1. Development of low-cost equipment to instrumentalize the ASTM D 1209-00 method / Desenvolvimento de equipamento de baixo custo instrumentalizar o metodo ASTM D 1209-00
The ASTM D1209-00 method describes the procedure for the visual measurement of the color of essentially light colored liquids, which involves the visual comparation between the color of the samples with the color of Pt-Co standards solutions, with concentration from 1 to 500 unities of Pt-Co, the ASTM D 1209-00 scale (solutions obtained by mixing potassium c

2. Efeito de reguladores de crescimento vegetal nas respostas de cultivares de feijoeiro ao Southern bean mosaic virus (Sobemovirus)
A aplicação de determinados reguladores de crescimento em plantas pode resultar na indução de resistência contra ataques subseqüentes de patógenos. Este fenômeno é conhecido como resistência sistêmica adquirida (SAR) e vários mecanismos estão envolvidos, entre eles a resposta de hipersensibilidade (HR), o aumento na atividade das enzimas peroxid

3. Estudo comparativo de métodos analíticos para a determinação de Fe e Ti em cimento Portland.
In the present work analytical methodologies were studied for the determination of iron and titanium in Portland cement. The cement samples were dissolved with hot HCl and HF, being compared then through four analytic methods: molecular absorption spectrophotometry using the reagents 1,2-hidroxibenzene-3,5-dissulfonic acid (Tiron) and the 5-chloro-salicilic

4. Investigações envolvendo titulação termometrico catalitica
The influence of the composition of titrand and titrant on the shape of titration graph involved in the alkalimetric titration of acids in water-dimethylsulfoxide-acrylonitrile medium by catalytic thermometric titrimetry has been investigated. In this study it was possible to suggest the reaction responsible for the rise in temperature for different composit
