Рассматривается один из основных ландшафтных кодов культурной географии – «вода/река», его анализ позволит понять особенности формирования хозяйственной специфики и духовных ценностей бродячих охотничье-рыболовных племен Восточной Сибири. Территории кочевания этих племен за последние 2 тыс. лет существенно сократились, и в настоящее время Нелемнинский наслег – земли родовой общины «Тэки Одулок» в Верхнеколымском улусе Республики Саха (Якутия) – единственное в своем роде место компактного проживания потомков древнего населения. Для северных кочевников юкагиров (охотников и рыболовов) вода/река имела культурообразующее значение: она кормила, помогала перемещаться с места на место, служила ориентиром на местности. Важность водных ресурсов рассматривается в статье через призму этнической истории юкагирского народа. Показано, что современная уникальная культура северных номадов Верхней Колымы сложилась благодаря двум основным факторам: сохранности гомогенной «кормящей» территории и незначительной трансформации традиционного годового хозяйственного цикла. Природно-климатические условия и полукочевой уклад жизни выработали у этой группы юкагиров устойчивые стереотипы мышления и поведения и определенную систему ценностей и предпочтений. Их пространственные представления формировались под влиянием ландшафта, в частности водной системы территории кочевания. Традиционно в период промысла родовые группы лесных юкагиров длительное время находились в изоляции – такое положение сохранялось вплоть до начала XX в. Подобные условия предполагали разного рода опасности и риски, реальные и воображаемые. При отсутствии дорог в теплое время года и в силу большой заболоченности территории древний ландшафтный код «вода/река» определял номадический характер культуры юкагиров. Водная система в представлениях охотников и рыболовов Верхней Колымы запечатлена в духовной и материальной культуре как амбивалентная стихия. В геокультурном пространстве потомков аборигенных северных номадов концепт «водная стихия» традиционно построен на культурных смыслах, образах и символах. Сегодня присваивающий характер хозяйства лесных юкагиров и сохранение значимости ландшафтного кода «вода/река» позволяют говорить, что в обозримом будущем в культуре этого народа по-прежнему будут присутствовать элементы древних языческих религиозно-мифологических представлений. The article considers one of the main landscape codes of cultural geography – water/river, which in part determined the specifics of economy and spiritual values of the wandering hunting tribes of Eastern Siberia. The areas of nomadic hunting and fishing tribes of Eastern Siberia have significantly decreased over the past two thousand years, and currently the territory of the Nelemninsky National Council and the tribal community “Teki Odulok” in the Verkhnekolymsky region (ulus) of the Republic of Sakha (Yakutia) is the only place of compact residence of descendants of the ancient population. Among the northern nomads –Yukagirs-hunters and fishermen, the water/river landscape code was of a cultural-forming significance; water/river provided food, transport and served as a reference point in space. The significance of water resources is considered in diachronic and synchronous ranges against the background of the ethnic history of the Yukagir people with the involvement of archival and literary data. It is shown that the modern functioning of the unique culture of northern nomad dog breeders in the Upper Kolyma is due to the preservation of a homogeneous feeding territory and a minor transformation of the traditional annual economic cycle. The territorial community, the organization of living space in such climatic conditions and the semi-nomadic way of life have developed stable stereotypes of thinking and behavior, a system of values and preferences for this group of Yukagirs. The understanding of space of the nomad dog breeders reveals the mechanisms of formation and influence of the water/river discourse on various aspects of their activities. Traditionally from antiquity and to the beginning of the 20th century during the period of fishing and nomading on boats and rafts in the warm season, the tribal groups of forest Yukagirs were isolated for a long time. This situation implied various potential dangers and risks, real and mythologized. The ancient landscape code water / river in the absence of dirt roads in the warm season and a large bog area determined the nomadic nature of the culture. The figurative and geographical model of the water universe at the locus of the water hunters and fishermen of the Upper Kolyma is captured in the discourse of spiritual and material culture as an ambivalent element. In the geo-cultural area of the descendants of the aboriginal northern nomads, the concept of the water element is traditionally built on cultural meanings, images and symbols. The appropriating nature of the economy and the longstanding significance of one of the main landscape codes of water/river stimulate the continued exsistence of ancient pagan religious and mythological representations among the forest Yukagirs in the foreseeable future

A growth in the number of deer and an increase in their productivity are closely related to the solution of the complex problem of reproduction and rational use of deer females. Significant damage to reindeer husbandry is caused by the barrenness of northern domestic deer, the level of which has been quite high in recent years. So, in the Republic of Sakha, on 01.01.2020, the number of domesticated reindeer was 152,068, of which female deer and heifers — 71,818, offspring per 100 females — 59, business yield amounted to 52 fawns per 100 females. The causes of infertility are very diverse, as the natural and climatic conditions of the breeding zones have a significant influence on the reproductive function of reindeer. In Yakutia, the main population of northern domestic deer is bred in mountain taiga and tundra natural-climatic zones, so there are about 55 thousand deer in the mountain taiga zone and more than 65 thousand deer in the tundra zone. In this regard, the study of the peculiarities of the postpartum period course in domestic reindeer females, its morphophysiology, and behavioral reactions depending on the natural and climatic conditions of breeding is of great importance.

The article notes that the growing popularity of healthy lifestyles contributes to the increase in consumption of fruits and berries. At the same time, the analysis of the dynamics of the gardening industry for 2000-2018 shows that the problem of providing fresh fruits and berries to the population remains one of the most important. Based on actual data, linear and logarithmic models of time series of key industry indicators for the period 2010 – 2019 have been compiled. Calculations showed that in the Russian Federation as a whole the trend of reduction of sown areas of perennial fruit plantations will continue with growth of yield and gross fees. In this regard, the issues of distribution and introduction of gardens of intensive type are updated. An overview of the views of domestic scientists-gardeners on the concept of “intensive garden” is given. It has been established that the distribution of intensive gardens is possible only if there are favorable natural and climatic conditions and a developed scientific and production base of nursery management. The current state and problems of gardening in one of the leading regions – the Republic of Dagestan - are considered. A significant technological lag of region in the further development of intensive horticulture has been identified. Various directions of intensification process in horticulture as the main and necessary condition of growth of efficient and sustainable production are summarized.

The Impact

In the Russian Federation logging operations are traditionally carried out in winter. This is due to the predominance of areas with swamped and water-logged (class III and IV) soils in the forest fund, where work of forestry equipment is difficult, and sometimes impossible in the warm season. The work of logging companies in the forests of the cryolithozone, characterized by a sharply continental climate, with severe frosts in winter, is hampered by the fact that forest machines are not recommended to operate at temperatures below –40 °C due to the high probability of breaking of metal structures and hydraulic system. At the same time, in the warm season, most of the cutting areas on cryosolic soils become difficult to pass for heavy forest machines. It turns out that the convenient period for logging in the forests of the cryolithozone is quite small. This results in the need of work in the so-called off-season period, when the air temperature becomes positive, and the thawing processes of the soil top layer begin. The same applies to the logging companies not operating in the conditions of cryosolic soils, for instance, in the Leningrad, Novgorod, Pskov, Vologda regions, etc. The observed climate warming has led to a significant reduction in the sustained period of winter logging. Frequent temperature transitions around 0 °C in winter, autumn and spring necessitate to work during the off-season too, while cutting areas thaw. In bad seasonal and climatic conditions, which primarily include off-season periods in general and permafrost in particular, it is very difficult to take into account in mathematical models features of soil freezing and thawing and their effect on the destruction nature. The article shows that the development of long-term predictive models of indicators of cyclic interaction between the skidding system and forest soil in adverse climatic conditions of off-season logging operations in order to improve their reliability requires rapid adjustment of the calculated parameters based on the actual experimental data at a given step of the cycles.

The Republic of Croatia has a long tradition of fruit growing due to its geographical location, climatic conditions, and high quality of fruit crops, especially apple fruits. Apples can be used for the formulation of functional foods either in processed form (e.g., juice), or as a by-product (e.g., apple pomace). However, there is a growing demand for functional foods derived from ancient and traditional plant sources as they are recognized as a very valuable source of health-promoting bioactive ingredients. Similarly, old apple cultivars (Malus domestica Borkh.) are characterized by good morphological and pomological properties, less need for chemicals during cultivation and the higher share of biologically active compounds (BACs) with better sensory acceptability compared to commercial cultivars. However, their nutritional and biological potential is underestimated, as is their ability to be processed into functional food. The importance in preserving old apple cultivars can also be seen in their significance for improving the nutritional composition of other apple cultivars through innovative cultivation strategies, and therefore old local apple cultivars could be of great importance in future breeding programs.

This paper presents a computational tool for estimating energy generated by low-power photovoltaic systems based on the specific conditions of the study region since the characteristic energy equation can be obtained considering the main climatological factors affecting these systems in terms of the symmetry or skewness of the random distribution of the generated energy. Furthermore, this paper is aimed at determining any correlation that exists between meteorological variables with respect to the energy generated by 5-kW solar systems in the specific climatic conditions of the Republic of Cuba. The paper also presents the results of the influence of each climate factor on the distribution symmetry of the generated energy of the solar system. Studying symmetry in statistical models is important because they allow us to establish the degree of symmetry (or skewness), which is the probability distribution of a random variable, without having to make a graphical representation of it. Statistical skewness reports the degree to which observations are distributed evenly and proportionally above and below the center (highest) point of the distribution. In the case when the mentioned distribution is balanced, it is called symmetric.

This article represents the results of a study of changes in the properties of vulcanizates based on BNR-18 butadiene-nitrile rubber containing as stabilizers the experimental spatially hindered phenols Stafen, CO3, CO4, and industrial antioxidant 6PPD, after accelerated aging (100°C 96 h) and aging under full-scale exposure in extreme climatic conditions of the Republic of Sakha (Yakutia) during 2 years. In winter, the air temperature reached—48°C, in summer—+36.1°C. It is shown that the experimental sterically hindered phenols more effectively under natural exposure conditions. They are characterized by the most stability in terms of strength throughout the entire exposure period. Under conditions of accelerated aging, the vulcanizate containing the industrial antioxidant 6PPD is characterized by the greatest stability of physical and mechanical properties. According to the viscoelastic characteristics obtained in the dynamic loading mode, the contribution of the presented stabilizers in maintaining resistance to temperature and deformation effects compared with unstabilized rubber is confirmed.

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.

The paper presents the results of evaluating the efficiency of feed rations offered to broilers of the Arbor Acres cross, formed taking into account the climatic, geochemical conditions of Central Africa and its native food flora. The study was conducted on the basis of an experimental farm at the University of N’Djamena, the Republic of Chad. In the experiment, the authors used five formulas of feed rations, which are currently used by farms in the Republic of Chad for growing broiler chickens. They mainly contain locally availble ingredients. To increase the resistance of the poultry organism to unfavorable environmental factors, the chickens of the control and experimental groups were given “TETRACOLIVIT” and “AMIN’TOTAL” vitamins. The efficiency of feed rations was evaluated by determining the age dynamics of live weight, average weekly gains in live weight and blood biochemical parameters of broiler chickens of the Arbor Acres cross from 1 to 42 days of life. The formula of feed ration No. 1 proved to be the most effective in terms of the cross productivity.

The Republic

The Republic of Tyva is a region in the geographical center of Asia, which located at the junction of the Siberian taiga and Central Asian desert-steppe landscapes, in a wide band of mountains and intermountain plains. The mountain-forest area of Tyva has long been considered a natural habitat for antler deer, one of which is the maral (Cervus elaphus sibiricus). In order to restore maral breeding and increase the number of marals in the former limits, marals of the Altai-Sayan breed have been imported to the Republic of Tyva from the Republic of Altai. The preservation of productive traits, reproductive function and the realization of the genetic potential of animals introduced to new climatic conditions largely depends on the ability of these animals to adapt to existing environments. We have assessed in this paper the natural resistance of the marals of Altai-Sayan breed during introduction in the Tyva Republic in comparison with the indicators of the marals have been bred in the Altai Republic. The researches have been carried out in 2019. The research material was blood samples of marals of Altai-Sayan breed imported to the Republic of Tuva (n=27) and marals of the same breed bred in the Republic of Altai (n=17). Studies have shown some deviations in the blood leukogram of imported marals, such as a decrease in the number of eosinophils and rod nuclear neutrophils (P < 0,001), the increase in the number of segmented nuclear neutrophils and lymphocytes (P < 0,05). The number of monocytes have been increased in 18,6 times compared to the Altai marals. The change in the number of monocytes exceeded the physiological norm by 24,7 %. The indicator of adaptation evaluation in imported marals had higher values (6,8), which were in 1,7 times higher than in marals bred in the Altai Republic (4,1), which indicates the intensity of adaptive mechanisms in imported animals during adaptation. Analysis of phagocytic activity and phagocytic index revealed intensive phagocytosis in imported marals: phagocytic activity – by 12,4 % (P < 0,05), phagocytic index – by 5,1 %, and the increase in the content of lysosomal and cationic proteins by 12,8 % (P < 0,05). Analysis of the bactericidal activity of blood serum has shown its lower level in imported animals (45,97±1,36 %), compared with marals of the same breed bred in the Altai Republic (52,19±2,15 at P < 0,05). Thus, according to most indicators of natural resistance marals of Altai-Sayan breed imported to Tyva have a fairly high level of natural protection, which indicates that they can be adapted to the natural climatic and feeding conditions of the Republic of Tyva.
