Book Description
The book reviews the most interesting research concerning the radiation defects formed in 6H-, 4H-, and 3C-SiC under irradiation with electrons, neutrons, and some kinds of ions. The electrical parameters that make SiC a promising material for applications in modern electronics are discussed in detail. Specific features of the crystal structure of SiC are considered. It is shown that, when wide-bandgap semiconductors are studied, it is necessary to take into account the temperature dependence of the carrier removal rate, which is a standard parameter for determining the radiation hardness of semiconductors. The carrier removal rate values obtained by irradiation of various SiC polytypes with n- and p-type conductivity are analyzed in relation to the type and energy of the irradiating particles. The influence exerted by the energy of charged particles on how radiation defects are formed and conductivity is compensated in semiconductors under irradiation is analyzed. Furthermore, the possibility to produce controlled transformation of silicon carbide polytype is considered. The involvement of radiation defects in radiative and nonradiative recombination processes in SiC is analyzed. Data are also presented regarding the degradation of particular SiC electronic devices under the influence of radiation and a conclusion is made regarding the radiation resistance of SiC. Lastly, the radiation hardness of devices based on silicon and silicon carbide are compared.

the strategies' performance outcomes. Drawing on organizational learning theory, she identifies the organizational abilities and processes that constitute a firm's Strategy Implementation Capability construct and shows empirically that the concept is very valuable in explaining how innovative strategies translate into a firm's performance.

Book Description
When considering inequality, one goal for educators is to enhance critical engagement to allow learners an opportunity to participate in an inquiry process that advances democracy. Service?learning pedagogy offers an opportunity to advance engaged?learning opportunities within higher education. This is particularly important given the power dynamics that are endemic within conversations about education, including the conversations around the Common Core, charter schools, and the privatization of education. Critical inquiry is central to the ethos of service?learning pedagogy, a pedagogy that is built upon community partner participation and active reflection. Within higher education, service?learning offers an important opportunity to enhance practice within the community, allowing students to engage stakeholders and youth which is particularly important given the dramatic inequalities that are endemic in today’s society.

Book Description
In their introduction, "Angels of History, Demons of History," the editors allude to the complex social anxieties projected into concerns about youth. Contributors examine the problems of identity, juvenile delinquency, intergenerational tensions, and downward mobility, as well as more positive aspects of youth culture (art, activism, and cyber-communities)--in the early 20th century, the World War II/postwar era, and the contemporary scene.

Book Description
Operating at a high level of fuel efficiency, safety, proliferation-resistance, sustainability and cost, generation IV nuclear reactors promise enhanced features to an energy resource which is already seen as an outstanding source of reliable base load power. The performance and reliability of materials when subjected to the higher neutron doses and extremely corrosive higher temperature environments that will be found in generation IV nuclear reactors are essential areas of study, as key considerations for the successful development of generation IV reactors are suitable structural materials for both in-core and out-of-core applications. Structural Materials for Generation IV Nuclear Reactors explores the current state-of-the art in these areas. Part One reviews the materials, requirements and challenges in generation IV systems. Part Two presents the core materials with chapters on irradiation resistant austenitic steels, ODS/FM steels and refractory metals amongst others. Part Three looks at out-of-core materials. Structural Materials for Generation IV Nuclear Reactors is an essential reference text for professional scientists, engineers and postgraduate researchers involved in the development of generation IV nuclear reactors. - Introduces the higher neutron doses and extremely corrosive higher temperature environments that will be found in generation IV nuclear reactors and implications for structural materials - Contains chapters on the key core and out-of-core materials, from steels to advanced micro-laminates - Written by an expert in that particular area
