Large forested areas, small slopes of catchments, the presence of lakes and swamps, the karstification of the basin, and a large share of underground river feeding contribute to a decrease in the amount of sediment runoff in the rivers located in the North-West of Russia. The distribution of sediment runoff during the year is determined by the flow regime of the river. The maximum values of the monthly solid runoff modules of all the studied rivers are observed at high water in March – May, usually reaching the peak in April, which is typical for the north-western region. Moreover, the passage of the maximum for the northern rivers (Pasha, Oyat and Tikhvinka) mainly falls on April – May; for rivers flowing in the southern part of the region – on March – April. The minimum values of the annual runoff modulus in the low-water period are extremely insignificant, especially in winter, and for some years they are close to zero. This is quite understandable due to the significant contribution of soil erosion to the formation of solid runoff of watercourses, with the most intensive processes of soil erosion occurring during the period of active snowmelt and floods. A steady increase in air temperature and precipitation layers for the North-West of the Russian Federation in the last thirty years in comparison with the previous climatic period has led to an increase in the river runoff for the studied watercourses. At the same time, according to the observations for the selected climatic periods, there is a decrease in the annual solid runoff. This can be explained by socio-economic changes – a significant decrease in agricultural activity in the region. In addition, taking into account the increase in the water content of the rivers, the decrease in the solid runoff can be explained by the redistribution of the intra-annual course of meteorological values that occurred as a result of climatic changes.

The article deals with the assessment of the prospects of the political future by representatives of Russian youth. The text of the article has been prepared within the framework of the project “Potential of Youth Political Leadership in The Course of Political Socialization and Circulation of Elites in the Russia Regions in the 2010s (using the example of South-Western Siberia and the North-West of the Russian Federation), RFBR grant No. 18-011-01184. The relevance of the research is in combining a fundamental review of the main directions of research of the role of youth participation in the social and political process and the involvement of a specific empirical study conducted in the spring of 2019, which allows highlighting various aspects of the situation. The empirical part of the study is based on the study “Ideas of Youth about Possibilities of Youth Leaders and Youth Organizations in Russia”, which was conducted in spring 2019 in four constituent entities of the Russian Federation — Altai Territory, Leningrad and Novosibirsk Regions and St. Petersburg. The method of research was a personal standardized interview, the sample size was 1000 respondents (250 in each of the regions), representatives of young people aged 14 to 30 permanently reside in the territory of the studied subjects of the federation. Based on factor and cluster analyzes, the main models of expectations of the political future are presented. The article should be of interest to researchers, both professionally involved, and simply interested in the topic of the influence of the real political process on such a significant group of the population as youth.

Long-term complex observations covering the period of 1949–2018 made possible to determine the average annual characteristics of the depth of freezing of wetlands in the North and Northwest of the European territory of Russia together with main factors of its formation, and spatial and temporal variability. The main factors that determine the depth of freezing of wetlands are ambient temperature, snow cover thickness, and a degree of watering of the micro landscape (water reserves of the micro landscape). At the initial stage of freezing, the major factor is the ambient temperature, when intensity of the freezing reaches 0.5–0.8 cm/day. As snow falls, the freezing rate becomes smaller, and when the snow cover thickness reaches 25–30 cm the depth amounts to 0.2–0.3 cm/day and smaller. It was found that the spatial variability of the freezing depth decreases from large values of the coefficient of variation (0.3–0.4) at the depth of 20–30 cm to less than 0.1 when the depth exceeds 60 cm. The largest values of the depth are recorded in the North of the Kola Peninsula, where sometimes they reach from 84 to 97 cm with the average values of 48–66. In large hummocky bogs, when the seasonal freezing comes down to 63–65 cm it links with the permafrost layer. On average, swamps of these bogs freeze down to a depth of 68 cm. The average climatic depth of freezing of oligotrophic bogs of the NorthWest is 21–24 cm; in some years, freezing of them reaches 32–40 cm. It has been shown that the relative warming of the climate resulted in decreasing in the depth of freezing of wetlands in the North and North-West of the European territory of Russia. Relative to the previous climatic period, the depth of frost penetration in the northern Ilasskoye bog decreased by 32%, and in north-western Lammin-Suo bog – by 31%.

Abstract Mastitis in cows in the farms of the Russian Federation cause great economic damage. Economic losses include the cost of treating cows and the cost of recycled milk. In the farms of the North-West region of the Russian Federation mastitis occurs in 20–30% of lactating cows. An important task is to find effective ways to prevent mastitis. The task of our research included the study of the effectiveness of external use of staphylococcal toxoid. For the experiment, 2 experimental groups of dry cows of 10 animals each were formed. For the first group of cows, 5 days before the expected date of calving, an ointment containing staphylococcal toxoid and dimethyl sulfoxide was applied to the area of the milk mirror. Udder treatment was performed once a day for five days. Cows of the second group were immunized with Starvac® vaccine in accordance with the instructions, twice during the dry period. The third group of cows (n = 20) was the control. After calving, the concentration of immunoglobulins in colostrum was examined in all cows. In cows of the first group, the concentration of immunoglobulins G, M and A in colostrum was 8.59 ± 0.9; 1.1 ± 0.13 and 5.42 ± 0.9 g / l, respectively. The concentration of immunoglobulins in cows of the first group was higher, on average, by 1.3–2.0 times in comparison with cows that were given the Starvac vaccine. In comparison with the control group, the growth of all classes of immunoglobulins was determined by 2.2 - 5.2 times (P < 0.01). The results obtained showed high efficacy of external use of staphylococcal toxoid together with dimethisulfoxide.
