Download or read book Etude du ralentissement et de la localisation de la lumi re written by Naim Ben Ali and published by Noor Publishing. This book was released on 2017-03 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les Cristaux Photoniques (CPs) sont des structures dont l'indice dielectrique varie periodiquement ou quasi-periodiquement a l'echelle de la longueur d'onde dans une ou plusieurs directions de l'espace. La periodicite de l'indice dielectrique joue le meme role pour les photons que la periodicite du potentiel ionique dans un cristal pour les electrons. La periodicite peut etre unidimensionnelle, bidimensionnelle ou encore tridimensionnelle. De meme qu'il existe des bandes permises et des bandes interdites pour les electrons, il apparait des bandes interdites pour les photons dans les cristaux photoniques. Le ralentissement et la localisation de la lumiere dans ces cristaux permet d'accroitre le temps d'interaction entre la lumiere et le materiau et d'exalter des non-linearites optiques. Si on arrive a ralentir la lumiere suffisamment, on pourrait a terme developper des commutateurs et des routeurs tout-optique, qui traiteraient la repartition de l'information a une vitesse bien plus elevee que celle d'aujourd'hui. Notre travail est consacre a une etude du ralentissement et de la localisation de la lumiere dans des cristaux photoniques.

Available in PDF, EPUB and Kindle. Book excerpt: This thoroughly updated and extended edition covers the various cerebral visual disorders acquired after brain injury, as well as the rehabilitation techniques used to treat them. These are described within a brain plasticity framework, using data from single and group case studies along with follow up observation data. This original, tailor-made approach also includes the recording of eye movements for assessing scanning performance in scene perception and reading. The book gives a brief synopsis of the historical background on the subject, alongside an outline of intervention designs and methodological difficulties in the field, and goes on to discuss the mechanisms and processes that provide the foundations for recovery of function and successful adaptation in visually impaired patients. The author concludes by analyzing the importance of the procedures and outcomes of treatments to the reduction of patients’ visual handicaps. The new edition also contains an appendix with recommendations on the case histories, diagnostics and treatments. It is ideal reading for students in clinical neuropsychology, as well as professionals in the fields of neurology, visual neuroscience and rehabilitation experts.
Download or read book Large scale Mines and Local level Politics written by Colin Filer and published by ANU Press. This book was released on 2017-10-20 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the difference in their populations and political status, New Caledonia and Papua New Guinea have comparable levels of economic dependence on the extraction and export of mineral resources. For this reason, the costs and benefits of large-scale mining projects for indigenous communities has been a major political issue in both jurisdictions, and one that has come to be negotiated through multiple channels at different levels of political organisation. The ‘resource boom’ that took place in the early years of the current century has only served to intensify the political contests and conflicts that surround the distribution of social, economic and environmental costs and benefits between community members and other ‘stakeholders’ in the large-scale mining industry. However, the mutual isolation of Anglophone and Francophone scholars has formed a barrier to systematic comparison of the relationship between large-scale mines and local-level politics in Papua New Guinea and New Caledonia, despite their geographical proximity. This collection of essays represents an effort to overcome this barrier, but is also intended as a major contribution to the growth of academic and political debate about the social impact of the large-scale mining industry in Melanesia and beyond.
Download or read book Arctic Shipping written by Frédéric Lasserre and published by Routledge. This book was released on 2019-09-05 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book considers both the present state of Arctic shipping and possible future trends with reference to the various sectors of maritime transportation: cruise tourism, container traffic and bulk shipping. Ports are analysed as tools that support the strategies of coastal states to foster the development of resource extraction, enhance the attractiveness of Arctic shipping lanes and enable the control of maritime activities through coast guard deployment. The aim of this book is to draw a picture of the trends of Arctic shipping. How is traffic evolving in Canada’s Arctic, or along the Northern Sea Route? Are there significant differences between bulk and container shipping segments when considering the Arctic market? How are the ports and the hinterland developing and what are the strategies behind those? How is the legal framework shaping the evolution of maritime transportation? The contributors to this book consider all of these questions, and more, as they map out the prospects for Arctic shipping and analyse in detail the development of Arctic shipping as a result of multi-variable interactions. This book will be key reading for industry professionals and post-graduate students alike.

Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
Download or read book Handbook of Psychiatry in Palliative Medicine written by Harvey Max Chochinov and published by . This book was released on 2009 with total page 591 pages. Available in PDF, EPUB and Kindle. Book excerpt: Psychiatric, or psychosocial, palliative care has transformed palliative medicine. Palliation that neglects psychosocial dimensions of patient and family experience fails to meet contemporary standards of comprehensive palliative care. While a focus on somatic issues has sometimes overshadowed attention to psychological, existential, and spiritual end-of-life challenges, the past decade has seen an all encompassing, multi-disciplinary approach to care for the dying take hold. Written by internationally known psychiatry and palliative care experts, the Handbook of Psychiatry in Palliative Medicine is an essential reference for all providers of palliative care, including psychiatrists, psychologists, mental health counselors, oncologists, hospice workers, and social workers.
Download or read book Biology of the Arterial Wall written by Bernard I. Levy and published by Springer Science & Business Media. This book was released on 2007-11-23 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biology of the Arterial Wall is intended as a general reference text concerned with the biology of the vascular cells and the blood vessel wall under physiological and pathological conditions. One of the major functions of the arteries is to maintain a continuous blood flow to the organs whatever the pressure conditions, thanks to the vasomotor tone of the smooth muscle cells. Great advances have been made over the last decade in the understanding of the endothelial cells as integrators and transducers of signals originating from the blood stream. The pluripotent control functions of the endothelial cells in the vessel wall are now well recognized. A review of endothelial functions and dysfunctions is presented. Cell biology and molecular genetic studies have now identified an array of molecules elaborated by endothelial cells and vascular smooth muscle cells and by the blood-borne elements which interact with artery cells, defending the artery against injury and modulating evolving abnormal processes. Molecules which induce or inhibit endothelial and/or smooth muscle cells are currently under great scrutiny. Angiogenesis, which plays a major role in tumor growth, but may also be beneficial as a healing process in muscle ischemia, is discussed. Apoptosis, or programmed cell death, has only recently been recognized as an essential process in blood vessel modeling and remodeling. An overview of apoptosis in the vascular system is presented. It is increasingly evident that the adjustments of the blood vessel wall are made in the presence of deforming disease processes such as hypertension and atherosclerosis. The second part of the book is concerned with the blood vessel wall in disease conditions. Several chapters review the role of the vessel and vascular cells in inflammation, and vascular remodeling during arterial hypertension and aging. One chapter is devoted to atherogenesis, atheroma and plaque instability, followed by the pathophysiology of post-angioplasty restenosis, which is a crucial issue in modern interventional cardiology.

Download or read book The Uncertain Quest written by Francisco R. Sagasti and published by . This book was released on 1994 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Science - "empirical knowledge" - and technology - "applied science" - have long played a key role in social development. In modern times they have come to be seen as absolutely essential factors in the achievement of economic growth and development. And though many dispute their ascendancy and legitimately point to their abuses, there is no escaping their presence and impact." "Taking as a main theme the central role of science and technology in economic progress, this first-of-a-kind sourcebook gathers together the perspectives and expertise of an international body of specialists in science and technology policy to examine the role of science and technology in development, and assess their social, economic, and political dimensions. The authors look at the key issues in relation to the exigencies of developing countries in the "new international context." They emphasize the complexity of the links between science, technology, and development and the important insights to be gained from the study of these links. The authors also point out that, despite science and technology's promise of social and economic progress, such progress is less than ever an inevitable result of their application - though there is no doubt about what can be achieved through science and technology, the quest is an uncertain one."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
