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...
متن کاملRecessed 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.
متن کاملTray 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...
متن کاملA decomposition method for synthesizing complex column configurations using tray-by-tray GDP models
Abstract This paper describes an optimization procedure for the synthesis of complex distillation configurations. A superstructure based on the Reversible Distillation Sequence Model (RDSM) is proposed embedding all possible alternative designs using tray-by-tray models. Generalized Disjunctive Programming (GDP) is used to model the superstructure. Due to the large size and complexity of the fo...
متن کاملSalam model from branes
We explore the possibility of embedding the Pati–Salam model in the context of Type I brane models. We study a generic model with U(4) C × U(2) L × U(2) R gauge symmetry and matter fields compatible with a Type I brane configuration. Examining the anomaly cancellation conditions of the surplus abelian symmetries we find an alternative hypercharge embedding that is compatible with a low string/b...
