As the nanosilica content increases, water absorption and ethanol absorption decreased. The particle size increases with increase of A200 content. PUSi hybrid emulsions are endowed with pseudo-plasticity. The apparent viscosity of

emulsions increased and then decreased with addition of A200. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 119: 3521-3530, 2011″
“In this study, the effect of Ag or Sb addition on the thermoelectric properties of PbTe including the Seebeck coefficient, the electrical resistivity, and the thermal conductivity, was studied in the temperature range from 323 to 723 K. The major carriers in the Ag-doped and the CX-6258 in vitro Sb-doped PbTe are holes and electrons, respectively. A degenerate semiconductor behavior in the electrical transport properties was observed in the Ag-doped, whereas the semi-metallic in the Sb-doped. It was suggested from the results of the Hall effect measurement and the Seebeck coefficient that the effective mass was significantly altered by the Sb-doping. The maximum dimensionless figure of merit, ZT, of Pb(1-x)Ag(x)Te

and Pb(1-x)Sb(x)Te (x = 0.1) alloys showed 0.27 and 0.62 at 723 K, respectively. Based on the analysis of the Seebeck coefficient of the Ag or the Sb-doped PbTe, the interaction between Ag and Sb in PbTe, as expected in the AgPb(m)SbTe(m+2) (LAST-m), may be supposed.

“The aim of this study was to evaluate any possible association of homocysteine with arterial stiffness indices in patients with essential arterial hypertension (AH), isolated office hypertension (IOH) and normotensive controls. The final cohort comprised 231 normotensives (NTs, 119 males), 480 patients

with IOH (196 males) and 1188 patients with essential AH (713 males). All patients were screened for plasma homocysteine levels and lipidaemic profile and underwent aortic compliance and wave reflection assessment by using carotid-femoral pulse wave velocity (PWVc-f) and aortic augmentation index corrected for heart rate (AIx) accordingly. In the total population, stepwise multiple AZD9291 concentration linear regression analysis showed that homocysteine levels remained a significant determinant of PWV (beta (SE): 0.056 (0.007), P<0.001) and AIx (beta (SE): 0.236 (0.052), P<0.001) independently of the traditional factors affecting arterial stiffness and wave reflection. When the three groups were examined separately, homocysteine levels remained an independent determinant of PWFc-f in all groups (NT: beta (SE): 0.070 (0.022), P = 0.002; IOH: beta (SE): 0.109 (0.015), P<0.001; AH: beta (SE): 0.040 (0.009), P<0.001). However, homocysteine levels remained an independent determinant of AIx only in the IOH and AH, but not in the NT group (IOH: beta (SE): 0.302 (0.124), P = 0.015; AH: beta (SE): 0.183 (0.057), P = 0.001; NT: beta (SE): 0.308 (0.240), P = 0.200).
