3. AN EVALUATION OF THE THERMAL AND LUMINOUS ENVIRONMENT OF LAYING HEN AVIARIES EQUIPPED WITH LIGHT-EMITTING DIODE AND COMPACT FLUORESCENT LAMPS AND THEIR EFFECTS ON PRODUCTION AND EGG QUALITY
ABSTRACT The thermal and luminous conditions in aviaries affect the production and quality of eggs. Thus, the aim of the present study was to evaluate the thermal and luminous environment of commercial laying hen aviaries equipped with compact fluorescent (CF) and light-emitting diode (LED) lamps and their influence on egg production and quality. The study w

6. Avaliação de desvio dimensional em Inconel 718 após a retificação em diferentes técnicas de lubri-refrigeração
RESUMO O Inconel 718 é uma liga à base de níquel que possui elevada resistência à fadiga e à fluência, ductilidade, rigidez, inércia química e capacidade de operar em elevadas temperaturas, por isto é bastante utilizada na fabricação de peças aeronáuticas de alto rendimento. Estas peças exigem tolerâncias dimensionais e geométricas estreitas

7. Silver nanoparticles incorporated PVC films: evaluation of structural, thermal, dielectric and catalytic properties
Abstract In this work, silver nanoparticle – polyvinylchloride (SNC-PVC) composites were synthesized by loading 2.5% to 10.0% silver ions to PVC using simple solution casting technique. Material properties including dielectric, thermal stability were discussed in some detail. Incorporation of silver nanoparticles (SNPs) in the PVC matrix was confirmed by U

8. Biomechanical development and evaluation of a new framework for all-on-four rehabilitation
Resumo Introdução Para reabilitação de mandíbulas totalmente edêntulas, a opção por carga imediata determina a utilização de próteses provisórias que esplintem os implantes instalados. Apesar de provisórias com reforço proverem as reabilitações com benefícios biomecânicos, a não adoção desta indicação coexiste em diferentes estudos so

9. Modelagem da transferência de calor de ambientes subterrâneos no programa de simulação EnergyPlus
Resumo A temperatura do solo é um dos fatores mais influentes nas avaliações de desempenho térmico de ambientes subterrâneos e quase sempre é desconsiderada. Por isso, é necessário avaliar essa influência devido à interação do solo com a edificação, pois a transferência de calor através de paredes e pisos subterrâneos tem uma extensão signi

10. Performance Evaluation of Titanate Nanotubes and Nanoribbons Deposited by Electrophoresis in Photoelectrodes of Dye-Sensitized Solar Cells
Nanoparticles of TiO2 have been the main semiconductor applied in Dye-sensitized solar cells (DSSCs). In this work, titanate nanotubes (NaTiNT) and nanoribbons, were obtained by the hydrothermal method from TiO2 anatase. These materials were deposited on conductive substrate by electrophoresis, with and without thermal treatment, sensitized by ruthenium-base

11. Thermographic Images to Measure Health Risks of Workers Exposed to Artificially Refrigerated Environments
ABSTRACT Thermography generates high-resolution imagery in real time and is a non-invasive and painless technique devoid of physical contact or exposure to any type of radiation. This technique has been successfully applied to different areas, such as health- and safety-related applications, to control cold risk in workers exposed to low-temperature environm

12. FOURIER TRANSFORM INFRARED SPECTROSCOPY, THERMOGRAVIMETRIC ANALYSIS, SCANNING ELECTRON MICROSCOPY AS SUPPORTING TOOLS IN QUALITY CONTROL OF ANTIPARASITICS
This study shows that Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM) can be used as supporting tools for the evaluation of the quality of antiparasitics. In addition, an analytical methodology was developed and validated to quantify simultaneously thiabendazole (TB), febantel (FB), tol
