Abstract. In this paper the catastrophic and extraordinary floods occurring in Barcelona County (Catalonia, NE Spain) are studied, in order to characterise the temporal evolution of extreme flash floods in that area and their main features. These events usually cause economical losses and major problems for undertaking daily activity in Barcelona city. This kind of floods is a very common feature in the North-east of Spain and they are recorded every year in some point of Catalonia. This contribution also shows the frequency of those events, within the framework of all the floods that have occurred in Barcelona since the 14th century, but also describes the flooded area, urban evolution, impacts and the weather conditions for any of most severe events. The evolution of flood occurrence shows the existence of oscillations in the earlier and later modern age periods that can be attributed to climatic variability, evolution of the perception threshold and changes in vulnerability. A great increase of vulnerability can be assumed for the period 1850-1900. The analysis of the time evolution for the Barcelona rainfall series (1854-2000) shows that no trend exists, although, due to the changes in urban planning, flash-floods impact has changed over this time. The number of catastrophic flash floods has diminished, although the extraordinary ones have increased.

The paper presents the results of the research on the growth, development, and biochemical evaluation of introduced Pyrethrum majus plants in the middle taiga subzone of the Komi Republic. It is established that in the conditions of culture the species is characterized by a high stability and winter hardiness. The phenology and dynamics of plant growth were studied. Morphological parameters of vegetative and generative shoots were determined. The yield of essential oil from the aboveground phytomass of P. majus and its component composition were studied. It was found that the content of essential oil of flowering plants varied over the years of research from 0,25 to 1,41% and depended on the weather conditions of the growing season. More than 190 components were found in the essential oil of P. majus plants using the method of GLC analysis, 48 of them were identified. The main terpenoids in the essential oil were S-(+) carvone (5465%), -tuyon (610%), TRANS-and CIS-p-Menta-2,8-dienols (2,32,8%), 1,8-Cineol (1,42,9%), CIS Menta-1(7)8-Dien-2ol (1,52,1%), germacrene d (1,21,8%) -cadinol (0,51,5%), -muurolol (0,22,6%). It was found that the component composition of the essential oil from perennial plants P. majus corresponds to the carvone-Tuyon chemotype and did not change significantly due to the meteorological conditions of the environment. Taking into account a high adaptation of plants of this species to the conditions of the middle taiga subzone of the Komi Republic, high indicators of aboveground phytomass with a sufficient content of essential oil, P. majus can be successfully cultivated in the North as a promising spicy-aromatic medicinal and ornamental plant.

Buckwheat is a valuable food crop. However, its low yield in comparison with other cereal crops leads to high prices for the cereal realization of this crop. Therefore, the development of techniques for increasing the buckwheat yield is relevant. One way to increase the buckwheat yield is to optimize the nutrition regime of the crop through the use of biologicals, macro- and microfertilizers. The researches devoted to the study of the complex application of biologicals and mineral fertilizers were being conducted during 2016‒2018 at the Institute of Agriculture of the North-East of the National Academy of Agrarian Sciences. The weather conditions of the growing seasons varied significantly over the years of research, which made it possible to study more fully the response of varieties to the factors studied. The studies were conducted in a three-factor field experiment where: - factor A ‒ the varieties of different morphotype; - factor B ‒ doses of mineral fertilizers (without fertilizers; N30P45K45; N30P45K45+N15; N16P16K16 in the rows; N16P16K16+N15) - factor C ‒ biological preparation Microgumine ‒ 200 g/ha; microfertilizer Reakom "Zernovyi" 0,5 l/ha; growth regulator Sodium humate ‒ 1.0 l/ha. According to the results of our research, it was found that Selianochka variety was better than Slobozhanka variety by responding to the use of seed inoculation and application of chelated fertilizer forms, with a yield increase of 0.05‒0.27 t/ha. With the increase of mineral nutrition, the yield increase was 0.01 t/ha less than in the Slobozhanka variety, namely from 0.06 to 0.45 t/ha. By Selyanochka variety, the variant with complex use of seed treatment with biological preparation, microfertilizers and application of growth regulator in the phase of "budding" of buckwheat plants, on the background of the use of mineral fertilizers at the rate of N16P16K16 + N15 the maximum yield of 2.20 t/ha was obtained. However, the yield increase after fertilizer application was 0.42 t/ha, from the use of biological products, microfertilizers and growth regulator ‒ 0.27 t/ha. In Slobozhanka variety, inoculation of seeds and application of chelated forms of fertilizers in the budding phase of plants also favoured to increase the yield, but not in all variants. On the other hand, the increase from the use of mineral fertilizers in all variants was positive from 0.04 to 0.41 t/ha. The comparison of the studied varieties of different morphotypes by yield showed that in Selyanochka variety it was of the average 1.96 t/ha during the research years, at fluctuations from 1.75 to 2.20 t/ha, by Slobozhanka variety ‒ 1.73 t/ha and 1.51‒1.92 t/ha respectively.

The article presents the results of 2016-2020 study of the characteristics of growth and development of the pannonian clover variety Snezhok, bred at the Federal Agricultural Research Center of the North-East named N.V. Rudnitsky, while using the herbage for seeds. Uneven-aged herbage was assessed in the breeding nursery of 2016 sowing according to the characteristics of winter hardiness, the duration of individual interphase periods of development, plant height, structure of seed herbage, fruiting and seed yield. The overwintering of plants in all the years of research was high ‒ 100%. With an increase in the age of the stand, the prefloral (from growing to the beginning of flowering) and growing seasons from 47 to 72 and from 92 to 125-130 days (days) were lengthened. The height of plants in the phase of maturation of heads and seeds with the age of the stand also increased from 66.6 (1 year of use (y.u.)) to 97.1 cm (4 y.u.), the tendency of herbage to lodging increased from 0 (1 y.u.) to 30.9% (4 y.u.). In the first year of seed use (the 2 nd year of life (y.l.)), the minimum values of such structural indicators as the number of stems and heads per 1 m2 (245 and 151 pcs.), The content of generative stems in the total amount (42.8%), weight of seeds per 1 m2 (15.3 g). Starting from the 2 nd y.u. the listed structure indicators significantly increased and herbage stands were formed annually for three years, allowing them to be classified as highly productive: with the stem density of 366-405 pcs / m2 and a share of generative ones in them - 59.0-84.2 %, the number of heads - 350 -500 pcs / m2 , seed weight - 31.5-46.1 g / m2 . The level of seed productivity of pannonian clover depended to a greater extent on the age of the stand than on weather conditions during the period from regrowth to seed ripening. It was revealed that the biological (potential) seed yield in favorable years with sufficient technical support can reach 4.33 c/ha, while the actual (economic) average over the years of research was 0.54 c/ha, with changes from 0.20 (2017) up to 0.74 c/ha (2020).

Elite varieties of black currant selected at the Federal Agrarian Scientific Centre of the North-East were studied with the purpose of identifying samples with an optimal combination of high productivity, large fruit, good taste, resistance to big bud mite and powdery mildew. The studies were carried out in 2015–2019 on a site located in the central agro-climatic zone of the Kirov region. 10 elite black currant varieties of 2013 planting were investigated. The varieties of Arkadiya and Vologda were used as control. The counts and observations were carried out using conventional methods. The combination of high productivity, its sustainability and high self-fertility was noted in varieties 71-2-07, 65-1-07 and 64-4-07. In terms of resistance to the pest, two highly resistant samples 71-2-07 and 65-1-07 were identified, which showed no signs of damage during the study period. The damage by big bud mite remained low across the entire experimental site. The average negative effect of big bud mite on the yield was found (r = -0.48). In the following 7 elite forms — 71-2-07, 65-1-07, 70-5-07, 46-1-07, 12-1-07, 15-1-07, 20-1-07 (70.0 % of the studied material), the maximum degree of damage by powdery mildew did not exceed 1.0 points, which indicates their high resistance. The combination of high resistance to big bud mites and resistance to powdery mildew was found in varieties 71-2-07 and 65-1-07. During the study period, 9 elite black currant varieties produced large-fruited berries. Out of these 9 forms, 3 (71-2-07, 64-4-07, 12-1-07) showed significantly higher values of this indicator compared to the Vologda control. Sample 27-1-07 was distinguished by a combination of large fruit, good taste and low acidity, as well as by high contents of ascorbic acid and dry matter. Sources of economically valuable traits were identified in 2 samples: 65-1-07 having a combination of high productivity, large fruit, high self-fertility, good taste, resistance to big bud mites and powdery mildew; 64-4-07 having a combination of high productivity, large fruit and high self-fertility. These genotypes can be recommended as a starting material for further breeding. On the basis of the results obtained, the Ariel variety (71-2-07) was forwarded to the State Variety Testing in 2020.

The paper discusses the influence of transportation costs on the delivery of liquefied natural gas (LNG) by sea. The research part of the project was carried out by using a dedicated LNG Moss type carrier with the capacity of 205,000 m3 and by taking into account the price of the propulsion engine fuel, LNG, as one of the most important factors of the final cost of LNG transportation. The fluctuation of the final costs also depends on the price of construction of a new vessel, the vessel’s design, sufficient number of the vessels required for transportation, and the amount of cargo to be shipped from a load port to the import terminal. The port of Murmansk, possibly one of Russia’s largest LNG load terminals, was used as port of departure, i.e. port of load. The final destinations, i.e. import terminals, included the ports of Zeebrugge, South Hook, Cove Point, Chiba and Fujian. It should be noticed that this study involved two sailing routes, the Suez Canal and the North East Passage, taking into consideration the harsh weather conditions the vessels might encounter during navigation.

The object of this research is the Russian historiography on his scientific biography. The goal a consists in the analysis of biographical essays, writings, newspaper notes about A. A. Chernov, available information on his scientific biography, as well as insufficiently studied topics. It is determined that the historiography of works dedicated to A. A. Chernov is extensive, and describes life path of the scholar, his academicc, pedagogical, and social activities. The author indicates Chernov’s role in training geology scholars in the process of institutionalization of science in the North, namely the Institute of Geology of Komi Scientific Center of Ural Branch of the Russian Academy of Sciences, organization of exploration works in the European North-East of Russia. His remarkable contribution to geological exploration of the territories of Russian North along with the discovery of Pechora coal basin is described. It is revealed that the history of establishment and development of Chernov’s scientific school, formed on the premises of Guerrier Courses in Moscow and in the Komi Branch of the Academy of Sciences of the Soviet Union remains insufficiently studied.
