A smart superhero book for girls with plenty of glitter--perfect for fans of The Powerpuff Girls. It all started with the mysterious purple goo . . . What happens when four best friends find themselves splattered with a bubbling, genetically altering substance during a seemingly innocent sleepover in a secret, see-through, high-tech, futuristic lab? They develop superpowers, that's what! Iris, Cheri, Scarlet, and Opaline are destined to become . . . THE ULTRA VIOLETS IRIS: Visionary, artist, leader—the glitter glue that holds the group together! CHERI: A girly girl on platform rollerskates who's never met a rescue puppy or a nail polish she didn’t immediately-and-madly love. SCARLET: Short enough that you won’t see her sneaking up behind you. Freckled enough that you might mistake her for innocent. But look out! OPALINE: Loveable, huggable, supershy, sweet as pie . . . or is she? THE FUCHSIA IS NOW!

The develop superpowers, that’s what! Iris, Cheri, Scarlet, and maybe Opaline have become . . . THE ULTRA VIOLETS After a close encounter with Opaline's pugnacious perfume at her baddie birthday party in book 2, the Ultra Violets realize they have a lot of cleaning up to do. When IRIS lets her purple flag fly, the UVs decide to reveal their true colors to Sync City. CHERI is pleased with the applause, but after a little mathematical deduction, she knows the peace won't last long. BeauTek and the mutants are scheming up something sinister in the Mall of No Returns. And then SCARLET overhears the Black Swans whispering about a mysterious BeauTekification plan and decides to do a little investigating, dropkick style. Just as the skies are starting to look particularly stormy, OPAL asks to be an Ultra Violet again. Can the girls trust their previously evil friend? In this exciting third book, the Ultra Violets must team up to save SyncCity from the smelly Joan River—and kick some evil mutant BeauTek butt! Dorks are done and . . . the fuchsia is now!

This book provides a comprehensive overview of the state-of-the-art in group III-nitride based ultraviolet LED and laser technologies, covering different substrate approaches, a review of optical, electronic and structural properties of InAlGaN materials as well as various optoelectronic components. In addition, the book gives an overview of a number of key application areas for UV emitters and detectors, including water purification, phototherapy, sensing, and UV curing. The book is written for researchers and graduate level students in the area of semiconductor materials, optoelectronics and devices as well as developers and engineers in the various application fields of UV emitters and detectors.

Almost seventeen-year-old Alison, who has synesthesia, finds herself in a psychiatric facility accused of killing a classmate whose body cannot be found.

Welcome to Ultraviolet Grasslands: 2E the roleplaying game of heroes on a strange trip through mythic steppes in search of lost time, broken space, and deep riffs.Ultraviolet Grasslands is a tabletop role-playing game book, half setting, half adventure, and half epic trip; inspired by psychedelic heavy metal, the Dying Earth genre, and classic Oregon Trail games. It leads a group of 'heroes' into the depths of a vast and mythic steppe filled with the detritus of time and space and fuzzy riffs.

What happens when four best friends find themselves splattered with a purple, bubbling, genetically altering substance during a seemingly innocent sleepover in a secret, see-through, high-tech, futuristic lab? They develop superpowers, that's what! The second entry of a new series.

The main goal of the book is to provide a systematic and didactic approach to the physics and technology of free-electron lasers. Numerous figures are used for illustrating the underlying ideas and concepts and links to other fields of physics are provided. After an introduction to undulator radiation and the low-gain FEL, the one-dimensional theory of the high-gain FEL is developed in a systematic way. Particular emphasis is put on explaining and justifying the various assumptions and approximations that are needed to obtain the differential and integral equations governing the FEL dynamics. Analytical and numerical solutions are presented and important FEL parameters are defined, such as gain length, FEL bandwidth and saturation power. One of the most important features of a high-gain FEL, the formation of microbunches, is studied at length. The increase of gain length due to beam energy spread, space charge forces, and three-dimensional effects such as betatron oscillations and optical diffraction is analyzed. The mechanism of Self-Amplified Spontaneous Emission is described theoretically and illustrated with numerous experimental results. Various methods of FEL seeding by coherent external radiation are introduced, together with experimental results. The world’s first soft X-ray FEL, the user facility FLASH at DESY, is described in some detail to give an impression of the complexity of such an accelerator-based light source. The last chapter is devoted to the new hard X-ray FELs which generate extremely intense radiation in the Angstrøm regime. The appendices contain supplementary material and more involved calculations.
