This study aims to investigate the potential use of LaBr3:Ce and LaCl3:Ce materials in SPECT imaging. GATE Monte Carlo simulations of single-head gamma camera and a Tc point source were performed to evaluate the energy spectra, modulation transfer function (MTF) and detection efficiency. A range of Ce concentrations (0.5, 5, 10 and 15)% of LaBr3:Ce and LaCl3:Ce crystals was simulated in conjunc...

OBJECTIVE The effects of bazedoxifene (BZA)/conjugated estrogens (CE) on sleep and health-related quality of life (HRQoL) were evaluated in nonhysterectomized postmenopausal women who were enrolled in a randomized, double-blind, placebo- and active-controlled phase 3 trial. METHODS The sleep/HRQoL substudy enrolled 459 women with bothersome moderate to severe vasomotor symptoms who were rando...

Prosthetic valve replacement remains the most viable alternative for the treatment of severely diseased heart valves. The cumulative experience of mechanical protheses and bioprostheses was evaluated for a 10-year performance comparison: Carpentier-Edwards standard porcine bioprosthesis (CE-S), 1,214 operations; Carpentier-Edwards supraannular porcine bioprosthesis (CE-SAV), 2,489; and mechanic...

Nous nous centrons dans cette contribution sur l’orthographe pratiquée par les élèves, leurs connaissances du système et l’évolution de ces connaissances. donnons tout d’abord un panorama (non exhaustif) travaux récents conduits la maternelle à l’âge adulte. Puis abordons moyens que pour appréhender, évaluer faire évoluer compétences des élèves. intéressons également aux unités linguistiques él...

conclusion these data indicate that while ce-mri will depict more positive results, there are cases in which dwi will show a positive result while ce-mri is negative. we suggest that the combination of these two imaging modalities might yield more positive results in diagnosing acute ms attack giving rise to a more accurate diagnosis. results ce-mri yielded positive results for 61 (87%) patient...

Over the past few years, Grid Computing technologies have reached a high level of maturity. One key aspect of this success has been the development and adoption of newer Compute Elements to interface the external Grid users with local batch systems. These new Compute Elements allow for better handling of jobs requirements and a more precise management of diverse local resources. However, despit...
