In the study, the catalytic hydration reaction of acetylene in the presence of catalysts based on local raw materials was carried out under stationary conditions in a flow reactor made of stainless steel with a diameter of 25 mm and a height of 1000 mm. The reaction products were analyzed chromatographically. In the presence of the created fluoride catalyst, the conversion of acetylene is 75-80%, the yield of acetaldehyde is 93%, the yield of acetone is 2.5%. The reason for the high activity of cadmium-zinc-aluminum catalysts is explained by the fact that they form the active center of ox fluorides on the surface of the catalyst. The effect of temperature, volumetric velocity, acetylene: water ratio, etc. on acetaldehyde yield in the presence of the selected catalyst was studied. When the effect of temperature was studied in the range of 300–440oC, an increase in acetylene conversion and a decrease in acetaldehyde selectivity were found with increasing temperature. X-ray studies have established that cadmium-chromo-fluoro-aluminum catalysts have high activity in polymorphic-crystalline state.

Phytoremediation is a promising elective technique to treat modern effluents, predominantly in light
of its minimal effort and high metal restricting limit. In this work, Zinc and Chromium Phytoremediation
process by Sargassum sp. ocean growth biomass was examined . The work considered the assurance
boundaries of Zinc and Chromium sorption for example, pH, temperature, unsettling rate and biomass
size. The ideal conditions were: pH3, temperature (303k) room temperature, biomass size 0.5mm and
fomentation speed 150rpm. The greatest take-up of Chromium and Zinc is 65% and 53% separately. The
motor examination uncovered that the adsorption of Chromium and zinc by Sargassum sp . fitted the
Langmuir isotherm.

At the same time, the article assesses their impact on the socio-political stability of society based on the analysis of the concepts of cyberterrorism, cyber-attack and cybercrime manifested in the virtual space.

The article highlights the objective necessity of increasing the competitiveness of the national economy and the importance of using innovations in this process. It is emphasized that innovation is a key criterion for building a competitive economy in the context of declining traditional and limited non-renewable economic recources. Priorities for increasing the competitiveness of the national economy through the innovative development of industries are outlined.

Mirzachul regions were part of the historical region of Ustrushna in ancient times. The article notes that Ustrushana is not only a country suitable for animal husbandry, but also a developed agricultural culture in its fertile plains, which are connected with the steppes. The urban culture of the ancient and medieval Ustrushona is illustrated by such monuments as Eski Havas, Ordatepa, Qaliyatepa, Oydinsoytepa, Qurghontepa. It is noted that the Sangzor and Zamin rivers and a number of small rivers played an important role in the development of these settlements. The article reflects the historical, historical structure, objective historical analysis of artifacts.

This article is dedicated to the 16th century scholar Fakhruddin Ali Safi ibn Husayn Waz Kashifi Hirawi (1463–1533), a mature manaqibnavis and tazkiranavis who lived and left a rich scientific legacy. Fakhruddin Ali Safi ibn Husayn Waz Kashifi Hirawi's (1463–1533) work “Rashakhot aynu-l-hayat” (Drops of the spring of life) dedicated to Hodja Ubaydullah Ahror and in this work The description of the Eleven Blessed Phrases, which is explained in detail under the name, in particular, is devoted to the study and interpretation of the phrase “Hush dar dam” (remembering Allah at all times, engaging in the remembrance of Allah), the first foundation of the first Khojagan sect.

The World Gold Council and its member companies support the responsible mining and trading of gold from all legitimate sources, including artisanal and small-scale mining (ASM).  The responsible development of gold resources both through large-scale mining (LSM) and ASM, especially when coupled with sound governance, has the potential to deliver broad social and economic benefits to individuals, communities and countries.  There has been a significant growth in artisanal and small-scale mining in many developing countries over the last twenty years. ASM issues have become more salient in public policy debates as a result of the adoption of instruments designed to prevent the funding of illegal armed groups and from the implementation on reducing mercury in the environment. Artisanal and small-scale mining is more than simply an industry with the potential to contribute positively to foreign exchange earnings and employment; it is a way of life. Its participants, most of whom were lured into work by the prospect of gaining wealth quickly, include rural community dwellers, nomadic peoples, seasonal subsistence farmers, and retrenched large-scale mine workers. However, despite providing higher wages than comparative rural sectors of industry, artisanal and small-scale mining is generally associated with a deteriorated quality-of life

This article is devoted to the review of  the researches  carried out in the direction of Boburology by local and foreign boburologists.

This article illuminates the scientific views of procedural sciences, the legal nature of other fees connected with criminal proceedings that is generally recognized in criminal procedural legislation on the basis of the analysis of current legislation norms as well as the types of expenditures that is probable to include in it are distinguished. Moreover, the need to reflect in legislation as a new type of procedural fees the costs incurred to cover the damaged or destroyed items during the experiment, search and other investigative actions, as well as the expenses to ensure the protection of some participants in the criminal proceedings are grounded.

Starch consists of two types of molecules namely, amylosse and amylopectin .Amylose, a linear chain polymer constitutes about 20% of starch. It is more soluble in water, soluble in hot water but does not form gel while amylopectin is a branched chain polymer that constitutes about 80% of the starch. It is less soluble in water, soluble in hot but forms gel, hence the need for modification. In this study, Cassava starch was modified with distilled water, glycerol and vinegar. The cassava starch, distilled water, vinegar and glycerol were all weighed in required proportions into the beaker. 50g of cassava starch was weighed into a beaker, 10mls of vinegar was added. 20mls of glycerol was also added. The resulting mixture was thoroughly stirred to form a uniform suspension, the suspension was heated, and it was continuously stirred to avoid coagulation with increasing viscosity until gelatinization was achieved at about 100°C. The gel was spread on a smooth, hard surface and mechanically pressed to form sheets. The sheets were air dried to cure for 72hrs to 5% moisture content. The sheet was subjected to tensile test. Water was used as a solvent to first get the biopolymer (starch) into solution. When the solution was heated, the water helped the starch molecules to become disrupted and disordered (denatured). The reduction of starch hydrogen bonding was achieved in the presence of water. Water diffused into the starch granules and hydrogen bonds breaking down the intermolecular bonds of the starch molecules. Water helped the starch molecules to become disrupted and disordered.  When the starch was heated with water, water interacted with hydroxyl
