Great Axis

In practice, vapor release will not be spherical, as is assumed in the method. A release from a cylinder burst may produce overpressures along the vessel s axis, which are 50% lower than pressures along a line normal to its axis. If a vessel ruptures from ductile, rather than brittle, fracture, a highly directional shock wave is produced. Overpressure in the other direction may be one-fourth as great. The influences of release direction are not noticeable at great distances. Uncertainties for a BLEVE ate even higher because of the fact that its overpressure is limited by initial peak-shock overpressure is not taken into account. 

The solid plates that resulted from the cooling process at the surface of the eanli were able to float on the remaining molten inner portion of the earth. Because of the rotational motion of the earth about its own axis and the earth s motion in the solar system, inertial and gravitational forces have produced great interactive forces between the plates. It is speculated that these interactive forces have led to plate contact and situations where one plate has slid over another. The great forces created by plate tectonics are likely responsible for the forces that have resulted in the folding and faulting of the earth s crust [30j. 

The two forms differ by the way they pack, a direct result being the different tilt angle of their molecular axis (24" and 30" for the low-temperature and high-temperature form, respectively). Another important difference is the fact that the inversion center of the molecule coincides with a center of symmetry of the unit cell in the HT form, whereas it does not in the LT form 84J. Direct consequences of this feature have not yet been identified. It will be of course of great interest to know what would be its influence on charge transport properties. 

The values for Cl2 are bx = 6.60, b2 = 3.62, both x 10 24 cm3. When these values are substituted in Eq. 43 together with R = 1.99 X 10 8 cm, one obtains ax == 1.79 and a2 = 2.36, both X 10 24 cm3. Thus, although the polarizability of the chlorine molecule is almost twice as great parallel than perpendicular to the axis, the atom is nearly isotropic with slightly greater polarizability perpendicular to the axis. 

A common use is with a plastic hub or boss accepting either a plastic or metal insert. The press fit operation tends to expand the hub creating a tensile or hoop stress. If the interference is too great, a very high strain and stress will develop. The plastic product will (1) fail immediately by developing a crack parallel to the axis of the hub to relieve the stress, a typical hoop stress failure, (2) survive assembly but fail prematurely when the product is in use for a variety of... 

A great deal of excitement has been generated by the assertion that some intercalation compounds of graphite possess a conductivity greater than that of copper (VIO, F13, Til). Much of this work was based upon earlier researches by Ubbelohde, who found that the a-axis conductivity of the semi-metal graphite increases, and develops a me-... 

Thus, if the vertical axis representing the double-quantum frequencies is defined by v, and the horizontal axis representing the chemical shifts of the two carbons A and X is defined by V2, then both pairs of C satellites of nuclei A and X will lie on the same row (at + Vx), equidistant from the diagonal. This greatly facilitates identification. The advantage is that no overlap can occur, even when fir.c values are identical, since each pair of coupled C nuclei appear on different horizontal rows.
