A industrialização e a presença das multinacionais no Brasil: um esboço preliminar

O objetivo deste trabalho é o de, inicialmente, caracterizar o processo industrial brasileiro, procurando detectar as forças propulsoras e as forças restritivas que agiram sobre o processo e suas distorções, ocorridas pela dependência econômica a outros países mais desenvolvidos e, também, pelo próprio modelo adotado. Um rápido retrospecto histórico da economia brasileira, desde e principalmente, o ciclo do café, faz-se necessário para compreender-se o sistema oligárquico-fundiário que dominou por quase quatro séculos a gradativa transição de uma economia primário-exportadora para uma economia que buscava substituir suas importações.

Industrialização e emprego formal: uma análise para os municípios da região metropolitana do Cariri nos anos de 1990 e 2000

The Northeast has a record of fighting to reduce disparities. In late 1950, the state intervened through SUDENE, organizing and planning the promotion of development through industrialization. This study aims to identify the characteristics of the industrialization of the Northeast and evolution of formal employment in the metropolitan area of Cariri, located in the southern state of Ceará, in the case of the municipalities of Crato, Juazeiro do Norte and Barbalha (CRAJUBAR) in decades of 1990 and 2000. The assumption permeates the SUDENE with public policies to encourage the industry, causing profound changes in the cities studied. The results indicate that the Cariri since the 1960 has been benefiting the programs implemented by SUDENE. With the implementation of these programs, with in a set of circumstances based on local vocations and state policies, there was a spatial distribution industry, triggering a growth and development on the provision of formal jobs in the industrial sector

Influência do florescimento e grau de isoporização na qualidade de variedades de cana-de-açúcar aptas á industrialização no meio de safra

Among the sugar cane potential uses include those related to the extraction of products and byproducts from the stalk. The sugarcane flowering causes morphological and physiological changes in plant and in the presence of pith, promotes changes in the stalk, reducing the raw matter quality. Most of the areas planted with sugarcane in the South-Central region of Brazil are subject to flowering, however, this feature varies depending on the variety used. There are different pith diameters related to the flowered or induced stalks, and damage to the raw matter quality are still controversial. The objective of this experiment was to evaluate the response of cane sugar varieties in relation to the flowering, pith and chemical and technological parameters, and their relationship with the pith degree. The experimental design was a completely randomized with sis treatments (varieties: IAC91-1099-4004IAC94, IAC95-5000, SP81-3250, CTC and RB855536 15) and three replications. Were evaluated the flowering, based on morphological changes in the apical bud, the pith intensity by the percentage determination of internodes occupied by whitish and spongy tissues and and pith diameter, by measuring the diameters of the changes in the internodes, expressed in percentage, in addition to chemical (juice total acidity) and technological (fiber, reducing sugars and sugar cane Pol) parameters. The flowering occurrences were accompanied by higher pith intensity. The flowering induction contributed to the lower raw matter quality, although the pith volume was lower. The pith and flowering did not affected the sugarcane sucrose content. Increases in levels of fiber, sugars and acidity were observed only in cases where the diameter of the area spongeous exceeded 50% of stalk diameter. The variety that had the best and worse response was RB855536 and CTC 15, respectively.

Aproveitamento de subprodutos da industrialização do escargot

The waste in the industries of escargot processing is very big. This is composed basically of escargot meat out of the commercialization patterns and the visceras. In this context, there is a need to take advantage to the use of these sub-products. A possibility should be drying them and transforming them in a certain form to be reused. Than, the present work has the objective of studying the reutilization of the sub-products of the escargot industrialization for by means of drying process. The samples were transformed in pastes, through a domestic processor for approximately 1 minute and compacted in trays of aluminum without perforations with three different heights (5 mm, 10 mm and 15 mm). The drying was accomplished in a tray dryer with air circulation and transverse flow at a speed of 0,2 m/s and three temperature levels (70°C, 80°C and 90ºC). A drying kinetics study was accomplished for the obtained curves and for the heat and mass transfer coefficients using experimental procedures based in an experimental planning of 22 factorial type. Microbiological and physiochemical analysis were also accomplished for the in nature and the dehydrated sub-products. In the drying process, it was observed the great importance of the external resistances to the mass transfer and heat in the period of constant tax influenced by the temperature. The evaporation taxes indicated a mixed control of the mass transfer for the case of the thickest layers. As already expected, the drying constant behavior was influenced by the temperature and thickness of the medium, increasing and decreasing. The statistical analysis of the results, in agreement with the factorial planning 22, showed that the fissures, the shrinking of the transfer area and the formation of a crust on the surface might have contributed to the differences between the practical results and the linear model proposed. The temperature and the thickness influenced significantly in the answers of the studied variables: evaporation tax and drying constant. They were obtained significant statistical models and predictive ones for evaporation tax for the meat as well as for the visceras

Estudo de técnicas para o tratamento alternativo de efluentes oleosos oriundos da industrialização da castanha de caju

An evaluation project was conducted on the technique of treatment for effluent oil which is the deriving process to improve cashews. During the evaluation the following techniques were developed: advanced processes of humid oxidation, oxidative processes, processes of biological treatment and processes of adsorption. The assays had been carried through in kinetic models, with an evaluation of the quality of the process by means of determining the chemical demand of oxygen (defined as a technique of control by means of comparative study between the available techniques). The results demonstrated that the natural biodegradation of the effluent ones is limited, as result using the present natural flora in the effluent one revealed impracticable for an application in the industrial systems, independent of the evaluation environment (with or without the oxygen presence). The job of specific microorganisms for the oily composite degradation developed the viability technique of this route, the acceptable levels of inclusion in effluent system of treatment of the improvement of the cashew being highly good with reasonable levels of removal of CDO. However, the use combined with other techniques of daily pay-treatment for these effluent ones revealed to still be more efficient for the context of the treatment of effluent and discarding in receiving bodies in acceptable standards for resolution CONAMA 357/2005. While the significant generation of solid residues the process of adsorption with agroindustrial residues (in special the chitosan) is a technical viable alternative, however, when applied only for the treatment of the effluent ones for discarding in bodies of water, the economic viability is harmed and minimized ambient profits. Though, it was proven that if used for ends of I reuse, the viability is equalized and justifies the investments. There was a study of the photochemistry process which have are applicable to the treatment of the effluent ones, having resulted more satisfactory than those gotten for the UV-Peroxide techniques. There was different result on the one waited for the use of catalyses used in the process of Photo. The catalyses contained the mixing oxide base of Cerium and Manganese, incorporated of Potassium promoters this had presented the best results in the decomposition of the involved pollutants. Having itself an agreed form the gotten photochemistry daily paytreatment resulted, then after disinfection with chlorine the characteristics next the portability to the water were guarantee. The job of the humid oxidation presented significant results in the removal of pollutants; however, its high cost alone is made possible for job in projects of reuses, areas of low scarcity and of raised costs with the capitation/acquisition of the water, in special, for use for industrial and potable use. The route with better economic conditions and techniques for the job in the treatment of the effluent ones of the improvement of the cashew possesses the sequence to follow: conventional process of separation water-oil, photochemistry process and finally, the complementary biological treatment

Uso da cor da casca como indicador de qualidade do maracujá amarelo (Passiflora edulis Sims. f. flavicarpa Deg.) destinado à industrialização

As características físico-químicas do maracujá amarelo em três estádios de cor de casca (1/3 amarelo, 2/3 amarelo e inteiro amarelo), em quatro épocas da safra/99 foram avaliadas, visando estabelecer o ponto de colheita de melhor qualidade da fruta para a industrialização. Foram determinados o tamanho dos frutos, a cor da casca e da polpa, o rendimento de extração da polpa, o teor de sólidos solúveis totais, o pH, a acidez total, o ratio e o teor de vitamina C. Foi empregado o delineamento experimental inteiramente casualizado, com 8 repetições, 5 frutos por parcela e 3 tratamentos. Os resultados mostraram que o rendimento de polpa não apresentou diferença significativa entre os tratamentos e entre as colheitas. Com relação à cor da polpa, houve diferença significativa entre os três estádios apenas na 1ª colheita. Os frutos de casca 1/3 amarela apresentaram teor de sólidos solúveis significativamente inferior aos demais apenas na 3ª e 4ª colheitas, mas o maior valor médio ocorreu na 4ª colheita. O teor de acidez total dos frutos de casca inteira amarela foi significativamente inferior àqueles das colheitas 2, 3 e 4. Os valores mais elevados de vitamina C foram obtidos na 1ª colheita e, os frutos de casca 1/3 amarela apresentaram teores significativamente inferiores nas colheitas 1 e 2. de maneira geral, os resultados indicaram que, embora tenham ocorrido algumas diferenças nas características físico-químicas dos frutos nos diferentes estádios de cor de casca, frutos colhidos em todos os estádios de cor de casca estudados apresentaram-se adequados à industrialização.

Efeitos de parâmetros de fermentação na produção de etanol a partir de resíduo líquido da industrialização da mandioca (manipueira)

Effect of fermentation parameters on ethanol production from cassava liquid residue (manipueira). "Manipueira", a liquid residue from the processing of cassava starch and flour, has recognized high pollution potential. Aiming at a possible use of "manipueira" as raw material for ethanol production, this study aimed to evaluate the effect of the percentage of inoculated yeast and fermentation temperature on the chromatographic profile of the components of wine of "manipueira". The residue was characterized for starch and sugar content, as well as pH and total acidity. The residue was hydrolyzed by the action of enzymes Termamyl 120 L and AMG 300 L. The hydrolysate obtained was fermented under different experimental conditions. A factorial central composite design (2(2)) with two independent variables and the response surface methodology were used to evaluate the results. The results showed a significant effect of variable parameters on the components of wine. The conditions of low fermentation temperature and lower percentages of inoculated yeast were the most appropriate to obtain ethanol from "manipueira".

A industrialização das editoras e dos livros didáticos nos Estados Unidos (do século XIX ao começo do século XX)

Cet article examine la création de l'industrie du livre didactique aux États-Unis à partir des années 30 du XIXe siècle. Dès les années 20 de ce siècle, des maisons d'éditions sises dans les villes de New York et Boston étaient déjà capables de publier différents types de livres didactiques et de petits livres pour enfants et de les vendre aux quatre coins du pays, où elles avaient détaché des fonctionnaires pour ce faire. À la fin de cette décennie, le processus de production s'est sophistiqué avec l'organisation et l'entraînement d'équipes spécialisées dans l'écriture de schoolbooks. Dans le sillage de ces premières maisons d'éditions, d'autres se sont affirmées et sont devenues des puissances nationales et internationales jouant un rôle décisif aussi bien dans l'américanisation des énormes vagues d'immigrants qui sont arrivées dans ce pays, dès la moitié du XIXe siècle, que dans celle des peuples soumis à la domination militaire ou économique des EUA.
