Tecnología energética y medio ambiente I


Book Description

El objetivo general de esta publicación es ofrecer una visión amplia de las fuentes, las transformaciones y las aplicaciones tecnológicas de la energía. En cuanto al medio ambiente, se centra en el conocimiento de los aspectos normativos y de legislación estatal y europea, sin entrar a analizar en detalle los aspectos relacionados con la preservación, la contaminación en sus diversos aspectos y la eliminación de fuentes de riesgos. En cuanto a la tecnología energética, pretende dar a conocer las diferentes fuentes de energía, los combustibles, la combustión como fuente de obtención de energía térmica y su utilización para la obtención de energía mecánica y eléctrica mediante las máquinas térmicas directas (motores de combustión interna, turbinas de gas y turbinas de vapor), las máquinas inversas o de refrigeración, así como la obtención conjunta de calor y electricidad mediante la utilización de la cogeneración. Asimismo, se introducen las energías alternativas y, entre ellas, la energía solar. Para el seguimiento correcto de esta publicación se requieren conocimientos de termodinámica en sus aspectos básicos y de aplicación. Ello implica conocer los principios de la termodinámica y de las magnitudes utilizadas (entalpía, energía interna, entropía,...) y el planteamiento de balances de energía, entropía y exergía en todo tipo de dispositivos. Asimismo, es conveniente conocer los diagramas termodinámicos y las tablas de propiedades termodinámicas, y su manejo.







Culture and Environment


Book Description

The inspiration for this book arose out of a large international conference: the ninth World Environmental Education Congress (WEEC) organized under the theme of Culture/Environment. Similarly, the theme for this book focuses on the Culture/Environment nexus. The book is divided into two parts: Part 1 consists of a series of research studies from an eclectic selection of researchers from all corners of the globe. Part 2 consists of a series of case studies of practice selected from a wide diversity of K-Postsecondary educators. The intent behind these selections is to augment and highlight the diversity of both cultural method and cultural voice in our descriptions of environmental education practice. The chapters focus on a multi-disciplinary view of Environmental Education with a developing view that Culture and Environment may be inseparable and arise from and within each other. Cultural change is also a necessary condition, and a requirement, to rebuild and reinvent our relationship with nature and to live more sustainably. The chapters address the spirit of supporting our praxis, and are therefore directed towards both an educator and researcher audience. Each chapter describes original research or curriculum development work.

APPLIED BOTANY


Book Description

With new discoveries and inventions in science, application of botany has attained many dimensions. Besides the conventional application of botanical sciences, forensic botany; nanobotany; phytoremideation and phytominimg; environmental impact assessment, seed quality enhancement through priming are the new dimensions of applied botany. The industrial applications of botany are in paper pulp, rubber, dye and gum industries. At social front, besides providing the livelihood and employment through cultivation of crops, the branches of botany like community forestry are playing major role in the upliftment of folks. Use of mechanisms of carnivorous plants in plant protection; and management of invasive plants for economic gains and conservation of biodiversity are new challenges in applied botany.

Biology, Productivity and Bioenergy of Timber-Yielding Plants


Book Description

Face to the current global energy crisis, there is an urgent necessity of searching for alternatives to fossil fuels, and this book shows how timber is a promising resource for sustainable energy production. Northeast Mexico represents an important forest resource to satisfy the needs of the population in these areas. In order to harness these forest resources, technology for exploring these valuable resources must be developed. These technologies (with special reference to biology and wood technologies) are available in scattered form in a few books but there is no central, comprehensive source for practical forest scientists for adopting efficient forest management, practice, and exploration. This book deals with the characterization of the vegetation, morphology, phenological development, biomass production (leaf, litter, wood), and bioenergy of some timber-yielding species of Northeast Mexico, which will serve as a guide to study timber-yielding plants in the native vegetation of Tamaulipan thornscrub and experimental plantations. This includes morphology, vegetation cover, biomass production in terms of volume leaf biomass, litter, and volume of fire wood and timber. Special emphasis is given to the estimation of bioenergy products and chemical composition (Ph, extractable lignin, and inorganic elements). Large variations exist in vegetation cover, morphology, phenological development, biomass production of leaf and litter, volume of wood and various variable of bioenergy products among the selected species. The maximum production was found in summer and the volume of the harvestable timber was obtained in experimental plantations. This book, therefore, will serve as a practical handbook to characterize timber-yielding plants, which will help to efficiently manage forestry resources.
