Glass micro-fibre

Cellulase-gamanase solution - add nine volumes of cellulase solution to one volume of the gamanase preparation and mix thoroughly. Filter through a Whatman GF/A glass micro-fibre filter circle held in a Hartley type three-piece funnel.

In Vivo Test of the Infusion Device. Before the infusion device was used to deliver micro-volume of a heparin solution, the amount of the anticoagulant required to delay the normal clotting time from 1.02 min to > 15 min was determined. An intraperitoneal silicone catheter was inserted by way of a trocar needle into an anesthetized Wistar rat, and the external catheter end was connected to the flow rate testing assembly. With a glass hollow fibre flow moderator having a flow rate of 50 plitre/hr at 48 kPa driving pressure, it was found to require about 25 IU/kg/hr to obtain a Lee-White...

This paper presents results from a study of assemblies composed of glass fibre reinforced epoxy composites. First, tests performed to produce mixed mode fracture envelopes are presented. Then results from tests on lap shear and L-stiffener specimens are given. These enabled failure mechanisms to be examined in more detail using an image analysis technique to quantify local strain fields. Finally the application of a fracture-mechanics-based analysis to predict the failure loads of top-hat stiffeners with and without implanted bond-line defects is described. Correlation between test results and predictions is reasonable, but special attention is needed to account for size effects and micro-structural variations induced by the assembly process.
