A historiografia das produções em periódicos de Sadao Omote Historiography of production in periodicals by Sadao Omote
Get PDFbuscamos através deste texto materializar o percurso histórico trilhado pelos artigos em periódicos de Sadao Omote ao longo de suas três décadas de produção acadêmico - científica. Para tanto, recorremos ao currículo Lattes do referido autor e listamos todos seus artigos (41) incorporados na referida plataforma. Após este breve caminho exploratório, realizamos uma árida busca pela totalidade destes textos, apenas consubstanciada com a ajuda do próprio autor, o qual nos disponibilizou os textos faltantes. Feito isto, lemos minuciosamente cada artigo três vezes, extraindo deles os principais conceitos referentes à Educação Especial como campo de conhecimento. A intersecção destes elementos corporifica-se na presente análise, dividida em três partes, a saber: a) conceitos basilares trabalhados por Omote no campo da Educação Especial; b) idéias e apontamentos sobre o fenômeno da inclusão, dirigindo especial ênfase aos aspectos relacionados ao ambiente escolar, e; c) principais referências e temas retratados pelo referido autor; cuja concretude objetiva destacar criticamente os principais apontamentos de Sadao Omote referente à Educação Especial, nosso campo de estudo, e possíveis caminhos dialéticos à edificação de um sistema educacional que seja radical na qualidade de ensino por ele ministrada.in this text we attempted to track the historical course in the production of articles by Sadao Omote over the three decades of his academic production. We referred to his Vitae registered on the Lattes platform, where he listed all of his published articles (41). After this exploratory overview, we performed a search that enabled us to find all of his texts, which we were able to achieve with the author's help, as he provided us with the missing texts. The next stage required us to carefully read each article three times, extracting the main concepts related to Special Education as a field of knowledge. The intersection of these elements constitutes the basis of this analysis, divided into three parts, namely: a) basic concepts Omote worked on in the field of Special Education; b) ideas and notes on the inclusion paradigm, with special attention given to aspects relating to the school environment, and; c) main references and themes discussed by the author. Our objective was to critically highlight the main issues Sadao Omote has worked on in the field of Special Education, with possibilities for a dialectical construction of an educational system that stands for quality in teaching, as he has advocated
The structure and the evolution of essential patents for standards: Lessons from three IT standards
Get PDFThis paper examines the structure and the evolution of the patents declared as essential for three major technical standards in information technology (MPEG2, DVD and W-CDMA). These standards have many essential patents, which are owned by many firms with different interests. Many patents have been applied even after the standard was set. We analyze three important reasons for why the essential patents are many and increase over time: they cover a number of different technology fields, there exist R&D competition even in a narrowly defined technology field and a firm can expand its patent portfolio by using continuations and other practices based on the priority dates of its earlier filed patent applications in the USA. Around 40% of the essential US patents for MPEG2 and DVD standards have been obtained by using these applications. However, our empirical analysis suggests that a firm with pioneering patents does not obtain more essential patents, using these practices.standard, essential patent, continuations

Observation of macroscopic stability of weakly magnetized Li+ ion beams near the Brillouin density limit

No full textThis paper reviews the research on the reversed field pinch (RFP) in the last three decades. Substantial experimental and theoretical progress and transformational changes have been achieved since the last review (Bodin 1990 Nucl. Fusion 30 1717-37). The experiments have been performed in devices with different sizes and capabilities. The largest are RFX-mod in Padova (Italy) and MST in Madison (USA). The experimental community includes also EXTRAP-T2R in Sweden, RELAX in Japan and KTX in China. Impressive improvements in the performance are the result of exploration of two lines: the high current operation (up to 2 MA) with the spontaneous occurrence of helical equilibria with good magnetic flux surfaces and the active control of the current profile. A crucial ingredient for the advancements obtained in the experiments has been the development of state-of-art active feedback control systems allowing the control of MHD instabilities in presence of a thin shell. The balance between achievements and still open issues leads us to the conclusion that the RFP can be a valuable and diverse contributor in the quest for fusion electricity
