ABSTRACT We examine the gas content of field dwarf galaxies in a high-resolution cosmological simulation. In agreement with previous work, we find that inhabiting dark matter haloes mass below critical value, M200 ≲ Mcrit ≈ 5 × 109 M⊙, are quiescent at present day. The these is thus insensitive to feedback from evolving stars. Almost half systems today have masses much smaller than expected for...

The gas content of the complete compilation Local Group dwarf galaxies (119 within 2 Mpc) is presented using HI survey data. Within virial radius Milky Way (224 kpc here), 53 55 are devoid to limits M$_{\rm HI}<10^4$ M$_\odot$. M31 (266 kpc), 27 30 (with typically $<10^5$ M$_\odot$). Beyond radii and M31, majority have detected masses higher than limits. When relationship between distance inves...

In order to study whether there is any correlation between nuclear activities, gas content, and the environment where galaxies reside, we have obtained optical and millimetric spectra for a well-defined sample of intermediate Hubble type spirals in dense environments and in the field. We found that these spirals in dense environments have on average: less molecular gas per blue luminosity, high...

this study was carried out to investigate the effects of treated protein supplements with tannin extracted from pistachio by-product (p-pb) on in vitro gas production using fistulated sheep. one portion of p-pb was mixed with four portions of water for 48 h. the extracted product was sprayed on soybean meal (sbm) or canola meal (cm) with an equal ratio (1:1 v/w) and dried in the shade. the expe...

Spinal cord injury (SCI) is one of the most severe traumatic injuries that results in dysfunction of limbs and trunk below the damaged section. Recent studies have shown that gastrodin (GAS) could improve the recovery of SCI. In the current study, we aimed to examine the possible mechanism underlying the effect of GAS on recovery of SCI in rats. In rats with SCI, GAS improved locomotor function...
