Longitudinal vertical plane

In the surface of a half space that is isotropic, the Rayleigh wave velocity is the same in all directions. If the surface is imagined to be in a horizontal plane, then the Rayleigh wave is composed of a shear wave component polarized in a vertical plane (SV) and a longitudinal wave component. Shear waves polarized horizontally (SH) can also exist, but they do not couple to the Rayleigh wave at all (nor, in the case of fluid loading, would they couple into waves in the fluid). 

Properties.—Orthorhombic crystals prismatic, often acutely terminated vertical planes striated or deeply furrowed longitudinally crystals often curved, bent in knee-shaped forms or twisted. Commonly occurs in confused aggregates of acicular crystals, also in radiating groups massive, coarse or fine, columnar. H. = 2. G. = 4-52-4-62. Lustre metallic, highly splendent. Colour and streak lead-gray. 

The two hippocampal formations in the brain resemble an inverted V as viewed from above (see Fig. 1 A). Each hippocampus is a U-shaped structure with the top opening of the letter U facing forward and medially (see Fig. IB). If the hippocampus on the right side of the brain is used, the blade should be placed 45° across the longitudinal fissure at a point one-third from the posterior end (see Fig. lA) and rotated 15° back from the vertical plane (see Fig. IB).

The hippocampus, represented by the dashed lines, is covered by the neocortex and is not visible from above. The two solid lines across the brain indicate the positions where the first and the second cuts are made Note that the blade should be rotated 15 back from the vertical plane as shown in B (B) Lateral view of the brain showing the right hippocampus, The straight dashed line is perpendicular to the surface of the neocortex. The solid lines across the brain are 15° offset from the dashed line and indicate where the first and second cuts are made. Five to six slices can be obtained from the stippled area that is perpendicular to the longitudinal axis of hippocampus, (C) View of the second cut surface. Make the third cut perpendicular to the surface of the second cut along the line shown in the figure-...

Wood Specimens. Southern pine sapwood blocks, 2.4 x 2.4 x 0.6 cm (longitudinal x radial x tangential), were prepared from a single freshly cut log. All specimens were cut and planed to provide a smooth vertical-grain surface and ovendried for 20 hrs at 105°C. The 70 specimens were randomized for use in different portions of the study. 

Figure 2.1 Pictorial representations of elastic waves in solids. Motions of groups of atoms ate depicted in these cross-sectional views of plane elastic waves propagating to the right. Vertical and horizontal displacements are exaggerated for clarity. Typical wave speeds, Vp, are shown below each sketch, (a) Bulk longitudinal (compressional) wave in unbounded solid, (b) Bulk transverse (shear) wave in unbounded solid, (c) Surface acoustic wave (SAW) in semi-infinite solid, where wave motion extends below the surface to a depth of about one wavelength, (d) Waves in thin solid plates.

Transverse dispersivity has been less studied, but it is smaller than the longitudinal dispersivity. Measurements from tracer studies indicate that the transverse horizontal dispersivity is about 10% of the longitudinal dispersivity in the bedding plane, and the transverse vertical dispersivity is about 1% (Gelhar, 1997). Klenk and Grathwohl (2002) found that the transverse vertical dispersivity was determined mostly by diffusion. 

The SAE (Society of Automotive Engineers) and JEVS (Japan Electric Vehicle Society) has established a standard size for EV battery modules at L388(2) mm X W116(2) x HI75(2) ((2) is the error allowed in the dimension), with a top-terminal configuration on the vertical longitudinal plane of symmetry [14]. In VRLA, this size provides a 12-V capacity of about 60 Ah in Ni-MH, this provides... 

Figure 4.12 Schematic of a conventional insertion device. The magnetic field is parallel to the vertical direction (Oz). It is a sinusoidal function of the longitudinal coordinates. The trajectory of an electron submitted to this field is a sinusoid in the horizontal plane (0s,0 c). From Ellaume (1989b) with permission of the author and Gordon and Breach Science Publishers SA.

The longitudinal Brillouin spectrum appears when both the incident and scattered light are polarized vertically with respect to the scattering plane (/vv) The transverse Brillouin spectrum results when the incident polarization is perpendicular to the scattered polarization (Ihv =1vh).
