Physical and social spaces interactions: rural-urban dynamics in new constructions in Kyrgyzstan
Статья научная
In Kyrgyzstan’s evolving cultural landscape in post-Soviet time, rural and urban dynamics reveal a captivating story of adaptation. This study explores domestic spaces, specifically the ‘bathhouse’, ‘naves’, and toilet placement preferences in newly built houses. The traditional rural ‘bathhouse’ has ventured into urban settings, challenging established notions. Conversely, the urban ‘naves’ now thrive in remote rural areas, reflecting evolving cultural tastes. Toilet placement choices among new settlement residents exemplify the fusion of rural and urban influences, highlighting their ability to adapt rural culture to urban living. This research underscores Kyrgyzstan’s complex cultural identity, where tradition and modernity harmonize, transcending urban and rural boundaries.

Physiological characteristics study of normalization of carbohydrates in food rations
Статья научная
Carbohydrates are organic substances with high energy, enter the body with food and satisfy the various needs of the human body. They enter the body mainly with plant products and are the most important source of energy. Approximately half (56-58%) of the energy needed by the body is provided by carbohydrates. Carbohydrates are compounds made up of carbon, hydrogen and oxygen. Here, the relationship between hydrogen and oxygen is the same as in water molecules. That is why they are called carbohydrates. During physical labor, the need for carbohydrates increases. They are also involved in plastic forming processes. Carbohydrates increase the amount of glucose in the blood and increase the amount of glycogen in the liver and muscles, being included in the composition of cells and tissues. Glucose is converted into reserve carbohydrates - glycogen, which is an energy reserve that serves to maintain the level of sugar in the blood at a normal level and ensures the stable functioning of all organ systems.

The article presents the phytocenological and bioecological analyzes of Helichrysum aurantiacum Boiss. et Huet., an endemic species of the Asteraceae family and assessments in plant coenopopulations of the plant. The studies were carried out in 3 districts of Gazakh-Tovuz Economic Region of Azerbaijan. Ten natural populations where H. aurantiacum species are distributed were selected. In the selected populations, the integral characteristics of the demographic structure of the plant, age and efficiency indices were studied. The formations and associations were determined, the project cover of the areas was calculated, and the abundance was determined. In the H. aurantiacum species, the highest indicator is observed in the generative development stages (225-243 individuals were counted in the g1-g3 period). The efficiency coefficient of H. aurantiacum species in mature populations was ω=0.52-0.76. The high value of the efficiency coefficient in CP 7, 6 and 10 is related to the high number dynamics of plants belonging to the juvenile and immature phases before the generative development phases, and the small number of individuals belonging to the aging (s, ss) phases. The resource potential of the plant was determined and the biological reserve in the districts was 1241.1 centners, and the annual supply was 498.6 centners. This allows the supply of H. aurantiacum species in Tovuz, Agstafa and Gazakh districts located in the north-east of the Lesser Caucasus.

Phytophagous insects of malus in Uzbekistan
Статья обзорная
The paper presents descriptions of some of the most common apple pests. In Uzbekistan, the apple tree is one of the most important fruit trees. Damage to the apple tree must be controlled, and for this, all types of pests must be studied. Horticultural products from Uzbekistan are in demand on the world market. Currently, the export of food, fruit and vegetable products totaled about 5 billion dollars. Over the past three years, the volume of exported agricultural products has more than tripled. On fruit crops, one of the most dangerous pests are mites. Biological control measures on these crops have not yet been developed to the perfection as against pests belonging to the class of insects. There are studies where effects on the number of spider mites on an apple tree are noticed, where varieties with weak and medium pubescence are especially affected by the mite, and varieties with felt pubescence are slightly damaged.

The dendroflora of Ganja city includes the general composition of trees and shrubs naturally distributed in the city and used in greening. This flora has a significant impact on the ecological state of the city, its microclimate and the health of residents. The phytosanitary state of trees and shrubs used in greening reflects the health status of plants distributed in the area, their resistance to diseases, pests and environmental factors. From a phytosanitary point of view, exhaust gases and industrial waste cause a decrease in the quality of soil and air. This, in turn, creates stress in plants and reduces their resistance to diseases. In urban areas, tree species that are not suitable for the climate and soil are often damaged and stop developing. At this time, fungal, bacterial, viral diseases and pests develop, leading to the destruction of vegetation.

Pisum sustainability system to Na2SO4
Статья научная
Salinity is a major abiotic stress limiting growth and productivity of plants in many areas of the world due to increasing use of poor quality of water for irrigation and soil salinization. Plant adaptation or sustainability to salinity stress involves complex physiological traits, metabolic pathways, and molecular or gene networks. A comprehensive understanding on how plants respond to salinity stress at different levels and an integrated approach of combining molecular tools with physiological and biochemical techniques are imperative for the development of salt-stable varieties of plants in salt-affected areas. Recent research has identified various adaptive responses to salinity stress at molecular, cellular, metabolic, and physiological levels, although mechanisms underlying salinity tolerance are far from being completely understood. This paper provides a comprehensive review of major research advances on biochemical, physiological, and molecular mechanisms regulating plant adaptation and sustainability to salinity stress.

In this paper, the process of adsorption of organic compounds of the polyaminopolyphosphonates and polyaminopolyсarbonoates (chelators or complexones) class on iron (available in steel St3S (Poland) 97%) is modeled using the HyperChem package version 8.0.7 using the semi-empirical ZINDO / 1 method. The structures of chelators (“complexones”) for the study were chosen so that the sequential complication of the molecular structure could be traced. Such an approach, as will be shown below, accurately reflects the process of corrosion protection with bacterial content by chemisorption of an organic compound on the metal surface to form a complex compound. In the course of the study, the compositions of the complexes obtained, the energies of the boundary orbitals, and a graph depicting the dependence of the charge density on the iron atom on the component of the corrosion rate that is due to chemisorption effects were obtained and analyzed. On the graph there are equations of lines.
