The Sixth International Workshop on Persistent Object Systems was held at Les Mazets des Roches near Tarascon, Provence in southern France from the fifth to the ninth of September 1994. The attractive context and autumn warmth greeted the 53 participants from 12 countries spread over five continents. Persistent object systems continue to grow in importance. Almost all significant uses of computers to support human endeavours depend on long-lived and large-scale systems. As expectations and ambitions rise so the sophistication of the systems we attempt to build also rises. The quality and integrity of the systems and their feasibility for supporting large groups of co-operating people depends on their technical founda tion. Persistent object systems are being developed which provide a more robust and yet simpler foundation for these persistent applications. The workshop followed the tradition of the previous workshops in the series, focusing on the design, implementation and use of persistent object systems in particular and persistent systems in general. There were clear signs that this line of research is maturing, as engineering issues were discussed with the aid of evidence from operational systems. The work presented covered the complete range of database facilities: transactions, concurrency, distribution, integrity and schema modifica tion. There were examples of very large scale use, one involving tens of terabytes of data. Language issues, particularly the provision of reflection, continued to be important.

Environmental pollution by man-made persistent organic chemicals (POCs) has been a serious global issue for over half a century. POCs are prevalent in air, water, soil, and organisms including wildlife and humans throughout the world. They do not degrade and cause long-term effect in organisms. Exposure to certain POCs may result in serious environmental and health effects including birth defects, diminished intelligence and certain types of cancers. Therefore, POCs have been the subject of an intensive regional, national and international effort to limit their production, use, and disposal of these chemical stocks. Trend monitoring studies are essential to make clear the behavior and fate of these compounds and to protect our environment and living resources. Global Contamination Trends of Persistent Organic Chemicals provides comprehensive coverage of spatial and temporal trends of classical and emerging contaminants in aquatic, terrestrial, and marine ecosystems, including the Arctic and Antarctic ecosystems. Compiled by an international group of experts, this volume covers: Spatial and temporal trends of polychlorinated biphenyls (PCBs), chlorinated pesticides, polychlorinated naphthalenes (PCNs), polychlorinated dibenzo-p-dioxins/furans (PCDD/DFs), polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes (HBCDs), perfluorinated compounds (PFCs), synthetic musks, polynuclear aromatic hydrocarbons (PAHs), and octyl- and nonylphenols Environmental and biological matrices used for the trend studies were atmosphere, water, soil, sediment, bivalve mollusks, fish, marine mammals, terrestrial mammals, and human breast milk Spatial and temporal trend studies presented from Australia, Brazil, China, Estonia, Ghana, Hong Kong, India, Italy, Japan, Korea, Norway, Poland, Sweden, the United States, coastal and open ocean environments, and the Arctic and Antarctic regions POCs have been the subject of an intensive regional, national, and international effort to limit their production and use, and to mitigate the disposal of these chemicals. Since POCs are prevalent in air, water, soil, and tissues of organisms (including wildlife and humans) throughout the world and do not degrade, they cause long-term effects in organisms. Trend monitoring studies are essential to make clear the behavior and fate of these compounds and to protect our environment and living resources. Relevant to professionals and students alike, Global Contamination Trends of Persistent Organic Chemicals facilitates the understanding of environmental and biological behavior of these chemicals and the development of strategies for protecting the global environment for future generations.

Free Download The Fate of Persistent Organic Pollutants in the North Sea: Multiple Year Model Simulations of γ-HCH, α-HCH and PCB 153 By Dr. Tatjana P. Ilyina (auth.)

Persistent organic pollutants (POPs) are harmful to human health and to the environment. Their fate in the marine environment is not yet fully understood. An ocean model (FANTOM) has been developed to investigate the fate of selected POPs in the North Sea. The main focus of the model is on quantifying the distribution of POPs and their aquatic pathways. This is the first time that a spatially-resolved, measurement-based ocean transport model has been used to study POP-like substances, at least on the regional scale. The model was applied for the southern North Sea and tested by studying the behaviour of g-HCH, a-HCH and PCB 153 in sea water. This model study proves that transport models, such as FANTOM, are capable of reproducing realistic multi-year temporal and spatial trends of selected POPs and can be used to address further scientific questions.

Free Download Sean F. McMahon, "The Discourse of Palestinian-Israeli Relations: Persistent Analytics and Practices"
English | 2013 | ISBN: 041585363X | EPUB | pages: 242 | 0.3 mb
Many observers have portrayed the Oslo Process as a milestone in the peacemaking process between Palestinians and Israelis. In this controversial and groundbreaking new work, McMahon challenges the interpretation of the Oslo Process as a breakthrough or new beginning in Palestinian-Israeli relations. He argues that the Oslo Process affected no discursive or non-discursive change and that the Oslo Process in fact institutionalized the analytics practices involved in Israeli and Palestinian relations. It should, McMahon concludes, be no surprise that the process ended with direct Palestinian-Israeli violence. This book will be crucial reading for scholars of Israeli and Palestinian relations as well as anyone who is interested in understanding what discursive change must occur for peace between Israel and Palestinians to be established and sustained.

Free Download Persistent Luminescence: Fundamentals, Mechanisms and Applications
English | 2024 | ISBN: 9819749425 | 407 Pages | PDF EPUB (True) | 102 MB
This book presents the fundamental and applied properties of different phosphor materials that exhibit the phenomenon of persistent luminescence (PerLum). PerLum offers a solution for the limitations of existing fluorescent probes, with new lanthanide-based materials for in vivo bio-imaging and demonstrates the practical applications of these materials. The book offers a basic understanding of PerLum, different mechanisms, models, related spectroscopic techniques, and a few applications essential for anyone interested in learning about PerLum materials. This is partly due to the fact that the property of long-lasting luminescence is closely associated with other properties and functionalities, which besides being essential for many technological applications, such as bioimaging and biosensing, involve in-depth physics and chemistry. Although the concept of luminescence has been explored for many decades, the different types of luminescence have always led to versatile breakthroughs in different fields of science and technology. Among the same is one more well-established phenomenon known as "PerLum," which is characterized by the maintenance of luminescence for periods ranging from minutes to hours in the absence of an external excitation source. Because of their remarkable properties, an enormous number of PerLum materials have been developed and are now widely used in a variety of fields, particularly bioimaging, biosensing, therapeutics, etc.
