Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Capacidade antioxidante do suco de laranja fresco versus pasteurizado no sangue de indivíduos adultos

O suco de laranja é um alimento rico em substâncias antioxidantes, como os flavonoides cítricos, vitamina C e carotenoides, que podem reduzir o estresse oxidativo que está relacionado à gênese das doenças cardiovasculares, diabetes e câncer. No entanto, o processamento da laranja para obtenção do suco interfere no tipo e quantidade dos compostos antioxidantes, podendo comprometer as ações esperadas. O objetivo deste trabalho foi avaliar a atividade antioxidante do suco de laranja, comparando os resultados após a ingestão aguda do suco de laranja fresco e do suco de laranja pasteurizado comercialmente em indivíduos adultos saudáveis. Cada voluntário foi submetido a dois tratamentos: ingestão aguda de suco de laranja fresco e, após intervalo de 30 dias, ingestão aguda de suco de laranja pasteurizado. Nos dois tratamentos foram colhidas amostras de sangue dos indivíduos antes e após a ingestão do suco de laranja. O efeito antioxidante total foi mensurado pelo ensaio do radical ABTS+ (2,2'azinobis (3-etilbenzenotiazolina 6-sulfônico) e pelo ensaio de TBARS (substâncias reativas ao ácido tiobarbitúrico) nas amostras de sangue. Observou-se um aumento de 2,2% na capacidade antioxidante do sangue a partir de 4 horas após a ingestão do suco de laranja fresco e que se manteve estável até 24 horas do consumo (p<0.05). Já com a ingestão do suco de laranja pasteurizado, a capacidade antioxidante se manteve estável e equivalente ao suco de laranja fresco nas primeiras 4 horas, mas aumentou 1,4% após 8 horas, permanecendo neste nível até as 24 horas seguintes (p<0.05). Após a ingestão do suco fresco, os níveis de peroxidação lipídica, diminuíram 27% nas primeiras 4 horas. Porém, a partir das 8 h retornaram ao valor inicial. Os resultados após o consumo do suco pasteurizado mostraram uma redução da peroxidação lipídica em 18% a partir das 4 horas e 8 h (p<0.05), e esta redução se acentuou (27%) às 24 h ...

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

Utilização de alambique de aço inoxidável na produção de aguardente de líquor de laranja: efeito na formação de carbamato de etila

O Brasil é reconhecido mundialmente como o maior produtor e exportador de suco de laranja do mundo. O líquor de laranja é um dos principais subprodutos da indústria cítrica, rico em açúcares e destinado, quase que exclusivamente para a produção de ração animal, já que seu descarte certamente causaria problemas ambientais. Com o intuito de ter um melhor aproveitamento deste subproduto, foi desenvolvido um novo tipo de destilado obtido a partir da fermentação do líquor de laranja. Dado o enorme volume de líquor e considerando-se também o enorme volume de fermento de descarte da indústria cervejeira (160 milhões de litros/ano) ainda viável, está sendo objeto de estudo a utilização deste fermento na obtenção da aguardente de líquor de laranja. Nesse sentido, foram obtidas amostras de aguardente de líquor de laranja, utilizando-se de técnicas tradicionais de produção de cachaça, sendo o líquor fermentado de fermento que é descarte da indústria cervejeira. Dessa forma, foram avaliados a viabilidade da levedura de descarte da indústria cervejeira, o teor de sólidos solúveis, o teor de cobre e carbamato de etila na aguardente de líquor de laranja obtida utilizando alambique de aço inoxidável.

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

Mudanças estruturais nas cadeias de valor na indústria do vestuário: um estudo de caso

In the early 1990 Gary Gereffi and Miguel Korzeniewicz published the book Commodity Chains and Global Capitalism. In the two decades prior to the publication, industrialization worldwide, had undergone significant changes, made more segmented and dispersed in certain regions. In the book, the authors produce a new set of categories to analyze the new standards for establishment and operation of global value chains, their organization, the new geography of manufacturing and the role of the countries in this scenario. Today, in the middle of the second decade of this century, world trade has expanded and multiplied continuously throughout this period, encouraged by reducing barriers and national borders promoted by 'peddlers' of this new era. The purpose of this study is to show that retailers are establishing purchasing offices in producing countries - or in nearby regions - to directly hire outsourced production

A indústria de defesa brasileira: o setor de carros de combate e a engesa

This paper analyzes the small and medium armored combat vehicle industry, in order to understand its modus operandi. We investigate the former largest Brazilian producer of small and medium armored combat vehicles, Engesa, and concluded that its world success was a result both of its privileged perception to occupy a market niche and of the special relationship among its CEO and the Brazilian Army. A combination of negative factors conduced the firm to its bankruptcy, in the beginning of the 1990s, but we also identified a huge business potential, which could be either occupied by Engesa, if it had not disappeared, or by a follower in this market.

Cultura empresarial e reestruturação produtiva na indústria brasileira: o caso da Lupo S/A

Founded in 1921, the company currently known as Lupo S/A is one of the most ancient textile and clothing industries in Brazil. In this article we aim to describe the general lines of the trajectory of this family company, currently producing socks, nightwear and sports articles. The focus of this paper is on the analysis of some strategies used by the company along its formation and development process, and, particularly, the way these strategies made possible the productive restructuring associated to the overcoming of the strong crisis which began in the end of the 80's and early 90's, contributing to its recent consolidation in the clothing industry. The leading hypothesis of the study is that pioneering connected to a strong organizational culture that has been formed and constructed since its foundation and that was reestablished in a more recent management were the factors which were responsible for the advances able to generate an innovation environment in products as well as in processes and management. The theoretical reflection selected to subsidize the cognitive construction of the study of the company is based on the historical approach of the development of the textile industry in Brazil and in studies about the importance of the action of the entrepreneur, in the role of the organizational culture and of innovation to choose strategies in companies. The research involved the analysis of documents and data of the company, as well as interviews with directors and employees. The results show a traditional company model, but also show the presence of a very advanced entrepreneurial dynamic. Modern world – known as a fordist industrial model – could already be noticed in the company when this production pattern was not clearly defined yet in the Brazilian industry. Nowadays, the company faces the challenge of globalization and the open competition in the international market which brings the rivalry of the greatest and best globalized companies.

O desenvolvimento da indústria farmacêutica no Brasil e na Índia: um estudo comparativo

The article shows how the development of the pharmaceutical industry in Brazil and India occurred, and why the industry in these two countries, which until the 1970s were much alike, today show significant differences. The historical analysis of the trajectories of the industries in both countries showed that the Indian industry has a higher technological content, due to, among others, the efficiency of public policies implemented since the 1970s, which were aimed at improving not only production, but also the technological development.

O efeito do fim do Acordo sobre Têxteis e Vestuários para a indústria brasileira: uma análise a partir da fronteira de produção estocástica

This article investigates the productivity and production function of thirteen large Brazilian textile and clothing companies before and after the end of the Agreement on Textiles and Clothing (AVT) that abolished import quotas in 2005. For this purpose, we estimate the stochastic production frontier in panel data between 1997 and 2008 and simultaneously an explanatory equation for the (in)efficiency of firms, as proposed by Battese and Coelli (1995). The results indicated that more efficient firms are the oldest. The total factor productivity of firms tended to fall, even after the end of quotas, increasing productivity only from 2007. Overall, firms from Santa Catarina were more efficient than those of other states.

O enunciatário da revista VEJA: contribuição para discussões sobre indústria cultural e cultura de massa

This work intends to “test” two theories about mass cultural products – one that understands them as syncretic and plural and another that sees them as homogenizators and aimed to a mixed audience. We chose Veja magazine as the object of this study and tried to understand how its internal sessions bring in their readers, with the goal of verifying whether readers shared characteristics. In the affirmative case, Veja would be directed to a specific reader; otherwise, it would be a syncretic cultural product. This answer should give us basis to reflect upon the opposition between both ways of thinking about mass culture and help us take a stand on this discussion. Obviously, we do not intend to give a definitive answer to the opposition between these two tendencies. The limits of this work are given by the investigated object itself: we intend to verify empirically how Veja, as a cultural product, solves the contradiction that the co-existence of these two opposite theories point about mass society.
