Molecular weight of starch decreased

substantially in the dose range of the study. The melt viscosity of LDPE/RTPS blend decreased whereas crystallinity of LDPE phase increased CAL-101 chemical structure with the incorporation of RTPS. No significant change in the carbonyl index and thermal stability of the blends was observed in the dose range studied; therefore, the observed changes in the physical and thermal properties of the blends were attributed primarily to the kinetic factors affecting crystallization and time-dependent phase separation process. Biodegradability of blends varied with the radiation dose imparted to starch component of blend, suggesting better encapsulation of RTPS by LDPE chains. (C) 2011 Wiley Periodicals, Inc.

“Certain terrestrial animals use sky polarization for navigation. Certain aquatic species have also been shown to orient according to a polarization stimulus, but the correlation between underwater polarization

and Sun position and hence the ability to use underwater polarization as a compass for navigation is still under debate. To examine this issue, we use theoretical equations for per cent polarization and electric vector (e-vector) orientation that account for the position of the Sun, refraction at the air-water interface and Rayleigh single scattering. The polarization patterns predicted by these theoretical equations are compared with measurements conducted in clear and semi-turbid coastal sea waters at 2 m and 5 m depth over sea floors of 6 m and 28 m depth. We find that the LY3039478 datasheet per cent polarization is correlated with the Sun’s elevation only in clear waters. We furthermore find

that the maximum value of the e-vector orientation angle equals the angle of refraction only in clear waters, in the horizontal viewing direction, over the deeper sea floor. We conclude that navigation by use Selleck Fedratinib of underwater polarization is possible under restricted conditions, i.e. in clear waters, primarily near the horizontal viewing direction, and in locations where the sea floor has limited effects on the light’s polarization.”
“Peripheral gangrene is rare in children. Protein C, protein S, and antithrombin deficiency, positivity for anticardiolipin antibodies or lupus anticoagulant and factor V Leiden mutation are important causes of thrombosis in the venous system. There is paucity of literature on the contribution of these factors in children with peripheral gangrene. We evaluated the role of aforementioned factors in children with peripheral gangrene. Protein S deficiency was seen in one case and another was transiently positive for lupus anticoagulant. None of the 11 age-and sex-matched normal controls had protein C, protein S, or antithrombin deficiency.
