Vents and/or exhaustion systems are istalled on the warehouse roofs aiming to equalize the silo in ternal pressure during the loading/unloaing processes, since providing the aeration air exit makes easier to re move gases originated from the stored grain ecosystem and dislocating the hot air acculated in the warehouse upper part through the convection currents.
With forced-air warming, mean temperatures were significantly elevated over the surgical site, which made one study's authors conclude, "Forced-air warming generates convection current activity in the vicinity of the surgical site.
