It is estimated that in India 75% of cancers of oral cavity are attributable to tobacco chewing, smoking and alcohol drinking. So the purpose of this book is to present the correlations of these premalignant disorders microscopically with in tobacco users and alcohol drinkers.
The content of this book is mainly research work, personally discovered for the first time in the whole history of the world, and is completely new. The use of sophisticated measurement systems based on scientific concepts and other such technologies has greatly improved understanding of the generation of speech and the treatment of puberphonia, giving rise to new scientific theories and concepts. Science ideas are subject to change. Ideas about voice boxes have changed, which led to the development of puberphonia voice correction.
Across the Pacific, populations of some species of sea turtles face extinction unless recent dramatic declines are reversed. The continuing decline of leatherbacks and loggerheads in particular illustrates the limitations of the current gradual and unilateral approach to conservation. Recovery requires instead a holistic solution that addresses all sources of mortality throughout the entire life history and habitat use of these transnational populations. Historically conservation efforts have focused on nesting sites to protect eggs and breeding females; mortality from coastal and highseas fisheries was not addressed. In the past five years, these recovery efforts have widened to include rig...
"The commercial landings of threatened and endangered species of marine turtles throughout U.S. waters have never been reported in detail. The early commercial sea turtle landings were sporadically collected and were published in a series of U.S. Government fisheries documents. Unfortunately, they have never been collated and summarized into a single data base or document. These are important base-line fisheries data on U.S. threatened and endangered species of sea turtles and provide considerable insight into the sociology and economics of the turtle fishery. Additionally, these data also provide basic biological information, such as species composition, seasonality, and sizes. These factors are necessary for understanding the ecology of these unique reptiles and enable resource managers to formulate sound management and conservation strategies, as mandated by the Endangered Species Act of 1973, and subsequent amendments. In this report, I summarize the commercial U.S. sea turtle landings as reported by the U.S. Fisheries Commission, Bureau of Commercial Fisheries and National Marine Fisheries Service for the continental U.S., Puerto Rico, and Hawaii"--Introduction
