Hepatitis Delta Virus ; Vol. 307
Since its discovery nearly 30 years ago, hepatitis delta virus (HDV) has continued to surprise and fascinate. At 1,680 nucleotides the HDV genome is the smallest known to infect man. It is unique among animal viruses, the closest known relatives being plant viroids. To compensate for its limited protein coding capacity, HDV relies heavily on host functions and on structural features of its circular RNA genome. HDV infection depends on hepatitis B virus as a helper, and increases the severity of liver disease caused by HBV alone. There is currently neither an effective HDV vaccine nor a generally accepted useful therapy for HDV infection. This volume encompasses recent developments in HDV research, from molecular virology to genetics to experimental investigation of new therapeutic and vaccine candidates.
Handbook Utility Management
As the deregulation of European utility markets has progressed, the dynamics of and the competitive pressure in the utility industries have steadily intensified over recent years. These changes in the regulatory framework have caused a shift in the direction of an integrated market environment, resulting in new challenges for the management of power and gas companies and a substantial need for strategic reorientation. The Handbook Utility Management is concerned with these changes and challenges in the utility industries and emerging managerial issues of high practical relevance. Inclusion of the latest insights into the economic, technological, and legal drivers of the diverse value chain activities makes the Handbook a valuable asset for both professionals and researchers.
Groundwater overexploitation in the North China Plain : A path to sustainability
Over-pumping of aquifers is a worldwide problem, mainly caused by agricultural water use. Among its consequences are the falling dry of streams and wetlands, soil subsidence, die-off of phreatophytic vegetation, saline water intrusion, increased pumping cost and loss of storage needed for drought relief.
Glucose-6-phosphate dehydrogenase deficiency
Glucose-6-phosphate dehydrogenase deficiency, the most common enzyme deficiency worldwide, causes a spectrum of disease including neonatal hyperbilirubinemia, acute hemolysis, and chronic hemolysis. Persons with this condition also may be asymptomatic. This X-linked inherited disorder most commonly affects persons of African, Asian, Mediterranean, or MiddleEastern descent. Because acute hemolysis is caused by exposure to an oxidative stressor in the form of an infection, oxidative drug, or fava beans, treatment is geared toward avoidance of these and other stressors.
Global Change and the Earth System : A Planet Under Pressure
The interactions between environmental change and human societies have a long, complex history spanning many millennia, but these have changed fundamentally in the last century. Human activities are now so pervasive and profound that they are altering the Earth in ways which threaten the very life support system upon which humans depend. This book describes what is known about the Earth System and the impact of changes caused by humans. It considers the consequences of these changes with respect to the stability of the Earth System and the well-being of humankind; as well as exploring future paths towards Earth System science in support of global sustainability.
Geomatics Solutions for Disaster Management
Natural and anthropogenic disasters have caused a large number of victims and significant social and economic losses in the last few years. There is no doubt that the risk prevention and disaster management sector needs drastic measures and improvements in order to decrease damage and save lives of inhabitants. Effective utilization of satellite positioning, remote sensing, and GIS in disaster monitoring and management requires research and development in numerous areas: data collection, access and delivery, information extraction and analysis, management and their integration with other data sources (airborne and terrestrial imagery, GIS data, etc.), data standardization, organizational and legal aspects of sharing of remote sensing information. This book provides researchers and practitioners with a good overview of what is being developed in this topical area.

The series comprises seven volumes: Cereals and Millets; Oilseeds; Pulses, Sugar and Tuber Crops; Fruits and Nuts; Vegetables; Technical Crops; and Forest Trees. Fruits and nuts form the largest group among crop plants. Several constraints such as long life cycle, heterozygosity and large plant size caused comparatively slow research progress in the past. The chapters on 20 fruit and nut crops authored by 56 renowned scientists from 12 countries include for the first time comprehensive reviews on mango, banana, olive, pineapple, pistachio, persimmon and papaya. Other crops covered are apple, grape, cherry, plum, peach, pear, apricot, strawberry, raspberry, blueberry, almond, citrus and avocado.
Forensic pathology of trauma
The practice of forensic pathology includes the collection and analysis of evidence in relation to a corpse in order to establish the cause of death. Knowledge of the cause of death contributes to the determination of the manner of death by medical examiners and coroners, who are occasionally assisted by law enforcement officers. In the process of establishing the cause and manner of death, representatives of various investigative bodies have several responsibilities, including explaining the death to family members, attempting to reduce the risk of similar deaths in the future, and, if applicable, apprehending the individuals who are responsible for the death. The most well-known and popular role of a forensic pathologist is in the inves- gation of cases of suspicious death; however, most medicolegal autopsies involve unexpected deaths that are above suspicion, many of which are caused by trauma (trauma being defined as any physical force or agent that causes bodily harm). The purpose of Forensic Pathology of Trauma: Common Problems for the Pathologist is to provide practical advice and information about the conduct of the forensic autopsy in cases of trauma, and to offer guidance about the analysis of the autopsy findings in these cases.
Food-Borne Parasitic Zoonoses : Fish and Plant-Borne Parasites
The focus of this book is on those zoonoses that are transmitted by fish, plant and invertebrate foods. While people, especially those living in developed countries, are commonly aware of meat-borne zoonoses such as trichinellosis and cysticercosis, fewer are acquainted with parasitic diseases caused by liver, lung and intestinal flukes, fish-borne tapeworms, and tissue roundworms. This book reviews not only the prevalence and distribution of these zoonoses, including available health and economic impact data, but also highlights gaps in our knowledge base that must be filled in order to gain insights on approaches to prevention. The topics on epidemiology, diagnosis, and clinical aspects emphasize knowledge gaps that limit a full understanding of these zoonoses, and target where greater research investments on these parasitic diseases should be focused.
Food Safety and Ways to Prevent Life-Threatening Pollutants
The fears regarding food safety started long time ago, and till this very moment of ours, the international organizations and INGOs pay lots of hard work to minimize and achieve reduction in the effects and the suffering caused to people around the world by contaminated foods each year. This research talks about the main patterns of food contaminants, and they are chemical, physical, biological, and last but not least the contamination caused by radioactive substances. It is also important to talk about the methods of precaution and protection against the diseases and illnesses produced by contaminated foods, as well about the role of INGOs which are dedicated and specialized in law and regulations enactment for bounding the incidence of food contamination in the world, for raising the public awareness towards food safety, and to keep up with the latest updates of events. This research also contains vast Information about Covid-19 and its spreading process via contaminated food.
Flux Pinning in Superconductors
Covers the flux pinning mechanisms and properties and the electromagnetic phenomena caused by the flux pinning common for metallic, high-Tc and MgB2 superconductors.

Fluid Mechanics of Flow Metering
This book addresses two major fluid mechanical problems in flow metering: the analysis of signal generation in turbulent pipe flow, which explains the function of the meter beyond a simple calibration, and the possible use of a meter in non-developed flows. These problems are investigated with reference to, and examples from, a variety of meters, e.g. ultrasound cross-correlation meters, vortex meters, and turbine meters. Studying these problems requires consideration of specific phenomena in turbulent non-developed pipe flow, as caused by installations, and finding special solutions with signal processing, both of which are included in the book.

Environmental Risk Assessment : Quantitative Measures, Anthropogenic Influences, Human Impact
The world is a dirty place and getting dirtier all the time. The reasons for this ever-increasing lack of cleanliness are not hard to find, being basically caused by the actions of the six billion people who inhabit the planet. The needs of the people for air, water, food, housing, clothing, heating, materials, oil, gas, minerals, metals, chemicals, and so forth have, over the centuries, given rise to a variety of environmental problems that have been exacerbated or been newly created by the industrialization of the world, the increase in population, and the increase in longevity of the population. The costs of cleaning even fractions of the known environmental problems are truly enormous, as detailed in the volume Environmental Risk Analysis (I. Lerche and E. Paleologos, 2001, McGraw-Hill). The chances of causing new environmental problems, and their associated costs of clean up, are equally challenging in terms of anthropogenic influences and also of the natural environmental problems that can be triggered by humanity.
Environmental Problems of Central Asia and their Economic, Social and Security Impacts
entral Asia is a developing region with great potential, but there are valid concerns that current resource management practices are not sustainable, particularly with regard to the management of water resources. Recent changes in social structures, accompanied by regional climate change, have caused substantial environmental changes leading to security concerns in the region. As a result, the local economy has been significantly impacted to the extent that the potential for social unrest is of great concern.
