The Fifth International Meeting on Cholinesterases convened in Madras, India, in September of 1994. The long and rich history and culture of India provided an excellent setting for the meeting. More than 120 delegates from Asia, Australia, Europe and North America heard 54 oral presentations and viewed 54 posters on current research on enzymes of the cholinesterase family. The aim of this book is to compile the presentations of the Fifth International Meeting on Cholinesterases into a volume that describes recent investigations on the structure and catalytic function of acetylcholinesterase (AChE), butyrylcholinesterase (BuChE) and related enzymes, as well as studies on the molecular and cellular biology of these enzymes and the genes which encode them. Cholinesterases enjoy a long and storied history in diverse areas. In basic biochemical research, AChE is one of the best studied, though yet enigmatic, of enzymes. The efficient catalytic function of this enzyme presents the biochemist with a fundamental challenge in understanding the relationship between structure and function. AChE and BuChE belong to a family of proteins, the alB hydrolase fold family, whose constituents evolutionarily diverged from a common ancestor. Proteins in this family have a wide range of physiological functions. In commerce, AChE is a prime target for agricultural insect control, and for the development of therapeutic agents for Alzheimer's disease.

This book was framed to reduce the accumulation of CO2 concentration in the earth by means of different Carbon Capture and Storage technologies (CCS). CCS involves the capturing of CO2 from large point sources to a storage site. The major and prominently used technologies for CCS systems are Geological Storage, Ocean Storage, Mineral Carbonation and Industrial Use of CO2. Basically ocean takes up atmospheric CO2 on an enormous scale approximately 7 billion metric tons of CO2 per year absorbing it at the surface and transferring it to the deep waters, out of contact with the atmosphere for centuries. So, compared to the carbon reservoirs on land and in the atmosphere, the oceans have an enormous and under-utilised potential to sequester anthropogenic CO2 by possible methodologies likes Geological Formations under the Seabed, On the Seafloor and Water Column of the Deep Ocean. Before going for ocean storage technology the steps to be taken for consideration is biological consequences, government interventions, public acceptance and climate change.

Groundwater studies touch all realms of the hydrologic cycle.Sustainable management of this precious natural resource is possible only when there is a complete understanding of all the processes responsible for its storage in different aquifers as well as its movement from place to place.So it will require the knowledge about soils, geology, and structural features associated with the groundwater reservoirs.This book is the result of such an integrated study of groundwater in a tropical river basin in South India. The water level variations and groundwater chemistry is explained here in some detail for identifying the discharge and recharge ares in the basin and also to find the suitability of water for various uses.The geologic controls of water chemistry and its spatial variation throughout the basin is also illustrated with the help of statistical as well as GIS tools.A separate chapter on modeling is a highlight of this work.This will definitely benefit hydrogeologists, postgraduates and researchers in geology, geography students interested in morphometric analysis of river basins and also professionals in various fields of geoinformatics.

MLIR systems can facilitate the researchers and the end users to discover appropriate information in the preferred language. Due to the versatile applicability of MLIR systems, these systems require careful and thorough evaluations to demonstrate their desired performance. Therefore, the work reported in this book describes the greater efforts that are taken to develop a set of Metrics under Binary Retrieval and Ranked Relevance scheme for Evaluating the Performance of MLIR Systems. An Empirical and Statistical analysis is done to validate the proposed metrics under specified scheme of IR systems.

The aim of this book is to develop a Multi-Level security model for web service computing environments. This book describes about an Hardware Level Authentication scheme of web service consumers for secure communication with the service providers and History based Accounting and Reacting Denial of Service attack (DoS) model to detect and prevent possible DoS attacks in web service computing. The main objectives of this book are to provide built in authentication for web service consumers. It also minimizes the security constraints and challenges in any close group web service communication. This book has engaged the E-learning framework as a test bed to carry out the experiments in support of the proposed idea and its goals. The E-learning framework provides all the possible aspects of web service computing to perform the experimentation of this book. The experimental results in this book reveal the performance and accuracy of the Two Tier Security Framework for SOS.
