2. Electrosynthesis and characterizations of polypyrrole-2-carboxylic acid for application as amperometric biosensor constructed in microelectrodes / Eletrossíntese e caracterização de filmes de polipirrol-2-ácido carboxílico para uso em biossensores amperométricos construídos em eletrodos miniaturizados
In this work, we present the electrochemical synthesis of a new conducting polymer derived of polypyrrole (PPI) functionalized by carboxylic group, the polypyrrole-2-carboxylic acid, and its application as amperometric transducer in biosensor by use of polyphenol oxidase (PFO). All the steps of syntheses and characterization of the polymer film in microelect

4. STATISTICAL METHODOLOGY FOR ANALYTICAL METHODS VALIDATION APPLICABLE CHEMISTRY METROLOGY / METODOLOGIA ESTATÍSTICA PARA VALIDAÇÃO DE MÉTODOS ANALÍTICOS APLICÁVEL À METROLOGIA EM QUÍMICA
The use of statistical methodology for analytical methods validation is vital to assure that measurements have the quality level required by the goal to be attained. This thesis describes a statistical modelling approach for combining four different aspects of validation: checking the linearity of the calibration curve and compute the detection and the quant

5. Straight Line detection revisited: Through the eyes of the spider. / Revendo o problema da detecção de retas através dos olhos da aranha.
Visão é um processo que envolve uma grande quantidade de informações, as quais precisam ser otimizadas de alguma forma para propiciar um processamento eficiente. Grande parte das informações visuais estão contidas nos contornos de uma imagem e uma grande redução no volume dos dados pode ser conseguida com a análise dos contornos. Além dos contorno

7. Immunofluorescence in the Study of Marek's Disease: I. Detection of Antigen in Cell Culture and an Antigenic Comparison of Eight Isolates 1
The indirect fluorescent-antibody (FA) test was applied to the detection of Marek's disease (MD) antigen in cell culture and antibody in the serum of birds. For the detection of antigen, sera were obtained from birds hyperimmunized with the JM strain of MD. MD antigen could be detected in the nucleus and in the cytoplasm of duck and chick embryo fibroblasts

8. Vascular permeability activity in Escherichia coli heat-stable enterotoxin.
Purified heat-stable enterotoxin (ST) prepared from supernatants of Escherichia coli strain 53402 A-1, isolated from a patient with diarrhea, caused an increase in the permeability of the small blood vessels of the skin of adult rabbits after intracutaneous injection. Increased permeability was manifested by localized accumulation of intravenously injected b

9. Genome-Wide Molecular Clock and Horizontal Gene Transfer in Bacterial Evolution
We describe a simple theoretical framework for identifying orthologous sets of genes that deviate from a clock-like model of evolution. The approach used is based on comparing the evolutionary distances within a set of orthologs to a standard intergenomic distance, which was defined as the median of the distribution of the distances between all one-to-one or

10. Magnetic resonance imaging of perfusion using spin inversion of arterial water.
A technique has been developed for proton magnetic resonance imaging (MRI) of perfusion, using water as a freely diffusable tracer, and its application to the measurement of cerebral blood flow (CBF) in the rat is demonstrated. The method involves labeling the inflowing water proton spins in the arterial blood by inverting them continuously at the neck regio
