Immune or immunological tolerance is the process by which the immune system does not attack an antigen. It occurs in three forms: central tolerance, peripheral tolerance and acquired tolerance. Central tolerance is immunological tolerance developed during T and B cell differentiation. Peripheral tolerance is immunological tolerance developed after T and B cells mature and enter the periphery. Acquired or induced tolerance is the immune system's tolerance for external antigens. This book presents the latest research from around the world.
Food and raw material for its production was generally produced via the traditional agriculture. On the other hand, novel chemicals were manufactured in the laboratory or extracted from plant and animal sources. However, as the world population is steadily in creasing, there is a decrease in traditional agriculture productivity and concerns are also expressed over the damage inflicted to the environment and restrictions that might be en forced in food production. At the same time, there is an increasing demand for high qual ity agricultural products as well as for food ingredients related to both the traditional or newly discovered nutrients or phytochemicals. Trends and developments,~n the ...
This book is a compendium of knowledge, experience and insight on agriculture, biotechnology and development. Beginning with an account of GM crop adoptions and attitudes towards them, the book assesses numerous crucial processes, concluding with detai
The 10th IAPTC&B Congress, Plant Biotechnology 2002 and Beyond, was held June 23-28, 2002, at Disney's Coronado Springs Resort, in Orlando, Florida, USA. It was attended by 1,176 scientists from 54 countries. The best and brightest stars of international plant biotechnology headlined the scientific program.

The construction and operation of highways has a significant impact on the environment. While such impact is impossible to avoid, modern highways are constructed and landscaped to minimise these impacts as far as possible. Good landscaping minimises the impact on those living or working close to the highway, while at the same time regenerating the natural landscape disturbed during construction. Using as its background the successful landscape design of the Nanjing-Hangzhou Expressway in Jiangsu Province, China, which opened to traffic in 2007, Highway Landscape Design includes reference to all aspects of the landscaping of highways, including interchanges, embankments, central reservations,...
The first of its kind, this collection of critical essays opens up new venues in the comparative study of science and culture by focusing on the formative decades of modern China in the late nineteenth and first half of the twentieth century. It provides a wide-ranging examination of the cultural and intellectual history of science and technology in modern China.From anti-imperialism to the technology of Chinese writing, the commodification of novelties to the rise of the modern professional scientist, new lexica and appropriations of the past, the contributors map out a transregional and global circuitry of modern knowledge and practical know-how, nationalism and the amalgamation of new social practices. Contributors include: Iwo Amelung, Fa-ti Fan, Shen Guowei, Danian Hu, Joachim Kurtz, Eugenia Lean, Thomas S. Mullaney, Hugh Shapiro, Grace Shen, and Jing Tsu.
