Breast magnetic resonance imaging: A computer-based analysis of enhancement curves

Description : The aim of this work is to report our experience in contrast-enhanced magnetic resonance (MR) automatic analysis. This technique is usually used in our practice for the diagnosis of breast cancer. Study execution and semiautomatic data analysis require at least 1 hour of the radiologist. So, we deci...

Effects of pinacidil on guinea-pig isolated perfused heart with particular reference to the proarrhythmic effect.

Description : 1. The effects of pinacidil (10, 30, 50 microM) on contractility (+dP/dtmax), coronary perfusion pressure (cP), and ECG intervals (PR, QRS, QT) have been studied on constant-flow perfused guinea-pig hearts, driven at four frequencies (2.5, 3, 3.5, 4 Hz). 2. Pinacidil decreased +dP/dtmax, cP and the ...

Optical spectroscopy of Eu3+ doped zinc borate glasses

Description : Zinc borate binary glasses of composition 4ZnO.3B2O3 undoped and doped with 0.5% mol of Eu3+ were prepared from the melt giving rise to samples of excellent optical quality. In the present work we use the spectroscopic properties of the Eu3+ to obtain information about the structural and dynamic fea...

Site distribution and thermalization effects in europium-doped silica glasses

Description : For the no-phonon transition 5D0 → 7F0 of Eu3+ in glasses, obtained by sol-gel route, emission and absorption at low temperature are not resonant. This effect is interpreted by a redistribution of the excitation energy among the different environment for the Eu3+ ion. A simple model is used to inter...

Results from the research program MAP-FASES: investigation of the adsorption kinetics and the dilational rheology of non-ionic surfactants on board the Space Shuttle Columbia during the mission STS-107

Description : Understanding the influence of adsorption kinetics and of the surface rheological properties of surfactants layers on the stability of foams and emulsions is a challenging scientific task and an important technological need. The research programme "Fundamental and Applied Studies in Emulsion Stabili...

Interfacial Rheological Properties of Different Mixed Surfactant-Nanoparticles Surface Layer

Description : The utilisation of solid micro/nanoparticles particles, in some cases in association with surfactants, represents an attractive route to control drop/bubble coalescence or liquid film stability in foam and emulsion technology. Even if rather important for these applications, bubble or drop interfaci...

CoMo/carbon hydrodeoxygenation catalysts: influence of the hydrogen sulfide partial pressure and of the sulfidation temperature

Description : This work concerns the influence of the hydrogen sulfide partial pressure and the sulfidation temperature on the hydrodeoxygenation activity and selectivity of a CoMo catalyst supported on activated carbon. An attempt is made to identify the active sites involved in the reaction of different oxygena...

STRUCTURE AND CRYSTALLIZATION OF FLUOROZIRCONATE GLASSES. STUDY BY THE FLUORESCENCE OF Pr3+ IONS

Description : The 1D2→3H4 fluorescence in fluorozirconate glasses has been studied in non-heated and heated samples. From spectra and decays, several informations were obtained. Two types of crystals grow in this glass. By thermal treatment at Tg a demixtion of the constituants appears. It was impossible to obtai...
