Abstract:

The paper covers the causes of occurrence and the methods of investigating soil acidity in Kozova destrict, Ternopil region. It is a highly topical issue, since increased soil acidity negatively influences the growth and the development of most cultivated crops and affects favourable microbiological soil properties. Soil acidity is caused by hydroions that are formed under the dissociation of acids and hydrolytic acid salts and are absorbed by the smallest soil particles – colloids, which can go into interstitial water. The increased soil acidity, which is a limiting factor for the biodiversit

Introduction. The problem of processing waste from the mining and metallurgical complex of the Republic of Kazakhstan, including manganese ore processing waste, is relevant both from a technological (expanding the raw material base and assortment of marketable products) and from a geoecological (minimizing waste, preserving resources and the environment) point of view. The purpose of this work is to study the possibility of processing manganese ore processing waste from some deposits in Kazakhstan into phosphating solutions. Results and discussion.

Abstract Background: The mineral oil has been widely used in a power transformer for the purpose of insulation and suppression of corona and arcing. But due to its extremely low flashpoint, this can also cause an explosion in the case of a fire and the mineral oil has been found to be non-biodegradable. In this research, an alternative of mineral oil is proposed, which is the usage of used cooking oil which will undergo chemical modification via transesterification in order to achieve its expected properties which fits into the requirements of the power transformer according to the IEEE standa

Improvements to the routine methods for the determination of actual acidity in suspension for acid sulfate soils (ASS) are introduced. The titratable sulfidic acidity (TSA) results using an improved peroxide-based method were compared with the theoretical acidity predicted by the chromium reducible sulfur method for 9 acid sulfate soils. The regression between these 2 measures of sulfidic acidity was highly significant, the slope of the regression line not significantly different from unity (P = 0.05) and the intercept not significantly different from zero.

Abstract:

The present investigation was conducted to understand these parameters, which form an integral part of a programme for making improvements in snake gourd yield and its contributing characters. The present investigation was carried out with 32 snake gourd genotypes during late kharif 2021-22. There was need for more genetic research because the genotypes for every character under study differed significantly. Average fruit weight, fruit yield per vine, number of seeds per fruit, node to first female flower, fruit length, fiber content, acidity content, and potassium content all showed high valu

Abstract:

The notion of yoghurt's positive impact on human health and nutrition has been widely held throughout several civilizations for a considerable duration. The aim of this study is to examine the benefits of adding oat beta glucan to skim milk in order to enhance the production of yogurt. An investigation was conducted on yogurt samples to analyze their physicochemical properties (pH, titratable acidity, syneresis, water-holding capacity (WHC), and hardness) as well as their sensory qualities. The samples were stored at a temperature of 4±1 °C for 1, 7, 14, and 21 days. The analysis revealed that

The purpose of the study was to comprehensively analyse the effectiveness of environmental indicators in determining the state of forest ecosystems and their ability to reflect changes in the ecological balance. During the study, the influence of anthropogenic factors on biomass, soil acidity, and species diversity of forest ecosystems in the Sumy Oblast of Ukraine was evaluated. Field studies were conducted to determine the soil acidity, the biomass of plants and animals in anthropogenic and natural forest areas, followed by statistical analysis of the data.

Abstract:

This research aimed to examine how varying the acidity levels during the chemical oxidative polymerisation (COP) of aniline affects the colour, yield, morphology, and surface functionalities of polyaniline (PANI). In the COP method, aniline monomer was first dissolved in hydrochloric acid (HCl) medium; the solution was then drop added with ammonium persulfate to initiate the polymerisation process. To answer the research objective, the medium acidity was manipulated using different concentrations of HCl (i.e., 0 M, 0.01 M, 0.1 M, 1 M and 10 M). The as-synthesised PANIs were then purified and c
