1. Determination of Alkyl Esters Content by Gas Chromatography: Validation of Method Based on Short Column and Response Factor
In this study an analytical method, based on gas chromatography with flame ionization detection, using a short column and response factor (GCSCRF), was validated for the quantification of fatty acid alkyl esters (methylic or ethylic). During the validation process, the proposed method was employed to analyze twenty samples of fatty acid methyl esters and fat

4. Desenvolvimento de biossensores eletroquimicos como ferramenta para avaliação da capacidade antioxidante de extratos vegetais / Development of electrochemical biosensors as a tool for evaluation of the antioxidant capacity of vegetables extracts
This work describes the development of two kind of electrochemical biosensors to evaluate the antioxidant capacity of vegetables extracts. The first biosensor developed was based on horseradish peroxidase immobilized on silica coated with titanium oxide and this material was employed to modify the carbon paste. In the optimized conditions, the biosensor resp

5. Método colorimétrico para determinação de dióxido de nitrogênio atmosférico com preconcentração em coluna de c-18
An alternative analytical method for nitrogen dioxide (NO2) in atmosphere was developed. The collection of NO2 is performed by a Sep-Pack C-18 cartridge impregnated with 11% (v/v) of triethanolamine plus 3,6 % (v/v) of ethylene glycol plus 25 % (v/v) of acetone combined solution. When the impregnating is used, NO2 is collected with good repeatibility (CV = 3

6. Eficacia de um teste microbiologico para estreptococos do grupo mutans na avaliação do risco de carie
The aim of this study was to evaluate the efficacy of a microbiological test for estimation of mutans streptococci levels in caries risk assessment. Eighty-one volunteers from 6th up to 8th grades from Piracicaba s public schools were assessed for dental caries. A researcher with great skills in examining and treating patients with high caries activity perfo
