We present a new technique called quantile analysis to classify spectral properties of X-ray sources with limited statistics. The quantile analysis is superior to the conventional approaches such as Xray hardness ratio or X-ray color analysis to study relatively faint sources or to investigate a certain phase or state of a source in detail, where poor statistics does not allow spectral fitting ...

We describe a model for the X-ray emission produced during collisions and mergers of disk galaxies. To study this process, we employ simulations that incorporate cosmologically motivated disk-galaxy models and include the effects of radiative cooling, star formation, stellar feedback, and accreting supermassive black holes. We find that during a merger, the colliding gas in the disks is shockhe...

The geochemical and geological characterization of clay is an important approach to determining the quality productivity for industrial use. This paper aimed at providing detailed geochemistry, distribution, utilization from eastern part Hawal massif. field study revealed that occurs in Bagira, Vimtim, Didif, Bulamary, Ngavahi, Dou-Gada, Madanya, TudunWada, Moda, Kwabapale. clays are residual d...

BACKGROUND Bisphosphonates (BPs) are used extensively for managing the osteoporosis. There are some controversies on atypical fractures of femur that associated with increase in cortical thickness (CT) and BPs' use. In this study, the effects of alendronate consumption were studied on femoral CT as a predictor for atypical fracture. METHODS Forty nine post-menopausal women aged 50-70 years wi...

Ion implantation is a surface modification technology to produce new material on the surface by impingement of high energy ions from the ion accelerator. In this work, AISI 304 stainless steels were coated with 90 nm Ni film by electron beam deposition and implanted by a flow of 5×1017 N cm−2 at 400 K temperature with different implantation energies of 10, 20, 30 and 40 keV. The prepared sample...

Abstract Aim To ensure that requests for plain AXR surgical conditions the patients admitted in SAU are performed appropriately as advised by Royal College of Radiologists guidelines. We intend to reduce radiation dose and early access more appropriate investigations. RCR iRefer guidelines Methods Patients with abdominal pain month October 2020 were taken. Total number audited 50. 22 had wherea...

We discuss the use of one-nucleon removal reactions of loosely bound nuclei at intermediate energies as an indirect method in nuclear astrophysics. The breakup reactions are proved to be good spectroscopic tools and can be used to study a large number of loosely bound protonor neutron-rich nuclei over a wide range of beam energies. As peripheral processes, they can be used to extract asymptotic...

We present a wide-field imaging study of the colors of bright galaxies (<M þ 2) in a sample of 12 X-ray–selected clusters and groups of galaxies at z 0:3. The systems cover one of the largest ranges in X-ray luminosity (LX 10 10 ergs s ), and hence mass, of any sample studied at this redshift. We find that the ‘‘red’’ galaxies form a tight color-magnitude relation (CMR) and that neither the slo...

(comparable only with hydrated RuO 2 ) was measured for Ti 3 C 2 T x in aqueous electrolytes. [ 11,14 ] Our previous studies revealed that spontaneous intercalation of some cations takes place when MXene samples are exposed to aqueous electrolytes. [ 6 ] In situ X-ray diffraction showed that variations of the distance between the Ti 3 C 2 T x layers (which is proportional to the c lattice param...
