1. Laser aleatÃrio por conversÃo ascendente de freqÃÃncia em neodÃmio
Nesta dissertaÃÃo sÃo apresentados resultados experimentais que demonstram a operaÃÃo de um laser aleatÃrio constituÃdo por um meio fortemente espalhador que contÃm partÃculas dopadas com Ãons de neodÃmio. As partÃculas, de formas irregulares e tamanho da ordem de 30 m, foram obtidas apÃs pulverizarmos vidros fluoroindatos dopados com trÃs dife

2. Development of a supercritical extraction pilot plant for upgrading of heavy oils and study of the asphaltene aggregation process / Desenvolvimento de uma planta piloto de desasfaltação supercritica para valoração de petroleos pesados e estudo do processo de agregação dos asfaltenos
Alphaltenes are complex aromatic macro-cycle molecules, with a molecular structure that varies depending on the origin of the crude oil. Apart from heir contribution to the properties of petroleum, the study of the asphaltic fraction asbecome more important, due to the problems encountered during petroleum Pro cessing caused by asphaltene precipitation, whic

3. Thermal effects on light emission in Yb3+-sensitized rare-earth doped optical glasses
The temperature effect upon infrared-to-visible frequency upconversion fluorescence emission in off-resonance infrared excited Yb3+-sensitized rare-earth doped optical glasses is theoretically and experimentally investigated. We have examined samples of Er3+/Yb3+-codoped Ga2S3:La2O3 chalcogenide glasses and germanosilicate optical fibers, and Ga2O3:La2O3 cha

4. A dynamic, cytoplasmic triacylglycerol pool in enterocytes revealed by ex vivo and in vivo coherent anti-Stokes Raman scattering imagings⃞
The absorptive cells of the small intestine, enterocytes, are not generally thought of as a cell type that stores triacylglycerols (TGs) in cytoplasmic lipid droplets (LDs). We revisit TG metabolism in enterocytes by ex vivo and in vivo coherent anti-Stokes Raman scattering (CARS) imaging of small intestine of mice during dietary fat absorption (DFA). We dir
