Sommario/riassunto

The first unified treatment of experimental and theoretical advances in low-temperature chemistry Chemical Dynamics at Low Temperatures is a landmark publication. For the first time, the cumulative results of twenty years of experimental and theoretical research into low-temperature chemistry have been collected and presented in a unified treatment. The result is a text/reference that both offers an overview of



the subject and contains sufficient detail to guide practicing researchers toward fertile ground for future research. Topics covered include:* Developmental history* Formulation

Sommario/riassunto

"This book describes fluorocarbons gases' preparation process, properties, applications and their evolution over time. The impact of fluorocarbons on the ozone layer and global and the development to mitigate those effects have been specially emphasized. The first major industrial fluorinated compound was developed in the 1920's, to replace ammonia and sulfur dioxide refrigerants, at the General Motors Frigidaire Division by Thomas Midgley, Jr. and Albert Leon Henne. They developed a family of fluorocarbons trademarked Freon® for auto air conditioning units revolutionizing the auto industry. Other applications were developed over time including fire extinguishers, propellants, blowing agents, cleaners, anesthesia, artificial blood and others impacting every facet of life. In spite of being in broad global use for nearly a century, fluorocarbon gases have gone through great evolution during the last few decades. In the 1980s it was discovered chlorofluorocarbon (CFC) gases are harmful to the ozone layer, mainly because of their chlorine content. Chlorine was released in the upper atmosphere when chlorofluorocarbon molecules were broken down by



the high energy cosmic radiation. CFCs were progressively banned following the Montreal Protocol of 1987. CFCs were replaced by fluorinated gases containing either less chlorine (hydrofluoro-chlorocarbons, or HCFCs), which are much less damaging (about 90% less) to the ozone layer or with fluorinated gases containing no chlorine, i.e. hydrofluorocarbons or HFCs. HFC have no impact on the ozone layer but impact global warming detrimentally. HFCs are usable without need for changes to the existing refrigeration or air conditioning installations. More recently hydrofluoroolefins (HFOs), which have little or no negative impact on global warming, have been developed to replace or reduce the use of HFCs. HFOs are used as single compounds or in blends. Research and development continues to develop and replace the HCFCs and HFCs completely with environmentally friendly products. Concise Handbook of Fluorocarbon Gases presents a reference and text for the commercial fluorocarbon gases which have great many application in a wide range of industries such as refrigeration and air conditioning, as well as consumer products"--

Sommario/riassunto

"Writing a book about recess could be a very questionable endeavor for a serious academic psychologist. At first blush it seems to be a pretty trivial topic. It's the time during the school day where there's a break from what's typically considered the most serious work of the day--reading, writing, and arithmetic. Reflecting this trivial tenor, it's also that time of the school day that kids--perhaps only half jokingly--say is their favorite part of school. This perception has lead many schools to question the role of recess in the school day. This book is an attempt to broach two views of recess--the perceived value of recess and the



movement to eliminate or reduce the school recess period from the primary school day. Due to tightened school budgets and the emphasis on testing, many elementary schools eliminate recess, gym classes, and play periods to the developmental detriment of the very children the schools are supposed to serve. Author Anthony Pellegrini has conducted a number of careful studies regarding student attentiveness and performance within programs that have recess periods, and those that don't. The data show that students need recess in order to blow off energy and interact with each other in the unstructured recess environment in order to grow socially. The goal of Recess is to help readers realize the importance of recess and counter the trend to eliminate it from schools. This book appeals to academics, teachers, administrators, and parents."--Provided by publisher.
