Esta dissertação é um estudo de caso sobre aprendizagem tecnológica que, considerando as evidências empíricas descritas no Capítulo 6 e à luz da Tabela 3.1, procurou identificar a trajetória de acumulação de competência tecnológica da Enxuta Industrial Ltda., ao longo do período estudado (1980 - 2000), para as funções tecnológicas de investimentos (decisão e controle sobre a planta e engenharia de projetos), de processos e organização da produção, de produtos e de equipamentos. Para construir a estrutura de competências tecnológicas para a indústria de eletrodomésticos foi utilizada a estrutura desenvolvida por Figueiredo (2000). Por outro lado, considerando as evidências empíricas descritas no Capítulo 7 e à luz da Tabela 3.2, procurou-se identificar a influência dos processos de aprendizagem utilizados pela empresa sobre a sua trajetória de acumulação de competência tecnológica. Os processos de aprendizagem são avaliados à luz de quatro características chave: variedade, intensidade, funcionamento e interação, a partir do uso da estrutura desenvolvida por Figueiredo (2000). Este estudo verificou que o modo e a velocidade de acumulação de competência tecnológica na Enxuta Industrial Ltda. foram influenciados pelos processos e mecanismos de aprendizagem usados para adquirir conhecimento tecnológico e convertê-lo em organizacional. Estes processos e mecanismos de aprendizagem propiciaram a empresa alcançar uma maior velocidade na acumulação de capacidades tecnológicas, quando de sua entrada na indústria de eletrodomésticos, o que proporcionou alcançar o desenvolvimento tecnológico necessário para atuar nesta indústria. Porém, a simples incidência desses processos na empresa não garantiu uma implicação positiva para a acumulação de competência tecnológica. Pois, no período de 1991 - 1995, verificou-se a deterioração do funcionamento dos processos de aprendizagem utilizados na empresa, o que pode ter influenciada negativamente a repetibilidade e a interação daqueles processos. Isto parece ter contribuído para que a empresa falhasse em construir e acumular competências tecnológicas inovadoras naquele período. Através do uso de estrutura existente na literatura, aplicada a uma indústria diferente de estudos anteriores, esta dissertação sugere que deve existir um esforço organizado, contínuo e integrado para a geração e disseminação de conhecimento tecnológico na empresa, o que pode acelerar a acumulação de competências tecnológicas, desta forma propiciando à empresa a construção de uma trajetória de aproximação da fronteira de desenvolvimento tecnológica da indústria.

A presente dissertação trata da estruturação de um cluster de economia criativa no centro da cidade de São Paulo, voltado à área de tecnologia. A escolha da região central, assim como da economia criativa como impulso para a requalificação econômica e reocupação social da área, tem como objetivo enfrentar o problema do esvaziamento do centro da cidade, impulsionando o empreendedorismo e o posicionamento da região como local de convivência. Para análise da viabilidade e adequabilidade dessa proposta optou-se por uma pesquisa aplicada, cujos procedimentos englobaram uma breve revisão da literatura e também entrevistas com profissionais do setor criativo. Foram realizados estudos de casos internacionais e nacionais; estudo da legislação brasileira; avaliação do nível de desenvolvimento dos setores criativos em São Paulo e reflexão sobre as vocações da cidade. Com essa bagagem, iniciou-se a modelagem do cluster de tecnologia do Distrito Criativo da Sé/República, por meio da qual se objetivou traçar propostas de ações que pudessem ser desenvolvidas em curto, médio e longo prazos. Foram apresentadas ações mais imediatas, como a realização de um branding das atividades já em andamento, medidas realizáveis no médio prazo, como a concretização de parcerias, e outras um tanto mais estruturantes, como a requalificação de espaços e de projetos. Todas essas medidas almejam otimizar a ação municipal na busca pela reocupação da região e, consequentemente, na atração de investimentos para o local, de modo a frear o processo de degradação e alavancar o processo de reposicionamento do centro da cidade de São Paulo como valioso núcleo econômico e cultural para o Município. Com o presente trabalho, chega-se à conclusão de que há exemplos no Brasil e no mundo que podem servir de inspiração para o desenvolvimento da ação proposta e que a possibilidade de se gerar um impacto positivo, mesmo em épocas de dificuldades orçamentárias, é bastante plausível.

Textile production has been considered as an activity of high environmental impact due to the generation of large volumes of waste water with high load of organic compounds and strongly colored effluents, toxic and difficult biodegradability. This thesis deals with obtaining porous alumina ceramic membranes for filtration of textile effluent in the removal of contaminants, mainly color and turbidity. Two types of alumina with different particle sizes as a basis for the preparation of formulation for mass production of ceramic samples and membranes. The technological properties of the samples were evaluated after using sintering conditions: 1,350ºC-2H, 1,450ºC-30M, 1,450ºC-2H, 1,475ºC-30M and 1,475ºC-2H. The sintered samples were characterized by XRD, XRF, AG, TG, DSC, DL, AA, MEA, RL, MRF-3P, SEM and Intrusion Porosimetry by Mercury. After the characterization, a standard membrane was selected with their respective sintering condition for the filterability tests. The effluent was provided by a local Textile Industry and characterized at the entry and exit of the treatment plant. A statistical analysis was used to study the effluent using the following parameters: pH, temperature, EC, SS, SD, oil and grease, turbidity, COD, DO, total phosphorus, chlorides, phenols, metals and fecal coliform. The filtered effluent was evaluated by using the same parameters. These results demonstrate that the feasibility of the use of porous alumina ceramic membranes for removing contaminants from textile effluent with improved average pore size of 0.4 micrometre (distribution range varying from 0,025 to 2.0 micrometre), with total porosity of 29.66%, and average percentages of color removal efficiency of 89.02%, 92.49% of SS, turbidity of 94.55%, metals 2.70% (manganese) to 71.52% (iron) according to each metal and COD removal of 72.80%

The advantage in using vegetable fibres in place of synthetic fibres such as glass fibre, for reinforcements in composites are: biodegradability, low cost, low density, good tenacity, good thermal properties, low energy content and reduced use of instruments for its treatment or processing. Even though, problems related to low mechanical performance of some of the natural fibres, has caused difficulty in their direct application in structural elements. The use of alternative materials like hybrid composites has been encouraged, thus trying to better the structural performance of the composites with natural fibres. This work presents a comparative study of the strength and stiffness of hybrid composites with orthopthalic polyester matrix reinforced with E-fibre glass, jute and curauá. The experimental part includes uniaxial tension and three point bending tests to determine the mechanical properties of the final product. The hybrid composite was manufactured in a local industry and was in the form of laminates. All the samples were projected to withstand the possible structural applications as reservoirs and pipes. CH (laminated hybrid composite with glass and curauá fibres). The results obtained show clearly the influence of the hybridization in all the types tested and indicate a good mechanical performance of the composite with glass/curauá fibres in relation to the composite with glass fibres. Aspects in relation to the interfaces glass/curauá composites besides the fracture characteristics for all loading types were also analysed

The industries of structural ceramics are among the most important production chains in the state of Rio Grande do Norte. The industry and other interest groups to target the replacement of firewood by natural gas. Studies accordingly concluded that simple change does not guarantee products of superior quality, and that the increase in spending on fuel can economically cripple the use of gas for burning the majority of products manufactured by that action. However some proposals of innovations in terms of process and product are being studied in an attempt to justify the use of natural gas in industry, structural ceramics. One of the aspects investigated is the development of ceramic products differentiated, with new designs and greater value added. Inserted in that context, this paper aims to investigate the potential use of clay-firing clear fabrication of the "bricks of apparent joins drought", a new ceramic product with an innovative way. The development of the work was done in three stages. In the initial stage was held the characterization of raw materials, sought information on physical, chemical, mineralogical and mechanical samples. In the second stage five bodies were made using two of the nine ceramic clay characterized the first step. The masses were analyzed and compared with respect to the size distribution, plasticity and technological properties. In the last part of this work was carried out tests on massive bricks manufactured on an industrial scale. The results show that the nine clays can be used in the manufacture of new ceramic products, is the only constituent of mass ceramic or by mixing with other(s) clay(s

The manufacture of prostheses for lower limb amputees (transfemural and transtibial) requires the preparation of a cartridge with appropriate and custom fit to the profile of each patient. The traditional process to the patients, mainly in public hospitals in Brazil, begins with the completion of a form where types of equipment, plugins, measures, levels of amputation etc. are identified. Currently, such work is carried out manually using a common metric tape and caliper of wood to take the measures of the stump, featuring a very rudimentary, and with a high degree of uncertainty geometry of the final product. To address this problem, it was necessary to act in two simultaneously and correlated directions. Originally, it was developed an integrated tool for viewing 3D CAD for transfemoral types of prostheses and transtibial called OrtoCAD I. At the same time, it was necessary to design and build a reader Mechanical equipment (sort of three-dimensional scanner simplified) able to obtain, automatically and with accuracy, the geometric information of either of the stump or the healthy leg. The methodology includes the application of concepts of reverse engineering to computationally generate the representation of the stump and/or the reverse image of the healthy member. The materials used in the manufacturing of prostheses nor always obey to a technical scientific criteria, because, if by one way it meets the criteria of resistance, by the other, it brings serious problems mainly due to excess of weight. This causes to the user various disorders due to lack of conformity. That problem was addressed with the creation of a hybrid composite material for the manufacture of cartridges of prostheses. Using the Reader Fitter and OrtoCAD, the new composite material, which aggregates the mechanical properties of strength and rigidity on important parameters such as low weight and low cost, it can be defined in its better way. Besides, it brings a reduction of up steps in the current processes of manufacturing or even the feasibility of using new processes, in the industries, in order to obtain the prostheses. In this sense, the hybridization of the composite with the combination of natural and synthetic fibers can be a viable solution to the challenges offered above
