Avaliação do efeito da paralisação da aeração no tratamento biológico aeróbio da água residuária da indústria de farinha de mandioca

The cassava wastewater, generated during the cassava processing, is a pollutant and toxic waste. This study compared the efficiency of the cassava wastewater treatment in three batch aerobic systems with a ru1nning time of 24 hours, and aeration stoppage of 12h with 2,500, 6,000 and 10,000 mg COD L-1 . The systems were evaluated for COD, pH, SVI and F/M. The results showed that the reactor with aeration stoppage for 12 hours, with 2,500 mg COD L-1 , presented the best reduction in a process with considerable energy consumption saving compared to traditional continuous systems.

Reestruturação recente da indústria petroquímica: análise Brasil-Mundo do processo de integração vertical

Este estudo analisa o desenvolvimento do processo de integração vertical na indústria petroquímica brasileira a partir da década de 90, focando nos determinantes para este movimento e confrontando com o mesmo processo adotado em grandes empresas mundiais da indústria

Estudo sobre eficiência energética em uma indústria de injeção plástica

The reason of this work is perform a study about using of electrical energy to identify the opportunities through rational use of electrical energy. For that it was necessary perform an analysis of hired energy against consumption. Based in a guide of energy analysis were found the main consumers and verified the main problems, which generate excessive use of electrical energy in a plastic injection factory. It was also analyzed the painting line because there are some thermal equipment that use electrical energy. Based on the data obtained will be proposed ways to reduce the needless consumption and energy use of rationally and efficiently, in addition to re-evaluate the contracted demand based on the new policy of supplying and charging.It were also proposed thermodynamics solutions to reduce the energy consumed in thermal process

Decisão making or buying: uma aplicação em células de manufatura de uma indústria de produção mecânica

In order to maintain the competitiveness the companies seek for cost reduction and resource optimization. A product or service price is calculated considering direct and indirect costs involved in its fabrication, which means that if an intern indirect process is optimized, the final price of the product is also reduced and becomes more interesting to the final costumer. Considering this reasoning, the companies must evaluate each of their processes and optimize them. It is common to outsource intern products manufacturing as a cost reduction strategy, nevertheless when there are already resources and capability to produce the own goods, it becomes necessary to evaluate the economic gain that each strategy - make or buy - generates. This paper aims to evaluate the necessary support to take a decision regarding making or buying in a production cell of hoses based in the value of economic cost, system cost and decision process

Técnicas de caracterização microestrutural, por microscopia óptica e microscopia eletrônica de varredura, de aços bifásicos e multifásicos aplicados à indústria automobilística

This project developed microstructural characterization technics of commercial dualphase and multi-phasic (TRIP) steels that were provided by the automotive industry and are currently used as the raw material for the production of automobiles. Inserted in this context, there is the development of the advanced high strength steels in consonance with the ULSABAVC project, which aims the production of safe, economically viable and efficient in terms of fuel consumption vehicles for the 21st century. The micro-structural characterization of biphasic and multiphase steels was done by the identification and quantification of the coexistent phases. In this item, a special attention was given to the technics that were performed using optic microscopy and scanning electron microscopy. An important contribution to this work was the utilization of different alternative chemical reagents (Beraha, Heat-Tinting technics) in addition to the classical ones (Nital and LePera)already used conventionally by the UNESP's Group of Mechanical, Microstructural and Fractografic Characterization of Materials. The revealed microstructures were correlated with the materials' mechanical properties determined through traction tests, such as ultimate tensile strengths, yield strength and stretching important since the material has structural application in the automotive industry. As a result, it was observed the superiority concerning the studied mechanical properties for the biphasic and multiphasic steels when compared to the conventional carbon steels. Besides, it was perceived a large potential for the industrial scale utilization of the Heat Tinting technics in this field, seen its differentiation of the existent phases and easy reproducibility

A indústria criativa de games no Brasil

The games are a worldwide fever, since 80's is becoming more popular and featured in the media, in the culture and economy. The sector fits in creative economy, a sector of economy that is growing gaining prominence for being a driver for economic, cultural and environmental development. The producing process, competition and logic of cultural games industry differ from traditional economy. The article seeks to show what is necessary to the game industry be able to establish and remain on the market, and what is the obstacles that this industry will face in Brazil, a potential creative economy country

A indústria farmacêutica no Brasil: um estudo do impacto socioeconômico dos medicamentos genéricos

Recently, some countries outside the Triad (Japan, Europe and the United States) have assumed an important role in the pharmaceutical scenario, as large producers, among them stand out Brazil. In the 90s, there were major institutional transformations and the pharmaceutical industry has undergone a reverse specialization process, because liberalization has discouraged production of pharmaceutical chemicals and dependence of imports increased. The law of generics medicines in 1999 emerged as an attempt to increase the population's access to medicines equivalent to ones with brand, with more affordable prices. As a result of this law there was a strengthening of the national capital and a major attraction for foreign companies to brazilian market. This study aims to assess the development trajectory of the country, showing how path-dependence has culminated in greater empowerment of national pharmaceutical industries after the Generics Law in 1999

Estratégias Produtivas e Tecnológicas das empresas da Indústria Farmacêutica do Brasil e da Índia: um exame a partir de indicadores aplicados aos fluxos de comércio exterior

This work aims to evaluate the different trajectories in terms of production structure, technological capabilities and performance in international trade of pharmaceutical industries in Brazil and India. For this, we build international trade indicators, based on data provided by the COMTRADE, the UN database for trade. Through the indicators, it is observed that the countries have different results in the catch-up process of the pharmaceutical industry. India has built a productive structure strongly based on generic drugs, with which it is able to greatly meet domestic demand and export to many countries worldwide. Brazil remains in a position of dependence of foreign production, with a high level of imports and exports to the region of Latin America
