Описание:
This important new study investigates the competing demand for water in the Bhavani and Noyyal River basins of south India from the early 19th century to the early 21st century from a historical perspective. In doing so, the book addresses several important questions:
* Did policy-makers visualise the future demand while diverting water from distant places or other basins? * Was efficient use ensured when the water was diverted or was it diverted in a manner that resulted in pollution and serious damage to the entire river basin? * Were natural flows taken care of in order to preserve the ecology and environment? * What were the factors that aggravated the competing demand for water and what were the consequences for the future? In the context of the current discourse on the competing demands for water, this book takes the debate forward, expanding the horizon of environmental history in the process. Until now, agriculture, industry and domestic water supply and their consequences for ecology, the environment and livelihoods have been given scant attention. Velayutham Saravanan's comprehensive account of both the colonial and post-colonial periods corrects this shortcoming in the field's literature and gives a holistic understanding of the problem and its full historical roots.
Thermoelectric materials permit the direct conversion of temperature differences into electric energy, and vice versa. They are therefore of highest technological interest in applications such as solid state coolers, waste heat recovery, sensors and detectors, and power generators including remote power generation. Thermoelectric materials are often called "environmentally green", and for good reasons. Not only can they help generate electrical energy from waste gases as they are generated in such processes as home heating, industrial fabrication and automotive motion. In cooling applications they eliminate the use of chemical refrigerant gases. Moreover, as thermoelectric conversion devices have no moving parts, they operate silently and have a very long life expectancy. The only current drawback of these devices is their poor efficiency. Scientists all over the world are therefore studying the structural, thermoelectric, charge-density and magnetic properties of the most promising types of these materials at the atomic and electronic level. In addition to providing an introduction to the field, the main objective of this book is to present the results of the growth and structural characterization of thermoelectric materials that are of high current interest; including Mg2Si, PbTe, Bi1-xSbx, Bi2Te3, Sb2Te3, Sn1-xGexTe and InSb.
