Urban Geometry: The Effect of Height Diversity and Buildings Configuration on Thermal Performance and Cooling Load at Urban Scale. A Case Study in Dubai / UAE by SHAREEF, SUNDUS LUAY

“…However, this arrangement reduces the wind speed due to the obstruction created by the buildings mass and decreases the air velocity in the canyons. On the other hand, this type of configuration improves the distribution of the air around the buildings block and consequently enhances the outdoor thermal comfort around most of the buildings within the urban block. …”

IL-1 stimulates ceramide accumulation without inducing apoptosis in intestinal epithelial cells by Homaidan, Fadia R.

“…Results: IL-1 increased ceramide accumulation in a time-dependent and concentration-dependent manner with a peak response at 4 h, with [IL-1] = 30 ng/ml. Neither IL-1 nor ceramide induced apoptosis in IEC, but they increased bcl-2 levels and decreased bax and p21 levels without affecting bcl-x and p53 levels. …”
