1. Ab initio LSDA+U Study of Optical Properties of RVO4 (R = Eu, Ho, Lu) Compounds
A first principles investigation at the pressure 7 GPa of the optical properties of RVO4 (R= Eu, Ho, Lu) orthovanadates in the framework of the density functional theory (DFT) using the linearized-augmented plane-wave method is reported in order to predict new optical materials for continuous-wave lasers. The electronic structure of all orthovanadates is stu

2. FÃnons nos sistemas RVO4 e La1-xCexPO4 / Phonons in the RVO4 and La1-xCexPO4 systems
Neste trabalho apresentamos uma investigaÃÃo dos compostos RVO4 (onde R = Sm, Ho, Yb e Lu) e La1-xCexPO4 (onde x = 0,00, 0,04, 0,16, 0,22, 0,32 e 1,00) atravÃs da tÃcnica de espalhamento Raman. Medidas de espalhamento Raman polarizadas foram realizadas nos compostos RVO4 para obter uma descriÃÃo dos fÃnons a temperatura ambiente melhor do que aquelas

3. Aqueous flare and cells in eyes with retinal vein occlusion--correlation with retinal fluorescein angiographic findings.
The laser flare cell meter (LFCM) was used to evaluate alterations of the blood-aqueous barrier in eyes with retinal vein occlusion (RVO). In 42 eyes of 42 patients with RVO (30 branch vein occlusions, 12 central vein occlusions) aqueous flare and aqueous cells were determined and retinal fluorescein angiography was performed. Flare and cell values were comp

4. Early ductal shunting and intraventricular haemorrhage in ventilated preterm infants.
AIM: To establish if there is an association between early cardiovascular adaptation and intraventricular haemorrhage (IVH). METHODS: One hundred and seventeen ventilated preterm infants (mean gestational age 27 weeks, mean birthweight 993 g) were studied echocardiographically within the first 36 hours. Measurements included right (RVO) and left ventricular
