Synthesis of As2Se3 in organic medium
Статья научная
Arsenic (III) selenide has been synthesized in organic medium by using metaarsenite and amorphous selenium. The synthesis was carried out at the temperature range of 433-443 °K, pH >10, during 2-8 hours. Resulting sediment is filtered, washed at first by 0.1 M of acetate acid solution, then by ethyl alcohol and dried at 353 °K. The chemical analysis of the sediment is made, thermal, X-ray phase analyses are carried out, and electron microscope images of microparticles are taken.

Synthesis of amides and salts of oxalic acid and their use as plant growth regulators
Статья научная
Oxalic acid plays a very important role in the life of plant organisms. In addition, its salts and amide derivatives also have growth-stimulating properties. In this work, we show the results of research in the field of synthesis of amide derivatives of oxalic acid, and also investigated their growth properties using the example of some agricultural crops. Have found that the mono amide of oxalic acid has a stronger effect on the growth of pea seeds compared to the disubstituted amide of this acid. Thus, we can conclude that salts and amide derivatives of oxalic acid have a pronounced regulatory property during the ripening of pea and corn seeds. In this regard, they have been recommended as growth stimulants for these plants in agricultural practice.

System of ensuring social and economic security of the industrial sector
Статья научная
The methodological basis for the formation of the system of ensuring socio-economic security includes features of the industrial sector. The specifics of his defense was designed to show with the help of the methodological and operational foundations. Methodological framework is formulated based on the research process the functional specificity provide socio-economic security of the industrial sector. They form the perimeter of ensuring social and economic security, which is formed by the expectations of society from the defense system of the industrial sector of the country. Operating bases are complementary to the functional specificity of the system provide socio-economic security by means of the formation of a specific institutional framework. Among them, the following are noted: modeling, allowing multivariate escalation of adverse events in the industrial sector and methods of its evaluation; instrumental assistance, taking into account the need for instrumental diversity for the implementation of defense functions in changing criteria (the environment of the industrial sector, its structure and the state of inter-element connections); functional coherence as the need to balance the goals of ensuring the socio-economic security of the industrial sector with the objectives and values of the formation of the industrial sector of the country, which are fixed in the policy documents of the state.

Systematic review of the genus Hypericum L. in flora of Azerbaijan
Статья обзорная
Among the widespread plant species in Azerbaijan, the genus Hypericum L. which dates back to the Cenozoic era and belongs to the family Hypericaceae takes special place. 80% of the total number of species belonging to the Hypericaceae family are concentrated in the genus Hypericum , which is distinguished by its many-sided areas of application, especially in the pharmaceutical, decorative and dye industries. This genus is considered one of the largest genera of flowering plants in terms of species diversity (22%). Although research on the systematics of the genus Hypericum has been conducted by many scientists around the world, the general characteristics and taxonomic composition of the species distributed in the flora of Azerbaijan have not been studied for the last 50 years. As a result of our research, it was determined that there are not 15 species, but 19 species, 1 subspecies and 1 variety belonging to the genus in the flora. The characteristics, descriptions and synonyms of sections, species, subspecies were given.

Taboos in Kyrgyz, Russian and English
Статья научная
This work explores the concept of taboos, their role in society, and their variations across different cultures. Taboos are social, cultural, and religious prohibitions that regulate behavior and communication. While some taboos maintain order and preserve traditions, others may seem outdated or restrictive. The study focuses on taboos in Kyrgyz, Russian, and English, analyzing their differences and significance. In Kyrgyzstan, taboos emphasize respect for elders, family honor, and religious beliefs. In Russia, many taboos are linked to superstition and politics, while in Great Britain, they are mostly related to politeness and personal boundaries. The paper also discusses the evolution of taboos, highlighting how societal changes influence their relevance. The analysis concludes that while taboos play an important role in shaping cultural identity, they should be reconsidered when they limit personal freedom or hinder progress. Understanding taboos helps improve cross-cultural communication and promotes tolerance.

Research was conducted to study the parasite fauna of sheep in the Guba-Khachmaz economic region of Azerbaijan and the species composition of pathogenic parasites causing a decrease in productivity and mortality of animals was determined. The nematode fauna of sheep in the Guba-Khachmaz economic region consisted of 22 species, the trematode fauna consisted of 4, and the cestode fauna consisted of 5 species. Among the primary blood parasites found in sheep are Anaplasma ovis, which belongs to the Rickettsiales order, and Babesia ovis, Theileria ovis, Th.recondita, which belong to the Piroplasmida order. During the study period, 4337 sheep were examined for helminths in the economic region using the complete and incomplete dissection methods. In 3560 of 4337 sheep, was noted associative invasion by nematodes, cestodes and trematodes (I.E. - 82.1%). Infection with nematodes was accompanied by weight loss and a decrease in the quality of wool in sheep, and intensive invasion with fasciola led to the death of young animals, mainly lambs. Intensive infection of sheep with monieziasis was accompanied by a decrease in appetite and milk yield, weight loss. To determine associative ınvasion of sheep with helminths and primary blood parasites, were examined peripheral blood smears and fecal samples from 3435 animals. Of 3435 samples in 1996, were found to have associative invasion with primary blood parasites and helminths (I.E.-58.1%). Mortality has been reported in lambs under 1 year of age, especially 4-5 months old, associated with primary blood parasites and helminth infections. Ectoparasitic ixodid ticks, which transmit primary blood parasites that parasitize animals in the Guba-Khachmaz economic region, are classified into 2 genera, consisting of 4 species.
