Book Description
Discovery and Relative Importance of Continuous Arteriovenous HemofIltration Lee W. Henderson Continuous arteriovenous hemofiltration (CAVH) has seen a brisk upswing in popularity in Europe since its introduction by Dr. Kramer and colleagues from Gottingen, West Germany in 1977 [1]. In the United States, the technique re ceived approval as a clinical tool from the Food and Drug Administration in April 1982. This approval flowed, in no small measure, from the extensive expe rience reported from Europe and in particular West Germany [e. g., 2, 3]. Reports of its clinical utility now have begun to appear in the United States [4]. Removal of excess total body water using synthetic membranes in an extracor poreal circuit dates back to the work of Alwall and the artificial kidney that he designed which permitted utilization of a hydrostatic pressure gradient to moti vate water flow across the membrane [5]. Kolffs original rotating drum with its unencased membrane required an osmotic driving force [6]. Hemofiltration, the use of the filtration process to remove uremic solutes with the artificial kidney, in analogy with the glomerulus, was reported in 1967 [7]. This was made possible by the availability of synthetic membranes with far higher hydraulic permeability (approximately 10 times higher) than conventionally used cellulosic hemodialysis membrane. Specific applications of these "high flux" membranes to the removal primarily of excess total body water followed shortly thereafter [8].

Book Description
This multidisciplinary book presents a critical assessment of our knowledge of chemical threats to environmental security, with special reference to prevention of chemical releases, rapid detection, risk assessment and effective management of emergency situations and long-term consequences of chemical releases. The technologies evaluated concern mainly prevention and management of both intentional and accident releases of chemicals into the environment. The book features contributors from a range of relevant scientific fields.

Book Description
Determination of Metals and Anions in Soils, Sediments and Sludges is the first volume which comprehensively discusses the range of methods currently available for the analysis of metals and anions in soils, river and marine sediments and industrial sludges. There are specialist chapters on sampling, pollutant accumulation in sediments and bioaccumulation from soils to crops. A particular feature of this volume is its coverage of solid sewage, which is increasingly being applied to land as a fertilizer. An essential reference for chemists and toxicologists involved in water resource management, agrochemistry, fisheries and public health.

Book Description
This is the second edition of this publication which focuses on the public health aspects of the possible deliberate use of biological or chemical agents. Issues discussed include: the key principles for public health planning, risk assessment, hazard identification and evaluation, risk management strategies, and response planning as part of existing national emergency plans, disease surveillance and early warning systems, the national and international legal framework, and international sources of assistance. Technical annexes cover a range of issues including chemical agents, toxins, biological agents, principles of protection, precautions against the sabotage of drinking water, food and other products, information resources and the affiliation of WHO Member States to the international treaties on biological and chemical weapons.

Book Description
Expanded second edition retains essential sampling theory and technology from the popular first edition, but adds 24 new chapters to cover the most recent sampling technology for all major environmental matrices: water, air, biota, solids, sludges, and liquid wastes. Focuses on the essentials of obtaining reliable samples, including calculating how many samples to collect for specific objectives and confidence levels. Presents typical problems and solutions, sampling equipment, preservation techniques, and special considerations for each matrix. This new edition is useful for both experts and novices who need to obtain reliable environmental samples.

Book Description
Low-molecular-weight (LMW) heparins are increasingly used in the prevention and treatment of thromboembolic disease because, compared to unfractionated heparins, they show a higher benefit/risk ratio and better clinical convenience. This special issue reports the proceedings of a symposium which reviewed all the available data on the properties of these agents and their therapeutic applications. Several contributions present studies on the use of LMW heparins in the prophylaxis of venous thromboembolism after surgery and in nonsurgical situations, as well as in the treatment of established venous thrombosis. Arterial thrombosis as another potential indication for LMW heparins is discussed. Authoritative and up-to-date, this publication is essential reading for anyone dealing with thromboembolic disease from a pharmacological or a clinical point of view.

Book Description
The management of critically ill patients is rapidly undergoing change as new technology for the diagnosis, monitoring and treatment of these patients is being utilized. Moreover, the understanding of the pathophysiology of multi-organ failure has greatly increased, a key element in its management involving the support of organ function to allow specific interventions or time for recovery. Originally introduced as an alternative for intermittent hemodialysis, CRRT techniques are now also used for renal support not only in the traditional setting of acute renal failure, but also in other settings as diverse as liver support systems for end-stage liver disease and cancer chemotherapy. This utilization of a common mechanism of blood and plasma membrane interactions is truly an exciting advance, which is likely to be further developed in the next decade. In this multidisciplinary publication, recent advances in our understanding of pathophysiology and critical illness are highlighted, as well as emerging strategies in the management of sepsis, liver failure, acute renal failure, technical advances in CRRT and targeted intervention with these techniques. Since this publication provides articles relevant to the management of critically ill patients requiring renal support in the ICU setting, it should be read not only by nephrologists and critical care physicians, but by all those involved in the care of patients with multi-organ failure.

Book Description
Acknowledging the importance of non traditional security in the wider debate, this book looks at one significant aspect namely, environmental security. The book discusses different issues of theoretical and practical import through various chapters that deal with the general need for study on human and environmental security, its degradation due to a variety of factors like climate change, war, pollution and resource utilisation. Moving from a regional South Asian focus the book narrows down to specific cases within India and the region at large to highlight the widespread effect anthropogenic factors have had on environmental security. A diverse set of articles from many authors has meant a comprehensive perspective on a vital global and national concern.
