1. Modulation of drug resistance and biofilm formation of Staphylococcus aureus isolated from the oral cavity of Tunisian children
Abstract Objectives: This study aims to investigate the antimicrobial and the anti-biofilm activities of Lactobacillus plantarum extract (LPE) against a panel of oral Staphylococcus aureus (n = 9) and S. aureus ATCC 25923. The in vitro ability of LPE to modulate bacterial resistance to tetracycline, benzalchonium chloride, and chlorhexidine were tested also

2. ESTIMAÇÃO DE FASORES NA PRESENÇA DE HARMÔNICOS, DECAIMENTO CC EXPONENCIAL E INTER-HARMÔNICOS EXPONENCIALMENTE AMORTECIDOS
This thesis presents the proposition of two novel methods in the field of phasor estimation. The first proposes to estimate the phasor of the fundamental component in the presence of harmonics and exponential decaying DC. This methodology is based on the application of filters DFT (Discrete Fourier Transform) and some methods of signal processing such as win

3. Impact of genetic polymorphism of endothelial nitric oxide synthase on vascular reactivity and adaptation of autonomic modulation to training with physical exercise and diet / Impacto de polimorfismos genéticos da enzima óxido nítrico sintase endotelial sobre as adaptações da reatividade vascular e modulação autonômica a treinamento com exercícios físicos e dieta
Há grande variabilidade inter-individual nas adaptações cardiovasculares a treinamento com exercícios físicos e dieta, provavelmente devido a variações genéticas. Portanto o objetivo geral desta tese foi investigar o impacto de variações no gene da enzima óxido nítrico sintase endotelial (eNOS) sobre adaptações da reatividade vascular e modula�

4. Estabilização de oscilações de potencia de linhas de intercambio atraves de um elo de corrente continua / Stabilization of power lines interchange oscillations through a direct-current link
When an interconnected alternate-current power system suffers variations of loads, its frequency can exhibit an oscillatory behavior. If this system possesses a direct-current link in parallel with the inter-tie lines, this effect could be decreased, due to the link current controller action. This work presents a study that evaluates the efficiency of DC lin

5. Retina de aves como sistema circadiano e sua modulação por luz e glutamato / Avian retina as a circadian system and its modulation by light and glutamate
The avian circadian system is composed by the retina, the mammalian homolog region of the supra-chiasmatic nucleus (SNC) and the pineal gland. The retina itself shows many rhythmic physiological events, such as movements of photoreceptor cells, opsin expression, retinaldehyde re-isomerization, melatonin and dopamine production and release. Altogether these r

6. Schistosomal granuloma as a system adaptive complex. Application of fractal dimension in characterization of their geometric properties. / Granuloma esquistossomótico como um sistema adaptativo complexo. Aplicação da dimensão fractal na caracterização de suas propriedades geométricas.
Schistosomal granuloma AS A COMPLEX ADAPTIVE SYSTEM: APPLICATION OF FRACTAL DIMENSION IN THE CHARACTERIZATION OF PROPERTIES GEOMETRIC. Waldemiro de Souza Romagna. [Introduction]. The schistosomal granuloma is a compact, organized collection of migrating cells, which along with cells of the affected organ, arrange themselves in the midst of extracellular matr

7. Estudo de amplificadores parametricos para sistemas de comunicações opticas de altas taxas de transmissão / Study of parametric amplifiers for high bit rate optical communication systems
This thesis presents a theoretical and experimental study on fiber optics parametric amplifiers. For the double-pumped case, we show the performance of the amplifier in terms of spectral bandwidth and gain uniformity, both fundamental properties for WDM applications. By using short dispersion shifted fibers and highly non-linear fibers, we made parametric am

8. Comparação entre diferentes metodologias para detecção do limiar de anaerobiose durante exercício físico em cicloergômetro de homens saudáveis e com infarto do miocárdio.
The objectives of this study were: to determine AT of healthy (HI) and coronary disease (CD) men by ventilatory visual method (gold standard) and by means of Hinkley statistical method applied to heart rate (HR), carbon dioxide output ( CO2) and surface electromyography (sEMG) root mean square (RMS) data, and to compare both methods in each studied group; to

9. Estudo Analítico e numérico de um enlace digital de comunicação via satélite em condição orbital geo-estacionária / Analytical and numerical analysis of a digital communication geostationary satellite link.
The links of satellites are affected by propagation conditions and distortions that are generated by devices. The propagation losses as well as the passive components attenuation are very simple to analyze, but many calculations involved with the complete link demand to discover the carrier to inter-modulation ratio. This work presents an innovative set of e

10. Nitric oxide, cGMP, and hormone regulation of active sodium transport.
The inter- and intracellular regulator nitric oxide (NO) has been suggested to play a role in the modulation of cellular excitability, but the mechanism(s) by which this occurs remain unclear. Using the kidney as a model system, we report here evidence that NO, produced in response to various hormones and cytokines, can effect long-term alterations in the ac

11. Modulation of oligonucleotide duplex and triplex stability via hydrophobic interactions.
Synthetic oligonucleotides have been proposed as a new rationally designed class of pharmaceuticals with a mechanism of action based upon a Watson-Crick and/or Hoogsteen type of base pairing with RNA or DNA regions of interest. Two series of 3'-cholesterol and/or 5'-cholesterol conjugated oligonucleotides have been synthesized. The primary structure of these

12. Responses of macaque ganglion cells to the relative phase of heterochromatically modulated lights.
1. We measured the response of macaque ganglion cells to sinusoidally modulated red and green lights as the relative phase, theta, of the lights was varied. 2. At low frequencies, red-green ganglion cells of the parvocellular (PC-) pathway with opponent inputs from middle-wavelength sensitive (M-) and long-wavelength sensitive (L-) cones were minimally sensi
