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 کاملAssay of the antibiotic activity of serum.
One of the drawbacks of the "tube dilution" method for the assay of antibiotics in human serum has been illustrated by utilizing serum-sensitive and serum-resistant strains of Escherichia coli. In the case of serum-sensitive strains, it was found that fresh serum alone may account for the same degree of inhibition and thus yield minimal inhibitory concentrations identical to those obtained with...
متن کاملPreparation of agar wells for antibiotic assay.
A variety of devices such as stainless-steel or ceramic cylinders, single or multiple in design, and paper discs of several sizes are commonly used for antibiotic assays performed by the agar diffusion method. Holes cut in agar (agar wells) are wells with melted agar is often necessary to obtain uniform inhibition zones (2). This note describes a method for the preparation of agar-well plates w...
متن کاملRecessed pan tray.

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...
