Mechanical properties like tensile strength, tear resistance, abrasion resistance, and compression set were found out. Swelling values of the vulcanizates as a measure of crosslink densities were also determined. Optimum dosage of ZOBS and a combination of ZOB and ZPS were also derived and found that capped ZnO is superior in NR vulcanization to conventional ZnO in improving cure properties including scorch safety and

mechanical properties. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012″
“This Bindarit study aims to analyze serum albumin levels (SAL) in relation to concentrations of vascular endothelial growth factor (VEGF) from peripheral plasma, infundibular Ilomastat cell line plasma, peritoneal fluids and the peritoneal burden of VEGF of patients with epithelial ovarian cancer.

Exploratory analyses of SAL in 39 patients and its relation to mean concentrations of VEGF from the origins are described above. Statistical analyses comprised Student’s t test, Mann-Whitney test and Pearson’s and Spearman’s correlation coefficient.

Both infundibular concentrations of VEGF and the peritoneal burden of VEGF showed significant differences between SAL dichotomized at 3 g/dl. Concentrations of VEGF in peritoneal fluids were not significant in relation to SAL.

Peripheral plasma VEGF levels did not show any linear correlation with SAL. Indeed, SAL showed a significant negative linear correlation (p < 0.001) to infundibular plasma as well as the peritoneal burden of VEGF (p = 0.004).

Infundibular mean concentrations of VEGF may contribute to reduce SAL in advanced staging rather than the peripheral plasma concentrations of this glycoprotein. The peritoneal burden of VEGF may also aid in decreasing levels of serum albumin.”
“The ternary perovskite system PbTiO3-Bi(Zn1/2Ti1/2)O-3-Bi(Mg1/2Ti1/2)O-3 was investigated in an attempt selleck to capture the enhanced tetragonality of the PbTiO3-Bi(Zn1/2Ti1/2)O-3 binary

system at a morphotropic phase boundary (MPB) to improve piezoelectric performance. Results from the (1-x)[0.75 PbTiO3-0.25Bi(Zn1/2Ti1/2)O-3]-(x)Bi(Mg1/2Ti1/2)O-3 pseudo-binary solution indicate the formation of an MPB-type phase boundary with a high T-C (585 degrees C at x = 0.55). Multiple dielectric transitions were observed in a region of the ternary diagram characterized by high occupancy of the A-site by Bi3+ (>40%) and the B-site by ferroelectrically active cations (>70%). Temperature-dependent diffraction studies revealed the persistence of a tetragonal structure in at least a subset of the crystal to the higher temperature dielectric transition.
