The Handbook of Ion Sources delivers the data needed for daily work with ion sources. It also gives information for the selection of a suitable ion source and ion production method for a specific application. The Handbook concentrates on practical aspects and introduces the principle function of ion sources. The basic plasma parameters are defined and discussed. The working principles of various ion sources are explained, and examples of each type of ion source are presented with their operational data. Tables of ion current for various elements and charge states summarize the performance of different ion sources. The problems related to the production of ions of non-gaseous elements are detailed, and data on useful materials for evaporation and ion source construction are summarized. Additional chapters are dedicated to extraction and beam formation, ion beam diagnosis, ion source electronics, and computer codes for extraction, acceleration, and beam transport. Emittance and brilliance are described and space charge effects and neutralization discussed. Various methods for the measurement of current, profile, emittance, and time structure are presented and compared. Intensity limits for these methods are provided for different ion energies. Typical problems related to the operation of ion source plasmas are discussed and practical examples of circuits are given. The influence of high voltage on ion source electronics and possibilities for circuit protection are covered. The generation of microwaves and various microwave equipment are described and special problems related to microwave operation are summarized. The Handbook of Ion Sources is a valuable reference on the subject, of benefit to practitioners and graduate students interested in accelerators, ion implantation, and ion beam techniques.

Dieses Buch aus der Anti-Stress-Trainer-Reihe wurde von Gastronomen für Gastronomen geschrieben. Die beiden Autoren haben selbst in einem kleinen Familienbetrieb den stressigen Alltag hautnah erlebt. Mit allen Facetten der zwischenmenschlichen Beziehungen im eigenen Team und mit den Gästen entpuppen sich viele alltägliche Situationen als Stressbringer. Leider bleibt oft keine Zeit, sich schon an der Wurzel darum zu kümmern und zu erkunden wie und wo der Stress entsteht. Erst bei Eskalationen einzugreifen, ist sehr zeitaufwendig und meist ist das Kind schon in den Brunnen gefallen. Dieser Ratgeber gibt dem Leser aus der Branche mit vielen Beispielen und Abhilfetipps einfache und pragmatische Lösungen an die Hand . Nicht alle auf einmal, sondern wohldosiert je nach Zeit und Möglichkeiten, können Gastronomen kapitelweise lesen und ausprobieren. Die Autoren erzählen eigene Geschichten sowie Erfahrungen und welche Methoden sie als Gastronomen und Coaches angewendet haben, um Stresssituationen zu erkennen und für die Zukunft zu verringern. Immer geschrieben mit einem für die Branche üblichen Augenzwinkern und einer Portion Selbstironie.

Structured Biological Modelling presents a straightforward introduction for computer-aided analysis, mathematical modelling, and simulation of cell biological systems. This unique guide brings together the physiological, structural, molecular biological, and theoretical aspects of the signal transduction network that regulates growth and proliferation in normal and tumor cells. It provides comprehensive survey of functional and theoretical features of intracellular signal processing and introduces the concept of cellular self-organization. Exemplified by oscillatory calcium waves, strategies for the design of computer experiments are presented that can assist or even substitute for time-consuming biological experiments. The presented minimal model for proliferation-associated signal transduction clearly shows the alterations of the cellular signal network involved in neoplastic growth. This book will be useful to cell and molecular biologists, oncologists, physiologists, theoretical biologists, computer scientists, and all other researchers and students studying functional aspects of cellular signaling.
