Ecology, Environmental Science & Conservation
Over the years, the scope of our scientific understanding and technical skills in ecology and environmental science have widened significantly, with increasingly greater emphasis on societal issues. In this book, an attempt has been made to give basic concepts of ecology, environmental science and various aspects of natural resource conservation. The topics covered primarily deal with environmental factors affecting organisms, adaptations, biogeography, ecology of species populations and species interactions, biotic communities and ecosystems, environmental pollution, stresses caused by toxics, global environmental change, exotic species invasion, conservation of biodiversity, ecological restoration, impact assessment, application of remote sensing and geographical information system for analysis and management of natural resources, and approaches of ecological economics. The main issues have been discussed within the framework of sustainability, considering humans as part of ecosystems, and recognising that sustainable development requires integration of ecology with social sciences for policy formulation and implementation.
Guru Gobind Singh (1666–1708)
The unifying theme in the life of Guru Gobind Singh was confrontation with the Mughals, which culminated in a struggle for political power. This fact is brought into sharp focus when we consider the Guru’s life and legacy simultaneously in the contexts of the Mughal Empire, its feudatory states in the hills, and the Sikh movement. The creation of the Khalsa in 1699 as a political community with the aspiration to rule made conciliation or compromise with the Mughal state almost impossible. Their long struggle ended eventually in the declaration of Khalsa Raj in 1765. Using contemporary and near contemporary sources in Gurmukhi, Persian, and English, J.S. Grewal presents a comprehensive study of this era of Sikh history. The volume elaborates on the life and legacy of Guru Gobind Singh and explores the ideological background of the institution of the Khalsa and its larger political context. Grewal, however, emphasizes that the legacy of the Khalsa was also social and cultural. This authoritative volume on the tenth Guru is a significant addition to the field of Sikh studies.

Quaternary Ammonium Salts
This text provides experimental methods for a wide range of organic reactions, systematically arranged according to reaction type, and describes the advantages and limitations of the procedures. Traditional methods to speed up organic reactions involve energy-consuming processes and costly and environmentally "unfriendly" solvents. Additionally, isolation of the product requires energy and time-consuming purification processes. A simple solution, especially for reactions involving anionic reactants, is the use of phase-transfer catalysis. Quaternary ammonium cations have the ability to transfer the anionic reactants as non-solvated ion-pairs from aqueous media into organic media. The resulta...
Biofungicides: Eco-Safety and Future Trends
The current volume focuses on novel sources of biofungicides, primarily providing complete knowledge of microbial and phytochemical fungicides, studying antifungal activity mechanisms as well as their role in disease management in plants, and fungicide bioremediation. The use of biofungicides as eco-friendly alternative to typical synthetic fungicides is projected to play a significant role in organic farming in the future. Key Features: Discovers novel sources of biofungicides Describes the role of biofungicides in the control of plant diseases Studies antifungal activity mechanisms Explores how to survey and select promising biofungicides
Microbial and Biotechnological Interventions in Bioremediation and Phytoremediation
The introduction of contaminants, due to rapid urbanisation and anthropogenic activities, into the environment causes unsteadiness, distress to the physico-chemical systems including living organisms, which possibly is threatening the dynamics of nature as well as the soil biology by producing certain xenobiotics. Hence, there is an immediate global demand for the diminution of such contaminants and xenobiotics which can otherwise adversely affect the living organisms. Some toxic xenobiotics include synthetic organochlorides such as polycyclic aromatic hydrocarbons (PAHs), and some fractions of crude oil and coal. The advancements in microbiology and biotechnology has lead to the launch of m...
