Production of Biopesticide from Need Seed

Abstract Due to the toxic effects of chemical pesticide and other agro chemicals on human beings and livestock, residual toxicity, environmental problems, pest out-breaks and drastic effects on beneficial insects the use chemical pesticide and other agro chemicals are getting reduced /being banned globally. But Biopesticides that are extracted, for example, from neem seed can tackle these problems to make it more eco-friendly, economically viable and socially acceptable for the ...

THE USE OF SHEA BUTTER AS THE OIL BASE IN THE PREPARATION OF METHYL SALICYLATE (ANALGESIC) CREAMS

In the present study, an attempt was made to investigate the use of Shea butter as the oily base in the formulation of analgesic (Methyl salicylate) creams using hydrous wool fat base cream as standard. Methyl salicylate (The active ingredient), Bees wax, water and Shea butter obtained from local sources and refined were used separately on three different types on emulsifying agents namely cetrimide, polysorbate 80 and sodium lauryl sulphate, in the formulation of the analgesic cream. The st...

Influence of Composition on the Thermophysical Properties of LNG

The saturated liquid density deviations were compared using the PR, RSK (Advanced), AGA8, and GERG2008 EoSes. The bubble pressure deviations, saturated liquid densities, isobaric specific heat capacities, and enthalpy of vaporization were compared using the PR, RSK (Advanced) and GERG2008 EoSes. The GERG2008 EoS was used to analyse the effect of nitrogen and heavy alkanes on the thermophysical properties of LNG mixtures. Experimental density data was used to compare the accuracy of ...

CONSTRUCTION OF A STELL CUPBOARD

ABSTRACT The aim of this project was to construct a steel cupboard in order to help us acquire the knowledge of fabrication of a modern cupboard and the essence of it. Also to enable us (the students of chemical Engineering) to know how to construct as future engineers. The construction of steel cupboard was done using a square pipe of 1.5mm thickness and the mild steel having a thickness of 1.5mm. it was mark out cut, welded, filled and painted. The  cupboard has length and height of ...
