The positive trends in climate change that have become apparent in recent decades are accompanied by a shift in the range boundaries of many boreal plant species further north, to the shores of the Arctic Ocean. Monitoring the displacement of these boundaries, the introduction of plants unusual to the Arctic, as well as monitoring their adaptation to new conditions, is an important component of botanical research. In 2016, in the village Tiksi identified 2 species of woody plants - Betula pubescens and Salix udensis, known from the forest zone and not previously observed in this area. Obviously, both species appeared here due to the unintentional introduction of seeds by humans. Repeated observations of the condition of these species, conducted in 2023, showed that they exhibit stable vitality, withstood 7 winter periods and gave some increase in phytomass. Measurements of the area of the leaf blade of Betula pubescens and the size of 10 leaves of Salix udensis showed that these indicators are within the normal biological parameters of these species. Both species do not form generative structures yet. Salix udensis has grown significantly during the observation period, reaching a height of about 2.5 m. Perhaps this is the result of the protective influence of the building behind which it develops. Betula pubescens grows more slowly, hardly retains orthotropic shoots exceeding the average snow cover levels, which reach a height of 54 cm, but at the same time partially drained and deprived of foliage. Nevertheless, the lower part of the plant has fully leafy branches. Both species are valuable objects for further observations of their adaptation to Arctic conditions. Since Betula pubescens grows near the slope of the highway, it is recommended to move it to a safe place less susceptible to anthropogenic influence. Tiksi village, located in high latitudes, could serve as a good reference base for a wide range of scientific observations of plant adaptation to Arctic conditions. The optimal solution for this would be the creation of the Arctic Botanical Garden in Tiksi.

The work examines a technological solution to the issue of preserving and popularizing the cultural heritage of the Arctic through the creation of virtual tours. The stages of developing a virtual tour are presented using the example of the “Kingdom of Permafrost” complex as a model for the use of virtual technologies in real practice.

The article presents the results of a comparative analysis of literature data on the chemical and fatty acid composition of cow's milk and milk of Yakutian cattle. It was found that the milk of Yakutian cattle had a higher content of dry substances, including a mass fraction of fat up to 6%. According to analysis of the fatty acid composition milk fat of Yakutian cattle is fully composed, contains a large amount of vital linoleic, linolenic and arachidonic fatty acids. The article also provides data on the chemical composition of Honguri zeolite, which contains all essential trace elements. In addition, the authors revealed a wide use of zeolite as an unconventional feed additive to livestock feed and its positive effect on their bioelement balance and feed digestibility. On the above basis, the authors put forward a hypothesis about the possibility of using zeolite for heating oil during plasma deposition. Studies of the dynamics of acid and peroxide numbers indicate the ability of zeolite to adsorb oxidation products and free fatty acids contained in ghee. Data on the dynamics of the acid and peroxide number of ghee for 30 days at 3+2 0С in a polymer opaque leaky package are presented.

The article deals with the task of text processing using neural networks to determine authorship. The relevance of this topic is due to the increasing role of artificial intelligence in various fields, including natural language processing. A practical example of implementation of neural network approach to text authorship determination using Keras Python library on Google Colaboratory platform is presented. The steps of data preparation, creation of training and test samples, model building and training are described. The obtained results demonstrate high accuracy of text authorship identification, reaching 95-98%.
