One of the pathogenetic factors of bronchial metaplasia in smokers, susceptibility to poor-quality transforming diseases and measures to prevent early formation were examined by the authors. In smokers, a predisposition to bronchial metapilation is observed in 15% of patients, with long-term exposure to the airways, flat multilayered metaplasia of the columnar epithelium is observed. Accordingly, mitigation measures have been taken and early prevention investigated.
The article provides information on the effects of inoculation with nitragin and application of mineral
fertilizers on the microbiological properties of the soil before sowing the seeds of legumes (soybeans,
beans, mungbeans), grown as a secondary crop after winter wheat. At the end of the vegetation
period of repeated crops, it was observed that the amount of microorganisms in the soil increased
compared to the initial indicators, the amount of ammonifiers and oligonitrophils increased, and the
amount of micromycetes and actinomycetes decreased. Before sowing the seeds of legumes
(soybeans, mungbeans, beans) grown as a secondary crop, the amount of ammonifiers, oligonitrophils
and micromycetes increased, and the amount of actinomycetes increased compared to the control
option in the backgrounds treated with nitrogen-fixing bacteria.
In modern mechanical engineering, the development of a technological process for processing stamping forms on shaped surfaces remains the most important task of today. Before processing the shaped surfaces, it will be necessary to study the working surfaces of the stamping molds. This article describes methods for determining the geometric parameters of the surface when processing stamping forms on shaped surfaces, in particular, the drawing structures of the cutting zone of shaped surfaces, the penetration of the cutter into the cutting zone and data on the conditions of editing in the cutting zone.

Currently, robotics is widespread in almost all areas of activity and production. The need for the use of robotic equipment is due to the need to automate production and increase its volume due to this. The purpose of this article is to consider the significance of the use of robotics in the modern world. The global economic crisis, in which there was a need to increase labour productivity, caused an increased interest in the use of robots in industry. The research was initiated to find out how to best use robots, under what conditions they are cost-effective and how to design and manage the introduction of robotics

This article provides basic information on engineering selection and beautification of urban areas to be built in response to emergencies.
The article analyzes the state of development of the viticulture and wine industry in the Republic of Uzbekistan, analyzes the assortment and classification of products, highlights the requirement for the quality standard of table grapes (UNECE FFV-19), elaborates recommendations for ensuring the quality and safety of the wine industry and increasing their export potential.
In the spinning process, spinning machines have improved the stretching tool, reducing their
unevenness by straightening and parallelism of fiber ends, reducing the number of yarn breaks in the
production of quality textile and knitted fabrics, a sharp increase in labor productivity, reducing
production costs, other economic indicators.
The effect of various reagents on the quality parameters of cottonseed oil was investigated and the optimal reagents were selected. In the alkaline refining of cottonseed oil, the use of an aqueous solution of sodium silicate instead of a portion of the traditional caustic soda has been found to improve the quality of the oil. The technology of step-by-step refining of cottonseed oil with aqueous solutions of traditional caustic soda and sodium silicate has been developed.
Today, reducing the amount of trans acids in fats is one of the urgent issues, and several methods of its elimination have been developed. In this study, the technology of hydrogenation of vegetable oils in the state of supercritical fluid was studied through literature analysis. The principle scheme of the technology of hydrogenation of vegetable oils in the state of supercritical fluid has been developed and the norms of the technological regime have been determined.
Since glycerin is obtained from vegetable oils and fats, its quality directly depends on the quality of oil and fat. Also, the methods and technologies of obtaining and processing glycerine affect
the quality of glycerine. Based on the results of IK analysis, it was shown that the use of a mixture of
adsorbents to improve the quality of distilled glycerin is effective in the research work. If we look at the IR analysis results of purified glycerol, the IR spectrum of glycerol showed O-H stretching at 3338.15 cm -1 , and C-H stretching was detected in the peaks in the region of 2800-2950 cm -1 . The C=O stretching band present in unbleached glycerol at 1736.58 cm -1 is not present in the spectra of eluted glycerol. It was observed that the peaks observed in the spectra above 3600 cm -1 also disappeared. This means that the phenolic group of substances in refined glycerin has been purified.
Since margarine is a substitute for butter, milk is added in most margarine recipes. However, the cost of margarine obtained for the cost of cow's milk exceeds. The article presents the results of experiments on obtaining milk from soy beans and its use in place of cow's milk in margarine. When soy beans were taken and analyzed using soy milk in an traditional way, it was found that its ingredients were close to those of cow's milk. In particular, the protein content is 3.48% in soy milk and 2.31-2.84% in cow's milk. The carbohydrate content is 2.10% and 8.48 8.91%, the fat content is 1.96% and 0.11-0.14%, and the ash content is 0.28% and 0.21-0.26%, respectively. Cow's milk made a serious difference from soy milk in the amount of carbohydrates. On the basis of the resulting soy milk, a margarine recipe was formed and margarine was prepared. All the margarines obtained complied with the requirements of O’zDSt 3317-2018 in terms of quality indicators. It was observed that the consistency (plasticity, solubility, surface area on the cut) of margarines obtained only on the basis of the recipe with the addition of soy milk is relatively good.
Today, in our Republic, most of the baking oils are margarines prepared on the basis of food salami. These margarines do not meet the standards of trans acid content (more than 2%). The research paper presents the results of hydrogenation of cotton palmitin in the presence of a regenerated catalyst, the melting temperature of which is less than 59 °C and the iodine number of no more than 6, and the preparation of a recipe for margarine with reduced trans acid content, which is used in baking based on it.
Coconut oil should be used in chocolate and chocolate products. However, due to the high cost of coconut oil, its substitutes have been developed. The article contains information about cocoa used in chocolate products and oils used instead. Also, the results obtained as a result of the analysis of the physical-chemical parameters of confectionery oils and coconut oil substitutes used in chocolate products are presented. As a result of the research, it was found that the amount of trans fatty acids in the analyzed oils is higher than the standard norms.
