A Comparison of in vivo Cellular Responses to CS-137 Gamma Rays and 320-KV X Rays
Dose-Response, 2013 Research reported here relates to comparing the relative effectiveness of 320-kV X rays compared to Cs-137 gamma rays for two in vivo endpoints in C.B-17 mice after whole-body exposure: (1) cytotoxicity to bone marrow cells and splenocytes evaluated at ...

X-ray Polarimetry of X-ray Pulsars
GalaxiesRadiation from X-ray pulsars (XRPs) was expected to be strongly linearly polarized owing to a large difference in their ordinary and extraordinary mode opacities. The launch of IXPE allowed us to check this prediction. IXPE observed a dozen X-ray pulsars, discovering pulse-phase dependent variation of the polarization degree (PD) and polarization angle

Modeling Gamma-Ray Emission From the High-Mass X-Ray Binary LS 5039 [PDF]
Journal of Astronomy and Space Sciences, 2012 A few high-mass X-ray binaries–consisting of an OB star plus compact companion– have been observed by Fermi and ground-based Cerenkov telescopes like High Energy Stereoscopic System (HESS) to be sources of very high energy (VHE; up to 30 TeV) γ-rays ...

On the Intensity of Total Scattering of X-Rays
, 1929 We shall here investigate theoretically the intensity of total scattering of X-rays by atoms distributed at random, e. g. , the scattering by the atoms of a monatomic gas.

X-RAY MONITORING OF ULTRALUMINOUS X-RAY SOURCES [PDF]
The Astrophysical Journal, 2009 X-ray monitoring observations were performed with the Swift observatory of the ultraluminous X-ray sources Holmberg IX X-1, NGC 5408 X-1, and NGC 4395 X-2 and also of the nuclear X-ray source in NGC 4395. Holmberg IX X-1 remains in the hard X-ray spectral state as its flux varies by a factor of 7 up to an (isotropic) luminosity of 2.8E40 erg/s.

Densitometer system for liquid hydrogen has high accuracy, fast response [PDF]
, 1966 Developmental densitometer system for cryogenic liquids uses two balanced ionization chambers containing xenon gas, with X rays as the radiation source. The X rays are heavily filtered with a lead shield to make the energy spectrum much less dependent on

Analisa Difraksi Sinar-X pada Baja Tahan Karat Austentitik dan Feritik (Uji Laboratorium)
Journal of Dentistry Indonesia, 2015 X- rays with wavelength in the range 0,5 to 2,5 Å, have a very short wavelength compare to the visible light wavelength in order of 6000 Å. Therefore, x-rays can be used for determination of the finest structure of materials by using the x-rays ...

A note on X-rays of permutations and a problem of Brualdi and Fritscher [PDF]
arXiv, 2017 The subject of this note is a challenging conjecture about X-rays of permutations which is a special case of a conjecture regarding Skolem sequences. In relation to this, Brualdi and Fritscher [Linear Algebra and its Applications, 2014] posed the following problem: Determine a bijection between extremal Skolem sets and binary Hankel X-rays of ...
