The article discusses the method of strengthening the subgrade and non-rigid road pavements, in areas with weak soils. The use of geosynthetic materials has a positive effect on the condition of the roadbed and pavement, especially in the conditions of the increased traffic load in recent years. The work performed allows us to reduce the cost of operating highways since the construction of the pavement will last longer when used in the difficult natural and climatic conditions of our country.

The correct operation of the continuous welded track requires diagnosing its condition and preparation of track metrics requiring measurements of displacements of rail under operation. This is required as there are additional thermal stresses in the rails with values depending on the temperature changes of the rails. Therefore, the climatic conditions are important. This paper presents the original effective analytical method for diagnosing the condition of continuous welded track based on experimental research. The method allows for an appropriate repair or maintenance recommendation. In the experimental research, the authors considered track diagnostic conditions for two conditions: track under load and track without load. This paper presents empirical formulas for calculating rail temperature and longitudinal force based on ambient temperature, developed from long-term measurements. The formulas were developed for a track located on a straight section—both for a rail loaded and unloaded with a passing train under the following conditions: 60E1 rail, not on an engineering structure, conventional surface, wooden sleepers and very high train traffic load. The obtained results in the value of the correlation coefficient R2 ≥ 0.995 attest to very high accuracy of the calculations performed with the method proposed by the authors.

Большое значение в увеличении продуктивности картофеля имеет внедрение в производство перспективных высокоурожайных сортов и гибридов, приспособленных к местным природно-климатическим условиям возделывания, от чего зависят эффективность отрасли и себестоимость продукции. Цель работы – изучить влияние климатических условий на продуктивность и качественные показатели сортов и гибридов картофеля, а также использование ими благоприятных почвенно-климатических условий высокогорья Республики Дагестан, для размножения и внедрения в производство новых перспективных, высокоурожайных, приспособленных к условиям среды выращивания сортов картофеля с комплексом хозяйственно-ценных признаков. Объектом изучения послужили сорта картофеля раннего, среднераннего и среднего сроков созревания российской, белорусской и иностранной селекции. Полевые опыты закладывали в 2014–2017 годах на высоте 2000–2200 м, на землях горного опорного пункта «Курахский» Курахского района и на равнинной провинции (Прикаспийской низменности) на территории дачного массива «Наука» Махачкалинского района Республики Дагестан. Схема посадки – 70×30 см, повторность – четырехкратная. Технология выращивания картофеля – гребневая. При проведении полевых опытов использовали общепринятые методики. Практически все сорта картофеля, выращенные на равнинной провинции, сформировали высокий урожай в первый год и при дальнейшем размножении в результате развития вирусных болезней резко снизили свои продуктивные качества. Наиболее высокая урожайность в среднем за три года отмечена у сортов Жуковский ранний (20,8 т/га), Импала (20,5 т/га), Невский (17,8 т/га), Предгорный (16,9 т/га) и Удача (16,3 т/га). В свою очередь, горная провинция Дагестана характеризовалась благоприятными почвенно-климатическими условиями для возделывания как продовольственного картофеля, так и для организации первичного семеноводства на безвирусной основе и размножения перспективных сортов этой культуры. В среднем за годы исследований в горной провинции по урожайности выделились сорта Сильвана (37,4 т/га), Удача (37,6 т/га), Рокко (33,3 т/га), Импала (31,7 т/га), Жуковский ранний (29,0 т/га), Предгорный (27,7 т/га) и Примобелла (27,7 т/га), а также гибриды № 12.40/17 (43,1 т/га) и № 13.61/61 (38,8 т/га). The introduction of promising high-yielding varieties and hybrids adapted to the local natural and climatic conditions of cultivation is of great importance in increasing the productivity of potatoes, which determines the efficiency of the industry and the cost of production. The aim of the work is to study the influence of climatic conditions on the productivity and quality indicators of potato varieties and hybrids, as well as their use of favorable soil and climatic conditions in the highlands of the Republic of Dagestan, for breeding and introducing into production new promising, high-yielding, adapted to the growing environment of potato varieties with a complex of economically valuable characteristics. The object of the study was potato varieties of early, mid-early and medium maturation periods of Russian, Belarusian and foreign selection. Field experiments were conducted in 2014–2017 at an altitude of 2000–2200 m, on the lands of the mountain stronghold Kurakhsky of the Kukhar district and on the plain province (the Caspian lowland) on the territory of the suburban area Nauka of the Makhachkala district of the Republic of Dagestan. The landing scheme is 70×30 cm, the repeatability is four times. The technology of growing potatoes is combed. When conducting field experiments, generally accepted methods were used. Almost all potato varieties grown in the lowland province formed a high yield in the first year and, with further propagation, as a result of the development of viral diseases, sharply reduced their productive qualities. The highest yield on average for three years was observed in the varieties Zhukovskiy ranniy (20.8 t/ha), Impala (20.5 t/ha), Nevsky (17.8 t/ha), Predgornyy (16.9 t/ha) and Udacha (16.3 t/ha). In turn, the mountain province of Dagestan was characterized by favorable soil and climatic conditions for the cultivation of both food potatoes, and for the organization of primary seed production on a virus-free basis and the reproduction of promising varieties of this crop. On average, over the years of research in the mountain province, the varieties Silvana (37.4 t/ha), Udacha (37.6 t/ha), Rocco (33.3 t/ha), Impala (31.7 t/ha), Zhukovskiy ranniy (29.0 t/ha), Predgornyy (27.7 t/ha) and Primobella (27.7 t/ha), as well as hybrids No.12.40/17 (43.1 t/ha) and No.13.61/61 (38.8 t/ha) were distinguished by yield.

Solar energy is widely used in solar systems, where economy and ecology are combined. Namely, this represents an important moment in the era of depletion of energy resources. The use of solar energy is a promising economical item for all countries of the world, meeting their interests also in terms of energy independence, thanks to which it is confidently gaining a stable position in the global energy sector. The cost of heat obtained through the use of solar installations largely depends on the radiation and climatic conditions of the area where the solar installation is used. The climatic conditions of our country, especially the south, make it possible to use the energy of the Sun to cover a significant part of the need for heat. A decrease in the reserves of fossil fuel and its rise in price have led to the development of optimal technical solutions, efficiency and economic feasibility of using solar installations. And today this is no longer an idle curiosity, but a conscious desire of homeowners to save not only their financial budget, but also health, which is possible only with the use of alternative energy sources, such as: double-circuit solar installations, geothermal heat pumps (HP), wind power generators. The problem is especially acute in the heat supply of housing and communal services (HCS), where the cost of fuel for heat production is several times higher than the cost of electricity. The main disadvantages of centralized heat supply sources are low energy, economic and environmental efficiency. And high transport tariffs for the delivery of energy carriers and frequent accidents on heating mains exacerbate the negative factors inherent in traditional district heating. One of the most effective energy-saving methods that make it possible to save fossil fuel, reduce environmental pollution, and meet the needs of consumers in process heat is the use of heat pump technologies for heat production.

Currently, to increase the efficiency of industrial production, high-performance and expensive technological equipment is increasingly used, in which the weakest link, from the point of view of efficiency and reliability, is the components and parts of heavily loaded tribo – couplings operating both at significantly different temperatures (conditionally under lighter conditions, the temperature difference can be 100-120 degrees) and climatic conditions (high humidity, the presence of abrasives and other chemical elements in the atmosphere). As the results of the analysis of the frequency of failures of friction units and, accordingly, the cost of their restoration reach 9-20 percent of the cost of all equipment, without taking into account significant losses of income (profit) of the enterprise from downtime. The solution of this problem is based on the study of the wear rate of friction units by the wear products accumulated in working oils, cooling lubricants, and greases. A digital equipment monitoring system (DSMT) has been developed and implemented, which includes dynamic recording of the number of wear products and oil temperature by original modern recording devices, followed by the technology of their processing and use. The system also includes methods for finding the necessary information in large data sets useful and necessary in theoretical and practical terms with a similar technique controlled by a digital monitoring system. The advantages of SMT are the ability to predict the reliability of the equipment; reduce production risks and significantly reduce inefficient costs.

Abstract Background Future physicians may not be prepared for the challenges of caring for the growing population of poor patients in this country. Given the potential for a socioeconomic “gulf” between physicians and patients and the lack of curricula that address the specific needs of poor patients, resident knowledge about caring for this underserved population is low. Intervention We created a 2-day Resident Academy orientation, before the start of residency training, to improve community knowledge and address resident attitudes toward poor patients through team-based experiential activities. We collected demographic and satisfaction data through anonymous presurvey and postsurvey t tests, and descriptive analysis of the quantitative data were conducted. Qualitative comments from open-ended questions were reviewed, coded, and divided into themes. We also offer information on the cost and replicability of the Academy. Results Residents rated most components of the Academy as “very good” or “excellent.” Satisfaction scores were higher among residents in primary care training programs than among residents in nonprimary care programs for most Academy elements. Qualitative data demonstrated an overall positive effect on resident knowledge and attitudes about community resource availability for underserved patients, and the challenges of poor patients to access high-quality health care. Conclusions The Resident Academy orientation improved knowledge and attitudes of new residents before the start of residency, and residents were satisfied with the experience. The commitment of institutional leaders is essential for success.

The economic efficiency of the cultivation of grapes as a branch of agriculture depends on the adaptation of grape varieties to the soil and climatic conditions of the place of growth. When developing new agricultural practices and technological solutions for the cultivation of grapes, it is necessary to assess the econom-ic efficiency of the proposed innovative ap-proaches. The cultivation of such grape varie-ties is becoming important and relevant, which, with high productivity and the use of differen-tiated care technology, require minimal costs when servicing the bushes and harvesting. In-creasing labor productivity in the viticulture industry is the most important condition for the intensive development of production. One of these conditions today is the formation of a bush according to the technology element, the shape of a bush AZOS-1, which allows to re-duce the cost of care and harvesting of grapes. The conducted research on the technology of cultivation of table grape varieties in connec-tion with the use of a new form of bush made it possible to economically substantiate the economic efficiency of growing grapes.

The purpose of the article is to assess the pace of capital contribution and investment in solar energy in order to increase the energy security of national economies. The study analyzes the development of the global solar industry for years 2009-2019 in the context of investment support. The main stages of development of world solar energy are marked and the priority of countries and regions is determined. Factors of attractiveness of solar energy for private investment are noted, namely the investment climate is formed at the expense of legislative maintenance of this sphere, and in the economic plan at the expense of introduction of the «green» tariff. Two main investment processes in the development of solar energy are noted. First, these are large private companies that implement large-scale projects from solar stations. Secondly, this small private investment to provide electric for households that identified a small city urbanization and climatic conditions. It was found that the solar energy market depends more on capital intensity than on resource intensity. The result of economic calculation is indicated, which allowed to determine the term of reduction of the cost price of 1 kW of photovoltaic power station electricity to the level of NPP production cost for ten years.

Currently, the modern poultry farms are located in regions with different climatic conditions. Thus, the component of the electric power being the base for combined heating and ventilating systems, lighting, and local heating of poultry farms, is great in power engineering on the territory of the Russian Federation. The analysis of energy costs of poultry farms showed that of the estimated options for reducing the cost of electricity for poultry farms, one of the most effective can be an alternative source such as the generation of own electricity. Naturally, for biological production with a continuous technological cycle (poultry farming, for example), seems to be replace about 45-55 % of the needs of the factory and serve as a reserve for the rest, but not cover all 100 % of needs.

The results of the study of the classification of occupational safety costs, in particular the classification of costs for medical examinations, according to the current requirements of the regulatory legal acts and documents of the Republic of Kazakhstan are presented. The Labor Code of the Republic of Kazakhstan does not regulate the cost of financing occupational safety costs in the organizations. In addition, there are no state-approved methodology for planning and occupational safety budgeting costs. International research in the field of occupational safety confirms the positive effect of the investments in occupational safety on the competitiveness, productivity, and sustainability of the enterprise at the market. At the same time, the methodologically sound organization of planning and financing of occupational safety costs depends on their correct classification, which further contributes to the construction of a rational budgetary system of the enterprise in the field of occupational safety. The need for cost classification is due to the fact, that the existing occupational safety activities have different signs and types of costs. In the process of the study the empirical data is used, for example, codes, laws, and other regulatory legal acts of the Republic of Kazakhstan, as well as the scientific research from near and far abroad. The paper offers three signs of the classification of occupational safety costs. In accordance with the proposed signs of cost classification, the types of medical examinations that employers are legally required to conduct for their employees are distributed. Thus, the classification of occupational safety costs, which is aimed at the cost management, should consider all the main options for solving managerial tasks of the enterprise in the field of occupational safety, and should be applicable in practice. At the same time, the classification of costs with varying degrees of detail contributes to the sound planning and financing of the costs for employee occupational safety, which will lead to a positive result from the investment.
