600,000,000 air cells in one pair of lungs, and 2,000 pores to a square inch of surface; so you see what quantities of air we must have, and what care we should take of our skin so all the little doors will open and shut right.
now school is dismissed, and I advise you to go and refresh your 600,000,000 air cells by a brisk run in the garden.
Ice has its grain as well as wood, and when a cake begins to rot or "comb," that is, assume the appearance of honeycomb, whatever may be its position, the air cells are at right angles with what was the water surface.
Elastic/VE foam had the largest stiffnesses and viscous fluid, air cell, and honeycomb were similar (p > 0.14).
A CT scan of the sinuses without contrast revealed hyperdense soft tissue opacifying the right sphenoid sinus extending to the right posterior ethmoidal air cells with osseous erosive changes; erosion of the right anterior wall of the sphenoid sinus, posterior right ethmoidal air cell septi; and mild erosion of the posterior medial walls of the maxillary sinus and medial wall of the orbit with minimal soft tissue extending to the orbital apex.
Mucocele is a rare inflammation that is believed to result from air cell obstruction.
Zygomatic air cell defect (ZACD) or pneumatized articular eminence has been described as an extended area of squamous cells in the root of the zygomatic arch and in the temporal part of the temporomandibular joint (TMJ) (1).
Air cell size was determined using a tripod micrometer.
Consequently, we set up a thermodynamic model, as shown in Figure 3, where 1, 2, and 3 represent the air cell, insulation layer, and outside air, respectively; [T.sub.1], [T.sub.2], [T.sub.3] are the temperatures of air cell, insulation layer, and outside air; [C.sub.1], [C.sub.2], [C.sub.3] are the specific heats correspondingly; Q is the input heat power; and [Q.sub.12], [Q.sub.23] are the thermal transmission quantities from air cell to insulating layer and insulating layer to outside air, respectively, [16-20].
The war media cell said in a statement that according to the Iraqi National Intelligence Service, and in coordination with the air cell information , the Sukhoi aircraft of the Iraqi Air Force carried out four strikes targeted the camp (The Cubs of Khelafa) and a laboratory for booby-trapping and shielding the vehicles in al-Qaim, in addition to the targeting of a store for improvised explosive devices inside a school and a site for improvised explosive devices and explosive materials in Akashat area.
