Density, s

Relative density is usually determined at ambient temperature with speciahzed hydrometers. In the United States these hydrometers commonly are graduated in an arbitraiy scale termed degrees API. This scale relates inversely to relative density s (at 60°F) as follows (see also the abscissa scale of Fig. 27-3) ... 

In this case the volume density S(q) tends to infinity as h, when h(q) approaches zero. Correspondingly, the expression for the field is... 

Recently [7] we constructed an example showing that interfacial flexibility can cause instability of the uniform state. Two elastic capacitors, C and C2, were connected in parallel. The total charge was fixed, but it was allowed to redistribute between C and C2. It was shown that if the interface was absolutely soft , i.e., contraction of the two gaps was not coupled, the uniform distribution became unstable at precisely the point where the dimensionless charge density s reached the critical value, = (2/3). In other words, the uniform distribution became unstable at the point where, under a control,...

Fig. 4.10. Portion of the red spectrum of the H II galaxy Tololo 0633-415 with a redshift of 0.016, showing diagnostic features for helium (Ha and X 6678), electron density ([S n]) and ionization ([S hi]). The features marked cosmic ray are due to impacts of charged particles on the CCD detector. After Pagel et al. (1992).

An analytical theory of the outer-sphere PRE for slowly rotating systems with an arbitrary electron spin quantum number S, appropriate at the limit of low field, has been proposed by Kruk et al. (144). The theory deals with the case of axial as well as rhombic static ZFS. In analogy to the inner sphere case (95), the PRE for the low field limit could be expressed in terms of the electron spin spectral densities s ... 

Table III shows the result of SANS analysis on fully polymerized PB/PS IPN s, seml-IPN s, and chemical blends by Fernandez et al. [ n.] The specific interfacial surface area was shown to increase with Increasing crosslink density, S decreasing in the order full-IPN s, semi-I IPN s, seml-II IPN s afid chemical blends, as expected from many earlier studies. Its value ranges from 20 to 200 m /gm, in the range of true colloids. This result is particularly important because interfacial surface area is closely related to toughness and impact strength.

The surface coverage of empty sites [S] is the fraction of total sites (density [S ,]) not occupied by adsorbed molecules. Since the surface is assumed to saturate when 9 = 1, then 0s = 1 - 0A, or...

To find a principle which so narrows down the statistics (e.g., to a subclass of probability densities S ) that 9 relations in addition to the 5 transport equations will hold between our macroscopic quantities, so that the initial value problem for (p, ua, E), with the basic boundary conditions, will become determinate. In actuality, this will amount to finding a principle from which the various phenomenological relations of two paragraphs back are (approximate) deductions. 

Finally, it is seen that we have here a theory, not of the true but of classes of probability densities S ...

We study the system for different densities S of lattice sites which are accessible (active) to the reacting particles. For the case of 0 < S < 1 we obtain a lattice in which the active sites form smaller or larger islands. These islands are separated on the lattice in such a way that the particles occupying one island cannot interact with particles sitting on another island. In contrast to the computer simulations performed for such a system [25], we do not remove here finite clusters from the surface.

In our model the moduli of the nematic and smectic order parameters play similar roles, so we will deal with both. Since we consider a situation beyond the phase transition regime, the equilibrium value of the order parameter is non-zero (S s for both nematic and smectic) and only its variations s(n,s can enter the energy density (S = S(q s) + s ) ...
