INTRODUCTION Total knee prostheses with a mobile-bearing insert were developed to provide nonconstrained joint range of motion while reducing friction forces. The purpose of this study was, based on weightbearing X-rays, to evaluate the mobility of the polyethylene tibial insert in relation to the femoral and tibial components. We studied the results of a cementless total knee arthroplasty (TKA...

The ease and convenience of a hot-wire cutter for the separation of wells from PVC radioimmunoassay trays has been demonstrated.' In constructing a similar apparatus, it was felt that a worthwhile simplification could be achieved by arranging to push the PVC tray past a fixed hot wire. The wire can simply be held under spring tension, and the springloaded telescopic arm previously employed' be ...

the possibility of applying membrane distillation to support the fermentation process was investigated. the capillary polypropylene membranes were assembled in the membrane modules. the studies were carried out using the standard solutions containing the compounds frequently occurring in the broths such as ethanol, citric, acetic and lactic acids, glycerol and 1,3-propanediol. the performance o...

When a glass is lifted from tray, there challenge for the waiter. He must quickly compensate reduction in weight of tray to keep it balanced. This compensation easily achieved if waiter lifts himself. Because he has, himself, initiated action, can predict timing and magnitude perturbation respond (via holding hand) accordingly. In this study, we examined coordination when either one or two peop...

Impression procedure forms the basis of a successful Removable Partial Denture however, in distal extension bases the residual ridge must be recorded in functional form and the remaining natural teeth in an anatomic form. Zinc oxide eugenol impression paste is a material of choice for functional impression whilst irreversible hydrocolloid is suitable for an anatomic impression. Therefore two-pa...

Gaining access into the oral cavity of patients with limited mouth opening is difficult and rehabilitation of such patients is a challenge. The loaded impression tray is a bulky item that needs to be placed intraorally. In patients with microstomia, obtaining accurate impression using conventional techniques is difficult due to limited mouth opening and thus alternate clinical procedures need t...

Aim: This article describes an alternative preliminary impression technique for an infant with cleft palate. Methodology: A 3 day old male infant with cleft palate was referred to clinic for the fabrication of feeding plate, for the first impression a sterilized tea-spoon modified with a hole in the middle of spoon was used as a tray. Results: Modified spoon tray is easily accessible, cost effe...

The mixing behavior of the gas-liquid phase in three loop bioreactors was investigated. A gas-induced External Airlift Loop Bioreactor (EALB), a forced-liquid Vertical Tubular Loop Bioreactor (VTLB) and a forced-liquid Horizontal Tubular Loop Bioreactor (HTLB) were used for mixing studies as well as biomass production from natural gas. The effect of design parameters, riser to downcomer cro...
