Download or read book ADVANCED SAMPLING AND ANALYSIS OF FINE PARTICULATES. Final Topical Report which Includes Semiannual for the Period of January 1, 1998 - June 30, 1998 written by and published by . This book was released on 1998 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sampling tests indicated that the polycarbonate filters were marginally acceptable for in-stack fine-particle collection because of their 230 F melting point as well as requiring carbon coating to reduce charging effects. Vitreous carbon substrates, although not porous, have acceptable thermal stability as well as acceptable levels of charging. A porous silver membrane filter is also being considered for future testing. Pure reference samples of secondary aerosols have been successfully been collected on vitreous carbon substrates with good dispersion and found suitable for direct examination by scanning electron microscope (SEM) without prior coating or preparation. These samples will be used to develop optimum SEM measurement and quantification techniques related to the analysis of fine secondary aerosols.

Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this study are to develop a sampling method to capture the fine particulate and classiyi the particulate according to their size and chemistry. When developing the sampling method, two criteria need to be met: 1) the particulate are randomly dispersed on the sampling media and 2) the sampling media can be put directly into a scanning electron microscope (SEM) for analysis to prevent any alteration of the particulate. Several methods for the sampling and analysis of fine particulate are to be tested. Each sampling test will be analyzed using the FPT technique for collecting the size, shape, and chemical composition of 1500 to 2000 individual fine particulate. The FPT data will be classified using cluster analysis and principal component analysis to provide a classification system for these particles. As reported previously, particulate samples were collected using the advanced hybrid particulate collector (AHPC) on the inlet port of the particulate test combustor (PTC) when the Absaloka coal was burned in early April. The samples were collected at the inlet rather than the outlet port because of the loading that was expected and the temperature at which the PTC was run. Samples at the inlet were expected to see a much greater particulate loading than at the outlet because of the efficiency of the particulate collection device on the PTC. Also, polycarbonate filters cannot withstand temperatures above 230oC for long periods of time; therefore, a quick loading time was required. The samples were briefly scanned and photographed using the SEM to determine the best particulate loading time. The particulate were too close together on the 20- and 30-second polycarbonate filters to be able to analyze individual particles. The particle dispersion on the vitreous carbon substrate appeared to be the best of the four samples. Aerosols were produced from pure 1.0 M aqueous solutions of NaCl, Na2S04, (NHq)2SOo, NHqNO~, and K20 (KOH) using a Tri-Jet Model 3460 aerosol generator and collected by direct impingement on a vitreous carbon substrate. Because NaCl is the normal aerosol produced with the generator, it was briefly examined using SEM to determine the degree of dispersion. Good dispersion with nearly all particulate size below 2 pm and the majority in the O.1-pm range was achieved with a substrate collection time of 2-3 minutes. The brief examination also demonstrated that the sample could be introduced directly into the SEM for analysis with no prior carbon coating or other preparation and that charging of the sample was minimal.

Download or read book Reducing Environmental Cancer Risk written by Suzanne H. Reuben and published by DIANE Publishing. This book was released on 2010-10 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though overall cancer incidence and mortality have continued to decline in recent years, cancer continues to devastate the lives of far too many Americans. In 2009 alone, 1.5 million American men, women, and children were diagnosed with cancer, and 562,000 died from the disease. There is a growing body of evidence linking environmental exposures to cancer. The Pres. Cancer Panel dedicated its 2008¿2009 activities to examining the impact of environmental factors on cancer risk. The Panel considered industrial, occupational, and agricultural exposures as well as exposures related to medical practice, military activities, modern lifestyles, and natural sources. This report presents the Panel¿s recommend. to mitigate or eliminate these barriers. Illus.
Book Synopsis Advances in the Study of Gas Hydrates by : Charles E. Taylor
Download or read book Advances in the Study of Gas Hydrates written by Charles E. Taylor and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book had its genesis in a symposium on gas hydrates presented at the 2003 Spring National Meeting of the American Institute of Chemical Engineers. The symposium consisted of twenty papers presented in four sessions over two days. Additional guest authors were invited to provide continuity and cover topics not addressed during the symposium. Gas hydrates are a unique class of chemical compounds where molecules of one compound (the guest material) are enclosed, without bonding chemically, within an open solid lattice composed of another compound (the host material). These types of configurations are known as clathrates. The guest molecules, u- ally gases, are of an appropriate size such that they fit within the cage formed by the host material. Commonexamples of gas hydrates are carbon dioxide/water and methane/water clathrates. At standard pressure and temperature, methane hydrate contains by volume 180 times as much methane as hydrate. The United States Geological Survey (USGS) has estimated that there is more organic carbon c- tained as methane hydrate than all other forms of fossil fuels combined. In fact, methane hydrates could provide a clean source of energy for several centuries. Clathrate compounds were first discovered in the early 1800s when Humphrey Davy and Michael Faraday were experimenting with chlorine-water mixtures.

This book was released on 2003-09 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This official history was originally printed in very small numbers in 2002. "Defense's Nuclear Agency, 1947-1997" traces the development of the Armed Forces Special Weapons Project (AFSWP), and its descendant government organizations, from its original founding in 1947 to 1997. After the disestablishment of the Manhattan Engineering District (MED) in 1947, AFSWP was formed to provide military training in nuclear weapons' operations. Over the years, its sequential descendant organizations have been the Defense Atomic Support Agency (DASA) from 1959 to 1971, the Defense Nuclear Agency (DNA) from 1971 to 1996, and the Defense Special Weapons Agency (DSWA) from 1996 to 1998. In 1998, DSWA, the On-Site Inspection Agency, the Defense Technology Security Administration, and selected elements of the Office of Secretary of Defense were combined to form the Defense Threat Reduction Agency (DTRA).

Book Synopsis Foundations of Qualitative Research by : Jerry W. Willis
Download or read book Foundations of Qualitative Research written by Jerry W. Willis and published by SAGE Publications. This book was released on 2007-01-26 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Willis catches the student up on relevant aspects of philosophy, empiricism, history, and prevailing political influences. This building of chronology is so valuable for students in understanding the origins of specific schools of thought in relations to a paradigm." —Heather T. Zeng, NACADA Foundations of Qualitative Research introduces key theoretical and epistemological concepts replete with historical and current real-world examples. Author Jerry W. Willis provides an invaluable resource to guide the critical and qualitative inquiry process written in an accessible and non-intimidating style that brings these otherwise difficult concepts to life. Key Features: Covers the conceptual foundations of interpretive, critical, and post-positivist paradigms: A thorough background of theory and social inquiry is given by looking at the development of each paradigm throughout history. Provides real-world examples: Cases illustrate different approaches to the same research problem so that students can better understand the contrasting features of these paradigms. Introduces seven qualitative research frameworks: In-depth coverage is provided on Altheide and Johnson′s Analytic Realism; Denzin and Lincoln′s Interpretive Perspective; Eisner′s Connoisseurship Model of Inquiry; Semiotics; the Phenomenological Psychological Model; Poststructuralism and Postmodernism; and Symbolic Interactionism. Offers general guidelines for qualitative research: Conceptually covers the best practices, approaches to data analysis, and interpretation of qualitative research. Examines emergent methods in qualitative research: New research areas such as PAR, emancipatory research, and participatory design research are included, as well as exemplary journal articles to further illustrate how theory links to research practice. Intended Audience: This text is designed for advanced undergraduate and graduate students taking their first or second qualitative research methods course in the fields of Education, Psychology, and the Health and Social Sciences. It is also an excellent theory companion supplement to the more applied qualitative methods text.
Book Synopsis Analysis of Cancer Risks in Populations Near Nuclear Facilities by : National Research Council
Download or read book Analysis of Cancer Risks in Populations Near Nuclear Facilities written by National Research Council and published by National Academies Press. This book was released on 2012-06-29 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late 1980s, the National Cancer Institute initiated an investigation of cancer risks in populations near 52 commercial nuclear power plants and 10 Department of Energy nuclear facilities (including research and nuclear weapons production facilities and one reprocessing plant) in the United States. The results of the NCI investigation were used a primary resource for communicating with the public about the cancer risks near the nuclear facilities. However, this study is now over 20 years old. The U.S. Nuclear Regulatory Commission requested that the National Academy of Sciences provide an updated assessment of cancer risks in populations near USNRC-licensed nuclear facilities that utilize or process uranium for the production of electricity. Analysis of Cancer Risks in Populations near Nuclear Facilities: Phase 1 focuses on identifying scientifically sound approaches for carrying out an assessment of cancer risks associated with living near a nuclear facility, judgments about the strengths and weaknesses of various statistical power, ability to assess potential confounding factors, possible biases, and required effort. The results from this Phase 1 study will be used to inform the design of cancer risk assessment, which will be carried out in Phase 2. This report is beneficial for the general public, communities near nuclear facilities, stakeholders, healthcare providers, policy makers, state and local officials, community leaders, and the media.

Book Synopsis The New Nuclear Forensics by : Vitaly Fedchenko
Download or read book The New Nuclear Forensics written by Vitaly Fedchenko and published by Oxford University Press. This book was released on 2015 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear material changes its form and properties as it moves through the nuclear fuel cycle, from one facility to another. Each step of the fuel cycle or each use of the material will inevitably leave its mark. The science of determining the history of a sample of nuclear material through the study of these characteristics is known as nuclear forensics. While nuclear forensic analysis has normally been associated with investigations and prosecutions in the contextof trafficking of nuclear materials or nuclear terrorism, it had wider applications in in national security contexts, such as nuclear non-proliferation, disarmament, and arms control. The New Nuclear Forensics is the first book to give a definitive guide to this broader definition of nuclear forensic analysis. This book describes the various methods used in nuclear forensics, giving first a broad introduction to the process followed by details of relevant measurement techniques and procedures. In each case, the advantages and limitations are outlined. To put these methods in context, the book also recounts the history of the discipline anddescribes the diverse contemporary applications of nuclear forensics.
