Book Synopsis Caractérisation mécanique et modélisation du comportement jusqu'à rupture de membranes biologiques fibreuses by : Clémentine Jacquemoud
Download or read book Caractérisation mécanique et modélisation du comportement jusqu'à rupture de membranes biologiques fibreuses written by Clémentine Jacquemoud and published by . This book was released on 2007 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail représente la caractérisation et la modélisation mécanique complète d'une membrane biologique fibreuse : la peau humaine, lorsqu'elle est soumise à des sollicitations proches du choc conduisant à sa rupture. En effet, l'étude expérimentale a permis de mettre en relation des paramètres de la micro structure fibreuse avec les propriétés mécaniques du tissu, mesurées à l'échelle macroscopique. Cette évolution conjointe des propriétés à différentes échelles, a ensuite pu être retranscrite dans une loi de comportement à deux échelles. Son implantation dans un code éléments finis apporte ainsi une description locale du comportement du tissu. Les premières applications sur la peau humaine apportent, d'un point de vue expérimental, en plus des caractéristiques mécaniques classiques jusqu'à rupture, des données non conventionnelles et plus précises, d'une part sur le comportement de ce tissu (mesure du champ de déformation, quantification de son hétérogénéité) et d'autre part sur sa micro structure (orientation privilégiée des fibres, mécanisme de rupture). Les premières simulations sur la peau humaine mettent en évidence l'importance d'inclure, dans la loi de comportement, des paramètres propres aux fibres et à leur répartition dans le tissu, afin de modéliser des phénomènes observés expérimentalement (champ de déformation hétérogène, rupture progressive du tissu). Le protocole expérimental ainsi que le modèle de comportement ont été définis de telle sorte qu'ils puissent s'adapter aisément à tout type de membrane fibreuse, ce qui offre des perspectives intéressantes concernant les tissus sévèrement touchés lors d'accidents. De plus, compte tenu de la forte diversité inter individu, cette approche structurelle semble ouvrir la voie de la personnalisation des modèles, dans le sens où les paramètres structurels sont l'identité de chacun.

Download or read book Encapsulations written by Alexandru Grumezescu and published by Academic Press. This book was released on 2016-05-27 with total page 926 pages. Available in PDF, EPUB and Kindle. Book excerpt: Encapsulations, a volume in the Nanotechnology in the Agri-Food Industry series,presents key elements in establishing food quality through the improvement of food flavor and aroma. The major benefits of nanoencapsulation for food ingredients include improvement in bioavailability of flavor and aroma ingredients, improvement in solubility of poor water-soluble ingredients, higher ingredient retention during production process, higher activity levels of encapsulated ingredients, improved shelf life, and controlled release of flavor and aroma. This volume discusses main nanoencapsulation processes such as spray drying, melt injection, extrusion, coacervation, and emulsification. The materials used in nanoencapsulation include lipids, proteins, carbohydrates, cellulose, gums, and food grade polymers. Applications and benefits of nanoencapsulation such as controlled release, protections, and taste masking will be explained in detail. Includes the most up-to-date information on nanoencapsulation and nanocontainer-based delivery of antimicrobials Presents nanomaterials for innovation based on scientific advancements in the field Provides control release strategies to enhance bioactivity, including methods and techniques for research and innovation Provides useful tools to improve the delivery of bioactive molecules and living cells into foods

Download or read book Wood Adhesives written by Antonio Pizzi and published by CRC Press. This book was released on 2011-01-07 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood adhesives are of tremendous industrial importance, as more than two-thirds of wood products in the world today are completely or partially bonded together using a variety of adhesives. Adhesive bonding offers many advantages over other joining methods for wood components, and there has been a great deal of R& D activity in devising new wood adhesives or improving the existing ones. The modern mantra in all industrial sectors is: "think green, go green," which has attracted much attention in the wood adhesive industry. Therefore, there is also a lot of research activity in synthesizing environmentally benign and human-friendly wood adhesives. This book is divided into four parts: Part 1: Fundamental Adhesion Aspects in Wood Bonding; Part 2: Synthetic Adhesives; Part 3: Environment-friendly adhesives; and Part 4: Wood Welding and General Paper. It addresses many different types of wood adhesives, as well as bonding (welding) of wood components without adhesives, a more recent development. The information contained in this book is valuable for individuals engaged in all aspects of wood adhesion and adhesives and, hopefully, will inspire new ideas in wood adhesives, a topic of vital industrial importance.

Book Synopsis Diamond Based Composites by : Mark A. Prelas
Download or read book Diamond Based Composites written by Mark A. Prelas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diamond-based composites, with their advantages of hardness, high Young's modulus and the like, have demonstrated new and unusual features, such as stability to high temperatures and pressure shocks and a large internal surface that can be controlled to offer customised electrical, magnetic and optical properties, leading to efficient filters, absorbents, sensors and other tools for environmental control and monitoring. The current book covers the synthesis of materials, their characterization and properties, trends in high pressure and high temperature technologies, low pressure technologies, basic principles of DBC material science, and future developments in electronics, optics, industrial tools and components, biotechnology, and medicine. Wide band-gap materials are considered, ranging from molecular clusters, nanophase materials, growth, processing and synthesis. The processing of composite based materials can be classified into six basic methods: in situ growth, high pressure/high temperature catalytic conversion; mix and sinter (c-BN plus metal-ceramic polymer mix); direct sintering; direct polymorphic conversion; shock detonation; and SHS sintering.

Book excerpt: Azoles are a broad and promising class of five-membered heterocyclic compounds containing from one up to five nitrogen atom(s) that can also contain sulfur or oxygen atoms. Widely used as potent antifungal agents, various azole derivatives have also demonstrated many other promising biological properties. This book covers studies of several types of thiazole-based heterocyclic scaffolds, the development of 4-thiazolidinone and thiazole derivatives with heterocyclic fragments as potential candidates for new drugs against trypanosomiasis, numerous synthetic approaches for the synthesis of 1,2,3-triazoles, the application of N-azole, N,S-azole, and N,O-azole as well as their derivatives as retarders of metallic corrosion, and the integration of azoles in materials used for renewable energy processing and applications and wood treatment.
