SOCIO-ENVIRONMENTAL ASPECTS OF PROVISION OF LANDSCAPING IN THE CITY OF CHERNIHIV
Authors: Zapototskyi S. , Zapototska V. , Holub Y.
Published: December 2020

Chernihiv is a large city in the north of Ukraine, which has been the center of socio-cultural and political life of Ukrainians since the times of Kyivan Rus’. Today, it is an industrial and cultural center, an important transport hub. In recent years, positive changes have been observed in the socio-economic development of Chernihiv. The article reveals the main features of urban development. Its tasks and main elements are described. The situation related to the state of air pollution, water resources, including in Chernihiv, was analyzed. The main sources of environmental pollution are described. The problem of solid waste management in the city is considered. Urban noise has been described as a factor in air pollution that adversely affects human health. The effect of insolation within the city is characterized, the consequences and requirements for its consideration in the planning of cities, districts or neighborhoods are indicated. The analysis of the aeration regime of the city territory as a factor influencing the comfort of living in the city is carried out. The role of green plantations is determined, which is an important element of the natural environment and improvement of urban space. Three types of comfort in the city (ecological, social and urban) are described and their main features are pointed out. Our vision of a comfortable city, which should be compact, convenient and polycentric, to provide equal access to benefits to different segments of society, is proposed. The industrial complex and the reasons for the decline in the pace and volume of industrial production in some previously leading industries are described. The main enterprises of Chernihiv that imple­ment modern technological solutions are identified. The transport complex of the city and tendencies of its further development are considered. An analysis of health, education, culture and recreation facilities, as well as the situation in the social sphere of Chernihiv. An analysis of a sociological survey among the city’s residents on the improvement problems which concern resi­dents the most has been carried out. This study showed that the most pressing issues for citizens are garbage removal and household waste management, the problem of heat supply and public transport. An analysis of respondents’ responses re­vealed that they support positive trends in the creation of new sports and children’s playgrounds, but want these facilities to be within walking distance of their place of residence. Most citizens are satisfied with the work of the city authorities to address the issues of improvement and comfort of Chernihiv, hoping for further positive changes. The paper identifies the priority areas of development of Chernihiv for the coming years. Among them: improving the living standards of the population, improving the environment, further economic growth, increasing employment in the city, updating and creating new quality infrastructure, supporting small and medium-sized businesses.
Using Storytelling for Counseling With Children Who Have Experienced Trauma
Authors: Mendoza Krystyne , Bradley Loretta
Published: December 2020

This article presents a fictional case study that illustrates the use of a model for storytelling, focusing on counseling with traumatically abused children. A review of information on child welfare is presented with a historical account of expressive modalities used in the therapeutic context when working with children. Since stories provide a developmentally appropriate means of communication, a brief review on the efficacy of using storytelling techniques with children is also provided. While the value of stories is inherent and commonly known, formal methods for utilizing stories in counseling are lacking. This article creates a foundation in which counselors can embrace storytelling as they seek to understand the stories with which children work. A fictional case vignette further illustrates the use of a model for storytelling.
Podcasts as an Evolution of Bibliotherapy
Authors: Casares D. Robert , Binkley Erin E.
Published: December 2020

For over a century, clinicians have utilized a variety of written materials—a practice traditionally referred to as bibliotherapy—to address a diverse range of client issues and facilitate the process of growth, healing, and change. Recently, podcasts have experienced a dramatic increase in popularity and cultural influence, which has allowed the medium to expand access to learning information that was once primarily delivered in print media. Through a review of current digital media trends, relevant academic literature, and several clinical applications, this article highlights the suitability of podcasts to function as an evolution of the traditional practice of bibliotherapy and provides guidelines for effectively selecting and integrating podcasts into clinical practice.
Culturally Adapted Cognitive-Behavioral Therapy in the Treatment of Panic Episodes and Depression in an African American Woman: A Clinical Case Illustration
Authors: Wallace Donya D. , Carlson Ryan G. , Ohrt Jonathan H.
Published: December 2020

African American women experience multiple factors that increase their risks of developing mental health disturbances, particularly depression and panic episodes. Effective treatment of these disorders requires adaptation of evidence-based treatments to demonstrate cultural competency. Adapting theoretical approaches to meet the cultural needs of African American female clients by incorporating their preferred coping methods into treatment is one example of genuine regard and culturally responsive clinical practice. In this paper, we provide a review of relevant literature describing unique considerations for working with African American women, as well as a case illustration to highlight the implementation of culturally adapting cognitive-behavioral therapy (CBT) in the treatment of panic episodes and depression with an African American woman. A session-by-session protocol outlines how to adapt CBT to meet the client’s coping preferences of spirituality, family, and community.

Published: December 2020

Objective: The purpose of this study was to determine if gas tension and acidity levels could serve as biomarkers of pulp inflammatory status in primary dentition. Study design: The present study evaluated acidity level and blood partial pressures of O2 and CO2 collected from vital pulp chambers of 84 primary molars with deep carious lesions encroaching the pulp. Teeth were treated with pulpotomy or pulpectomy based on clinical judgement. Pulpectomy was performed when symptoms of spontaneous pain, difficulty in obtaining hemostasis and/or dark purple blood were present. Using a glass capillary, pulp chamber bleeding was collected and within ten minutes a neonate Astrup test was performed to determine blood gas module pH, pCO2, and pO2. Results: Eighty-four children with one affected tooth participated in the study (37 girls and 47 boys). Age ranged between 3.5 to 9-years (average: 5.3 years). Seventy-one (84%) were treated with the aid of inhalation analgesia, conscious sedation or general anesthesia. Pulpotomy was performed on 58 teeth (69%). Teeth undergoing pulpectomy revealed significant higher level of CO2 partial pressure (P= 0.002). Acidity level values (pH) were also lower but none significantly in teeth with pulpectomy (P= 0.137). Conclusions: Higher pCO2 levels was found in pulps needing pulpectomy.
«The Constitution of Karel Kramář»: A Draft of Presidential Republic for Russia
Authors: Zainutdinov D. R. , Gataullin A. G.
Published: December 2020

Abstract. The paper is devoted to the examination of the possibility of establishing a presidential republic in Russia after 1917. The authors have investigated the legal stance of the conservative-liberal and liberal-democratic camps in relation to the applicability of the American constitutional model for the organization of the highest executive power. The main part of the study is devoted to the analysis of the draft “Constitution of the Russian State” compiled by the Czech statesman Karel Kramář. The paper has examined the rules of the “Constitution of the Russian State” devoted to the legal status and powers of the Head of State. The study methodology includes such general scientific methods as analysis, comparison, techniques of logic, etc. Private legal methods allowed the authors to reveal and explain the meaning of the “Constitution of the Russian State” (the method of legal hermeneutics), as well as to compare the legal categories and institutions Karel Kramář used to form a presidential republic in Russia (the comparative-legal method). The authors conclude that the draft “Constitution of the Russian State” became one of the specific reflections of “white” constitutionalism.
The Two-Level System of Power of the Federal State
Authors: Romaikin I. A.
Published: December 2020

A contemporary theory of the state and law considers the two-level system of power as an indispensable feature of federal states. The interpretation of this organizational feature of state power depends on how the sovereignty of the federal state is interpreted, the nature of federal relations, the federal form of government itself. The purpose of the study is to identify the essential features of the two-level construction of the power system in the federation, characterize both levels of state power and their relations between each other. As a result of the study, the author highlights the concept of two-level construction of state power, describes the reasons for this structural feature of the power system, demonstrates the internal logic of relations between federal and regional levels of government in the general context of the federal model of the state structure. The study of the state power features in the federation allowed the author to look at the essence of federalism “from the inside”, from the point of view of the system-structural organization of the power apparatus. The two-level system of power appears as an internally agreed way of organizing the state mechanism, where every level has the functions and characteristics inherent only to it and that in their interaction reveal the main meaning of the federal structure— the preservation of state integrity.
Constitutional Law Foundations for the Restriction of Human Rights in Connection with the New COVID-19 Pandemic
Authors: Doroshenko E. N.
Published: December 2020

The paper investigates the issue of legal grounds for introducing restrictive measures in order to protect the population in the territory of the Russian Federation in connection with the spread of a new coronavirus infection. Complying with the requirements contained in the decrees of the President of the Russian Federation, the highest officials of the constituent entities of the Russian Federation have issued decisions on the introduction of the high-alert regime, including prohibitions on implementation of certain economic activities, free movement of citizens and vehicles, mass events. Despite the adoption of relevant amendments, federal legislation in the field of protection of the population from emergencies, as well as other federal laws have not defined conditions, terms and the scope of possible limitations. Therefore, the implementation of constitutional human and civil rights was subject to the content of the by-laws. Analysis of Art. 55 and 56 of the Constitution of the Russian Federation allows the author to enunciate the basic requirements for the system of restrictive measures to combat the spread of infection and identify its shortcomings.
The Convention for the Protection of Human Rights and Fundamental Freedoms in the System of Sources of Legal Regulation of the Administration of Justice in Administrative Offences
Authors: Pankova O. V.
Published: December 2020

The paper presents the author’s view of the problem of interaction between international and national administrative law and attempts to determine the place of the Convention on the Protection of Human Rights and Fundamental Freedoms in the Russian legal system and the administrative and tort legislation of the country. Based on the analysis of different points of view, the conclusion is enunciated that international treaties ratified by the Russian Federation are incorporated into the general body of administrative legislation; and they constitute a source of administrative law in the part in which they contain legal provisions governing the administrative and legal status of citizens, as well as guarantees of its implementation, including guarantees of equitable justice in cases arising from public law relations and administrative and tort cases. In this regards, the author analyzes the provisions of Article 1.1 of the Administrative Code of the Russian Federation, determining the place and role of universally recognized principles and norms of international law and international treaties of the Russian Federation in the system of sources of administrative and tort law—the author refers the Convention for the Protection of Human Rights and Fundamental Freedoms to the sources mentioned above. The paper considers this Convention as an international treaty of the Russian Federation that not only regulates interstate relations, but also actively invades the regulation of procedural administrative responsibility, since it establishes the general parameters of a fair trial in administrative and tort cases. The paper also pays attention to the implementation in the draft Code of Administrative Offences of the Russian Federation and the Procedural Code of the Russian Federation on Administrative Offences of the Constitutional Principle concerning international legal norms in the legal system of the Russian Federation.

Legality of Dismissal of Employees Working Irregular Hours for Appearance at Work in a State of Alcoholic, Narcotic or Other Kind of Intoxication
Authors: Tsypkina I. S.
Published: December 2020

The paper analyzes the issues related to irregular working hours, which arise due to the lack of proper legal regulation of this legal category. The author emphasizes that the inclusion of the irregular working hours provision into the employment contract is primarily determined by the employee’s labor functions, since it is the performance of this labor function that conditions particular working hours as the regular working hours may be not enough. In addition, the paper highlights the problem of the permissibility of establishing irregular working hours for pregnant women and persons for whom reduced working hours are established. The author concludes that the spread of the rule regarding the possibility of drawing a parallel between the restrictions provided for by Art. 99 and 101 of the Labor Code of the Russian Federation currently has no legal basis. In this regard, the author attempts to find ways to resolve this problem. The paper identifies controversial and ambiguously resolved in law enforcement issues that arise when resolving labor disputes related to the termination of an employment contract with an employee who is at work in a state of alcoholic, drug and other kind of intoxication, outside the established duration of working hours. For the purpose of uniform application of the current legislation, it should be assumed that for workers with irregular working hours, all the time they are at work is considered work time.
Theoretical and Practical Issues of Minor Suspect or Accused Supervision in the Russian Criminal Proceedings
Authors: Matveev S. V. , Kulakov P. V.
Published: December 2020

The paper examines the main theoretical and practical issues that arise when choosing such a special measure of restraint in relation to a minor suspect or accused as supervision. The authors emphasize that due to legislative gaps and the lack of a clear algorithm of actions for its application, this measure of restraint is rarely applied in practice. The paper touches upon the topic of the participation of adults in the supervision of a minor suspect or accused. In particular, the authors conclude that it is impossible for the guardian to participate in these criminal procedural relations. The study and analysis of scientific literature allowed the authors to develop criteria which may help determine whether it is possible to admit an adult person to supervise a minor suspect or accused. It is stated that in order to increase the number of supervision application in respect of minor suspects and accused in comparison with other preventive measures, it is necessary to legislatively revise the provisions of the criminal procedure law and recommendations given in the resolutions of the Plenum of the Supreme Court of the Russian Federation, including using the norms of foreign legislation.
The Institute of Prosecutor’s Participation in Administrative Matters in Courts: From the Imperial Period to the Present
Authors: Levskiy V. K.
Published: December 2020

The paper describes the main historical periods of the development of the institution of the participation of the prosecutor in administrative cases in courts. From the historical analysis of the powers of the prosecutor, the author concludes that the administrative proceedings, in which the prosecutor took an active part, have always existed, but took different forms. An analysis of the legislation and opinions of scientists of the Russian Empire period in comparison with modern legislation and legal concepts allows us to highlight the best from the past and move it to the modern legal field. The powers of the prosecutor in administrative proceedings currently include the provisions of the legislation of the Russian Empire and the Soviet period, however, they require additional reflection based on historical experience. As a result, the author concludes that, without taking into account the historical past in terms of the institution of the participation of the prosecutor in administrative cases in courts, it is currently impossible to develop and improve the powers of prosecutors in administrative courts.
Review of the Monograph by S. S. Burynin, S. V. Valov, Yu. A. Tsvetkov, T. V. Cheremisina "Appointment of Citizens and Consideration of Applications in Investigative Bodies". Moscow: Moscow Academy of the Investigative Committee of Russia, 2020.
Authors: Savoskin A. V.
Published: December 2020

The paper presents a detailed analysis of the book "Appointment of Citizens and Consideration of Applications in Investigative Bodies". The emphasis is placed on such issues raised in the book as the interpretation of the term "citizens’ application", the system of legislation on citizens’ applications, the system of citizens’ applications and the system of their consideration. Special attention is given to the right of the heads of the Investigative Committee of the Russian Federation, the Ministry of Internal Affairs of the Russian Federation and the Federal Security Service of the Russian Federation to regulate issues related to citizens’ applications; differentiation of citizens’ applications based on the basic interest of the applicant; functional subsystem for considering citizens’ applications; the passage of time when considering citizens’ applications; termination of correspondence (including the priority of the legal fact of receipt of the application to the final addressee, and not the legal fact of filing an application); the rules for organizing a personal reception (including psychological advice) and the analysis of judicial practice. The following things are being criticized in the review: author’s definition of the category "citizen application"; classifying the right to apply as political; referring requests of authorities and their officials to the number of applications; redundancy of the approach to respond to electronic appeals. It is proposed to continue research in terms of establishing the concept and characteristics of an organization performing public functions (as a recipient of citizens’ applications); improving the departmental procedure for registering applications and reports of crimes; improvement of legislation on electronic and collective applications.

The new coronavirus infection severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the natural epidemic rise of respiratory infections can occur in combination with them. This report aimed to answer the question that arises regarding features of clinical and laboratory diagnostic characteristics of mixed infections. A group of patients was analyzed with combined course of acute coronavirus infection SARS-CoV-2 and influenza using clinical and laboratory instrumental data. Attention is drawn to the fact that combined course of these nosologies, characterized by a significant decrease in blood oxygen saturation with atmospheric air breathing and moderately pronounced changes of the chest organs according to computed tomography results goes together with a moderate course of the disease. Absolute lymphopenia and high C-reactive protein and fibrinogen levels may be specific markers that confirm viral etiology of this disease. At the same time, high titer of antibodies to SARS-CoV-2 did not always correspond to the full elimination of coronavirus from the body in patients with mixed infection.

Published: December 2020

In this paper, the approaches to optimizing the environmental management system at pharmaceutical manufacturing enterprises and the environmental policy of pharmaceutical corporations in general were proposed. In the course of the study, it has turned out that the indicators of the negative impact on the environment as a result of the economic activities of industrial pharmaceutical enterprises do not take into account all the specific features of technological processes. At modern pharmaceutical enterprises, direct environmental risks are minimized at working areas and, in fact, their assessment is replaced by the calculation of barrier and isolation measures, which is in the competence of calculating sanitary and epidemiological risks only for employees of enterprises. In the course of pre-design, design work and the creation of pharmaceutical manufacturing enterprises, owing to the requirements and mandatory application of GxP, in fact, the negative impact on the environment at the enterprise itself within the boundaries of its sanitary zone is reduced to zero. However, a number of questions remain to be resolved, including how and to what extent a pharmaceutical business entity, in the course of its activities, causes a negative impact on the environment outside its location.
With this article, we begin series of publications of the results of our research in the direction of multilateral analysis of environmental risks in pharmaceutical organizations of different profiles and groups of pharmaceutical companies, united into separate corporate companies.
Compared to those approaches to assessing environmental risks as a result of the activities of pharmaceutical manufacturing enterprises, which are mainly focused on meeting the GxP requirements and relate to the quality of manufactured pharmaceutical products, we propose to take into account information with an emphasis, inter alia, on the energy saving policy of the Russian pharmaceutical industry.
The main goal of an integrated approach to the development of environmental policy and environmental management system in the pharmaceutical industry is for the management of manufacturing enterprises to comprehensively monitor and assess all environmental risks and energy conservation, in particular, taking into account the provision of energy efficiency to reduce the negative impact on the environment.
Event Location with Sparse Data: When Probabilistic Global Search is Important
Authors: Arrowsmith Stephen , Park Junghyun , Che Il-Young , Stump Brian , Averbuch Gil
Published: December 2020

Locating events with sparse observations is a challenge for which conventional seismic location techniques are not well suited. In particular, Geiger’s method and its variants do not properly capture the full uncertainty in model parameter estimates, which is characterized by the probability density function (PDF). For sparse observations, we show that this PDF can deviate significantly from the ellipsoidal form assumed in conventional methods. Furthermore, we show how combining arrival time and direction-of-arrival constraints—as can be measured by three-component polarization or array methods—can significantly improve the precision, and in some cases reduce bias, in location solutions. This article explores these issues using various types of synthetic and real data (including single-component seismic, three-component seismic, and infrasound).

Authors:   Company «WCIOM», Glotova A.O. ,   Russian State Social University
Published: December 2020

in modern society, the problem of the influence of cinema on the viewer and its value-semantic sphere is of great importance. It is worth noting that this area of influence on a person, despite the relevance due to the popularity of this type of product, is poorly studied from the point of view of sociology. During the work, the cultural identification of society through cinematographic art was analyzed, as well as the relationship between the viewer and the movie character. Theoretical approaches to studying the influence of cinema on a person of both foreign and domestic scientists are considered. The analysis allows concluding that the impressions that the viewer receives while watching the film can reach the level of real life impressions and is transferred to the experience of his daily life. Consequently, the products of cinematographic art not only affect the person, but also constitutional various aspects of his everyday reality.

Öğretmenlerin Örgütsel Sessizlik Davranışları ve Örgütsel Özdeşleşmeleri Arasındaki İlişki
Authors: ATMACA Taner
Published: December 2020

Bu çalışmanın temel amacı çeşitli kademelerde görev yapan öğretmenlerin örgütsel sessizlik ve örgütsel özdeşleşme düzeyleri arasındaki ilişkinin incelenmesidir. Bunun yanında örgütsel sessizlik ve örgütsel özdeşleşme arasındaki ilişkinin yönünü ve düzeyini belirleyebilmektedir. Bu bağlamda Düzce ilinde görevli toplamda 660 öğretmenden Örgütsel Sessizlik ve Örgütsel Özdeşleşme ölçekleri ile veriler toplanmıştır ve araştırma ilişkisel tarama yöntemine uygun olarak tasarlanmıştır. Yapılan Mann Whitney-U-testi ve Kruskal Wallis-H testi analizi sonuçlarına göre öğretmenlerin örgütsel sessizlik ve özdeşleşme düzeyleri ile çalıştıkları okul türü, yönetici ile aynı sendikadan olma ve çalışılan okul kademesine göre istatistiksel olarak anlamlı fark tespit edilmiştir. Öğretmenlerin cinsiyeti, kadro türleri (kadrolu-sözleşmeli-ücretli), kıdemlerine göre her iki değişken açısından istatistiksel olarak anlamlı fark yoktur. Özel okullardaki örgütsel sessizlik düzeyi devlet okullarından anlamlı şekilde daha yüksek olarak tespit edilmiştir. Bununla beraber okul kademeleri arasında da anlamlı farklılık söz konusudur ve örgütsel sessizliğin en yüksek düzeyde lise kademesinde, en az düzeyde ise ilkokul kademesinde olduğu görülmektedir. Örgütsel özdeşleşme düzeyleri de kademeler arasında anlamlı farklılık göstermektedir. Örgütsel özdeşleşme en yüksek ilkokul kademesinde daha sonra ortaokul kademesinde iken en az düzeyde ise lise kademesinde görülmektedir. Örgütsel sessizlik ile örgütsel özdeşleşme arasında negatif, düşük düzeyde ve anlamlı korelasyon vardır. Öğretmenlerin örgütsel sessizlik düzeyi arttıkça özdeşleşme düzeyleri düşmektedir. Okullarda katılımcı yönetim anlayışını yerleştirecek, her öğretmenin okulun değerli bir üyesi olduğu düşüncesini oluşturacak yönetsel uygulamalara daha çok yer verilmesi önemli görülmektedir.
MATHEMATICAL MODELLING, SIMULATION ANALYSIS OF A PHOTOVOLTAIC THERMAL SYSTEM
Authors: HAJİBEİGY Mohammad Taghi , WALVEKAR Rashmi , CV Aravind
Published: December 2020

Solar energy is one of the cleanest, environmentally friendly and abandoned available energy sources.
While the photovoltaic (PV) module converts this free and available energy in the form of electrical energy, the
efficiency of the PV module reduces as the temperature of the PV module rises above nominal value. The
Photovoltaic Thermal (PVT) system removes the wasted thermal energy from the surface of the PV which is caused
by the reflection of the sun's irradiance and stores it for the useful application, hence, maintain the electrical
efficiency of the PV module. This paper analyses the heat response data collected from a PVT system, under
normal conditions, with steady water acting as a coolant. Experimental and simulation values were compared and
analyzed in this paper. The thermal response of the PVT system depends solely on the irradiation of sunlight.
Therefore, the thermal energy output of the PVT system varies according to the solar irradiation. In this experiment,
the PVT thermal response was measured via Thermocouple sensors mounted in each layer of the PVT system,
which included solar panel, aluminum thermal plate, and heatsinks. A charge controller was connected to the output
of the PV to regulate the charging process for a battery so that the electrical output can also be affected by the
thermal response of the solar panel. The amount of solar irradiation was calculated based on the reading from the
Pyranometer and the surface area of the PV. The setting of the Pyranometer and the thermocouples to measure the
PV thermal value and the ambient temperature was set to ten seconds each, which was read using a data logger.
The entire experiment is conducted in a constant condition such as constant ambient temperature and pressure to
obtain fair data. Understanding the thermal transfer between each layer of the PVT system will help to increase
the efficiency of the electrical and thermal output, from the study it was known that faster heat transfer maintains
a steady temperature, this paper helps to design a PVT system with a better efficiency under a non-optimal
condition.

In this paper research was expanded on waste that can be recycled. There are so many different types of waste products available in our country that would ruin the environment. Three different products are considered to reduce some of the problems among them two are fibers and the other is polyethylene. Chicken feather rachis and Neem sawdust are the two different fibers and the reinforced material is high density polyethylene (HDPE). These materials are made as seven different compositions to find the ability of the sample in different characterizations. The seven compositions are 80H-10CF-10SD, 80H-5CF-15SD, 80H-15CF-5SD, 80H-20CF, 70H-30CF, 70H-30SD, 80H-20SD, and these compositions are made in CIPET, Hyderabad by using single screw extruder& strand pelletizer. These granules are prepared with the help of Injection moulding, the samples are examined by various testing to prove the ability, strength, structure of materials in individual, and combination forms. The testing conducted for the samples is that the Morphology of the sample was characterized using FESEM, XRD. It is examined that the ratios are light weight with high strength by using the testings and it gives perfect images without any cracks on the surface and no more defects among these ratios.

The application range in defense, aerospace and automotive sectors have enabled aluminium metal matrix composites to emerge in different technological fields due to enhanced micro structural and mechanical characteristics. In the present study, friction stir processing is used to fabricate Al2024/SiC composite with one, two and three passes of the cylindrical tool. Optical microscopy and scanning electronic microscope (SEM) were used to validate the processed sample and to justify the morphological aspects. Energy dispersive spectroscopy (EDS) analysis has also performed to confirm the presence of SiC particles in the composite. It also includes the analysis of mechanical properties such as tensile strength, Rockwell hardness test and nanoindentation to characterize the prepared samples. Improvement in tensile strength with a maximum of 443 MPa, the hardness of 121 HRB and nanoindentation of the specimen was depicted through the mechanical tests.

Composite materials are very widely used in the manufacturing of structures because of their specific mechanical properties. However, they are characterized by heterogeneity and anisotropy and they present great challenges in designing and also in predicting their behavior by using the numerical simulation. The unidirectional composite material has a more relevant property which is the transverse elasticity modulus E2. The determination of E2 is still interesting researchers because of the diversity of results obtained by several models and approaches. This study aims to predict the transverse elasticity modulus E2 of a unidirectional Glass/Epoxy composite material, the effect of the arrangement fibers on the transverse elasticity modulus and predict the values of the reinforcement factor used in the Halpin-Tsai model. To do so first we adopted the micromechanical approach, which is accurate but requires much computing, and we used a calculation code based on FEM method and considered two parameters to vary, which are the volume fraction of fibers and the distribution of fibers. The obtained results of numerical modeling were tightly compared to those obtained by the available analytical models and the adopted approach can be used to predict the transverse elasticity modulus E2 and the reinforcement factor ξ.

Metal matrix composite Al2O3 particle reinforced Al have become useful engineering materials due to their properties such as low cost, wear-resistant, heat-resistant and low weight. The present study focused on prediction of temperature produced during machining of Al2O3 reinforced with Al7075. In this investigation the percentage of Al2O3 (mesh size of 100-300)was varied 1%, 3%, 5%, 7% and 9% to the base material of Al7075. The temperature was measured using thermal gun at machining tip of the tool at which maximum temperature were measured by varying operational parameters such as depth of cut (0.25, 0.5, 0.75, 1 and 1.25mm), spindle speed (80, 112, 140, 200 and 355rpm) and feed rate (0.10, 0.12, 0.16, 0.2 and 0.25mm/sec). Experimental results revels that the temperature increases with increase in feed rate and depth, whereas, in case of spindle speed there is a fluctuation in temperature for all the combinations considered. The percentage contribution of operational parameters on temperature was determined using ANOVA analysis. Overall analyses for all the combination considered shows that feed rate (45.07%), depth (33.75%) and spindle speed (5.2%) on temperature. The developed models with a P-value are less than 0.05 were considered to be a statistically significant with 95% of confidence interval. A good agreement between experimental and statistical modeling were achieved and comparison of experimental and statistical analysis were drawn.
Argumentation of filter width selection with the use of envelope spectrum in vibration diagnostics of rotary machine defects
Authors: Sundukov A. E.
Published: December 2020

The paper shows certain ambiguity of the narrow-band boundary of random processes obtained by different authors. The use of filters of different widths in obtaining the envelope spectrum makes it difficult to compare the obtained results by estimating the depth of amplitude modulation in vibration diagnostics of defects in rotary machines. We studied the results of bandpass filtering of the noise process only, as well as of amplitude-modulated noise. The analysis of the results of filtering of a broadband normal random process with constant spectral density and the representation of the spectrum width of the resulting oscillations through spectral moments showed that processes selected by a filter of no more than 1/3 octave bandwidth should be considered narrowband. Simulation of the amplitude of a broadband noise by the harmonic process and estimating the dependence of the modulating harmonic amplitude, the depth of amplitude modulation, skewness and kurtosis, as well as envelope characteristics on the width of the selecting filter allowed us to establish that a relative filter width of 30% should be applied when the envelope spectrum is used.

Published: December 2020

The paper discusses the issues of designing a control moment gyroscope electric drive with strict requirements in terms of the accuracy of ensuring a given rotation rate of the gyro motor suspension. A brief description of the control moment gyroscope electric drive applied currently is presented and the issues of improving the electric drive characteristics are discussed. As a solution, an electric drive is proposed which operates in the mode of feedback loop using angle sensors located on the axes of the gyroscope suspension and the engine rotor. The paper describes the arrangement of the control moment gyroscopes on advanced spacecraft for Earth remote sensing and presents the analytic expressions needed to calculate the control moments that affect the spacecraft. The moments are in the projection to the coordinate system brought into coincidence with the spacecraft. The paper compares spacecraft angular velocity stabilization errors for the cases of using the conventional scheme of control moment gyroscope electric drive and the newly developed one. The presented results can be used for developing control moment gyroscope electric drives to be mounted on spacecraft of different purpose with strict requirements on ensuring operation at specified rotational velocities.
