Abstract: A population of one billion people has the potential for enormous impact on the world food supply, but demographic and food production data for the People's Republic of China have been difficult to obtain. In an effort to fill this gap, two papers are presented which attempt ot synthesize and analyze as much information as is available and make predictions of probable trends in agriculture and related fields in the year 2000 and for the 1985 grain program. Records from 1952-77 are used to estimate cultivated land, animals, energy consumption, farm machinery, fertilizer, and output of grains, soybeans and cotton. The effects of industrailization and resources are considered. Trends are toward population control, although total demand will continue to grow; emphasis on agriculture seems to indicate that production will be capable of keeping up with demand, may result in some dietary improvement, but will not provide for emergency supplies.
An understanding of the immune system is central to the understanding of how the body interacts with its surroundings. Presenting an insight into this biological system, this book leads students through both innate and adaptive immunity, how infection is detected and how the cells of the immune system interact to generate a response.
This book constitutes the refereed proceedings of the International Conference on Spatial Information Theory, COSIT 2005, held in Elliottville, NY, USA in September 2005. The 30 revised full papers presented were carefully reviewed and selected from 82 submissions. The papers are organized in topical sections on vagueness, uncertainty, and gradation; paths and routes; ontologies and semantics; ontologies and spatial relations; spatial reasoning: cognitive maps and spatial reasoning; time, change, and dynamics; landmarks and navigation; geographic information, and spatial behaviour.
The technology used to ripen bananas is affected by a wide range of factors, including the cultivar, growing conditions, harvesting method, and maturity at which the fruit are harvested and handled. Various post harvest treatments applied to fruit can also impact ripening. While many textbooks have been dedicated to Musa (bananas and plantains), none have focused exclusively on the ripening process. The commercial ripening of bananas and the chemical changes that occur thereby are considered here in detail. In developed, temperate countries where bananas are imported, successful ripening technologies have evolved. Most bananas, however, are marketed locally in the country where they are grown, and often the ripening technologies used have economic and health implications. This brief offers an in-depth discussion of not only the implications of these technologies, but also of alternative ripening methods and their commercial applications. For an understanding of both the chemical basis by which bananas ripen and the technologies used to control the process, look no further than this essential text.

First released in 2007, the bestselling Transport Revolutions argued that land transport in the first half of the 21st century will feature at least two revolutions. One will involve the use of electric drives rather than internal combustion engines. Another will involve powering many of these drives directly from the electric grid - as trains and trolley buses are powered today - rather than from on-board fuel. Now available for the first time in paperback and updated with the most recent data, it sets out the challenges to our growing dependence on transport fuelled by low-priced oil. These challenges include an early peak in world oil production and profound climate change resulting in part from oil use. It proposes responses to ensure effective, secure movement of people and goods in ways that make the best use of renewable sources of energy while minimizing environmental impacts. Synthesizing engineering, economics, environment, organization, policy and technology in a detailed yet highly readable style, Transport Revolutions is essential reading for anyone working, studying or interested in transport and the environment.

The book presents the theory of diffusion-reaction equations starting from the Volterra-Lotka systems developed in the eighties for Dirichlet boundary conditions. It uses the analysis of applicable systems of partial differential equations as a starting point for studying upper-lower solutions, bifurcation, degree theory and other nonlinear methods. It also illustrates the use of semigroup, stability theorems and W2ptheory. Introductory explanations are included in the appendices for non-expert readers.The first chapter covers a wide range of steady-state and stability results involving prey-predator, competing and cooperating species under strong or weak interactions. Many diagrams are included to easily understand the description of the range of parameters for coexistence. The book provides a comprehensive presentation of topics developed by numerous researchers. Large complex systems are introduced for modern research in ecology, medicine and engineering.Chapter 3 combines the theories of earlier chapters with the optimal control of systems involving resource management and fission reactors. This is the first book to present such topics at research level. Chapter 4 considers persistence, cross-diffusion, and boundary induced blow-up, etc. The book also covers traveling or systems of waves, coupled Navier-Stokes and Maxwell systems, and fluid equations of plasma display. These should be of interest to life and physical scientists.
