25. PROCEDIMENTO EXPERIMENTAL PARA AVALIAÇÃO METROLÓGICA DO DESEMPENHO DE UMA MICROTURBINA UTILIZADA PARA GERAÇÃO DE ENERGIA ELÉTRICA / EXPERIMENTAL PROCEDURE FOR A METROLOGICAL EVALUATION OF THE PERFORMANCE OF A MICROTURBINE USED FOR ELECTRIC ENERGY GENERATION
The use of technologies for increasing distributed electric energy generation, particularly gas fired microturbines, has been lately growing due to the energies crisis many countries, including Brasil, have experienced, which is an incentive to an independent electric energy production. Procedures have been developed to check microturbine performance data fo

26. PERFORMANCE OF IN-LINE INSPECTION TOOLS AND ITS INFLUENCE ON THE STRUCTURAL RELIABILITY OF CORRODED PIPELINE / DESEMPENHO DAS FERRAMENTAS DE INSPEÇÃO EM LINHA E SUA INFLUÊNCIA NA CONFIABILIDADE ESTRUTURAL DE DUTOS CORROÍDOS
This work presents: i) the assessment of in line inspection (ILI) tools performance in the measurement of defects caused by corrosion; ii) differents methods to calculate structural reliability and probability of failure (POF) of corroded pipeline based in the ILI report. The inspection report of the ILI (or instrumented pig) is compared with the the geometr

27. NONYLPHENOL POLYETHOXYLATE AND TEXTILE WASTEWATER DEGRADATION BY ELECTROCOAGULATION AND FENTON PROCESSES / DEGRADAÇÃO DE NONILFENOL POLIETOXILADO E DE EFLUENTE TÊXTIL POR MEIO DE ELETROCOAGULAÇÃO E PROCESSOS FENTON
Nonylphenol polyethoxylates are nonionic surfactants widely employed on textile industry. Submitted to inadequate effluent treatment processes, these compounds can be eventually biodegraded to metabolites with estrogenic activity. Therefore, efficient processes on increasing the biodegradability or for the removal of these metabolites became necessary. In th

28. Metodologia para caracterizaÃÃo do desempenho de unidades de ar condicionado tipo janela
The aim of this work is to evaluate the functioning conditions of window air conditioning units through a methodology to characterize their performance. With this purpose, a climatized essay tunnel (TEC) was planned and built, attending the pattern and norms of ABNT (Brazilian Association of Technical Standards) to test window air conditioning units. The dev

29. Visões das gerências da auditoriainterna da Petrobras sobre a sua estratégia de atuação em facedas práticas de mercado e da nova modelagem organizacional da companhia
The purpose of this study is to identify the strategic vision of the Internal Audit Department of Petrel Brasileiro S.A. PETROBRAS, in comparison with the audit function's proposals and practices in competitive organizations and their reality. It also aims at the verification of the possible solutions, within Petrobras itself, so as to constantly add value t

30. ESTUDO COMPARATIVO DA CAPACIDADE PREDITIVA DE MODELOS DE ESTIMAÇÃO DE VOLATILIDADE / A COMPARATIVE STUDY OF THE FORECAST CAPABILITY OF VOLATILITY MODELS
The risk concept is defined as the distribution of the unexpected results from variations in the values of the variables that describe the market. However, the variable risk is not observable and its measurement depends on which model is used in its evaluation. Thus, the application of different models could result in significant different risk forecasts.The

31. Improved Version 2.0 Qualitative and Quantitative AMPLICOR Reverse Transcription-PCR Tests for Hepatitis C Virus RNA: Calibration to International Units, Enhanced Genotype Reactivity, and Performance Characteristics
Version 2.0 qualitative and quantitative AMPLICOR reverse transcription-PCR tests for HCV were designed to improve on the performance of first version of the hepatitis C virus (HCV) tests. The new tests were calibrated in international units, the new commonly accepted standard unit of measurement for HCV RNA. The sensitivity of the qualitative tests was enha

32. Arm function after stroke. An evaluation of grip strength as a measure of recovery and a prognostic indicator.
The value of strength of voluntary grip as an indicator of recovery of arm function was assessed by testing 38 recent stroke patients using a sensitive electronic dynamometer, and comparing the results with those from five other arm movement and function tests (Motricity Index, Motor Club Assessment, Nine Hole Peg Test, and Frenchay Arm Test). This procedure

33. Assessment of HCFA's 1992 Medicare hospital information report of mortality following admission for hip arthroplasty.
OBJECTIVE. The Health Care Financing Administration (HCFA) produced annually from 1987 through 1994 mortality data information as part of the Medicare Hospital Information Project (MHIP) report. We assessed the validity of these data for hip arthroplasty for one state Medicare population and we analyzed the accuracy of the predictions derived from the Bailey

34. Adult polycystic liver disease: is fenestration the most adequate operation for long-term management?
OBJECTIVE: The aim of this study was to evaluate the immediate and long-term results in a retrospective series of patients with highly symptomatic adult polycystic liver disease (APLD) treated by extensive fenestration techniques. A classification of APLD was developed as a stratification scheme to help surgeons conceptualize which operation to offer to pati

35. Characterization of tablet film coatings using a laser-induced breakdown spectroscopic technique
Laser-induced breakdown spectroscopy (LIBS) was evaluated as an early phase process analytical technology (PAT) tool for the rapid characterization of pharmaceutical tablet coatings. Measurement of coating thickness, uniformity, and photodegradation-predictive potential of the technique were evaluated. Model formulation tablets were coated with varying amoun

36. Intracellular Nucleotides of (−)-2′,3′-Deoxy-3′-Thiacytidine in Peripheral Blood Mononuclear Cells of a Patient Infected with Human Immunodeficiency Virus
An analytical methodology was developed to quantitate the intracellular nucleotides including mono-, di-, and triphosphates and the diphosphocholine derivative of (−)-2′,3′-deoxy-3′-thiacytidine (3TC) in human peripheral blood mononuclear cells (PBMCs). The procedure includes the resolution of 3TC nucleotides by solid-phase extraction (SPE) on an ani
