The influence of crystal form on the radial stress transmission characteristics of pharmaceutical materials
Autor: M P Summers, J. E. Carless, R.P. Enever
Publikováno v: Journal of Pharmacy and Pharmacology. 28:89-99
Various crystal forms of sulphathiazole, barbitone and aspirin were compressed in a single-punch tablet machine instrumented to monitor axially applied and radially transmitted forces, and upper punch movement. The changes in radial stress during the

The use of strain gauges for radial stress measurement during tableting
Autor: P D Huckle, M P Summers
Publikováno v: The Journal of pharmacy and pharmacology. 37(10)
The influence of size, configuration and positioning of die wall strain gauges on the measurement of radially transmitted stress developed during tableting was investigated. Calibration of strain gauges attached to a cutaway die wall was achieved by

High resolution electron microscopy study of sulphathiazole crystals
Autor: M P Summers, Z H Luklinska, O O Solanke
Publikováno v: The Journal of pharmacy and pharmacology. 41(8)
A high resolution electron microscopy study was undertaken on samples of sulphathiazole obtained by recrystallization at 0°C, 30°C and 70°C. Low magnification electron microscopy study of the crystals showed featureless morphology yet the resolved

Thermal behaviour and dissolution properties of phenylbutazone polymorphs
Autor: J. E. Carless, M P Summers, M D Tuladhar
Publikováno v: The Journal of pharmacy and pharmacology. 35(4)
Five different polymorphic forms of phenylbutazone were prepared and characterized by differential scanning calorimetry (D.S.C.). Rapid heating rates produced single endothermic peaks due to melting but slower heating rates resulted in interconversio
