Attenuation of dipping at low energies in the LMXB source X 1755 - 338
We report spectral fitting results for Rosat PSPC observations of the dipping source X 1755-338. These results are consistent with the two-component model that we previously proposed consisting of a blackbody point source plus an extended power law component. Remarkably, the low energy cutoff of the spectrum does not change appreciably in dips, and it can be seen that dipping takes place in the...
متن کاملX-ray Spectrum of the Black Hole Candidate X1755-338
We report the rst detection of a hard power-law tail in the X-ray spectrum of the black hole candidate (BHC) binary X1755-338, which was observed in 1989 March-September during the TTM Galactic Centre survey. In addition, an ultrasoft thermal component with a temperature of 1:1 1:4 keV was also detected. We demonstrate that the soft and hard X-ray components of X1755-338 vary independently, as ...
متن کاملEvaluation of the Effect of Source Geometry on the Output of Miniature X-ray Tube for Electronic Brachytherapy through Simulation
Objective: The use of miniature X-ray source in electronic brachytherapy is on the rise so there is an urgent need to acquire more knowledge on X-ray spectrum production and distribution by a dose. The aim of this research was to investigate the influence of target thickness and geometry at the source of miniature X-ray tube on tube output.Method: Five sources were simulated based on problems e...
متن کاملthe impact of skopos on syntactic features of the target text
the present study is an experimental case study which investigates the impacts, if any, of skopos on syntactic features of the target text. two test groups each consisting of 10 ma students translated a set of sentences selected from advertising texts in the operative and informative mode. the resulting target texts were then statistically analyzed in terms of the number of words, phrases, si...
