Complex oxides represent a class of materials with a plethora of fascinating properties like ferroelectricity, superconductivity, colossal magneto-resistance effect etc. The intriguing interplay of charge, spin and orbital ordering in these systems superimposed by the lattice effects opens a scientifically rewarding playground for both fundamental and application-oriented research. One such class of oxide materials is the perovskite manganites which exhibit large magneto-resistance effect commonly known as colossal magneto-resistance (CMR). In the present work we have studied the...

This Book markedly emphasizes the Importance of a person to know about his Genetics. Genetics Had already proven its importance in art of knowing about the species from the basic cell of reproduction and also about the various features that a species adopt from his ancestors. Thousands of inherited Human disorders have been catalogued till date, but the underlying genetic causes of less than 20 percent of those disorders have been discovered so far. Studies of population, families, and twins have provided good evidence that genetic factors play an important role in almost every aspect of...

A growing body of evidence suggests that air pollution from vehicles is an inescapable part of industrialised world. Though vast majority of research have focussed on effect of air pollutants on health of individuals, but studies regarding occupational exposure to petrochemical fumes are relatively few and those available, have yielded inconsistent results.So, in our research, we laid emphasis on changes in lung functions in petrol-pump workers chronically exposed to petrol/diesel fumes. Surprisingly, most workers remain asymptomatic till significant lung damage occurs.Even if observed values...
