Additional tests used in this case were valsalva, axial distraction, and axial compression. These tests are used primarily to differentiate radiculopathy from a central cord pressure (whether from space occupying lesion or disc herniation).
[12] up to two layers of CFRP jackets to strengthening of steel hollow sections subjected to axial compression were utilized.
In the simulations, because CNTs are usually bent inherently by Stone-Wales (SW) defects [15, 16], wavy CNTs were modeled by inserting multiple SW defects at different heights of a tube, resulting in the following findings under axial compression. C-shaped, point-asymmetric wavy CNTs with respect to their tube axial centers did not show any buckling point, and their axial compressive stresses asymptotically approached the axial compressive stress-strain curves of their pristine straight counterparts.
The specimens can be assigned into two groups, the first group (L60L, L75L, and L90L) with an axial compression ratio of 0.09 (the corresponding axial load is 200 kN) and the second group (L60S, L75S, and L90S) with an axial compression ratio of 0.24 (the corresponding axial load is 550 kN).
Furthermore, this column, without needing to consider the limit of axial compression force ratio, can reduce the column size to provide substantial benefits where floor space is at a premium such as in car parks and office blocks.
The experimental program comprised twelve (12) models of columns of reduced scale (h = 500 mm), under axial compression at the Laboratory of Civil Engineering of the Federal University of Para, in which nine (9) columns were strengthened with composite material of carbon fiber (CFRP).
In order to restore the load bearing capacity of an eccentrically loaded fracture bone, the tensile forces have to be absorbed by a tension band and the bone itself has to withstand axial compression. The pre-stressing of wire in tension results in the inter-fragmentary compression.
Whittle's patent application of January 1930 included a drawing of a gas turbine jet engine with two stages of axial compression preceding a single-stage centrifugal compressor.
Bone strength as formally measured in terms of anterior bending, axial compression, and axial torsion was also significantly greater in the teriparatide group, according to Dr.
When the angle is [theta] = [45.sup.0], we receive net shear and [[sigma].sub.x] = [[sigma].sub.u,c]/2, and when the angle is [theta] = 0, we receive axial compression and [[sigma].sub.x] = [[sigma].sub.u,c].
Patented recently is an absorbent tampon comprising: a chevron shaped mass of absorbent material which has been axially compressed into a generally cylindrical, self-sustaining form, wherein subsequent to the axial compression the generally cylindrical, self-sustaining form has a diameter of less that about 22 mm, the tampon having an absorbent capacity as measured by the syngyna test of between about 12 to about 15 grams, the tampon being fluid expanding, and the tampon having an expanded width upon fluid absorption of at least about 27 mm.
