Reviews the legislative history of the land grant system from its establishment in 1862 to the 1994 act conferring land grant status on Native American colleges. This book describes trends that have shaped agriculture - the shift of labour from farm to factory, reasons for and effects of increased productivity and specialization, and more.

Maintaining the United States' lead in information technology requires federal support of research in this area, most of which is funded under the High Performance Computing and Communications Initiative (HPCCI). This book provides 13 major recommendations for refining both HPCCI and support of information technology research in general.

Addresses the technical, health, regulatory, and social aspects of ground water withdrawals, water use, and water quality in the metropolitan area of Mexico City, and makes recommendations to improve the balance of water supply, water demand, and water conservation. This book also contains a Spanish-language translation of the English text.

Presents a dialogue between engineers and environmental scientists as they consider the many technical as well as social and legal challenges of ecologically sensitive engineering. This volume looks at the concepts of scale, resilience, and chaos, and is useful for policymakers, practitioners, researchers, educators, and students.

Reviews the structural design process and determines the elements, and capabilities required for a materials selection expert system to assist design engineers. This book also recommends the areas of expert system and materials modeling research and development required to devise a materials-specific design system.

Offers an examination of isotope production and availability, including the education and training of those who will be needed to sustain the flow of radioactive and stable materials from their sources to the laboratories and medical care facilities in which they are used.

Examines the state of the art in airborne geophysics as integrated with precise global positioning systems. This book outlines the scientific goals of focused effort in airborne geophysics, including advances in our understanding of solid earth processes, global climate change, the environment, and resources.

Examines the traditional US census. This book evaluates several radical proposals that have been made for changing the census, as well as other proposals for redesigning the year 2000 census. It also considers in the much-criticized long form, the role of race and ethnic data, and the need for and ways to obtain small-area data between censuses.

Discusses six competency based learning objectives for all medical school students, discusses the relevance of environmental health to specific courses and clerkships, and demonstrates how to integrate environmental health into the curriculum through published case studies, some of which are included in one of the book's three appendices.

What are the long-term results of weight-loss programs? How can people sort through the many programs available and select one that is right for them? This book strives to answer these questions. This book discusses short- and long-term safety consequences of weight loss, as well as clinical assessment of individual patients.

Explores what earth scientists are learning about the impact of large-scale environmental changes on ancient life - and how these findings may help us resolve several environmental controversies. This book is of interest to professionals in the earth sciences and the environmental community, as well as concerned policymakers.
