Regardless of the ever-present value of drugs in Roman literature, philosophy, and social background, the language of Latin scientific texts has no longer been safely studied. This publication provides the 1st systematic account of part of this huge, wealthy box. focusing on texts of "high" drugs written in knowledgeable, even literary, Latin Langslow deals a close linguistic profile of the scientific terminology of Celsus and Scribonius Largus (first century advert) and Theodorus Priscianus and Cassius Felix (fifth century AD), with widespread comparisons with their respective near-contemporaries.

The matrix surface becomes porous, giving it a spongy texture. The ionic strengths which caused disintegration varied according to the salt used. 0 of sodium chloride was required to effect disintegration. Since the disintegration of the tablets can be explained by the salts decreasing the cloud point then their efffect on disintegration should also follow the lyotropic series. On this basis sodium salts appear anomalous since they should produce lower disintegration times than potassium salts.
The speed of the machine was adjusted to one tablet s−1. 8mm perforations for the final milling. MATRIX FORMULATIONS [CH. 4 45 (4) Grinding and separation of the particle size ranges in a Russell vibratory machine (Russell Finex, London and New York). (5) Lubrication for 3 min. (6) Final compression on the same instrumented tablet machine to obtain a 400 mg tablet. TESTS PERFORMED Powder test Powder flow rate was determined using a glass funnel. Engelsmann AG) tapping volume meter [14–16]. Physics of compression In sampling ten tablets, the following parameters were studied: the lubrication index (R), the ejection force (Fc), the residual force (Fr) and the cohesion index (CI=ratio of the pressure applied to the upper punch and the tensile strength) proposed by Guyot .
