Oil and Security : A World Beyond Petroleum
This book examines the economic impact of changes in the global demand and supply for fossil fuels both on the major producers in Middle Eastern countries around the Persian Gulf, other producers, as well as the world at large. The economic, social and political life of most countries is not only intimately linked to and influenced by the energy market but also affected by historical developments. Among other issues, it shows how the economic, social and political development of societies in Arabia, the peoples of the Arab Peninsula are influenced by their historic and cultural environment, and what the future may bring to this region when their principal economic assets, petroleum and gas, start to lose markets as alternative sources of fossil fuel, alternative, and renewable energy supply the bulk of global energy needs. It also describes how changing fossil fuel costs, access, security of supply, and environmental impacts may affect future economic, social, and political developments as well as technological advances and changes in priorities.
Nutrition of cancer patient
According to world statistics, nutrition is estimated to contribute to about one-third of preventable cancers, nearly the same amount as the contribution of smoking. It is defined as the processes by which living organisms' intake of food and drink is used by the body for fuel, growth, reproduction, and the overall maintenance of health. Thus, sufficient nutritional consumption is essential for well-being. Consequently, it is an important part of life, cancer treatment, recovery, and prevention; eating the necessary nutrients prior to, during, and after a cancer treatment would aid the patient in the recovery process. A healthy diet means a stable nourishment, and includes obtaining sufficient amounts of essential nutrients (vitamins, minerals, protein, carbohydrates, fat, and water) the body needs. Inadequate intake of essential vitamins and minerals might explain the epidemiological findings that people who eat only small amounts of fruits and vegetables have an increased risk of developing cancer.
Nuclear Energy : Principles, Practices, and Prospects
The world faces serious difficulties in obtaining the energy that will be needed in coming decades for a growing population, especially given the problem of climate change caused by fossil fuel use. This book presents a view of nuclear energy as an important carbon-free energy option. It discusses the nuclear fuel cycle, the types of reactors used today and proposed for the future, nuclear waste disposal, reactor accidents and reactor safety, nuclear weapon proliferation, and the cost of electric power. To provide background for these discussions, the book begins with chapters on the history of the development and use of nuclear energy, the health effects of ionizing radiation, and the basic physics principles of reactor operation. The text has been rewritten and substantially expanded for this edition, to reflect changes that have taken place in the eight years since the publication of the first edition and to provide greater coverage of key topics. These include the Yucca Mountain repository plans, designs for next-generation reactors, weapons proliferation and terrorism threats, the potential of alternatives to nuclear energy, and controversies about low-level radiation.
Nuclear back-end and transmutation technology for waste disposal : Beyond the Fukushima accident
Covers essential aspects of transmutation technologies, highlighting especially the advances in Japan. The accident at the Fukushima Daiichi Nuclear Power Plant (NPP) has caused us to focus attention on a large amount of spent nuclear fuels stored in NPPs. In addition, public anxiety regarding the treatment and disposal of high-level radioactive wastes that require long-term control is growing. The Japanese policy on the back-end of the nuclear fuel cycle is still unpredictable in the aftermath of the accident. Therefore, research and development for enhancing the safety of various processes involved in nuclear energy production are being actively pursued worldwide.
Nitrogen Cycling in the Americas : Natural and Anthropogenic Influences and Controls
The rate of creation of reactive nitrogen (NR) on the earth has dramatically increased in the last half century mainly due to the production of N-fertilizer through the Haber-Bosch process, fossil fuel combustion, and the cultivation of plants that fix N from the atmosphere. The anthropogenic production of NR has been especially high in developed countries of the temperate zone, such as the USA and Canada, where severe eutrophication of estuaries and coastal zones, acidification of lakes and streams, loss of biodiversity, and reduced forest productivity have become common environmental problems associated with increasing nitrogen loads to ecosystems. This book presents a series of studies from across the Americas whose aim is to highlight key natural processes that control nitrogen cycling as well as discuss the main anthropogenic influences on the nitrogen cycle in both the tropical and temperate regions of the Americas.

Modern architecture and climate design before air conditioning
explores how leading architects of the twentieth century incorporated climate-mediating strategies into their designs, and shows how regional approaches to climate adaptability were essential to the development of modern architecture. Focusing on the period surrounding World War II'before fossil-fuel powered air-conditioning became widely available'Daniel Barber brings to light a vibrant and dynamic architectural discussion involving design, materials, and shading systems as means of interior climate control. He looks at projects by well-known architects such as Richard Neutra, Le Corbusier, Lúcio Costa, Mies van der Rohe, and Skidmore, Owings, and Merrill, and the work of climate-focused architects such as MMM Roberto, Olgyay and Olgyay, and Cliff May. Drawing on the editorial projects of James Marston Fitch, Elizabeth Gordon, and others, he demonstrates how images and diagrams produced by architects helped conceptualize climate knowledge, alongside the work of meteorologists, physicists, engineers, and social scientists. Barber describes how this novel type of environmental media catalyzed new ways of thinking about climate and architectural design.

Micromanufacturing : International Research and Development
We have come to know that our ability to survive and grow as a nation to a very large degree depends upon our sci- tific progress. Moreover, it is not enough simply to keep abreast of the rest of the world in scientific matters. We 1 must maintain our leadership. President Harry Truman spoke those words in 1950, in the aftermath of World War II and in the midst of the Cold War. Indeed, the scientific and engineering leadership of the United States and its allies in the twentieth century played key roles in the successful outcomes of both World War II and the Cold War, sparing the world the twin horrors of fascism and tota- tarian communism, and fueling the economic prosperity that followed.
Measuring Methane Production from Ruminants
The world’s livestock sector is amidst a major transformation, fuelled by high demand for meat and milk, which is likely to double over the next two decades in developing countries. The challenge is to enhance animal productivity without adversely affecting the environment. A key to this is reducing methane emissions from ruminants. The major limitation to ruminant production in many tropical regions of Africa, Asia and Latin America, where a large proportion of the global ruminant population is located, is poor nutrition. The productivity of animals is restricted by the low nitrogen and high fibre content of the native grasses and crop residues, which form the basis of the diets in these regions. Animals on these types of diets emit more methane than animals fed better quality temperate forages. These methane emissions represent a loss of digestible energy to the animal (up to 15%) as well as a threat to the environment.The challenge is to devise nutritional strategies and identify dietary components, particularly from locally available plant resources, that reduce methane emissions.
