A arquitetura jurídico-institucional de um ambiente de inovação brasileiro: o Parque Tecnológico de São José dos Campos.

O presente trabalho objetiva investigar a arquitetura jurídico-institucional de um ambiente inovativo denominado parque tecnológico. Este é um arranjo imobiliário que conta com os elementos da chamada tríplice hélice - academia, setor privado e Estado. Almeja a transformação do conhecimento em desenvolvimento, por meio de atividades fundadas em ciência, tecnologia e inovação (C&T&I). A pretensão é contribuir com a premissa de que esses arranjos são frutos da nova lógica econômica baseada no conhecimento e da atual concepção sistêmica de inovação que exige interdependência e interação dos seus agentes. Dentre esses destacamos, o Estado, por ser o ator mais paciente por resultados e o potencial idealizador, fomentador e articulador de processos inovativos sistemicamente pensados. A estratégia Estudo de Caso Único foi eleita para observar, em detalhes, a arquitetura jurídico-institucional do Parque Tecnológico de São José dos Campos, bem como para, a partir de um olhar jurídico-institucional, retirar aprendizados dessa experiência que possam ser aproveitados em novas modelagens de parques tecnológicos e de políticas públicas que focam a estruturação de ambientes inovativos sistêmicos. Foram priorizados exames qualitativos: (i) da sua fisiologia jurídico-institucional; (ii) dos agentes envolvidos e das respectivas amarrações jurídicas estabelecidas; (iii) da influência do Estado e das políticas públicas que o permeiam; (iv) do seu processo de implantação e desenvolvimento; e (v) dos desafios jurídico-formais e jurídico-institucionais que enfrenta. Compreendeu-se que parques tecnológicos são estruturados como arranjos híbridos, segundo a lógica da inovação em sistema, em que os elementos da tríplice hélice atuam em sinergia a partir da ativa atuação do Estado. Sua arquitetura jurídico-institucional decorre da aplicação de tecnologias de contratação e de regulação aplicadas em ambientes alicerçados em fatores institucionais específicos.

Encaminhamento óptimo do tráfego em redes Triple Play

A Internet é responsável pelo surgimento de um novo paradigma de televisão – IPTV (Televisão sobre IP). Este serviço distingue-se de outros modelos de televisão, pois permite aos utilizadores um elevado grau de interactividade, com um controlo personalizado sobre os conteúdos a que pretende assistir. Possibilita ainda a oferta de um número ilimitado de canais, bem como o acesso a conteúdos de Vídeo on Demand (VoD). O IPTV apresenta diversas funcionalidades suportadas por uma arquitectura complexa e uma rede convergente que serve de integração a serviços de voz, dados e vídeo. A tecnologia IPTV explora ao máximo as características da Internet, com a utilização de mecanismos de Qualidade de Serviço. Surge ainda como uma revolução dentro do panorama televisivo, abrindo portas a novos investimentos por parte das empresas de telecomunicações. A Internet também permite fazer chamadas telefónicas sobre a rede IP. Este serviço é denominado VoIP (Voz sobre IP) e encontra-se em funcionamento já há algum tempo. Desta forma surge a oportunidade de poder oferecer ao consumidor final, um serviço que inclua os serviços de Internet, de VoIP e de IPTV denominado serviço Triple Play. O serviço Triple Play veio obrigar a revisão de toda a rede de transporte de forma a preparar a mesma para suportar este serviço de uma forma eficiente (QoS), resiliente (recuperação de falhas) e optimizado (Engenharia de tráfego). Em redes de telecomunicações, tanto a quebra de uma ligação como a congestão nas redes pode interferir nos serviços oferecidos aos consumidores finais. Mecanismos de sobrevivência são aplicados de forma a garantir a continuidade do serviço mesmo na ocorrência de uma falha. O objectivo desta dissertação é propor uma solução de uma arquitectura de rede capaz de suportar o serviço Triple Play de uma forma eficiente, resiliente e optimizada através de um encaminhamento óptimo ou quase óptimo. No âmbito deste trabalho, é realizada a análise do impacto das estratégias de encaminhamento que garantem a eficiência, sobrevivência e optimização das redes IP existentes, bem como é determinado o número limite de clientes permitido numa situação de pico de uma dada rede. Neste trabalho foram abordados os conceitos de Serviços Triple Play, Redes de Acesso, Redes Núcleo, Qualidade de Serviço, MPLS (Multi-Protocolo Label Switching), Engenharia de Tráfego e Recuperação de falhas. As conclusões obtidas das simulações efectuadas através do simulador de rede NS-2.33 (Network Simulator versão 2.33) serviram para propor a solução da arquitectura de uma rede capaz de suportar o serviço Triple Play de uma forma eficiente, resiliente e optimizada.

Sustentabilidade das empresas associadas à REDEPETRO-RN

The present study investigated the management of social, environmental and economic sustainability practices employed by 72 oil companies in Rio Grande do Norte state in Brazil associated to Joint Business Network for Enhancing the Competitive Ability of Suppliers of Goods and Services to the Gas and Oil Industry in Rio Grande do Norte (REDEPETRO-RN). Thus, our investigation aimed to determine the extent to which sustainability practices of companies associated to REDEPETRO-RN are developed through their own efforts or influenced by the Triple Helix interorganizational arrangement (governamental organizations, education and research institutions, and industries). The research instrument used was a questionnaire in order to map and characterize the sustainability practices. The research subjects were business owners and managers. The data collected supported the descriptive, correspondence and correlation analyzes. Were identified a greater emphasis of the companies surveyed in developing sustainability practices and greater economic influence of business organizations in the construction of sustainability status. It was concluded with confirmation of thesis of the REDEPETRO-RN arrangement exhibits the characteristics and functioning of a common Interorganizational Cooperative Arrangement, not those of a triple helix interorganizational arrangement, given that the influences exerted for the development of social, environmental and economical sustainability on the part of teaching and research institutions, and government and business organizations do not interact with one another sufficiently to create a virtuous circle of cooperation among the associated companies. By contrast, the Interorganizational Cooperative Arrangement plays an important role in strengthening the competitiveness of companies affiliated to REDEPETRO-RN, by combining different competencies in an attempt at supporting the adoption of sustainability practices, a role reinforced by the scope of PETROBRAS, which, due to its economic importance, has considerable weight in the managerial decisions of associated companies

Provas de carga estática com carregamento lateral em estacas escavadas hélice contínua e cravadas metálicas em areia

An experimental study has been conducted to investigate the behavior of continuous flight auger (cfa) bored piles and metalic driven H-section piles under lateral loading in cohesionless soils. The piles were tested in two different areas at the same site. Both areas consisted of a 3-m thick compacted superficial fill of pure fine sand, underlain by layers of naturally occurring pure fine-thick sand. Fills are differentiated by the relative densities which were compressed, 45% e 70%, respectively. Each area received one identical pair of cfa piles and two identical pairs of H-piles. A static lateral loading test was performed in each pair of piles. In this work, the pile load test results are reported and interpreted. The horizontal coefficient of subgrade reaction was determined from the results of the loading tests and compared with values determined by correlations based on penetration resistance index of SPT tests (NSPT). p-y formulations describing the static behavior of the piles were applied to the problem under evaluation. Back Analyses were made through theoretical and experimental p-y curves for obtaining input parameters for the analytic models, among which the coefficient of horizontal reaction. The soil pile system horizontal loading at rupture was determined by the theoretical methods and the results were compared with the experimental results, checking its validity

Avaliação da interação universidade - empresas - governo no desenvolvimento de projetos inovadores no RN por micro e pequenas empresas

Knowledge and innovation were seen as major forces, both for survival, as the acquisition of competitive advantages in the Brazilian economy, as well as adding value to the product as a market differentiator. The Triple Helix model is directed toward the knowledge-based economy. Over the past six years, the Federal Government through the Financier of Studies and Projects ( FINEP ) invested in technological innovation projects, economic subsidies, about U.S. $ 1 billion supporting more than 800 projects with these resources. According to the MCTI , the Northeast, over the years 2000 to 2010 increased spending on Science and Technology (considering the activities of research and development more scientific and related activities) of the State Government in relation to its total revenue In 2000, 0.51% of total revenues were invested in Science & Technology, while in 2010 this figure increased to 1.31%. Among the nine Northeast states, Paraíba is highlighted. In 2000, 0.33% of its total revenues were directed to innovation, reaching 2.04% in 2010, the largest increase in the region while the RN invested 0.24% in 2000 and in 2010 reached the level of 1.42 %. According to IBGE, in the period 2000-2011, the micro and small enterprises surpassed the barrier of 6 million establishments. In 2000, there were 4.2 million establishments while in 2011 were 6.3 million active establishments. Therefore, throughout the period, there was a creation of approximately 2.1 million new establishments. Between 2000 and 2011, micro and small businesses have created 7.0 million formal jobs, 8.6 million jobs in 2000 to 15.6 million in 2011. This scenario shows the importance of this study in relation to the investment of governments in RD & I in micro and small enterprises. This study aims to analyze the interaction Universities - Business - Government in the development of innovation in micro and small companies in Rio Grande do Norte participants of the edicts of Inova FAPERN. We chose to adopt as a research method case study concerning the procedure of the research, exploratory, descriptive, and on documents with engineers and researchers of innovation projects approved by PAPPE Subsidy (Inova -RN I, II and III). Data collection was done through the report made by FAPERN entitled: " Evaluation of companies financed and supported by the Grant Program for Technological Innovation for Micro and Small Enterprises RN - INOVA -RN " (2010) and a questionnaire with 40 closed questions and 1 opened to 30 affirmative composed based on a 5-point Likert scale. The analysis of data was qualitative and quantitative. The study provided to identify the importance and barriers arising from the relation between Government Enterprise (micro and small) and University as essential to the economic development of the region. It was also identified that, in the innovation projects, 70% of the goods or services originating from research were to market these, 50% resulted in a patent for the company and 80% publications of scientific articles

Triple bothropic envenomation in horses caused by a single snake

In the present study, snakebites caused by a single Bothrops pauloensis simultaneously affecting three male adult horses are described. Whereas the first two affected horses were six years old, the third was 16 years old; they weighed respectively 555, 550 and 500 kg. All horses presented swollen muzzles. The first animal received an initial antivenom dose of 19 vials and adjuvant medication, it was also subjected to tracheostomy due to the progression of acute respiratory failure. The second and third horses respectively received 15 vials of antivenom each, in addition to adjuvant medication. Due to continuous changes in blood coagulation observed during hospitalization, the first and the second horses received five more vials of antivenom, respectively, in the second and third days of treatment. The first animal was discharged on 15(th) day and the other on the 8(th) day of hospitalization. Several factors including the main actions of Bothrops venom (coagulation, proteolytic and vasculotoxic activities), the importance of early diagnosis based on clinical history and clinical examination suggesting the diagnosis of Bothrops snakebite, the adequate doses of antivenom, and finally the immediate tracheostomy are herein discussed. The tracheostomy, required to save the life of the first horse, should only occur after the administration of antivenom and control measures for changes in blood coagulation.

Indirect constraints on the triple gauge boson couplings from Z -> b(b)over-bar partial width: An update

We update the indirect bounds on anomalous triple gauge couplings coming from the non-universal one-loop contributions to the Z --> width. These bounds, which are independent of the Higgs boson mass, are in agreement with the standard model predictions for the gauge boson self-couplings since the present value of R-b agrees fairly well with the theoretical estimates. Moreover, these indirect constraints on Delta g(1)(Z) and g(5)(Z) are most stringent than the present direct bounds on these quantities, while the indirect limit on lambda(Z) is weaker than the available experimental data.

Triple photon production at the Tevatron in technicolor models

We study the process p (p) over bar --> gammagammagamma as a signal for associated photon-technipion production at the Tevatron. This is a clean signature with relatively low background. Resonant and non-resonant contributions are included and we show that technicolor models can be effectively probed in this mode. (C) 2002 Elsevier B.V. B.V. All rights reserved.

TRIPLE-VECTOR-BOSON PROCESSES IN GAMMA-GAMMA COLLIDERS

We study the production of three gauge bosons (W(+)W(-)Z(0) and W(+)W(-)gamma) at the next generation of linear e(+)e(-) colliders operating in the yy mode. We analyze the total cross sections as well as several kinematical distributions of the final state particles. We find out that a linear e(+)e(-) machine operating in the rr mode will produce 5-10 times more three-gauge-boson states compared to the standard e(+)e(-) mode at high energies.
