3. Simultaneous Determination of Different Phenolic Compounds Using Electrochemical Biosensor and Multivariate Calibration
Phenolic compounds are important environmental contaminants due to their high toxicity and persistence in the environment. The use of enzyme-based electrochemical biosensors is a simple, sensitive and low-cost alternative for the determination of these pollutants in contaminated waters. However, in most cases, it is impossible to detect specific compounds in

4. Análise dos procedimentos e critérios de implantação de feixes de raios X de referência ISO 4037 em baixas energias
According to the radiological protection principles, practices involving ionizing radiation must be planned and carried out under the guarantee that the values of individual doses, the number of people exposed to radiation and the probability of accidental exposures are as low as reasonably achievable. Therefore, radiation dosimetry is required to be done wi

6. Julgamento dos recursos repetitivos nos tribunais superiores : uma nova leitura do princípio da inafastabilidade da jurisdição.
The law being the instrument used by state to organize social relations feeds upon this (social) reality in order to shape its terms and content. Thus the Law must respond to the demands and needs of the society it regulates. Otherwise it would not need be. Based on this idea the Judicial Process while a state instrument used in the making of norms and the p

7. Methodology for DSC calibration in high heating rates
Abstract Despite the large use of differential scanning calorimetry (DSC) technique in advanced polymer materials characterization, the new methodology called DSC in high heating rates was developed. The heating rate during conventional DSC experiments varying from 10 to 20ºC.min-1, sample mass from 10 to 15mg and standard aluminum sample pan weighting, app

8. Uso da região espectral de sobretons para determinação do teor de biodiesel e classificação de misturas diesel/biodiesel adulteradas com óleo vegetal / Using overtone regions to determine biodiesel content and classification of diesel/biodiesel blends adulterated with vegetable oils
This work evaluates the use of overtone regions (NIR) for the classification and determination of biodiesel content in diesel/biodiesel blends adulterated with vegetable oil. For this purpose, NIR spectra were obtained using three different optical paths: 1.0 mm (9000-4000 cm-1); 10 mm (9000-6300 cm-1) e 50 mm (7500-6300 cm-1). Principal Component Analysis (

12. A técnica de difração de elétrons retro-espalhados (EBSD) em microscópio eletrônico de varredura (MEV) e sua aplicação no estudo de rochas deformadas
The electron backscattered diffraction technique in the scanning electron microscope (EBSD/SEM) is based on the diffraction of a high-energy electron beam by the crystalline structure of a given material, in all possible directions within the sample. Some of the diffracted electrons escape from the specimen with virtually the same initial energy, interact wi
