Protecting the environment and conserving natural resources by using materials in cyclic loopsOne of the most urgent problems facing the world today is environmental sustainability. Current practices of pollution control, waste treatment, and environmental protection are not only hugely expensive and a burden on development but also unsustainable in the long run for their steady depletion of the world's natural resources. Any solutions must have proven economic benefits, be technologically viable, and meet prevailing environmental and social perspectives. The main objective of this new set of studies is to describe methods that help to protect the environment and conserve natural resources. This can be achieved by applying the 'cradle-to-cradle' concept, which aims to use materials in closed cyclic loops without generating any type of waste or pollution. The authors provide the reader with an introduction to basic concepts of sustainable development, describe the mechanisms and benefits of related technologies, and suggest potential uses on a practical level by examining innovations developed in the mechanical engineering laboratories of the American University in Cairo. Particular focus is placed on innovation as a vital means of attaining sustainability. A timely contribution to the debate on environmentally sustainable practices, this book will be indispensable to environmentalists, scientists, economists, engineers, development specialists, and policy-makers, as well as being of interest to the lay reader.1.

Ferrets, Rats and Traps, originally published in 1897 as: "Ferrets Their Management in Health and Disease." By Nicholas Everitt. This hitherto rare and much sought after book was the first comprehensive work to be written on the subject of ferrets and ferreting in England. Over 200 pages of content deal with every aspect of the ferret and its use both as a working animal and for pleasure or profit. The author, an acknowledged expert in his field, wrote numerous short articles on "Ferrets and All About Them" for early editions of The Shooting Times. By popular demand he eventually reprinted them in book form, with additions and alterations, and published this to much critical acclaim in March 1897. Read Country Books has now re-published "Ferrets" in its original format, including the interesting black and white illustrations of ferreting, ferret equipment, and vermin traps. The books contents are arranged in two sections. The first 160 pages deal with the origins of the ferret and also discuss the polecat, weasel, stoat and marten. Also included in this section are recommendations for ferret hutches, yards and courts, with illustrations of these and also ferret traps and working boxes produced by trap manufacturers of the time. Other chapters deal with ferret management, breeding and rearing, including advice on ailments and disease. The comprehensive chapters on working ferrets are a fascinating record of rural sport in the late 19th century, and will appeal greatly to todays ferreters. Further chapters on the laws relating to ferrets and ferreting will prove of historical interest. Section two of the book deals with trapping and with rats, their origins, habits and control. The prevention methods discussed include ferreting, trapping, shooting, poisoning etc. Much mention is made of various manufacturers and their traps, with some of them being illustrated. This fascinating book ends with a descriptive chapter of an 1890's November days ferreting.

Comparing the Zimbabwean and Japanese agrarian experience may sound impossible. Still, the similarities in the socio-economic and political realities of their respective radical land reforms and grain policies provide scope for such an endeavour. This book examines the aftermath of Japan�s radical land reform and the development of her cooperatives. It then compares it to the nature and character of the Zimbabwe post-land reform agrarian structure. The author collected and analysed data from three villages in Japan, and three in Zimbabwe to understand different types of cooperatives, their growths, and constraints. Three distinct types of cooperatives emerged from Japan�s 70-year experience in cooperative development. One of these three was identified as providing more relevant lessons necessary for restructuring the British-Indian type of cooperatives currently obtaining in Zimbabwe. The central argument is that the radical Fast-Track Land Reform Programme provided a rare platform (as it did in Japan) to develop robust, genuine grassroots cooperatives from below. Based on a global political economy reading of agricultural production, the book sieves the pros and cons of the Japanese agricultural cooperative system with knowledge systems from the Zimbabwe movement to advance a new agricultural cooperative development framework for Zimbabwe and other post-colonial states.

La maintenance moderne ne peut plus se limiter à être corrective ou préventive, mais se doit d’être proactive et prédictive. Les techniques de maintenant demandent une polyvalence qui ne peut être uniquement maîtrisée par un seul ingénieur, mais plutôt par une équipe multidisciplinaire. Cette super équipe de maintenance aura une compétence dans des domaines techniques complémentaires et saura planifier, organiser, maîtriser la statistique et les calculs de durée de vie et utiliser les techniques d’essais non destructifs. La surveillance des vibrations de machines est un art en soi, qui permet de diagnostiquer les défauts potentiels, d’en évaluer la gravité et de prendre les mesures correctrices nécessaires. L’objectif de cet ouvrage est de fournir à l’équipe de maintenance une formation multidisciplinaire en présentant, avec une complexité croissante, les différentes notions nécessaires à l’accomplissement de sont travail. Dans cet ouvrage, le lecteur trouvera une panoplie complète des techniques qui doivent être maîtrisées pour accomplir la tâche de maintenant, dont la fiabilité des équipements, l’organisation des tâches de maintenance et le suivi de l’état de santé d’une machine par la mesure de ses vibrations. Ce livre s’adresse non seulement aux étudiants des écoles d’ingénierie, mais également aux techniciens supérieurs ainsi qu’aux professionnels s’occupant des tâches techniques de maintenance dans l’industrie. Il aborde certes des notions mathématiques, mais également des concepts physiques et des méthodes pratiques pour servir de support à l’implantation d’une maintenance efficace.
