Purpose The purpose this in vitro study was to investigate effect 3 orientations on physical and mechanical properties microstructure alumina dental ceramics. Material methods microstructures different oriented ceramics (ZX, ZY, XY) w...
In fabricating flowmeters, the meter's calibration is its final and accuracy determining step that comprises a great time consumption relative to its completion from its single component parts. Thus calibration (unless the respective time of calibration for a flow meter is not minimized) may represent a relevant contribution to fabrication costs. High-accuracy liquid flow calibration facilities...
In a national survey of US dairy producers, only 2.7 +/- 0.5% of Holstein dairy operations reported achieving recommended target ranges of age < or = 24 months and body weight (BW) > or = 550 kg at first calving. Allowing for wider target ranges, still only 14.6 +/- 1.3% of Holstein dairy operations reported achieving age < or = 25 months and BW > or = 544.3 kg at first calving. Ages of individ...
Background and purpose: The chromic catgut sutures are the most common suture materials in surgical operations. The purpose of this in-vivo study was to evaluate the histopathological inflammatory reaction incited by four different kinds of catgut suture materials. Materials and methods: Twenty five adult New Zealand White rabbits, weighing approximately 2-3 kg, were divided into 5 groups ...
Thirty persons arrested at Frankfurt airport for smuggling internally concealed cocaine in 1993/1994 were investigated. An X-ray examination (in all 30 cases), immunochemical examination of urine (in 27 cases) and of saliva (in 20 cases) was performed in parallel. An X-ray examination gave positive results in all examined persons. EMIT cocaine metabolite assay (cut off 300 ng benzoylecgonine (B...
