Measures to support Russian tourism in the conditions of the Covid-19 coronavirus pandemic

The tourism industry, including the hospitality industry, which were the first to suffer from the new coronavirus pandemic, found themselves in an unprecedented situation: complete cessation of some businesses due to border closures and self-isolation. For some countries tourism makes up one of the largest shares of GDP and is a key industry, for others, tourism and activities associated with international travel significantly accelerate the pace of economic development. Industry actors need to understand what incentive tools are available now and in the aftermath of the pandemic in order to develop a systematic approach to managing the effects of the pandemic. The purpose of the article is to study and structure incentive measures for the tourism industry in the context of the COVID-19 pandemic. The following methods of scientific knowledge has been used: abstraction, analysis, induction, synthesis. The article substantiates the relevance of the study. Some indicators of the functioning of domestic tourism during a pandemic are considered in comparison with previous periods, in particular, price indices for various types of paid services to the population, the development of collective accommodation facilities in Russia. At the same time, there is a decline in all indicators during the pandemic, which is due to forced quarantine restrictions and the closure of borders in most countries of the world. The most popular measures of state support proposed by the government for the tourism sector are the following: support in obtaining financing, tax incentives, subsidizing operating expenses, subsidies for SMEs (minimum wages), deferral of non-tax payments, consulting and educational support, deferrals and incentives for rent payments, provision of grants and subsidies on a competition, etc. The proposed measures to support tourism in the current environment are new personnel training, assistance in developing a strategy, business development, attracting tourists, assistance in the transition to online, facilitation of activities (tax, financial, regulatory exemptions).

Dispersion of watermelon rinds as secondary raw materials in technologies of pectin-containing extracts and film structures

The development of protective coatings based on pectin substances that serve as natural structure-forming agents developed from a secondary resource base is focused on removing a complex problem in the production of finished products by deep processing of basic raw materials and developing an original film material. At the same time, the technical result of obtaining pectin-containing film structures is their ability to protect food products from microbiological spoilage, natural losses during storage and the preservation of quality and safety indicators. An important preparatory procedure that determines the efficiency and intensity of extraction processes can be attributed to the operation of dispersing the feedstock, since it directly affects the size of the contact surface area of the phases involved in mass transfer. However, it is clear that the greater the degree of grinding, the higher the efficiency of the process, but an excessive increase can lead to additional unjustified energy costs and, as a result, to an increase in the cost of the finished products sold. In this regard, the purpose of the research is to analyze existing technologies for producing pectin-containing extracts, in which watermelon rinds can be used as secondary resources and to intensify the extraction process by conducting a rational preparatory procedure for grinding the raw materials. The object of the research are watermelon rinds as non-recyclable waste from processing watermelon raw materials. According to the obtained graphs, and taking into account the high rates of gelatinization of the obtained pectin extracts, it is possible to recommend a complex treatment of watermelon rinds, including, in addition to the operations of preliminary preparation of raw materials, ultrasonic exposure and acid hydrolysis, and it is desirable to use food acids, for example, acetic or citric, instead of aggressive sulfuric and hydrochloric acids. As a result of the study of the dispersed composition, it has been concluded that the average equivalent particle size of the dispersed raw materials does not exceed the recommended limits, that is, the result obtained can be considered acceptable.

Investigation of regularities of occurrence of external effects of education and their significance for the economic development

The aim of the research is to assess the quantitative impact of education on the emergence of externalities and economic development. It has been shown that the increase in the education of specialists in interaction with innovative activity contributes to the emergence of external effects, which have a high level of significance for economic dynamics. As a result, the total contribution to GDP, as a result of an additional year of study for a specialist with a higher education, increases by about 50%. Realizing this effect, the largest economies of the world (the USA, the European Union, China and Japan) have been increasing the share of specialists with tertiary (vocational) education approximately linearly at a rate of 0,8 ±0,2% per year over the past 25 years. For Russia, the positive effect of a high level of tertiary education is significantly reduced due to the problems of interaction with the economic environment. The income that innovators themselves receive is, in a significant proportion of cases, relatively small. In particular, for the «Open Distance Education» innovation, the innovator's income was about 0,3% of the income of other recipients of benefits from the innovation. A significantly large share of the income from innovation is realized as an external effect of other users of the innovation, especially the consumers of the manufactured products and followers. Quantitative estimates of the external contribution to GDP of the innovation «Open Distance Education» show that they amount to about 14 thousand dollars per graduate, and only 340 million dollars a year. The findings can be used to assess the impact of education and develop strategies for staff training and innovation development.

Development of the technology of «Mozzarella» goat cheese with specified functional properties

The article shows the prospects for the production of Mozzarella cheese of goat milk and dry sourdough. Cheese contains vital nutritional components, they are biologically complete and play an important role in the diet. Searching for new resources is an urgent problem. The solution may be to expand the range of cheeses not only of cow milk, but also of other farm animals, for example, goats. Their milk is absorbed faster and is used in medical and preventive nutrition. On the consumer market goat milk products are mainly represented by farms, and their range is small. The authors carried out the research on the selection of starter cultures containing probiotic cultures from bifidobacteria, acidophilus bacillus and thermophilic streptococcus, to optimize the technological process for the production of Mozzarella cheese based on goat milk. These cultures represent a beneficial microflora that inhabits the human body, helping to absorb nutrients and digest food. An important quality of probiotics that ensures their physiological effect is their high growth rate and compatibility with other microorganisms present in the gastrointestinal tract. It has been found that all the studied samples of goat milk in terms of composition have indicators that meet the requirements of GOST for goat milk. Comparative analysis of cow and goat milk has shown predominant indicators of the quality of goat milk in comparison with cow milk. The processes of coagulation and fermentation of goat milk under the influence of various starter cultures have been studied. The use of ABT-5-Probio-TecTM probiotic starter culture, which accelerates the technological process and imparts functional properties to the product, has been substantiated. The possibility of using goat milk in the production of cheeses with cheddaring and thermomechanical processing has been proven. Microscopic examination of a sample of Mozzarella cheese on ABT-5 sourdough has shown that bifidobacteria survive after heat treatment at high temperatures.

Refinement of the methodology for assessing the resistance of hazel (hazelnuts) to stress factors

The aim of the research is to clarify the methodology for assessing the resistance of hazel (hazelnuts) to stress factors on the basis of uniform approaches adopted in walnut farming. The assessment of resistance to biotic and abiotic factors has been carried out according to the methods recommended for the walnut, and the state of the vegetative and generative organs of hazel (hazelnuts) has been correlated with the program requirements. The result has been the development of 7 point assessment scales and the numerical values of the degree of damage correlated with them. Score 0 corresponds to the absence of lesions, 1 – lesions up to 5%, 2 – lesions up to 6–10%, 3 – lesions up to 11–25%, 4 – lesions up to 26–50%, 5 – lesions up to 51–75%, 6 – lesions more than 75% or death of the whole plant (depending on the studied indicator). The assessment scale for the winter hardiness of vegetative organs takes into account the degree of damage to the apical buds, annual shoots, branches of two years and older, the stem and the whole plant. Damage to male inflorescences is determined by the length of their dead part, to the female flowers – by the number of damaged ones, expressed as a percentage. The degree of drought resistance is revealed on the basis of studying the state of the entire plant, the percentage of damaged and fallen leaves. The influence of drought on the loss of food part is established by the degree of shrinkage of the kernel. Susceptibility to diseases and pests is estimated in percentage points separately for leaves by area, shoots in length, nuts by the ratio of damaged and undamaged ones. We have distinguished 6 groups of resistance, depending on the degree of vulnerability of varieties and forms of hazel (hazelnuts). It has been proposed to draw conclusions on the basis of at least three years of observations, and the final conclusion should be focused on specific breeding goals.

Estimation of the efficiency of the «soy – winter wheat» crop rotation link and its influence on soil properties

Crop rotation is a systematic solution to one of the main tasks of agricultural production: rational land management, taking into account their possible effective fertility, biological potential of cultivated plants and available external and internal resources (heat, climate, fertilizers, agricultural machinery and agrochemicals) in order to maintain the most economically efficient management, which is possible with consistently high yields, with consistent reproduction of soil fertility and protection of the external environment. And as a consequence, crop rotation in this case acts as the basis of modern zonal adaptive landscape farming systems. It defines most other systems: soil cultivation and protection from erosion processes, fertilization and plant protection systems, seed production and variety change, irrigation and drainage of lands, technical systems, labor organization, etc. crop rotation «soybean-winter wheat» on merged leached chernozems and its effect on soil properties in the southern foothill zone of the Western Ciscaucasia. As a result of the study, a comprehensive assessment of the productivity of the «soybean-winter wheat» link in the crop rotation has been carried out and its positive effect on agrophysical and agrochemical properties of merged chernozems determined. It has been established that in order to obtain high-quality soybean seeds of the Mentor variety with the corresponding qualities of «the winter wheat» predecessor in the foothill zone of Adygea, it is necessary to use early sevarian conditions at a seeding rate of 0,6 million pieces/ha and a row spacing of 15 and 30 cm. To acieve a high level of production profitability, winter wheat of the Alekseich variety should be placed according to the «soybeans» predecessor against the background of surface tillage (10–12 cm). At the same time, it is proposed to apply mineral fertilizers at a rate of 200 kg/ha in the form of sulfoammophos N20P20S8, with obligatory double spring feeding of 150 kg/ha with ammonium nitrate N51+N51.

Changes in the physiological state of peach plants influenced by drought

The article presents experimental data on physiological and biochemical studies of stone fruit culture on the example of Persica vulgaris (Mill.) In the humid subtropics of Russia. The research has been carried out since 2011 in the Laboratory of plant physiology and biochemistry of the Subtropical Scientific Center of the Russian Academy of Sciences on peach varieties of different ripening periods grown in the humid subtropics of Russia. To identify any physiological changes in the body of peach plants during drought, especially in summer, comprehensive diagnostic studies of the water regime (leaf turgidity, determination of the thickness of the leaf blade, water deficiency) and pigment composition are carried out, characterizing the functional state of peach plants. Under unfavorable conditions, promising varieties have a higher ratio of chlorophylls to carotenoids, which confirms their more developed adaptive potential. Studies of this nature have been carried out in order to identify and select resistant peach plants among the studied varieties, which would correspond to the humid region of the Black Sea coast of the Krasnodar Territory. In the subtropical zone of our region, the issue of drought resistance has always been acute, since the impact of negative environmental factors (cool spring, accompanied by drizzling rains and a long summer shortage of air and soil moisture) on peach plants lead to a decrease in productivity and a deterioration in the quality of fruits, which makes their unsuitable and non-transportable. It has been found that among the tested plants, peach varieties Maycrest, Fayet, Larisa have been distinguished by high physiological indicators, such as: low water deficiency – 12,20–14,65%, leaf turgidity ­– 0,18 mm, saturation of leaf tissues within 70,12–79,21%, the content of carotenoids is 0,5–0,7 units, which is a confirming sign of their high resistance to the negative effects of weather conditions in the south of Russia.

Features of the formation of winter wheat yield depending on the methods of basic tillage and the level of fertilization in the conditions of the southern foothill zone of the North-West Caucasus

The research was out on low-humus heavy-duty heavy-clay merged leached chernozems in 2017–2020 in the Republic of Adygea, in the soybeans – winter wheat link of crop rotation. We studied the effect of soil cultivation techniques of varying intensity and fertilization level on the productivity of winter wheat and the agrophysical properties of the soil in its crops. The studies were carried out according to the method of the field experiment by B.A. Dospekhov. It was found that moldboard plowing was a more effective method for cultivating winter wheat, which provided additional formation of +1,18 t/ha (25,7%) of grain in comparison with double disking; sowing of winter wheat provided the maximum yield on the variants with the application of doses of Fon mineral fertilizers (N24 P104 + N5 P20) + N30 + N30, which contributed to the receipt of an additional +0,9 t/ha (18.8%) of grain. The effectiveness of the use of fertilizers for all varieties and doses of fertilizers according to the variants of the experiment was noted. Close correlations between productivity and a set of characteristics: the mass of grain from one spike; the number of grains in an ear; weight of 1000 grains; the total number of plants and productive stems were revealed. The positive effect of plowing on the structural and aggregate composition of the soil was noted. The average indices of the volumetric mass of the cultivated layer by both methods of cultivation did not exceed the optimal values of soil density for the cultivation of winter wheat (1,24–1,27 g/cm3). Productive moisture reserves were assessed as good and satisfactory. It was found that from 51,0 to 88,0% of the yield variability depended on the influence and mutual influence of the most significant elements of the yield structure (R2 is the coefficient of determination 0,88; 0,77; 0,51).

Evaluation of the debt policy of the southern macroregion subjects in modern conditions

The relevance of the topic is due to the fact that debt crises have an extremely negative impact on the national economy, which implies the need for constant attention on the part of the government to issues of public debt management in order to timely, identify possible violations of debt stability. The subject of the research is the debt sustainability of the constituent entities of the South of Russia as the ability of the constituent entities of the federation to timely and fully service the public debt without significant adjustments to the balance of income and expenses. The aim of the research is to assess the debt sustainability of the constituent entities of the South of Russia and develop measures aimed at increasing it in order to prevent the emergence of an imbalance in regional finances and reduce the likelihood of debt crises. An increase in government borrowing rises budget spending on public debt servicing and can provoke an imbalance in the financial system. Diversification of the debt portfolio helps to ensure its balance. The structure of the debt portfolios of the constituent entities of the Federation may include budget loans, government guarantees, government securities, loans from credit institutions and other instruments. The article notes that the debt sustainability of the constituent entities of the Russian Federation directly depends on the decisions made at the federal level and the amount of government spending directed to specific regions. Therefore, it is necessary to maintain such a level of debt sustainability, which will prevent the emergence of an imbalance in regional finances and reduce the likelihood of debt crises. This presupposes the application of uniform recommendations for assessing debt sustainability in all constituent entities of the Russian Federation. The analysis of the volume and structure of the state debt of the constituent entities of the South of Russia, carried out in the article, made it possible to conclude that the debt policy of the macroregion is fragmented: the structure of debt portfolios is heterogeneous; a change in the level of debt burden can be associated with both an increase in tax and non-tax revenues, a decrease in the amount of public debt, and with reverse processes.

Studying the possibility of using non-traditional vegetable raw materials of the Republic of Adygea in the production of functional antioxidant products

In the last decade the attitude of socially active people to their own health has changed significantly. The desire to lead a healthy lifestyle forms consumers’ demand for proper balanced nutrition, products enriched with natural biologically active substances of unconventional plant materials, systematic consumption of which can not only reduce the risk of alimentary diseases, but also protect a person from oxidative stress, which is the predecessor of many serious illnesses. Among the wide range of chemical compounds that make up plant materials, a special place is occupied by compounds of antioxidant action, such as flavonoids, phenol carboxylic acids, vitamins C and E. The aim of the research was to study the qualitative composition and quantitative content of natural antioxidants in some types of medicinal and technical plant materials of the Republic of Adygea to determine the possibility of their use in the production of functional food products. The content of biologically active compounds that determine the antioxidant properties of plant materials was determined using «Kapel 105 «M» capillary electrophoresis system and JASCO 875-UV liquid chromatograph. Antioxidant activity was measured by the amperometric method with Tsvet Yauza-01-AA analyzer. According to the results of the research, it has been found that Echinacea purpurea herb (1,09 g / dm3) and walnut leaves (0,96 g / dm3) exhibit a high antioxidant activity (in terms of gallic acid), which is due to the high concentration of natural antioxidants of the phenolic type. Due to these properties this plant raw materials can be used as enriching ingredients for the production of various groups of food products for functional purposes.
