Published: May 2023

This article deals with the development of a new composition of a polymer composition for dressing cotton yarn. The optimal concentration of the dressing polymer composition, which is 50 g/kg, against the starch-based dressing is 70 g/kg, i.e., the consumption of starch is reduced by 25-30%. It is experimentally established that the concentration of the dressing, which has a significant impact on the cost of the dressing, varies within 45-50 g/kg of the composition, while the true glue remained at the same level.

Authors: Dusmatov Olimjon , Urunboev Erkin , Mamatkabulov Abdumajid
Published: May 2023

In this paper, the problem of developing a mathematical model of rectilinear motion of a car is solved, taking into account the elasticity and deformability of tires, as well as, for the same radii of the wheels of the car, and taking into account plane-parallel motion at a constant speed. The kinetic energy of the rectilinear motion of the car is found in the case of the same rotation of the front wheels around the axis of the pivots. Generalized forces are taken as sum of forces acting on the system and forces due to the deformation of the pneumatics. The forces acting on the system are found by virtual work method. The forces due to the deformation of the pneumatics are found as the generalized forces acting on the system under consideration, in the calculation of which all forces are taken into account, except for the tire deformation forces associated with angles and displacements. Using these kinetic energies and generalized force expressions, Lagrange's equations of the second type were used to obtain the differential equations of the rectilinear motion of the car. From the resulting mathematical model, it is possible to check and analyze the dynamics and stabilities of the system in various specific cases, i.e., under the influence of non-potential forces in the tire materials, and at large values of the tire kinematic parameters, and at high speed movements of the car. As a result of determining the stability field and stability borders at different values of constructive parameters, it will be possible to find the optimal parameters of the system and study its dynamics.

Published: May 2023

The non-homogeneity in mass and geometrical parameters of leather of one type and one manufacturing method is experimentally investigated and analyzed. Experimental studies were conducted on semi-finished cattle products of a combined batch and chrome kips from one technological batch. The results of the experiments showed that with a combined batch, between the mass and thickness of the leather semi-finished product, there is a moderate correlation between the studied physical parameters and the average error of the correlation coefficient of the leather. It is determined that high correlations are expressed between the mass and area of the leather, and between the thickness and area of the leather, respectively. It was revealed that the samples of leathers selected for experiments (kips), depending on their type, weight and area, have a higher correlation. So, between the mass, thickness and area at the standard point of the kip, there is a higher correlation between the studied physical parameters of the semi-finished leather samples. The results obtained provide an opportunity to influence the properties of leather for further creation of methods of controlling the relevant devices and equipment at various stages of production processes.

Evaluation of mechanical properties of metal plates with protective coatings
Authors: Farmakovskaya A.A. , Okorokova N.S. , Perchenok A.V.
Published: May 2023

In this paper experimental and computational results obtained by numerical simulation of uniaxial tension of 0.7 mm thick metal plate specimens are compared. The Digimat-FE (MSC) system was used for modelling, which in numerical calculations uses the finite element solver of the Marc (MSC) software package. It is shown that for specimens without coatings the found theoretical values of critical load correspond quite well to the points on the experimental diagrams, at which the dependence of load and displacement ceases to be linear. For coated specimens, the critical loads turn out to be considerably lower, and for their description, it is necessary to obtain a refined estimate taking into account the action of residual stresses.
Experimental estimation of liquid phase concentration in aerosol jet
Authors: Goltsman Anna
Published: May 2023

Rapid-mixed models are a key tool in the numerical solution of aerosol flow evaporation problems. Despite the fact that these models are mainly based on analytical arguments, they have shown fairly good reproducibility in practice. However, with the advent of the DNS results, cases of discrepancies with the classical theory of droplet evaporation began to be discovered, which require an experimental study of the problem. The present paper shows an experimental method for estimating the concentration of the liquid phase in aerosol flows based on digital video processing.

Authors: Ushkov Valentin , Smirnov Vladimir
Published: May 2023

The increased fire hazard of foamed polymers hinders their widespread use in the construction industry. An effective method of reducing the combustibility of carbonizing polymers is the use of phosphorus-containing flame retardants. Therefore, investigation of the influence of phosphorus-containing flame retardants to the composition of pyrolysis products and operational properties – heat resistance, flammability, combustibility and smoke generating ability – is the important objective. In the article we have presented the results of related experimental studies. The effects of phosphorus-containing flame retardants on heat resistance and main operational properties related to fire-safety of foamed constructional polymers are examined. A correlation was found between the results of evaluating the combustibility of foams by the limiting oxygen index and the combustibility index. Optimal concentrations of phosphorus in the foamed thermosetting polymers are established. It was shown that optimal concentration of the flame retardants leads to low combustibility of polyurethane-, resole- and urea-based foamed polymers.

Authors: Farmakovskaya A.A. , Okorokova N.S. , Perchenok A.V.
Published: May 2023

In this work a study of nanoindentation of the surface of epoxypolyester-based powder coatings deposited on steel substrates was carried out. The effect of the test method on the identifiable mechanical properties is investigated. The measurement results obtained by using a spherical indenter and a Berkovich indenter are compared. Estimates of reduced modulus of elasticity, Young's modulus and rigidity of coatings are obtained. The experimental data obtained indicate a significant dependence of the determined mechanical properties of the paint and varnish coatings depending on the type of indenter used. In the case of Berkovich indenter, the Young's modulus of coatings (0.6 GPa) is understated in relation to coating properties known from macro experiments (3 GPa). Using a spherical indenter, Young's modulus is overestimated (6.3 GPa).

Published: May 2023

The article analyzes the designs of various types of cultivators, which are used to remove unwanted herbaceous and tree-shrub vegetation. Cultivators with disk, rotary, milling and tine working bodies are considered. It is shown that quite a lot of material resources are spent on carrying out agro technical care for valuable forest crops. It is noted that the mechanical method of soil care in the aisles and rows of forest crops has become widespread, despite the high costs. It was found that the rotary cultivators KRL-1M and KBL-1 during their movement cover seedlings up to 15 cm high with soil, and in plants 40-50 cm high and higher, when saddling a row, the apical bud breaks off, the bark is peeled off, side branches break. Damage to forest crops is about 8%. Damage and destruction of cultivated plants by the KRT-3 cultivator is 30%, and by the KFL-1.4 cultivator - 43%. Cultivator KRT-3 has low reliability. When meeting with stumps, the racks of the working bodies and wheels are deformed, and the paws are often broken. The milling cultivator KFL-1.4 also has low operational reliability.

This paper seeks to contribute to continuing efforts to better understand and control the effects of urbanization on our environment and society by offering a thorough review of the most recent geodetic measuring techniques for build-up area growth. In this article, we give a case study from Uzbekistan that looks at current geodetic measuring techniques for expanding build-up areas. Uzbekistan is a fast urbanizing nation in Central Asia, and politicians and experts are both deeply concerned about the growth of the country's built-up regions. The case study, which offers a thorough investigation of the geodetic measuring methods and tools used to gauge and track the growth of the built environment, is focused on a particular metropolitan region in Uzbekistan. Therefore, this article gives a summary of current geodetic measurement methods, including remote sensing methods like LiDAR and satellite imaging as well as surveying methods like total station and GNSS. The case study also emphasizes some of the difficulties and restrictions related to these methods, such as the requirement for precise geodetic control points and the inadequacies of satellite imaging in regions with thick vegetation or cloud cover.
Variability of the growing season period in F2-F4 hybrids of cotton in different soil-climate zones of Uzbekistan
Authors: Egamberdieva Saida
Published: May 2023

One of the most crucial topics in cotton breeding is the identification of plant reactions to the environment, including its stressful circumstances and the amount of plant responsiveness to biotic and abiotic stimuli. Plants continuously interact with their environment as they grow and develop; this interaction results in the organism's ability to adapt, or adaptation. For the duration of the plant's existence, the process of adaptation never comes to a stop. The most crucial evolutionary component that enables the adaptability of species and populations to changing environmental conditions is variability, a feature of an organism that represents the processes of its interaction with the environment. Variability is the foundation of adaptation. An assessment was made of the variability of the length of the growing season in four hybrid combinations of medium staple cotton in 2018-2020 in the Tashkent, Fergana and Kashkadarya regions of the Republic of Uzbekistan. It has been established that the duration of the growing season depends mainly on the geographical latitude and genotype of the plant: in the more northern growing zone (Tashkent region), both the average length of the growing season and the amplitude of the trait variability increase compared to the indicators in the Fergana and Kashkadarya regions.

The use of a composite defoliant in various norms of Bukhara-8 cotton in the Bukhara region is considered. Identified from 10 options that had a positive impact on the efficiency of defoliation, productivity were - (Mg (ClO3)2liq. 4 l/ha + Fitovak 75 ml/ha + Urea 6.5 + Humin-1.5 kg/ha). The weight of the bolls, the weight of the 1st collection, the gross yield were higher with the control, the standards were respectively heavier by: 0.7-0.9-0.8 g and 4.5-3.7-2.8 c/ha; 5.9-2.2-3.1 q/ha yield increase. The defoliant rate was reduced by 50%, the accumulation of Cl-, MgCl2 salts in the soil, air up to 50%, the ecological environment was saved from damage to the ozone layer Cl- by a certain amount, which affected air pollution. Boll burns under the action of the composite defoliant were not observed, due to the formation of a conductive layer between the leaf and stem, which activates the endohormone triggers contained in Fitovak in plants. The flow of nutrients into the stem to the bolls, bypassing the leaf, through the stem leads to an increase in the mass of the 1st, entire crop and the rate of opening of the bolls.

Authors: Rakhmonov Ubaydillo , Soatov Tolib
Published: May 2023

Extended cultivation of Pleurotus ostreatus in the same location leads to increased infection by harmful organisms, which results in reduced yield and quality of the mushrooms. This, in turn, decreases the profitability of production and may render mushroom growing an unviable industry [1-4]. In blocks infected with harmful competing microorganisms, the growth of P. ostreatus mycelium is initially very slow, and the blocks lose their quality due to the influence of foreign microorganisms. Extended cultivation of Pleurotus ostreatus in the same location has been observed to result in an increase in the incidence of harmful organisms, leading to a decrease in the yield and quality of the mushrooms. xperiments were conducted to investigate the impact of foreign microorganisms on the growth, development, and yield of Pleurotus ostreatus using cotton bolls, a substrate that has proven to be effective in the Republic. According the results, the appearance of Trichoderma fungus in the substrate blocks was observed 7 days after sowing P. ostreatus, with colonies forming that were 2-3 cm in diameter. These indicators were observed in 12.7% of the total number of planted blocks. After 14 days, the percentage of blocks with Trichoderma lesions increased to 18.4%, with moderate damage being the most common.

Published: May 2023

The current trajectory of the global transportation system is widely acknowledged to be unsustainable. Many people think it's time for a radical shift in how things are done, how things look, how money is spent, and so on. New technologies will have varying long-term negative implications across all cultures, developed and developing alike. The growing interest in the alternative method to sustainable development may be attributed to the convergence of concerns about environmental quality, social equality, economic viability, and treatment of climate change due to rising CO2. Because sustainable growth is crucial for the future of any era, but particularly in this century, it deserves a lot of attention in this article. Society, the economy, and the environment are the three main components of sustainable development in the transportation industry. Sustainable transport needs equilibrium between these three areas to meet its minimum requirements. The importance of transportation to sustainable development must be bolstered by implementing sustainable practices. These tactics include public transportation advocacy, demand management, better road management, pricing regulations, vehicle technological advancements, the use of clean fuels, cultural enrichment, and transportation planning. In this research, we assess how transportation factors into sustainable development initiatives and what impact such methods have.

Advantages of light-optical devices (LEDs) were investigated in the article. Based on the research, special attention is paid to the prospects of development of led headlights. Complicacy of car electrical equipment leads to increase of indicated efficiency and energy storage capacity and electric generators, yield increase, decrease of labor intensity maintenance operation and reconstruction. On the other hand, innovations in scientific-technological progress in electronic engineering sphere lead to rise in reluctances, so more than 30% of these reluctances account for electrical equipment. Analysis of current requirements to automobile components of lighting devices has been carried out. LEDs as automobile light sources are gaining rapid popularity. Currently, LEDs are widely used as internal light sources (instrument illumination, indicator lamps) and external ones (tail lights, additional brake lights, daytime running lights). Since 2007, white LEDs have been used as dipped- and main-beam sources. Light sources are characterized by such parameters as voltage, light power and luminous power. Derivative of these parameters is the luminous efficiency (luminous power per unit of light power), that acts as a kind of lamp’s performance and economy indicator. This article has been made in relation to the study of auto technical expertise in Moscow and Moscow Region.

Movement strategies selection of a mobile robot to avoid obstacles
Authors: Alkhaleeli A.S.B. , Lukyanov E.A.
Published: May 2023

The movement of a mobile robot in a non-deterministic environment is accompanied by maneuvering due to the need to avoid a collision with a fixed or moving obstacle. Under certain conditions, several obstacles, including moving ones, may appear in the near zone of the robot. In this case, trajectory-planning algorithms based on a “static” approach to the position of obstacles will not be effective; their application may lead to collisions. Finding the path of movement in conditions of dynamic obstacles is an urgent task that researchers are trying to solve using various methods. The article proposes a method for planning the actions and movements of a mobile robot in non-deterministic conditions, in the presence of fixed and moving obstacles. The processes of planning the trajectories of a mobile robot in the presence of obstacles in the near zone are considered. Methods and algorithms for making decisions on avoiding obstacles based on the estimated collision probabilities in the forecast interval are proposed.
