Retenção de coroas de zircônia: estudo de diferentes condições de tratamento interno de coroas em zirconia e do núcleo em resina composta
(Universidade Federal de Santa MariaBrasilOdontologiaUFSMPrograma de Pós-Graduação em Ciências OdontológicasCentro de Ciências da Saúde, 2017-01-12)
The present thesis was structured in two scientific articles that investigated the adhesion of zirconium oxide ceramic crowns. The first article aimed to evaluate different methods for silica deposition at the inner surface ...
Effect of Ultrasound on the Stability of Turmeric Oleoresin Microencapsulated in Gelatin-Collagen Matrices
(Wiley-Blackwell, 2017-04-01)
This study evaluated the effect of sonication on the stability of turmeric oleoresin microcapsules produced by spray and freeze-drying using blends of gelatin-collagen as encapsulating matrices. Samples prepared with ...
Fish larvae retention linked to abrupt bathymetry at Mejillones Bay (northern Chile) during coastal upwelling events

Ultrasound application for production of nano-structured particles from esterified starches to retain potassium sorbate
(Elsevier, 2020-11)
Ultrasound technique was successfully used to obtain nanostructured particles from native and esterified starch, able to support the antimicrobial potassium sorbate (PS). The starch used (native, acetate or oleate) affected ...
Modelagem Matemática e Computacional do Processo de Filtração em Meios Porosos
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia de Petróleo, 2017-11-24)
This final paper approaches a problem associated with fluid flow, transport and retention of particles in oil reservoirs. Such phenomenon is commonly refereed as deep bed filtration. The filtration phenomenon occurs in ...
Filtração de gases: estudo da deposição de diferentes tortas de filtração em diferentes meios filtrantes
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2006-06-19)
The particle retention inside a filter medium, after cleaning, significantly improves the
initial pressure drop during the subsequent cycle, that is, the residual pressure drop.
However, the way as these particles ...
Laser-induced breakdown spectroscopy to determine soil texture: A fast analytical technique
(2016-02-01)
The analysis of soil texture is crucial for the proper management of agricultural systems and for environmental studies. Soil texture is important as it affects erosion potential, water retention capacity, organic matter ...
Modelagem matemática para o transporte de partículas sujeitas a múltiplos mecanismos de retenção
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2013-09-13)
Discrepancies between classical model predictions and experimental data for deep bed filtration have been reported by various authors. In order to understand these discrepancies, an analytic continuum model for deep bed ...
