1. Learning curve for endoscopic evaluation of vocal folds lesions with narrow band imaging
Resumo Introdução: Os métodos endoscópicos estão progredindo e se tornando comuns no diagnóstico clínico de rotina também na otorrinolaringologia. Um número relativamente grande de pesquisas demonstrou alta precisão na endoscopia com imagem de banda estreita na diferenciação de lesões benignas e malignas nas pregas vocais. Entretanto, pouco se

2. Uncertainty estimation in hydrodynamic modeling using Bayesian techniques
RESUMO A avaliação de incertezas tem emergido como estudo primordial para se conhecerem os efeitos dos erros inerentes aos processos de modelagem de perfis de escoamento de vazões de cheia, de natureza aleatória e epistêmica, presentes em dados de entrada como vazões e topobatimetria, na estrutura e parametrização dos modelos matemáticos utilizados

3. Soil Organic Carbon Determination Using NIRS: Evaluation of Dichromate Oxidation and Dry Combustion Analysis as Reference Methods in Multivariate Calibration
Dichromate oxidation and dry combustion analysis were evaluated as reference methods to determine organic carbon in Brazilian soils using near infrared spectroscopy (NIRS) as an alternative. The main objective of this study was to evaluate which of the reference methods could provide a calibration model with higher predictive ability. A total of 161 soil sam

4. A STUDY OF PYROLYSIS OF MACADAMIA NUT SHELL: PARAMETRIC SENSITIVITY ANALYSIS OF THE IPR MODEL
Abstract The macadamia tree is known for producing fruit high in fats, enclosed in very hard woody shells. Macadamia nut shell, considered as a by-product from macadamia nut processing, may be a suitable option for pyrolysis. These residues are constituted of cellulose, hemicellulose, lignin and extractives. The Independent Parallel Reaction (IPR) Model has

5. A Sensitivity Investigation on the Aeroelastic Dynamic Stability of Slender Spinning Sounding Rockets
ABSTRACT: The present work addresses a sensitivity analysis investigation of the aeroelastic stability margins for the VSB-30 sounding rocket during the atmospheric flight phase. Parametric stability analyses are performed considering variations of the inertia properties of the modular payload. Such variations can be caused by different type and/or number of

6. Modelling of fertilizer drying in a rotary dryer: parametric sensitivity analysis
This study analyzed the influence of the following parameters: overall volumetric heat transfer coefficient, coefficient of heat loss, drying rate, specific heat of the solid and specific heat of dry air on the prediction of a model for the fertilizer drying in rotary dryers. The method of parametric sensitivity using an experimental design was employed in t

7. Temporomandibular disorders and parafunctional oral habits: an anamnestic study
OBJECTIVE: To assess the frequency and severity of the signs and symptoms of temporomandibular disorders (TMD), the frequency of parafunctional oral habits and the correlation between the variables by means of the patients' perception regarding their problem. METHODS: One hundred patients diagnosed with TMD, through a clinical examination of their masticator

8. Parametric sensitivity analysis for the helium dimers on a model potential
Potential parameters sensitivity analysis for helium unlike molecules, HeNe, HeAr, HeKr and HeXe is the subject of this work. Number of bound states these rare gas dimers can support, for different angular momentum, will be presented and discussed. The variable phase method, together with the Levinson's theorem, is used to explore the quantum scattering proc

9. Uma aplicação de controle preditivo multiparamétrico em planejamento da produção / An application of multi-parametric predictive control in production planning
Nesta dissertação, o problema de controle preditivo baseado em modelo, um problema de otimização não linear com critério de desempenho quadrático e restrições lineares, é reformulado via otimização quadrática multiparamétrica, em que as entradas de controle são as variáveis de otimização e os estados (no caso mais simples) representam um ve

11. Clinical evaluation of desensitizing treatments for cervical dentin hypersensitivity
The aim of this study was to compare different treatments for dentin hypersensitivity in a 6-month follow-up. One hundred and one teeth exhibiting non carious cervical lesions were selected. The assessment method used to quantify sensitivity was the cold air syringe, recorded by the visual analogue scale (VAS), prior to treatment (baseline), immediately afte

12. Aspects of psychosexuality and personality of maleto- female and female-to-male transsexuals evaluated by Szondi projetive test / Aspectos da psicossexualidade e da personalidade de pacientes autodenominados transexuais masculinos e femininos avaliados pelo teste projetivo de Szondi
Transsexualism is a disorder of sexual identity associated with strong and persistent identification with the opposite sex. There are few studies concerning the use of psychological tests as diagnostic tools for transsexualism. The objective of this study was to assess the psychosexual aspects of self-denominated transsexuals through the Szondi test. Retrosp
