Published: September 2020

The study was undertaken to investigate the effects of rainy and dry periods on the gross and histological features of ovaries of Oreochromis niloticus in Zaria, Kaduna State, Nigeria. Twenty-four (24) adult wild tilapia fish with average weight of 300.17 ± 25.71 gm and 229.94 ± 23.68 gm was used during rainy and dry periods, respectively. They measured a standard body length of 24.00 ± 0.76 cm and 23.83±0.60 cm during rainy and dry periods, respectively. The fish were sourced from Zaria dam and transported live in open plastic troughs containing clean water to the Gross Anatomy Laboratory, Department of Veterinary Anatomy, Ahmadu Bello University Zaria. Each fish was euthanized using tricaine anaesthetic at 8 drops/litre of water. The ovaries were extracted, weighed and fixed in Bouin’s fluid for 24 hours and processed histologically. Grossly, the ovaries of O. niloticus were highly vascularized and well developed during both rainy and dry periods. The average weight of both ovaries showed insignificant variation across the periods (0.125). The Gonado-somatic index value was insignificantly higher during rainy period (0.115) compared to dry period. Histologically, the ovaries were predominated by vitellogenic and post-vitellogenic follicles across both periods of the year. The tunica albuginea and interstitial connective tissues were thin during both periods. In conclusion, the results in this study revealed that adult wild tilapia fish had developed ovaries with predominant mature follicles during both rainy and dry periods suggesting that adult wild tilapia fish spawns during both rainy and dry periods in Zaria, Nigeria.

Published: September 2020

In this talk we discuss factors that influence and impact Kazakhstani students when it comes to decide major selection.To analyse and study factors,we surveyed 314 students over 16 universities of Kazakhstan (including private, semi-government and government universities). In the previous joint work with (Assanbayeva & Kadyrov, 2020) factor analysis resulted 9 scales,namely,teacher impact,occupation salary impact,external impact,personal interest impact,personal skills impact,national test impact,university cost impact,parents impact,state grant impact.The main aim of the present work is to investigate main factors that influenced the Kazakhstani students most.The next goal is to find any differences in terms of gender when it comes to major selection factors.As most participants were among Suleyman Demirel University,we also wanted to see if there any differences between factors that influence Suleyman Demirel University students major selection to students of other local universities.The statistical data analysis show that students found themselves to be the most influential by 6 factors out of 9 ,namely,influence of state grant, influence of university cost, occupation salary impact, national test impact, influence of personal interest and influence of personal skills.Findings also suggested that, there is no difference between these 6 factors depending on gender.Also,no differences were found among university and factors.
“INVESTIGATE MATHEMATICAL CREATIVITY IN THE FRACTIONS TOPIC IN FIFTH GRADE STUDENTS”
Authors: Assan Meruyert Maratkyzy 
Published: September 2020

The article discusses the methodological problem of familiarizing a younger student with the concepts of "share" and "fraction" in an elementary school mathematics course. In mathematics textbooks for elementary grades, a student receives information about fractions only through a system of practical actions on real objects, quantities and a description of these actions in the language of special mathematical symbols. Teaching fractions is an integral part of the math program. But why are fractions so hard to understand for children? There are three big things that confuse children most often.1. We often ask children to complete a series of steps without understanding the reasons for these steps. Sometimes, when they are younger, students are not even ready for the development of concepts.2. Children often have misconceptions about all the complex topics of mathematics, including fractions. When we can help children resist these misconceptions, learning is often easier.3. Children struggle with fractions for the same reason that children struggle with many new concepts: they just need practice. Examples of such practical actions are given in the article.

Качество процесса оценки деятельности школ и его влияние на показатели работы школ
Authors: Tumlovskaja Jelizaveta 
Published: September 2020

В последнее время система образования Литвы претерпевает важные изменения, переходя к системе, основанной на демократических ценностях. Поскольку Литва интегрируется в европейское пространство, качество образования становится очень важным в функционировании системы образования. Литовские документы по образованию утверждают, что качество образования является договорным понятием (Концепция системы обеспечения качества в формальном образовании, 2008). Ориентиром для разработки понятия качества является Концепция хорошей школы (2015). Вышеупомянутая концепция основана на положениях парадигмы свободного образования и гуманистических ценностях, которые были провозглашены в Концепции национальной школы (1989), созданной накануне независимости. Однако на практике литовские общеобразовательные школы сталкиваются с трудностями при выполнении положений, зафиксированных в документах – как показатели качества деятельности литовских общеобразовательных школ, так и показатели успеваемости учащихся, а также показатели доверия населения к образованию в Литве являются средними. В целях содействия непрерывному управлению качеством в общеобразовательных школах Литвы с 2007 года внедряются процессы оценки качества: самооценка и внешняя оценка. Эти процессы основаны на коллегиальном взаимодействии, диалоге и имеют целью способствовать позитивным изменениям в качестве образования.Ключевые слова: качество образования, оценка качества деятельности, влияние оценки.

Assessment of risk management and evaluate the level of risk in construction project: Case Study
Authors: Husein Akeel A , Majdi Ali 
Published: September 2020

This study illustrates the risk assessment and analysis which was made as a requirement in the beginning of the project of a stadium.Risks at project are classified into ten items so that it is easy to manage and monitor them. Simple model is adopted in assessing risks such that it is easy to be understood and modified in contrast with the complex models that produce misleading. Sharing, mitigation and accepting risk are strategies adopted in the final assessment. In the case of sharing risks, it is shown that contracting strategy must be based on risk allocation. Inplanning for risk, purpose must be clear as well as responsibilities and this can be shown precisely in a form of Risk Plan. The objective that this study serves is to identify the cost needed for the whole project from the stage of design to the finishing works.This includes all facilities in the stadium like the concrete frames, buildings and so. The study was very important to provide information to the contractor (a private company) and made confidence in that the estimated cost and time needed for achieving the objectives of the project are realistic and based on sound information.The experience gained from previous similar projects was an advantage factor in that most of problems were clear. The most important problem was the likelihood of delay, which, in the worst case will lead to dramatic increasing in costs. Therefore, the assessment of this risk was principal task in the study although it is necessary to take care for all potential risks.The study shows that risks at construction projects carried by many parties found to be changing according to internal or external changes and the change of priorities can be seen by simulating changes in ranking in each case. It is shown also that badly risk communication leads to real problems as in the case of making thought of building the stadium to be late. The cost of the delay which is the primary risk was calculated for each part of the project. For the construction activities, these were assumed to be the overhead. The time costs calculated was in maximum ($ 1,500,000) which is about (10%) of the total cost of the project.

Physical Demarcation of Infrastructures and Making Detailed Physical Planning of Kabeza Site
Authors: Jean Pierre Habiyaremye  
Published: September 2020

Physical infrastructure is the basic physical structures required for an economy to function and survive. Rwanda, like other developing countries, its plans focus on the contribution to the solutions of the problems arising due to lack of well-planned local urban upgrading. The infrastructures that allow the access to the services of the population within the country must be maintained, constructed for better achievement of different goals at different levels from the Central Government up to the Sector level. This paper therefore examined the demarcation of the infrastructures and the detailed physical planning as a key component of urban development initiatives. The physical planning sets the boundaries with the purpose of having access to affordable infrastructure services for consumption purposes serves to improve household welfare and affordable housing and promoting a sustainable development for the benefit of the individual, for society and for future generation. The project was conducted in Kabeza Site, Eastern Province, Bugesera District, Ntarama Sector, Kanzenze Cell and Kabeza Village in Republic of Rwanda. Experimental and survey design have used in the assessment of existing physical features around and within the site by observation method using DGNSS Receivers, total stations, and also used participatory approach method. The study involved a detailed topographic survey of existing features on Kabeza site. An interview of stakeholders was conducted during the community meeting. Different software were used to analyze and re-plotting the physical planning. Findings show that the rapid rate of urbanization has led to a rise in informal settlements facing with the problems including lack of sufficient and adequate basic infrastructures. The paper therefore canvassed for immediate evolvement of physical plan that emphasis on keeping commitment to place, establishing the quality recreation areas and diversifying housing options. It was revealed that there is a need to establish a well planned roads, create a more vibrate village centre, light the whole village, establish a water system in the whole village, maintain and upgrade the greening village infrastructures, build community from assessment of the existing land use land cover, make and re-plot the new parcels within the site and to design details physical layout plan of that region. The study recommends the project implementers and partners, particularly the local government units overseeing the project site, to pay attention to the growing income disparity and the exclusion of the poorest from development process. Government should identify measures to minimize the interventions that impact negatively the life of well-being of the poor and women and also to minimize negative impacts on the environment.

Authors: KIRKIK Duygu , AKÇEŞME Faruk Berat , KALKANLI Sevgi 
Published: September 2020

Introduction: Cluster of differentiation 40 is a type I transmembrane protein present on B cells, macrophages, dendritic cells, and endothelial cells, which leads to cell activation, proliferation, adhesion or differentiation. Previous studies have been shown that cluster of differentiation 40 polymorphisms have an effect on some autoimmune diseases. The purpose of this study is to investigate all single nucleotide polymorphisms found on cluster of differentiation 40 gene and their relationship with possible diseases by bioinformatics methods.
Material and Method: In our study, while GeneMANIA was used to investigate the relationship between cluster of differentiation 40 gene with other genes, SIFT was employed to select sequences with similar functions as cluster of differentiation 40 gene. Exome cariant server was used for the detection of changes between populations and suspected single nucleotide polymorphisms. Mr single nucleotide polymorphisms Software was used to predict the effect of binding of 3’untranslated regions single nucleotide polymorphisms to miRNA. In order to analyze the untranslated regions on single nucleotide polymorphisms, UTRscan tool was used. UbPred was used for the estimation of the potential ubiquitination site on proteins, and Prosite was used to define the functional characterization of the protein domain.
Results: In our study, a total of 85 single nucleotide polymorphisms were found for cluster of differentiation 40 gene, and rs147677886, rs11569321, rs7273698, rs11086998, and rs139300926 were detected as suspected single nucleotide polymorphisms. Moreover, these single nucleotide polymorphisms may be associated with multiple sclerosis (MS), rheumatoid arthritis (RA), and Kawasaki disease.
Conclusion: Currently, there are no studies in the literature about single nucleotide polymorphisms of cluster of differentiation 40 gene that we detected by bioinformatics methods. In the future, we aim to evaluate this study experimentally in the laboratory and contribute to population-specific studies.
