Estratégias tecnológicas em transformação: um estudo da indústria farmacêutica brasileira

The aim of this research is to analyze the extension of changes in technological strategies of a group of Brazilian pharmaceutical companies, which we believe were induced by transformations in the institutional environment during the 1990s. Major institutional changes, such as the enacting of laws that recognized drug patents rights and fostered generic drugs market, have strengthened the market insertion and competitive position of these companies, what would enable an increase in research and development efforts in Brazil. In addition to the literature on technology strategy and drug industry, this study was based on interviews with six Brazilian pharmaceutical companies, all of which were ranked among the top national companies in the industry and have been considered in previous studies particularly active in the process of changing technological strategies. This research confirmed a significant intensification of technology efforts carried out by Brazilian drug companies. Nevertheless, the R&D intensity is still far below the global pattern and innovative impacts are slight.

Utilização de trocadores de calor de placas em espiral em processos da indústria siderúrgica

Stricter environmental policies are shown necessary to ensure an effective pollutant emission control. It is expected for the present year of 2015, that Brazil will assume, at the 21th United Nation's Climate Change Conference (COP21), implementation of commitment to a low carbon economy. This positioning affects the industrial environment, so that is deemed necessary to search for new technologies, less aggressive to the environment, so the adequacies to the new emission policies do not cause a negative effect on production. Almost all of the processes performed in the steel industry demand burning fuel and, therefore, flue gases are sent to the atmosphere. In this present work is discussed the utilization of heat exchangers so, by recovering part of the available heat from the flue gases of certain industrial process, the combustion air is preheated. The combustion air preheat results in less energy requirement, i.e., less need of fuel consumption and, in addition, minor amount of pollutants to be emitted. Due to better fitting to the process, it is studied the utilization of spiral plate heat exchangers. The heat exchanger dimensioning is made by an iterative method implemented in the software Microsoft Excel. Subsequently are analyzed the gains in terms of process's thermal efficiency improvement and the percentage of fuel saving. The latter implies in reduction of the same percentage of greenhouse gases emission

Avaliação da variação sedimentológica em uma área da plataforma continental sob a atuação da indústria petrolífera

Petroleum exploration activity occurs on the offshore Potiguar Basin, from very shallow (2-3 m) until about 50 m water depth, extending from Alto de Touros (RN) to Alto de Fortaleza (CE). Take in account the biological importance and the heterogeneity of sediments on this area, it is necessary the understanding of the sedimentological dynamics, and mainly the changes generated by petroleum exploration to prevent possible damages to environment. Despite the intense activity of oil exploration in this area, research projects like these are still rare. In view to minimize this gap, this study was developed to evaluate sedimentological, mineralogical and geochemical changes in the vicinity of a exploration well, here designated as well A, located on the Middle continental shelf, near the transition to Outer shelf. The well selected for this study was the first one drilled with Riserless Mud Recovery technology (RMR) in Brazil. The main difference from this to the conventional method is the possibility of drilling phase I of the well with return of drilling material to the rig tank, minimizing fluid and gravel discharging around the vicinity, during this phase. Monitoring consisted of three surveys, first of them done before start drilling, the second one done 19 days after the end of drilling and the third one done one year after then. Comparison of the studied variables (calcium carbonate and organic matter content, sediment size, mineralogy and geochemistry) was done with their average, median and coefficient of variation values to understand the changes after drilling activity. Because operating company technical reasons, the well location was changed after the first survey (C1), resulting in a shift of the sampled area on the two last surveys (C2 e C3). Nevertheless, the acquired data presented a good correlation, with no loss to the mean goal of the study. The sedimentological, mineralogical and geochemical analyzes were done at Federal University of Rio Grande do Norte (UFRN). The results indicated a predominantly sandy environment along the three surveys. It was noticed that the first survey (C1), presented different values for all the studied variables than to the second (C2) and third (C3) surveys, which had similar values. Siliciclastic sediments are prevalent at all surveys, and quartz is the main component (more than 80%). Heavy minerals (garnet, turmaline, zircon and lmenite), rock fragments and mud aggregates also was described. Bioclastic sediments are dominated by coralline algae (more than 45%) and mollusks (more than 30%), followed by benthic foraminifera, bryozoans and worm tubes. More rarely was observed ostracoda and spike of calcareous sponge. Because the low changes of the sediments at the studied area and by the using of RMR method in the drilling, it was possible to conclude that drilling activity did not promote significant alteration on the local sediment cover. Changes in the studied variables before and after drilling activity could be influenced by the changing in the sampling area after survey 1 (C1).

Avaliação da fertilização azotada na produtividade e qualidade da variedade Hermes para indústria

O azoto é determinante na produtividade e na qualidade da batata para indústria. Com este trabalho pretendeu-se avaliar o efeito de diferentes doses de azoto na variedade de batata “Hermes”, em plena condições de cultivo do Vale do Tejo. Os tratamentos consistiram na aplicação de 0 (N0), 80 (N80), 160 (N160), 240 (N240) e 320 (N320) kg de azoto/ha, na forma de ENTECÒ 26. O ensaio foi instalado em parcelas totalmente aleatórias, com 4 repetições. Foi registado semanal a taxa de cobertura de solo pelo método da grelha até à sua cobertura total. Bissemanalmente, foram recolhidas plantas nos tratamentos N0 (0kgN/ha) e N160 (160kgN/ha) para avaliação do seu desenvolvimento e crescimento. No final do ciclo cultural avaliou-se a produção total, comercial, em peso e número de tubérculos. Avaliou-se ainda o peso específico, os teores em matéria seca dos tubérculos e a percentagem do azoto total na matéria seca das folhas e tubérculos. A adubação azotada influenciou a dimensão do aparelho fotossintético, através do estímulo de ramificações. Verificou-se uma maior produtividade de tubérculos nos tratamentos com maior aplicação de azoto, embora os acréscimos tenham sido menores a partir dos 160kg/ha. O azoto influenciou a percentagem de tubérculos de maior calibre.

Metáforas del amor en la poesía de la Grecia antigua (I): la épica y la lírica arcaicas

Partiendo del concepto de metáfora cognitiva, que complementa al más conocido de metáfora literaria, y analizando la base conceptual que a ambas subyace, pretendemos un cuidadoso análisis de los textos de poesía épica y lírica arcaicas, sin olvidar la importancia fundamental del contexto cultural en que estos surgen, para obtener una mejor comprensión de la forma en que los griegos conceptualizaban el sentimiento amoroso.

Apoio governamental à inovação tecnológica: análise da indústria farmacêutica paraense

The transformations economical, cultural and social that happen in world ambit they are associated to the intense progress and expansion of new technologies, forcing governments, people, companies and nations to the introduction of new patterns of behavior, forcing, in that way, to the continuous renewal of products and technological processes to maintain the competitiveness, so much among nations, as in the managerial world. In that matter, the technological innovation is recognized as basic factor of maintainable economical competitiveness, being the responsible for the breaking and/or improvement of the techniques and production processes, what presupposes the systematization varied institutional arrangements that they involve firms, interaction nets among companies, government agencies, universities, research institutes, laboratories of companies and scientists and engineers activities. Those arrangements, to the if they articulate with the educational system, with the industrial and managerial section and, also, with the financial institutions, they take the form that Freeman (1987) it coined of national system of innovation, promoted through public politics of CT&I, which seek to induce and to support innovative initiatives in the companies, as well as to establish demands and to prioritize vocations and regional potentialities. In that context of government support to the technological innovation interferes this study, that it looked for to know the reasons of the fragility innovative in the pharmaceutical industry of State of Pará in Brazil, pointed for PINTEC (2005), starting from the point of view of the businessmen of that section. For such, the qualitative approach was used - with interviews directing semi and the technique of the content analysis. The results of the research pointed that the fragilities innovative of the section links to the ignorance of the government support to the technological innovation on the part of the businessmen of the pharmaceutical industry of State of Pará in Brazil

Teor de sal e de gordura em refeições prontas a comer

Introdução: Os consumidores estão cada vez mais exigentes e conscientes do impacto na saúde do consumo de determinados alimentos. O estilo de vida das famílias tem sofrido alterações profundas, traduzindo-se essencialmente na falta de tempo para preparar as refeições. Por esse motivo, recorrem cada vez mais à aquisição de alimentos confecionados ou pré-confecionados. Objetivos: Determinar os teores totais de sal e de gordura de refeições prontas a comer, e avaliar os benefícios/riscos para a saúde da população Portuguesa, tendo por base as recomendações de referência e o consumo destes produtos. Métodos: Foram adquiridas, em 2015, em grandes superfícies da região de Lisboa, 24 refeições prontas a comer, sendo 12 fornecidas por cadeias de fast-food. O teor de sal foi determinado utilizando o método de Charpentier-Volhard. O teor de gordura total foi determinado pelo método de hidrólise ácida, seguido de extração em Soxhlet com éter de petróleo. Os valores obtidos foram comparados com os valores de referência do Regulamento (UE) N.º 1169/2011 e com as orientações da Organização Mundial de Saúde. Resultados: O teor de gordura total das refeições analisadas variou entre 9,70 g/porção (dobrada com feijão branco) e 69,3 g/porção (hambúrguer de carne de vaca com batata frita). Em 75% das refeições analisadas o teor de sal foi superior a 2,5 g/porção, representando mais de 50% da dose diária de referência para o consumo de sal. De uma forma geral, o teor de sal era inferior nas refeições de fast-food comparativamente às outras refeições analisadas. Conclusões: Grande parte das refeições analisadas apresenta um elevado teor de gordura e de sal. Parece recomendável a sua reformulação, no sentido de se tornarem produtos mais saudáveis, promovendo a saúde pública. Num futuro próximo, pretende-se alargar este trabalho de investigação a um maior número de refeições.
