Available in PDF, EPUB and Kindle. Book excerpt: L'injection assistée par gaz est un procédé communément mis en œuvre pour économiser de la matière en créant une cavité dans une pièce plastique. Dans des cas d'applications plus complexes, il peut arriver que deux ou plusieurs bulles soient amenées à se rencontrer. Très longtemps cette connexion a été considérée comme impossible. Il se trouve que dans certaines configurations particulières ce phénomène peut être provoqué et est parfaitement reproductible. Cette connexion permet une homogénéisation du champ de pression supprimant ainsi les contraintes internes provoquées par le gradient de pression. Par ailleurs, il devient alors possible de maitriser le retrait de la matière en modifiant simplement la pression d'injection de gaz.

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
