The Central and State Governmenthave implemented several tribal development schemes throughout the country for the welfare of the tribes. But, whether the tribes have felt the real benefits of these schemes is a big question. It can be measured by analyzing the attitude of tribes towards tribal development schemes. In this context, a survey was conducted among the tribes of Jawadhu hills and Kalrayan hills, representing three districts: Salem, Tiruvannamalai, and Viluppuram. From the study, it was found that 35.19 per cent of the tribal respondents had a highly favorable attitude, followed by 33.33 per cent with a less favorable attitude and 31.48 per cent of tribal respondents with a moderately favorable attitude towards tribal development schemes. The possible reason for the findings and the suggestions to improvethe attitude of scheduled tribes in favour of the tribal development schemes described.

In Tamil Nadu, groundnut is an essentialand major oilseed crop, mainly grown under rainfed conditions. The changes in weather parameters might affect the productivity of groundnut. Hence, crop yield forecasting based on weather parameters is essential for proper planning, decision-making, and buffer stocking policy formulation. As for the data with multicollinearity, penalized regression models i.e.Ridge, Least Absolute Selection and Shrinkage Operator (LASSO) and Elastic Net (ENet), are better alternatives to classical linear regression. The data on weather parameters such as maximum temperature(Tmax), minimum temperature (Tmin), morning relative humidity (RH I), evening relative humidity (RH II), and rainfall were collected for 29 years from1991-2019. The weather indices approach was used in this study. The collected data were partitioned into training, and testing datasets and the hyperparameters of penalized regression models were tuned using cross-validation. The performance of the models wasevaluated using an adjusted coefficient of determination (R2adj), Root Mean Squared Error (RMSE), normalized RMSE (nRMSE), Mean Absolute Error (MAE) and Mean Absolute Percentage Error (MAPE) as the goodness of fit criteria. The results revealed that all the Penalized regression models provide a better fit to data. The SMLR and ENet were found to predict with better accuracy. Hence, these methods can be used for groundnut yield forecasting during Kharif season for the Coimbatore district of Tamil Nadu.

Comparison of trace element contents in normal thyroid and thyroid with Hashimoto's thyroiditis using neutron activation analysis
Authors: Vladimir Zaichick
Published: November 2021

Role of trace elements (TE) in etiology and pathogenesis of Hashimoto's thyroiditis (HT) is unclear. The aim of this exploratory study was to assess whether there were significant changes in thyroid tissue levels of ten TE (Ag, Co, Cr, Fe, Hg, Rb, Sb, Sc, Se, and Zn) are present in the autoimmune transformed thyroid. Ten TE of thyroid tissue were determined in 8 patients with HT and 105 healthy populations. The measurements were performed using non-destructive instrumental neutron activation analysis with high resolution spectrometry of long-lived radionuclides. Elevated mean values of Ag, Hg, and Rb content were found in thyroid with HT in comparison with normal level (in approximately 21, 30, and 1.6 times, respectively). Because the considerable changes in some TE contents in tissue of thyroid with HT were found, it is reasonable to assume that the levels of these TE in thyroid tissue can be used as HT markers. However, this topic needs additional studies.

Training issues of restoration specialists of real estate consideration is an important area of architectural higher education due to the need to replenish personnel for the development of scientific-, design- and professional activity spheres. The interdependence of the spheres of science, practice and education is a necessary condition for the preservation of cultural heritage, which currently exists as one of the important indicators of the state's cultural policy. The problem of mastering the architectural and urban planning heritage consists in the need to consider two opposing tendencies: the protection of the primary uniqueness of an architectural monument and the development of a historical urban environment with the involvement of modern architecture techniques, as a result of which historical authenticity is gradually lost and the urban environment is acquiring an increasingly universal and international character. In contemporary architectural design this problem is solved at the stage of developing urban planning documentation and detailed plans for the territory of historical areas, considering the system of restrictions on architectural and urban planning activities in the protection zones of cultural heritage objects of different use modes. The educational programs of the KhNUCEA Department of Reconstruction and Restoration of Architectural Objects have been developed considering professional competencies, aimed at mastering the world experience of achievements in the field of architectural and restoration education while maintaining the traditions that have developed over the years of the architectural education existence in Kharkov. The Department of Reconstruction and Restoration of Architectural Objects, formed in 1996, has united in its team specialists with experience in scientific and practical activities in the areas of urban planning restoration, restoration of architectural monuments, architectural archeology, reconstruction of historical objects.

Authors: Chybisova N.
Published: November 2021

The article deals with new principles and organizational forms of social work in the context of digital society development. The author attributes the necessity to implement changes in the sphere to a higher level of individualism in the modern society and young people’s urge to self-fulfillment and self-realization. The paper reviews most common existing forms of students’ public organizations: parliaments, councils, unions and clubs. The author highlights that nowadays they tend to perform the advisory function in education institutions, or their activity is limited to actually being social clubs for interest groups. Frequently, they are not designed to handle strategic tasks education institutions and students communities are facing.

Following the guidelines the new Ukrainian Law on Higher Education puts forward, the author addresses the experience of Kharkiv University of Humanities “People’s Ukrainian Academy” in organizing pupils’ and students’ self-governance, and the practice of its public organizations. The author attempts to analyze how effective the current system is, whether its organizational principles and forms are up-to-date, to what extent they meet students’ needs and expectations. The author shares PUA’s experience in the work on training and educating youth leaders, explicates how naturally they make up constituent part of the university education and pedagogical system, how successfully they cooperate with other teachers’ and pupils’ public organizations of the complex of continuous education. A very special attention the article pays to the PUA pupils’ organization “ISTOK” and its activities.

According to the author, the secret of public organizations’ successful performance lies in team work and cooperation, collective problem-solving, integration of experience and up-to-date approaches to social work.

Problem statement. The problem of influence of capillary-porous structure, characterized by the presence of a spatial lattice of micropores, capillaries and various defects on the strength and stability of concrete polymer, is considered. Purpose of the article. Estimation of porosity determination methods (total volume and size distribution of pores) as a structural characteristic of concrete polymer components, aggregates and fillers. Conclusion. The drop in strength of furan compositions is mainly determined by the pore formation as a result of the accumulated wetted aggregates from the particles of the dispersed filler. The results of the experiments show that with increasing the dispersion of the filler there is a decrease in the volume of the binder under the condition of constant ratio p / n, which is explained by the increase in pore formation, which is increased due to lack of polymer and the manifestation of the effect of air trapping. The complete impregnation of the mineral components creates a polymer distribution over the entire volume and forms a continuous and evenly distributed lattice of the polymer and its porous space. Accordingly, the polymer concrete is compacted and contact is formed between the matrix and the polymer.

Despite having remarkable features such as low density, ease of fabrication and recyclability, linear low-density polyethylene (LLDPE) has several drawbacks like poor stiffness and low creep resistance which fortunately can be improved by incorporating with other suitable nanofillers. In this study, graphene nanoplatelets (GNPs) that are well-known for its high surface area and superior stability were selected to reinforce the polymer network of LLDPE via melt blending. During mixing processing, the rotor speed, mixing temperature and mixing time parameters are manipulated with the aids of 5-level-3-factor central composite rotatable design (CCRD) in order to determine the optimization of processing parameters in preparing LLDPE/GNPs nanocomposites. The experimental data is fitted with the statistically significant quadratic model with R2 value of 0.8601. The results showed that the tensile strength of LLDPE/GNPs nanocomposites could be extended to 24.80 MPa. The optimum processing parameters for preparation of LLDPE/GNPs nanocomposites were found to be at 101 rpm rotor speed, 139.8oC of mixing temperature and 13.2 min of mixing time, resulting in LLDPE/GNPs nanocomposites with tensile strength of 24.11 MPa. Conclusively, our study has provided a novel statistical design of experiment to obtain the optimum processing parameters in preparing LLDPE/GNPs nanocomposites.

The experimental investigations of annular flow were conducted in horizontal pipe using water/air in a 0.0504m internal diameter pipe loop with a total length of 28.68m. To understand annular flow behaviors, conductivity ring sensors, conductance probe sensors and Olympia high speed digital camera were used. In all the experiments, emphasis were on annular flow behavior, phase distribution and liquid film thickness. Liquid film thickness was observed to be thicker mostly when the superficial gas velocities were within 8.2699 m/s to 12.0675 m/s. Above the aforementioned superficial gas velocities, the flow became uniformly distributed on the walls of the internal pipe diameter hence reducing the thicker liquid film at the bottom with gas core at the center of the pipe. More so, annular-slug flow was discovered in the investigation. At superficial liquid velocity of 0.0505 m/s-0.1355 m/s on superficial gas velocities of 8.2699 m/s – 12.0675 m/s, annular-slug flow was prominent. Also discovered was at superficial liquid velocities of 0.0903 m/s - 0.1355 m/s with respect to superficial gas velocities of 13.1692 m/s – 23.4575 m/s, the pipe walls are fully covered with liquid film at very high speed at the entire walls (upper walls and bottom). Also discovered in this experiment is the wavy flow of the upper walls. The liquid film thickness that flows at the upper pipe walls, creeps in a wavy flow. Therefore, the entire flow behavior in an annular flow could be grouped into; wavy-flow at the upper walls, annular-slug flow and thicker liquid film at the bottom with gas core at the center.

Heart failure means that the heart is not pumping well as normal as it should be. A congestive heart failure is a form of heart failure that involves seeking timely medical care, although the two terms are sometimes used interchangeably. Heart failure happens when the heart muscle does not pump blood as well as it can, often referred to as congestive heart failure. Some disorders, such as heart's narrowed arteries (coronary artery disease) or high blood pressure, eventually make the heart too weak or rigid to fill and pump effectively. Early detection of heart failure by using data mining techniques has gained popularity among researchers. This research uses some classification techniques for heart failure classification from medical data. This research analyzed the performance of some classification algorithms, namely Support Vector Machine (SVM), Decision Forest (DF), and Boosted Decision Tree (BDT), to classify accurately heart failure risk data as input. The best algorithm among the three is discovered for heart failure classification at the end of this research.

In order to indicate similarities and differences, and to achieve the objectives of the research and to verify the hypothesis, a SWOT analysis was performed. A number of safety issues in astrotourism are still unregulated. Among modern countries preferring to maintain a monopoly in space, authoritarian countries dominate, such as Russia, where every sector of space exploration, including space tourism, depends on the state. In democratic countries, private entities are largely the partners or service providers of the states. In the near future, private entities will set the direction of space tourism development. States will abandon their monopoly on regulatory and organizational powers in space exploration. However, for reasons of their own security and safety interests, they will leave themselves in control of this sector. The latter will lead to the development of public-private partnerships.

Introduction-the perception of tourists is a crucial way to reflect the quality of infrastructure in the World Heritage Sites (WHSs), which would be continually developed to remain the tourism demand and to sustain the WHSs themselves. Aims-the research aims to study the perceptions of foreign tourists pertaining to the infrastructure in the World Heritage Historic Town of Sukhothai, Thailand. Method-this empirical qualitative research uses the structural interview form as a research tool for face-to-face interviews with 41 foreign tourists using purposive sampling. Results and interpretation-the findings show that the access and ease of walkways were the key infrastructure issue that was unpopular amongst tourists; and others crucial factors were unfolded. Tourists from different demographics contributed to the same perceptions, thus indicating a critical issue for the development of this tourist destination.

With the goal of informing federal and state policy makers in a time of budget constraints, we used a systematic review methodology to identify and summarize findings from studies that examined the effects of losing grant aid due to policy changes and students’ failure to meet renewal requirements. Studies reviewed in this policy brief show negative effects on student outcomes when grant aid is reduced or eliminated. While results vary, this general conclusion applies when grant aid is reduced or eliminated from programs that differ in scope (federal and state), eligibility requirements (merit and need), and award amounts. This brief illuminates the importance of maintaining grant aid funding for college student enrollment, persistence, achievement, and completion. Especially in context of other pandemic-related stressors, reducing need-based grant aid will likely exacerbate declines in college enrollment, progression through college, and degree completion for vulnerable students.

Published: November 2021

The subject of the paper is the assessment of regional debt sustainability in accordance to the Budget Code of the Russian Federation. The relevance of the study is due to the aggravation of the regional debt problems at the end of 2020 and the need to have an assessment system that allows to timely respond to a decrease in the level of regional debt sustainability. The novelty of the study consists in the analysis of the system of debt sustainability indicators and their threshold values using the methods of cluster analysis. The article aims to examine if the current assessment system allows to classify regions by the level of debt sustainability quite clearly. As a result of the study, it was shown that the used debt sustainability indicators partially duplicate each other, and the methods of their calculation and the established threshold values discriminate against subsidized regions. In addition, it was shown that the grouping of regions based on the current assessment system does clearly distinguish between regions with high and medium levels of debt sustainability. The conclusion of the study is that in order to improve the system for assessing debt sustainability, it is necessary to change the set of debt sustainability indicators and the procedure for calculating them, as well as to set appropriate new threshold values for the new set of indicators. The prospect of the study is to conduct a similar analysis based on data for 2020 and refine new thresholds for debt sustainability indicators.

The relevance of the research topic is determined by the need to respond to increased climate risks, which makes countries develop climate policies that can effectively meet sustainable development challenges and protect national economic interests. The transformation of climate policy causes the need to shift capital flows from “brown” economy sectors to “green” ones and integrate environmental factors into the process of making financial and investment decisions. At present, the EU is actively developing a climate finance system which will have an impact on the Russian economy. The article is aimed at outlining the changes in climate policies and financial strategies in the EU and Russia, influenced by the global climate agenda. It analyses the volumes and sources of climate finance mobilized by the EU, as well as regional support instruments in the transition period. The article determines the current changes in the Russian Federation’s climate policy. As a result of the research, the authors have come to the following conclusions. The EU is a vivid example of the fact that countries have long moved from climate change debates to the implementation of specific measures. The Russian Federation lags far behind the EU in terms of both mobilizing financial resources to ensure the transition to a low-carbon economy, and developing proven emission control instruments which help to stimulate the reduction of greenhouse gas emissions and fulfill the obligations under the Paris Agreement.

Published: November 2021

The article analyzes the experience of legislative regulation of financial statement preparation by micro entities in the Commonwealth of Independent States, the European Union, and the United Kingdom. The legislative acts of the countries, national accounting standards and financial reporting standards serve as the methodological basis for the analysis. For the purpose of this study the article identifies the criteria for categorizing an organization as a micro entity, analyzes the documents regulating the procedure for the preparation of financial statements, and compares the procedures for financial reports formation by micro entities in different countries. Micro entities are an important component of the country’s economy, affecting the level of employment, gross domestic product and other important indicators of the country’s development. In Russia, micro entities account for 96 percent of the small and medium-sized business sector, whose share in the gross domestic product was about 20.6 % in 2019 according to Federal State Statistics Service estimates and which created about 33 % of jobs. For comparison, in the OECD countries small and medium-sized businesses generate, on average, about 55 % of GDP and about 59.1 % of jobs, whereas in the EU countries the percentage is higher: 57.5 % of GDP, and 65 % of the employed. However, in order to support the development of micro entities, it is necessary to create favorable conditions for the implementation of entrepreneurial activities, in particular through simplifying the procedure for the formation and submission of financial statements.
