The objective of the present study was verify the influence of specimen dimensions on polymerization contraction stress of a self-cure dental composite and investigate the influence of confinement (expressed by the ratio between the bonded and unbonded area of the composite, or ‘C factor’) and volume of the specimen on stress values. The composite was inserted between the flat surfaces two glas...
OBJECTIVES The purpose of this study was to assess whether the newer stent delivery systems provide a stented lumen cross-sectional area (CSA) that is equal to the delivery balloon nominal dimensions. BACKGROUND First generation stents were often not adequately expanded with their delivery system and frequently required higher pressure or a larger balloon after deployment. Newer stents were d...
Blood microvessels in the membraneous lateral wall of the cochlea were examined using intravital microscopic techniques. A video analysis system made serial diameter measurements at 1 micron intervals along the length of selected vessel segments during four experimental conditions. For each vessel segment, the serial measurements were statistically converted into a single diameter estimate, suc...
