1. Undiagnosed acute HIV infection identified through RNA testing of pooled serum samples obtained during a dengue outbreak in São Paulo, Brazil
Abstract INTRODUCTION: Improving HIV diagnostics and treatment is necessary to end the AIDS epidemic. Pooled plasma can be used to identify patients with acute HIV disease, even before serological tests. During dengue outbreaks, patients having symptoms common to other acute viral diseases might seek medical care. METHODS: We evaluated HIV RNA in pooled s

2. O líquido cefalorraquidiano pode ser usado para a genotipagem do HIV quando esta não é possível no plasma
O plasma é a amostra clínica padrão utilizada para a genotipagem da região pol do HIV-1; entretanto, a genotipagem pode nem sempre ser bem sucedida, geralmente devido a baixas cargas virais ou à presença de inibidores da reação em cadeia da polimerase (PCR). Objetivo: Descrever o sucesso da genotipagem do HIV-1 em duas amostras de líquido cefalorr

3. A new method for surface modifications of carbon steels and alloys
A three-dimensional treatment method involving implantation of ions into solids immersed in a high voltage pulse discharge ignited on the left-hand-branch of the Paschen curve was elaborated about fifteen years ago. This method, named 3DII for short, has been used in the equipment JUPITER (Joint Universal Plasma and Ion Technologies Experimental Reactor) for

4. The use of molecular spectra simulation for diagnostics of reactive flows
Abstract: The C2* radical is used as a system probe tool to the reactive flow diagnostic, and it was chosen due to its large occurrence in plasma and combustion in aeronautics and aerospace applications. The rotational temperatures of C2* species were determined by the comparison between experimental and theoretical data. The simulation code was developed by

5. Optical and electrical diagnostics of microdischarges at moderate to high pressure in argon
Microdischarges at moderate to high pressure in argon were investigated. A hole opening diameter of 500 µm direct current (dc) microhollow cathode discharges (MHCD) were characterized by electrical measurements and optical emission spectroscopy (OES) for pressures ranging between 90 and 800 Torr and current from 5 to 20 mA. Current-voltage characteristic cu

6. Medidas da temperatura e densidade eletronica utilizando a unicidade do tempo de confinamento de particulas no Tokamak NOVA-UNICAMP / Electronic density and temperature measurements using the particle confinement time iniqueness in the NOVA-Tokamak
In this work, we have made simultaneous measurements of three hydrogen emission lines on our tokamak. From the measurements of absolute brightness of the Ha , H b e Hg lines an using data from Johnson an Hinnov table, was possible to determine electronic ensities an temperatures during the tokamak ischarges. For this,we have used, an refined, a technique dev

8. Study of the interaction of the electric arc with cold copper cathode in air and nitrogen using the thermo-spectroscopic diagnostic technique / Estudo da interação de arcos elétricos com catodo frio de cobre para ar e nitrogenio utilizando a tecnica de diagnostico termo-espectroscopica
Uma nova técnica de diagnóstico, denominada termo-espectroscópica, foi introduzida neste trabalho para estudo da interação do arco elétrico com o catodo frio de cobre numa instalação coaxial magnética, com catodo não-refrigerado, operando em gases plasmagênicos ar e nitrogênio. A técnica foi aplicada ao estudo da velocidade de rotação da manch

9. Determination fo the configuration of excited Alfvén waves in tokamak TCABR / Determinação da configuração de ondas de alfvén excitadas no tokamak TCABR
In order to enhance the efficiency of the TCABRs Alfvén waves heating system, called AWES - Alfvén Waves Excitement System a diagnostics for determining the radio-frequency power applied to the plasma and a processing circuit for the magnetic coil system was built, characterized, installed and put into operation. The RF diagnostics system was designed to d

10. Fragmento 1+2 da protrombina em indivíduos submetidos à angiografia coronariana
A trombina exerce um papel fundamental na conversão do fibrinogênio em fibrina, no processo de coagulação. O fator X ativado transforma a protrombina em trombina e fragmento 1+2 da protrombina (F1+2). Os níveis plasmáticos de F1+2 refletem a geração de trombina e podem ser usados como um marcador de hipercoagulabilidade in vivo, já que a trombina é

11. Electron Cyclotron Emission in the TCABR Tokamak: An Experimental Study. / "Emissão Eletrociclotrônica no Tokamak TCABR: Um Estudo Experimental"
In this work, an experimental study of the Electron Cyclotron Emission (ECE) in the TCABR Tokamak, is described. An ECE sweeping heterodyne radiometer, operating in the 50-85 GHz frequency range, was installed, calibrated and used to detect ECE radiation in the second harmonic extraordinary mode from thermal plasma discharges. The noise temperature, amplitud

12. First results on the fast neutral lithium beam diagnostics probing the edge plasma of the ETE tokamak
One of the main objectives of the research program at ETE is devoted to the study of confinement properties in a low aspect ratio tokamak plasma configuration, and to attain this purpose the determination of plasma parameters of the edge region plays an essential role. A Fast Neutral Lithium Beam (FNLB) diagnostics was developed to perform the measurement of
