Shock waves and QPOs in 2D rotating accretion flows around black holes
2008
We examine numerically shock waves formed in 2D rotating accretion flows around a stellar‐mass and a supermassive black holes, while taking account of the cooling and heating of the gas and the radiation transport. As the results, we obtain general properties of the shock oscillations and the luminosity behaviors as QPOs independent of the black hole masses.
La transmissió lingüística intergeneracional a Castelló de la Plana i la Franja: La rellevància dels usos entre progenitors
2020
Fa 50 anys, a Conflicte lingüístic valencià, Rafael L. Ninyoles situava el trencament de la transmissió familiar del català com a resultat i manifestació externa de conflictes socials i de classes, especialment visibles enmig del procés de modernització econòmica i mobilitat social accelerada del País Valencià dels anys 60 del segle XX. En aquest article partim de dos estudis de cas quantitatius sobre la transmissió intergeneracional de les llengües a Castelló de la Plana i les comarques centrals de la Franja per a actualitzar el seu diagnòstic i matisar la visió d'aquest fenomen com a resultat de decisions dels progenitors imposades verticalment a la descendència. Hi proposem que els usos …
Radiative 2D Shocks, Super-Eddington Disks and Jets around Black Holes
2005
It is well known that rotating inviscid accretion flows with adequate injection parameters around black holes could form shock waves close to the black holes, after the flow passes through the outer sonic point and can be virtually stopped by the centrifugal force. Such shock waves in 2D accretion flows are examined by 2D radiation hydrodynamical calculations. We also examine super‐Eddington accretion disks with 15 ṀE around black holes, focusing on a small collimation degree of the jet and a large mass‐outflow rate observed in the X‐ray source SS 433.
In vitro differentiation of murine hematopoietic progenitor cells toward the myeloid lineage occurs in response to Staphylococcus aureus and yeast sp…
2013
We have studied the effect of inactivated microbial stimuli (Candida albicans, Candida glabrata, Saccharomyces boulardii, and Staphylococcus aureus) on the in vitro differentiation of lineage negative (Lin−) hematopoietic progenitor mouse cells. Purified Lin− progenitors were co-cultured for 7 days with the stimuli, and cell differentiation was determined by flow cytometry analysis. All the stimuli assayed caused differentiation toward the myeloid lineage. S. boulardii and particularly C. glabrata were the stimuli that induced in a minor extent differentiation of Lin− cells, as the major population of differentiated cells corresponded to monocytes, whereas C. albicans and S. aureus induced …
