Dynamics of Microbiological Diversity of Soils in the Chu Valley during Land Use Change in Pastures

Nurzat TOTUBAYEVA

Soil microflora is one of the first to feel a negative impact and can serve as a biological indicator of changes in the soil structure and the degree of impact on the soil ecosystem. In 2020, studies were carried out at two sites located in the Shamshy Gorge in the Chui region of the Kyrgyz Republic. One of the plots was withdrawn from pasture use for one year in 2020 and two years in 2019 as compared to the actively used control option. The microbiological diversity was studied with conventional methods of microbiology. The micromycetes of the studied soils were represented in the dominance o ...Более

New Voltammetric Approach to the Quantitation of Paracetamol in Tablets and Syrup using Chemometric Optimization Technique

Ali Osman SOLAK

A new voltammetric approach was developed for the determination of paracetamol in tablet and syrup samples using chemometric optimization. The method is based on the use of the gold nanoparticles-polyaniline (AuNPs-PA) modified pencil graphite electrode (PGE). Electrode system was fabricated by using the electrochemical reduction of gold on aniline modified pencil electrode to give gold nanoparticles. A 3(3) full factorial design was used to find optimal oxidation conditions of paracetamol on the AuNPs-PA-PGE. The optimal oxidation conditions of drug substance were found as -524 mV for the acc ...Более
