The present study entails the effect of various factors affecting removal of copper from simulated wastewater by using rice husk ash as an adsorbent. Various standard solutions of copper nitrate were prepared and treated with rice husk ash (RHA) to investigate adsorption on the adsorbent under different conditions of pH, temperature, time and adsorbate dose. Maximum removal of Cu2+ was observed...
The main focus of the project was to dye the silk fabric using LawsoniaInermis dye (Henna). Dyeing of silk using henna would be possible using mordant. Potash Alum was chosen as the mordant because of its environment friendly nature. Four dyed samples were prepared as follows- sample dyed without mordant, sample dyed premordanted, sample dyed post mordanted, and simultaneous mordented. Better...
The study was carried out in selected districts of Gedeo zones of southern Nation nationality and people’s regional state: such as Wonago, Kochere and DillaZuria/chichu/ districts. The objective of the study was to asses production systems, opportunities and constraints of apiculture farming in Gedeo zones of SNNPRs. Beekeeping is a long-standing practice in the study districts and appears as...
Photosynthetic effects of the leaves extracts from Ipomoea cairica on Partheniumhysterophorus L were studied. Ipomoea cairica dried leaf powder (20g) was dissolved in distilled water (200ml) for foliar application. The seedlings were maintained under natural condition in Insect free net house. The experiment was carried out to analyze the effects of Ipomoea cairica leaves extract by measuring...
A quadrature rule for the numerical evaluation of integrals of analytic functions along directed line segments in the complex plane has been formulated using the transformed rule based on Gauss Legendre two point quadrature formulas and an interpolatory three point rule. The degree of precision has been increased from five to seven
