Book Description
The question of whether the earth's climate is changing in some significant human-induced way remains a matter of much debate. But the fact that climate is variable over time is well known. These two elements of climatic uncertainty affect water resources planning and management in the American West. Managing Water Resources in the West Under Conditions of Climate Uncertainty examines the scientific basis for predictions of climate change, the implications of climate uncertainty for water resources management, and the management options available for responding to climate variability and potential climate change.

Book Description
Underwater Physiology is a collection of papers that deals with the physiologically limiting effects of undersea, high pressure exposure ranging from fundamental biological reactions, through integration of physiological stresses, and to limits actually experienced in deep diving. Papers discuss oxygen, the mechanisms of toxicity, and the effects of oxygen on cells and systems such as its pathological and physiological influences in the neurosensory ocular tissue. Other papers discuss the physical effects of pressure and gases on cellular function, protein structure, and the possibility of alleviating symptoms through the administration of drugs. Tests in mice show that various gases exhibit qualitative and semi-quantitative differences in the characteristics of sickness, reactions to hypoxia, and the time before the onset of symptoms. A computer, programmed for nonlinear gas transfer and other variables, running in real time can compute directly from the breathing mixture and provide a real time solution to decompression sickness under various conditions. A combined therapeutic approach, recompression and dextran (an effective lipemic clearing agent) should be capable of treating decompression sickness in humans. Other papers investigate the influence of inert gases and pressure on the central nervous system, as well as, situations in undersea and manned chamber operations. This collection can prove valuable for physiologists, biochemists, cellular biologists, and researchers involved in deep sea diving.

Book Description
The signals are everywhere that our planet is experiencing significant climate change. It is clear that we need to reduce the emissions of carbon dioxide and other greenhouse gases from our atmosphere if we want to avoid greatly increased risk of damage from climate change. Aggressively pursuing a program of emissions abatement or mitigation will show results over a timescale of many decades. How do we actively remove carbon dioxide from the atmosphere to make a bigger difference more quickly? As one of a two-book report, this volume of Climate Intervention discusses CDR, the carbon dioxide removal of greenhouse gas emissions from the atmosphere and sequestration of it in perpetuity. Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration introduces possible CDR approaches and then discusses them in depth. Land management practices, such as low-till agriculture, reforestation and afforestation, ocean iron fertilization, and land-and-ocean-based accelerated weathering, could amplify the rates of processes that are already occurring as part of the natural carbon cycle. Other CDR approaches, such as bioenergy with carbon capture and sequestration, direct air capture and sequestration, and traditional carbon capture and sequestration, seek to capture CO2 from the atmosphere and dispose of it by pumping it underground at high pressure. This book looks at the pros and cons of these options and estimates possible rates of removal and total amounts that might be removed via these methods. With whatever portfolio of technologies the transition is achieved, eliminating the carbon dioxide emissions from the global energy and transportation systems will pose an enormous technical, economic, and social challenge that will likely take decades of concerted effort to achieve. Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration will help to better understand the potential cost and performance of CDR strategies to inform debate and decision making as we work to stabilize and reduce atmospheric concentrations of carbon dioxide.

Book Description
Physiology for Dental Students presents a combined view of physiological mechanisms and physiological systems. It discusses the oral importance of basic physiology. It addresses physiological principles and specific types of cells. Some of the topics covered in the book are the movements of materials across cell membranes; the fluid compartments of the body; the major storage of body water; histological and ultrastructural appearance of the salivary glands; the secretion of substances into the urine in the kidney; and the total osmotic activity of plasma. The morphology of the red blood cells is fully covered. The factors necessary for red blood cell development is discussed in detail. The text describes in depth the mechanical properties of smooth muscle. The process of breathing and the elasticity of lungs are presented completely. A chapter is devoted to the parts of the central nervous system. The book can provide useful information to dentists, doctors, students, and researchers.

Book Description
Between 1958 and 2008, the CO2 concentration in the atmosphere increased from 316 to 385 ppm. Continued increases in CO2 concentration will significantly affect long-term climate change, including variations in agricultural yields.

Book Description
U.S. Navy personnel who work on submarines are in an enclosed and isolated environment for days or weeks at a time when at sea. Unlike a typical work environment, they are potentially exposed to air contaminants 24 hours a day. To protect workers from potential adverse health effects due to those conditions, the U.S. Navy has established exposure guidance levels for a number of contaminants. The Navy asked a subcommittee of the National Research Council (NRC) to review, and develop when necessary, exposure guidance levels for 10 contaminants. Overall, the subcommittee found the values proposed by the Navy to be suitable for protecting human health. For a few chemicals, the committee proposed levels that were lower than those proposed by the Navy. In conducting its evaluation, the subcommittee found that there is little exposure data available on the submarine environment and echoed a previous recommendation from an earlier NRC report to conduct monitoring that would provide a complete analysis of submarine air and data on exposure of personnel to contaminants.

Book Description
The importance of carbon dioxide extends from cellular to global levels of organization and potential ecological deterioration may be the result of increased CO2 in our atmosphere. Recently, the research emphasis shifted from studies of photosynthesis pathways and plant growth to ground-breaking studies of carbon dioxide balances in ecosystems, regions, and even the entire globe. Carbon Dioxide and Terrestrial Ecosystems addresses these new areas of research. Economically important woody ecosystems are emphasized because they have substantial influence on global carbon dioxide balances. Herbaceous ecosystems (e.g., grasslands, prairies, wetlands) and crop ecosystems are also covered. The interactions among organisms, communities, and ecosystems are modeled, and the book closes with an important synthesis of this growing nexus of research. Carbon Dioxide and Terrestrial Ecosystems is a compilation of detailed scientific studies that reveal how ecosystems generally, and particular plants specifically, respond to changed levels of carbon dioxide. - Contributions from an international team of experts - Empirical examination of the actual effects of carbon dioxide - Variety of terrestrial habitats investigated - Specific plants and whole ecosystems offered as studies
