Scientific-and-Expert Community and Government: Specifics and Models of Interaction in the Siberian Federal District
Authors: Klimenkov Mihail
Published: October 2020

The present research featured the problems of interaction between scientific community and the local authorities in five regions of the Federal Siberian district: Kemerovo, Novosibirsk, and Tomsk regions, the Altai Territory, and the Republic of Tuva. The research objective was to identify and describe the dominant model of interaction between the scientific community and the authorities in Siberia. The study was based on the method of semi-structured expert interviews, which involved 34 scientists. The authors identified the level of subjectivity of regional scientific communities as groups of experts in the process of making political and state decisions. They also described the models and specifics in building interaction between scientists and the local authorities. The article introduces the main challenges to the process of building up an effective and collaborative relationship, namely the prevailing electoral-authoritarian regime and a weak expert function of the scientific community. The interaction was mostly represented by an informal (non-institutionalized) model with a poor involvement of expert community.

Authors: Kislyakov Mikhail , Vostrikov Konstantin
Published: October 2020

The research featured the Ethical Codes of state civil servants, which are to improve the efficiency of regional and federal management. The research objective was to analyze the content, problems, and prospects of Ethical Codes of civil servants as a factor in improving the efficiency of regional and federal management. The study was based on a comparative analysis and a sample method. The article considers the Ethical Codes introduced in several Siberian districts and their impact on the managerial and political practice. The Codes were an attempt of Siberian authorities to raise the prestige of public service in the local society with its complex economic and political processes. The authors conducted an expert survey, which suggests that the Ethical Codes adopted in the Siberian districts failed to improve the regional management. Therefore, the Federal Code of Ethics is necessary.
Modern Management Tools as a Basis for Increasing Efficiency of Cultural Institutions
Authors: Glushakova Olga
Published: October 2020

The present research featured official methods of efficiency assessment of cultural institutions. The existing system focuses on quantitative assessment and does not take into account the delayed social and economic effects associated with the quality of human capital. Therefore, the current system of indicators requires expansion. Cultural institutions acquire state or municipal support based on their compliance to efficiency criteria. The author analyzed the financial support provided for implementation of priority national projects. The amount of funds for the development of the cultural sphere appeared to be one of the smallest. The current global uncertainty and new challenges caused the budget funding focus to shift. Taking into consideration the growing variability of external environment, cultural institutions can become efficient only by using modern management tools. The author studied official approaches to assessing the efficiency of cultural institutions. The research objective was to justify the need to use modern management tools in order to increase the efficiency of cultural institutions. The study was based on the institutional approach, as well as the methods of analysis, synthesis, and comparison. The paper introduces some practical recommendations for the use of modern management tools and the application of national standards. The results can be of some interest to top management of cultural institutions. The author proposes systemic and process approaches for implementation of creative projects. She believes that PDCA methodology, benchmark and GAP analyses, and the method of key performance indicators will develop the dynamic capabilities of cultural institutions and increase their strategic flexibility in conditions of high external variability.

Authors: Kiryuhina Anzhelika
Published: October 2020

The state of employment on regional labor markets determines the economic development of the region. The present research owes its relevance to the problem of creating jobs on the Kuzbass labor market. The study involved data on vacancies offered in 24 local single-industry towns and posted on the website of the Department of Labor and Employment of the Kemerovo Region. The vacancies were grouped according to the register of spheres and types of professional activity. The professional qualification structure of the open vacancies was classified by the level and profile of education. A separate study was conducted for single-industry towns that possess the status of the territory of advanced social and economic development. The authors compared the open vacancies in these towns with the corresponding municipal development programs. The research objective was to identify areas of professional activity with the greatest shortage of personnel in Kuzbass single-industry towns. Enterprises in the region appeared understaffed with technical specialists with secondary vocational education. Most open vacancies were in the spheres of healthcare, transport, and industry. The study revealed a need to increase the prestige of qualified workers. The results can improve the efficiency of the employment service and educational institutions.

Authors: Sekletsova Ol'ga
Published: October 2020

Competitiveness ensures the effectiveness of the enterprise both in the long and short term of its activity within a particular market segment. This criterion reflects the enterprise's ability to meet the needs of customers and use available resources. It reflects the conformity of products to market requirements, as well as their qualitative and quantitative characteristics. Ice cream production sector will continue to grow in the medium term, and the industry's prospects will depend on the effective marketing policy. The present research assessed the competitiveness of Kemerovo Khladokombinat LLC (a refrigeration plant) on the local market of ice cream producers. It revealed the main directions for increasing the competitiveness of this enterprise. The assessment was based on the market position of the enterprise regarding the growth in demand for this product and the market share held by the enterprise. The analysis used a Boston Consulting Group (BCG) matrix. The analysis also involved the method of expert scoring and Michael Porter’s Five Forces model. A SWOT analysis helped to assess the market position of Kemerovo Khladokombinat LLC. The competitiveness of the company in question was assessed as high, compared to other enterprises engaged in the production and marketing of ice cream on the local market. The following recommendations can help the company to cement its place: Kemerovo Khladokombinat LLC should 1) strengthen its marketing component, 2) improve work with suppliers of raw materials in order to improve product quality and reduce production costs, 3) pay attention to its financial state.
Digital Regulation Model of the Dairy Industry in the Republic of Tuva
Authors: Chernyakova Irina
Published: October 2020

The research featured the development of effective digital technology for regulating the dairy industry. The study employed the innodiversification approach combined with simulation modeling. The empirical base was obtained from the databases of the national Union of milk producers. The authors proposed to apply the paradoxical theory of regulation. Its hypothesis is based on the fact that there is a relationship between the regulatory effect and the parameters of the dairy industry that do not have a functional relationship with it (the correlation coefficient approaching 0), through a multilevel chain of indirect relationships of parameters that are more connected with the regulator. The authors developed a mechanism that uses actual data from open sources and builds up digital models of the dairy industry of the Republic of Tuva. The article introduces a method of direct prediction of the parameters of the local dairy subcomplex. The method used not only an unregulated time factor but also the regulated factor of the state support funds. It calculated three different scenarios for the development of the dairy subcomplex: pessimistic, expected, and optimistic. In addition, the article offers a method of reverse prediction to calculate the necessary amount of state support that makes it possible to achieve the target parameters of the dairy subcomplex.
A one-dimensional semi-implicit finite volume modeling of non-inertia wave through rockfill dams
Authors: Sarkhosh Payam , Salama Amgad , Jin Yee-Chung
Published: October 2020

For hydraulic routing through coarse rockfill dams, there is still debate on whether the inertia terms might be neglected as a result of the drag force generated by the rock materials. In this study, a one-dimensional unsteady model for flow-through rockfill dams is built. For this purpose, inertia terms of Saint–Venant equations are disregarded. A semi-implicit scheme adopted for linearizing the nonlinear friction term within the time integration satisfies the Courant–Friedrich–Lewy stability criterion. The most challenging issue in the modeling of flows through rockfill dams is the appropriate definition of boundary conditions at the dam's exit zone. In addition to the analysis of different exit boundary conditions proposed in the literature, a Neumann-type boundary condition suitable for the non-inertia wave equation is also employed to estimate the exit boundary condition. This procedure is basically in appreciation of the nonlinear behavior of the water surface closer to the exit boundary. Due to the existence of the sloping edges in the trapezoidal-shaped dam, an effective length is considered for the solution domain. Finally, the model is compared with observed data and a dynamic wave model. A very good match is observed, which builds confidence in the presented modeling approach.
Comparison of parametric and non-parametric methods for trend identification in groundwater levels in Sirjan plain aquifer, Iran
Authors: Mirabbasi Rasoul , Ahmadi Farshad , Jhajharia Deepak
Published: October 2020

In the present study, five parametric and non-parametric methods: linear regression (LR), conventional Mann–Kendall (MK), modified Mann–Kendall (MMK), Spearman's Rho (SR) and Innovative Trend Method (ITM) were used to identify trends in the groundwater levels of 60 piezometers distributed uniformly across Sirjan plain, Iran, from 2005 to 2018. The LR method was found to be affected by the presence of outliers and autocorrelation. The conventional non-parametric tests (MK and SR) were not able to offset the effects of the autocorrelations between the groundwater level data. The ITM method was also found to be a not so comprehensive and precise statistical tool for trend analysis because it does not provide a quantitative index for identifying trend significance. Therefore, the MMK test was found to be the most appropriate trend analysis method among the five trend identification methods used in this study by eliminating the effect of all significant autocorrelation coefficients. The results of the MMK test showed that the groundwater levels in Sirjan plain had witnessed significant decreasing trends during the study period. In only 24 months (out of a total 10,080 studied months), no significant decreasing trends in groundwater levels were observed.

Published: October 2020

Drought indices that compute drought events by their statistical properties are essential stratagems for the estimation of the impact of drought events on a region. This research presents a quantitative investigation of drought events by analyzing drought characteristics, considering agro-meteorological aspects in the Heilongjiang Province of China during 1980 to 2015. To examine these aspects, the Standardized Soil Moisture Index (SSI), Standardized Precipitation Index (SPI), and Multivariate Standardized Drought Index (MSDI) were used to evaluate the drought characteristics. The results showed that almost half of the extreme and exceptional drought events occurred during 1990–92 and 2004–05. The spatiotemporal analysis of drought characteristics assisted in the estimation of the annual drought frequency (ADF, 1.20–2.70), long-term mean drought duration (MDD, 5–11 months), mean drought severity (MDS, −0.9 to −2.9), and mild conditions of mean drought intensity (MDI, −0.2 to −0.80) over the study area. The results obtained by MSDI reveal the drought onset and termination based on the combination of SPI and SSI, with onset being dominated by SPI and drought persistence being more similar to SSI behavior. The results of this study provide valuable information and can prove to be a reference framework to guide agricultural production in the region.

Authors: Faramarzmanesh Sasan , Mashal Mahmoud , Ebrahim Hashemi Garmdareh Seyyed
Published: October 2020

Excessive use of nitrate fertilizers in agriculture causes harm to humans and the environment. The most suitable nitrate removal process is heterotrophic biological denitrification. The purpose of the present study was to evaluate the performance of three shapes of denitrification bioreactors: triangular, rectangular and semicircular. The main element that was used to remove nitrate was beech woodchips. The concentration of inlet nitrate was 75 mg/l and the salinity of the solution was 1 ds/m and 5 ds/m, for a period of six months. The results showed that the efficiency of the triangular bioreactor with a salinity level of 1 ds/m was 90%, which is more efficient than the rectangular and semicircular bioreactors with performances of 55.8% and 53.8%, respectively. The results also indicated that at a salinity level of 5 ds/m, the semicircular bioreactor with a performance of 50.8% inlet nitrate removal was the best of the three shapes of bioreactors tested, the efficiencies of the triangular and rectangular bioreactors were 49.9% and 48.6% respectively. Also, it was observed that at the salinity level of 1 ds/m, a high hydraulic retention time had a high positive effect on denitrification, on the other hand at the salinity level of 5 ds/m, there was better performance of denitrification if the hydraulic retention time was lower.

Certain essential and conditionally essential natural elements (selenium, chromium, iodine, molybdenum, cobalt, vanadium, fluorine, lithium, silicon, boron, and bromine) are standardized in terms of their contents in drinking water as per sanitary-toxicological parameters of adverse health effects. Our research goal was to determine a contribution made by drinking water into supplying a human body with essential natural elements as well as to substantiate the necessity to update standards regarding these substances. We applied calculation models for dose equivalents of essential elements MPC (maximum permissible concentration), MPC calculations for these substances basing on a necessary 20 % contribution made by drinking water into reference doses, and calculation of non-carcinogenic health risks due to essential elements occurrence in specific drinking water sources with these elements being distributed into different groups as per similar effects produced on certain organs and systems in a body. We took existing drinking water sources containing 6 essential elements with similar effects as an example and applied a procedure for assessing non-carcinogenic health risks. Acting nickel and selenium MPC do not supply a body with an optimal daily intake whereas their determined MPC are not only harmless but also conform to the minimum necessary intake dose. At the same time neither acting lithium MPC nor its calculated one taking into account risk assessment based on internationally accepted reference doses doesn’t provide the minimum necessary daily intake into a human body. When boron and vanadium are contained in drinking water in a concentration close to their MPC, then their 20 % contribution into the reference dose is exceeded (71.4 % and 164.7 % accordingly). Introduction of these essential elements with food can become a factor that determines non-carcinogenic risk level.
Consumption of unregulated food items (false morels) and risk for neurodegenerative disease (amyotrophic lateral sclerosis)
Authors:   Oregon Health & Science University, Portland, Oregon, 97201, USA, Spencer P.S.
Published: October 2020

Unknown environmental factors are thought to contribute to the etiology of sporadic forms of amyotrophic lateral sclerosis (ALS). Strong evidence supporting this view is found in the post-World War decline and disappearance of highincidence ALS in three Western Pacific populations that formerly utilized neurotoxic cycad seed as a traditional source of food and/or medicine. The principal toxins in cycads (cycasin) and in False Morel mushrooms (gyromitrin) generate methyl free radicals that damage DNA and cause mutation and uncontrolled division of cycling cells and degeneration of late-/postmitotic neurons. Since False Morels are scavenged for food in Finland, Russia, Spain, and USA, research studies are underway in Western Europe and USA to determine if the practice is associated with sporadic ALS.

Hygienic assessment of combined effects produced by heterogeneous factors on comorbid diseases in the nervous system and digestive organs in children is vital for early detection and prevention of health disorders given existing risks and threats. Our research goal was to estimate probability of comorbid diseases in the nervous system and digestive organs in children attending primary schools under combined exposure to chemical factors and factors related to the educational process. Our research objects were factors related to the educational process that produced their effects on children aged 7–10 who attended primary schools with different educational programs; chemicals contents in ambient air and air inside classrooms as well as in children’s blood; biochemical parameters of negative effects; models showing cause-and-effect relations. Our research results allowed us to identify priority influencing factors and their share contributions into negative effects development in case there was comorbidity with nervous system diseases and digestive organs diseases; to give grounds for biological markers of negative effects applied for early diagnostics and development of activities aimed at preventing comorbid disorders for schoolchildren. Implementation of an algorithm for calculating and estimating probability of comorbid diseases in the nervous system and digestive organs under combined exposure to heterogeneous factors involves determining additional comorbidity cases among children who attend schools with more comprehensive educational programs in comparison with children attending ordinary schools. Timely and adequate correction of detected influencing factors and development of activities aimed at preventing comorbid health disorders will allow minimizing risks of comorbid diseases in the nervous system and digestive organs in school children under combined exposure to chemical factors existing in the environment and inside classroom and factors related to the educational process.

Public healthcare in Russia faces many challenges; meeting them requires non-standard and innovative approaches. The set tasks are being solved within the «Public healthcare development» State program. A sub-program within it is called «Development and implementation of innovative diagnostics, prevention, and treatment procedures as well as basics of personified medicine». This sub-program involves wide use of information and digital technologies. Personified medicine envisages developing such methods that would allow early detection of a probable disease even at a preliminary stage in examining a patient; this detection is to be based on a simple and relatively cheap diagnostic technology and to provide a medical center with reliable data on detected signs of a disease for a further diagnosis. Mass use of such technologies also requires truly reliable mathematic procedures and models for putting a preliminary diagnosis. At present cardiovascular diseases are still the leading cause of death all over the world; they develop due to variable factors including influence exerted by malignant neoplasms and also due to chemotherapy. The paper contains data collected by contemporary medical experts on case histories and complications of myeloproliferative diseases caused by vascular system pathology that holds the first rank place as per mortality worldwide. It was detected that both pathological cellular mass and medications applied to treat myeloproliferative neoplasms could produce adverse effects on vascular endothelium damage to which plays the leading role in cardiovascular continuum. To assess risks of myeloproliferative diseases complications, we examined patients using Laser Doppler Flowmetry (LDF). The results were processed with a logistic regression model. As per ROC-analysis results the obtained diagnostic criterion has sensitivity (1 – β) and specificity, (1 – α) that are equal to 0.87 and 0.96 accordingly, and it means diagnostics is high-quality. The procedure and the mode can be applied in digital medicine.

Peripheral and Central Glutamate Dyshomeostasis in Neurodegenerative Disorders
Authors: Onaolapo Adejoke Y. , Onaolapo Olakunle J.
Published: October 2020

Glutamate’s role as the major excitatory neurotransmitter of the mammalian central nervous
system requires that its brain concentrations be kept tightly-controlled. However, in hepatic
encephalopathy resulting from liver dysfunction; disruption of central neurotransmission and elevation
of brain glutamate levels have been observed. These had been associated with certain neurological
changes. While neurological changes resulting from hepatic encephalopathy are believed to be
transient, the discovery of alterations in liver enzymes in Alzheimer’s disease and the role of glutamate
and glutamate homeostasis in hepatic encephalopathy have piqued interests in the possible
role of glutamate, and glutamate homeostasis in neurodegenerative diseases. Here, we discuss the
evidence in support of the involvement of peripheral/central glutamate homeostasis in the development
of neurodegenerative disorders, as well as, the implications of such interactions in the development
of new therapies for neurodegenerative disorders.

Authors: Alblawi Adel , Keyani Saba , Nadeem S. , Issakhov Alibek , Alarifi Ibrahim M.
Published: October 2020

Objective:

In this paper, we consider a model that describes the ciliary beating in the form
of metachronal waves along with the effects of Magnetohydrodynamic fluid over a curved channel
with slip effects. This work aims at evaluating the effect of Magnetohydrodynamic (MHD) on the
steady two dimensional (2-D) mixed convection flow induced in carbon nanotubes. The work is done
for both the single wall nanotube and multiple wall nanotube. The right wall and the left wall possess
a metachronal wave that is travelling along the outer boundary of the channel.

Methods:

The wavelength is considered very large for cilia induced MHD flow. The governing linear
coupled equations are simplified by considering the approximations of long wavelength and small
Reynolds number. Exact solutions are obtained for temperature and velocity profiles. The analytical
expressions for the pressure gradient and wall shear stresses are obtained. The term for pressure rise
is obtained by applying Numerical integration method.

Results:

Numerical results of velocity profile are mentioned in a table form, for various values of
solid volume fraction, curvature, Hartmann number [M] and Casson fluid parameter [ζ]. The final
section of this paper is devoted to discussing the graphical results of temperature, pressure gradient,
pressure rise, shear stresses and stream functions.

Conclusion:

Velocity profile near the right wall of the channel decreases when we add nanoparticles
into our base fluid, whereas the opposite behaviour is depicted near the left wall due to ciliated tips,
whereas the temperature is an increasing function of B and γ and a decreasing function of Φ.

Intermedia and interlingual agenda setting: News coverage of the Ebola virus on Twitter (Preprint)
Authors: Al-Rawi Ahmed , Groshek Jacob
Published: October 2020

UNSTRUCTURED

The 2014 Ebola Virus Disease (EVD) outbreak captured substantial media attention around the world. This paper investigates the media coverage of Ebola in five pairs of English and Arabic international television media outlets (BBC, CNN, SkyNews, RT, and France24) by examining the headlines of 298,559 news stories that those respective organizations posted on their official Twitter accounts. Over the course of approximately one year’s worth of coverage on these networks, Ebola was mentioned in the headlines of 4,138 stories, which constitutes 1.38% of the total news coverage of all media outlets. Building on the theory of intermedia agenda setting that outlines the ways in which major news organization influence the agendas of other news outlets, the findings reported here indicate strong, time-ordered patterns where English language coverage consistently precedes and helps to significantly explain the distribution of Arabic media coverage. In addition to providing evidence of intermedia agenda setting from a comparative perspective in this context, this paper expands on this theory and suggests that it can be applied to multilingual outlets from the same news organizations.

Colonialidad del poder e historia global: cuestiones abiertas (Homenaje a Aníbal Quijano)
Authors: Benzi Daniele
Published: October 2020

En medio de nubarrones políticos y turbulencias económicas, en 2018 falleció una figura central del pensamiento crítico latinoamericano: Aníbal Quijano. En este artículo/homenaje se argumenta que sus escritos sobre la “colonialidad del poder” expresan al mismo tiempo la culminación y síntesis más original de las problemáticas debatidas en las ciencias sociales de la región en el siglo XX. Sin embargo, con el afán de contribuir a la discusión sobre un pensamiento crítico latinoamericano acorde con los desafíos del siglo XXI, también se plantea un conjunto de cuestiones que su legado intelectual deja abiertas. Ellas remiten, por un lado, a la profundidad y alcance de la “colonialidad del poder” a la luz de las interpretaciones de historia global y sociología macro-histórica sobre la expansión mundial europea. Por el otro, interrogan su vigencia a raíz del declive hegemónico estadounidense y de las dinámicas en curso en la economía política global del capitalismo.

Using life-cycle costing and the strategic profit model to enhance motor carrier capital equipment management
Authors: Hanna Joe B , Stapleton Andrew , Zoll Brian R
Published: October 2020

Participants in the increasingly competitive motor carrier industry are constantly trying to identify ways to enhance customer service levels and/or reduce costs. This research summarized case-based data from three large carriers to examine the use of life-cycle costing as a method to enhance motor carrier equipment management. The financial results of applying the technique are then examined by applying the Strategic Profit Model.
A comparison of implementation issues and strategies for radio frequency identification technologies between the U.S. military and private sector organizations
Authors: O'Brien Kristine M , Swartz Stephen M
Published: October 2020

The purpose of this research was to study the implementation of radio frequency identification (RFID) technologies used to track equipment and supplies. Current implementation issues and strategies for future use were collected from leading edge organizations from the military and private sector. A formal comparison found both similarities and differences between how industry and the Army are implementing and using RFID technologies in their supply chains and logistics networks. This article focuses on these similarities and differences, to include a gap between the Army and industry regarding RFID tag use and implementation, and a difference in the overall focus of how RFID tags are or plan to be used in both environments.
About item response theory models and how they work
Authors: Sedransk Nell
Published: October 2020

This article is about FMCSA data and its analysis. The article responds to the two-part question: How does an Item Response Theory (IRT) model work differently . . . or better than any other model? The response to the first part is a careful, completely non-technical exposition of the fundamentals for IRT models. It differentiates IRT models from other models by providing the rationale underlying IRT modeling and by using graphs to illustrate two key properties for data items. The response to the second part of the question about superiority of an IRT model is, “it depends.” For FMCSA data, serious challenges arise from complexity of the data and from heterogeneity of the carrier industry. Questions are posed that will need to be addressed to determine the success of the actual model developed and of the scoring system.
Rail - the left-out service alternative
Authors: Clowdis Charles W
Published: October 2020

The trucking industry faces a number of issues as it tries to meet growing demand for services. Trucking services are stifled by three factors: (1) strict enforcement of hours of service requirements which preclude carriers from meeting scheduled appointments; (2) over-the-road driver shortages; and (3) the absence of tort reform or federal preemption to trump nuclear judgments which reach upstream to shippers and brokers. However, rail may be an alternative for a growing number of commodities. This article examines the viability of rail services for the wine industry.

Published: October 2020

The fundamental properties of metal powders with small particles change, which opens up a wide range of applications of such materials. Currently, nanopowders are used in many industries to improve the quality of the resulting products. (Research purpose) The research purpose is in isolating a fine fraction of metal powders obtained by electroerosive dispersion for further experiments with this material, and also proving the possibility of obtaining such fractions by this method. (Materials and methods) A fine fraction of metal powders obtained by the method of electroerosive dispersion was isolated, which proved its effectiveness in obtaining conductive powder materials with the desired final physical and mechanical properties. This method results in a fairly large spread across fractions. Authors received material for research on experimental installations of the "Nano-Center" Center for Collective Use. The article presents the methods of experimental research of fractional composition on the example of metal powders of hard alloy grades T15K6 and VK8, copper powder M1, brass powder LTs38MTsS2 and bronze powder BrAZh9-12 obtained by electroerosive dispersion. (Results and discussion) The metal powder was divided into three fractions, depending on the particle size: more than 0.071 mm, from 0.02 to 0.071 mm and less than 0.02 mm. The presence of fine particles of less than 1.5 microns in the total mass of the studied powders was proved using a membrane method with a ceramic filter. Sedimentation showed specific sizes of minimal particles (from 86.4 to 116 nm). (Conclusions) Based on the results of experiments, it is possible to obtain metal powders of a fine fraction using the method of electroerosive dispersion.

Published: October 2020

Wear is most susceptible to parts of the cylinder-piston group and the gas distribution mechanism, in particular, camshafts, the main defect of which is the wear of the cams in height. It is important to identify the nature of wear and choose a rational method for restoring camshafts. (Research purpose) The research purpose is in increasing the reliability and durability of the restored camshafts by including an additional running-in operation with the introduction in the cam-pusher zone of a molybdenum disulfide modifier, which has antifriction, extreme-pressure and wear-resistant properties. (Materials and methods) Camshafts are made of low-carbon, medium-carbon steels and high-strength cast iron and are classified as parts of a complex configuration with high accuracy parameters; in their operation, the prevailing defect is the wear of the cams in height. For their recovery, a gas-thermal method of surfacing the cams was implemented with a GN-2 burner using self-fluxing Nickel-based alloys of the PG-CP2,3,4. (Results and discussion) The determining factors for the performance of restored gas-powder surfacing camshafts of diesel engines are not only physical characteristics (strength of adhesion of the coating to the base - adhesion, hardness, density), but also friction compatibility with the counterbody, workability and burr-proof. The article proposes to include in the technological process the operation of pre-run with the introduction of dry molybdenum disulfide (MoS2) into the run-in zone. (Conclusions) The use of dry friction with the help of molybdenum disulfide in the first stage of running-in prepares the friction surface for further engine running-in with the use of appropriate tribopreparations. Molybdenum disulfide in the friction surfaces accelerates the running-in of the surfaces, eliminates the possibility of scuffing, reduces the friction force and increases the service life of the repaired engine.
History of rye harvesting in the Soviet Union
Authors: Lyalyakin Valentin P.
Published: October 2020

Rye is one of the most important and valuable breads. It is very unpretentious to cultivation, it does not require fertile soils, it is cultivated even on acidic soils, it is frost-resistant, it can withstand drought. Harvesting rye before the introduction of combine harvesting was labor-intensive, requiring a large number of workers. (Research purpose) The research purpose is in presenting the existing technologies of rye harvesting in the pre-war and post-war years; to remember and pay a debt of gratitude to the many thousands of village workers who extracted valuable rye grain and provided bread to the country. (Materials and methods) The article reviews the existing technologies of rye harvesting at an early stage of the Soviet Union: manual harvesting with a sickle and horse harvesting with the use of reapers. (Results and discussion) The article shows the sequence of rye harvesting and describes techniques for working with a sickle; making sheaves, collecting them in fourths, transporting them to the thrashing floor; the technological process of threshing, gave a description of the power plant for driving the threshing drum. (Conclusions) The article presents technologies for harvesting rye in the pre-combine period, in which the author of the article participated. They are labor-intensive, but they arouse respect and sympathy for the workers of the village who harvested the valuable crop, rye.
