In order to determine the epidemiology of adult scoliosis in the elderly and to analyse the radiological parameters and symptoms related to adult scoliosis, we carried out a prospective cross-sectional radiological study on 1347 adult volunteers. There were 615 men and 732 women with a mean age of 73.3 years (60 to 94), and a mean Cobb angle of 7.55 degrees (sd 5.95). In our study, 478 subjects...

We present the first results from an XMM-Newton observation of RX J1347.5−1145 (z=0.451), the most luminous X-ray cluster of galaxies currently known, with a luminosity LX = 6.0±0.1×10 45 erg s in the [2-10] keV energy band. The cluster has an overall temperature of kT = 10.0 ± 0.3 keV and is not isothermal: the temperature profile shows a decline in the outer regions and a drop in the centre, ...

Semantic optimization of database queries, i.e. the use of metadata (constraints) for query optimization, is well investigated and has led to signi cant performance gains. The algorithm semantically rewriting database queries presented in [2] is applicable to CEP queries with some adaptions. One of these adaptions concerns the treatment of views and the constraints for them. To reduce the numbe...

Bireylerin finansal konularda karar alırken karşılaştığı birçok alternatif risk ile ilişkilendirilmektedir. Bir yatırımcının verme sürecinde karşısında gösterdiği tutum, alma tutumu olarak ifade edilir. Rasyonellik beklentisine rağmen, bireylerin irrasyonel tutum ve davranışlar sergiledikleri bilinmektedir. Bu nedenle yatırımcıların bu davranışlarının altında yatan sebeplerin araştırılması önem...

We use observations of Sunyaev-Zel’dovich effect and X-ray surface brightness to reconstruct the radial profiles of gas temperature and density under the assumption of a spherically symmetric distribution of the gas. The method of reconstruction, first raised by Silk & White, depend directly on the observations of the Sunyaev-Zel’dovich effect and the X-ray surface brightness, without involving...
