It is shown that the main factors providing the processes of drying agricultural raw materials are thermophysical properties and dimensions, the shape and condition of the outer surface, the interval of changes in the moisture content of the material during the drying process, etc. The internal structure of the material has the strongest effect on the drying process. For dispersed materials with particles with a diameter of more than 2 mm and a critical pore radius of less than 2 nm, the duration of convective drying is more than 1 h, while for dispersed materials with a critical pore radius of more than 100 nm (all other things being equal) it is within 0.5 - 3 p.

Research is being conducted in Uzbekistan on the cases of symmetrical operation of low-voltage (0.4 kV) power distribution networks. One of the main reasons for the excess of electricity quality indicators over normative indicators is the uneven distribution of network phases, which leads to an increase in energy losses.

In the research work, it was proved that the silk yield depends on the hybrid, weight, hardness, size and thickness of the cocoon shell of the silkworm.

At the same time, it has been studied that the initial processing modes of the cocoon, storage, sorting, evaporation of the cocoons and spinning of the cocoons have a great impact on the output of raw silk. The thickest part of the cocoons is the waist, which varies from 0,14 mm to 0,45 mm. These figures also indicate the anisotropy of the cocoon shell. In order to reduce the anisotropy of the cocoons, we found a noionogenic SАM to obtain the solution and process the cocoons. We prepared different concentrations from the obtained SАM and studied their absorption into the cocoon shell. As a result, in the study, it was found that the cocoons were treated with a 0,1% SAM solution to determine the wetting and permeability properties, which improved the yield of raw silk. As a result of cocoon processing, the output of raw silk increased by 4.36% compared to control, the output of silk increased by 3,37%, and the output of cocoon skin decreased by 2,27%. The specific consumption of cocoons was 2,76 kg.

This paper talks about consistent state investigation and execution qualities of a three-stage
enlistment generator self energize with capacitor per stage. It is indicated that for this method of
activity, there are sure ranges over which the estimations of the terminal capacitor, C, machine speed

self energized enlistment generator under fluctuating rotor speed activity of examination. Three stage
3.7kW enlistment machine energized with even capacitor bank and stacked with balanced three stage
resistive burden, was the subject of examination. Tentatively acquired outcomes have been
contrasted and determined execution bends and awesome understanding between them has been
accomplished.

This article analyzes the indicators in determining the quality of cotton fiber in the production of cotton yarn. For the analysis and research, we used the characteristics of the fiber of the selection cotton varieties, which differ sharply in terms of indicators. The system calibration procedure is used to determine the fiber quality. Differences in fiber performance in equipment have been found to affect the quality of yarn in spinning mills. An analysis of the theory of factors influencing tissue virility is presented. It is shown that the differential equations of the yarn, in which the law of deformation of linear and nonholonomic bonds remains linear, are nonlinear.

The study investigated the possibility of using catalysts based on compounds of cadmium, zinc and other elements filled with orbital electrons d10, having several polyfunctional properties, as well as promoted by compounds of various metals in the hydration reaction of acetylene and its derivatives. The acetylene hydration reaction yields acetaldehyde or acetone depending on the composition and nature of the catalyst used under the same conditions. In particular, the formation of acetylene at 360-440 0C in the presence of a catalyst from cadmium fluoride-containing 20% CdF2, 5.0% AlF3, 75% Al2O3: acetaldehyde formation when reacted with water = 1: 3-1: 5, cadmium fluoride, It has been found that using catalysts containing zinc, iron, nickel, cobalt compounds instead of aluminium fluoride, the process leads to the formation of acetone.

Heavy metal is used to refer to metals and semi-metals with a density of more than 5 gr/cm3. The rapid developments of the new technologies in numerous projects and soil contamination by heavy metals, make the soil structure poisonous for plant growth and development, and they all damage the soil biodiversity. Water is also essential for the survival of all living organisms, but unfortunately sources of water used in industries are suffering from all kinds of pollution. The aim of this study is to review the level of food contamination with toxic heavy metals in world. This study was a descriptive overview with entry criteria, relevant information and the keywords of the research.

Heavy metals such as Zn, Pb, Fe, Ni, Co and Cu are abundant in the environment and contribute greatly to the stability and balance of ecosystem processes. However, the fact that they are in excess pollutes the food chain and then becomes a source of poisoning for humans and the entire ecological function. This is an important problem in the study of ecology and geochemistry.

The article develops an algorithm for assessing the bending resistance of yarns of suit embroidered fabrics, on the basis of which the theory of displacement of cross-sections of the free part of the yarn is determined experimentally by the bending stiffness of Arqaq yarns with different weaving and fiber content. The reasons for the appearance of various irregularities on the surface of the suit are shown. It was found that the properties of Tanda and Arqaq yarns depend on the natural properties of the fibers, their length, the technological properties given during the spinning process.

The plan of rough terrain vehicles is muddled. Especially when the driving, is went with another
assignment, at the same time. Such an intricate situation may prompt human mistake and end up with
a mishap. The writing recommends three consolidated and significant angles, in vehicle structure:
vision control, anthropometrical fitting and biomechanical contemplations. No examination is
discovered which underpins a rough terrain vehicle plan from every one of the three viewpoints
together. Likewise, the broad utilization of PC supported structure (computer aided design) in the

test ergonomic exploration, of a rough terrain lodge structure. The exploration asks the three
aspects,combined, creating quantitative outcomes. These outcomes produce a superior fitted
structure to the administrator and his operational needs, which help the specialist to plan a cabinthat
may prompt less exhausting sitting stances and weakness.

Population growth, the compact location of villages and towns around cities, the creation of jobs on
their territory makes the construction of affordable housing in rural areas relevant. In order to
improve project management, in particular, to create a single platform that unites the efforts of
construction participants and further reduce the cost of projects, a methodology has been proposed
for developing a schedule for the construction of a complex consisting of an array of residential
buildings, social infrastructure and linearly extended structures. The resulting schedule can be used
to conclude contracts between construction participants and clarify financing schedules, start and
end dates of stages, supply of material and technical resources to the construction site.

The current economic situation forces copper smelters to refuse to process man-made waste (slags, dusts, cakes, etc.). Lead-and zinc-containing solid waste accumulates in significant quantities on the territory of factories, in so-called “temporary " dumps, and is often stored on the sites of enterprises. Attempts to sell lead-containing industrial products encounter difficulties related to low prices on the part of lead monopolists, problems with the preparation and transportation of industrial products, environmental and other restrictions.
