Authors: SUBAŞI Mehmet
Published: December 2020

Toz enjeksiyon kalıplama (TEK), metal ve seramik tozlarından hassas geometrili parçaların üretimi için kullanılan ideal bir tekniktir. TEK yönteminde parçanın iç kısmında vida geometrisi elde etmek için hareketli maça sistemine ihtiyaç vardır. Fakat bu sistemin yapılması hem zor hem de zaman alıcıdır. Bu çalışmada iç vida geometrisi, parça içerisindeki insört ile elde edilmeye çalışılmıştır. Bunun için, 316L paslanmaz çelik besleme stoku kalıp içerisine enjekte edilerek parça üretilmiş sonrasında uygun matkapla delik delinmiş ve M4 vida çekilmiştir. Parça içerisine konulacak vida geometrili insörtler yüksek sıcaklığa dayanıklı hegzagonal bor nitrür ve krom ile kaplanmıştır. Böylece besleme stoku bölgesindeki vida geometrisinin insört ile difüzyonunun engellenmesi amaçlanmıştır. Hazırlanan numuneler iki farklı sinterleme sıcaklığı (1260 °C - 1340 °C) ve süresin de (30-90 dakika) sinterlenmiştir. Çalışma da insört üzerine uygulanan ara katmanların vida geometrisine etkisi araştırılmıştır. Deneyler sonucunda vidalı insört üzerindeki hegzagonal bor nitrür ve krom ara katmanlarının difüzyonu engellemediği belirlenmiştir.

Zearalenone Removal by Using Banana Peel as an Adsorbent
Authors: Shar Z. H.
Published: December 2020

Zearalenone (ZEA) is the most occurring Fusarium toxin in animal feed causing reproductive disorders and results in severe economical losses. A renewable bio adsorbent sourced from banana peel was tested for in vitro removal of ZEA from liquid mediums at different pH values. Efficacy of banana peel to sequester ZEA was evaluated by varying its pH, adsorbent dosage, equilibration time and quantified by using UHPLC-MS/MS. Adsorption was found to be efficient and completed in fifteen minutes with highest adsorption at alkaline pH (9). The adsorption and desorption studies have demonstrated the adsorption was strong enough to sustain the pH changes (3-9). Fourier transforms infrared spectroscopy (FTIR) and scanning electron microscope (SEM) was used to characterize the surface of bio sorbent to explain the mechanism of adsorption. Langmuir and Freundlich isotherm was found to be best fitted model with maximum monolayer capacity (Q0) 8 ng/mg. The results of this study suggested that dried banana peel may be an effective low cost decontamination method to be incorporated in animal feed.

Authors: Ali Anila , Mohamad Hussain Roslinah , Dahlan Akehsan , Asghar Ali
Published: December 2020

Motorcyclists (n=26) average noise exposure levels (LAeq) were found substantially different for OSHA-HC (85 dBA), OSHA-PEL (78 dBA) and ACGIH/NIOSH (87 dBA) noise standards. A significant difference in LAeq, (p=.027) and engine capacity usage (p=.045) was found amongst gender. However, no observable association was found between the LAeq and motorcycle engine capacity (p= .462) and completion of a ride (p= .695). Thus, female riders were inclined to use lower motorcycle capacities, rode at lower speeds which resulted in lower noise exposure levels, in concurrence with longer ride durations. Overall, motorcyclists’ noise exposure level functions with the increasing speed (80km/h: 88 dBA).

Estimation of wind soil erosion in a semiarid region of Mexico
Authors: Guevara-Macías María de Jesús , Carbajal Noel , Pineda-Martinez Luis
Published: December 2020

Land degradation is a global problem. One of the main factors of this
degradation is intense winds in the world’s arid and semi-arid regions.
The wind acts on soils without vegetation cover in increasingly large
regions. The impact of dust storms is considerable, from massive soil
deterioration to health problems. In the arid regions of northern and
central Mexico, the problem of changing land use from grasslands and
forests to rainfed agriculture has increased notably in recent decades.
Recurring dust storms due to winds associated with the passage of cold
fronts have become a severe environmental problem. The Weather Research
and Forecasting Model (WRF-Chem) was applied to analyze dust storms that
occur mainly during the winter. An analysis was performed for wind speed
data in the period from October 2005 to April 2018. It revealed that
about 20 events per year exceeded a threshold erosion speed of 9 m/s.
Fifteen events with the potential to generate dust storms were selected.
The total amount of dust emitted was added together, and an average dust
storm was calculated. Since the massive land-use change began
approximately 50 years ago, a total erosion effect was estimated for
this period. The characterization of eight soil samples revealed the
texture of fine silty sands with low clay content and low organic
content due to the mechanical processes of removing the finest fraction.
Comparison between observed and modeled dust storm events showed good
agreement.

Authors: Anwar Adnan , Razzaq Mudassar , Rivkind Liudmila
Published: December 2020

As an example of an aerodynamics prototypical study, we examined a
two-dimensional low Reynolds number flow over obstacles immersed in a
stream of infinite extent. The Navier Stokes equation is being
discretized by non conforming finite element method approach. The
resulting discretized nonlinear algebraic system is being solved by
using the fixpoint method and the Newton method and multigrid method for
the linear sub-problem employed. The magnitude of the uniform upstream
velocity under the study of the problem for Reynolds number in the range
1 < Re < 100 and the angle of attack of the upstream
velocity at α = -5; 0; 5 degrees performed. Analysis of the resulting
drag and lift forces acting on obstacles with respect to the angle of
attack of the upstream velocity and the Reynolds number is made.
Moreover, the influence of one obstacle on the resulting drag and lift
coefficients of other obstacles determined. The results are being
presented in a graphical and vector form.
Impact of p53 modulation on interactions between p53 family members during HaCaT keratinocytes differentiation
Authors: Rusanov AL , Kozhin PM , Romashin DD , Karagyaur MN , Luzgina NG
Published: December 2020

HaCaT cell line is a widely used model for studying normal human keratinocytes. However, mutations of TP53 gene are typical for this cell line, which have a substantial impact on functions of the encoded protein. The features of this regulatory circuit should be considered when using HaСaT cells for assessment of human skin physiology and pathology in vitro. The study was aimed to assess the features of differentiation realization in HaCaT cells with modulated activity of p53 protein. The expression of p53 was reduced by knockdown of TP53 gene by shRNA (by 2.2 times, p < 0.05), and the elevated concentration of the p53 active forms was achieved via exposure of cells to Nutlin-3a, the MDM2 inhibitor and the major negative regulator of p53. It has been found that regulation of at least three differentiation markers, СASP14, IVL (expression increase by 3.9 and 3.7 times respectively in the p53-knockdown cells, p < 0.05) and TGM1 (twofold expression decrease in the p53-knockdown cells, and 1.7-fold expression increase under exposure to Nutlin-3a, p < 0.05) in HaCaT cells is p53-mediated. The positive correlation has been revealed for expression of TGM1 and p53 that might be realized indirectly via ΔNp63 expression alteration. At the same time, modulation of p53 does not result in significant alterations in expression of cytokeratins.
Simbolisasi Warna dalam Al-Quran
Authors: Hidayat Hamdan
Published: December 2020

This article aims to discuss the symbolization of colors in the Qur'an. In the article, the symbolism of colors in the Qur'an is discussed using the thematic interpretation theory pioneered by Abdul Hay al-Farmawi. Through this thematic interpretation, theory found 6 colors found in the Koran, namely red, yellow, green, blue, black, and white scattered in 33 ayat contained in 22 surahs by mapping the results of research using thematic analysis techniques. The results of color research in the Qur'an are expressions that are marked with color in various forms of lafadz as a symbol to describe certain objects in a situation, situation, place, and nature of the object. First, read as a symbol of the beauty of nature. Second, yellow is a symbol of the image of humans in the world. Third, green is a symbol of fertile earth. Fourth, blue as a symbol of the human condition on the Day of Judgment. Fifth, black is a symbol of human images on the Day of Judgment. Sixth, white is a symbol of a human image when in heaven. The existence of this article shows that color is a simple but meaningful symbol hidden in the Qur'an which needs to be studied.

A survey of steganalysis methods in the papers of foreign authors
Authors: Vilkhovskiy D. E.
Published: December 2020

The paper provides a survey of foreign studies regarding steganalysis, aimed to detect hidden message insertion made by applying least significant bit replacement and discrete cosine transform algorithms. It is noted the further steganalysis methodology development splits in two directions: a decrease of the complexity and cost of processing and detection while maintaining a high level of classification rate, which is quite justified in the case of the presence of insertions with a large payload, i.e. up to 100%; or an increase of the insert recognition efficiency when dealing with images of a low payload. Besides, during the last five years, steganalisys methods based on machine learning and deep learning began to play a dominant role in steganalysis
ESL/EFL online lesson development (based on Skyeng practices and techniques)
Authors: Smyshlyak K. V.
Published: December 2020

The article presents an attempt to infer the key stages of creating an effective online English lesson based on corporate teaching practices and techniques of Skyeng online school. There have been revealed some important aspects that are to be taken into consideration when working out an online lesson structure and content. Having analyzed various theoretical courses on communicative language teaching methods and having combined them with the incorporated Skyeng practice in teaching English as a Second Language or English as a Foreign Language (ESL/EFL), we have come up with a certain algorithm which we advise to apply in lesson modelling: focusing on achievement aims rather than procedure aims, choosing the correct lesson structure, evaluating the studying materials and content, formulating methodological sections to aid the teachers. There have been presented some language management techniques currently used in Skyeng lessons, such as the correct formulation of the instructions, balancing teacher talking time and student talking time and the technique of a guided discovery. The practical application of Blooms’ taxonomy is illustrated in the example of additional speaking tasks and their correct development. There have been described such notions as: achievement aims, materials’ evaluation, TTT and STT balance, guided discovery, lesson content units, Blooms’ taxonomy, lesson structure. The article contains practical examples of how these notions are realised in the lessons developed in Skyeng online school. Though all the examples are shown in the paradigm of an online lesson, the same algorithm presented in the article is highly recommended when developing offline lessons which are traditionally held in a classroom. Thus, there has been made an attempt to work out a single algorithm for modelling effective online and offline ESL/EFL lessons.
The use of revenue-based multipliers for the appraisal of oil and gas companies
Authors: Shimko O.V.
Published: December 2020

Subject. The article focuses on ratios of the market capitalization and corporate value to revenue of the twenty five leading public companies in the oil and gas sector within 2008 through 2018.
Objectives. The study is to trace key trends in ratios of corporations in the oil and gas. I also determine what caused such a transformation for the analyzable period and whether the multipliers are applicable to appraise the corporate value in the oil and gas sector.
Methods. The study is based on methods of comparative and financial-economic analysis, summarizing financial reporting data.
Results. Revenue-based ratios are found to be applicable to appraise the value of oil and gas companies. Although having the similar composition of net revenue, companies with better profitability have higher multipliers. Integrated corporations were found to have lower multipliers than independent companies. The study shows that the import-based petrochemical production tends to have the lower value than that using domestic resources. The multiplier goes down if the company's revenue includes proceeds from the resale. As the debt burden grows, the multiplier decreases. Therefore, considering the significant difference in the debt burden, the multiplier should better include the corporate value instead of the market capitalization, since the corporate value comprises the net debt. I also discovered the country-related factor, which should be taken into consideration when using the multiplier.
Conclusions and Relevance. The use of revenue-based multipliers requires the thorough analysis of the financial and business operations of companies. However, it is quite acceptable when the overall profitability decreases and the debt burden increases in the public segments of the global oil and gas industry. The findings can be used to appraise the value of oil and gas assets as part of the comparative approach and decide on actions for raising the market capitalization of public oil and gas corporations.
The impact of the COVID-19 pandemic on startup finance: Considerations on the situation and aspects for the State aid
Authors: Kozhanova A.V.
Published: December 2020

Subject. The article investigates how crises influence the finance of SME and startups, and what the State does to support them.
Objectives. The article outlines lines of the governmental policy for startup finance so as to maintain the innovation-driven economy during the crisis caused by the COVID-19 pandemic.
Methods. The study is based on the critical systems analysis of economic literature (research papers, reports of consulting companies and professional experts). I also apply methods of observation, collection of facts, synthesis, etc.
Results. I outlined aspects of the governmental policy for startup finance during the COVID-19 pandemic: supporting the startups that just assumed their life cycle, the State should provide more direct finance, use special governmental funds and departments of State-owned companies, give more grants; supporting any startups notwithstanding their life cycle, the State should adopt some tax benefits in strategic sectors, simplify financing procedures in governmental funds and State-owned companies, lower interest rates on finance provided by State-owned banks.
Conclusions and Relevance. The findings can be used by governmental institutions, which deal with SME, startups and innovative economy, inter alia, to outline programs, strategies, regulatory documents.
Assessment criteria for aggregate social welfare
Authors: Moskal'onov S.A.
Published: December 2020

Subject. The article addresses the history of development and provides the criticism of existing criteria for aggregate social welfare (on the simple exchange economy (the Edgeworth box) case).
Objectives. The purpose is to develop a unique classification of criteria to assess the aggregate social welfare.
Methods. The study draws on methods of logical and mathematical analysis.
Results. The paper considers strong, strict and weak versions of the Pareto, Kaldor, Hicks, Scitovsky, and Samuelson criteria, introduces the notion of equivalence and constructs orderings by Pareto, Kaldor, Hicks, Scitovsky, and Samuelson. The Pareto and Samuelson's criteria are transitive, however, not complete. The Kaldor, Hicks, Scitovsky citeria are not transitive in the general case.
Conclusions. The lack of an ideal social welfare criterion is the consequence of the Arrow’s Impossibility Theorem, and of the group of impossibility theorems in economics. It is necessary to develop new approaches to the assessment of aggregate welfare.

Published: December 2020

Over the period, several medicinal plants are recognized as attractive sources of anti-cancer molecules. About 35,000 plant organisms have been tested for possible anticancer activities by the National Cancer Center (NCI).  Among them, reproducible anticancer behavior has been shown by around 3,000 plant organisms. Based on this information, we aimed to investigate the cancer preventive efficiency of Polydatin encapsulated PLGA nanoparticles (POL-PLGA-NPs) against 7,12 dimethylbenz (a) anthracene (DMBA) induced buccal pouch carcinogenesis by modulating the antioxidants process in male Syrian hamsters. Oral cancer was initiated on left side buccal pouches by applying DMBA (0.5%), (a known potent chemical carcinogen) on alternative days in a week (thrice a week) for a period of 14 weeks to provoke oral cancer.  Sequences of oral squamous cell carcinoma are noted to be manifested exhibiting the formation of incidence, size, mass and development of tumor presented as preneoplastic and neoplastic lesions in hamsters oral buccal pouch tissues.  At the same time, oral administration of POL-PLGA-NPs (30mg/kg.b.wt.) considerably increased glutathione peroxidase (GPx) and glutathione (GSH) levels in the buccal tissue thereby decreasing lipid peroxidation activity which resulted in neoplasms incidence in buccal tissue of DMBA painted animals. Thus, POL-PLGA-NPs activity seemed to be a potent cancer preventive agent.

To use flax oil in food, it is necessary to decrease the content of linolenic acid. We developed the oil flax variety Amber by individual selection from the hybrid population of the 3rd generation from crossing of the low-linolenic variety Linol and the breeding line 34725. The variety is mid-ripening, the duration of its growth season is 90-98 days, it is well adapted to the soil and climatic conditions of Siberia. It differs from the standard variety by its low content of linolenic acid in oil – 4.8-6.3 %. According to the results of competitive variety testing in 2016-2018, the variety Amber exceeded the standard variety Severny in terms of seed productivity by 0.29 t/ha. The variety ripens in uniformity, it is resistant to Fusarium blight, lodging and shedding, it is suitable for mechanized harvesting, it is developed to obtain edible oil of high quality. The potential cultivation areas of the oil flax variety are Volgo-Vyatsky region, Ural and West Siberia.

A simple sunflower hybrid Taizar was developed at V.S. Pustovoit All-Russian Research Institute of Oil Crops as part of a breeding and genetic program for developing highly productive hybrids resistant to the new virulent races of broomrape by using the method of backcrossing in combination with an evaluation of resistance in each generation for the target gene Or7. The hybrid Taizar is of mid-early group of ripeness, it has a high yield, it is resistant to Orobanche cumana Wallr. (races A-G) and downy mildew (races 330, 710, 730, 334, 734). The line-restorer of pollen fertility VK 305 is the paternal form of the hybrid Taizar. The line was developed as a result of the introduction of the Or7 gene from the RG line by two backcrosses into the line VK 303, subsequent inbreeding and selection of broomrape-resistant genotypes. The line VK 305 has narrow widely spaced ray flowers strongly curved towards the back of the head, which can serve as a morphological marker of genetic purity.

The article is dedicated to the examination of such a ground for refusal of recognition and enforcement of decisions of international commercial arbitration in Ukraine as the infringement of public policy. The author describes some approaches to the definition of the content of the term «public policy» basing on the examination of court practice from 2018 to 2020 and doctrinal sources. Particular attention is focused on the determination of the criteria which may be used for identification of the areas of social relations which form public policy. The author also pays attention to some criteria, whose usage may be helpful and effective in determining whether or not the infringement of public policy exists on conditions that a decision of international commercial arbitration is enforced. The author analyses some court decisions in order to inquire the position of national courts when deciding on giving a permission or refusing to recognize and enforce a decision of international commercial arbitration if a disputing party as a ground for refusal indicates the infringement of public policy.

In this article it was found that the importance of agricultural development is due to the direct impact of this area on the living standards of citizens, which largely depends on the welfare of the population, including per capita income and social living conditions. It is proved that providing organizational, legal and economic measures for sustainable development of agricultural production will provide an opportunity to increase production of relevant products, improve its quality and safety, and, consequently, its competitiveness, both domestically and internationally. It is analyzed that despite the focus on the development of other sectors of the economy, in particular, technology, in most developing countries much of the territory is occupied by the agro-industrial sector, and among the population from 70 to 90% are employed in agriculture. Therefore, it was proved that the development of agriculture will always be relevant and require attention from scientists in various fields of science. This article noted that the structure of the agricultural sector, as well as the specific set of mechanisms of state regulation in different countries is different. At the same time, it is noted that some countries seek intensive development of this sector of the economy, while others suffer losses. In the presented article we have analyzed the current state of agriculture in Ukraine and identified problems that stand in the way of its development; In order to solve the existing problems, the experience of advanced foreign countries, including the United States, the European Union, Canada and Japan, was analyzed, and the factors due to which these countries managed to achieve stable growth in agriculture were identified. Based on the research, practical recommendations were provided, which we propose to take into account in the formation of state regulation of the agricultural sector in Ukraine.

The article describes the various levels of legal regulation of the grain market in Ukraine and abroad, that is, grain export to other countries. We are talking specifically about legal acts of various legal force: from subordinate normative legal acts to international conventions. This research also reveals the issues of the current state of the grain market in Ukraine from growing grain to selling it both domestically and abroad. The process of production and sale of grain covers a large number of entities that conduct their activities: subjects of growing, storage of grain, various government authorities and specialized institutions that contribute to the development of such a market and provide minimum guarantees from the state for the relevant entities to carry out their economic activities. The state, realizing the importance of this institution, which contributes to an increase in the State budget of Ukraine, establishes the appropriate standards that govern the procedure for growing grain, its storage and sale. As you can see, the processes are complex, respectively, and the legal regulation of such processes covers a large number of regulatory legal acts. That is, the state controls this issue and sets the rules of the game. Realizing the importance of such processes, one cannot but pay attention to the state support of the grain market. Thus, the relevant specialized institutions can provide financial support to grain producers on a refundable or non-refundable basis, at the level of the law, a simplified taxation system and preferential customs tariffs have been established. That is, at the state level, certain steps are being taken that contribute to the development of the grain market in Ukraine. The work also analyzes the international legal acts to which Ukraine is a party, their impact on state policy and on the grain market itself, as well as the prospects for the development of such a market.

This article is devoted to a comparative analysis of the legislation of Ukraine and the EU in the field of legal regulation of waste management. The requirements for approximation of the legislation of Ukraine and the EU in the context of the Association Agreement between Ukraine, on the one hand, and the European Union, the European Atomic Energy Community and their Member States, on the other hand, are considered. This process is detailed, with the establishment of specific deadlines for the implementation of certain provisions of EU law in Ukrainian law, in Annex XXX to the Association Agreement. Approaches to the establishment of the concept of «waste» in national legislation are noted, it is emphasized that various regulations provide a different definition of this concept and established as defined by EU legislation, a key component of which is the concept of disposal, which aims to solve the problem of homelessness. waste. A number of solutions regulating the classification of waste in the European Union are considered, in particular the existence of the so-called List of waste. Emphasis is placed on the imperfection of the waste classification process in Ukraine, as the Waste Classifier DK 005- 96 does not establish the degree of harmful effects of waste on the environment. The requirements set out in the main Directives governing waste management have been studied. The principles of waste management are considered, in particular, which is enshrined in Directive 75/442/EEC. The National Strategy for Waste Management in Ukraine until 2030 is studied, which identifies the main directions of state regulation in the field of waste management, taking into account European approaches, which are based on key Directives in this area. The strategy stipulates that the normative documents that will be developed and adopted for its implementation should be based exclusively on the principles and provisions of the relevant acts of European legislation.

The article examines the level of development of the e-government system in Ukraine, taking into account the most important trends associated with active digitalization processes. Another important element of the present study is the analysis of international approaches to the implementation of e-government, including the position of the United Nations. The article considers theoretical and methodological research in the fields of public administration and public administration, takes into account the views and concepts of leading scientists in these fields. In particular, an integral element of the study is the analysis of national legislation, especially regulations governing the circulation of information, namely: On the National Informatization Program, On the Basic Principles of Information Society Development in Ukraine. In addition, the legislation formulates a strategy for the development of public administration and public administration (On approval of the Concept of e-government development in Ukraine: order of the Cabinet of Ministers of Ukraine, On approval of the Information Society Development Strategy in Ukraine: order of the Cabinet of Ministers of Ukraine). In particular, the relevant regulations were analyzed in detail in order to find in them plans and concepts for further development of e- government in Ukraine.

Published: December 2020

The article focuses on the use of international standards in the application of sanitary and phytosanitary measures. A comprehensive analysis of scientific literature allows us to conclude that the problems of European integration were studied in the works of a number of domestic scientists. In their works they reach similar conclusions that national legislation should be updated as quickly as possible and adapted to the international legal obligations undertaken by Ukraine to the WTO and the EU in terms of aligning sanitary and phytosanitary requirements with international standards in this area. This fact, at the doctrinal level, recognizes the powerful impact of international law on the development of domestic agrarian legislation. Particular attention is paid to Chapter 4 "Sanitary and Phytosanitary Measures" of the Association Agreement with the EU and the Comprehensive Implementation Strategy of Chapter IV (Sanitary and Phytosanitary Measures) of Section IV "Trade and Trade-Related Issues" of the Association Agreement, which provides for measures to implement (total 70), terms of their preparation and implementation. Based on the analysis of the legal features of international standards in the field of sanitary and phytosanitary measures, the author identifies and reveals the content of such characteristic features as: the presence of a recommendatory nature; indirect action by making them the basis of national legislation; acting as an important tool for harmonization (or unification) of provisions of national legislation on the application of sanitary and phytosanitary measures; weak ability to influence the development and change of international standards in the field of sanitary and phytosanitary measures; presumptions of consistency of measures are applied taking into account international standards.
