ABSTRACT The quality of pipe borne water supplied by Imo State Water Corporation has been assessed by analyzing samples of water collected from different locations for their physicochemical parameters and bacteriological quality. The observed values were compared with standard values given by the World Health Organization for potable water .The quality of the analyzed water is found fit for human consumption.

CORE PRACTICAL ONE Describe how the effect of caffeine on heart rate in Daphnia can be investigated practically‚ and discuss whether there are ethical issues in the use of invertebrates. Daphnia‚ the water flea‚ is a small freshwater crustacean which lacks physiological methods of maintaining a constant body temperature. This means that if the environmental temperature changes‚ its body temperature does so too and its metabolic rate will be expected to rise or fall accordingly. So the temperature

Hydrogel based controlled release formulations: Designing considerations‚ characterization techniques and applications. Abstract Hydrogels have evolved over the last decade as materials of choice in varied biomedical applications. This is associated with the inherent biocompatible nature of the hydrogels. The modulation of the properties of the hydrogels is easily possible due to the availability of polymers of varied chemistry and physical properties. This review discusses the pharmaceutical

INTRODUCTION Isolation of Aspergillus niger from garden soil for the production of amylase enzyme and effect of various parameters on enzyme‚ production is the main aim of this study. Enzymes are protein catalysts synthesized by living systems and are important in synthetic as well as degradative process. Amylases are starch degradative enzymes that catalyze the hydrolysis of internal a-1‚ 4-0-glycosidic bonds in polysaccharides such as starch in to simple sugar (glucose and maltose). It is produced
