Представлены результаты исследований по изучению влияния нагрузки кустов побегами на плодоносность, урожайность растений, качество винограда и вина. Цель работы - установление закономерностей плодоношения, урожайности, качества винограда и вина сорта Первенец Магарача в зависимости от нормы нагрузки. Исследования проведены на корнесобственных виноградниках устойчивого к филлоксере сорта Первенец Магарача (морозостойкость от -22 до -25С), посаженных в 1986 г. по схеме 3 х 1,5 м, расположенных на территории опытного поля ВНИИВиВ им. Я.И. Потапенко (г. Новочеркасск, Ростовская обл.). Форма куста - двусторонний горизонтальный кордон с резервной основой в виде рукава и сучка восстановления. Агротехнические исследования проведены по общепринятым в виноградарстве методикам на промышленных виноградниках опытного поля ВНИИВиВ им. Я.И. Потапенко. Виноград перерабатывали по технологической схеме, принятой для приготовления сухих белых вин, химический анализ сусла и вина проводили в соответствии с методами, принятыми в энологической практике. Испытывали четыре нормы нагрузки побегами: 30, 35, 40 и 45 шт./ куст. По показателям плодоносности выделены варианты с нагрузкой 35 и 40 поб./куст (процент плодоносных побегов - 99 и 100; коэффициент плодоношения (К) - 1,97 и 1,95 соответственно); по количеству урожая выделен вариант с максимальной нагрузкой (45 поб./куст) - 23,1 т/га при самой низкой массовой концентрации сахаров в соке ягод (183 г/дм). Самые высокие значения этого показателя в варианте с самой низкой нагрузкой (30 поб./куст) - 196 г/дм. Показатели концентрации титруемых кислот в соке ягод по всем вариантам опыта были примерно равными. По качеству сусла выявлено снижение всех показателей с повышением нагрузки кустов урожаем. Лучшее вино было получено из винограда с нагрузкой 35 побегов на растение (8,6 балла). The article presents the results of studies on the effect of bush loading with shoots on their fruitfulness, yielding capacity, quality of grapes and wine. The purpose of work is to establish regularities of fruitfulness, yielding capacity, quality of grapes and wine of the variety ‘Pervenets Magaracha’, depending on the loading rate. The research was carried out on vineyards of the variety ‘Pervenets Magaracha’ resistant to phylloxera (frost resistance -22-25°С), planted in 1986 according to the scheme 3 x 1.5 m, located on the territory of experimental field of the Scientific Research Institute of Viticulture and Winemaking named after Ya.I. Potapenko (Novocherkassk, Rostov region). The bush shape was a two-sided horizontal cordon with a reserve base as a vine arm and a regeneration spur. Agrotechnical studies were carried out according to the generally accepted viticultural methods in the commercial vineyards of the experimental field of Scientific Research Institute of Viticulture and Winemaking named after Ya.I. Potapenko. Grapes were processed according to the technological scheme adopted for preparation of white dry wines. Chemical analysis of the must and wine was carried out in accordance with the methods adopted in oenological practice. We have tested four rates of loading with shoots: 30, 35, 40 and 45 pcs per bush. The variants of loading 35 and 40 shoots per bush stood out for the parameters of fruitfulness (the percentage of fruiting shoots was 99 and 100; the coefficient of fruiting (K1) - 1.97 and 1.95, respectively). According to the harvest amount- 23.1 t/ha, we selected the variant with the maximum load (45 shots per bush) with the lowest total sugars concentration in the juice of berries (183 g/dm). The highest value of this parameter in the variant with the lowest load (30 shots per bush) was 196 g/dm. Indicators of titratable acid concentration in berry juice for all variants of experiment were approximately the same. The quality of the must revealed a decrease in all parameters with an increase in the bush loading with the harvest. Better wine was obtained from the grape variant with a load of 35 shoots per plant (8.6 points).

The examination of deburring and surface finishing (DSF) quality was held at the enterprises of Russia. Here are the results of the examination. It was held on the base of general conclusion from the Scientific Research Institute “V and T” investigation results. The practical use of DSF at the engineering plants was also taken into account.

The article presents an analytical report about the activity of Scientific-research Institute of Traumatology and Orthopedics clinic for the period of 2015-2019 years. For the analysis of the in-patient clinic statistics annual report on the work of the hospital were used (Form 30), section 3 «Bedspace and its use» and the form 14 “Report on the activities of the in-patient clinic for the period of a year”, form 17 "Report on medical and pharmaceutical shots". On top of that, there were made the analysis of conjunctural reports of heads of functional departments of clinic. Except it, the analysis of quality of providing of medicare is conducted

The purpose of the work was to study the nosological structure of rheumatologic patients hospitalized  in emergency hospitals. The analysis of the obtained distribution and its comparison with the structure  of patients at the Scientific Research Institute of emergency care named after I. I. Djanelidze and the City  Rheumatology Center were done. Determination of the current structure of hospitalization of rheumatologic  patients can serve as a basis of its forecasting for the subsequent periods.

The article has been prepared on the basis of many years of research at the Central Scientific Research Institute of Urban Development in the 1970s and 1990s and later works, including those carried out at the Central Scientific Research Institute of Construction of the Ministry of Construction of Russia. The ecological prerequisites of urban planning and the principle of the formation of the natural-ecological frame of the territories of cities as a planning basis for their improvement and landscaping are considered. Taken into account studies of 2019-2020. Since the beginning of the new century, the professional environment has been discussing the negative trends of modern urban planning and urban improvement, accompanied by the loss of their individual appearance. This takes place in the conditions of a market economy and world processes of globalization, which in our subject area are usually called "urbanism". This situation is typical for most cities, and not only for megalopolises, but also for small historical cities. It is shown that excessive unification and depersonalization of the urban environment can be overcome by relying on the fundamental achievements of domestic science and practice. It is also necessary to use systemic, socially oriented and environmentally oriented approaches to the planning and improvement of cities with the formation of interconnected systems of natural and green areas. They should include historical buildings, architectural ensembles and architectural monuments, valuable natural landscapes, historical gardens and parks.
