div Biological diversity is as crucial in agriculture as it is in nature, and it is equally important to the economic health of both industrial and nonindustrial societies. This book offers a sweeping assessment of crop diversity and the potential for its preservation. Stephen B. Brush develops a framework for investigating biological diversity in agriculture that focuses on the knowledge and practice of farmers, and he shows how this human ecology perspective can be applied to three global issues that affect crop resources. Brush defines the dimensions of crop diversity and outlines the essential questions surrounding it. He describes the techniques used to maintain diversity in major crops of three cradles of agriculture in which he has worked: potatoes in the Peruvian Andes, maize in Mexico, and wheat in Turkey. Finally, he explores the policy issues surrounding genetic erosion of crop varieties, conservation of crop diversity, and ownership of genetic resources. /DIV

A complete guide to electric vehicle design, operation, and adoption This hands-on resource thoroughly explains the technologies and techniques involved in the design and operation of today’s electric vehicles. Originally written for use in a course co-taught by the authors at Stanford University, Electric Vehicle Engineering discusses the physics of vehicle motion; the electrical principles on which motors rely; the chemistry, operation, and charging of lithium-ion batteries; the design and operation of motor controllers; the energy efficiency and environmental impact of electric vehicles; and the policy and economics affecting their adoption. After teaching you the theory, the authors will guide you through a hands-on project in which you will build a model electric car from the ground up with a hand-wound electric motor of your own design. Coverage includes: Introduction to electric vehicles Electric vehicle history Vehicle dynamics Electric motors Lithium-ion batteries Controllers Well-to-wheels energy and emissions analysis Electric vehicle policies and economics Future prospects

While Johnson charged that Milton "unhappily perplexed his poetry with his philosophy," Stephen M. Fallon argues that the relationship between Milton's philosophy and the poetry of Paradise Lost is a happy one. The author examines Milton's thought in light of the competing philosophical systems that filled the vacuum left by the repudiation of Aristotle in the seventeenth century. In what has become the classic account of Milton's animist materialism, Fallon revises our understanding of Milton's philosophical sophistication. The book offers a new interpretation of the War in Heaven in Paradise Lost as a clash of metaphysical systems, with free will hanging in the balance.
