This book covers innovative technologies and approaches for improvement of technical and economic parameters of functional geotechnical systems. The focus is on mathematical modelling of objects and processes, as well as the development of techniques and their control algorithms. The book comprises schemata of practical tasks solving related to mine ventilation and electrical circuit operation, cutter-loaders and mining electrical vehicles. It also demonstrates possible applications of hybrid technologies and IT-methods to the work of geotechnical systems. Implementation of methods and technologies presented in the book will allow to reduce energy resources consumption of geotechnical systems, and to enhance environmental and economic parameters of their operation, being one of the essential conditions for sustainable development in modern society.
The book is particular of interest to technical specialists, researchers, students and university teachers, whose work is connected to the improvement of efficiency of geotechnical systems.
Providing a proven set of energy efficiency measures and opportunities for saving energy and reducing operating costs for existing homes, this volume presents general tools and procedures for performing home weatherization such as insulation improvements as well as methods to reduce air leakage. The author describes several techniques and technologies that can reduce energy use or operating costs, including methods to retrofit existing homes to be net-zero energy buildings. Each chapter contains simplified calculation methods used to evaluate the effectiveness of various efficiency measures. The final chapter offers a series of case studies including examples of weatherized homes.

Описание: This unique volume is not just an in-depth analysis of Professor Swaminathan's brilliant contributions to basic cytogenetics, radiation biology, mutagenesis and genomic affinities of cultivated potato and its wild derivatives, but also the application of the new knowledge gained to improve the productivity of agricultural crops, as also to enhance their resistance to a variety of biotic and abiotic stresses. No other earlier biographies of Professor Swaminathan bring out these salient dimensions of his scientific achievements made at the Wageningen University, The Netherlands, Cambridge University, UK, and Wisconsin University, USA as well as Indian Agricultural Research Institute (IARI), New Delhi. This biography is also unique for its revelation that Professor Swaminathan's contributions par excellence have been in contemporary areas of crop improvement for productivity and resistance to pests and diseases.This volume is also unique in bringing out that Professor Swaminathan, Father of India's Green Revolution, wanted to use this chemically intensified system only to gain 'breathing space' and went on to propose a 'systems approach' -- based evergreen revolution in order to 'achieve productivity in perpetuity' through various pathways of ecoagriculture, and also integrated it with avenues for on-farm and non-farm livelihoods. Towards this goal, he made innovative uses of ecotechnologies in a 'biovillage' paradigm and modern information and communication technology (ICT) in Village Knowledge Centres (VKCs) to provide skill and knowledge empowerment respectively of the resource-poor rural women and men towards sustainable management of the natural resources for creating income-generating on-farm and non-farm livelihoods. This volume also brings out how Professor Swaminathan elegantly combined intellect and labour (hard work), and professional zeal with compassion for the poor. He is always open to new ideas, and new technologies without of course, compromising the values of traditional knowledge and ecological prudence of the rural and tribal people. This volume nicely captures how Professor Swaminathan with a deep and comprehensive understanding of the threats to the ecological foundations of agriculture and sustainable rural development, environmental degradation, social inequities and the climate change risks, has also harnessed science and technology to convert challenges into opportunities. This volume is written in a manner to serve also as a text book, going beyond the scope of just a biography. That should benefit generations of students on one hand, and sustain an interest in the book for many years on the other.
Автор: Thottathil Sapna E. Название: India`s Organic Farming Revolution: What It Means for Our Global Food System ISBN: 1609382773 ISBN-13(EAN): 9781609382773 Издательство: Mare Nostrum (Eurospan) Рейтинг: Цена: 21250.00 T Наличие на складе: Невозможна поставка. Описание: Should you buy organic food? Is it just a status symbol, or is it really better for us? Is it really better for the environment? What about organic produce grown thousands of miles from our kitchens, or on massive corporately owned farms? Is “local” or “small-scale” better, even if it’s not organic? A lot of consumers who would like to do the right thing for their health and the environment are asking such questions.Sapna Thottathil calls on us to rethink the politics of organic food by focusing on what it means for the people who grow and sell it—what it means for their health, the health of their environment, and also their economic and political well-being. Taking readers to the state of Kerala in southern India, she shows us a place where the so-called “Green Revolution” program of hybrid seeds, synthetic fertilizers, and rising pesticide use had failed to reduce hunger while it caused a cascade of economic, medical, and environmental problems. Farmers burdened with huge debts from buying the new seeds and chemicals were committing suicide in troubling numbers. Farm labourers suffered from pesticide poisoning and rising rates of birth defects. A sharp fall in biodiversity worried environmental activists, and everyone was anxious about declining yields of key export crops like black pepper and coffee.In their debates about how to solve these problems, farmers, environmentalists, and policymakers drew on Kerala’s history of and continuing commitment to grassroots democracy. In 2010, they took the unprecedented step of enacting a policy that requires all Kerala growers to farm organically by 2020. How this policy came to be and its immediate economic, political, and physical effects on the state’s residents offer lessons for everyone interested in agriculture, the environment, and what to eat for dinner. Kerala’s example shows that when done right, this kind of agriculture can be good for everyone in our global food system.
