Book excerpt: Le travail qui est présenté dans cette thèse soulève la difficulté de sécher des produits thermoïoniques avec les procédés de déshydratation traditionnels. Ces procédés sont ici représentés par le séchage à l'air chaud, le séchage sous vide et la lyophilisation. Deux nouveaux procédés, inventés et mis au point au laboratoire Maitrise des technologies agro-industrielles, présentent une alternative aux procédés traditionnels. Ces deux nouveaux procédés, la détente instantanée contrôlée (DIC) et la déshydratation par détentes successives (DDS), sont basés sur une détente instantanée vers le vide qui provoque l'auto-vaporisation d'une partie de l'eau. La DIC utilise la vapeur pour monter en pression avant la détente. L’auto-vaporisation donne alors une structure poreuse au produit. Ce procédé s'insère dans un séchage par air chaud traditionnel ou peut être précédé d'un pressage. La DDS utilise de l'air comprimé et l'auto-vaporisation est moins intense que dans le cas de la DIC. La répétition des cycles DDS de montée en pression et détente permet la déshydratation complète le produit. L’étude consiste à comparer les procédés sur leur cinétique de séchage et sur la qualité du produit fini. Le poisson a été choisi comme produit de référence pour sa sensibilité au séchage et à la chaleur et pour les propriétés rhéologiques de sa chair. En premier lieu, les cinétiques de déshydratation des cinq procédés sont décrits et une méthode de caractérisation de la vitesse de séchage est définie. Dans le cas des nouveaux procédés DIC et DDS, l'effet des paramètres opératoires est étudié et souvent optimisé par plans d'expériences. Les nouveaux procédés montrent une grande rapidité pour le séchage du poisson. En effet, alors que le séchage convectif demande une trentaine d'heures pour déshydrater des cubes de poisson (et 17 h pour le séchage sous vide), la DDS ne prend que 7 h et le procédé pressage-DIC-air chaud environ 3,5 h. En outre, la DIC élimine les problèmes de transferts de matière liés à la croûte qui se forme lors des séchages par air chaud, sous vide et dans une moindre mesure, par DDS. Les différents procédés sont ensuite comparés sur le plan de la qualité finale des produits. Les mesures réalisées sur les produits DIC montrent leur grande qualité sur le plan fonctionnel : masse volumique importante, peu de micro-organismes et une très bonne réhydratation. Ces propriétés sont même supérieures à celles des produits lyophilisés. En revanche, la DDS se montre de qualité moyenne, proche de la qualité du séchage sous vide. Le séchage à l'air chaud présente d'importants défauts pour chacune des trois caractéristiques évaluées. Les produits sont également comparés sur le plan de la qualité organoleptique. Les profils sensoriels de couleur et de texture, confortés par des mesures instrumentales, montrent encore une fois que les poissons DIC, bien que moins appréciés par le consommateur, sont très proches des produits lyophilisés. Les produits DDS et séchés sous vide présentent encore une couleur et une texture moyenne mais qui restent supérieures à celles des produits séchés par air chaud. Enfin, les observations structurales et le recoupement de données permettent l'émission de certaines hypothèses sur le déroulement des phénomènes apparaissant au cours de la détente instantanée et en particulier au cours de la DIC. L'importance de l'hydrothermorhéologie du produit est mise en avant dans les phénomènes d'expansion. De la même manière l'observation microscopique de produits alimentaires expansés montre que les bulles et cavités apparaissent principalement au niveau cellulaire. La microrhéologie des constituants de l'aliment est donc également un des principaux facteurs de l'expansion.

Book excerpt: SCIENCE AND EMPIRES: FROM THE INTERNATIONAL COLLOQUIUM TO THE BOOK Patrick PETITJEAN, Catherine JAMI and Anne Marie MOULIN The International Colloquium "Science and Empires - Historical Studies about Scientific De velopment and European Expansion" is the product of an International Colloquium, "Sciences and Empires - A Comparative History of Scien tific Exchanges: European Expansion and Scientific Development in Asian, African, American and Oceanian Countries". Organized by the REHSEIS group (Research on Epistemology and History of Exact Sciences and Scientific Institutions) of CNRS (National Center for Scientific Research), the colloquium was held from 3 to 6 April 1990 in the UNESCO building in Paris. This colloquium was an idea of Professor Roshdi Rashed who initiated this field of studies in France some years ago, and proposed "Sciences and Empires" as one of the main research programmes for the The project to organize such a colloquium was a bit REHSEIS group. of a gamble. Its subject, reflected in the title "Sciences and Empires", is not a currently-accepted sub-discipline of the history of science; rather, it refers to a set of questions which found autonomy only recently. The terminology was strongly debated by the participants and, as is frequently suggested in this book, awaits fuller clarification.

Download or read book Performance of Cement Based Materials in Aggressive Aqueous Environments written by Mark Alexander and published by Springer Science & Business Media. This book was released on 2012-12-18 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete and cement-based materials must operate in increasingly aggressive aqueous environments, which may be either natural or industrial. These materials may suffer degradation in which ion addition and/or ion exchange reactions occur, leading to a breakdown of the matrix microstructure and consequent weakening. Sometimes this degradation can be extremely rapid and serious such as in acidic environments, while in other cases degradation occurs over long periods. Consequences of material failure are usually severe – adversely affecting the health and well-being of human communities and disturbing ecological balances. There are also large direct costs of maintaining and replacing deteriorated infrastructure and indirect costs from loss of production during maintenance work, which place a great burden on society. The focus of this book is on addressing issues concerning performance of cement-based materials in aggressive aqueous environments , by way of this State-of-the-Art Report. The book represents the work of many well-known and respected authors who contributed chapters or parts of chapters. Four main themes were addressed: I. Nature and kinetics of degradation and deterioration mechanisms of cement-based materials in aggressive aqueous environments, II. Modelling of deterioration in such environments, III. Test methods to assess performance of cement-based materials in such environments, and which can be used to characterise and rate relative performance and inform long term predictions, IV. Engineering implications and consequences of deterioration in aggressive aqueous environments, and engineering approaches to the problem.

Available in PDF, EPUB and Kindle. Book excerpt: The Sounds of Early Cinema is devoted exclusively to a little-known, yet absolutely crucial phenomenon: the ubiquitous presence of sound in early cinema. "Silent cinema" may rarely have been silent, but the sheer diversity of sound(s) and sound/image relations characterizing the first 20 years of moving picture exhibition can still astonish us. Whether instrumental, vocal, or mechanical, sound ranged from the improvised to the pre-arranged (as in scripts, scores, and cue sheets). The practice of mixing sounds with images differed widely, depending on the venue (the nickelodeon in Chicago versus the summer Chautauqua in rural Iowa, the music hall in London or Paris versus the newest palace cinema in New York City) as well as on the historical moment (a single venue might change radically, and many times, from 1906 to 1910). Contributors include Richard Abel, Rick Altman, Edouard Arnoldy, Mats Björkin, Stephen Bottomore, Marta Braun, Jean Châteauvert, Ian Christie, Richard Crangle, Helen Day-Mayer, John Fullerton, Jane Gaines, André Gaudreault, Tom Gunning, François Jost, Charlie Keil, Jeff Klenotic, Germain Lacasse, Neil Lerner, Patrick Loughney, David Mayer, Domi-nique Nasta, Bernard Perron, Jacques Polet, Lauren Rabinovitz, Isabelle Raynauld, Herbert Reynolds, Gregory A.

This book was released on 2019-03-12 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: The State of the World's Biodiversity for Food and Agriculture presents the first global assessment of biodiversity for food and agriculture worldwide. Biodiversity for food and agriculture is the diversity of plants, animals and micro-organisms at genetic, species and ecosystem levels, present in and around crop, livestock, forest and aquatic production systems. It is essential to the structure, functions and processes of these systems, to livelihoods and food security, and to the supply of a wide range of ecosystem services. It has been managed or influenced by farmers, livestock keepers, forest dwellers, fish farmers and fisherfolk for hundreds of generations. Prepared through a participatory, country-driven process, the report draws on information from 91 country reports to provide a description of the roles and importance of biodiversity for food and agriculture, the drivers of change affecting it and its current status and trends. It describes the state of efforts to promote the sustainable use and conservation of biodiversity for food and agriculture, including through the development of supporting policies, legal frameworks, institutions and capacities. It concludes with a discussion of needs and challenges in the future management of biodiversity for food and agriculture. The report complements other global assessments prepared under the auspices of the Commission on Genetic Resources for Food and Agriculture, which have focused on the state of genetic resources within particular sectors of food and agriculture.

Download or read book Traditional Forest Related Knowledge written by John A. Parrotta and published by Springer Science & Business Media. This book was released on 2011-10-14 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring a topic of vital and ongoing importance, Traditional Forest Knowledge examines the history, current status and trends in the development and application of traditional forest knowledge by local and indigenous communities worldwide. It considers the interplay between traditional beliefs and practices and formal forest science and interrogates the often uneasy relationship between these different knowledge systems. The contents also highlight efforts to conserve and promote traditional forest management practices that balance the environmental, economic and social objectives of forest management. It places these efforts in the context of recent trends towards the devolution of forest management authority in many parts of the world. The book includes regional chapters covering North America, South America, Africa, Europe, Asia and the Australia-Pacific region. As well as relating the general factors mentioned above to these specific areas, these chapters cover issues of special regional significance, such as the importance of traditional knowledge and practices for food security, economic development and cultural identity. Other chapters examine topics ranging from key policy issues to the significant programs of regional and international organisations, and from research ethics and best practices for scientific study of traditional knowledge to the adaptation of traditional forest knowledge to climate change and globalisation.
