Planning Of Experiments And Description Of Instruments Used For A Device That Ensures Microclimate In Poultry Buildings

A. B. Sattarov — 2024-11-06

Based on research conducted to ensure optimal microclimate parameters in poultry buildings, a plan and sequence of tasks were developed for conducting experiments on processing and cooling the external air parameters supplied to the newly created device. As a result of research on ensuring optimal microclimate parameters in poultry farms, a plan and a sequence of tasks were developed for conducting experiments to process and cool the parameters of external air supplied to the created device. After normalizing the temperature and humidity indicators, modern measuring instruments with high reliability of measurement results were selected to determine the operational efficiency of the equipment. Various outdoor air parameters were adopted to assess the equipment's performance under different conditions.

Investigation Of The Influence Of Pressing Rolls In Extending Mechanisms On The Number Of Yarn Breaks In The Technological Process Of Yarn Spinning

S.Kh. Bobojonov — 2024-11-07

In this article, the effect of the pressing rollers in the stretching mechanisms on yarn breaks during yarn spinning is studied. The mechanical properties of the pressing rollers and how their loading affects the strength and quality of the thread have been studied. In the course of the research, practical recommendations were developed to reduce thread breaks and optimize stretching mechanisms

Implementation of New Technologies in the Water Supply and Wastewater Discharge System

Razokov Sardorbek — 2024-11-10

In the article, the water supply system, water intake facilities within the complex of its facilities, water preparation and delivery to consumers are considered important. The efficiency of the system is ensured by increasing the efficiency of water intake facilities, and this requires modern technologies. Sewage networks are used independently. Therefore, the pipes are laid with a certain slope. In order to be convenient from the economic point of view, the preferred form of sewage networks should be chosen.

Methodology For Inspection Of Elevator Systems After Strong Earthquakes And Their Field Testing Under Dynamic Loads

Olimkhon Khondamir — 2024-11-16

The study outlines a methodology for inspecting elevators after earthquakes and conducting field tests to assess their dynamic characteristics. The tests are carried out in two stages: sudden load release and vibrational impact. Seismometric equipment is used to measure displacements and accelerations of both the elevator and the building. This method helps identify the impact of building design features on elevator performance and enhances their safety in seismically active regions

Creating Mixtures Similar To The Original By Modifying Gypsum For The Restoration Of Architectural Monuments

Inomjon Tojiev and Javohir Ilhomov — 2024-11-23

The article contains the findings of research on the historical approach used to build the mausoleum of Ismail Samani and the Kalyan minaret. It is revealed that calcium sulfate is mainly used in the compositions of the solutions. These historical solutions are also modified with organic and mineral additives. Based on chemical, differential-thermal analysis (DTA), reed analysis revealed that reed ash, chickpea flour and lime were used in these solutions. Considering the analytic findings, we synthesized the combinations of modified compounds based on local gypsum. The composition along with technology for obtaining converted solutions for the instauration of old city's architectural landmarks of Bukhara have been developed. The developed composition of the modified solution is put into practice. The research demonstrates that the structure and strength of the modified gypsum-based solution are virtually identical to the structure of the mortar used in national architectural monuments

Optimization Of Parameters Of A Rod Intensifier Of A Potato Digger With The Method Of Mathematical Planning

Juraev Bakhodir Botirovich — 2024-11-23

In this article, the method of mathematical planning of multifactorial experiments is used to determine the optimal values of the parameters of a potato digger equipped with an elastic rod intensifier, obtained in single-factorial experiments. It is assumed that the influence of factors on the evaluation criteria is fully explained by a second-order polynomial, and the experiments were carried out according to the Hartley-4 (X4) plan
