This book allows you to present scientific principles and simple mechanics through hands-on cooperative learning activities. Using inexpensive materials (e.g., tape, paper clips), students build simple machines-such as levers, pulleys, spring scales, gears, wheels and axles, windmills, and wedges-that demonstrate how things work. Activities have easy-to-locate materials lists, time requirements, and step-by-step directions (usually illustrated) on presentation. Ideas for bulletin boards, learning centers, and computer-assisted instruction are an added bonus.

Advances in technology are demanding ever-increasing mastery over the materials being used: the challenge is to gain a better understanding of their behaviour, and more particularly of the relations between their microstructure and their macroscopic properties. This two-volume work, of which this is the first volume, aims to provide the means by which this challenge may be met. Starting from the mechanics of deformation, it develops the laws governing macroscopic behaviour -- expressed as the constitutive equations -- always taking account of the physical phenomena which underlie rheological b

Designing new structural materials, extending lifetimes and guarding against fracture in service are among the preoccupations of engineers, and to deal with these they need to have command of the mechanics of material behaviour. The first volume of this two-volume work deals with elastic and elastoplastic behaviour; this second volume continues with viscoelasticity, damage, fracture (resistance to cracking) and contact mechanics. As in Volume I, the treatment starts from the active mechanisms on the microscopic scale and develops the laws of macroscopic behaviour. Chapter I deals with

The journals printed in this volume, covering the years 1852 to 1855, find Emerson increasingly drawn to the issues and realities of the pragmatic, hard-working nineteenth century. His own situation as a middle-aged, property-owning New Englander with a large household to support gave him a strong sense of everyday financial necessity, and his wide reading for his projected book on the English impressed him deeply with the worldly success that had conic to that unphiiosophieal people. The growing crisis over slavery at home, moreover, demanded the attention of every citizen, even one as relu

David Michaels is afraid. His palms sweat. His knees threaten to buckle. And his tongue, like his stomach, seems to be tied in knots. For David is due to give a series of presentations. His objective is to win support for his project to save sick children in Amazonia. Fortunately, help is at hand in the unlikely shape of Demosthenes, the 4th-century Greek orator. Under his tutelage, David overcomes his fears and learns how to create a powerful presentation. What he learns, he realises, can be applied to any presentation, large or small. By following David as he gradually masters the techniques

Food insecurity is a central concern and a fundamental challenge for human welfare and economic growth in Africa. Low agricultural production, results in low incomes, poor nutrition, vulnerability to risks and lack of empowerment. Land degradation and soil fertility depletion are considered the major threats to food security and natural resource conservation in sub-Saharan Africa (SSA). Investments in technology, policy and institutional reforms are needed to increase agricultural productivity to ensure food security and sustained national economies. Past research has generated numerous soil f

The emergence of Europe as a unified trading block has profound implications for those who do business with European countries. European Union Law is written for lawyers and business professionals who require information about the changes that are taking place as a result of the unification process in the member states of the European Union. Unlike other materials on Europe, this book is written primarily for lawyers outside the EU. The book serves three important functions: + It provides a comprehensive introduction to European law, law-making institutions and dispute settlemen
