The effects of oxygen-plasma-treatment power on both the Armos fiber surface properties and Armos-fiber-reinforced poly(phthalazinone ether sulfone ketone) composite interfacial adhesion were investigated. The Armos fiber surface chemical composition, surface morphology and roughness, and surface wettability as a function of oxygen-plasma-treatment power were measured by X-ray photoelectron spectroscopy, scanning electronic microscopy, atomic force microscopy, and dynamic contact angle analysis. The results show that oxygen plasma treatment introduced a lot of reactive
functional groups onto the fiber surface, changed the surface morphology, increased Selleck EPZ-6438 the surface roughness, and enhanced the surface wettability. Additionally, the effect of the oxygen-plasma-treatment power on the composite interfacial adhesion was measured
by interlaminar shear strength with a short-beam bending test. Oxygen plasma treatment was an effective method for improving the composite interfacial properties by both chemical bonding and physical effects. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 121: 2804-2811, 2011″
“Background: Despite the high saturated fat content of dairy products, no clear association between dairy product intake and risk of myocardial infarction (MI) has been observed. Dairy products are the main source of conjugated linoleic acid (CLA; 18: BI-2536 2n-7t), which is produced by the ruminal biohydrogenation of grasses eaten by cows. Pasture-grazing dairy cows have more CLA in their milk than do grain-fed cows. Some animal models have reported beneficial effects of CLA on atherosclerosis.
Objective: The objective was
to determine the association between the 9c, 11t-CLA isomer in adipose tissue and risk of MI.
Design: The studied population consisted of 1813 incident cases of a first nonfatal acute MI and 1813 population-based controls matched for age, sex, and area of residence. All subjects lived in Costa Rica-a country that uses traditional pasture-grazing for dairy cows. Conditional logistic regression was used to estimate multivariate odds ratios and 95% PR-171 in vivo CIs.
Results: Adipose tissue 9c, 11t-CLA was associated with a lower risk of MI in basic and multivariate models. Compared with the lowest quintile, odds ratios and 95% CIs were 0.80 (0.61, 1.04) for the second, 0.86 (0.64, 1.14) for the third, 0.62 (0.46, 0.84) for the fourth, and 0.51 (0.36, 0.71) for the fifth quintiles (P for trend < 0.0001). Dairy intake was not associated with risk of MI, despite a strong risk associated with saturated fat intake.
Conclusion: 9c, 11t-CLA, which is present in meaningful amounts in the milk of pasture-grazed cows, might offset the adverse effect of the saturated fat content of dairy products. Am J Clin Nutr 2010; 92: 34-40.”
“Magnetic recording on bit patterned media with dot densities of 4 Tbit/in.(2) was simulated. Head field distributions of shielded, single pole write heads with various main pole widths were used for recording.
