The purpose of this study was to compare the range of motion (ROM) of conventional total knee arthroplasty (TKA) using high-flexion, posterior cruciate ligament (PCL) stabilized prostheses and the ROM of conventional knee arthroplasty using navigation-assisted TKA, with mobile-bearing, cruciate ligament-retaining knees. Fifty conventional TKAs with(More)
Natural manganese ore (NMO) catalysts were characterized and tested in the selective catalytic oxidation of ammonia to nitrogen oxides under dilute conditions. Also, the oxidation of ammonia (NH(3)) was carried out using pure MnO(2), Mn(2)O(3) for comparing with the activity. It is found that the activity of NMO was similar to that of MnO(2) at low(More)
The present paper examined the photocatalytic degradation (PCD) of gas-phase trichloroethylene (TCE) over thin-film TiO2. A large-scale treatment of TCE was carried out using scale-up continuous flow photo-reactor in which nine reactors were arranged in parallel and series. The parallel or serial arrangement is a significant factor to determine the special(More)
