Controlled release of testosterone using silicone rubber.

Physical properties of silicone rubber.

2 Mechanical engineer, USAMBRL. 3 Major, Army Medical Specialist Corps, USAMBRL. ROOM-TEMPERATURE-VULCANIZING (RTV) silicone rubber is a versatile material and easy to handle. The ingredients from which it is formed are thick liquids that vulcanize at room temperature within a short period of time after the catalyst is added. Depending upon the relative amounts of solid and foam ingredients, th...

'Silicone rubber' lenses in aphakia.

Tesicon, one of the commercially available 'silicone rubber' lenses, was used in the correction of aphakic patients. In 74% of cases the lenses were considered successful for a daily wear regimen by the patient. Furthermore, a small number of patients could wear this lens without interruption for 3 to 6 days at a time. Despite this good acceptance by patients, corneal problems (mainly staining)...

Assembly Time Minimization of a Particular Placement Machine

A new algorithm for a component placement machine is proposed in this study. The new algorithm is compared with former approaches on synthetically generated benchmark instances. It outperforms the former approaches by 3.28% on printed circuit board with 100 components to be placed. We prove that this new approach works better in a typical PCB mounted in the industry, so can be applicable to the...

A novel cell exclusion zone assay with a barrier made from room temperature vulcanizing silicone rubber

OBJECTIVE To examine the usefulness of room temperature vulcanizing (RTV) silicone rubber as a barrier material for cell exclusion zone assays. METHODS We created barriers using three types of RTV silicone rubber with differing viscosities. We then assessed the adherence of these barriers to culture dishes and their ease of removal from the dishes. We tested the effect of the newly created ba...
