We introduce a charging and accounting (CA) architecture for IP multicast services with QoS guarantees over ATM for QoS-sensitive fair charging. The architecture is based on an extension of the Multicast Integration Server (MIS, [SaCS97]) that efficiently provides IP multicast over ATM, supporting Internet Integrated Services (IS) with receiver(More)
PURPOSE Colorectal cancer (CRC) is the second most common malignancy and the third leading cause of cancer deaths in Israel; it is less common among the Arab than the Jewish population. This study compares the clinico-pathologic features, treatment, and prognosis between Bedouin-Arab (BA) and Jewish CRC patients treated at our medical centre. METHODS The(More)
Mixed-matrix membranes based on amorphous and semi-crystalline polyimides with zirconium dioxide (ZrO2) nanostars were synthesized. Amorphous poly(4,4′-oxydiphenylenepyromellitimide) and semi-crystalline polyimide prepared from 1,4-bis(4-aminophenoxy)benzene and 4,4’-oxydiphthalic anhydride were used. The effect of ZrO2 nanostars on the structure and(More)
The study was undertaken to enhance the efficiency of diagnosis of breast cancer shown up as calcium micromasses since breast diseases appear as clusters of 50-600-um calciferous inclusions that are not inclined to the formation of conglomerates without a visible node on a X-ray film, may be a manifestation of both sclerosing adenosis and nonpalpable(More)
UNLABELLED Comparison of immediate angiographical and clinical results of direct coronary stenting and stenting after predilation was carried out in 68 patients. Groups of patients subjected to direct stenting and stenting with predilation had similar clinical and angiographical characteristics. Direct stenting was successful in 100%, stenting with(More)
A complex methods was used to examine 39 females with the microcalcinates grouped in the breast. The diagnostic efficiency of a number of mammographic and sonographic signs was comparatively evaluated. Ultrasonography was shown to be advisable in differentially diagnosing cancer and sclerosing adenosis. A combination of mammography and sonography may(More)
The study was undertaken to compare the data of quantitative angiographic analysis of early and late outcomes of intracoronary stenting (ICS) and balloon coronary angioplasty (BCA) with the X-Ray morphology of restenosis. The prospective study enrolled 67 patients undergone repeated coronary angiography 2-10 months after successful BCA. Group I included 34(More)
