Jarina: o marfim das biojóias da Amazônia

A palmeira jarina (Phytelephas macrocarpa) é endêmica da Amazônia, onde se desenvolve sobre antigas planícies de inundação, cujos sedimentos são constituídos por quartzo, minerais de argila 2:1 e feldspatos, constituindo solos férteis e pouco ácidos a neutros. As sementes dessa palmeira são incluídas entre as gemas orgânicas raras. Devido a sua cor e brilho, as sementes são comparadas ao marfim animal, apesar da baixa dureza e baixa densidade, sendo empregadas na manufatura de biojóias e artefatos. Esses produtos são bem aceitos comercialmente devido às sementes serem susceptíveis a mudança de coloração e outros melhoramentos. Infelizmente, as jóias não apresentam vida longa, pois as sementes podem sofrer ataque de microorganismos entre 5 e 10 anos. Se houver uma política adequada para cadeia produtiva das sementes de jarina, a mesma poderá se tornar de grande importância para o desenvolvimento da região Amazônica, ao criar novas oportunidades de trabalho e agregação de valor aos produtos. No entanto faz-se necessário um especial cuidado para evitar exploração inadequada das sementes para assegurar a preservação da espécie.

Estudo sobre fornos de tratamento térmico e propostas de cogeração de energia em usina siderurgica não integrada

Steel industry is a sector heavily dependent on energy, both electrical and thermal. Since the receipt of raw materials to the shipment of finished products to customers, through mergers, casting, rolling, heat treatment, inspection, among others, high amounts of energy are demanded, generating very significant costs to the productive chain in its entirety . Therefore, any alternative that favors the reduction in energy consumption or barateie the cost of this is very welcome. Within this context, this paper aims to make a technical and economic analysis of installing a cogeneration plant in the field rolling in a non-integrated steel mill. Two configurations are proposed plants, with one being the use of heat from waste gases from furnaces existing in the area mentioned and another with the use of heat from waste gases from an internal combustion engine. Both proposals are evaluated technically and later is done the economic analysis, calculating the financial return (pay back) in relation to the investment required, operation and maintenance of the plant

Avaliação da biodegradação de tolueno por fungos isolados de ambientes associados ao petróleo

Spills can ocurr during oil productive chain and contaminate various environments due to the toxicity of monoaromatics hidrocarbons. Toluene stands out for being agressive to the nervous sistem and teratogenic, with high mobility and solubility in water, which facilitates environmental impact. Studies show that fungi are potential aromatic compounds assimilators, encouraging new researches about its use on the recovery of contaminated sites. This study aimed to select and characterize fungus with potential for biorremediation of toluene. 50 fungi were selected of the Collection of Microorganisms of Interest for Oil Gas and Biofuels, of UNESP Rio Claro, all of which were isolated from sites contaminated with monoaromatic hydrocarbons. Two trials were realized to select the microorganism with greater potential. The first test evaluated fungal growth under toluene saturated atmosphere. 24 fungi were chosen because its greater biomass production to participate in the next trial, the degradation in plates test, where the blue redox agente, DCPIP, indicates the degradation reaction, turning colorless. From this teste was possible to select one isolate which showed higher growth and stronger medium discoloration as the microorganism with the greatest potential to assimilate toluene. The Trichoderma cf. koningii had its potential evaluated through gas cromatography. The experiment proved the efficiency of the methodology, with positives results from the method validation and the effectiveness demonstrated of the LA-PHA-PACK bottles to prevent the volatilization of toluene during the 21 days of experiment. Being reliable its use for monitoring toluene decay associating it with degradation. This results are important because there aren't many methodologies and vials efficient to the purpose of this work. In the present study the degradation rates demonstrated no significant decay of the concentration of hydrocarbon. That may be related to the...

Relacionamento e coordenação da cadeia produtiva da mandioca no Noroeste do Paraná

The production of starch and cassava starch (Manihot esculenta) if has shown to an important business for the region the northwest of the Paraná, generating income and job for a significant agricultural producers. The production of the region is processed for industries at private capital and cooperatives of producers. The study involving agricultural producers and one of the most important cooperatives of the region (C-Vale) objectified to evaluate the relationships between cooperative and producers, and the mechanisms of coordination of the productive chain. The results had disclosed that the relationships are not harmonious, generating opportunism situations, high costs of transaction and diffidence in the operations between producers and cooperative. Also if it perceived a difficulty of coordination of the productive chain, due to lack of integration between the partners, what it affects the competitiveness and the efficiency of the sector.

Innovation in industrial clusters: a survey of footwear companies in Brazil

The aim of this study is to characterize the relationships in innovation and business clustering processes in the productive chain of small and medium enterprises (SME) of Brazil. The object of study are SMEs the local procuctive cluster of the shoes in Franca, State of São Paulo. The conceptual model developed is based on the following constructs: vertical integration, innovation and characteristics of the cluster, and it is focused on identifying the agents that act predominantly in product innovation processes in the cluster. A survey was conducted. It was found that there is cooperation between the companies in the productive arrangement studied, and that shoe manufacturers are those who, predominantly, stimulate innovation within the cluster.

Ocorrências e usos do Tucumã (astrocaryum vulgare mart) em comunidades ribeirinhas, quilombolas e de agricultores tradicionais no município de Irituia, Pará

The aim of the study is to demonstrate the occurrence and usage of the Tucumã (Astrocaryum vulgare Mart.) in rural areas of the Municipality of Irituia, in the State of Pará (Brazil), since the use of the palm part of the traditional culture of communities of farmers, riparian and quilombola, used in curing diseases in human and domestic animals, building shelters, obtaining fibers, production of tools and crafts, hunting and fishing. In addition to the uses reported by the population, tucumã has potential for the production of oil and biodiesel. In this sense, the Federal University of Pará – UFPA, in a partnership with the Irituia’s Municipal Government, is studying the implementation of an oleaginous processing plant in the municipality, among them, and includes the Tucumã as a potential source. Such proposal stipulates the production in the agroforestry system, as an alternative to the slash and burn agriculture in the region, reconciling environmental conservation with territorial rural development. Considering the results obtained in the field, it has been found an average of 9.4 stumps per hectare, each stump having 7.7 stipes and 4.7 racemes with up to 146 fruits. If all the Tucumã’s stumps were kept until they reached their average productivity capacity, it is estimated that the fruit production in the rural area of the municipality would be around 132.060 tons, which could produce up to 12.665,4 tons/year of pulp oil and 4.768,4 tons/year of nut oil, confirming the supply of raw material to move this productive chain.

Estratégias de sinalização da qualidade da carne suína ao consumidor final

A suinocultura destaca-se na economia brasileira. Contudo, avaliando-se o consumo interno da carne suína in natura, observa-se uma estagnação em patamares baixos. O artigo tem como objetivo analisar as principais iniciativas adotadas pelo Sistema Agroindustrial (SAG) da carne suína no Brasil visando sinalizar qualidade aos consumidores. Devido à marcante assimetria de informações, ressalta-se a importância da organização da cadeia produtiva, melhor direcionando esforços para a expansão do mercado interno. Este trabalho sugere ações visando aprimorar a coordenação deste SAG com vistas à melhoria na qualidade da carne ao consumidor e à redução da informalidade.
