This book surveys recent developments in numerical techniques for global atmospheric models. It is based upon a collection of lectures prepared by leading experts in the field. The chapters reveal the multitude of steps that determine the global atmospheric model design. They encompass the choice of the equation set, computational grids on the sphere, horizontal and vertical discretizations, time integration methods, filtering and diffusion mechanisms, conservation properties, tracer transport, and considerations for designing models for massively parallel computers. A reader interested in applied numerical methods but also the many facets of atmospheric modeling should find this book of particular relevance.

In the past 15-20 years major discoveries have been concluded on potato biology and biotechnology. Important new tools have been developed in the area of molecular genetics, and our understanding of potato physiology has been revolutionized due to amenability of the potato to genetic transformation. This technology has impacted our understanding of the molecular basis of plant-pathogen interaction and has also opened new opportunities for the use of the potato in a variety of non-food biotechnological purposes.
This book covers the potato world market as it expands further into the new millennium. Authors stress the overriding need for stable yields to eliminate human hunger and poverty, while considering solutions to enhance global production and distribution. It comprehensively describes genetics and genetic resources, plant growth and development, response to the environment, tuber quality, pests and diseases, biotechnology and crop management. Potato Biology is the most valuable reference available for all professionals involved in the potato industry, plant biologists and agronomists.
-Offers an understanding of the social, economic and market factors that influence production and distribution
-Discusses developments and useful traits in transgenic biology and genetic engineering
-The first reference entirely devoted to understanding new advances in potato biology and biotechnology

The Great Houses of Chaco are in turmoil as the last survivors uncover the mystery and truth at the heart of their civilization. Lovers, warriors and rival clans born of an ancient American culture are catapulted to the brink of destruction by one warrior's urgent quest. From the sandstone mesas of the Southwest to chambered catacombs hidden beneath the desert city, Chaco reveals a land of sacrifice and other-worldly beauty shaken by a vision of the future.
