TL;DR: The ability to convert the load at which a tablet fails in tension under diametrical compression, into a tensile strength, has been reported for tablets produced using flat-faced punches but there does not appear to be a stress analysis for specimens of this shape, so an empirical solution to the problem was sought.

TL;DR: If comparisons are to be made between processing treatments or mixtures which change the initial packing of the powder, the Heckel equation would appear to offer the most valid approach.

TL;DR: Enteric beads have been produced using a purely aqueous system and drug release studies show that the relatively insoluble compound is well protected in an acidic environment but rapid release occurs when the pH is raised.

TL;DR: In this article, the contact angles of mixtures of powders consisting of spherical particles have been measured using the h-ϵ technique and penetration studies, and the results show that the hydrophobic component dominates the contact angle of the mixture, although this dominance is reduced as the particle size of a mixture is reduced.

TL;DR: During a series of experiments on the gastric emptying of capsules, certain subjects were exposed to stress in the form of high noise levels and in the non‐fasting condition, these subjects showed a significantly faster gastric emptied than those who were not exposed to the stress.
