Designing and building power semiconductor modules requires a broad, interdisciplinary base of knowledge and experience, ranging from semiconductor materials and technologies, thermal management, and soldering to environmental constraints, inspection techniques, and statistical process control. This diversity poses a significant challenge to engine
During the early twentieth century, Shanghai was the center of China's new media culture. Described by the modernist writer Mu Shiying as "transplanted from Europe" and “paved with shadows,” for many of its residents Shanghai was a city without a past paradoxically haunted by the absent past’s traces. In Shadow Modernism William Schaefer traces how photographic practices in Shanghai provided a forum within which to debate culture, ethnicity, history, and the very nature of images. The central modernist form in China, photography was neither understood nor practiced as primarily a medium for realist representation; rather, photo layouts, shadow photography, and photomontage rearranged and recomposed time and space, cutting apart and stitching places, people, and periods together in novel and surreal ways. Analyzing unknown and overlooked photographs, photomontages, cartoons, paintings, and experimental fiction and poetry, Schaefer shows how artists and writers used such fragmentation and juxtaposition to make visible the shadows of modernity in Shanghai: the violence, the past, the ethnic and cultural multiplicity excluded and repressed by the prevailing cultural politics of the era and yet hidden in plain sight.
Radiation Oncology provides residents, fellows, and clinicians with a practical, evidence-based guide to the current management of difficult cases in radiation oncology. Emphasis is on the management of those clinical challenges commonly seen in practice that the community practitioner would normally handle without outside referral. The book offers comparisons of treatment approaches to difficult situations, allowing the reader to compare their current treatment approach to that of experts and others in the community. Radiation Oncology is organized in seven sections corresponding to the major treatment areas of radiation oncology. Each section includes three cases to illustrate specific clinical challenges for which there is no clear treatment protocol. The case discussion includes an expert opinion on optimal management along with alternatives from a second academic expert's perspective and from a community practitioner's perspective. Radiation Oncology features: Evidence-based approach to difficult management challenges in radiation oncology Expert authors provide evidence assessment and management summaries through presentation of relevant cases Community practitioner reviewers ensure real-world relevance of each discussion Reviews the most relevant literature pertaining to the challenging scenarios clinicians encounter every day Management alternatives allow discussion of the full range of management options and specifics for difficult problems including hardline recommendations
With platinum and rhodium, palladium is one of the most important members of the platinum metal group. The last Gmelin treatment of it was in 1942, and knowledge of its properties and chemistry has made enormous strides since then. This volume is primarily concerned with binary compounds and with the coordination complexes derived from them. Although it is a member of the nickel-palladium-platinum triad, it more closely resernblas platinum in its binary and coordination chemistry, though being a second-row transition element it displays less tendency than does platinum to assume higher oxidation states. ln heterogeneous and homogeneous catalysis, referred to at appropriate points, palladium and its complexes are of great importance in bulk and fine chemieals production, effecting a wide variety of organic transformations. The arrangement of material in this volume follows the traditional Gmelin arrangement. Within each category of compounds or complexes the material is arranged, as usual, in order of ascending metal oxidation states (e. g., palladium(ll) precedes palladium(IV)). The chemistry of the palladium-hydrogen system is so large that it merits a separate volume, so this book starts with the binary oxides and oxopalladates followed by hydroxides, hydroxo complexes and aquo complexes. Then nitrides and nitrates are treated. They are followed by the large chapters on halides and their complexes (172 pages). The largest single chapter in this volume (11 0 pages) deals with chlorides, chloropalladates and other chloro complexes.
