1. Chemical monitoring of baru (dipteryx alata vog.) pulp fermented beverage
Abstract Considering that the consumption of baru is not yet fully diffused among humans, it is possible to perceive the need for its greater use, mainly because it is a natural source of sugars, essential raw material for the production of various products, such as beverages fermented. In view of the above, the objective of this work was to develop fermente

3. Assessment of the Physicochemical Quality Indicators and Microbiological Effects of Brazilian Ozonized Vegetable Oils
The study of quality indicators in the process of obtaining ozonized vegetable oils is useful for monitoring the ozonation reaction. The Brazilian oils “dendê”, soy, corn, rice and sunflower were studied, all of them were ozonated applying different doses of ozone. Ozonized oils were evaluated by determining the physicochemical indexes of peroxide, acid

4. Tunnel vision in current chemicals management cannot deal with the unknown risk of synthetic chemicals in aquatic systems
Resumo A gestão e o manejo de poluentes químicos são focados na periculosidade, exposição e avaliação de risco. Esse processo é lento e não acompanha o surgimento de novas substâncias e o desenvolvimento do seu uso. O monitoramento ambiental foca em poucas substâncias que são bem conhecidas. Consequentemente, a maioria das substâncias emitidas

6. AVALIAÇÃO DOS TEORES DE Pb, Cd, Sn, Co, Hg, Mo E As EM SOLOS DA PENÍNSULA FILDES - ANTÁRTICA
Antarctic Continent is one of the few places that has not been explored at all, but studies show that this place is suffering interference by human activities. Therefore, monitoring of this region becomes very important. After optimization and verification of the methodology, the concentrations of Pb, Cd, Sn, Co, Hg, Mo and As in soil samples collected in th

7. Characterization of Siloxane-poly(methyl methacrylate) Hybrid Films Obtained on a Tinplate Substrate Modified by the Addition of Organic and Inorganic Acids
Tinplate is used to food packaging and other types of packages. The corrosion resistance of the tinplate has been study due the necessity of an alternative to high environmental impact of chromatization process. Therefore protective coatings as hybrid films base elaborations with different acids are studied to improve the barrier effect against corrosion. Th

8. Recuperação de solo salino-sódico por fitorremediação com Atriplex nummularia ou aplicação de gesso. / Reclamation of saline-sodic soil by phytoremediation with Atriplex nummularia or application gypsum.
Arid and semi-arid environments may present salty soils, which hamper plant growth, being removed from productive process constituting degradation cores. Under these conditions, glycophyte plants cant growth because high levels of salts hinder their metabolism, however, for halophytes this is favorable environment and these plants may represent a key to soil

9. InfluÃncia local para modelos geoestatÃsticos utilizando a produtividade da soja e atributos quÃmicos do solo / Local influence on geostatistical models using soy productivity and chemical soil
Soy is one of the main crops in Brazil and in the region of Cascavel / PR, where agricultural production is large, although some factors that affect productivity, monitoring and process management have been diagnosed by geostatistical models for analysis of agricultural data. Studies on the spatial variability of soil attributes associated with soybean yield

10. Tratamento de Ãgua residuÃria de fecularia em reator anaerÃbio com leito fixo de pedras de calcÃrio dolomÃtico / Starch wastewater treatment in anaerobic reactor containing Dolomitic limestone
The cassava processing for starch or flour production generates some wastewater (manipueira) with high organic load and toxic compounds, which cause environmental degradation. In the western Paranà region, there are several starch factories, so its waste generation is a concern for the correct treatment and disposal. Thus, anaerobic reactors are a cost-effe

11. Parâmetros de monitoramento na produção industrial de componentes em zircônia parcialmente estabilizada com óxido de magnésio / Monitoring parameters for the industrial production of pieces made of magnesia-partially-stabilized zirconia
Zirconia has been widely applied on production of structural components, mainly due to its great mechanical properties. However, these properties are associated to the zirconia tetragonal and cubic phases, which are stable only on high temperatures on pure material, being necessary doping the material with some oxides to keep these phases at ambient temperat

12. Avaliação técnica e microestrutural entre tijolos dolomíticos de alto desempenho para a indústria siderúrgica
The refractory dolomite is widely used as coating for ladles work in steelmaking process for its excellent refractoriness in terms of service. The use of this refractory is due to a natural formation of a protective layer, which enhances the life of the refractory, resulting in increased equipment life. This work is based on a comparative study between two b
