In this work, we propose an economical model to address some open cosmological problems such as the absence of initial singularity, early acceleration Universe and generation matter-antimatter asymmetry. The is based on a scenario in which consists non-linear electrodynamics fields. It found that has equation state $p=\frac{1}{3} \rho - \frac{4}{3} \beta \rho^{1+\alpha}$ shows undergoes epoch r...

Abstract The results reported herein were motivated by the potential application of combined optically stimulated (OSL) and thermoluminescence (TL) measurements for separation between beta neutron dose components in mixed neutron-beta radiation fields. advantages OSL/TL are two-fold: (i) OSL TL readout can be carried out on same sample (ii) greater efficiency to high ionization density (HID) du...

Most tokamak devices including ITER exploit the D-T reaction due to its high reactivity, but wall loading caused by associated 14MeV neutrons will limit further development of fusion performance at beta. To explore p-11B cycle, a system code is extended incorporate relativistic bremsstrahlung since temperature electrons approaching rest energy electron. By choosing an optimum mix and ion temper...

Since the first case was detected on March 3, 2020, incidence of COVID-19 has exponentially increased in Jakarta. Some theories claimed that virus activities were affected by climate variability. The aim this study is to search and predict correlation between daily incidences with variability A cross sectional made, sampling total cases Jakarta from 3 July 2020. Climate consisted mean temperatu...

We report on attempts to construct and simulate low intensity sources of Cerenkov radiation with accurately known spectral intensity. These sources will be used to calibrate photomulti-pliers for the Sudbury Neutrino Observatory. We have used ^Sr as a radioactive beta source located at the center of a sphere of ultraviolet transparent acrylic. The production of Cerenkov radiation by stopping el...

OBJECTIVES The study sought to determine the incidence and predictors of late total occlusion (LTO, >30 days) in-patients with in-stent restenosis who were treated with intracoronary radiation. BACKGROUND Intracoronary radiation both with beta and gamma emitters has been shown to reduce recurrent in-stent restenosis. METHODS We reviewed the records of 473 patients who presented with in-sten...
