Buch. Zustand: Neu. Neuware -Neurodegenerative diseases are debilitating conditions that result in degeneration and death of nerve cells. A significant group of these diseases is the synucleinopathies, which are characterized by the accumulation of aggregates of alpha-synuclein in neurons, nerve fibers, or glial cells. There are three main types of synucleinopathies: Parkinson's disease, dementia with Lewy bodies, and multiple system atrophy. Synucleins are small, naturally unfolded proteins prone to aggregate and form intracellular inclusions, which impair normal cellular functions. This book presents new data on synuclein aggregation and its effect on cholesterol transport. It also discusses the role of genetic contribution to these diseases and approaches to inhibition of synuclein aggregation.Books on Demand GmbH, Überseering 33, 22297 Hamburg 96 pp. Englisch.

Buch. Zustand: Neu. Neuware -Fault detection, control, and forecasting have a vital role in renewable energy systems (Photovoltaics (PV) and wind turbines (WTs)) to improve their productivity, ef ciency, and safety, and to avoid expensive maintenance. For instance, the main crucial and challenging issue in solar and wind energy production is the volatility of intermittent power generation due mainly to weather conditions. This fact usually limits the integration of PV systems and WTs into the power grid. Hence, accurately forecasting power generation in PV and WTs is of great importance for daily/hourly efficient management of power grid production, delivery, and storage, as well as for decision-making on the energy market. Also, accurate and prompt fault detection and diagnosis strategies are required to improve efficiencies of renewable energy systems, avoid the high cost of maintenance, and reduce risks of fire hazards, which could affect both personnel and installed equipment. This book intends to provide the reader with advanced statistical modeling, forecasting, and fault detection techniques in renewable energy systems.Books on Demand GmbH, Überseering 33, 22297 Hamburg 210 pp. Englisch.

Buch. Zustand: Neu. Neuware -The relationship between herpesviruses and humans probably dates from thousands of years ago. In the last few decades, many aspects of herpesvirus infections have been understood, such as infections with a range of manifestations (severe, mild, or subclinical). Herpesvirus can remain latent during a lifetime and sometimes their reactivation can cause different clinical features in the patient. Several conditions have been related to herpesvirus reactivation such as complications in transplant organ recipients and immune regulatory modification in the elderly. Aspects of human herpesvirus simples, varicella-zoster virus, and cytomegalovirus are presented and discussed in this book.Books on Demand GmbH, Überseering 33, 22297 Hamburg 128 pp. Englisch.

Buch. Zustand: Neu. Neuware -Biological nitrogen fixation (BNF), the process by which gaseous N2 is converted into ammonia (NH3) via the enzyme nitrogenase, is crucial for the availability of nitrogen (N) in the terrestrial ecosystem. Some bacteria have the remarkable capacity to fix atmospheric nitrogen to ammonia under ambient conditions, a reaction only mimicked on an industrial scale by a chemical process. This microbiological process converts atmospheric nitrogen into a plant-usable form, thus decreasing the need to use chemical fertilizers in crop production. Chapters in this volume cover different aspects of this fantastic phenomenon, including biofertilizer, organic nitrogen in agricultural systems, nitrogen fertilization for sustainable crop production, and others. This book is designed for researchers, students and general readers.Books on Demand GmbH, Überseering 33, 22297 Hamburg 202 pp. Englisch.

Buch. Zustand: Neu. Neuware -Plant pathogens, the causal agent of infectious plant diseases, influence our lives more than just as an economic impact through yield lost. The study of plant pathogens has given rise to the development of new sciences, new technologies for plant breeding, and the agrochemical industry for pesticide developments. Yet, all our actions and efforts to suppress or eradicate them constantly pressures these various organisms to evolve and adapt for survival. Therefore today, when facing climate changes, accelerated transport of plants and plant products, and world population growth, we have to ask quo vadis phytopathology. Like Alice in Wonderland ¿If we wish to go anywhere we must run twice as fast as that¿ so we need to constantly broaden our knowledge. However, today¿s literature abounds with knowledge about plant pathogens. Hence, this book intends to present to the reader all the latest material and knowledge about plant pathogens, changes or refinements in plant disease epidemiology, and new approaches and materials used for plant pathogen control. Hopefully, this book will be of interest to those working within the field and looking for an up-to-date introduction. We hope it also interests students and thereby, will influence the future development of phytopathology and our better coexistence with plant pathogens.Books on Demand GmbH, Überseering 33, 22297 Hamburg 240 pp. Englisch.

Buch. Zustand: Neu. Neuware -Inhibitory control is a critical neurocognitive skill for navigating cognitive, social, and emotional challenges. It rapidly increases during the preschool period and is important for early cognitive development, as it is a crucial component of executive functioning, self-regulation, and impulsivity. Inhibitory control training (ICT) is a novel intervention in which participants learn to associate appetitive cues with inhibition of behavior. It is being considered a promising approach in the treatment of psychopathology and appetitive behaviors. This book aims to bring together knowledge on the topic, considering research, clinic, and forensic field of intervention. Indeed, this book can be considered an excellent synopsis of perspectives, methods, empirical evidence, and international references.Books on Demand GmbH, Überseering 33, 22297 Hamburg 146 pp. Englisch.

The technical methods used are wide, innovative, as well as classic and reflect the knowledge presented in each chapter. The last chapter, however, deals with a new conceptual and methodological approach for the evaluation of volcanic risk. All these volcanoes (except Somma-Vesuvius volcano) are poorly studied so they deserve more attention, which is the goal of this volcanological book. Further studies are welcome to deepen the knowledge of each of the volcanoes presented.Books on Demand GmbH, Überseering 33, 22297 Hamburg 116 pp. Englisch.

Buch. Zustand: Neu. Neuware -Nuclear magnetic resonance (NMR) has evolved as a versatile tool in chemistry and biology. This scientific technique is based on the detection of magnetic moments of atomic nuclei arising due to an intrinsic property called spin because of their precession in static magnetic fields. Nuclei are excited by radio frequency (RF) magnetic fields and subsequently their precession is observed by the voltage they induce on an induction coil as they precess. In this book, we present some of the most exciting developments in the field of NMR: for example, new developments in NMR instrumentation, new magnet technology, RF coil design, the design of novel NMR sensors, and new developments of methods in solution and solid-state NMR These range from new methods for the fast acquisition of 2D spectrum to NMR studies of molecular interactions in ionic solutions. Solid-state methods for the analysis of polyvinyl chloride and NMR studies of torsion angles in polypeptides are also included. The book will be a useful reference for practitioners in the field and at the same time will appeal to a broad audience interested in the general area of NMR.Books on Demand GmbH, Überseering 33, 22297 Hamburg 146 pp. Englisch.
