13. Utilização de resíduos industriais como substratos de baixo custo para a produção de biossurfactante por Candida sphaerica
Surfactants are amphipathic agents with application in different industries, such as the petroleum, food and pharmaceutic. Many kinds of chemical surfactants are being used nowadays, although the development of alternative products, with biodegradable nature and lower toxicity, as the so called biosurfactants, metabolites from microorganisms, is a sound stra

14. Produção de astaxantina por Mucor javanicus (UCP 69), a partir de meio definido e utilizando resíduo industrial (milhocina e quirera de milho) / Produção de astaxantina por Mucor javanicus (UCP 69), a partir de meio definido e utilizando resíduo industrial (milhocina e quirera de milho)
Com a recente substituição dos pigmentos sintéticos pelos carotenóides naturais, pesquisas têm sido desenvolvidas para viabilizar uma maior produção destas substâncias, através de fontes biológicas alternativas. Neste trabalho foi estudada a produção de astaxantina por uma amostra de Mucor javanicus utilizando o meio definido Hesseltine e Anderso

15. Utilização de resíduos da indústria madeireira para fabricação de chapas cimento-madeira / Utilization of the lumber industry for cement-wood particleboard production
A industrialização da madeira gera grande quantidade de resíduos, que são lançados no meio ambiente, e não são aproveitados em sua totalidade, ou quando no máximo são utilizados para geração de energia causando também poluição ambiental. Esta pesquisa teve como objetivo avaliar por meio de ensaios físicos, mecânicos e análise da interface fi

16. Chemical analysis of solid waste for agricultural and environmental studies / Analise quimica de residuos solidos para estudos agroambientais
The practice of using organic and inorganic wastes as fertilizers is an increasingly important agricultural practice. The risks of indiscriminate disposal of waste onto the soil are associated mainly with the transport of pollutants by the infiltration of percolated liquids, which are responsible for the contamination of the subsoil and underground waters. B

18. Síntese e caracterização de substâncias semelhantes aos ácidos húmicos de carvão de eucalipto, e sua interação com diclorofenol, cálcio, manganês e alumínio / Synthesis and characterization of humic acid-like substances from eucalypt charcoal, and its interaction with diclorofenol, calcium, manganese and aluminium
A wide range of commercial products containing humic substances have been applied successfully in agricultural and environmental remediation systems. Regarding their beneficial remediation characteristics, there is a high potential to adsorb heavy metals and organic pollutants, thus reducing their bioavailability. Industrially, they are extracted from non-re

19. Analysis implementation of lean manufacturing system in an automotive parts manufacturing enterprise. / ANÃLISE DA IMPLANTAÃÃO DE UM SISTEMA DE MANUFATURA ENXUTA EM UMA EMPRESA DE AUTOPEÃAS
In general, industries, mainly the big or medium ones, had already come across situations typically a result from being an overly productive company, meaning that they produce more than clients can absorb or in a rhythm above the required. They also are exposed to related situations such as deviation or distortion of production information, disorder of the f

20. Chronic elemental mercury intoxication: clinical and field studies in lampsocket manufacturers.
Four workers chronically exposed to elemental mental mercury in a lampsocket manufacturing factory were studied. The clinical manifestations were severe in one, mild in another, and suspicious in the remaining two. Correlation between severity of clinical features and increased urinary mercury concentrations was found. The time weighted average mercury conce

21. Twinning in human populations and in cattle exposed to air pollution from incinerators.
Human populations and animals are often exposed to the airborne pollutants in plumes from incinerators. The incineration of chemical and other waste may release polychlorinated hydrocarbons, some of which have oestrogenic properties. Increased numbers of twins had been reported anecdotally in cattle at risk from plumes from two incinerators near the town of
