We present results from XMM–Newton observations of the obscured QSO 1SAX J1218.9+2958. We find that the previously reported optical and soft X–ray counterpart positions are incorrect. However we confirm the spectroscopic redshift of 0.176. The optical counterpart has a K magnitude of 13.5 and an R–K colour of 5.0 and is therefore a bright extremely red object (ERO). The X–ray spectrum is well d...

Gadolinium-159 (159Gd) is a beta emitter with appropriate energy for therapeutic application. However, this radioisotope additionally emits gamma rays, enabling the distribution of 159Gd to be detected by camera after each administration. The current research innovative in investigation as theranostic radioembolization HCC using Monte Carlo (MC) simulation. For investigation, various patient sc...

The Monte-Carlo calculations of the Moliere radius (RM) for some homogeneous and heterogeneous media used in electromagnetic calorimetry energy range from 50 MeV to 10 GeV are presented detail. obtained results, uncertainties determining RM, estimations absorbed energy, methods approximating accuracy results discussed as well. Some RM shown calorimeter proto-types Spin Physics Detector experime...

We present the results of a 2-10 keV BeppoSAX survey based on 140 high galactic latitude MECS fields, 12 of which are deep exposures of “blank” parts of the sky. The limiting sensitivity is 5 × 10 erg cmswhere about 25% of the Cosmic X-ray Background (CXB) is resolved into discrete sources. The logNlogS function, built with a statistically complete sample of 177 sources, is steep and in good ag...

The aim of the present Monte Carlo study is to evaluate the variation of energy deposition in healthy tissues in the human eye which is irradiated by brachytherapy sources in comparison with the resultant dose increase in the gold nanoparticle (GNP)-loaded choroidal melanoma. The effects of these nanoparticles on normal tissues are compared between 103Pd and 125I as two ophthalmic brachytherapy...

The use of Computerised microtomography (CµT) in biomedical research is well established, with most applications developed at synchrotron facilities. The possibility to non-invasively monitor morphological changes in biological samples, makes it an attractive technique in biomedicine. However, high absorbed doses and long examination times are a disadvantage that limits the possibilities of per...
