Gerhard Wanner – författare

A concise and authoritative introduction to scanning electron microscopy in the biological sciences

In A Practical Guide to Scanning Electron Microscopy distinguished electron microscopist Gerhard Wanner delivers a practical handbook for biological scientists working with microbial, plant, and animal cells and tissues, enabling them to successfully apply scanning electron microscopy (SEM) to their object of study.

The book begins with an introduction to the principles of electron microscopy and the operation of electron microscopes before moving on to describe the preparation and mounting of specimens. It also explores the process of recoding images and their subsequent analysis, along with a wide range of advanced microscopy techniques, including cryo-SEM, FIB-SEM tomography, and stereo-SEM.

Scanning Electron Microscopy in the Biosciences contains hundreds of carefully selected microscopic images, as well as hands-on, step-by-step guidance required to perform a successful TEM experiment. Readers will also find:

Perfect for cell biologists and microbiologists, A Practical Guide to Scanning Electron Microscopy in the Biosciences also belongs in the libraries of neurobiologists and biophysicists.

Numerical methods that preserve properties of Hamiltonian systems, reversible systems, differential equations on manifolds and problems with highly oscillatory solutions are the subject of this book. A complete self-contained theory of symplectic and symmetric methods, which include Runge-Kutta, composition, splitting, multistep and various specially designed integrators, is presented and their construction and practical merits are discussed. The long-time behaviour of the numerical solutions is studied using a backward error analysis (modified equations) combined with KAM theory. The book is illustrated by many figures, it treats applications from physics and astronomy and contains many numerical experiments and comparisons of different approaches. The second edition is substantially revised and enlarged, with many improvements in the presentation and additions concerning in particular non-canonical Hamiltonian systems, highly oscillatory mechanical systems, and the dynamics of multistep methods.

In this textbook the authors present first-year geometry roughly in the order in which it was discovered. The first five chapters show how the ancient Greeks established geometry, together with its numerous practical applications, while more recent findings on Euclidian geometry are discussed as well. The following three chapters explain the revolution in  geometry due to the progress made in the field of algebra by Descartes, Euler and Gauss. Spatial geometry, vector algebra and matrices are treated in chapters 9 and 10. The last chapter offers an introduction to projective geometry, which emerged in the 19thcentury.

Complemented by numerous examples, exercises, figures and pictures, the book offers both motivation and insightful explanations, and provides stimulating and enjoyable reading for students and teachers alike.

Dieses Buch führt Sie in die Programmierung verteilter Systeme in Java ein. Besonderer Wert wird auf die Realisierung serverseitiger Anwendungen im Rahmen der Java EE-Architektur gelegt. Schritt für Schritt lernen Sie alle wichtigen Technologien und Bestandteile von Enterprise Java sowie deren Zusammenspiel kennen.

Jedes Kapitel enthält zahlreiche Beispiele und Übungsaufgaben, sodass der Leser nach der Lektüre des Buches in der Lage ist, komponentenbasierte Webanwendungen auf Basis der Java Enterprise-Architektur zu erstellen.

Alle Übungen inklusive Lösungen sowie die Abbildungen des Buches stehen online auf der Webseite des Verlags zur Verfügung.

Das Buch adressiert die zwei Themen Erstellung ressourceneffizienter Software sowie den ressourceneffizienten Betrieb von Software. Für die Mehrheit aller Unternehmen in Deutschland sind bei der Entwicklung von Software die Dimensionen „in budget“, „in time“ und „in function“ wichtig. Die Dimension „in climate“ gewinnt vor dem Hintergrund der Klima- und der Energiekrise stark an Bedeutung. Dabei muss die Dimension „in climate“ nicht im Kontrast zu den anderen Dimensionen stehen. Bei näherer Betrachtung kann sie sogar die anderen Dimensionen ergänzen. In Bezug auf den Betrieb von IT-Systemen liegt aktuell der Fokus bei den deutschen Firmen auf Performance und Verfügbarkeit. Einbußen in diesen beiden Bereichen wird oftmals mit einem Mehr an Infrastruktur begegnet, welches höheren Ressourcenverbrauch bedeutet und damit ggf. höhere CO2-Emissionen impliziert. Dabei müssen Performance und Verfügbarkeit nicht im Widerspruch zu moderaten CO2-Emissionen stehen. Dieses Buch stellt zunächst die Ergebnisse einer Umfrage unter Entscheiderinnen und Entscheidern zum Thema Green-IT dar, mit Fragen zu einer nachhaltigen IT in Bezug auf die Entwicklung und den Betrieb von Software. Aufbauend auf der Umfrage werden konkrete Maßnahmen zur Reduktion von CO2 beim Entwurf und beim Bau von Software dargestellt sowie Möglichkeiten eines energieeffizienten Betriebs im eigenen Rechenzentrum und in der Cloud aufgezeigt. Neben einem ausführlichen Theorieteil bietet das Buch mehrere Best-Practice-Beispiele und eine illustrative Fallstudie.
