A study of the statistics of cosmological black-hole jet sources is applied to EGRET blazar data, and predictions are made for GLAST. Black-hole jet sources are modeled as collimated relativistic outflows with radiation beamed along the jet axis due to strong Doppler boosting. The comoving density dependence of the blazar formation rate (BFR) is assumed to follow the cosmic star formation histo...

Dynamical evolution models of 361 extragalactic Fanaroff–Riley type II radio sources selected from the Cambridge 3CRR, 6CE, 5C6, and 5C7 Sky Surveys, as well Bologna B2, Green Bank GB, GB2 are presented. Their spectra, compiled mostly recent catalogs available NASA/IPAC Astrophysical Catalogs Support System databases, along with morphological characteristics determined their maps, have been mod...

We present results from our optical survey of the position error contours (“error boxes”) of unidentified EGRET sources at mid to high Galactic latitude. It is our intention to search for potential blazars that may have been missed in the original identification process of the three EGRET Catalogues and supplementary publications. We have first searched the error contours of unidentified source...

The GEMS project involves a multi-wavelength study of a sample of 60 galaxy groups, chosen to span a wide range of group properties. Substantial ROSAT PSPC observations, available for all of these groups, are used to characterise the state of the intergalactic medium in each. We present the results of a uniform analysis of these ROSAT data, and a statistical investigation of the relationship be...

objective(s): the aim of this study was to investigate the methylation status and mrna expression levels of p15, death-associated protein kinase (dapk), and suppressor of cytokine signaling-1 (socs1) genes in multiple myeloma (mm). materials and methods: the bone marrow samples of 54 mm patients were collected and the methylation status of the p15, dapk, and socs1 gene promoter regions was dete...
