The article presents an improved scheme and pilot-industrial copy of a flat reflector solar air heating collector with heat accumulator. balance equation the accumulator is constructed, its energy efficiency based on it. Considering local climatic meteorological characteristics city Karshi, useful performance coefficient was determined experiment conducted This designed device proposed as activ...

In this article, the scientific and practical basis of geodetic topographic work in design hydraulic structures solutions intended to improve them using GIS (Geoinformation Systems) were analysed. Geodetic works are for design, construction reconstruction Uzbekistan. A systematic approach analysis was chosen, which used determine essence processes laws substantiation projects various structures...

The length of the rivers in Uzbekistan and presence all biotopes mollusks have made they a favourable reservoir for mollusks. However, it should be noted that species differ their density. Rivers fishery farms play great role formation bivalve fauna canals. It was studied Syrdarya River its surroundings major effect on Mirzachul South canals; Zarafshan River’s spreading Dargom Eskiankhor Amudar...

The demand for natural fibers such as silk, wool, and cotton is growing globally, especially silk fabrics raw materials from cocoons. In nations with well-established sericulture, efforts are concentrated on enhancing the quantity quality of cocoon production by high-nutrition-value mulberry varieties through asexual reproduction. study aimed to determine productivity hybrids during double oper...

The article presents the results of a study wear individual pump elements, decrease in their efficiency and significant losses. nonidentical operation extreme middle pumps was established. uneven approach water to units created reverse flows suction pipes, work with vibrations modes close cavitation. modernization improved cavitation characteristics due elimination center at impeller inlet area...

In the arid areas of river itself, direction flow is characterized by changes depending on its hydrological regime. As a result these changes, can be branched into several streams and distributed differently in terms quantity. passes through lightly washed soils, have different depths, hydraulic elements morphometry vary at intensities. Changes resistance as such affect water permeability strea...

Gwarimpa, Garki, Gui, Gwagwa, Karu, Karshi, Nyanya, and Kabusa blocks for research. To...

The purpose of diagnostics is to determine the operability pumping units station machine water lifting at a given time and identify defects in their components. For this reason, article presents diagnostic issues for stations No. 1 - 6 Karshi main canal, designed commissioned 1965-1976, where OPV11-260EG type with electric motors VDS-375/130-24 are installed, vertical units, shaft power – 8010 ...

Flaviviruses are a highly diverse group of RNA viruses classified within the genus Flavivirus, family Flaviviridae. Most flaviviruses are arthropod-borne, requiring a mosquito or tick vector. Several flaviviruses are highly pathogenic to humans; however, their high genetic diversity and immunological relatedness makes them extremely challenging to diagnose. In this study, we developed and evalu...
