Power In Justice, Mustafo Muhammedovich Bayeshanov

Bulletin of Gulistan State University

The article analyzes the novel by M. Gorky "Mother and Temur" from the cycle "Tales of Italy". For Gorky, the real heroes were those who "create life in spite of death, who conquer death." A fairy tale in which the image of the mother is created, sometimes growing to the personification of the Motherland, acquires a deep philosophical meaning. Gorky begins the ninth tale with words full of deep meaning: “Let us glorify a woman - Mother, an inexhaustible source of all-conquering life! M.

Bulletin of Gulistan State University

Особое внимание проблемам словообразования в лингвистике уделяется еще со времен Махмуда Кошгарий. В целом в мировой лингвистике ведутся работы по таким проблемам словообразования, как выявление, классификация и описание способов их образования. Кроме того, в лингвистике тюркских языков особое внимание уделяется проблемам словообразования в тюркских языках. Кроме того, существует ряд научных исследований, направленных на раскрытие сущности словообразования в узбекском языкознании. В этой связи работы известного узбекского лингвиста А. Гуламова по словообразованию служат базовым исследованием этой проблемы, и А. Гуламов в своей работе ссылается на вклад работ А. Ходжиева в изучение способов словообразования в узбекском языке.

Bulletin of Gulistan State University

The article explains that by methods of ion implantation or bombardment it is possible to inject foreign impurities into the crystal lattice of metal substrates. For this purpose, a special experimental setup with a high vacuum condition is used. Under normal conditions, atoms or molecules of the atmosphere interact with the surface of solids. As a result of the diffusion process, atoms or molecules of the atmosphere penetrate into the near-surface region, into the crystal lattice of solids and form a connection of some type. Usually, this diffusion process occurs very slowly and for a long time, as a result, …

Bulletin of Gulistan State University

The article is devoted to the altitudinal and biotopic distribution of terrestrial mollusсs of the Zaamin mountains. Faunistic analysis showed that 31 species of mollusсs belonging to 19 genera and 14 families live in this region. The high-altitude distribution of mollusсs was carried out according to the classification of K.Z.Zakirov, where such high-altitude zones as chul (plains), adyr (foothills), tau (mountains) and yaylau (high mountains) were identified. Analysis by altitude belts showed that in the chul belt there are 4 (12.9%), in the adyr belt 20 (64.5%), in the tau belt 30 (96.8%) and in the yaylau belt 6 (19.4%) …

Discrete Model Of Heat Exchange Between The Tube And The Heat Carrier Passing Through It, Jurabek Saydullaevich Mamatov, Sardorbek Baxtiyor Ugli Dustnazarov

Bulletin of Gulistan State University

Convective heat transfer processes in heat exchangers, which are widely used in industry, are characterized by partial differential equations. Ensuring the adequacy of mathematical models leads to the complication of particular differential equations for products and boundary value problems for them. Acad. A. Azamov and candidate of mathematical sciences M.A. Bekimov proposed a perfect mathematical model of the heat transfer process in rotary regenerative air heaters (RRAH) at thermal power plants in the form of discrete dynamic systems, which made it possible to control the operation mode of RRAH, calculate smoke and air temperature. A mathematical model of the heat …

Bulletin of Gulistan State University

The properties of silicon carbide layers deposited to restore spent resources and unusable silicon heaters are investigated. The reasons for the low working life of heaters restored by applying only layers of silicon carbide are clarified. The possibility of restoring and increasing the working life of unusable silicon heaters by applying sandwich layers of silicon carbide and molybdenum disilicide is shown. An advantage of the proposed method is that the silicon carbide and molybdenum disilicide powders used to prepare the suspension can be obtained by grinding pieces (waste) of broken silicon carbide and disilicide molybdenum heaters.

Mechanical Composition Of The Mountain Brown Soil (On The Example Of Soils Of The Chatkal State Biosphere Reserve), Malika Alimovna Aliboeva, Zafarjon Abdukarimovich Jabbarov, Mashkura Fazliddinovna Faxrutdinova

Bulletin of Gulistan State University

In the article, mountain-brown soils differ from other soils in their development, genesis, evolution, chemical properties, especially mechanical composition, as well as many other properties and characteristics. These soils are considered as a key factor in their separation from soils, especially with their rockiness, humus content, carbonates, and rock distribution. The results obtained from the point of view of mechanical composition state that mountain brown soils are soils with medium and heavy mechanical composition. The specific gravity of these soils is 2.50–2.78g/cm3, and we see that this indicator is not high in the upper soil layers. In mountain brown soils, …
