Salohiddinov Fayzulloh Fazliddin o’g’li — 2024-05-04

Supervisory Control and Data Acquisition (SCADA) systems play a crucial role in the efficient operation and management of wastewater treatment facilities. These systems integrate various technologies to monitor, control, and optimize the complex processes involved in treating wastewater. Here's an overview of the SCADA system in wastewater treatment:

GET TO KNOW THE TYPES OF RICE DRYING EQUIPMENT

Olimov Bobir — 2024-05-08

Currently, great attention is paid to energy-saving devices, including energy-saving grain dryers. In addition, the issue of improving the quality of drying and accelerating the drying process is still relevant. One of the most important aspects of improving the dryer is combining the benefits of multiple dryers to create combined energy efficient dryers. This article examined energy-efficient rice dryers as well as the available literature. Combines all relevant information for drying rice and for comparison by technology. Energy for a number of drying technologies, consumer data is summarized from published literature and normalized for comparison. Performance indicators are given in the industrial or laboratory conditions in which a large part of the source data is created. Our analysis shows that combined grain dryers reduce drying time compared to other types of dryers as well as provide quality drying. Combined grain dryers usually have high energy efficiency when drying steps are included.

STUDY OF IR AND THERMAL ANALYSIS OF MODIFIED POLYVINYL CHLORIDE

Akhmedov Furkat Bakhtiyorovich — 2024-05-08

Fire retardants based on polyphosphate ammonium-containing metal oligomers have been obtained. When comparing the IR spectroscopic analysis of the sample under study with analogues, it was found that the characteristic relationships are close to each other. Based on the results of DTA and TGA analysis, kinetic parameters were determined for various temperature ranges of the process. Its advantage is based on the experimental data obtained on the kinetics of processes in the temperature range from 100°C to 600°C; the properties of thermal-oxidative destruction of samples with 5-30% fire retardants have been studied.

MATHEMATICAL MODEL OF THE EFFECT OF MODIFIERS ON GRAY CAST IRON ALLOYS

Jamshidbek Khasanov — 2024-05-15

This article presents a research analysis of the effect of the CuP2 element as a modifier on the wear resistance of the gray cast iron low – alloyed liquid cast iron alloy. Based on the obtained results, the increase in the number of crystallization centers of the cast alloy and the formation of a fine granular structure led to a significant increase in the wear resistance property of the cast product.

SOME PROCEDURAL ISSUES RELATED TO THE PARTICIPATION OF AN INTERPRETER AS A PERSON ASSISTING IN THE ADMINISTRATION OF JUSTICE IN CIVIL PROCEEDINGS

Davlatjon Khabibullayev — 2024-05-17

This article presents a scientific and theoretical analysis of the issues of improving the procedural norms related to the participation of the interpreter as a person assisting in the administration of justice in civil proceedings. Also, the procedural rights and obligations of the interpreter in the civil process, the expenses paid to him, and the civil procedural laws of foreign countries were compared with the national civil procedural laws. Scientific-theoretical conclusions, proposals and recommendations aimed at improving the norms related to the participation of an interpreter in civil proceedings have been put forward.
