This book was released on 2015 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: De nos jours, la connaissance des propriétés d'écoulement d'un mélange de poudre devient indispensable pour mettre au point un procédé de fabrication approprié ou lors du développement d'un nouveau produit. En effet, elles conditionnent le temps de remplissage de la matrice, la cadence et garantit l'uniformité de masse lors des répartitions volumétriques. Par conséquent, il y a donc un besoin de caractérisation très complète des propriétés rhéologiques des solides divisés, représentés par les poudres et milieux granulaires, pour maitriser les procédés industriels les mettant en œuvre. Plusieurs facteurs interviennent dans la fluidité d'un grain que ce soit sa morphologie, sa densité, sa porosité, son humidité, son électricité statique ou encore sa granulométrie. Cette étude décrit les propriétés rhéologiques des mélanges de poudres et propose de voir l'impact de l'ensemble de ses facteurs en fabrication industrielle.Les différentes méthodes de caractérisation rhéologique d'un mélange de poudre y sont présentées et pour illustrer cette étude, un travail de caractérisation des propriétés physiques et d'aptitude à l'écoulement de plusieurs références produites par les Laboratoires Juva Productions a été effectué. Cette analyse prenant en compte les différentes caractéristiques des machines utilisées en production : machines à comprimés ronds (11 mm), oblong, 22 mm et géluleuse; a pour objectif d'établir les caractéristiques rhéologiques optimales des poudres pour chaque ligne de production étudiées.

Book Synopsis Sustainable Protein Production and Consumption: Pigs or Peas? by : Harry Aiking
Download or read book Sustainable Protein Production and Consumption: Pigs or Peas? written by Harry Aiking and published by Springer Science & Business Media. This book was released on 2006-02-23 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable Protein Production and Consumption: Pigs or Peas? is a book that presents and explores the PROFETAS programme for development of a more sustainable food system by studying the feasibility of substituting meat with plant based alternatives. The emphasis is on improving the food system by reducing the use of energy, land, and freshwater, at the same time limiting the impacts on health and animal welfare associated with intensive livestock production. It is clear that such a new perspective calls not only for advanced environmental and technological research, but also for in-depth societal research, as the acceptance of new food systems is critically contingent on perceptions and attitudes of modern consumers. In this unique multidisciplinary setting, PROFETAS has opened up pathways for a major transition in protein food production and consumption, not by just analyzing the food chain, but rather by exploring the entire agricultural system, including biomass for energy production and the use of increasingly scarce freshwater resources. The study presented here is intended to benefit every stakeholder in the food chain from policymakers to consumers, and it offers guiding principles for a transition towards an ecologically and socially sustainable food system from a multi-level perspective.
Book Synopsis Adhesion between polymers and concrete / Adhésion entre polymères et béton by : H. R. Sasse
Download or read book Adhesion between polymers and concrete / Adhésion entre polymères et béton written by H. R. Sasse and published by Springer. This book was released on 2013-11-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

This book was released on 2018-08-29 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital fabrication has been termed the “third industrial revolution”, and is promising to revolutionize many disciplines, including most recently the construction sector. Both academia and industry see immense promise in cementitious materials, which lend themselves well to additive manufacturing techniques for digital fabrication in construction. With this recent trend and high interest in this new research field, the 1st RILEM International Conference on Concrete and Digital Fabrication (Digital Concrete 2018) was organized. Since 2014, ETH Zurich has been host for the Swiss National Centre for Competence in Research (NCCR) for Digital Fabrication in Architecture, which is highly interdisciplinary and unique worldwide. In 2018, this NCCR opened the “DFAB House”, which incorporates many digital fabrication principles for architecture. It is also responsible for the 600 m2 Robotic Fabrication Lab and the first robotically built roof in the world. Held in tandem with Rob|Arch 2018, the leading conference for robotics in architecture, RILEM deemed it the right time to combine forces at this new conference, which will be the first large conference to feature the work of the recently created RILEM Technical Committee on Digital Fabrication with Cement-based Materials, among other leaders in this new field worldwide. This conference proceedings brings together papers that take into account the findings in this new area. Papers reflect the varying themes of the conference, including Materials, Processing, Structure, and Applications.

Book Synopsis Food Biochemistry and Food Processing by : Y. H. Hui
Download or read book Food Biochemistry and Food Processing written by Y. H. Hui and published by John Wiley & Sons. This book was released on 2008-02-15 with total page 786 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biochemistry of food is the foundation on which the research and development advances in food biotechnology are built. In Food Biochemistry and Food Processing, lead editor Y.H. Hui has assembled over fifty acclaimed academicians and industry professionals to create this indispensable reference and text on food biochemistry and the ever-increasing development in the biotechnology of food processing. While biochemistry may be covered in a chapter or two in standard reference books on the chemistry, enzymes, or fermentation of food, and may be addressed in greater depth by commodity-specific texts (e.g., the biotechnology of meat, seafood, or cereal), books on the general coverage of food biochemistry are not so common. Food Biochemistry and Food Processing effectively fills this void. Beginning with sections on the essential principles of food biochemistry, enzymology and food processing, the book then takes the reader on commodity-by-commodity discussions of biochemistry of raw materials and product processing. Later sections address the biochemistry and processing aspects of food fermentation, microbiology, and food safety. As an invaluable reference tool or as a state-of-the-industry text, Food Biochemistry and Food Processing fully develops and explains the biochemical aspects of food processing for scientist and student alike.

Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.
Book Synopsis Faecal Sludge Management by : Linda Strande
Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
