4. Buriti of the cerrado of Minas Gerais, Brazil: physical and chemical characterization and content of carotenoids and vitamins
Abstract The fruit species of the Brazilian Cerrado, such as buriti (Mauritia vinifera ), occupy a prominent position in the ecosystem since they contribute to the economic potential of the region and have high nutritional value. We aimed to evaluate the physical characteristics, chemical composition and content of vitamin C, carotenoids, vitamin E and fola

5. Simultaneous biodegradation of phenol and cyanide present in coke-oven effluent using immobilized Pseudomonas putida and Pseudomonas stutzeri
ABSTRACT Discharge of coke-oven wastewater to the environment may cause severe contamination to it and also threaten the flora and fauna, including human beings. Hence before dumping it is necessary to treat this dangerous effluent in order to minimize the damage to the environment. Conventional technologies have inherent drawbacks however, biological treatm

6. Effect of vacuum and oven drying on the radical scavenging activity and nutritional contents of submerged fermented Maitake (Grifola frondosa) mycelia
Abstract Maitake (Grifola frondosa) mycelia contain high dietary and medicinal values that have gained great attentions from consumers. Proper drying can preserve their bio-availabilities prior to subsequent processing or consumption. Pure Maitake (Grifola frondosa) strain was cultivated in Mushroom Complete Medium (MCM) using submerged fermentation for 14 d

7. Drying Contraction Assessment of Ceramic Products Produced by Extrusion or Pressing Formulated with Sheep Wool Waste
The main aim of this paper was to evaluate ceramic products containing a percentage of ash from sheep wool waste through drying linear shrinkage from a small brickyard in Bagé - RS. The ash percentages used in the formulation were 0, 5, 10, 20 and 30%. Raw materials were analyzed by Energy Dispersive X - ray Fluorescence (XRF/EDX). The methods used to shape

8. Qualidade da madeira de Eucalyptus para a produção de carvão vegetal / Wood quality of Eucalyptus for charcoal production
The present study aimed to determine the properties of wood and charcoal from different clones of Eucalyptus spp. Six clones at 7.5 years old were evaluated and the samples were from a clonal test of a forestry company, located in the city of Lassance, Minas Gerais, Brazil. For wood, basic density, heart/sapwood ratio, morphological analysis of fibers and po

9. Prediction total specific pore volume of geopolymers produced from waste ashes by fuzzy logic
In the present work, total specific pore volume of inorganic polymers (geopolymers) made from seeded fly ash and rice husk bark ash has been predicted by fuzzy logic. Different specimens, made from a mixture of fly ash and rice husk bark ash in fine and coarse form together with alkali activator made of water glass and NaOH solution, were subjected to porosi

10. Study of the chemical behavior during the ring formation of clinker in cement plant. / Estudo do comportamento quÃmico durante a formaÃÃo de anÃis de clÃnquer em fÃbrica de cimento.
The formation of thick collages in firing zone furnace of clinker in cement plants, called clinker ring, is a phenomenon that creates economical and environmental disorders. To remove the clinker ring it is necessary to cool up the oven for 24 hours cutting it with a breaking machine. This process is dangerous and highly cost-consuming, since the furnace fai

12. Caracterização de amostras comerciais de vermicomposto de esterco bovino e avaliação da influência do pH e do tempo na adsorção de Co(II), Zn(II) and Cu(II)
Some commercial samples of vermicompost from bovine manure (humus) were characterized by thermogravimetry with respect to humidity, organic matter and ash contents, the percentages of which range from 6.55 to 5.35%, 53.01 to 69.96% and 46.44 to 66,14%, respectively. The capacity of adsorption of Cu2+, Zn2+ and Co2+ ions by these samples has been evaluated as
