A cubic silsesquioxane. A silsesquioxane is an organosilicon compound with the chemical formula [RSiO 3/2] n (R = H, alkyl, aryl, alkenyl or alkoxyl.). [1] Silsesquioxanes are colorless solids that adopt cage-like or polymeric structures with Si-O-Si linkages and tetrahedral Si vertices.
alternative meanings of ambiguous morpheme, e.g. 2/3 for a morpheme that may be either 2nd or 3rd person, or DAT/GEN for a suffix used for both dative and genitive. [ 27 ] [ 6 ] [optional in place of period] a morpheme indicated by or affected by mutation, as in Väter-n (father\ PL-DAT.PL ) "to (our) fathers" (singular form Vater )
Continuous charge distribution. The volume charge density ρ is the amount of charge per unit volume (cube), surface charge density σ is amount per unit surface area (circle) with outward unit normal nĚ‚, d is the dipole moment between two point charges, the volume density of these is the polarization density P.
Visulization of flux through differential area and solid angle. As always ^ is the unit normal to the incident surface A, = ^, and ^ is a unit vector in the direction of incident flux on the area element, θ is the angle between them.
GQ(2,2), the Doily. In geometry, a generalized quadrangle is an incidence structure whose main feature is the lack of any triangles (yet containing many quadrangles). A generalized quadrangle is by definition a polar space of rank two. They are the generalized n-gons with n = 4 and near 2n-gons with n = 2.
1. Center line, the central axis of a feature. 2. Class, for example, "paint per spec XYZ revision C type 1 class 2" may be abbreviated as "paint per spec XYZ REV C TY 1 CL 2" or even in some cases "paint per spec XYZ-C-1-2". (The latter practice is not uncommon but is cryptic for workers with minimal training and experience. The first two ...
Upon polarization negative and positive bound charges will be displaced. Let d 1 and d 2 be the distances of the bound charges and +, respectively, from the plane formed by the element of area dA after the polarization. And let dV 1 and dV 2 be the volumes enclosed below and above the area dA. Above: an elementary volume dV = dV 1 + dV 2 ...
