Within early warning and technological hazards, the need to notify, and to identify, assess and provide the necessary information about the sources of potential hazards is of particular importance. Since there may be causal links between natural and technological disasters, there are increasing concerns that the available knowledge base does not allow for timely warning or relief measures for many hazards. Any early warning system aims to reduce risk as a measure of potential environmental and economic damage. Such reduction, as a rule, is achieved by continuous study of information on the state of functioning of the natural-technical system. Hence the task of systematic collection, accumulation, processing and analysis of information arises. The system of continuous observation, control and analysis of the environmental situation for subsequent diagnosis and forecasting of the state of natural objects is realized within the framework of monitoring, which is performed at three levels - global (planetary), regional and local. The Sakha Republic (Yakutia) is the largest region of the Russian Federation with a highly concentrated natural-resource potential, providing full-scale projects of national economic development of interregional and federal signi cance. Yakutia, the area of which is 20 % of Russia’s territory, is a giant natural enclave in geotechnical terms, the administrative boundaries of which cross many geographically heterogeneous ecosystems of seven neighboring territories (administratively independent subjects of ownership). The article considers and reveals the main directions of the early warning system to prevent socio-natural risk as applied to Yakutia, taking into account its natural-territorial uniqueness.

The article considers rational schemes for cutting the tracks of linear objects using felling-skidding-processing machines. A comparative analysis with modern, most common technological processes of cutting tracks of linear objects is carried out. Based on the analysis of literary sources and production experience in the field of logging, the possibility of using these machines is justified not only according to the classical scheme, but also, if necessary, in the roll-packing mode, with the involvement of an additional skidding tractor. The work was carried out within the framework of the scientific school "Innovative developments in the field of logging industry and forestry" of the Arctic State Agrotechnological University.

The article analyzes an approach to modeling the mechanism of grabbing and dragging the harvester head in the process of pruning branches of coniferous and deciduous trees of complex shapes in various natural and industrial conditions. The type of trees under consideration differs in different geometric shapes of trunks and shapes of branch sizes. The presented modern grabbing, cutting and bucking devices (harvester heads) are not effective enough for processing such trees in various conditions. To solve these problems, head design projects are required that meet the tasks set. To do this, it is necessary to simulate the process based on the original tree models with realistic geometry. The main designs of harvester heads have original derivative models that perform basic functions such as feeding the barrel using a feeding mechanism and cutting branches with grab knives. These models, identified experimentally, make it possible to predict well the interactions between different parts of the block and trees. The simulation results are in good agreement with the observed behavior of the actual operation of the system and represent a design support tool for the development of innovative concepts of harvester blocks. At this stage, there is a need to simulate and analyze two types of feeding mechanisms when pruning branches. The feeding mechanism of the roller harvester head and the pulse type head. The work was carried out within the framework of the scientific school "Innovative developments in the field of logging industry and forestry" of the Arctic State Agrotechnological University.

The article presents the results of a patent and information search for developments on the industrial technology of the Japanese dessert mochi. The data search was carried out in the search system of the Federal Institute of Industrial Property, the international database of the latest publications “Google-scholar”, the domestic electronic library database Elibrary.ru, and the Google search engine. The work was carried out in the process of studying the discipline “Theoretical foundations of scientific research work” in the direction of training 04/19/03 “Food products of animal origin” profile “Technology of dairy products”. As a result of our research, we obtained useful information about the production technology of the Japanese dessert mochi, the recipe for the production of dough and filling based on curd cheese. It has been established that the filling of mochi determines its taste properties. Traditionally, beans, sweet potatoes, fruits and nuts are used as filling. At the same time, traditional cakes do not contain flavoring fillers or sweeteners. However, in other countries, to adapt to market needs, the filling recipe is supplemented with flavoring components: coffee, vanilla, etc. In addition, data was obtained on the technological properties of rice necessary for the production of mochi. It has been established that the stickiness of rice, which determines the required consistency of the dough, depends on the amylose content in it. The data obtained allow us to determine further prospects and tasks of our research work.

The negative adverse effects of intensive agricultural production on food safety and the environment are presented. It has been substantiated that the use of microbial inoculants in plant growing is a viable alternative to traditional industrial technologies based on the use of agrochemicals such as pesticides, inorganic fertilizers, herbicides, etc. and leading to destructive effects on human health due to the consumption of unsafe food. The classification of microbial inoculants for seed treatment according to functional characteristics has been developed. It has been established that in the seed treatment with biological preparations, the most common method is treatment with microbial inoculants containing nodule bacteria. The list of biopreparations used in practice for plant protection is presented, as well as the main characteristics of methods for applying them to seed. It has been determined that the technological effectiveness of seed treatment with microbial inoculants depends on many factors that ensure the survival of microorganisms during seed processing and storage, the dominant ones being the formulation of the inoculant, as well as its ability to multiply in the spermosphere, infect the root system, and in some cases, the rhizosphere of plants.

This article provides a brief overview of the study of sorghum-Sudanese hybrid in the natural and climatic conditions of Yakutia. It is a forage crop developed by crossing sorghum with sudangrass. It is cultivated mainly in the central regions of Russia. Direct interest in this crop is associated with its high productivity and high nutritional values. So it is characterized by a high content of fiber, protein, vitamins and minerals. Therefore, the hybrid sorghum-sudang plant is an ideal food for animals, providing them with the necessary set of nutrients for health and high productivity. In addition, the sorghum-sudang hybrid is resistant to various diseases and pests, which reduces the risk of crop losses and facilitates the growing process. However, depending on the natural and climatic conditions of cultivation, any crop can change its quality indicators in one direction or another. In this regard, the study of cultivation and the influence of sowing time of sorghum-sudan hybrid and its mixtures on green mass in the conditions of Central Yakutia is a very urgent problem. In the conditions of Yakutia, we will study the biological features of the growth, development and yield formation of the sorghum-Sudan hybrid and its mixtures for green mass in the conditions of Central Yakutia (corn, sunflower, millet, Sudan grass, oilseed radish, spring rape, spring vetch, field pea, oats). The optimal timing of the sorghum-Sudanese hybrid and its mixtures for green mass will also be established, and the agro-energy assessment and economic efficiency of the sorghum-Sudanese hybrid and its mixtures for green mass will be determined.

Wild plants occupy an important place in the lives of many people, especially in Yakutia. These plants serve as a unique strategic resource and food product, and contribute to maintaining health. Natural gifts such as berries, nuts and mushrooms obtained from forests contain a high concentration of vitamins, minerals and beneficial properties. They are the most important basis for ensuring the lives of many residents living in remote areas of Yakutia, and serve as a source of income. The gathering, processing and sale of forest products has become a profitable business. The article reviews various aspects of the topic of wild berries in the context of mass media. The authors study the data to determine the frequency of news on this topic and their nature. As part of the study, the results of a sociological survey conducted among the population of the Republic of Sakha (Yakutia) were analyzed in order to find out which family members are engaged in berry picking and what are the ways of their access to the collection sites. The purpose of the study was to identify the key features of the coverage of this topic in the news. The results obtained can be used to develop strategies for the conservation and sustainable use of forest resources in Yakutia. This may involve supporting the development of local businesses related to the collection, processing and sale of forest products, as well as creating conditions for the conservation and use of forest areas on a long-term basis.

The importance of studying the microelement composition of soils and vegetation in the Northern territories is due to the role of microelements in soil formation under cryolithozone conditions, and secondly, the influence of the microelement background of plants on the physiological functions of animals and humans. At the same time, heavy metals deserve special attention as they pose a threat to all living organisms due to their ability to accumulate. The article presents data on the content of heavy metals in the aboveground parts of meadow grasses growing under cryolithozone conditions - in the Khangalassky district, located in the Central Yakut biogeochemical province. Atomic absorption spectral analysis showed that the content of heavy metals - cadmium and lead - in the aboveground parts of the studied plants varied significantly depending on the place of collection, but did not exceed the maximum permissible concentrations. The concentration of zinc in some of the herbal collection points exceeded the maximum permissible concentrations. The need to study the content of heavy metals in plants is due to the fact that they are the primary link in the movement of toxic elements along the trophic chain into the human body. Lead and cadmium accumulate in parenchymal organs, are carcinogenic and affect the morbidity and mortality of the northern population.

Determining the variability of the proportions of the human body living in extreme climatic and geographical conditions of the North is relevant for understanding the topography of internal organs, the ratio of body components, and the proportionality of the body surface to body weight. In Yakutia, there are not enough scientific papers on body proportions, which determined the relevance of this work. The aim of the work was to identify the ethnic and gender characteristics of the body proportions of Yakutian students. A total of 314 girls aged 16-20 and 156 boys aged 17-21 of Yakut ethnicity were examined. Somatometric examination was carried out according to the method of V.V. Bunak, with the determination of body length and body weight. The diameter of the shoulders, the diameter of the pelvis, the transverse diameter of the chest and the anterior-posterior diameter of the chest were measured. The following heights were determined on the upper limb: acromial, radial, styloid and finger point. The trochanter, upper tibial height and lower tibial point were measured on the lower limb. An index assessment of physical development was carried out (index of relative width of shoulders, pelvis, index of arm and leg length, pelvic-shoulder index, Brugsch index). Statistical processing was performed using the SPSS application software package for Windows (version 22.0). Parametric and nonparametric methods of statistical analysis were applied. Gender differences in all studied anthropometric parameters among the Yakuts were established. Indicators of body length and weight, arm index, leg index, index of relative shoulder width in the boys were significantly higher than the parameters of the girls. The index of the relative width of the pelvis and the pelvic index were significantly higher in girls. According to the index of relative pelvic width, metriopyelia was significantly more often registered among the girls, and stenopyelia among the boys. The predominant body shape for the girls was a rectangular shape, for the boys - the average body shape. Ethnic characteristics were expressed in lower body length, shoulder diameter and leg length in Yakut girls compared to Russian girls living in Yakutia. In boys, among the compared parameters, the ethnic difference is observed only in the parameter of shoulder diameter, which was significantly smaller in Yakut boys.
