Abstract Dust clouds are ubiquitous in the atmospheres of hot Jupiters and affect their observable properties. The alignment dust grains resulting polarization provide a promising way to study magnetic fields exoplanets. Moreover, grain size distribution plays an important role physical chemical processes atmospheres, which rather uncertain. In this paper, we first by radiative torques (RATs). ...

We present 870 $\mu$m ALMA polarization observations of thermal dust emission from the iconic, edge-on debris disk $\beta$ Pic. While spatially resolved map does not exhibit detectable polarized emission, we detect at $\sim$3$\sigma$ level when averaging across entire disk. The corresponding fraction is $P_\textrm{frac}$ = $0.51 \pm 0.19$%. position angle $\chi$ aligned with minor axis disk, as...

this study aimed to explore and validate a new juvenile osteopenic (jo) rat model then examine the efficacy of moghat (glossostemon bruguieri) as an alternative reversal therapy for jo. phytochemical screening analysis showed that moghat contains 5.8% alkaloids, 1.5% flavonoids and 13.2% total phenols. juvenile osteopenia was induced in 15 days old sprague- dawley female rats by feeding them fr...

Objective: The global pandemic of Coronavirus Disease 2019 (COVID-19) is still spreading. Because this, it urgently necessary to develop quick, easy, and accurate assays identify severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. For the purpose diagnosing COVID-19 cases, quick SARS-CoV-2 antigen detection test’s performance attributes should be assessed contrasted with gol...

by late 18th or early 19th century, albino rats became the most commonly used experimental animals in numerous biomedical researches, as they have been recognized as the preeminent model mammalian system. but, the precise correlation between age of laboratory rats and human is still a subject of debate. a number of studies have tried to detect these correlations in various ways. but, have not s...

"Rat trading"—"front-running" in the U.S.—is a typical criminal behaviour securities market. To better reduce emergence of "rat trading" behaviour, this paper expounds on essence through theoretical analysis. It highlights defects current management. Because existing flaws, puts forward solutions for reference relevant personnel.

We study the physical processes inducing alignment of grain axis maximum inertia moment with angular momentum (${\bf J}$, i.e., internal alignment) and ${\bf J}$ magnetic field (i.e., external very large grains (VLGs, radius $a>10\mu$m) using framework based on radiative torques (RATs) mechanical (METs). derive analytical formulae for critical sizes alignment, assuming that are aligned at both ...
