Bulk viscosity

preading area through a 1.3 cm deep matrix was reduced with increased moisture content, densely packed matrixes, and higher viscosity oils. Initial contact angle (CA) measurements for all oils was typically lower on clay matrixes due to its sheet-like structure and high absorption capabilities. Individual droplet penetration took longer at lower MC in direct contradiction to bulk kinetics studies, suggesting different spreading behavior across the surface border.

We discuss a cosmology in which cold dark-matter begins to decay into relativistic particles at a recent epoch (z < 1). We show that the large entropy production and associated bulk viscosity from such decays leads to a recently accelerating cosmology consistent with observations. We investigate the effects of decaying cold dark matter in a Λ = 0, flat, initially matter dominated cosmology. We show that this model satisfies the cosmological constraint from Type Ia supernovae at high redshift. Possible additional observational tests of this new cosmological paradigm are suggested.

We find that this model can only fit the observational constraints if there is a cosmological constant and the presence of non-decaying cold dark matter in addition to decaying cold dark matter. Thus, although this remains a viable model, it is only able to partially explain the observed cosmic acceleration.

Drug Administration be very precise. (Standardized medicinal teaspoons and tablespoons are available.) Eye drops and nose drops (A) are designed for application to the mucosal surfaces of the eye (conjunctival sac) and nasal cavity, respectively. In order to prolong contact time, nasal drops are formulated as solutions of increased viscosity. Solid dosage forms include tablets, coated tablets, and capsules (B). Tablets have a disk-like shape, produced by mechanical compression of active substance, filler (e.g., lactose, calcium sulfate), binder, and auxiliary material (excipients).
