The book presents new research in the area of biobased “green composites”. Biobased materials involve renewable agricultural and forestry feedstocks, including wood, agricultural waste, grasses and natural plant fibers. These lignocellulosic materials are composed mainly of carbohydrates such as sugar and lignin, cellulose, vegetable oils and proteins. Much research is concerned with renewable materials such as bamboo, vegetable fibers, soil composites and recycled materials such as rice husk ash and sugar cane ash. The general aim here is to use renewable and non-polluting materials in ways that offer a high degree of sustainability and preserve the remaining natural resources for futu...
Comprising a collection of papers from the 4th International Conference on Environmental and Economic Impact on Sustainable Development, the research studies included in this book consider the impact of economic constraints on the environment, taking into account the social aspects as well as the over-use of natural resources. The papers examine issues related to whether some forms of development are compatible with environmental protection, particularly in cases of possible serious contamination and toxicity. Uncontrolled development can result in damage to the environment in terms of the release of toxic substances and hazardous waste. Addressing problems of great importance, this book examines more constructive and progressive approaches to ensure sustainability. A major motivation is to learn from past failure, to avoid repeating similar mistakes, while attempting to prevent emerging threats to environmental and ecological systems. Fundamental to these concepts are the analysis of the inherent risk and the development of appropriate strategies.
La propuesta nace sobre la base de constituirse en una "primera aproximación a las casas bioclimáticas" y, tiene como propósitos, en relación con el tema planteado expresar algunas consideraciones e ilustrar sobre proyectos y obras internacionales y nacionales. Son sucintas reflexiones sobre lo que se considera arquitectura bioclimática, planteamos los principios que rigen la adecuación de las viviendas de interés social. Describimos las condicionantes a la que los arquitectos, científicos, técnicos y usuarios estuvieron sujetos, se logra una interacción en el proceso de diseño, de gestión y producción para alcanzar los objetivos. Exponemos la forma de pensar, saber y hacer casas bioclimáticas

Literally hundreds of languages world-wide have experienced direct or indirect Hispanisation during the heyday of the Spanish colonial empire. The number of languages which continue to borrow from Spanish on a daily basis is considerable especially in Latin America. This volume gives the reader a better idea of the range of contact constellations in which Spanish functions as the donor language. Moreover, the contributions to this collection of articles demonstrate that it is not only possible to compare the contact-induced processes in the (Hispanised) languages of Austronesia and the Americas. It is emphasized that one can draw far-reaching conclusions from the presented borrowing facts fo...
