In contrast-enhanced DBT (CE-DBT), breast lesion vascularity is characterized by administrating an iodinated vascular contrast agent. In this work, a combined temporal and dual-energy (DE) subtraction CE-DBT technique was performed in 4 women with mammographic findings that warranted biopsy. Lesion enhancement characteristics and morphology obtained with both CE-DBT techniques are correlated to...

Résumé : Dans les folksonomies, les utilisateurs partagent des ressources (films, livres, sites web, etc.) en les annotant avec des tags librement choisis. Dans ce papier, nous considérons une nouvelle dimension dans une folksonomie qui contient des des informations supplémentaires sur les utilisateurs. Nous définissons un degré de proximité entre deux utilisateurs comme le nombre d’information...

Résumé : Ce papier présente la version adaptative d’un algorithme d’extraction d’épisodes temporels développé précédemment. Les trois paramètres de réglages de l’algorithme ne sont plus fixes. Ils sont modifiés en ligne en fonction de la variance estimée du signal que l’on veut décomposer en épisodes temporels. La version adaptative de l’algorithme a été utilisée pour reconnaître automatiquemen...

The kinetic of Fischer-Tropsch synthesis over a co-precipitated Fe-Ce catalyst was investigated in a fixed bed micro reactor. Experimental conditions were varied as follow: reaction pressure 1-15bar, H¬¬¬2/CO feed ratio of 1-3 and space velocity of 3600-5400 h-1 at the temperature range of 270-310°C. 4 models according to the Langmuir-Hinshelwood-Hougen-Watson (LHHW) type rate equation were der...

Abstract In the present study, a facile solvothermal method was used for synthesis of silicotungstic acid (HSiW) immobilized on Ce-based metal organic framework (Ce-BDC) and embedded in Zr-based metal-organic (UiO-66(Zr)) composite catalyst, namely, Ce-BDC@HSiW@UiO-66 production biodiesel through green fatty esterification. The obtained hybrids were characterized by various characterization tec...

Mn-Ce catalysts modified by Mo were loaded on low-density porous ceramics (LDPC) for simultaneous denitrification and dust removal. The Mn-Ce-Mo catalyst LDPC had nearly 99% NOx conversion efficiency from 120 °C to 200 still maintained more than 90% when the filtration velocity reached 4 m/min. catalysts/LDPC not only exhibited excellent catalytic performance at low temperature, they also good ...

wastewater treatment and re-use of industrial process water are critical issues for the developmentof human activities and environment conservation. the present study was undertaken to evaluate the degradationof organic pollutants taking phenol as the model compound over aluminium pillared montmorillonite and therare earth exchanged analogues, underlining the use of environ friendly clay cataly...
