Abstract:
The present investigation has addressed the eflects of PHC
contaminated culture medium on the morphology, physiology and
behaviour of shrimps] The shrimp Metapenaeus dobsoni is an important
member of the crustacean animal community abounding the oil
contaminated benthic regions of Cochin backwater system. Since it is
known that true pollutants can disrupt the sustainability of ecosystems by
its eflect on species, populations and communities, a representative
species was used for the study. The results discussed in this work is bound
to help in understanding the ecotoxicant resistance that the animal may
display under toxic conditions compared to aynamic steaay-state systems
in nature

Abstract:
The prime intension of the present work was a synthetic investigation of the
preparation, surface properties and catalytic activity of some transition metal
substituted copper chromite catalysts. Homogeneous co-precipitation method is
employed for the preparation of catalysts. Since the knowledge about the structure and
composition of the surface is critical in explaining the reactivity and selectivity of a
solid catalyst. a systematic investigation of the physico-chemical properties of the
prepared systems was carried out. The catalytic activity of these systems has also been
measured in several oxidation reactions of industrial as well as environmental
relevance. The thesis is dedicated to several aspects of chromite spinels giving
emphasis to its preparation, characterization and catalytic performance towards
oxidation reactions.
