Purpose: This study investigated the cuspal deflection in premolar teeth restored with different bulk-fill resin composites or without using a liner. Materials and Methods: 60 extracted human upper were used. The samples this divided into three main groups (20 for each) according to materials used; Each group was subdivided two subgroups presence of Standardized large MOD cavities prepared. dis...

Power quality (PQ) problems for renewable energy system (RES) is major challenge using these systems. Amplitude, frequency, and waveform important PQ parameters especially standalone or isolated In this paper we propose RES with wind turbine (WT) permanent magnet synchronous generator (PMSG) to feed different loads (liner, non-liner) through AC-DC-AC converter. The PMSG operate fuzzy logic iner...

LINER nuclei, which are present in many nearby galactic bulges, may be the manifestation of lowrate or low-radiative-efficiency accretion onto supermassive central black holes. However, it has been unclear whether the compact ultraviolet (UV) nuclear sources present in many LINERs are clusters of massive stars, rather than being directly related to the accretion process. We have used the Hubble...

We have reviewed 70 patients with bilateral simultaneous total hip arthroplasties to determine the rate of failure and to compare polyethylene wear and osteolysis between an implant with a cobalt-chrome head and Hylamer liner with that of a zirconia head and Hylamer liner. The mean thickness of the polyethylene liner was 11.0 mm (8.8 to 12.2) in the hip with a zirconia head and 10.7 mm (8.8 to ...

It has been suggested that the wear of ultra-high molecular weight polyethylene (UHMWPE) in total hip replacement is substantially reduced when the femoral head is ceramic rather than metal. However, studies of alumina and zirconia ceramic femoral heads on the penetration of an UHMWPE liner in vivo have given conflicting results. The purpose of this study was to examine the surface characterist...
