Book Description
Reactive oxygen species (ROS) influence various physiological processes including host defense, hormone biosynthesis, and cellular signaling. Increased ROS production (oxidative stress) is implicated in many diseases of the cardiovascular system, including hypertension, atherosclerosis, cardiac failure, stroke, diabetes, and kidney disease. ROS are produced throughout the cardiovascular system, in the kidney and central and peripheral nervous system. A major source for cardiovascular, renal, and neural ROS is a family of non-phagocytic NAD(P)H oxidases, including the prototypic Nox2 homologue-based NAD(P)H oxidase, as well as other NAD(P)H oxidases, such as Nox1 and Nox4. Other possible sources include mitochondrial electron transport enzymes, xanthine oxidase, cyclooxygenase, lipoxygenase, and uncoupled nitric oxide synthase (NOS). NAD(P)H oxidase-derived ROS is important in regulating endothelial function and vascular tone and oxidative stress is implicated in endothelial dysfunction, inflammation, hypertrophy, apoptosis, migration, fibrosis, angiogenesis and rarefaction, important processes involved in vascular remodeling in cardiovascular disease. These findings have evoked considerable interest because of the possibilities that therapies targeted against non-phagocytic NAD(P)H oxidase to decrease ROS generation and/or strategies to increase nitric oxide (NO) availability and antioxidants may be useful in minimizing vascular injury and thereby prevent or regress target organ damage associated with hypertension and other cardiovascular diseases.

Book Description
“This friendly book leads us clearly and gracefully from the basics to advanced techniques in photography composition . . . highly recommended.” —Brian Taylor, executive director, Center for Photographic Arts There’s a common misconception that composition is mysterious and that only certain people have that natural gift for the techniques involved. The truth is that composition involves a set of skills that you can master. Just as you can use cookbook recipes to make your favorite meal—you don’t have to be a famous French chef—you also can take amazing photos by just following a recipe! Marc Silber has spent years studying the works of masters and interviewing some of the biggest names in photography. The Secrets to Creating Amazing Photos puts at your fingertips ideas for improving your skills by giving you easy-to-follow “recipes” that will improve your photography right now! Composition is one of the biggest keys to creating photos that others will love. No matter what kind of camera or smartphone you’re using, you can take your photography to the next level and beyond by learning composition tools and secrets known to the masters of the art. With this handy guide, you can flip to the look you want on the spot and follow the recipe for creating an image that inspires you. Use it when you’re out photographing to get new ideas and inspiration. “Buy it, read it and then apply what you have learnt from this superb new book . . . This is a complete must-have, a veritable cornucopia of wisdom gained over decades of experience.” —Gray Levett, editor of Nikon Owner magazine

Book Description
Gas chromatography continues to be one of the most widely used analytical techniques, since its applications today expand into fields such as biomarker research or metabolomics. This new practical textbook enables the reader to make full use of gas chromatography. Essential fundamentals and their implications for the practical work at the instrument are provided, as well as details on the instrumentation such as inlet systems, columns and detectors. Specialized techniques from all aspects of GC are introduced ranging from sample preparation, solvent-free injection techniques, and pyrolysis GC, to separation including fast GC and comprehensive GCxGC and finally detection, such as GC-MS and element-specific detection. Various fields of application such as enantiomer, food, flavor and fragrance analysis, physicochemical measurements, forensic toxicology, and clinical analysis are discussed as well as cutting-edge application in metabolomics is covered.

Book Description
It was our aim to place at the disposal of radiologists within a short time an atlas of high-quality, valuable pictures of abdominal CT without We felt that, the image degradation inherent to slower scanning apparatus. notwithstanding rapid evolution in CT scanning apparatus and the resulting rapid advances in our clinical knowledge about the value, limitations and applications of this new diagnostic imaging modality, an effort should be made to realize an atlas of reference. From more than 7,000 patients studied with abdominal CT, we tried to assemble images with maximal anatomical detail, which implies the use of large window settings, being well aware that in daily routine practice basic CT methodology includes the use of different window settings for optimal information. It was, however, a conscious decision not to use comparative images with large and small window settings in order to stay within a reasonable total number of figures. Much emphasis has been placed upon the use of contrast enhancement by intravenous contrast media. This is based on the conviction that essen tially new and better morphological information about normal and pathological processes within the abdomen can be obtained because short exposure times now allow one to capture the rapidly changing aspect and degree of contrast enhancement of the lesions as a function of their vascu larity.

Book Description
The twelfth-century French poet Chrétien de Troyes is a major figure in European literature. His courtly romances fathered the Arthurian tradition and influenced countless other poets in England as well as on the continent. Yet because of the difficulty of capturing his swift-moving style in translation, English-speaking audiences are largely unfamiliar with the pleasures of reading his poems. Now, for the first time, an experienced translator of medieval verse who is himself a poet provides a translation of Chrétien’s major poem, Yvain, in verse that fully and satisfyingly captures the movement, the sense, and the spirit of the Old French original. Yvain is a courtly romance with a moral tenor; it is ironic and sometimes bawdy; the poetry is crisp and vivid. In addition, the psychological and the socio-historical perceptions of the poem are of profound literary and historical importance, for it evokes the emotions and the values of a flourishing, vibrant medieval past.

Book Description
The petroleum age began about 150 years ago. Easily available energy has s- ported major advances in agriculture, industry, transportation, and indeed many diverse activities valued by humans. Now world petroleum and natural gas s- plies have peaked and their supplies will slowly decline over the next 40–50 years until depleted. Although small amounts of petroleum and natural gas will remain underground, it will be energetically and economically impossible to extract. In the United States, coal supplies could be available for as long as 40–50 years, depending on how rapidly coal is utilized as a replacement for petroleum and natural gas. Having been comfortable with the security provided by fossil energy, especially petroleum and natural gas, we appear to be slow to recognize the energy crisis in the U. S. and world. Serious energy conservation and research on viable renewable - ergy technologies are needed. Several renewable energy technologies already exist, but sound research is needed to improve their effectiveness and economics. Most of the renewable energy technologies are in uenced by geographic location and face problems of intermittent energy supply and storage. Most renewable technologies require extensive land; a few researchers have even suggested that one-half of all land biomass could be harvested in order to supply the U. S. with 30% of its liquid fuel! Some optimistic investigations of renewable energy have failed to recognize that only 0. 1% of the solar energy is captured annually in the U. S.
