Covering many techniques widely used in research, this book will help researchers in the physical sciences and engineering solve troublesome - and potentially very time consuming - problems in their work. The book deals with technical difficulties that often arise unexpectedly during the use of various common experimental methods, as well as with human error. It provides preventive measures and solutions for such problems, thereby saving valuable time for researchers. Some of the topics covered are: sudden leaks in vacuum systems, electromagnetic interference in electronic instruments, vibrations in sensitive equipment, and bugs in computer software. The book also discusses mistakes in mathematical calculations, and pitfalls in designing and carrying out experiments. Each chapter contains a summary of its key points, to give a quick overview of important potential problems and their solutions in a given area.

This full-colour undergraduate textbook, based on a two semestercourse, presents the fundamentals of biological physics,introducing essential modern topics that include cells, polymers,polyelectrolytes, membranes, liquid crystals, phase transitions,self-assembly, photonics, fluid mechanics, motility, chemicalkinetics, enzyme kinetics, systems biology, nerves, physiology, thesenses, and the brain. The comprehensive coverage, featuring in-depth explanations ofrecent rapid developments, demonstrates this to be one of the mostdiverse of modern scientific disciplines. The Physics of Living Processes: A Mesoscopic Approach iscomprised of five principal sections: • Building Blocks • Soft Condensed Matter Techniques in Biology • Experimental Techniques • Systems Biology • Spikes, Brains and the Senses The unique focus is predominantly on the mesoscale —structures on length scales between those of atoms and themacroscopic behaviour of whole organisms. The connections betweenmolecules and their emergent biological phenomena provide a novelintegrated perspective on biological physics, making this animportant text across a variety of scientific disciplines includingbiophysics, physics, physical chemistry, chemical engineering andbioengineering. An extensive set of worked tutorial questions are included,which will equip the reader with a range of new physical tools toapproach problems in the life sciences from medicine,pharmaceutical science and agriculture.

Schon die erste Auflage des englischen Lehrbuchs 'Fundamentals of Photonics' zeichnete sich durch seine ausgewogene Mischung von Theorie und Praxis aus, und deckte in detaillierter Darstellung die grundlegenden Theorien des Lichts ab. Es umfasste sowohl die Themen Strahlenoptik, Wellenoptik, elektromagnetische Optik, Photonenoptik, sowie die Wechselwirkung von Licht und Materie, als auch die Theorie der optischen Eigenschaften von Halbleitern. Die Photonik-Technologie hat eine rasante Entwicklung genommen seit der Publikation der ersten Ausgabe von 'Fundamentals of Photonics' vor 15 Jahren. Die nun vorliegende Zweite Auflage des Marksteins auf dem Gebiet der Photonik trägt mit zwei neuen und zusätzlichen Kapiteln den neuesten technologischen Fortschritten Rechnung: Photonische Kristalle sowie Ultrakurzpuls-Optik. Zudem wurden alle Kapitel gründlich überarbeitet und viele Abschnitte hinzugefügt, so z.B. über Laguerre-Gauss Strahlen, die Sellmeier-Gleichung, Photonenkristall-Wellenleiter, photonische Kristallfasern, Mikrosphären-Resonatoren, Optische Kohärenz Tomographie, Bahndrehimpuls des Photons, Bohrsche Theorie, Raman-Verstärker, rauscharme Avalanche-Photodioden, Abstimmkurven und Dispersions-Management.

Sensoren sind überall. Die Welt ist voll von ihnen: Infrarotsensoren in Bewegungsmeldern, CO2-Detektoren für das Haus – und in Ihrem Smartphone finden sich winzige Beschleunigungsmesser, GPS-Module und Kameras. Dank der großen Verbreitung von Mobilgeräten sind Sensoren erstaunlich erschwinglich geworden. Sie können günstige Sensoren und Mikrocontroller-Boards kombinieren, um eigene Devices zu bauen. Dieses umfangreiche und in Farbe illustrierte Buch zeigt Ihnen in einer Reihe von Projekten, wie Sie Sensoren anschließen und auslesen. Sie erfahren, wie Sie die populären Arduino- und Raspberry Pi-Boards einsetzen, um Daten in einfachen, selbst geschriebenen Programmen zu verarbeiten. Mit diesem Buch schreiben Sie Programme und bauen Geräte für das Messen von: Rotation mit einem Potentiometer, Abstand mit Ultraschall, Annäherung per Infrarot, Helligkeit mit einem Fotowiderstand, Temperatur mit einem Thermometer, Kraft mit einem Drucksensor. Sie werden mit Widerstandssensoren arbeiten, aber auch mit Schaltern, Messwandlern, Potentiometern, Summern, 555-Timern und Spannungsteilern. Es gibt so viele Sinneswahrnehmungen da draußen, die Sie erfassen und verarbeiten können. Wie fangen Sie diese ein?

This book intended for shop use tries to familiarize the reader with the peculiari ties of a hardening method which due to its many advantages is now in use,many shops. A general knowledge of the principles of hardening and heat treating is presumed. Introduction 1. The name of the process. Flame hardening is a method derived from the old quench hardening and is used for the surface hardening of heat treatable steels. Flame hardening is so named in analogy to flame cutting as the use of a flame is a distinctive feature of this process as opposed to the use of a furnace. 2. Characteristics of flame hardening. In flame hardening the area to be 6 hardened is heated with a burner of large heat capacity (approx. 0.5 · 10 kcaljhr/ meter of flame lengths or 50,000 BTUfhr/inch of flame length) supplied with a mixture of fuel gas and oxygen. The hardening temperature is thus reached in so short a time at the surface that a heat jam is created, that is, more heat is supplied to the surface than can be dissipated to the interior of the workpiece. As the querr ehing takes place immediately after the heating the penetration of the heat to greater depth is prevented and only the outer layer subject to wear is hardened. The core of the workpiece remains unaffected by this heat treatment in cantrast to the other hardening methods where the entire piece is through heated in a furnace.
