Ortikov Nozimjon Boqijon ogli — 2022-09-12

In the article, analytical dependencies are obtained, which allow to determine the rational values of the parameters of the working organ (alignment angles to the horizon and sealing parts, the length of the working surface of the sealing part, the height of the working member and the vertical load on it), and the racists are shown to be obtained from them

Synthesis and Characterization of New nanoparticles compound

Bushra Farhood Zwaid — 2022-09-08

The development of competent green chemistry methods for synthesis of metal nanoparticles have become a main limelight of researchers in the field of nanotechnology.Nanoparticles are advanced matarials have recently gained high attention due to their scientific and technological important. They find awide variety of applications such as catalysts with huge activity and specificity,metal semiconductor In this thesis, preparation compound ( CuFe2O4@SiO2-PA-TFA MNPs ) synthesized CuFe2O4@SiO2 functionalized with propylamine and trifluoroacetic acid. Heterocycle compounds are an important compound of organic chemistry that exist in the structure of natural products and are responsible for the biological and pharmacological properties of most medicinal compounds. Characterization of CuFe2O4@SiO2-PA-TFA MNPs was performed by SEM, EDX, XRD, TGA and VSM analysis. Application of these nanoparticles in the synthesis of tetrahydropyrazolopyridines, shown high activity of the catalyst.

Review, Analyses of azo dyes' synthesis, characterization and biological activity

Aseel Fadhil Kareem — 2022-09-17

In this review essay, we discuss how dyes are used to color materials, particularly clothes. These dyes are colored by chromospheres, which are functional groups that absorb light. Azolo, nitro, and carbonyl groups are the most prevalent chromospheres. Another crucial component of dyes is auxochromes, which are functional groups that intensify color. Hydroxyl, amino, sulfate, and carboxylate groups are the most typical chromospheres. Nitrogen to nitrogen double bond serves as the chromosphere in azo dyes. Diazonium salt is combined with a highly active aromatic system to produce these colors.

Phase Transition in Pyrolyzed Samples of Natural Silk

B.Kh Islamov — 2022-09-17

The article discusses the use of non-recyclable fibrous waste of natural silk as electrically conductive materials for special purposes. The dependence of the electrical conductivity of powdered samples of natural silk on the heat treatment temperature is shown. A phase transition is described, in particular, the "metal-dielectric" transition in pyrolyzed samples of natural silk.

The Problem of the Existence of Itelligence

Yorqin Turopov — 2022-09-20

The article analyzes the issues of intellect and being, their interaction, the essence of man, his role in the perception of the essence of being, the factors and sources that determine the ontological structure and functional existence of an individual. The level of socio-economic development of society, the ideological and ideological environment, the essence of the policy pursued by the state, the content and form of the educational system determine the ontological structure and functional existence of the individual. Trends in the historical development of society are manifested in individual potential. The level of socio-economic development of society, the ideological and ideological environment, the essence of the policy pursued by the state, the content and form of the educational system determine the ontological structure and functional existence of the individual. Trends in the historical development of society are manifested in individual potential. The human mind is constantly developing on the basis of Learning, Mastering the various knowledge created by mankind. In order to further develop the mind, a person needs the right-thinking dormitory. To do this, Akli should rely on methods of cognition, in particular logical cognition. But it is of great importance that the quality of knowledge, advanced ideas and knowledge acquired by the individual in the bunda. Thus, the question of existence is the negation of all the issues that a person faced during his first attempts to understand the world wisely. The existence or nonexistence of certain things immediately took place from the centre of his attention, as soon as a person began to philosophical reasoning.

Method For Obtaining N-Permutite

F. I. Erkabaev — 2022-09-26

In production, various sorbents are used to soften industrial waters, including sodium permutite, which removes calcium and magnesium ions from industrial waters, replacing them in an equivalent amount with sodium ions. At the same time, the water softens, but its mineralization remains, only cations are replaced. Permutite-softened waters are used in steam boilers, if in this case hydrogen permutite is used, the salinity decreases and the operation of steam boilers, especially high-pressure steam boilers, sharply improves, and their efficiency also increases markedly. The purpose of this study is to obtain hydrogen permutite and study its sorption properties. It has been established that hydrogen permutite can be obtained from aluminum trichloride and sodium silicate in an aqueous medium, while the accuracy of the component ratio plays an important role for the formation of hydrogen permutite.

A spatial analysis of the drug phenomenon in Asia (2021)

Shakir Awad Dhahi — 2022-09-30

The aim of the research is to study the phenomenon of drugs in some of the countries of the Asian continent, the most prevalent drugs, according to the data of the International Drug and Crime Report for the year (2021), by knowing the most prevalent Asian countries for drugs, as well as knowing the most prevalent types of drugs on the continent, and the age groups most vulnerable to drug abuse, In addition to knowing the effects arranged on drug users on the continent, and put forward many proposals that may contribute to reducing the rise of the drug phenomenon on the continent, and with regard to the research methodology, it has been relied on the descriptive analytical method in studying many of the developments and variables that accompanied the geographical analysis of the drug phenomenon. In some countries of the continent, the data of the Drug Report (2021) was relied upon in order to give an accurate and clear picture of the spread of the drug phenomenon on the continent. The research revealed that the most drug-producing and consuming countries are Afghanistan, Pakistan, Laos, and Myanmar and that the continent of Asia is rife with opium and cannabis-type drugs. Amphetamine-type stimulants in Asia, and the research also showed that the most prevalent types of drugs in some countries of the Asian continent are opium and cannabis, especially during the period of the Covid-19 pandemic, and cocaine declined in varying proportions. This could be partly due to a shift in demand towards synthetic drugs in their places of existence, or it could be due to the increased effectiveness of global measures to address the drug phenomenon and its role in its decline.
