During the core collapse of massive stars that do not undergo a canonical energetic explosion, some hydrogen envelope red supergiant (RSG) progenitor may infall onto newborn black hole (BH). Within Athena++ framework, we perform three-dimensional, hydrodynamical simulations idealized models convection and in order to assess whether convective can give rise rotationally-supported material, even ...

BACKGROUND Primary visceral malignant fibrous histiocytoma (MFH) is a rare disease, and few cases have been reported in the English literature. However, retained foreign bodies in the abdomen after surgical procedures are important causes of intra-abdominal infections. For legal and ethical reasons, there are few publications in the literature. In this article, we describe for the first time a ...

Five steam-flaked sorghum grain (SFSG) samples with bulk densities of 476, 412, 347, 309 and 283 g/liter made by adjusting tension between mill rollers and three reconstituted sorghum grain (RSG) samples with reconstitution times of 10, 20 and 30 d and a control sample were analyzed for gas production kinetics (rumen liquor fermentation) and enzymatic glucose release (amyloglucosidase). Protein...

Reversible logic is one of the flourishing importance to many futuristic technologies. A reversible circuit maps each input vector into a unique output vector. There should not be any information loss in the circuit, because it is proved that each irreversible bit operation dissipate kTln2 amount of energy, but there are so many fields such as cryptography, optical computing, DNA computing etc....

We present H-band spectra of the candidate counterparts of five ULXs (two in NGC 925, two in NGC 4136, and Holmberg II X-1) obtained with Keck/MOSFIRE. The candidate counterparts of two ULXs (J022721+333500 in NGC 925 and J120922+295559 in NGC 4136) have spectra consistent with (M-type) red supergiants (RSGs). We obtained two epochs of spectroscopy of the candidate counterpart to J022721+333500...

PURPOSE In this study, we tested the hypothesis that rosiglitazone (RSG) with insulin is able to quench oxidative stress initiated by high glucose through prevention of NAD(P)H oxidase activation. METHODS AND MATERIALS Male albino Wistar rats were randomly divided into an untreated control group (C), a diabetic group (D) that was treated with a single intraperitoneal injection of streptozotoc...

We present 3000–10000 Å HST/STIS long-slit spectroscopy of the bright super star cluster A (SSC-A) in the dwarf starburst galaxy NGC 1569. The 0.05 HST angular resolution allows, for the first time, to probe for spatial variations in the stellar population of a ∼ 10M⊙ SSC. Integrated ground-based spectra of SSC-A have previously revealed young Wolf-Rayet (WR) signatures that coexist with featur...

Success is the result of planning, hard work, determination, foresight, and a little bit of luck. Unfortunately, nobody has thought to pave the road to success. Although failure can be discouraging and time-consuming, it presents incredible learning opportunities-the biggest difference between those who succeed and those who abandon their projects lies in their response to adversity. This artic...
