Almalyk branch of National University of Science and Technology “MISiS”
Currently, a variety of mathematical modeling methods are widely used in various applications describing chemical processes. Some stochastic models of chemical reactions rely on the theory of Markov processes. Due to the peculiarities of certain chemical reactions, it is the Markov property that makes it possible to form a mathematical model that most fully describes this process. The traditional approach to the analysis of Markov models is the compilation and solution of Kolmogorov differential equations. In this paper, the Markov model of monomolecular reactions is introduced, using the example of iron allotropy. The analysis of the model includes solving the system of Kolmogorov’s differential equations. Restoration of the desired functional dependencies is carried out using Laplace transforms. The data obtained as a result of modeling are interconnected by an exponential dependence. A change in the mass of iron modifications at a random time is predicted. | | |

Measurements of electrical conductivity induced by a pulse of high-energy electron braking radiation and a pulse of light in the spectral range from 360 to 900 nm in a solution of N2O in liquid isooctane were carried out. In this spectral region, photoconductivity was detected at a light intensity less than 1021 photons cm2 sec-1. The magnitude of the photocurrent Iph decreased with an increase in the delay time td between the electron pulse and the light pulse with a characteristic time Tph ?7•10-4 sec at T=296K, weakly dependent on the concentration of N?O when it changes from 1014 to 1015 cm-3. It is assumed that the occurrence of a photocurrent is associated with the photo separation of an electron from the N?O- ion, and the decrease in Iph with an increase in td is mainly determined by the stability of this ion. Based on the temperature dependence of Тph, the dissociation energy of the N?O – ion in isooctane is estimated to be 0.5 ± 0.1 ev. The dependence of Тph on the concentration of nitrous oxide is associated with the reaction N?O- + N?O, which leads to the death of ions with a rate constant of 1 ? 10-12 cm3 sec-1. By studying the electrical conductivity induced by an electron pulse, the rate constant of the electron capture reaction by a nitrous oxide molecule was determined equal to (1.5 ± 0.4) ? 10-8 cm3 sec-1. | | |

The results of geoecological engineering studies of salinization of soils of the Nukus district of the Republic of Karakalpakstan to the groundwater level are presented. The results of observations of changes in the groundwater level of the district are presented. It has been established that an increase in the level of groundwater leads to additional salinization of soils, which worsens the ecological situation of the areas. According to the results of research using GIS technologies, maps-schemes of salinization of soils of the district were compiled. Studies have shown that the soils of the territory of the Nukus district are saline and mainly belong to the sulfate and chloride-sulfate types of salinization. According to the degree of salinity, soils belong to the saline type. It is established that the most saline soils are located between the channels Doslyk and Tas Arna and on the left bank of the channel Tas Arna. It has been established that the territory of the village Akmangit belongs to the chloride type of salinization. The area around the village of Akmangit is salted with sulfate-chloride salts. Recommendations are given for reliable design and reconstruction of buildings and structures on saline soils of the Nukus district. It is proposed to build a new innovative drainage system to reduce the negative impact of salts on buildings and structures. | | |

This article analyzes the increase in noise on highways, the causes of noise. The harmful effects of noise on roads and the environment have been studied. The factors influencing the occurrence of traffic noise and its increase were studied using the example of Sharof Rashidov Avenue in Jizzakh. Sources of vehicle noise and factors affecting it have been measured in accordance with international regulations. Based on the results, the influence of indicators of speed, intensity and noise of vehicle traffic on the investigated main street was determined and analyzed. The graph of the influence of the speed of movement on the noise on the roads has been drawn up, the main indicators of which are determined in real road conditions. With the increase in traffic, there was a parallel increase in road noise. Noise levels have been found to increase due to the presence of trucks on city streets and old-fashioned cars produced in the last century. The maximum noise level was determined at points with a high noise level on the track and its causes were investigated. Also, the most effective methods of organizing road noise protection were identified and analyzed. Based on this, this article has developed effective methods for organizing noise protection on city streets and highways and presented the main solutions to the problems.

The construction of a combined dam with a through part of tetrahedrons has been developed. This kind of construction eliminates the main disadvantages of waterproofing and permeable dams, namely the depth of local washing and the bypass flow from the point where the dam meets the shorelines. Experimental and theoretical research has been conducted. Physical processes were established. The solution for the case where the ratio of the length of the permeable part of the dam to the length of the entire dam is less than 0.5 was given in our previous article. In this article, the solution is given for a case where this ratio is greater than 0.5. The experiments revealed the formation of satellite flow in the water-permeable part of the dam, the formation of a low-impact core and two turbulent interference zones, in which the velocity propagation is universal and obeys the theoretical laws of Shlikhting-Abramovich. The article solves the problem for a "quiet" mode. In this case, the problem is solved by applying the integral expression describing the law of conservation of momentum in the flow, the equation of conservation of flow and the differential equation of uneven motion written for the satellite flow behind the permeable part of the dam. Expressions are proposed to calculate the velocity in the compression shaft, the average velocity and depth in the satellite flow, and the velocities in the core and satellite flow. In contrast to the existing solutions, the presence of satellite flow, two turbulent interference zones, main and satellite currents with different water level slope is taken into account. The comparison of theoretical solutions with experimental studies gave satisfactory results.

The article shows that to obtain polymer materials with improved properties, the modification of large-scale industrial polymers with small additives of other polymers or oligomers is widely used. The introduction of small amounts of finely dispersed crystallization nuclei, thermoplastic elastomers, oligomeric and polymer additives has become widespread. Modification of polymers or oligomers with small additives was based on the concept of a significant effect of the supramolecular structure, as well as the conditions of relaxation processes on the properties of polymers. At the same time, there is a complex effect of additives on the structure and properties of polymers. A large number of studies are devoted to the chemical modification of epoxy polymers and it has been shown that their modification is most effective even at the stage of mixing the components, when modifiers are introduced mainly with hardeners during the formation of polymerization centers, the growth of the polymer chain, and the formation of a polymer network. The use of polymer modifiers is promising from the point of view of preventing some undesirable processes inherent in low molecular weight modifiers, as well as their use in small quantities.

The paper presents data from a study of the heat treatment of serpentinite from the Karakalpakstan deposit. According to the derivatogram data, it was found that the first endothermic effect, associated with the removal of adsorbed water, was obtained at a temperature of 170°C, the second, associated with the destruction of the structure at 680°C (mass loss in this region is 10%). Heat treatment of serpentinite is an important step in the technology of its processing. When choosing the optimal parameters for the heat treatment of serpentinite, it is necessary to conduct thermoanalytical studies to study the dehydration of serpentinite, which is the main chemical stage of firing. Based on this, in this work, we studied the phase composition of the intermediate and final products of heating the serpentinite of the Karakalpakstan deposit.

The process of preparing complex glauconite-containing fertilizers based on glauconite, Karakalpakstan and fertilizing salts was investigated. Glauconite-containing fertilizers based on glauconite, nitrogen and potassium fertilizers can be obtained, their K2O content ranges from 21,9-54,5 and 0,5-3,9%, respectively, when potassium chloride and nitrogen fertilizers are added. The results show that the more additive (potassium chloride, ammonium nitrate, ammonium sulfate, carbamide) is added to the glauconite composition, the higher the strength of the product granules is obtained. Also shown are diffractograms of binary mixtures of glauconite sands with ammonium nitrate, ammonium sulfate, potassium chloride and carbamide. It has been determined that in complex fertilizers the introduced components may be crystalline or amorphous due to interaction with water, glauconite and other sand components.

The value of artemia used as food for fish, crabs and shrimps grown in artificial conditions of aqua and mariculture depends on its chemical composition. It is also known that lipids, which are used as plastic and energy material in cultured organisms, are of particular importance in assessing the feed value of the crustacean. Artemia cysts contain a significant amount of lipids, but their qualitative composition is not the same. The article presents the results of comparative studies of the biochemical composition of crustacean biomass and artemia cysts of the Aral Sea with artemia populations from 6 salt lakes of the Pavlodar region of Kazakhstan. It was found that the studied objects from the Aral Sea are characterized by a high content of protein (81.6-49.2%), free amino acids (285.93-335.49 mg). There were seasonal fluctuations in the content of dry matter, free amino acids, total lipids, total carbohydrates in the crustaceans of the studied populations.

This article provides an overview of the state of development of the hydrocracking process and secondary processes, as well as the role of hydrocracking and the prospects for its development. The range of modern hydrocracking catalysts is quite extensive, which is explained by the variety of process purposes. They usually consist of the following three components: an acid, a dehydro-hydrogenating agent, and a binder that provides mechanical strength and a porous structure. Increasing demand for motor fuels with a lower sulfur content and less emissions of pollutants into the atmosphere during their production and combustion influenced the birth of such a process as the catalytic process of hydrocracking of raw materials under hydrogen pressure. The main purpose of the hydrocracking process is the production of hydrotreated gasoline fractions, commercial kerosenes and diesel fuels, as well as liquefied gases from heavier oil feedstock than the resulting target products. In addition, if the non-reacting residue is not returned to the hydrocracking feedstock, then it can be used as a high-quality feedstock or component of catalytic cracking, coking, pyrolysis feedstock. The hydrocracking process has been successfully used to produce high index lubricating base oils. Hydrocracking combines catalyticcracking and hydrogenation.

This paper presents the results of many years of scientific research conducted in the lower reaches of the Amudarya River. The main material was our own collection of ichthyological material - carp species of fish to determine its current fishing status. As a result of the research, the state of protected cyprinid fish species was revealed in connection with the anthropogenic transformation of the hydrological regime of the Amudarya River. Changes in habitat conditions have led to a violation of the migration regime and the reproduction of species, changes in their population structure and life cycle, which has led many species of aboriginal ichthyofauna to a critical reduction in numbers and to the verge of extinction. In the current composition of cyprinids of the lower reaches of the Amudarya, taking into account their status and place in the ecosystem of the region, we have identified a complex of protected cyprinids with official conservation status. These include the following 5 species: Luciobarbus brachycephalus, Kessler, 1872; Luciobarbus capitoconocephalus, Kessler, 1872; Ballerussapa (Pallas, 1814); Capoeto brama kuschakewitschi (Kessler, 1872) and the Leucis cusidusoxianus (Kessler, 1877).

Since the 2000s artemia (Artemia parthenogenetica) has become a permanent and dominant component of the Aral Sea plankton. Diameter of brine shrimp untreated cysts of the Aral Sea population collected in the southwestern part of the water body was investigated. Cysts were collected in November 2020 in the southwestern part of the remnant of the Aral Sea (Uzbekistan). Purification of Artemia cysts harvested in the water or on the shore and containing various impurities (which accounted for up to 60% of the collection mass) was carried out by conventional methods. A small number of cysts (about 1000) were incubated in half a Petri dish at room temperature (26-28°C). Salt water (salinity 70o/oo) was used as the incubation medium. A few drops of Lugol's solution were added to the cup. Cyst diameter was determined on fully hydrated cysts. The minimum values of cysts in diameter were 200 microns, the maximum ones - 360 microns, the average - 280 + 3.00 microns. The coefficient of variation was 10.6%.

The article discusses the use of innovative technologies to assess and monitor the resource potential of Karakalpakstan vegetation. The basic principles of the technology of monitoring and quantifying ecosystem services of plant cover, combining methods of mathematical modeling, direct field observations, remote sensing and contact measuring methods. The identification and quantitative assessment of climate-forming characteristics of natural vegetation is proposed, and landscapes are made on the basis of data collected during expeditionary work using contact and remote methods. It is noted that such a Karakalpakstan function of vegetation, like a soil melting, a decrease in the wind removal of salts from the dried bottom of the Aral Sea, the weakening of the migration of the sands, the regulation of climate warming is estimated for the first time. These useful functions of plant cover refer to the category of non-valuable indicators of ecosystem services. In addition, such services are characterized only for the Southern Priaral, therefore, in the global practice of evaluating environmental services, there are no similar techniques. The development of innovative remote sensing technology will significantly expand the review of the territories of engaged in vegetation with sufficient detail, increase the frequency of observations by several orders of magnitude. At the same time, this technology of satellite imagery processing includes recognition of the structure of plant cover by plant species, which will allow to monitoring the dynamics of sakes occurring.

Karakalpak Research Institute of Natural Sciences of the Karakalpak Branch of the Academy of Sciences of the Republic of Uzbekistan, Nukus
The Republic of Karakalpakstan, located in the north of Uzbekistan, which is affected by the arid climate of the Aral Sea region, formed as a result of the drying of the Aral Sea, is a striking example of the importance that vegetation has for its improvement. The expedient planting of vegetation could have such salutary effects, precisely here. Therefore, it is necessary to develop measures for the scientifically based implementation of landscaping and to select such a range of trees and shrubs that would best responds to the improvement of the quality of the living environment. For this, it is necessary to develop a long-term concept for the development of green building in Karakalpakstan. This concept should be based on a set of science-based measures to modernize landscaping through the introduction of an updated range of woody plants, taking into account soil and environmental conditions, developed recommendations and technologies that allow growing a variety of biologically stable and durable plantings in a wide landscape and architectural range. We have proposed the following scheme of the concept: 1. analysis of modern landscaping; 2. accounting for soil and environmental conditions in the areas of new landscaping; 3. substantiation of the composition of plantings by categories of landscaping objects; 4. development of technology for growing promising plantations using introduced plants; 5. expansion of the network of nurseries for growing seedlings of wild and ornamental plants. Thus, this concept will allow creating a long-term program to improve the habitat, which in turn will reduce negative climatic factors, as well as the developed methodological recommendations will allow growing new sustainable ornamental plantings, and contribute to the reconstruction and improvement of existing plantings.

The article presents the phytocenoticcharacteristics of the Halocnemum strobilaceum pasture variety (PV), which is part of the Halocnemum strobilaceum pasture type. The described type of pasture is widespread in the central part of the Karakalpak Ustyurt. Halocnemum strobilaceum pasture variety (PV), on wet salt marshes in combination with blinders devoid of vegetation is located in the Kungrad district, geographical points: Shore Barsakelmes, Sarykamysh basin, the area of the pasturevariety (PV)is 31495 ha. The total projective cover of the PV is 20%. In the composition of this pasture variety, only 4 species were noted: Halocnemum strobilaceum (Pall.) M. Bieb., Tamarix hispida, Kalidium caspicum (L.) Ung.-Sternb. and Limonium suffruticosum (L.) Kuntze. All species except Halocnemum strobilaceum as assemblers of this plant community are found isolated and their role in the addition of the projective cover of the herbage is small. The varieties are characterized by sparsity of vegetation cover and extreme poverty of species composition, reaching in some cases to a monodominant community. According to the results of the study, we see that due to the arid climate, the eaten part of the forage mass of the Halocnemum strobilaceum pasture variety is low and ranges from 0.9 to 3.6 c/ha. According to the yield indicators, the Halocnemum strobilaceum pasture variety can be recommended for use as autumn-winter pastures.

This article provides for the milk productivity of single-humped camels depending on the shape of the udder, constitutions, and pasture conditions. Dairy productivity was studied on saxaul pastures, semi-desert ephemeral pastures in the main desert territories of Karauzyak district and on amber pastures that are closer to rural settlements. According to the data obtained, according to these indicators, the total milk yield in the first group of saxaul pastures was 3186 grams, while in the second and third groups there were 5007 and 4880 grams, respectively. The highest milk yield was obtained on amber pastures than on semi-shrub ephemeral pastures (1821 grams), and 127 grams more than on saxaul pastures. Camels with a cup-shaped udder have a much higher milk yield compared to their peers with rounded udders. Milk yield has also been studied depending on the constitution of animals that are more milk productivity of coarse constitutions. The chemical composition of the milk of camels of different ages has been analyzed, which fluctuations in milk fat in the age range fluctuate from 0,1% in the period from 5 to 9 years. The chemical composition of milk is primarily directly related to storage, feeding and the time of year. It should be noted that camels that received additional feeding have high protein, fat and sugar content in milk.

Bobokulov N.A., Urimbetov A.A.
Research Institute of Karakul Breeding and Desert Ecology, Samarkand
The article presents the results of increasing the productivity of young karakul sheep with the rational use of concentrates. The concentrates are enriched with nitrogen-containing substances. The harsh conditions of Karakalpakstan, which are distinguished by a sharply continental, arid climate - hot summers, cold winters, seasonal and uneven precipitation, have developed parameters in the Karakul sheep breed that are superior to other breeds. Reducing the proportion of concentrates in the diet by 15-20% due to the treatment of straw with urea does not reduce the productivity of sheep. For the experiment, rams and ewes were selected. And formed two groups, control and experimental groups. The reduction of concentrates in the diet by 10-15% in the experimental groups made it possible to maintain the slaughter qualities of rams in comparison with the control, due to the feeding of ammoniated straw. The use in the practice of farms of the recommendations of scientists to improve the quality of feed, by enriching with nitrogen-containing substances, reduces the cost of concentrates, reduces the cost of production. The results contribute to reducing the cost of production in stall fattening. The profitability of fattening with the use of ammoniated straw is 22.2-15.7% higher than in the control without the use of urea treatment.

The changes of hydrogeological situation create the special anthropogenic dynamic quality of natural environment and health of population often. It is set that the ecological terms of region of Southern Priaralye cause tension of adjusting and function of erythrogenesis, and similarly conduce to unfavorable possibilities of functioning of both hematogenesis vehicle and erythron. Change of indexes of the system an erythron for the inspected children in the ecological terms of region of South Priaralye carries unidirectional character without depending on the type of diseases. The children inspected by us have changes of the system erythron, that, mainly, does not depend on the type of disease and determined by the direct presence of pathological process. The changes of middle volume of red corpuscles and middle concentration of hemoglobin are most expressed in red corpuscles. The fact marked by us testifies in behalf on that at any disease of breathing organs the scray mechanisms sent to the increase of providing with of fabrics oxygen are included. Quality and ecologically safe drinkable water-supplys must be pulled out on a priority plan in development of the system of the events sent to the improvement of terms of life and state of health of population of Republic of Karakalpakstan.

Nukus branch of Uzbekistan State Institute of Arts and Culture
Studying the state of the public education system of Karakalpakstan in the 1980-s is a very important research task, because during this period the first attempts were made to reform the entire system of education, culture and art, flaws and omissions were indicated, which predetermined the understanding of the need to develop national culture and restore the spiritual and moral heritage of our people. In the early 1980s the Soviet state takes a number of measures aimed at preventing deep crisis phenomena in the entire system of economic, social and cultural relations. The "Main Directions for Reforming the General Education and Professional School," the so-called "school reform," were adopted. These decisions were an attempt to "resuscitate" the system, which was in deep crisis. During these years, the level of work aimed at attracting the population to cultural centers and creating the necessary conditions for them. The attitude towards cultural construction as to cost-effective, non-profitable area is being reduced material support of culture. By 1991, 689 schools functioned in the republic, while only 40% of the schools were typical (educational building, corresponding material and technical base, sports hall, etc.), and the rest functioned in adapted buildings. The quality of training, preparation, specialization of shots, providing with material and technical resources was not ideal.

Karakalpak Research Institute of Humanitarian Sciences of the Karakalpak Branch of the Academy of Sciences of the Republic of Uzbekistan, Nukus
In the 1930s, a network of republican and regional newspapers was formed in Karakalpakstan, which were considered as the main means of agitation and propaganda by the ideologues of the Soviet government. The article analyzes the state of the press during the Second World War and the issues of strengthening party control over the press. A sharp reduction in the financing of newspapers is indicated, as a result of which some republican and district publications were closed, the volume and circulation of other newspapers and magazines decreased. The periodical press of Karakalpakstan also suffered personnel losses, since most of the journalists and intellectuals who collaborated with it went to the front. Party control over the press was carried out through censorship and the compilation of a review of newspapers published by the agitation and propaganda department of the local party committee. The study of the periodical press of Karakalpakstan during the war allows us to characterize the ways of involving the population in the propaganda process, to reveal the essence and mechanisms of mutual influence of the periodical press, propaganda and the audience.

Depiction of images of historical figures in Karakalpak folk legends
Бекимбетов А.М.
Karakalpak Research Institute for the Humanities of the Karakalpak Branch of the Academy of Sciences of the Republic of Uzbekistan, Nukus
In legends about historical figures, instead of heroes in improved plots based on various beliefs of the ancient mythological period, a historical figure is taken that is known in the history of mankind or at the level of a certain territory, and the ancient mythological plot is transformed in accordance with the new period. And in legends about a historical period or historical events, on the contrary, one specific historical period, social formation or event is depicted around the images of mythological heroes. The author notes that in the Karakalpak folk legends, the most common group of legends brought into a certain cycle is about a historical figure known as Iskandar Zulkarnayn (Alexander the Great) in the oral folk art of the East and in the article he cites the arguments of E.E.Bertels, E.A.Kostyukhin about the image of Alexander the Great. The most common legends among the Karakalpaks about King Sulaiman are the legends that arose on the basis of the motif of the magic ring, given in the sources of oral folk art of the East: “The Magic Ring of Sulaiman”, “King Sulaiman and the Servant”. And both legends begin with the image of the majesty and wealth of King Sulaiman, his power over all creatures. According to legend, the power of Sulaiman over the whole world is associated with his magic ring. In the legends about Sulaiman, in the system of Karakalpak folklore, he is known mainly as the ruler of the whole world, that is, as a ruler.

Karakalpak Research Institute for the Humanities of the Karakalpak Branch of the Academy of Sciences of the Republic of Uzbekistan, Nukus
The Karakalpak folk epic is very complex in composition. The epics are extensive, and the content of this genre retains the views of several periods. Epics have the beginning, formation, development and completion of plots. Among them, introductory plots (prologue) are of great importance. The reason is that these plots are the beginning of the events taking place in the epic. All episodes develop through the prologue. The plot of the event, conflict, climax, decisions will be connected with the prologue. All folk epics, epics begin with the birth of a hero. A newborn baby is not an ordinary person, but a hero. He was born a hero who in the future will serve the interests of his people and defend his homeland from enemies. However, his birth is through prophetic powers. The reason is that the hero who brings the dreams of the people to life should not be ordinary. They are born with the help of divine forces. Heroes defeat thousands of enemies with the help of divine powers. Such prophetic tribal movements are enriched with mythical elements. At the beginning of the saga (dastan, epic) fathers become childless. With the help of extraordinary people, fathers will have children in old age. The article examines the images of childless fathers depicted in the Karakalpak folk epics. The author analyzed these images on the basis of scientific and practical materials and sources.

Literary role of gradation in karakalpak poetry
Otarova T.J.
Karakalpak Research Institute of Humanities Science Karakalpak Branch Academy Science of the Academy Science of Uzbekistan, Nukus
The article examines one of the most important issues of Karakalpak literature: the peculiarities of using gradations in a literary text, including poetry, on the examples of talented Karakalpak poets Askerbay Adzhiniyazov’s and Tenelbay Sarsenbayev’s lyric songs. Gradation has an artistic and poetic quality and stands next to tropes as a metaphor, metonymy, comparison, epithet, etc. However, the difference between gradation and other types of tropes is that in the literature “gradation”, depending on its function, is a gradual rise: “degree” means “step”, “level”, 1) sequential and slow distribution of steps in the process, 2) a stylistic element, consisting of a series of strengthening or weakening of a number of words in terms of meaning and emotional characteristics. The role and significance of the phenomenon of gradation in the poetry of Askerbay Adzhiniyazov and Tenelbay Sarsenbayev were analyzed on the basis of a number of scientific and theoretical works. We analyzed the usage of types of gradation such as climax and anti-climax in the poems of the above-mentioned poets, who wrote poems on various topics such as birth, Motherland, mother, love, etc., as well as the feelings of the lyric hero. Based on the analyzes and the results obtained, a corresponding conclusion was made.

The need for the scientific study of language in interaction with culture has become a prerequisite for the emergence of a number of new disciplines that develop at the intersection of different areas of humanitarian knowledge - linguistics, mythology, folklore, sociology, philosophy and ethnography. So, at present, the folklore text is the object of description not only of folkloristics and textual criticism, but also of new disciplines related to them - ethnolinguistics, linguo-folkloristics, linguoculturology. As a new discipline in linguistics, linguistic schools have formed that comprehensively study the subject, object and methods of ethnolinguistics, as well as the traditional culture of the people on the basis of language, folklore, beliefs, rituals. At present, three centers of linguo-folkloristic research have been formed in Russian science - Voronezh, Petrozavodsk and Kursk. The article for the first time provides information about ethnolinguistic analysis in folklore texts in linguistics.
