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. Growth curves of meat-producing mammals by von Bertalanffy’s model
Resumo: O objetivo desde trabalho foi avaliar como a parametrização e a aplicação de diferentes valores alométricos afetam a obtenção do ajuste mais adequado do modelo de von Bertalanffy, na descrição da curva de crescimento de mamíferos produtores de carne (bovinos, porcos, coelhos e ovelhas). Entre os modelos não lineares, o de von Bertalanffy t

3. Enhancement the Fatigue Life of Floating Breakwater Mooring System Using Tuned Liquid Column Damper
Abstract Safety is a key design criterion for floating structures. A high rate of mooring accidents has been reported over the past decades. Preventing mooring line failure is a key design objective for floating breakwater systems. The mooring system comprises sets of mooring lines anchored to the seabed. These components are exposed to highly cyclic nonline

4. Finite Element Investigation of Performance of Composite-Steel Double Lap Adhesive Joint Under Tensile Loading
Abstract Parametric study of composite-steel double lap joint under tensile loading is performed using finite element modeling. The joint is such that steel is placed between a straight and a curved composite sublaminate. Three joint characteristics including maximum Von Mises stress in adhesive layer, stiffness and weight are investigated. Design curves are

5. Spatial prediction of soil penetration resistance using functional geostatistics
ABSTRACT Knowledge of agricultural soils is a relevant factor for the sustainable development of farming activities. Studies on agricultural soils usually begin with the analysis of data obtained from sampling a finite number of sites in a particular region of interest. The variables measured at each site can be scalar (chemical properties) or functional (in

6. Local/Distortional/Global buckling mode interaction on thin walled lipped channel columns
The buckling behaviour of pin ended cold-formed steel lipped channel columns affected by local / distortional / global buckling mode interaction under axial loading is simulated by using finite element software ABAQUS, and the results are compared with the test results available in the literature. The comparisons show that the proper analysis model can simul

7. Parametric study on average stress-average strain curve of composite stiffened plates using progressive failure method
The post-buckling behavior of composite ships' stiffened plate panels has been studied. In this study, the average strain- average stress curves for these panels are derived using progressive failure method as well as nonlinear finite element method. The boundary conditions are appropriate for the continuous plate panels used in shipbuilding. The effects of

8. Deflection profile analysis of beams on two-parameter elastic subgrade
A procedure involving spectral Galerkin and integral transformation methods has been developed and applied to treat the problem of the dynamic deflections of beam structure resting on bi-parametric elastic subgrade and subjected to travelling loads. The case of the response to moving constant loads of this slender member is first investigated and a closed fo

9. Avaliação do comportamento solo-estrutura de elementos de fundação tipo sapata estaqueada / Assessment of the behavior of soil-structure foundation elements like piled footing
This work aims to study the behavior and interaction between soil, shallow footing and pile, based on the implementation and monitoring of four direct load tests performed on: a single shallow footing, a shallow footing with one pile, a shallow footing with four piles and a pile alone. During the load tests, vertical displacements were monitored at different

10. Population dynamics, life stage and ecological modeling in Chrysomya albiceps (Wiedemann) (Diptera: Calliphoridae)
In this study we investigated the population dynamics of Chrysomya albiceps (Wiedemann) with laboratory experiments, employing survival analysis and stage structure mathematical models, emphasizing survival among life stages. The study also assessed the theoretical influence of density dependence and cannibalism during immature stages, on the population dyna

11. Modelo matemático multigrãos e multifásico para a previsão da solidificação equiaxial. / Multigrain and multiphase mathematical model for prediction of the equiaxed solidification.
Properties of components obtained by solidification processes depend strongly on the final grain structure. In the past few decades, there has been a significant breakthrough in the mathematical modeling of metallic alloy solidification to predict the grain macrostructure. Nevertheless, the so-called deterministic models are still not capable of modeling the

12. Evaluation of 5-axis HSC dynamic behavior when milling TiAl6V4 blades
Gas combustion represents the second principal way of electricity generation due to its disposal, and smaller dimension and pollution capacity when compared with diesel engines. The conversion of natural gas in electricity is made through gas turbines, and the rotors of its compressors are components that present significant difficulty in its manufacture. Th
