Cushions were then categorized into groups based on the materials of construction: viscous fluid (n = 5),
air cell (n = 7), elastic/viscoelastic (VE) foam (n = 6), and honeycomb (n = 3).
Bubbly
Air Cell: The
air cell has been ruptured and results in one or more separate air bubbles.
Imaging, which included CT brain, MRI brain, and CT sinuses, demonstrated hyperdense soft-tissue opacification of the right frontal, sphenoid sinuses, and ethmoidal
air cells with corresponding decreased T2 signal and osseous erosive changes involving medial orbital wall with soft tissue extending to the orbital apex.
Its cause is unknown and believed to occur as an
air cell obstruction, followed by mucosal edema, hemorrhage, inflammatory reaction, and bony expansion.
Zygomatic
air cell defect was studied using MRI and panoramic radiographs.
We have noted the grading system for
air cell pneumatization of temporal bone.
Figure 3d shows that the
air cell size increased with storage time [11].
Pneumatized
air cells present in the zygomatic process of the temporal bone, which appears similar to the mastoid
air cells and which does not extend further anteriorly than the zygomatico-temporal suture, entitled as zygomatic
air cell defect (ZACD).
I had my own project focused on analyzing under a microscope the
air cell size and distributions of whipped toppings and icings and then related the data to various process parameters searching for possible improvements.
Lindstrand USA in headquartered in South Boston, Virginia and is engaged in the manufacture of lighter-than-air vehicles and
air cell inflatable structures.
It also has
air cell massage seats, power adjustable leg supports for extra comfort, and a centre console which houses a cool box big enough to fit any refreshment.
