Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Today, satellite navigation offers convenient alternative to terrestrial and stellar navigation methods that is not only ubiquitous and easy to operate but also available day and night. The radio navigation technology, first appeared in the 1930s and matured in the 1940s, did not take off until the late 1960s and 1970s with the launch of the first navigation satellites by the US Naval and Air Forces, resulting from the NAVSTAR GPS program. The end user navigation equipment, bulky and expensive at the beginning, did not emerge until the microprocessor became viable during the late 1970s. Now-a-day three other global navigation satellite systems are fully or partially operational: the Russian GLONASS, the European Union Galileo, and the Chinese BeiDou. Where does the future lie Probably in a network of global satellite navigation systems, with increase in satellite coverage and improved accuracy, integrity, and reliability, as these systems further mature. End user equipment will continue to be smaller, more accurate and cheaper. Yet in many respects, satellite navigation systems owe most to the old-time stellar navigation, by keeping man look up to the sky for help. 170 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Amyloidosis is an uncommon disorder characterized by the deposition of extracellular amyloid proteins in tissues. Significant advancement has been made recently, which not only provides insight in to the pathophysiology of the disease but also helps to discover new therapies to fight the deadly disease. If accurate diagnosis and typing are made early, effective or even curative therapies are available. Unfortunately, because of the rarity of the disease and its protean clinical manifestations, patients may be misdiagnosed, especially at early stage of the disease, and this could lead to missed opportunities to effective therapy. The aim of the book is to help readers become familiar with the clinical presentation of amyloidosis and to review the latest diagnostic and therapeutic development. 250 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -There has been a remarkable difference in the research and development regarding gas turbine technology for transportation and power generation. The former remains substantially florid and unaltered with respect to the past as the superiority of air-breathing engines compared to other technologies is by far immense. On the other hand, the world of gas turbines (GTs) for power generation is indeed characterized by completely different scenarios in so far as new challenges are coming up in the latest energy trends, where both a reduction in the use of carbon-based fuels and the raising up of renewables are becoming more and more important factors. While being considered a key technology for base-load operations for many years, modern stationary gas turbines are in fact facing the challenge to balance electricity from variable renewables with that from flexible conventional power plants. The book intends in fact to provide an updated picture as well as a perspective view of some of the abovementioned issues that characterize GT technology in the two different applications: aircraft propulsion and stationary power generation. Therefore, the target audience for it involves design, analyst, materials and maintenance engineers. Also manufacturers, researchers and scientists will benefit from the timely and accurate information provided in this volume. The book is organized into three main sections including 10 chapters overall: (i) Gas Turbine and Component Performance, (ii) Gas Turbine Combustion and (iii) Fault Detection in Systems and Materials. 270 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In June 2001, operators and equipment vendors in the communications ecosystem founded the nonprofit WiMAX Forum, an industry-led organization aimed at harmonizing broadband wireless access standards.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Endocarditis is an inflammation of the lining of the heart and valves. It can be due to a non-infectious cause but when the inflammation is associated with an infection, usually bacterial, it is known as infective endocarditis. It is typically characterized by the development of a large septic thrombus on one of the cardiac valves. As this thrombus grows, it can lead to valve failure or may fragment forming a septic embolus that is associated with high mortality if the target of the embolus is the brain, heart or lung. This book reviews multi-organ complications associated with Infective endocarditis including significant recent advances in molecular mechanisms underlying thrombus formation on the cardiac valve, anti-microbial treatment and surgery. 134 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book summarizes the advances and new concepts introduced in the last years on peritoneal dialysis (PD) and its complications. PD therapy is a renal replacement peritoneal membrane using a semi-permeable barrier to liquids and solutes. The abdominal cavity with all its components, mesothelial cells, fat tissue, immune system components and others are activated by the PD fluids that although every time are more biocompatible, induce production of molecules with the local and systemic effects. Locally there is a thickening of the peritoneal membrane leading to the failure of this and where the transdifferentiation of mesothelial cells plays a key role. Systemically activating abdominal cavity appears to be involved in atherosclerosis, diabetes, hypertension, renal bone disease pathway and others. 116 pp. Englisch.
