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.

Studies of herbivory provide important insights into fundamental questions in many areas of the biological sciences. The focus on natural systems is more effective for the prediction of potential changes in ecosystems, given that agricultural systems are designed to create an equilibrium that optimizes the productive process. Given the ramifications of the processes related to herbivory, studies based on complementary approaches are necessary for a better understanding of the different aspects of the ecological process. This book attempts to expand on these different aspects of herbivory by presenting a multidisciplinary approach to a number of different themes, focusing on topics that range from basic research in natural habitats to the intrinsic relationships between animals and plants in agricultural systems.

The Earth is the only planet in our solar system that supports life. The complex process of evolution occurred on Earth only because of some unique environmental conditions that were present: water, an oxygen-rich atmosphere, and a suitable surface temperature. Climate change refers to a statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period (typically decades or longer). Thus, it requires field of attention towards reduction in the rise in atmospheric temperature, by controlling emitted greenhouse gases into the atmosphere in order to preserve natural resources and by introducing new technologies on alternative fuels.This book presents the fundamental effect on the origin of climate change, impacts over ice cap, melting of Arctic ice, rise in sea level and related technologies that can be implemented to cultivate our land for agriculture, growing forestation to reduce the impact of temperature rise and disaster on human being as well as on other livelihood. This also need to strive for novel policies that world leader should adopt.

Recently, some SiC power devices such as Schottky-barrier diodes (SBDs), metal-oxide-semiconductor field-effect-transistors (MOSFETs), junction FETs (JFETs), and their integrated modules have come onto the market. However, to stably supply them and reduce their cost, further improvements for material characterizations and those for device processing are still necessary. This book abundantly describes recent technologies on manufacturing, processing, characterization, modeling, and so on for SiC devices. In particular, for explanation of technologies, I was always careful to argue physics underlying the technologies as much as possible. If this book could be a little helpful to progress of SiC devices, it will be my unexpected happiness.

This book reflects a major medical problem which is still under thorough studies. There is a number of clinical cases corresponding directly or indirectly to a certain alteration of the immune system, thus leading to various pathologic conditions. The unique defense, what humans have with their immunity, is rather often affected by infections, tumor processes, organ, tissue and cell transplantation, allergy, autoimmune processes, as well as different influences by the environment. The Book has an international team of authors all contributing to the investigation of the questions of what, why, how, when and where the immune system deviates from its normal function, what clinical consequences are manifested and is there a way to prevent and treat the immunodeficiency cases. This Book can be a very good teaching tool for students and post-docs of medicine and biology, but it also provides updated information for the colleagues immunologists, microbiologists, virologists, chemotherapists, oncologists, hematologists, transplantologists and pathologist.

This book discusses aspects of laser pulses generation, characterization, and practical applications. Some new achievements in theory, experiments, and design are demonstrated. The introductive chapter shortly overviews the physical principles of pulsed lasers operation with pulse durations from seconds to yoctoseconds.
