In the set of 236 GRB afterglows observed by Swift between January 2005 and March 2007, we identify 30 X-ray light-curves whose power-law fall-off exhibit a steepening (”break”) at 0.1–10 day after trigger, to a decay steeper than t−1.5. For most of these afterglows, the X-ray spectral slope and the decay indices before and after the break can be accommodated by the standard jet model although ...
We present a multi-wavelength study of GRB 081008, at redshift 1.967, by Swift, ROTSE-III, and Gamma-Ray Burst Optical/NearInfrared Detector. Compared to other Swift GRBs, GRB 081008 has a typical gamma-ray isotropic equivalent energy output (∼1053 erg) during the prompt phase, and displayed two temporally separated clusters of pulses. The early X-ray emission seen by the Swift X-Ray Telescope ...
Dynamic modeling and simulation of fixed bed adsorption process was carried out by explaining the behavior of breakthrough curve parameter. Adsorption of sulfur compound, present in road fuel, has posed a great challenge. A model of fixed bed adsorption of benzothiophene from fuel was formulated with non-ideal plug flow behavior and considered velocity variation along a column. The model was so...
Rarely, do we think of cancer as “bacterial”, such that we are often told that “cancer is NOT contagious” Persistent bacterial infections cause persistent irritation of the host’s defense systems, which when ineffective in eradication of the infection, result in a multitude of self-destructive damages. This in some cases occurs to such severity that the resu...
Background: Despite efforts to develop a COVID-19 vaccine, it has failed provide long-term immunity and protection against the newly worrying SARS-CoV-2 coronavirus strains. Understanding cytokines, which are key in generating unique immune responses from pathogenic organisms, is important for creating vaccines.
 Objective: In order better understand cytokines how current vaccinations can ...
