Many equations are present to provide a good theoretical background,?as well as numerous charts, graphs, figures, tables, and photos to summarize and illustrate the theoretical background in a practical presentation. Numerous appendices expand on the main text, a well thought-out index gives quick access to important concepts, and an extensive list of references provides further avenues of research for those wishing to extend their knowledge.Much of the environmental data and material response information has been adapted from published and unpublished scientific literature for use in this document.? It is the book form of the recently issued NASA Technical Handbook NASA-HDBK-4002A, March 3, 2011 (by the same authors).? In particular, this book can be used as the textbook form of that Handbook and its earlier sources, NASA Technical Paper 2361, 1984, and NASA Technical Handbook NASA-HDBK-4002, 1999 (both co-authored by the current authors).Since the original writing of the 2361 and 4002, there have been many developments in the understanding of spacecraft charging issues and mitigation solutions, as well as advanced technologies needing new mitigation solutions.? Solar cell technology, especially higher voltage arrays have been found to need new design approaches; these are described in detail in this new book.? Information about the space plasma environment has been studied more thoroughly; that information is in this new book.? New analytic computer codes have been developed to help analyze spacecraft charging; they are described and listed in this new book.? Spacecraft anomalies and failures have emphasized certain designs that are now known to be of greater importance than others; that knowledge is incorporated in this new book"--Provided by publisher.JPL Space Science and Technology SeriesSpace vehiclesElectrostatic chargingElectric dischargesPreventionSpace vehiclesElectrostatic charging.Electric dischargesPrevention.629.47SCI022000bisacshGarrett Henry B907699MiAaPQMiAaPQMiAaPQBOOK9910141250903321Guide to mitigating spacecraft charging effects2030454UNINA01947oam 2200433 450 991070373850332120180806143504.0(CKB)5470000002434337(OCoLC)911207532(EXLCZ)99547000000243433720150619d2015 ua 0engurcn||||a||||txtrdacontentcrdamediacrrdacarrierAssociation between diagnosed ADHD and selected characteristics among children aged 4-17 years, United States, 2011-2013 /Patricia N.

Nanotechnology is not a completely new field; however, it is only recently that discoveries in this field have advanced so far as to warrant examination of their impact upon the world around us. Nanotechnology has direct beneficial applications for medicine and the environment, but like all technologies it may have unintended effects that can adversely impact the environment, both within the human body and within the natural ecosystem. How does the science move forward in a way that best protects the public and gets health and safety right the first time? Implications of Nanotechnology for Environmental Health Research identifies the areas in which additional research is needed and the processes by which changes can occur.NanotechnologyEnvironmental aspectsNanotechnologyCongressesNanotechnologyEnvironmental aspects.Nanotechnology610.28Goldman Lynn1806536Coussens Christine1804930Institute of Medicine (U.S.).Roundtable on Environmental Health Sciences, Research, and Medicine.MiAaPQMiAaPQMiAaPQBOOK9910971984103321Implications of nanotechnology for environmental health research4355848UNINA
