Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of Nonistopic DNA Probe Techniques in 1992, the move away from radioactive materials for research and diagnostics has continued. This is due in part to public awareness of the hazards of radioactive waste and laws making radioactive disposal more difficult and costly and to improvement in both the sensitivity and convenience of nonisotopic techniques. Several new nonisotopic techniques have been developed and substantial improvements made to existing nonisotopic methods since 1992, and these are now included in Nonisotopic Probing, Blotting, and Sequencing. Nonisotopic Probing, Blotting, and Sequencing is an updated, expanded edition of the bestseller, Nonisotopic DNA Probe Techniques. It has been thoroughly revised to include the latest improvements in nonisotopic tagging techniques for macromolecules. Like its predecessor, it enables researchers to select the best nonisotopic method for their needs and maximize success by following its straightforward protocols. - Provides strategies and detailed procedures for labeling, blotting, and probing specific nucleic acid sequences and, with this edition, protein molecules - Gives protocols for nonisotopic DNA sequencing - new in this edition - Gives extensive, practical information - Presents background information for each method - Provides expert accounts from the inventor or developer of each method - Contains seven entirely new chapters - Covers all major types of nonisotopic procedures for labeling and detection

Available in PDF, EPUB and Kindle. Book excerpt: Compared to traditional electrical filaments, arc lamps, and fluorescent lamps, solid-state lighting offers higher efficiency, reliability, and environmentally friendly technology. LED / solid-state lighting is poised to take over conventional lighting due to cost savings—there is pretty much no debate about this. In response to the recent activity in this field, Fundamentals of Solid-State Lighting: LEDs, OLEDs, and Their Applications in Illumination and Displays covers a range of solid-state devices, technologies, and materials used for lighting and displays. It also examines auxiliary but critical requirements of efficient applications, such as modeling, thermal management, reliability, and smart lighting. The book discusses performance metrics of LEDs such as efficiency, efficacy, current–voltage characteristics, optical parameters like spectral distribution, color temperature, and beam angle before moving on to luminescence theory, injection luminescence, radiative and non-radiative recombination mechanisms, recombination rates, carrier lifetimes, and related topics. This lays down the groundwork for understanding LED operation. The book then discusses energy gaps, light emission, semiconductor material, special equipment, and laboratory facilities. It also covers production and applications of high-brightness LEDs (HBLEDs) and organic LEDs (OLEDs). LEDs represent the landmark development in lighting since the invention of electric lighting, allowing us to create unique, low-energy lighting solutions, not to talk about their minor maintenance expenses. The rapid strides of LED lighting technology over the last few years have changed the dynamics of the global lighting market, and LEDs are expected to be the mainstream light source in the near future. In a nutshell, the book traces the advances in LEDs, OLEDs, and their applications, and presents an up-to-date and analytical perspective of the scenario for audiences of different backgrounds and interests.

Available in PDF, EPUB and Kindle. Book excerpt: Fundamental Physics of Radiology, Third Edition provides a general introduction to the methods involving radioactive isotopes and ultrasonic radiations. This book provides the fundamental principles upon which the clinical uses of radioactive isotopes and ultrasonic radiation depend. Organized into four sections encompassing 45 chapters, this edition begins with an overview of the basic facts about matter and energy. This text then examines the technical details of some practical X-ray tubes. Other chapters consider the action of the X-rays on the screen to produce an emission of visible light photons in amount proportional to the incident X-ray intensity. This book discusses as well the fundamental aspects of the physical principles of radiotherapy, in which most attention is being given to gamma- and X-rays. The final chapter deals with the provision of adequate barriers and protective devices to guarantee the safety of the workers concerned. This book is a valuable resource for radiologists, physicists, and scientists.
