This book was released on 2016-11-04 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parmi les multitudes d'huiles vegetales utilisees comme carburant, l'huile d'arachide n'est pas en reste dans le cadre des etudes sur les interactions mecaniques et fluidiques a l'interieur des moteurs diesels. Les resultats d'experience sur le moteur DEUTZ F2L912W expriment que cette huile a des qualites carburant acceptables malgre ses actions assez agressives sur la viscosite de l'huile lubrifiante et sur l'etat de surface de la chemise du moteur. Du point de vue financier, l'huile d'arachide est plus couteuse que le gazole mais en termes d'emission, elle est moins polluante que les hydrocarbures conventionnels. C'est l'occasion de dire que les biocarburants se voient les premiers concurrents des carburants fossiles d'ici quelques temps.

Download or read book Perspectives for Agroecosystem Management written by Peter Schroder and published by Elsevier. This book was released on 2011-08-19 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable agriculture is a key concept for scientists, researchers, and agricultural engineers alike. This book focuses on the FAM- project (FAM Munich Research Network on Agroecosystems) of the 1990s as a means to assessing, forecasting, and evaluating changes in the agroecosystems that are necessary for agricultural sustainability. The management of two separate management systems: an organic and an integrated farming system are described to provide an interdisciplinary approach Changes of matter fluxes in soils, changes of trace gas fluxes from soils, precision farming in a small scale heterogen landscape, influence of management changes on flora and fauna, as well as the development of agroecosystem models, the assessment of soil variability and the changes in nutrient status are important aspects of this book.* Contains detailed results and insight of a long-time project on agricultural sustainability* Provides an interdisciplinary approach for comprehensive understanding by scientists and researchers of soil, plants, agriculture, and environment * Includes an international perspective
