Transference of lutein during cheese making, color stability, and sensory acceptance of prato cheese

The consumption of lutein is associated with the prevention and reduction of age-related macular degeneration. Its incorporation into Prato cheese as a yellowish food coloring is a valid alternative to increase the daily intake of this compound. However, part of the lutein added may be lost in the whey during the cheese making, or it can be degraded by light during storage, resulting in color changes reducing the sensory acceptance of the cheese. The objectives of this study were to determine the transference of the lutein (dye), added to the milk, in the whey, and cheese, to evaluate the effect of the lutein addition, light exposure, and storage time on the cheese color, and to verify the sensory acceptance of Prato cheese with addition of lutein. The lutein recovery of cheese was 95.25%. Color saturation (chrome) increased during storage time resulting in a cheese with more intense color, but there were no changes in the hue of the cheese. Adjusting the amount of lutein added to Prato cheese may lead to greater acceptance. The high recovery of lutein in the cheese and the fact that the hue remained unchanged during storage under light showed that the incorporation of lutein into Prato cheese is feasible from a technical point of view.

Poder de barganha dos sindicatos e negociações coletivas na indústria do Rio Grande do Sul, 1979-1995

This paper analyses the relationship between bargaining outcomes in seventeen units regarding the manufacturing sector in Rio Grande do Sul, and change in the relevant economic environment from 1979 to 1995. Theories on the determinants of bargaining outcomes are discussed in order to provide a basis for hypothesizing about the specific case. Statistical outcomes suggest that collective bargaining have been basically influenced by unemployment, manufacturing relative prices, the stabilization policies starting in 1986, and, specifically for negotiated minimum wages, change in the official rates of minimum wages.

Salários, produtividade e lucros na indústria brasileira, 1945-1978

Wages, productivity and profits in the Brazilian manufacturing industry, 1945-1978. This article investigates the distribution between profits and wages in Brazil's manufacturing industry from 1945 to 1978. First, the article provides yearly series of average real wages and labour productivity, from which labour unit costs and the distribution between profits and wages in the manufacturing industry are estimated. Second, the article addresses the behaviour of wages, labour productivity and industrial income distribution in the context of variable economic, political and institutional conditions which prevailed in post-war Brazil. The results of the quantitative analysis allow us to assess both the trends and the yearly behaviour of the manufacturing income distribution during a key period of the Brazilian economic history.

Diversificação ou especialização: uma análise do processo de mudança estrutural da indústria brasileira

Diversification or specialization: an analysis of the process of structural change of the Brazilian industry. Based on findings by Imbs and Wacziarg (2003), whose empirical study has established the existence of a U-shaped pattern in the evolution of industrial specialization relative to per capita income, this paper aimed at determining the path of structural change followed by the Brazilian industry in the last decades and at comparing it with the evidence for other countries. The conclusion is that the stage of diversification of the Brazilian industrial structure has ended at a relatively low level of per capita income.

Regime cambial e mudança estrutural na indústria de transformação brasileira: evidências para o período (1994-2008)

Exchange rate regime and structural changes in the Brazilian manufacturing industry. This article proposes an analysis of the relationship between exchange rate regime and evolution of the Brazilian manufacturing industry during the period 1980-2008. Its main purpose is to detect the direction of the structural changes imposed by the new form of international insertion consolidated throughout the 1990s. The work also provides new empirical evidence regarding the assumptions of deindustrialization and "Dutch disease", which mark the current debate on the effects of the appreciation of real exchange rate in the Brazilian economy.

Indústria e crescimento econômico: evidências para países desenvolvidos e em desenvolvimento

The work develops an empirical investigation on the relevance of industry / GDP, manufacture / GDP and industrial employment / total employment on long run growth using panel data. The results indicate the existence of a direct and significant relation for industry (manufacture) share to GDP and industrial employment for long run growth. The annual impact on growth of a 10% increase, over a five year period, in the industry share to GDP (manufacture share to GDP) ranges from 0.19% to 0.32% (0.2% to 0.4%) and for the industrial employment / total employment it varies from 0.3% to 0.5%.

Desempenho e fragmentação da indústria de alta tecnologia do Mercosul

RESUMOO objetivo deste artigo é avaliar a real inserção do Mercosul no comércio internacional de manufaturas de alta tecnologia e o grau de evolução ao longo da cadeia tecnológica. A principal contribuição deste artigo é a construção de um indicador de valor adicionado, resultado da diferença entre as exportações de bens finais e as importações de partes e componentes. Tal indicador permite uma análise mais adequada, em termos de saldo comercial, de setores cada vez mais inseridos em processos de fragmentação produtiva. A principal conclusão é de que não há evidências fortes de que tais países estejam avançando para etapas mais a jusante das cadeias de valor nos setores de alta tecnologia, com exceção do setor de aeronaves (especialmente do Brasil).

A atualidade da discussão sobre a indústria cultural em Theodor W. Adorno

Este ensaio vem problematizar acerca da atualidade do conceito de indústria cultural (Kulturindustrie), no projeto da teoria crítica de Theodor W. Adorno, objetivando mostrar que as atuais limitações impostas ao debate derivam mais do fundamento não-dialético dos que apontam sua restrição do que da própria potência da teorização frankfurtiana.

Memòria d’una indústria desapareguda: la bòbila d’en Soler

En aquest estudi pretenc revalorar el patrimoni cultural, natural i industrial de Vilafant. Tot i que les directrius del meu treball, es centren de manera especial en el patrimoni industrial, ja que en aquests moments l’Ajuntament de Vilafant, té especial interès en potenciar l’estudi de l’activitat rajolera, que va assolir el seu màxim esplendor amb la construcció de la bòbila d’en Soler l’any 1880

Avaluació de la tècnica de fitoextracció per a la reducció de concentracions de metalls pesants en sòls contaminats per la indústria minera

L’explotació minera, especialment la mineria metàl•lica, ha estat sempre associada a riscos de contaminació ambiental de sòls, aigües i vegetació, originats per l’activitat extractiva, les operacions de concentració dels minerals i pels emplaçaments de residus miners sense una gestió adequada. En molts casos els residus miners s’abocaven directament a rius i rierols o s’acumulaven en piles pròximes a centres habitats i activitats agrícoles. Concretament s’estudia els cas de les mines d’Osor. Donada la possible presència de quantitats elevades de metalls pesants en aquests sòls es decideix avaluar una tècnica de remediació de sòls lleugera com la fitoextracció. La fitoextracció es basa en l’ús de plantes bioacumuladores que absorbeixen metalls del sòl. Aquesta tècnica permet una descontaminació del sòl no agressiva i de baix cost però requereix un tractament de llarga durada
