In this study, poly(2-hydroxyethyl-sodium methacrylate) (p(HEMA-SMA)) hydrogels were synthesized as a novel adsorbent to remove antibiotic residues from environmental samples. [p(HEMA-SMA)] co-polymers were synthesized by the free radical photopolymerization method. Synthesized hydrogels were characterized by different methods such as Fourier-transform infrared spectroscopy (FTIR), elemental and scanning electron microscope (SEM), and surface area calculations. The average size surface area of the synthesized hydrogels were 1.515 µm. Penicillin G (Pen. G) was used as the sample antibiotic for ...More
The sugar beet processing in the sugar production industry releases huge amounts of sugar beet pulp, lime residue, and molasses, which can be considered a valuable by-product as a source of cellulose, hemicellulose, and pectin. Sugar beet pulp is often used as a high-energy, low-protein supplement for ruminants to promote optimal rumen health and increase milk production. However, it cannot be used in large quantities and is thrown away, causing environmental pollution. Valorizing sugar beet processing wastes via biotechnological approaches into value-added products is cost-effective and eco-f ...More
In this paper, we represent a numerical method to solve linear and nonlinear integro-differential equations system. By this method, we can find the solution of the system by power series and reproduce the analytical solution if the exact solutions are polynomial, otherwise we find their's Taylor series. The comparison of the approximate solution and exact solution shows that the used method is easy and practical for linear and nonlinear integro-differential equations system. The package Maple 13 is used for computation.-

The aim of the research is to analyze the diagnostic results of infected people with the COVID-19 in Bishkek. Therefore, in this study, with the aim of epidemiologically analyzing the COVID-19 infection in the city, diagnostic PCR research was carried out at the Center for Quarantine and Highly Dangerous Infections of the Ministry of Health of the Kyrgyz Republic in the Laboratory of Virology and Rare Infections. During the period of operation from 01st May 2020 to 31st March 2021, 28,863 samples from patients of the Sverdlovsky and Pervomaisky districts of Bishkek were examined by the real-ti ...More
В статье обсуждается общность и различия подходов курсов физики и теоретической механики к изучению колебательного движения. Учитывая достаточную распространенность инженерных задач, связанных с колебательными процессами, поднимается вопрос о необходимости включения данного раздела в программу курса теоретической механики для инженеров. При переходе от начальных представлений о колебательных движениях, полученных в курсе физики к изучению их на теоретическом уровне, в рамках Лагранжева формализма, целесообразно для начала сформировать у студентов умения и навыки составлять и решать уравнения д ...More
