We consider the nonlocal Hénon-Gelfand–Liouville problem $$\begin{aligned} (-\Delta )^s u = |x|^a e^u\quad \mathrm {in}\quad \mathbb {R}^n, \end{aligned}$$ for every $$s\in (0,1)$$ , $$a>0$$ and $$n>2s$$ . prove a monotonicity formula solutions of above equation using rescaling arguments. apply this together with blow-down analysis arguments technical integral estimates to establish non-existen...

Background: Human activities such as mining enhance the radioactivity levels above normal background which can lead to an incremental increase in the radiation risk to the population. Materials and Methods: 20 tailing enriched soil samples collected around Maiganga coal mine, Gombe, Northeast Nigeria were assessed for their 226Ra, 232Th and 40K contents using HPGe gamma-ray detector. Results: T...

Quality assurance (QA) for intensity- and volumetric-modulated radiotherapy (IMRT and VMAT) has evolved substantially. In recent years, various commercial 2D and 3D ionization chamber or diode detector arrays have become available, allowing for absolute verification with near real time results, allowing for streamlined QA. However, detector arrays are limited by their resolution, giving rise to...

UNLABELLED An association between fatty liver and carotid atherosclerosis has been established; however, it is not clear whether this relationship is a consequence of shared conventional risk factors or whether it is determined by specific circulating factors originating from liver or adipose tissue. To identify the factors possibly linking fatty liver and atherosclerosis, we assessed, in 1,012...

Background: The study of rheological properties of blood has special interest since it is a circulating fluid exposed to shear rates during its life time. This work aims to investigate the influence of whole body gamma irradiation on the rheological properties of rat’s blood. The applied shear rate was from 12 to 375 s-1. Low shear viscosity (up to 100 s-1) depends mainly on the erythroc...

We show that the jet structure of gamma-ray bursts(GRBs) can be investigated with the tail emission of the prompt GRB. The tail emission that we consider is identified as a steep decay component of the early X-ray afterglow observed by the X-Ray Telescope on board Swift. Using a Monte Carlo method, we derive for the first time the distribution of the decay index of the GRB tail emission for var...

many biological factors affect radiosensitivity. in this study, radiosensitivity among the different blood groups was investigated. peripheral blood sample of 95 healthy people were divided into two parts. one part was irradiated with 2 gy co-60 gamma rays and the second one was considered as control. then all the samples were studied by cytokinesis-blocked micronucleus assay (cbmn assay). our ...
