Zoning of the Territory of the Republic of Kazakhstan by the Degree of Intensity of the Epizootic Situation on Plague in Camels

The aim of the study was to improve epizootiological monitoring and increase the effectiveness of preventive (anti-epidemic) measures for camel plague control in Kazakhstan.Materials and methods. We used the data on epizootiological and epidemiological monitoring in natural plague foci of Kazakhstan, long-term measurements and indicators for the period of 2000–2020 of the anti-plague and veterinary services of the Republic for the analysis. To process the evidence, epidemiological, epizootiological, microbiological, and statistical research methods, as well as GIS technology were applied.Results and discussion. The number of camels has increased by 2.2 times in Kazakhstan over the past 20 years.  Where there were 98.2 thousand heads in 2000, it amounted to 216.4 thousand heads in 2020. Over the past 10 years, 152 camels died of unknown causes in the focal area of the country, but laboratory tests for plague turned out negative. According to the hazard criteria, the territory of the country has been conditionally divided into three zones: five regions with a high degree of hazard with a total area of 953.15 sq. km, five regions with medium degree of hazard with a total area of 1230.72 sq. km, and with a low degree of hazard – four regions and three cities of republican significance with a total area of 541.1 sq. km. Constant epizootiological monitoring over plague in camels is a necessity for the system of preventive measures

Fabrication and characterization of electrospun PVAM/TEOS based gel polymer electrolyte for Lithium-ion batteries

Gel polymer electrolytes (GPEs) are promising components in lithium ion batteries (LIBs) because of leak proof, longer shelf life and safety. GPE consists of a porous polymer host and liquid electrolyte saturated within and combine the advantages of both the liquid and solid components [1]. In this study, a GPE based on poly(vinyl alcohol)/maleited PVA/tetraethyl orthosilicate (PVA/PVAMA/ TEOS) polymer fibers were prepared in different weight ratios. Crosslinked nanofibrous polymer membrane for GPE was fabricated by UV-electrospinning method. Dual crosslink polymer membranes were obtained after heat treatment of as-prepared polymer nanofibers, due to the condensation of hydrolyzed TEOS. The morphology of the electrospun membranes was studied using scanning electron microscopy. Thermal properties of the membranes were investigated using thermal gravimetric analysis. The membrane has good porosity exhibits high uptake when activated with the liquid electrolyte of lithium salt in a mixture of organic solvents and also shows high liquid retention properties. Electrochemical impedance spectroscopy and linear sweep voltammetry was used to determine the conductivity and electrochemical stability of prepared GPEs. Electrochemical performance of the polymer gel electrolyte is evaluated in Li/polymer electrolyte/LiFePO4 coin cell

Absorption of Water Vapor by Bambus[6]uril and a Density Functional Theory Study of Its Aqua Complexes

The absorption/desorption of water vapor by bambus[6]uril (Bu[6]) has been studied. According to kinetic experiments, the absorption capacity of Bu[6] is 4 moles of water per 1 mole of Bu[6] with the absorption duration of 20 min and the complete desorption duration of 100 min. Experimental rate constants for water vapor absorption and desorption by Bu[6] have been determined to be 0.166 min−1 and 0.0221 min−1, respectively. The obtained results are in agreement with theoretical calculations using the DFT method. A hypothetical structure of bambus[6]uril tetrahydrate (Bu[6]·4H2O) has been proposed based on the experimental and DFT data
