A circumferentially flanged tibial tray minimizes bone-tray shear micromotion.

Aseptic loosening of the tibial component is the major complication of total knee arthroplasty. There is an association between early excessive shear micromotion between the bone and the tray of the tibial component and late aseptic loosening. Using non-linear finite element analysis, whether a tibial tray with a circumferentially flanged rim and a mating cut in the proximal tibia could minimiz...

Solution methods for the tray optimization problem

In order to perform medical surgeries, hospitals keep large inventories of surgical instruments. These instruments need to be sterilized before each surgery. Typically the instruments are kept in trays. Multiple trays may be required for a single surgery, while a single tray may contain instruments that are required for multiple surgical procedures. The tray optimization problem (TOP) consists ...

Recessed pan tray.

W hile working in the classroom with orthopedically handicapped and multihandicapped pre-school children, the need arose for a piece of equipment that would permit a child to work with tactile stimulation activities as independently as possible while also freeing the teacher and aide to move about and work with several children simultaneously instead of being restricted to a one-to-one si tuation.

Tray Columns: Design

Distillation has remained an important separation technology for the chemical process industries. In 1997 it was reported in the journal Chemical Engineering that about 95% of all worldwide separation processes use this technology. In the USA alone, some 40000 distillation columns represent a capital investment of about US $8 billion. They consume the energy equivalent of approximately 1 billio...
