Available in PDF, EPUB and Kindle. Book excerpt: Bien que les matériaux composites renforcés par fibres végétales (PFCs) représentent une solution attractive pour la conception de structures légères, performantes et à faible coût environnemental, leur développement nécessite des études approfondies concernant les mécanismes à la base du comportement non-linéaire en traction exprimé, ainsi que de la variabilité des propriétés mécaniques. Compte tenu de leur caractère multi-échelle, ces travaux de thèse visent à contribuer, via une approche numérique, à l'étude de la propagation de comportement à travers les échelles des PFCs. Dans un premier temps, l'étude se focalise sur l'échelle fibre : un modèle 3D de comportement de la paroi est d'abord implémenté dans un calcul EF, afin d'établir l'influence de la morphologie de la fibre sur le comportement exprimé. Une fois l'impact non négligeable de la morphologie déterminé, une étude des liens entre morphologie, matériau et ultrastructure et comportement en traction est menée via une analyse de sensibilité dans le cas du lin et du chanvre. La deuxième partie du travail es dédiée à l'échelle du pli de composite. Une nouvelle approche multi-échelle stochastique est développée et implémentée. Elle est basée sur la définition d'un volume élémentaire (VE) à microstructure aléatoire pour décrire le comportement du pli. L'approche est ensuite utilisée pour étudier la sensibilité du comportement du VE aux paramètres nano, micro et mésoscopiques. L'analyse de sensibilité, menée via le développement de la réponse sur la base du chaos polynomial, nous permet ainsi de construire un métamodèle du comportement du pli.

Available in PDF, EPUB and Kindle. Book excerpt: Using plant material as raw materials for construction is a relatively recent and original topic of research. This book presents an overview of the current knowledge on the material properties and environmental impact of construction materials made from plant particles, which are renewable, recyclable and easily available. It focuses on particles and as well on fibers issued from hemp plant, as well as discussing hemp concretes. The book begins by setting the environmental, economic and social context of agro-concretes, before discussing the nature of plant-based aggregates and binders. The formulation, implementation and mechanical behavior of such building materials are the subject of the following chapters. The focus is then put upon the hygrothermal behavior and acoustical properties of hempcrete, followed by the use of plant-based concretes in structures. The book concludes with the study of life-cycle analysis (LCA) of the environmental characteristics of a banked hempcrete wall on a wooden skeleton. Contents 1.

This book was released on 2009-10-19 with total page 689 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fibres usually experience tensile loads whether they are used for apparel or technical structures. Their form, which is long and fine, makes them some of the strongest materials available as well as very flexible. This book provides a concise and authoritative overview of tensile behaviour of a wide range of both natural and synthetic fibres used both in textiles and high performance materials. After preliminary chapters that introduce the reader to tensile properties, failure and testing of fibres, the book is split into two parts. Part one examines tensile properties and failure of natural fibres, such as cotton, hemp, wool and silk. Part two discusses the tensile properties and failure of synthetic fibres ranging from polyamide, polyester and polyethylene fibres to carbon fibres. Many chapters also provide a general background to the fibre, including the manufacture, microstructure, factors that affect tensile properties as well as methods to improve tensile failure. With its distinguished editor and array of international contributors, Handbook of tensile properties of textile and technical fibres is an important reference for fibre scientists, textile technologists and engineers, as well as those in academia. Provides an overview of tensile behaviour of a wide range of both natural and synthetic fibres Examines tensile characterisitics, tensile failure of textiles fibres and factors that affect tensile properties Discusses mircostructures and each type of fibre from manufacture to finished product

Available in PDF, EPUB and Kindle. Book excerpt: This important and insightful book provides, for the first time, a broad presentation of ongoing research into public participation in landscape conservation, management and planning, following the 2000 European Landscape Convention which came into force in 2004. The book examines both the theory of participation and what lessons can be learnt from specific European examples. It explores in what manner and to what extent the provisions for participation in the European Landscape Convention have been followed up and implemented. It also presents and compares different experiences of participation in selected countries from northern, southern, eastern and western Europe, and provides a critical examination of public participation in practice. However, while the book’s focus is necessarily on Europe, many of the conclusions drawn are of global relevance. The book provides a valuable reference for researchers and advanced students in landscape policies and management, as well as for professionals and others interested in land-use planning and environmental management.

Solid state fermentation, popularly abbreviated as SSF, is currently investigated by many groups throughout the world. The study of this technique was largely neglected in the past in European and Western countries and there is now a high demand for SSF, meaning in food, environment, agricultural, phannaceutical and many other biotechnological applications. It gives me satisfaction to note that the importance of this technique was realised at my department way back in 1975 since then, our team has put concentrated efforts on developing this technique. xvii Foreword Advances in Solid State Fermentation Foreword M. PUYGRENIER Agropolis Valorisation, Avenue d' Agropolis, 34394 Montpellier Cedex 5, France. On the name of the Scientific Community, I would like to express the wish that this International Symposium on SSF should be successful. Solid State Fermentation is part of biotechnology research. It consists on seeding solid culture medium with bacteria or fungi (filamentous or higher) and on producing, in this medium (solid components and exudates) metabolites and high value products. In fact, this process is very old. In older industries such the food and agricultural, this technique has been extensively used. An example of this is the production of pork sausages and Roquefort cheese. Pharmaceutical industry could make extensive use of SSF in the production of secondary metabolites of many kinds and development in this direction is soon expected.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The volume draws from René Devisch’s encounters with groups in southsaharan Africa, primarily. The author had the privilege to immerse himself, around the clock, in the Yakaphones’ activities and thoughts in southwest DR Congo from 1972 to 1974, and intermittently in Kinshasa’s shanty towns, from 1986 to 2003. The author first examines what sparked his choice to come to Congo, and then to pursue research among the Yakaphones in the borderland with Angola. He then invites us to follow the trajectory of his plural anthropological view on today’s multicentric world. It leads us to his praise for honorary doctor Jean-Marc Ela’s work. He then examines the proletarian outbursts of violence that rocked Congo’s major cities in 1991 and 1993. These can be read as a settling of scores with the disillusioning colonial and missionary modernisation, along with president Mobutu’s millenarian Popular Movement of the Revolution. Furthermore, after considering the morose reduction of a major Yaka dancing mask into a mere museum-bound curio in Antwerp, the book unravels the Yakaphones’ perspectives on spirits and sorcery’s threat. It also analyses their commitment to classical Bantu-African healing cults, along with their parallel consulting physicians and healers. By sharing the Yakaphones’ life-world, the analysis highlights their body-group-world weave, interlaced by the principle of co-resonance. A phenomenological and perspectivist look unfolds the local actors’ views, thereby disclosing the Bantu-African genius and setting for a major reversal of perspectives. Indeed, seeing 'here' from 'there' allows the author to uncover some alienating dynamics at work in his native Belgian Flemish-speaking culture. To better grasp the realm of life beyond the speakable and factual reasoning, the approach occasionally turns to the later Lacan’s focus on the unconscious desire, the body and its affects. The book addresses students and researchers in the humanities and, more broadly, all those immersed in the heat of the encounter with the culturally different.
