The thermal antioxidant behavior of carbon black was studied in vulcanized cispolybutadiene and related to the surface chemistry of the black. Continuous and intermittent stress-relaxation and oxygen absorption measurements were employed to determine the antioxidant ability of the carbon blacks. The

High-Vinyl Polybutadiene (HVBD)/ cis-Polyisoprene (CPI) blends were characterized by Differential Scanning Calorimetry (DSC) and Positron Annihilation Lifetime Spectroscopy (PALS). A single DSC glass transition temperature T g is observed, whose composition dependence strongly deviates from additivi
## Abstract A 54 year old man was found to have a simple ureterocele with a dilated ureter. Ultrasonography demonstrated the ureterocele as an echoβfree structure at the base of the bladder without involvement of the bladder wall. The course of the dilated ureter and its entrance into the bladder w
