This book was released on 2002 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents a study of changes in electron transfer processes between atomic particles and Ag(111), Ag(110) and Ag(100) surfaces exposed to chlorine. The general motivation of our study is the analyse of electronic effects in the promotion and poisoning of reactions on surfaces. Results of a study of changes in electron capture and loss rates in the interaction of fluorine, hydrogen and oxygen atoms and anions are reports for a wide range of coverages. A strong decrease is observed in the F ̄formation rates at low coverage in chemisorptions conditions on the chlorine-covered Ag(111), Ag(110) and Ag(100). The observed decrease is assigned to changes in local electronic structure at and in the vicinity of the adsorbate site and modifications in positions and widths of the anion levels. At high coverages a higher electron-capture probability is found on Ag(III), corresponding to the appearance of chlode islands. In the case of H ̄and O ̄the capture and loss rates are reported for chlorine surface Ag(111). Strong oscillatory changes in anion formation rates are observes as a function of chlorine coverage. These changes are discussed in terms of changes in local electronic structure and modifications in positions and widths of the anion levels at different phases of chlorine adsorption and in particular to interaction of the projectile with the adsorbed Cl(3p) levels. At high coverages, a higher electron capture is found, corresponding to the formation of the cristal AgCl on Ag(111). The effect of chemical environment on the neutralisation of ions with adsorbate covered surfaces was investigated in the case of H+, Ar+, Ne+ ans He+ scattered on the three surfaces exposed to chlorine. Changes in coverage in the submonolayer region of chlorine adsorption induce an non-linear oscillation of electron transfer probabilities for H+. Ar+, Ne+. This can be relates to changes in the electronic structure due to the presence of the chlorine levels. With increasing chlorine adsorption the fractions obtained on Ag(111) are affected by the appearance of chloride island on Ag(111). In the case of more highly bound He, we assigned the observed changes to modifications in quasi-resonant charge transfer rates involving the Cl(3s) level.
Download or read book Comprehensive Cervical Cancer Control written by World Health Organization and published by World Health Organization. This book was released on 2006 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most women who die from cervical cancer, particularly in developing countries, are in the prime of their life. They may be raising children, caring for their family, and contributing to the social and economic life of their town or village. Their death is both a personal tragedy, and a sad and unnecessary loss to their family and their community. Unnecessary, because there is compelling evidence, as this Guide makes clear, that cervical cancer is one of the most preventable and treatable forms of cancer, as long as it is detected early and managed effectively. Unfortunately, the majority of women in developing countries still do not have access to cervical cancer prevention programmes. The consequence is that, often, cervical cancer is not detected until it is too late to be cured. An urgent effort is required if this situation is to be corrected. This Guide is intended to help those responsible for providing services aimed at reducing the burden posed by cervical cancer for women, communities and health systems. It focuses on the knowledge and skills needed by health care providers, at different levels of care.
Download or read book Microdosimetry written by Lennart Lindborg and published by CRC Press. This book was released on 2020-10-02 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental microdosimetry deals with the measurement of charged particle energy deposition in tissue equivalent volumes, ranging in size from nanometres to micrometres. Microdosimetry is employed to improve our understanding of the relationship between radiation energy deposition, the resulting biological effects, and the appropriate quantities to be used in characterizing and quantifying radiation quality. Although many reviews and contributions to the field have been published over the past fifty years, this new book is the first to provide a single, up to date, and easily accessible account of experimental microdosimetry. This book is designed to be used in medical, radiation, and health physics courses and by Master's and PhD students. In addition to serving as an introductory text to the field for graduate students, this book will also be of interest as a teaching and reference resource for graduate supervisors and established researchers. Drs. Lennart Lindborg and Anthony Waker have spent a life-time career in experimental microdosimetry research in academic, industrial and regulatory environments and have observed the development of the field from its early days as a recognized discipline; they bring to this book particular knowledge and experience in the design, construction, operation and use of tissue equivalent gas ionization counters and chambers.
Download or read book On the Death and Life of Languages written by Claude Hagège and published by Yale University Press. This book was released on 2009-01-01 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty-five languages die each year; at this pace, half the world’s five thousand languages will disappear within the next century. In this timely book, Claude Hagège seeks to make clear the magnitude of the cultural loss represented by the crisis of language death. By focusing on the relationship of language to culture and the world of ideas, Hagège shows how languages are themselves crucial repositories of culture; the traditions, proverbs, and knowledge of our ancestors reside in the language we use. His wide-ranging examination covers all continents and language families to uncover not only how languages die, but also how they can be revitalized—for example in the remarkable case of Hebrew. In a striking metaphor, Hagège likens languages to bonfires of social behavior that leave behind sparks even after they die; from these sparks languages can be rekindled and made to live again.

Download or read book Cancer Pain Relief written by World Health Organization and published by World Health Organization. This book was released on 1996 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of a guide, which introduced a simple, yet highly effective method for the relief of cancer pain. Thoroughly revised and updated, the new edition further refines the WHO method, which advocates the use of a small number of relatively inexpensive drugs, including morphine. Revisions draw on experiences with millions of patients around the world as well as new knowledge about the specific pain syndromes unique to cancer. Completely new are chapters describing the international system by which morphine and other opioids are made available for medical purposes. The book has two parts. Part one provides a practical guide to the relief of cancer pain, concentrating on drug treatment as the mainstay of pain management. The most extensive section sets out detailed guidelines for the selection and prescribing of non-opioid analgesics, opioid analgesics, drugs for neuropathic pain, and adjuvant drugs for the treatment of adverse effects, the enhancement of pain relief and the management of concomitant psychological disturbances. Information ranges from explanations of how specific drugs work, through the precautions to take in the presence of certain disorders, to a list of factors that influence the effectiveness of opioids. Concerning the use of opioids, readers are reminded that psychological dependence does not occur in cancer patients and that the only correct dose of morphine is the one that relieves the pain. Part two provides a guide to opioid availability. A discussion of the reasons why opioids continue to be underprescribed or difficult to obtain is followed by an explanation of the Single Convention on Narcotic Drugs.

Download or read book World Health Organization Guidelines on the Pharmacological Treatment of Persisting Pain in Children with Medical Illnesses written by World Health Organization and published by . This book was released on 2012 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: These guidelines have been developed to support countries to relieve pain in their paediatric populations. These guidelines address persisting pain in children caused by conditions such as cancer, HIV/AIDS, sickle-cell disease, burns, trauma, and phantom limb pain. Recommendations -- developed following a careful and transparent appraisal of available evidence -- are presented for the pharmacological treatment of mild, moderate and severe pain. The guidelines include chapters on the various systems used to classify pain and on the evaluation of pain, which reviews the available tools for routine pain measurement in children. Provision of sustainable pain relief within health care systems is covered in a separate chapter. Since morphine and other opioid analgesics -- required for the relief of moderate-to-severe pain in children -- are listed under the 1961 UN Single Convention on Narcotic Drugs, the new guidelines include an annex explaining the Convention's requirements for the handling and procurement of opioid analgesics for the relief of pain.
