Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book provides information on the incidence of fungi and mycotoxins in some African countries, the health implications and possible intervention control strategies for mycotoxins in developing countries and in Africa in particular. It will therefore be of interest to students, educators, researchers and policy makers in the fields of medicine, agriculture, food science and technology, trade and economics. Food regulatory officers also have quite a lot to learn from the book. Although a lot of the generated data in the area of mycotoxicology are available to the developed world, information on the subject area from Africa is scanty and not usually available in a comprehensive form. This book attempts to address the gap. Being an open access book, it will be of great benefit to scientists in developing countries who have limited access to information due to lack of funds to pay or subscribe for high quality journals and data from commercial publishing and database companies. 282 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Diesel engines, also known as CI engines, possess a wide field of applications as energy converters because of their higher efficiency. However, diesel engines are a major source of NOX and particulate matter (PM) emissions. Because of its importance, five chapters in this book have been devoted to the formulation and control of these pollutants. The world is currently experiencing an oil crisis. Gaseous fuels like natural gas, pure hydrogen gas, biomass-based and coke-based syngas can be considered as alternative fuels for diesel engines. Their combustion and exhaust emissions characteristics are described in this book. Reliable early detection of malfunction and failure of any parts in diesel engines can save the engine from failing completely and save high repair cost. Tools are discussed in this book to detect common failure modes of diesel engine that can detect early signs of failure. 280 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Neonatal sepsis still remains a significant cause of morbidity and mortality in the newborn, particularly in preterm, low birth weight infants. Despite advances in neonatal care, overall case-fatality rates from sepsis may be as high as 50%. Clinical signs of bacterial infection are vague and non-specific, and up to now there exists no easily available, reliable marker of infection despite a large bulk of studies focussing on inflammatory indices in neonatology. Every neonatologist is faced with the uncertainty of under- or over- diagnosing bacterial infection. In this book three topics will be discussed: clinical presentation including a general approach to sepsis neonatorum and two distinct diagnoses pneumonia and osteomyelitis diagnostic approaches including C-reactive protein and the immature myeloid information, and prevention and treatment of bacterial infection with immunoglobulins. 106 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book summarizes several aspects of GD, which is caused by not well-understood multifactorial mechanisms. Common strategies seem to be key in the understanding of the syndrome, i.e., endothelial dysfunction and the role of other placenta cells such as trophoblasts. It is a book that will definitively help to increase the knowledge-based management of GD for the well being of the mother and the fetus. Several chapters lead us to the conclusion that pre-pregnancy and antenatal screening of women is required, something that will improve the management and outcome of a current pregnancy but will also optimize life-long health and well being considering the inter-generational consequences. 174 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -By virtue of the dynamic nature of the scientific process, the description of the type, pathogenesis and treatment of a disease is always a work in progress.

For better development of this book, the main objective was to provide insights on the types, causes, and treatments of psoriasis. This approach might substantially improve the transference of disease knowledge for physicians and intended to improve quality of medical services that endorses training of excellence and assesses the quali cations of physicians, most of whom will be naive to clinical dermatological practices. 192 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Shape memory alloys have become in the past decades a well established research subject. However, the complex relations between properties and structure have created a continuously growing interest for a deeper insight all this time. The complexity of relationships between structure and properties is mostly related to the fact that strong multidimensional interactions are taking place: from the early studies focusing on the thermal and/or mechanical induced phase transformations to the more recent findings on the magnetically induced structural changes. On the other hand, these singular behavioral characteristics have driven a great industrial interest due to the innovative aspects that the applications of shape memory alloys may provide. This makes this subject a highly attractive source of continuous studies, ranging from basics crystallography and thermodynamics to mechanical analysis and electrical and magnetic properties characterization.In this book, a group of recent studies is compiled focusing on a wide range of topics from processing to the relationship between the structure and properties, as well as new applications. 292 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book describes different perspectives of childhood acute lymphoblastic leukemia. The approach includes aspects of molecular epidemiology, particularly molecular features that influence the genesis and prognosis of the disease. Some aspects of the prognosis of lymphoblastic leukemias are very detailed, highlighting the use of molecular biology in the early identification of complications that may occur in diseased patients. The authors of the present book conform a Mexican group who identifies the causes of leukemia, and they summarize their experience in research, results and proposals for future studies. A causal model is included in which the authors hypothesized the origin of acute lymphoblastic leukemias, particularly in children. This hypothesis can be useful to better understand other cancers during childhood.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Twenty years after the discovery of neural stem cells, the question whether the central nervous system can be considered among regenerative tissues is still open. On one side, deep characterization of neural stem and progenitor cells, their niches, and their progeny in brain neurogenic sites overtly showed that new neurons can be generated in the brain of adult mammals, including humans. On the other side, many problems arise when stem cells encounter the mature brain parenchyma, still hampering the development of efficacious therapeutic approaches with endogenous or exogenously-delivered neural stem cells. This book tries to make the point on these extremely promising, yet unresolved, issues. 430 pp. Englisch.
