Estudo da viabilidade ecônomica para a implementação do reator nuclear SMART no Brasil / Study on the economic feasibility for the implementation of the SMART nuclear reactor in Brazil

Cordelia Mara Fazzio Escanhoela 24 September 2018 (has links)
A energia que sustenta a atividade humana é, hoje, predominantemente elétrica, sendo produzida em sua maior parte por fontes fósseis poluentes, emissoras de gás carbônico. Na busca de soluções para essa problemática, fontes alternativas limpas e sustentáveis têm sido estudadas e já inseridas em diversos países, inclusive no Brasil. Nossa principal fonte, a hidrelétrica, apesar de não poluente corre, hoje, o risco do esgotamento em decorrência de grandes demandas e das mudanças climáticas. Dentre outras fontes brasileiras ainda não intensamente exploradas situam-se a biomassa, eólica, solar e nuclear; a energia nuclear pode ser uma interessante opção pois, além de limpa, oferece as vantagens da disponibilidade de combustível (urânio e tório) e o conhecimento da tecnologia aplicada nas usinas de Angra 1 e 2 e futuramente em Angra 3. A energia nuclear das gerações III+ e IV traz uma proposta bastante promissora em termos de segurança e economia, os reatores inovadores, que estão sendo desenvolvidos em muitos institutos de pesquisa de vários países, entre eles, o Brasil. O presente trabalho considera essa opção e estuda a viabilidade de implementação do reator inovador SMART no Brasil; esse reator foi desenvolvido pelo KAERI; é modular do tipo PWR, apresenta potência de 100 MWe; atende uma demanda de 100.000 habitantes, possui sistema passivo de segurança e configuração integral. O trabalho fundamenta-se em projeções de demanda energética a médio e longo prazo com ênfase na eletricidade. A viabilidade econômica do projeto foi avaliada por meio das técnicas Taxa Interna de Retorno; Valor Presente Líquido; Payback Descontado e Valor do Pagamento Periódico; foram selecionadas e estudadas três tarifas e três formas de captação de recursos; foi também calculado o custo unitário por MWh do reator SMART e comparado ao de uma hidrelétrica de igual potência. Os resultados demostraram que o projeto é viável em quatro situações distintas e o custo unitário resultou 39% inferior ao da hidrelétrica. / The energy that sustains the human activity is, nowadays, predominantly electric, being the most part produced by fossil sources polluting, carbon dioxide emitters. In the search for solutions to this problem, clean and sustainable alternative sources have been studied and already inserted in several countries, including Brazil. Our main source, hydroelectric, although not polluting, has the risk of depletion today, due to big demands and climate change. Among other Brazilian sources identified as viable alternatives and not yet intensely explored are biomass, wind, solar and nuclear; the nuclear power can be an interesting option as, besides being clean, it offers the advantages of fuel availability (uranium and thorium) and the knowledge of the technology applied in Angra 1 and 2 plants and in future in Angra 3. The nuclear energy of the III + and IV generations brings a very promising proposal in terms of safety and economy, which are the innovative reactors that are being developed in research institutes of several countries, including Brazil. The present work considers this option and studies the feasibility of implementing the innovative reactor SMART in Brazil. This reactor was developed by KAERI; it is a modular PWR type; has a power of 100 MWe; meet a demand of 100,000 inhabitants; features passive safety system and integral configuration. The work is based on projections of energy demand in the medium and long-term with emphasis on electricity. The economic viability of the project was evaluated through the Internal Rate of Return techniques; Net Present Value; Discounted Payback and Periodic Payment Amount; three rates and three forms of fundraising were selected and studied; the unit cost per MWh of the SMART reactor was also calculated and compared to a hydroelectric plant of equal power. The results showed that the project is viable in four different situations and the unit cost was 39% lower than the hydroelectric one.

Parques tecnológicos do estado de São Paulo: incentivo ao desenvolvimento da inovação / Science parks in the state of São Paulo: fostering the development of innovation

Melo, Rita de Cássia Nonato 05 March 2015 (has links)
A criação de parques tecnológicos tem sido bastante acionada para incentivar o processo inovador no Brasil. Verifica-se um grande aumento no número de iniciativas de parques tecnológicos, fato que reflete as políticas de incentivo específico aos parques e a importância que a inovação possui como parte do processo de desenvolvimento econômico. Considerados como ambientes propícios às atividades das empresas inovadoras, os parques tecnológicos tem como objetivo reunir elementos específicos que gerem uma sinergia capaz de formar redes de cooperação para a inovação. As relações entre empresas, universidades e centros de pesquisa recebem, portanto, importância destacada uma vez que podem engendrar inovações e transferência de tecnologia. Desta forma, os parques tecnológicos podem constituir meios inovadores que, de acordo com Aydalot (1986), correspondem as condições externas à empresa que impulsionam a adoção da inovação e que podem desempenhar um papel determinante no processo de incubação de inovações. No Brasil, o estado de São Paulo constitui o ente federativo com o maior número de iniciativas de parques tecnológicos e também é o único a possuir uma política específica para o seu fomento, o Sistema Paulista de Parques Tecnológicos - SPTec. Partindo da análise dos parques tecnológicos do estado de São Paulo em operação e com credenciamento definitivo no SPTec, esta tese busca compreender a forma de atuação dos parques no fomento da inovação, como estruturas de apoio e como estruturas capazes de suscitar inovação, podendo compor meios inovadores. / The creation of science parks has been quite adopted to encourage the innovative process in Brazil. There is a large increase in the number of science parks initiatives, a fact that reflects the specific incentive policies to parks and the importance that innovation has as part of the economic development process. Considered environments capable of developing innovative activities in companies, science parks aim to bring together specific elements that create a synergy able to forming collaborative networks for innovation. Relations between companies, universities and research centers receive so prominent importance since they can engender innovation and technology transfer. Thus, science parks can provide innovative environments that, according to Aydalot (1986), correspond to the external conditions that drive enterprise adoption of innovation and that can play a decisive role in the incubation of innovation process. In Brazil, the state of São Paulo is the federal entity with the largest number of initiatives science parks and is also the only one to have a specific policy for promoting them, the Paulista System Technology Parks - SPTec. Based on the analysis of science parks in the state of São Paulo in operation and final accreditation in SPTec, this thesis seeks to understand the modus operandi of the parks in fostering innovation as support structures as structures capable of giving rise to innovation. In this movement, science parks can compose innovative environments.

'Some particulars' : the poetry and practice of Thomas A. Clark

Tarbuck, Alice January 2018 (has links)
This thesis is a critical study of the poetry and practice of Thomas A. Clark. It constitutes the first extended critical study of Clark's work. This thesis orients Clark within a network of influence, both historic and contemporary. It does this in order to contextualise and investigate Clark's innovative use of form, theme, and materiality. In Clark's work, form is used to explore and engage with the natural world. These interactions reveal the primacy of close attention in Clark's work, and his understanding of the ethical relationship between form, content, and the natural world. This thesis isolates four geographic features in Clark's work as lenses through which to explore his practice: the Field, the Garden, Concrete, and the Mountain. Thus, the thesis follows the structure of a walk through Clark's work, designed to echo Clark's own walking poetry. These four chapters explore different facets of Clark's influence: The Field chapter investigates Clark's reputation as a pastoralist, and his links to Romanticism, as well as to Charles Olson's open field poetics. Chapter two, 'Composition is a forgotten art': The Garden, explores Clark's engagement with 'domestic nature', and the parallels he creates between the space of the text and the space of the garden, and how this parallel allows for intense formal experimentation in a small space. Additionally, the Garden chapter investigates spaces of rest and recuperation in Clark's work. Chapter three, Thomas A. Clark and Concrete Poetry investigates Clark's relationship with concrete poetry, and how his post-concrete poetics have developed in relation to the broader post-concrete and conceptual art scene in Britain. Finally, Mountain Tasting: Zen and the poetry of Thomas A. Clark examines Clark's relationship with Japanese Zen poetics, and the way in which the 1960s interest in Zen which influenced Objective poetry and minimalism has profoundly influenced Clark's understanding of the ethical function of a text.

Clothing Darwinism : Absent Bodies

Makins, Courtney January 2019 (has links)
Garments are everywhere in today’s society and often presented on the body, although the absence of the body in design can have an integral impact on how they are perceived by an audience. An experimental material coating, aided garments to become sculptural by portraying the essence of the body. This essay argues that garments are challenged through their perception and purpose by the absence of the body, allowing the sculptures to develop a language in their own right. Through means of forming methods, absence of the body and materiality, garments are able to evolve to communicate an idea challenging one’s preconceived garment notions and broadening the spectrum of situational presentational methods.

Acquisitions: Poison Pill for Innovation?

Xu, Puwei, De Wulf, Loïc January 2010 (has links)
Nowadays, many firms are or have already been engaged in an acquisition process, either as target or acquirer. While these companies seem confident in the potential returns of such endeavors, the positive aspect of those acquisitions has yet to be proven. There is indeed a vivid discussion among scholars, which are divided into two categories. On the one hand, there are those considering acquisitions as a source of additional knowledge that will in turn increase the innovation within the company; and on the other hand, those denigrating acquisitions, assimilating them to a “poison pill” for innovation. The purpose of this research is therefore to investigate whether the acquisitions will influence positively or negatively the innovative performance of companies involved in such processes. Using a quantitative approach, this research analyzed the R&amp;D investments made by those companies and the issued patents gained in return. The research provides mixed results. While acquisitions seem to have a positive impact on the companies‟ innovative performance during the two years following the acquisition, this positive impact does not last and even becomes negative during the third year.

Marketing innovation on constructional steel bar - A Case study of H Company

Liu, Ming-Tan 15 August 2007 (has links)
Marketing not merely refers to selling, advertising, sales promotion and public relation, but also includes various perspectives which shows solid knowledge and sturdy ability. Marketing relates to corporate operation and public daily lives intensively as well. However, it is difficult for corporation to implement diversified marketing activities due to confined product features. Marketing programs are particularly restricted to narrower scopes within the boundary of market characteristic and industry common practices for conventional industry. In virtue of the price fluctuation of international steel products in recent years, how to increase market share with more innovative marketing programs is an important strategic concern of steel industries. Hence, marketing innovation has become the breakthrough point that conventional industry needs to pursuit. This study profoundly analyzes the H-company, which has carried out its traditional sales practices for more than thirty years, by literature review and case study methodology. After recognizing the target market and focusing on meeting customers¡¦ needs, we developed the innovative marketing strategies containing product, price, place and promotion aspects. Next, we integrated marketing techniques of horizontal and vertical alliances, financial instruments as well as marketing concepts. Then, by thoroughly executing ISO quality policy ¡§ pragmatic quality, customer satisfaction¡¨ which H-company has exercised to build its new competition strategies and target of growth and profit. Based on these integrated concepts, we constructed an innovative marketing model. Finally, the in-depth interviews were made to verify the feasibility of this innovative marketing model from customers¡¦ perspective. The sample comprised two direct clients and two intermediary agents, were selected from customers of H-company. The research reached the conclusions that the innovative marketing model proposed by this study has not only verified its market feasibility through clients¡¦ in-depth interview, but also modified from customer¡¦s perspective to fit customer needs. The ultimate target of the modified model is creating high customer value through high quality consistency, pricing based on customer value, forming closer partnership relationship, delivery reservation system, trustworthy business image, integrated service combining constructional reinforced steel bar forming industry or concrete industry, and marketing-finance integration service. The verification via deep customer interviews also demonstrates that the revised innovative marketing model can best approach customer needs and acquire high marketing achievements. Last but not least, the study was done in research methodology and provided some strategic implications, making up its contributions to both academic and practical aspects.

Multi-Jurisdictional Tax Incentives and the Location of Innovative Activities

MacDonald, Christy January 2009 (has links)
In this dissertation, I explore the effect of tax incentives on where U.S. multinationals decide to locate their innovative activities worldwide. Research and development (R&D) tax incentives offered by foreign countries and differences between U.S. and foreign tax rates provide opportunities that may influence where multinationals decide to locate their innovative activities. Using firm-level patenting data that identifies the country-specific location of innovations from 1986 to 2000, I examine the relation between innovative activities performed in a foreign country and these tax incentives using the Heckman (1979) two step estimation approach. I find evidence that the foreign percentage of innovative activities is associated with the attractiveness of foreign R&D tax incentives and with an increase in the effect of U.S. R&D allocation rules. In addition, the results suggest that firms in excess foreign tax credit positions decrease the amount of R&D activities in a foreign location with increased foreign tax rates, consistent with income shifting incentives. In contrast, I find that the firms in deficit foreign tax credit positions increase their foreign R&D activities with increasing foreign tax rates. This study is the first to examine and provide evidence of the influence of foreign R&D tax incentives and income shifting incentives on a U.S. multinational’s decision on where to locate R&D activities.
