1. Modelagem e simulação do crescimento de Talaromyces flavus em abacaxi: uma integração entre modelos cinéticos e de fenômenos de transporte
Resumo O estudo da dinâmica de crescimento de microrganismos em alimentos é de vital importância para a extensão da vida de prateleira desses produtos. No presente trabalho, um modelo de cinética microbiológica descrevendo o crescimento de Talaromyces flavus em abacaxi foi integrado com um modelo térmico. O modelo integrado foi utilizado para simular

2. Castor polyurethane used as osteosynthesis plates: microstructural and thermal analysis
Abstract Bone fractures to be corrected need stabilization of their extremities, which is achieved with the use of plates and screws. This research aimed to produce castor bean polyurethane (Ricinus communis), to make resorbable plate, structural and thermal analysis. The production was made by the glycerolysis of the triglycerides present in the oil, after

4. Análise Acústica de Fachadas de Light Steel Frame e Placas Cimentícias
RESUMO A construção a seco tem sido considerada uma alternativa tecnológica aos sistemas construtivos convencionais e, no Brasil, sistemas como o Light Steel Frame e Drywall passaram a ser empregados em maior escala nos últimos anos. Basicamente, estes sistemas consistem em painéis estruturados por perfis de aço, preenchidos internamente por uma lã de

5. Estudo dos Parâmetros de União por Difusão do Aço Inoxidável AISI 316L
Resumo A união por difusão é uma técnica de união no estado sólido capaz de ligar dois materiais metálicos por meio da difusão atômica na interface de contato, sem o uso de metal de adição. Este processo é adequado para a união de grandes áreas com uma alta resistência mecânica, permitindo ao equipamento operar com elevadas pressões de traba

6. Finite element evaluation of the effects of curvature in Lamb waves for composites structural health monitoring
Abstract This work presents the effect of the high curvature to thickness ratio on the characteristics of Lamb Waves propagating over the skins of composite structures. It is accessed how the curvature on composite skins affects the group velocity of the symmetrical (S0) and asymmetrical (A0) wave modes. It is also accessed the gradient of curvature effect,

7. Estudio del comportamiento de fundición CADI sometida a FCR
ABSTRACT Ductile Iron (DI) is a development of the iron alloys introduced in the ´50s, with free graphite in the form of nodules. Austempered Ductile Iron (ADI) is a development of DI later introduced, consisting on austempering heat treatment in order to obtain a high strength and high toughness material. Carbidic Austempered Ductile Iron (CADI) is a more

8. Numerical analysis of truss systems with stiffened flattened end-bars
Abstract Circular hollow sections are usually used in long-span roof truss systems. One of the typology for connecting elements in such structures involves the flattening of bar ends. This article presents the numerical analysis of a plane truss composed of circular hollow sections, in which diagonal bars have flattened ends. In this sense, a new flattening

9. Physical Vapor Deposited Films of a Perylene Derivative: Supramolecular Arrangement and Thermal Stability
The analysis of supramolecular arrangement is essential to understand the role of this key factor on the optical and electrical properties of organic thin films. In this work, thin solid films of bis(phenethylimido) perylene (PhPTCD) fabricated using physical vapor deposition (PVD) technique (thermal evaporation), deposited simultaneously onto different subs

10. Numerical Study on Steel Shear Walls with Sinusoidal Corrugated Plates
Abstract Over the past decades a growing demand and interest has stimulated many researchers to investigate different aspects of steel plate shear walls (SPSWs). The structural performance of steel shear walls with sinusoidal corrugated plate infills is investigated in this study. Finite element (FE) analysis was adopted using ANSYS software, wherein flat an

11. Mixed biofilms formed by C. albicans and non-albicans species: a study of microbial interactions
Abstract Most Candida infections are related to microbial biofilms often formed by the association of different species. The objective of this study was to evaluate the interactions between Candida albicans and non-albicans species in biofilms formed in vitro. The non-albicans species studied were:Candida tropicalis, Candida glabrata andCandida krusei. Singl

12. STEADY STATE AND PSEUDO-TRANSIENT ELECTRIC POTENTIAL USING THE POISSONBOLTZMANN EQUATION
A method for analysis of the electric potential profile in saline solutions was developed for systems with one or two infinite flat plates. A modified Poisson-Boltzmann equation, taking into account nonelectrostatic interactions between ions and surfaces, was used. To solve the stated problem in the steady-state approach the finite-difference method was used
