Economic and geographical and socio-economic differences of regions of the Republic of Belarus as a basis for improvement of administrative-territorial division
Authors: Antipova Ekaterina A. , Shavel Aleksej N. , Zaprudskij Ilja I.
Published: June 2019

The article is devoted to the analysis of economic-geographical and socio-economic differences of the regions of the Republic of Belarus in order to improve the administrative and territorial division (ATD). The decisive role of the Belarusian scientific school of economic geography in developing of the principles of the ATD of Belarus at various periods of development is shown. The historical stages of formation, advantages and disadvantages of the current system of the ATD of the Republic of Belarus are revealed. The positive and negative international experience of conducting of administrative and territorial transformations is systematized. The significant disproportions in the resource, demographic and economic potential of the regions of Belarus and their various contributions to the social and economic development of the state are determined. Based on the centro-peripheral principle, a scheme of the regions of Belarus by the level of socio-economic development has been developed, which indicates significant changes in the development of regional economic complexes that have occurred over the past decades. About 20 % administrative districts are characterized by the properties of the center or semi-center, which have the ability to perform the functions of regional centers in the new ATD. More than 30 % administrative areas are peripheral in terms of socio-economic development. The obtained results are the basis to the need to improve the ATD of the Republic of Belarus.
The influence of thermal conditions on potato yield in the administrative regions of the Republic of Belarus
Authors: Davydenko Olga V. , Lopukh Piotr S.
Published: June 2019

The analysis of the dynamics of thermal conditions during 1961–1988 and 1989–2015, as well as the adjacent decade of the study period. Changes were estimated for the average temperatures of individual months of the year, high average and maximum daily temperatures, as well as for the duration of the active vegetation period and the sums of active temperatures. The established increase in average annual temperatures was 0.4 °С per decade. At the same time, in the first half of potato vegetation (May – June) the thermal trends are ambiguous, while in the second half (July – August) the increase of average air temperatures prevails. The increase in temperatures in the summer months is accompanied by an increase in the prevalence of negative thermal effects on potato yields, which is confirmed by negative correlation coefficients of potato yield deviations from trend lines and indicators such as the air temperature in July and the number of hot days (with an average temperature above 20 °С and a maximum temperature above 30 °С). Statistical reliability of correlation between potato yield deviations from trend lines and July temperatures is confirmed only in 1989 –2015 and covers 60 administrative districts. In these and most of the remaining areas, the correlation coefficients are negative. It is established that the proposed and justified critical value of the number of days with a maximum temperature above 30 °С (10 and more) determines more than a third of the negative deviations of potato yield in most of the country, and the probability of its negative impact in the modern period is 70 %. The decrease in average yield is 12.7 c/ha (8 %). It was found that the most unfavorable hot period occurs during the tuber formation and growth of potato tubers, in connection with which possible measures of adaptation of potatoes to temperature increase are proposed: the use of heat-resistant potato varieties, the shift of potato planting dates to earlier dates, irrigation (in the case of a combination of high temperatures with insufficient moisture).

On the basis of the features of the landscape organization of the mountainous territory and the properties of the integral geomapplexes of Chornohora, on the example of the key-site Sheshul – Petros, as well as regularities of the distribution of negative natural processes, the main centers and scale of the influence of the pasturage objects on the specific natural territorial complexes of the level of the tract were determined. On the landscape basis there are conditionally distinguished highland natural complexes from artificially developed pasture lands of forest middle level tier. The largest field pasturing type in the vicinity of the key area of Sheshul – Petros, the features of their placement and functioning, as well as the extent of attracting highland tracts, which are also used in the economy as pasture land in our research. The analysis of the morphological structure of the highlands made it possible to establish regularities of the organization of natural complexes, which express the properties and ecological state of the polonina pasture lands, and to develop recommendations for optimization of the pasturage as the main land useage of the highlands of Chornohora.
The Role of Hormones in the Regulation of Glycogen Metabolism in the Clawed Toad Xenopus Laevis (Daudin)
Authors: Atar-Zwillenberg Daphna , Atar Michael , Morson Gianni , Spornitz Udo
Published: June 2019

The hormonal regulation of amphibian glycogen metabolism was studied in Xenopus laevis as a typical member of the anurans (tailless amphibians).The main focus of this study was given to the effects of various hormones on the glycogen/glucose balance in adult toads. We determined biochemically the liver and muscle glycogen contents as well as the blood glucose and lipid levels for a number of hormones and also diabetes inducing substances. Additionally, we examined ultrastructure changes in hepatocytes induced by the various treatments, and also investigated the activity of carbohydrate-relevant enzymes by histochemistry. With one exception, the liver glycogen content of Xenopus remained basically unchanged by the treatments or was even slightly enhanced. Only human chorionic gonadotropin, through which the vitellogenic response is triggered, prompts a significant decrease of liver glycogen in females. Under the same conditions the male liver glycogen content remained stable. Muscle glycogen contents were not affected by any of the treatments. Blood glucose and lipid levels on the other hand were elevated considerably in both sexes after application of either epinephrine or cortisol. The ultrastructural examination revealed a proliferation of Rough Endoplasmic Reticulum (RER) in hepatocytes from epinephrine treated toads of both sexes as well as from HCG treated females. By histochemistry, we detected an elevated glucose-6-phosphatase activity in the hepatocytes from toads treated with either epinephrine or cortisol. These treatments also led to enhanced glycogen phosphorylase activity in males, and to a slightly elevated glyceraldehyde-3-phosphate dehydrogenase activity in females. Our results show that the hepatic glycogen is extremely stable in adult Xenopus. Only vitellogenesis causes a marked utilization of glycogen. Since the blood glucose levels are elevated in epinephrine or cortisol treated toads without the liver glycogen being affected, we conclude that either protein and/or lipid metabolism are involved in carbohydrate metabolism in Xenopus laevis.

Tatar Language Teaching in the Republic of Mordovia: Potential, Problems, Perspectives.
Authors: Martynenko Alexander V.
Published: June 2019

The article analyses the development of the Tatar national school, including Tatar language teaching, in Soviet and Post-Soviet Mordovia. In the introductory part of the article it is explained that in the Middle Ages and the subsequent Imperial period of national history, the formation of Tatars (including on the territory of modern Mordovia) was mainly confessional, Muslim. This education was concentrated in schools of two levels - mektebah and madrasah, and was based on the Hanafi Math'hab (law school) of Sunni Islam. Further, it is concluded that in the first decades of the Soviet period the new, secular, system of national education of the Tatars developed, replacing the traditional religious (Muslim) school. The article provides an overview of formation of the Tatar national school in the Mordovian Autonomous Soviet Socialist Republic and its preservation in the Republic of Mordovia. The Soviet school system of education provided a fairly rapid increase in the literacy of the Tatars of Mordovia already in the late 1920s  – 1930s, within the framework of the national school as well. As for the modern period, the special role of teaching Tatar is emphasized not only by the state authorities of the Republic of Mordovia, but also by the Regional National Cultural Autonomy of the Tatars “Yaktashlar” and by representatives of the state and public structures of Tatarstan. The article concludes that the system of Tatar national schools in Mordovia that developed during the Soviet period has adapted to new sociocultural and ethno-political Post-Soviet realities, and Tatar language teaching has not only been preserved there in the 1990s - 2010s, but continues to function effectively and to develop.
Ways of adaptation of the peoples of the North to the new economic and social realities of the mid-1980s – late 1990s (based on field research in the Koryak Autonomous district)
Authors: Batyanova Elena P. , Murashko Olga A.
Published: June 2019

The article analyzes the processes of adaptation of the indigenous peoples of the North, living in the Koryak Autonomous district, to economic and social changes and shocks of the mid-1980s – late 1990s. There was a surge of national consciousness of indigenous peoples during the period of perestroika, which led to creation of associations, unions. This, in turn, caused the processes of revival of their ethnic cultures: language, traditional customs, rituals, folklore. Economic and spiritual crisis associated with the collapse of the Soviet system manifested itself in the collapse of the most important economic sectors of indigenous peoples – reindeer husbandry and fishing, in a sharp drop in living standards, increasing morbidity and mortality, reducing the population. The article analyses ways to overcome the economic and spiritual crisis, including active legislative activity of local authorities with the assistance of indigenous public organizations, development of new forms of management, creation of funds to support the indigenous small-numbered peoples, the use of natural resources of the area, fundrising. Attention is drawn to the greater social activity of indigenous peoples in crisis, their use of legal factors to defend collective interests, their cooperation with international organizations. It is noted that, despite the effectiveness of the measures taken to overcome the crisis, its negative consequences are felt to date. The article is based on the authors’ field materials, archival data, newspaper publications.
The economy of reindeer farms in the north-west of the Sakha Republic (Yakutia) in the XXI century: paternalism and independence
Authors: Kaduk Evgeny V.
Published: June 2019

Reindeer husbandry today occupies an important place in the policy of the Republic of Sakha (Yakutia) in relation to the regions of residence of the peoples of the North and also in the local municipal policy considered in the work of the Anabarsky district. The goals of the policy are to support and preserve the local culture and ensure the food security of the regions associated with reindeer herding. The reindeer breeders of Yuryung-Khaya today are building their economic strategies relying on the paternalistic policies pursued by the state, on the one hand, and actively using broader ties and entrepreneurial skills that were first demonstrated during the decline of the 1990s, on the other. In various contexts, ambivalence is manifested in the behavior of reindeer herders: alternating avoidance practices with the desire for greater autonomy and appeal to the authority of the state. Modern reindeer herders of Yuryung-Khaya to a greater or lesser extent use part of the available resources, not only to meet their primary needs, but also to improve their well-being and strengthen their household.
Aboriginal entrepreneurship in the Northern Ob region
Authors: Martynova Elena P.
Published: June 2019

he article deals with the history of the development of entrepreneurship in the Northern Ob region among the Nenets, Khanty and Mansi. The author calls it «aboriginal” meaning that it as an economic activity that makes profit from the works directly related to the traditional sectors of the economy of the indigenous North peoples or from sale of products of economy. The article is based on the author’s field materials obtained during many years of field research (2000, 2002, 2003, 2008, 2011, 2013, 2017 years) in different areas of Khanty–Mansi Autonomous Okrug and Yamalo-Nenets Autonomous Okrug.
It was found that two types of aboriginal entrepreneurship are developed in the Northern Ob region: institutional and informal. The first is represented by communities (either tribal or national) of indigenous people and farms. Their organization is socially oriented: communities are primarily a place of work for fishermen and reindeer herders. Community entrepreneurship is supported by the authorities of the district and the Okrug through a system of grants. The income of most community members is low, forcing them to seek additional income opportunities. The structure of communities of indigenous people is based on family ties.
Informal aboriginal entrepreneurship spontaneously emerged in the crisis of the 1990-s and still does not give up its position. It provides the main income to families of private reindeer herders and fishermen. As a result of this aboriginal business quite stable client networks are formed that contribute to the social integration of local communities. Such entrepreneurship brings higher incomes, compared with the legalized formal ones, despite the lack of support from the “top” of the authorities. This largely contributes to its stability in the harsh northern conditions, where the market is small. The risk of being deceived is not an obstacle to the development of such business.
The boundaries between institutional and informal economies in the North are penetrable and fluid. A private reindeer herder can be a member of the family community, and after delivering the minimum rate of products traditional industries can act as an independent businessman, selling products through his customers or visiting merchants. The same can be true for members of fishing communities. The interweaving of institutional and informal entrepreneurship forms a complex network of social and economic interaction in local communities.
Use of Reliability Block Diagram and Fault Tree Techniques in Reliability Analysis of Emergency Diesel Generators of Nuclear Power Plants
Authors: de Vasconcelos Vanderley , Soares Wellington Antonio , da Costa Antônio Carlos Lopes , Raso Amanda Laureano
Published: June 2019

Nuclear power plants (NPPs) are subjected to events such as equipment failures, human errors and common-cause failures, in an environment of complex maintenance, inspection and testing managements. These events will affect the reliability of safety-related systems, as well as the risk level of the plant. Reliability block diagram (RBD) is often used to analyze the effect of item failures on system availability, taking into account their physical arrangement in the system. Fault tree (FT) is a commonly used technique for analyzing risk and reliability in nuclear, aeronautical and chemical industries. It represents graphically the basic events that will cause an undesired top event. Loss of electrical power is one of the main events that influences safe operation of NPPs, as well as accident prevention and mitigation. In case of unavailability of offsite power, emergency diesel generators (EDGs) supply onsite electrical power. This paper carries out reliability analyses of EDGs of NPPs using both RBD and FT techniques. Each technique has its own advantages and disadvantages, allowing a variety of qualitative and quantitative analyses. Outcomes using these two techniques are compared for a typical NPP EDG system.

Authors: Gugulothu Srinu , Pasam Vamsi Krishna
Published: June 2019

In this study, an attempt is made to examine the machining response parameters in turning of AISI 1040 steel under different lubrication environment. Subsequently, design of experiment technique Response surface methodology (RSM) is used for analyzing machining performance by varying cutting conditions with the use of 2wt% of CNT/MoS2(1:2) HNCF. Regression models are developed for multiple machining responses. Optimization is performed for these models by using desirability function, which converts multi-objective into single objective. Then the optimal setting parameters for single objective is found. Significant reduction in main cutting force (Fz), cutting temperature (T), surface roughness(Ra) and tool flank wear (Vb) are found with the use of 2wt% of CNT/MoS2(1:2) HNCF compared to other lubrication environment. Significant factors that affect the main cutting force (Fz), the temperature in the cutting zone are cutting speed, feed rate and depth of cut. Parameter depth of cut has an insignificant effect on tool flank wear and surface roughness (Ra). The optimal cutting conditions for four multi-objective optimization of main cutting force (Fz), cutting temperature, surface roughness (Ra) and tool flank wear are found to be cutting speed 70.25 m/min, feed 0.13 mm/rev and doc 0.5mm at desirability value of 0.907.

Authors: Mondal Srijita , Ghosh Priyanka , Biswas Dibyendu , Roy Priti Kumar
Published: June 2019

Alcohol consumption is prevalent in HIV/AIDS infected patients. It possesses serious effects on protease inhibitors (PIs), which are used as an antiviral drug. While taking PIs, the secretion of Cytochrome P3A4 (CYP3A4) enzymes occurs from the liver and it metabolizes the drug to CYP3A4-PI complex. Alcohol consumption increases the rate of metabolism of PIs. In this research article, we have formulated a set of nonlinear differential equations based on the enzymatic activity of CYP3A4 for alcoholic HIV infected patients. Here, we have analytically compared the dynamics of PIs metabolism between alcoholic and non-alcoholic HIV infected patients and also investigated how the infection is being accelerated by enhancing viral load due to alcohol consumption. Finally, our analytical results are verified by numerical findings.
Design and Manufacture of Hob Mills for the Formation of Straight Slots Using the Principles of Screw Backing
Authors: Istotskiy V. , Protasev V.
Published: June 2019

The article shows the possibility of designing and manufacturing using multi-coordinate grinding and sharpening machines with CNC for workable worm mills for machining straight-slotted slots. Screw backing provides the necessary values of the rear side corners, and the ability of CNC machines to achieve the required accuracy and manufacturability of the tool. The lack of such tools consists in the increase of the diametrical sizes in comparison with the classically used ones. A positive effect when using the principles of screw backlash is the shaping of the cutting edges of the teeth in a checkerboard pattern, which significantly reduces the cutting forces. The use of techno-logical 3D models as a result of the design allows, at the design stage, to evaluate the arising design flaws and to make the necessary corrective actions into the initial data of the tool.

Authors: Mikheev V. , Grechnikova A. , Roslyakov A. , Agafonova D.
Published: June 2019

Three kinematic schemes are studied, which differ from one another in the route of technological operations. Each of these kinematic schemes has its own set of power stages of shaping and stages of free bending or bending of the ends of the sheet blank. In addition, the quantitative values of the angular parameters of a particular kinematic scheme are determined. Numerical experiments have been carried out, which give complete information about the distribution of the shell thickness as discrete values in one or another element. The result is statistical processing of this information, the scope of the predicted values and comparison with the tolerance on the thickness of the peel used in aviation enterprises.

Authors: Chaudhary Kamika , Gupta Neena
Published: June 2019

Web mining procedure helps the surfers to get the required information but finding the exact information is as good as finding a needle in a haystack. In this work, an intelligent prediction model using Tensor Flow environment for Graphics Processing Unit (GPU) devices has been designed to meet the challenges of speed and accuracy. The proposed approach is isolated into two stages: pre-processing and prediction. In the first phase, the procedure starts via looking through the URLs of various e-learning sites particular to computer science subjects. At that point, the content of looked through URLs are perused and after that from their keywords are produced identified with a particular subject in the wake of playing out the pre-processing of the content. Second phase is prediction that predicts query specific links of e-learning website. The proposed Intelligent E-learning through Web (IEW) has content mining, lexical analysis, classification and machine learning based prediction as its key features. Algorithms like SVM, Naïve Bayes, K-Nearest Neighbor, and Random Forest were tested and it was found that Random Forest gave an accuracy of 98.98%, SVM 42%, KNN 63% and Naïve Bayes 66%. Based on the results IEW uses Random forest for prediction.

Published: June 2019

Most of the engineering products are made with multiple components. The products with multiple subassemblies offer greater flexibility for parallel assembly operation and also disassembly operation during its end of life. Assembly cost and time can be minimized by reducing the number of assembly levels. In this paper, Elephant search algorithm is used to perform Optimal Assembly Sequence Planning (OASP) in order to minimize the number of assembly levels. Subassembly identification technique is used as an integral part of algorithm to identify the parallel assembly possibilities. The proposed method is implemented on industrial products and a detailed comparative assessment has been made with suitable product illustrations to corroborate the efficiency.
Effect of Cylinder Air Pressure and Hot Surface Temperature on Ignition Delay of Diesel Spray in a Constant Volume Combustion Chamber
Authors: Salman Mohammad , Kim Sung Chul
Published: July 2019

Present-day direct injection (DI) diesel engines with a high power density of displacement are not just promoting an expansion in the utilization of high-temperature resistant alloys in pistons yet, in addition, the expanded cylinder air pressures. When the temperature of the diesel engines piston exceeds a certain limit, it assumes a critical role at the start of sprays. The target of the present investigation was to look at the effects of cylinder air pressures (CAP) (10–25 bar) and high hot surface temperatures (HST) (350–450 °C). The ignition delay (ID) of pure diesel and that of diesel with Iftex clean system D (a cetane enhancer) are investigated experimentally. The experiments are performed by using a constant volume combustion chamber (CVCC) with a single hole pintle-type nozzle mounted on its head. A strong dependence of ID on the CAPs and HSTs was observed. A CAP of 25 bar is much inferior to the precombustion pressure of DI diesel engines; however, it is the case that combustion typical features are the same in spite of an inferior CAP, HST, and injection pressure. The ID tends to decrease to very small values with an increase in either of the two parameters. At a CAP of 25 bar, the measured ID of diesel with fuel additive is 45.8% lower than the pure diesel. Further, the ID of diesel with fuel additive at a 300 bar injection pressure and 25 bar CAP decreases at a rate of close to 0.2 ms/bar.
A short review of cable yarding applications in Australia
Authors: GHAFFARİYAN Mohammad Reza
Published: June 2019

The current
technology in Australia is mainly large swing tower yarder with grapple. These
yarders operate under whole tree or cut-to-length methods in steep terrains of
Victoria, Tasmania and South-East Queensland. Cable yarding is often applied in
clear fell operations in pine or Eucalypt stands in Australia. Felling
operations prior to yarding are carried out manually or using tracked
feller-bunchers. Typical terrains for applying cable yarding have slope larger
than 30°. There is currently a lack of small to medium size cable yarders that
can efficiently operates under different circumstances. Medium size capacity
yarders would be required to handle a wide range of situations under uphill and
downhill extractions while small capacity highly mobile yarders will be needed
for clean-up operations.
Developing an Inspection System between the Main Employer and the Sub-employers in terms of Occupational Health and Safety: A Case Study
Authors: KASAP Fahri , ACAR Hafiz Hulusi
Published: June 2019

A
healthier and safer working environment can be provided through a more
proactive approach with the different auditing systems. The relevant laws and
regulations must be developed and applied to employer and sub-employers within
the frame of an inspection system. The aim of the study is to examine the
primary employer and sub-employer relationship established under the roof of
large industrial enterprises in terms of occupational health and safety and to
create a healthy and safe working environment where legal requirements are
fulfilled. In situations where the primary employer and sub-employer
relationship is established within the work, the occupational health and safety
activities of the sub-employer need to be audited by the primary employer and
the matters to be audited have been determined. Four audits to be made by the principal
employer at least annually have revealed the situation in occupational health
and safety activities with numerical data. Within the scope of the study, the
audits conducted in 2017 on the primary employer and five affiliated
sub-employers, which were taken as models, have been explained. While the
primary employer and sub-employer relationship is continued by many authorities
as a matter of debate, this study sets forth a model about the creation of
legal responsibility and safe working environment. The audits must be made
sustainable.
