among the environmental problems in nigeria is the lack of proper management of municipal solid wastes (msw), which is capable of releasing hazardous chemicals via leachate to the surrounding environment. in this study, the potential toxic effects of raw leachate obtained from aba-eku landfill (aerl) on clarias gariepinus; and the microorganisms that may be present in the leachate were investig...

Physico-chemical properties reflect the functional and structural characteristics of a protein. The comparative study of the physicochemical properties is important to know role of a protein in exploring its molecular evolution. A number of online and offline tools are available for calculating the physico-chemical properties of a single protein sequence. However, a tool is not available for a ...

The purpose of this paper is to list and discuss briefly some of the causes of chemical and physico-chemical disintegration of concrete and to point out some methods that can be used to study these causes. In this paper a distinction is made between physico-chemical (or chemico-physical) and mechanical causes of failure. Processes involving changes in chemical composition (chemical reactions pr...

The objective of this paper deal with the physico chemical aspects of certain colouring plants namely. Bixa orellana Linn. (Leaves) and Lawsonia inermis Linn (Leaves). The determined data under the physico chemical, chromatographic and spectrophotometric studies can be taken as a pharmacopoeial standards.

A new class of compounds, called as ionic liquids, has recently emerged as potential substitute for volatile organic solvents. Ionic liquids possess certain special physico-chemical characteristics that render them very useful in different areas of research and development. In this review, the physico-chemical properties and the applications of ionic liquids in chemical processes are critically...

Present work focused on the seasonal variations in the physico-chemical parameters of the freshwater temple pondPrayagtirth at Trimbakeshwar in Nashik district during summer, monsoon and winter. A total 15 parameters were analysed and their seasonal variation is discussed. The correlation matrix of the various physico-chemical parameters are computed and analysed.
