Описание: This book is an introduction to radioactivity and aerosols for the scientifically literate reader with little or no previous exposure to either of these subjects. It provides a step-by-step introduction to radioactive aerosols from the physical science perspective, with coverage of such topics as indoor radon decay products, radioactive aerosols as tracers of atmospheric processes, indoor and outdoor models of aerosol transport, fallout from nuclear weapons and reactor accidents, and measurement of radioactivity and aerosols. Audience: Although it includes references to the research literature, it is not designed as a research monograph for specialists. Rather, it is directed at an interdisciplinary audience at the advanced undergraduate science level and higher who want an introductory, but rigorous, presentation of the core material of this subject. It is suitable for self study or for use as a main or supplemental textbook. It should be useful to a range of students in aerosol science, health physics, environmental science, nuclear engineering, and the atmospheric sciences. It should also be valuable to `crossover' professionals - professionals in other areas of science and engineering - who want a readable, self-contained introduction to radioactive aerosols. Many worked examples, and more than a hundred exercises and problems with answers, are provided.

Описание: The topic of photocatalysis is becoming increasingly important due to its essential role in many of today's environmental and energy-source problems. This book gives a comprehensive treatment of photocatalysis in three parts. The first part presents a brief introduction to the principles and fundamental aspects of photocatalysis including photoelectric chemical semiconductors. Part II describes applications to environmental cleaning, such as water purification and cleaning of the atmosphere. Part III discusses applications to photoenergy conversion, for example water decomposition with TiO2, semiconductors and metal complexes. Serving as a timely and convenient reference source including exciting new advances, the book will appeal to academic and industrial researchers as well as graduate and senior undergraduate students in the fields of photochemistry and photocatalysis.
Описание: Upon a synthesis of the technology of Combustion in Piston Engines, its past, present and future, the book provides a recipe for its advancement. Engines of the future are visualized as featuring distributed combustion executed by means of PJI&I (Pulse Jet Injection and Ignition) actuators, modulated by MECC (Micro-Electronically Controlled Combustion) systems in response to signals provided by pressure sensors. To assist in the development of such engines, the book provides the method of pressure diagnostics вЂ“ an analytical technique for interpreting the signal provided by a pressure sensor to assess the effectiveness with which fuel is utilized in an engine cylinder, and to monitor the operation of MECC in optimizing the performance of a PJI&I system. It is on this basis that a demonstration is produced of a representative car engine, for which, by the use of these systems, the formation of pollutants can be reduced by orders of magnitude, while the consumption of fuel is halved.
Описание: This book reviews technological applications of aerosol science together with the current scientific status of aerosol modeling and measurements. The aim is to identify available current information on the effects of aerosols on human health.
Описание: Springer/Praxis have a successful mini program of books on various aspects of light scattering, and now have a journal "Light Scattering Review" under consideration proposed by Alex Kokhanovsky. The atmospheric air contains not only gases but also various types of airborne particles (known as aerosols) ranging from dust grains to microbes. These small particles influence atmospheric visibility, the thermodynamics of the atmosphere, and they are also of great importance in any consideration of climate change problems. Aerosols may also be responsible for the loss of harvest, health problems among humans and ecological disasters. Therefore, it is of great importance to study aerosol properties on a global scale. Such studies ultimately should be based on global observations using instruments positioned on the space platforms.
Описание: Human exposure to aerosols, through inhalation or in working or ambient environments, may lead to a wide range of adverse health effects, including lung disease and other conditions resulting from toxic materials in the body.

Описание: The energy flow from the atmosphere to the ocean generates an aerodynamically rough ocean surface. If the energy flow is sufficiently strong, in some points of the surface, waves loose their stability and eventually break in the form of whitecaps of various scales. The turbulence associated with the breakers produce the aerosols in the form of jet and film drops from the bursting of air bubbles. The aerosol droplets transfer water vapour, heat, pollutants and bacteria through the air-water interface. They are easily transported by wind over large distances. In this way, marine aerosols influence the optical features of the atmosphere, which are of fundamental importance for the remote sensing of the surface and they play an important role in climate variations.The amount of marine aerosols rising from the sea surface depends on the coverage of the sea by breaking waves or whitecaps, and the rate of intensity of breaking. Much of the uncertainty in sea aerosols production and gas transfer arises from weaknesses in the parameterization of wave breaking and related processes.This book describes the mechanisms of wave breaking, based on the theoretical and experimental achievements published in literature as well as on the author's experience. Special attention is paid to selection of the wave breaking criteria, and to development of the wave breaking probability and estimation of the energy dissipation due to breaking.Secondly, the book examines the relationships between wave breaking and marine aerosol fluxes and gas transfer from the sea surface. In general, an amount of marine aerosol rising from the sea surface depends on the coverage of the sea by breaking waves or whitecaps, and on the rate of intensity of breaking. The wind speed, commonly used in prediction of the whitecaps coverage, is only one of the factors determining the wave energy and probability of the breaking occurrence. It is more appropriate to find the linkage between the percentage of sea surface covered by whitecaps and the sea state characteristics (i.e. the significant wave height and spectrum peak frequency) and the amount of energy dissipated during wave breaking and its relationship with the aerosol fluxes.

Описание: This monograph provides a unique and comprehensive coverage of the nature and atmospheric role of carbonaceous aerosol particles, these big unknowns of the global atmosphere. Even the concept of carbonaceous aerosol has just recently grown out of atmospheric pollution studies, without ever being anchored to solidified nomenclature and terminology. It is beyond any doubt that no major breakthrough can be expected in resolving climate issues without a better understanding of the role carbonaceous particles play in the global atmosphere. This monograph may serve as an indispensable reference for all those interested in virtually any aspects of global atmospheric sciences, especially for those who are stakeholders in inadvertent climate modification. Thus atmospheric chemists, physicists, meteorologists, and modellers may well find this monograph a thought-inspiring and sometimes provocative overview of all global phenomena affected by or related to carbonaceous aerosol. An anticipated advantage of this monograph is that it brings together these diverse atmospheric phenomena under the umbrella of carbonaceous aerosol in an interdisciplinary way, which is a prerequisite of resolving global scientific issues.
Описание: Aerosols play a critical role in a broad range of scientific disciplines, such as atmospheric chemistry and physics, combustion science, drug delivery and human health. This thesis explores the fundamentals of a new technique for capturing single or multiple particles using light, and for characterising these particles by Raman or fluorescence spectroscopy. The outcome of this research represents a significant development in optical manipulation techniques, specifically in optical tweezing. These findings can be applied to studies of the mass accommodation of gas-phase water molecules adsorbing onto a water surface. Not only is this a fundamental process of interest to physical chemists, but it is important for understanding the role of aerosol particles in the atmosphere, including their ability to become cloud droplets. This new strategy for investigating aerosol dynamics is fundamental in helping us understand the indirect effect of aerosols on the climate.

Описание: This book is about radioactive gases and particles which are dispersed in the environment, either from natural causes, or following nuclear test and accidental emissions. In the first five chapters of this book, the formation and properties of radioactive aerosols are described. Radon, which is of natural origin, is treated at some length, because its contribution to background radiation dose is important. Chapters describe the release of fission products, tritium and plutonium, in bomb tests and nuclear accidents. Particular reference is made to the pathways leading via agricultural products to man. The emphasis then changes to cover experimental aspects of radioactive aerosols. For example, problems in micrometeorology, the study of mass transfer, the mechanics of the human lung and uptake of lead from motor exhausts. Arthur Chamberlain has worked at the Atomic Energy Research Establishment at Harwell for thirty years as the leader of the Aerosol Group. It is a unique exposition and will be used by chemists, geographers, environmentalists as well as governments and other agencies involved in the nuclear debate.
