Isomeric Properties of Organic Compounds

/in /by

Organic compounds have different linear and branched elaborate formulas, so if two organic compounds with the same molecular formulas and different elaborate formulas are called isomers of each other. The same but differs in structural formula and physical properties is called isomerism and the phenomenon is called isomerism. Spectroscopic research has shown that the chemical and physical Properties change and new materials emerge with new properties, but the change in the position of the bonds within a molecule only causes a change in the physical properties and leads to the formation of isomers.

Review of the Effects of Water Characteristics and Quality on Human Health

/in /by

This paper reviews water quality parameters and their health effects on humans with the objective of enlightening the public on drinking water guidelines, the focal point and protection measures. It is also intended to help evade the health catastrophe that manifests as a result of ingesting water containing substances in excess concentration of recommended limits. Sources of water are reviewed, including rain water, surface water and groundwater. The presence and level of the biological, physical and chemical constituents referred to as water parameters which determine its suitability for drinking were also reviewed. Biological parameters are microorganisms, while physico-chemical parameters include temperature, color, dissolved solids, cations, etc. Drinking water quality standards as well as the health impacts of water quality parameters were discussed. Some of the health impacts include water borne diseases, organ failures, cancer, neurological damage, etc. The paper concludes that microorganisms and chemical constituents in drinking water sources and supply can directly or indirectly impair the use of the water for human consumption. Recommendations were made including the disinfection of drinking water sources to prevent growth of disease causing organisms, hand washing to prevent infections including Covid 19 virus and laboratory assessment of water quality parameters to ascertain their conformity with drinking water standards.

/in /by

Financial integration can improve the efficiency of capital allocation as well as help diversify risks. This study aims to find and analyze four cases. First, to find and analyze the long-term cointegration between East and Southeast Asian. Second, to find and analyze the short-term causal relationship between East and Southeast Asian equity market. Third, to find the most influential equity market from East Asian toward their Southeast Asian and the most influential equity market from Southeast Asian toward their East Asian. Last, to find the forecast structural analysis for five days horizon period of each country’s price, both East and Southeast Asia. This study uses Johansen’s cointegration method to test long-run relationships between East and Southeast Asian equity markets, Granger-causality, forecast variance decomposition method and forecast with VECM. This study uses daily indices prices collected from Refinitive covered from January 2002 to December 2019. Johansen’s test emphasize that there is a cointegration relationship between East Asian and Southeast Asian stock markets, but the integration process is incomplete.

Investigation of Expectation Gap between Auditors and Investors in Bangladesh

/in /by

The goal of this study is to determine the variable(s) that is/are sources of audit expectation gap between auditors and individual investors (i.e., financial statement users) in Bangladesh. The variables used are Internal Control, Fraud Detection, Appropriateness in using accounting numbers and lastly Reliability. In this research the sample size was selected purposively, a total of 30 auditors were selected from different audit firms in terms of firm’s size, revenue, and practices again a total of 30 investors were selected purposively. A structured format of questionnaire was used where the response options were predetermined to acquire information directly from auditors and investors. The questionnaires consist of two sections, first section collected demographic data and second section enclosed 12 semantic differential belief statements. Same questionnaire was given to two independent sample groups (auditors and investors) to identify expectation gaps. To identify the variable(s) that are the cause of the audit expectation gap, the statistical approach “Independent sample t-test” was used. The disparity between auditor and investor in two variables, internal control, and reliability, is discovered in this study. The reasons behind these gaps are lack of proper educational practices and lack of understanding regarding audit norms and practices. These gaps can be reduced by giving adequate knowledge, awareness, and fair practices by the auditors to the financial users.

The potable water status is very poor in case of rural areas, where there is an immediate requirement of sufficient and secure potable water. The purpose of the present study is to assess knowledge, attitude and practices regarding water storage and purification practices as possible determinants of diseases in the rural population around Kolhapur city. Women members which are chiefly related to household water were interviewed using questionnaires in 6 villages in Karveer district. The study showed that all households stored drinking water in containers. Though many water purifying gadgets are available in market, the rural population is deprived of these treatment options, either due to unawareness or poor economic conditions. Improper storage practices at household level can aggravate the problem of drinking water contamination. It was observed that Point of Use (PoU) Treatments for water purification can be the good solution which can solve the issue of unsafe potable water.
