Drug maltreatment in India is pretty much as old as somewhere else, if not more established, all along, weed drugs have been being used. Antiquated books are loaded with references to intoxicants, for example, 'soma rasa', 'dev goods', 'madira' and so on Opium became well known during the Mughal time frame. As of not long ago, cocaine had numerous lovers, particularly in 'red-light' regions. The post-war period saw the ascent of engineered drugs-the two energizers and depressants. Hard drugs like heroin and lysergic corrosive diethylamide (LSD) are being used. As of late found drugs like phencyclidine hydrochloride (Angel Dust) may likewise be known to specific clients in metropolitan region...
Analytical “chemists have not many instruments as strong as chromatography to quantify unmistakable analytes in complex examples. The force of chromatography comes from its capacity to isolate a combination of compounds, or "analytes", and decide their individual personality (substance construction) and focus. Chromatography can be isolated into three fundamental sorts that incorporate gas, liquid, and supercritical liquid chromatography. Liquid chromatography can additionally be partitioned into particle trade, divisions dependent on size, and surprisingly stretched out to gel based electrophoretic strategies. This book will give a fundamental prologue to various sorts of liquid and gas chromatography.
An advanced-level textbook of physical chemistry for the graduate (B.Sc) and postgraduate (M.Sc) students of Indian and foreign universities. This book is a part of four volume series, entitled "A Textbook of Physical Chemistry – Volume I, II, III, IV". CONTENTS: Chapter 1. Quantum Mechanics – I: Postulates of quantum mechanics; Derivation of Schrodinger wave equation; Max-Born interpretation of wave functions; The Heisenberg’s uncertainty principle; Quantum mechanical operators and their commutation relations; Hermitian operators (elementary ideas, quantum mechanical operator for linear momentum, angular momentum and energy as Hermition operator); The average value of the square of He...
The most comprehensive and best illustrated treatment of the fascinating tropical neem tree (Azadirachta indica) and its unique substances. The extracts from the neem tree have an enormously broad range of applications. The main substance azadirachtin, a tetranortriterpenoid, influences the hormone system of insects, exerting thereby a pesticidal effect. Feeding activity, reproduction and flying ability of insects are also affected. It is biologically degradable and can be easily extracted from the seeds of the tree. Other important uses of neem tree products are: - antifertility and population control - cure of human diseases - manure and nitrification inhibitors - feeds for domestic animals - soap production With its exhaustive treatment of the neem tree and closely related plants, this book provides us with an impressive example of the varied uses of renewable resources.
