering, various damage and various other factors.
Traditional methods of strengthening are effective, but in some cases not appropriate or not applicable  for use. An example is the increase of the load-bearing structures of historical buildings, preserving the external appearance of which is the determining factor. In this case, the use of the discussed alternative methods can be justified alternative.
Knowledge of the causes of defects and damage of structures allows to choose the best option of repairing or strengthening.
The aim of the research is the evaluation of the structural performance of composite fibre-reinforced elements in the wider sector of the conservation of historical, architectonic and environmental heritage, as well the more contemporary buildings of the last century, which have lost of the bearing capacity focusing reliability indexes and the appearance of the structure.
In the article was described and analyzed the existing traditional methods and the alternative methods of strengthening by FRP-materials (composite materials) such building structures as masonry, metal structures, reinforced concrete, and the computation in software ABAQUS. These procedures of strengthening building structures by FRP-materials  in Ukraine are not widely used due to the lack of a regulatory framework that would regulate their use, as well because these materials are relatively expensive compared to the traditional ones.
The article analyzed the existing methods of computation and design of the strengthening using FRP-materials, and the computation in software ABAQUS was performed with conclusions and recommendations based on results of the computation.
The aim of the work was to review the technology and analyze the advantages and disadvantages of each of the strengthen methods that should be used when choosing effective solutions for strengthening building structures. In conclusion, the need for further study and researches was confirmed.
Modified method of direct in problems of thermal conductivity of annular plates
Authors: Sovych Yuliia
Published: March 2021

In this paper, to solve the initial boundary value problem of thermal conductivity using a numerical-analytical method - a modified method of lines is proposed. The initial equations of thermal conductivity defined in the cylindrical coordinate system are considered in the spatial formulation, which greatly complicates them. As an object on which they are defined, an annular plate is considered, the overall dimensions of which are commensurate. In the problems of calculating of thermal effects in load-bearing elements the first step is to determine the temperature fields, especially if the overall dimensions of the structures are proportional. Such elements include non-thin annular plates. The boundary conditions are considered in a general form too - these are the conditions for convective heat transfer, which using the passage to the limit, turn into boundary conditions of the first and second types. The application of the modified method of lines to reduce the dimensionality of the initial system of equations of nonstationary thermal conductivity used to determine the temperature fields of the load-bearing elements is shown in this paper.
The application of the modified method of lines involves solving these initial boundary value problems in two stages. At the first stage, the dimensionality of the initial equations with respect to variable z is reduced. The Bubnov-Galerkin-Petrov projection method is used to reduce the dimensionality. The so-called functions-"caps" are accepted as basic functions, which are related to the lines plotted on the definition domain of the problem. The projection method is also used to reduce the dimension of the initial and boundary conditions, that allows to formulate a reduced initial-limit problem, which is convenient to solve using the numerical finite-difference method, using explicit or implicit difference schemes. The most successful form of writing the original equations was found, which ensures ease of application of dimensionality reduction of the initial system of equations using a modified method of lines. The calculation took into account the impact of the environment. Reduced equations, boundary and initial conditions are obtained. As a result, the reduced problem has a form convenient to its solution by modern numerical methods.

As a result of the analytical research and result of the previous stages of study it was found the significant contamination of the soil layer by the heavy metals (HMs) within the Landfill area No 5 for the municipal solid waste (MSW) disposal and the surrounding areas. It was revealed also the negative its effect on the contents of these pollutants in the soil of adjacent buffer zone, which is under the influence of north-eastern, northern, and north-western parts of the Landfill. This is a result of 34 years of the operation of the MSW disposal facility, when there were operating troubles. That caused by the breach of operating procedures of the covering the garbage storages by the isolating layers of dirt, intermittent work of the leachate treatment system, capacity exceeded, etc. Therefore, the soils within the Landfill’s boundaries and also in the buffer its zone have been contaminated by the different toxic substances, in particular by the HMs. So, soil deposits of the Landfill have got the maximum exceed of background contents for cooper, lead, nickel, and tin by from several to ten times, at the same time, beyond its contour – by 2–3 times. The negative changes of physical-chemical properties of soils of the humus horizon is revealed by the comparison with the proper indications for the soil samples collected in the sites adjacent to the Landfill and directly on its territory. The buffer coefficient of soil of this horizon (Cb) is twice as lower for the technogenic polluted soils within the MSW disposal facility than for the background sites for their is equal to the value of Cb=55. The contents of mobile forms for the HMs in the soil formations of the Landfill No 5 in the comparison with the background values increase 2 times for cooper and zinc, as well 8 times for lead. It is the content of the mobile forms that affects the migration of the HMs in the trophic chain “soil – solution – biota”.

Published: March 2021

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age that is characterized by reproductive and metabolic disorders. Mental issues, hypothalamic-pituitary dysfunction, ovarian dysfunction, mitochondrial dysfunction, obesity, and vitamin D deficiency account for infertility in PCOS. This paper reviews recent studies on pathogenesis and treatment approaches to this disease. Recognized therapeutic modalities for PCOS are addressed, i.e., rational diet, combined hormonal contraceptives, ovulation induction using clomiphene citrate and/or metformin, ovarian drilling, assisted reproductive technology, and alternative approaches (e.g., herbal therapy, traditional Chinese medicine, vitamin D, coenzyme Q, salubrinal, and the combination of simvastatin and metformin). Inositols are a promising therapeutic modality that improves menstrual and reproductive function (presumably via their impact on carbonic and lipid metabolism) and the quality of oocytes and embryos.

On the Necessity of Referral to t he Category "Randomity" In the Process of Moral Assessment of Individual's Acts
Authors:   Associate Professor of the Department of History, Philosophy and Social Communications, Omsk State Technica l University, Omsk, Russia, Makuhin Petr
Published: March 2021

In the article, firstly through the analysis of the history of ethical teachings, the basic requirements for the procedure of moral assessment, for its subject (the legitimacy of this assessment) and the object (taking into account the consequences of the act, their motives, as well as the ratio of the goal and the means used to achieve it) are identified. Consideration of a particular deed taking into account all these aspects, it would seem, allows us to make its moral assessment objective, impartial, fair. However, secondly (and most importantly!), we substantiate the thesis that if this consideration is not supplemented with the category of randomity (moreover, interpreted as aclinamen), then the resulting assessment will itself be morally problematic, giving rise to moral complacency and depriving us the opportunity to help a morally stumbled person.

Published: March 2021

The APPsyCI, a Portuguese research center, decided to incorporate, in all its areas of activity, a research line within Open Science articulated with information literacy (IL). The Open Science assumptions were implemented through several actions: repository management, teacher and researcher training, support for choosing the journals where to publish, dissemination, and promotion of scientific knowledge within FAIR principles. The social and academic impact of the research line provides some light on the national landscape for research innovation and broadens horizons and sheds when combining IL with Open Science. Thus, the creation of this research line within the research center shows that the association of Open Science with IL can be considered as the path and object of applied research.

Published: March 2021

The purpose of this study is to describe the implementation of entrepreneurial leadership during the Covid-19 pandemic at Karitas Catholic High School in Tomohon City, the supporting and inhibiting factors as well as the solutions for handling them. This research used a descriptive qualitative approach. The research subjects were five people consisting of a school principal and four vice principals. The data were collected from interviews, observation, and documentation studies. The data were analyzed by an interactive model. The findings indicate that entrepreneurial leadership was implemented through the principal role as an explorer, a miner, an accelerator, and an integrator. The supporting factors are teachers’ IT skills, government allowances, parents’ support and proactivity, online learning facilities, and entrepreneurial instincts of teachers and students. The inhibiting factors are the late payment of tuition fees, the uncertainty of parents' income, the late disbursement of the government's school operational assistance (BOS) funds and the foundation's compulsory funds, the complexity of the foundation's centralized system, and the lack of online learning facilities. The efforts to overcome the inhibiting factors are coordination with parents, overcoming arrears, recording the number of students without online learning facilities, and conducting offline learning for them. The results suggest continuing to implement entrepreneurial leadership more openly and creatively, increase the supporting factors, and minimize the inhibiting factors with various efforts.

The non-classical boundary problem of the mathematical physics for the two-dimensional Poisson equation is considered. As the area, in which the solution is sought, the area, made up of different circular segments, folded into a multi-sheet plate of a book structure, is taken. All sheets are different from each other, both in their physical properties and in geometric dimensions, and are interconnected by a chord common to all sheets. The problem statement is given and its exact solution is obtained.The solution to the problem is considered in bipolar coordinate systems, each of which is associated with one of the segments. In this case, all coordinate systems have a common parameter - the length of the rectilinear segment boundary. As a method for solving the problem, the classical method of separation of variables is used – the Fourier method. Although the Dirichlet problem is considered as a basic one, however, the proposed method can be applied in the case when conditions of other types are given on the arcs of separate circles: Neumann or the third main problem.The statement of the considered problem differs from the classical one in that the conjugation conditions of fields on the line of connection of segments are added to the traditional boundary conditions. These conditions represent the equality of the values of the functions and the equality to zero of the sum of linear combinations of their normal derivatives. The solution is constructed (selected) in such a way that the first of the field conjugation conditions is fulfilled automatically for any choice of unknown functions. The boundary conditions on the segments and the second conjugation condition make it possible to determine all the unknown functions of the problem. To apply the Fourier method, it is necessary that all boundary functions are equal to zero at the corner points of the segments. If this condition is violated, a modification of the method that allows one to obtain an exact solution in this case is proposed. As an application, such problems are considered: a) on the torsion of a composite rod, the cross-section of which is two different segments; b) the stationary heat conductivity problem for two glued half-segment with sources of heat inside the area. Exact analytical solutions to these new problems have been obtained.
Identificação de adulterantes no leite bovino por meio de redes neurais artificiais e técnica cromática

Published: March 2021

O leite é um dos produtos da agropecuária mais importantes da dieta humana e, ao longo da sua cadeia de produção, fraudes podem ocorrer. As práticas de fraudes no leite bovino são antigas e vêm evoluindo com o decorrer do tempo, tornando-se mais difíceis de serem identificadas. Atualmente, as abordagens para a identificação de adulterantes no leite são caras e demandam muito tempo para disponibilizarem resultados ao usuário. Nesse contexto, uma nova proposta para identificação de adulterantes foi apresentada com resultados promissores, tendo boas vantagens em relação às técnicas existentes, como baixo custo e rapidez. Por meio da propagação de ondas em meio material, ou seja, em amostras de leite puro e contaminado, sinais elétricos foram obtidos a partir de sensores piezelétricos adequadamente dispostos. Através da decomposição dos sinais por técnicas de processamento numéricos, foi possível identificar a existência de contaminantes nas amostras de leite. Nesse cenário, o objetivo deste trabalho foi propor uma abordagem para a classificação dos contaminantes. Para tal, foram estudados três contaminantes: ureia agrícola, bicarbonato de sódio e peróxido de hidrogênio na titulação de 0,5% e 1% tendo como referência o leite do tipo xandô padronizado. Devido à complexidade do problema, sistemas inteligentes baseados em redes neurais artificiais (RNAs) foram empregados a fim de identificar cada um dos contaminantes. Mais especificamente, redes perceptron multicamadas (PMC), rede de reconhecimento de padrões Patternnet e rede de base radial de regressão generalizada (GRNN) foram treinadas e validadas por meio da técnica de validação cruzada. O conjunto de dados continha 700 vetores utilizados em 100% do treinamento, validado com uma amostra de leite puro ou contaminado de 100 vetores, não pertencente ao mesmo banco de dados. Os resultados indicaram que as redes PMC e Patternnet foram capazes de fazer a identificação com a exatidão de 76,43% e 87,86% respectivamente. A rede GRNN apresentou resultados inferiores, além de não conseguir classificar amostras com bicarbonato de sódio. Contudo, a abordagem proposta mostrou-se factível à identificação de contaminantes em leite e pode contribuir na criação de sistemas mais baratos e portáteis para essa finalidade.

Туберкулез (TB) – инфекционное заболевание, вызываемое патогенными бактериями. Бацилла передается в основном через механизм кашля, помимо чихания и речи, которые отвечают за выделение капель слюны. В Бразилии в 2017 году подтверждено 69 569 новых случаев туберкулеза. В бразильском штате Амапа еще в 2017 году было зарегистрировано 237 новых случаев туберкулеза. Цель этой работы – сравнить процент подтвержденных случаев туберкулеза в Бразилии, в Северном регионе, в штате Амапа и в муниципалитете Макапа в период с 2013 по 2017 год. Данные были собраны на сайте DATASUS. Сопутствующие инфекции, а также алкоголизм, употребление наркотиков, городские агломерации и состояние питания человека также могут представлять факторы, увеличивающие заболеваемость туберкулезом. Социальная уязвимость и недостаточность первичной медико-санитарной помощи также способствуют увеличению этих цифр. Наличие Справочного центра по тропическим болезням (CRDT), который также включает в себя Центр тестирования и консультирования (CTA) и терапевтическую помощь на дому (ADT), помогает выявлять случаи, оптимизировать и контролировать лечение пациентов. Мужчины в трудоспособной возрастной группе больше страдают от этого из-за их необходимого социального взаимодействия для работы.

Theory of the Stationary Self-Consistent Universe
Authors: Avshalumov Alexander Shamailovich
Published: March 2021

Since the creation of GR and subsequent works in cosmology, the question of the curvature of space in the Universe is considered one of the most important and debated to this day. This is evident, because the curvature of space depends whether the Universe expands, contracts or is static. These discussions allowed the author to propose a paradoxical idea: simultaneous existence in the Universe of three interconnected space-times (positive, negative and zero curvature) and on this basis, to develop a theory in which each space-time plays its own role and develops in a strict accordance with its sign of curvature. The three space-time model of the structure of the Universe, proposed by the author, allows to solve many fundamental problems of modern cosmology and theoretical physics and creates the basis for building a unified physical theory (including one that unites GR and quantum physics).

Introduction: the Coronavirus disease 2019 (COVID-19) was declared as a global pandemic by the World Health Organization on March 11, 2020. The clinical presentation and severity of the disease has been described from its most typical symptoms, the common cold, pneumonia and respiratory distress syndrome, to the involvement of other organs and systems such such as the gastrointestinal, renal and cardiovascular. Case report: we describe the first case of COVID-19 diagnosed in Cartagena, Colombia, on March 11, 2020, and its uncommon clinic presentation, which was almost unknown at the time. An 85-year-old woman with week-long initial symptoms of nausea and occasional vomiting, with progression to diarrhea and a 38.5 ºC fever during the last three days. The patient came from Oxford, UK, and she had been on a Caribbean cruise excursion since the end of February, 2020. Chest computed tomography showed ground glass opacities in both peripheral and central lung fields, multilobar and predominantly subpleural; without evidence of consolidation or pleural effusion. COVID-19 was confirmed three days after admission, when a RT-PCR molecular test performed on a nasopharyngeal swab sample tested positive for SARS-Cov-2 Conclusion: this first case of COVID-19 diagnosed in Cartagena occurred at a time when our health system was not prepared to face the pandemic. However, despite having manifested with a clinical that had not been described at the time, and thanks to the epidemiological, clinical and imaging data, the case could be adequately approached, diagnosed and treated according to the necessary and recommended measures at the time.
