The detection of Aspergillus galactomannan antigen (GM) with the Platelia Aspergillus (PA) enzyme-linked immunosorbent assay (Bio-Rad) is a method widely used for the diagnosis of invasive aspergillosis (IA), a life-threatening fungal infection (3, 7). In the last 2 years, several authors found GM in patients treated with piperacillin-tazobactam (TZP) and in TZP vials (1, 6, 8, 10, 11) while ot...

This study systematically investigated the electric direct current (DC) dependence of plastic flow behavior in a densified tetragonal ZrO2 polycrystal (TZP). Consequently, we observed an optimal density for tensile ductility. The maximum elongation 135% was achieved under 250 mA?mm?2 at furnace temperature 1000°C and initial strain rate 1 × 10?3 s?1. diffusional mass transport TZP accelerated b...

X-ray imaging in differential interference contrast (DIC) with submicrometer optical resolution was performed by using a twin zone plate (TZP) setup generating focal spots closely spaced within the TZP spatial resolution of 160 nm. Optical path differences introduced by the sample are recorded by a CCD camera in a standard full-field imaging and by an aperture photodiode in a standard scanning ...

Different volume fractions (1.3, 2.6, and 7.6 Vol.%) of carbon nanotubes (CNTs) were dispersed within 8Y-TZP nanopowders. Mixed powder specimens were subsequently processed by spark plasma sintering (SPS) and effects of CNTs on the sintering process of 8Y-TZP/CNT composites was studied. Maintenance of CNTs through the SPS process was confirmed using TEM and Raman Spectroscopy. Studies on the si...

+*Clarke, I C, Brown, S, Pezzotti, G, Green, D D, T. Donaldson, T D +Loma Linda University, Loma Linda, CA [email protected] INTRODUCTION The feature that makes yttria-stabilized, tetragonal zirconia polycrystalline (Y-TZP) ceramic both strong and fatigue resistant is its ability to partially transform under stress from tetragonal phase to its monoclinic phase, i.e. an inherent metastability [1]....

The purpose of this study was to conduct static load-bearing tests on 4-unit Y-TZP all-ceramic fixed partial denture (FPD) frameworks with different cross-sectional areas and forms to evaluate the influence of connector design on fracture load. Each of the central, mesial and distal connectors was prepared with one of 2 different cross-sectional areas and one of 3 different forms (one circular ...
