548 to 0.193. The current density exponent of Black’s equation for SM+EM stressed samples is
similar to 1, suggesting that void had already been nucleated because of the SM-only test. The high intrinsic tensile stress in the line is suspected to be responsible for this early void nucleation. In the second part, we developed a Monte Carlo simulation model to estimate the void nucleation and growth time using the EM-only and SM+EM degradation tests. We found that at low percentile failures overall failure time is mainly growth dominated, whereas at high percentile failures overall failure time is nucleation dominated. Stress migration was found to shorten the nucleation time for all the samples. (C) 2011 American Institute of Physics. [doi:10.1063/1.3651385]“
“We investigated whether Merkel Baf-A1 concentration cell carcinoma (MCC) patients in France carry Merkel cell polyomavirus (MCPyV) and then identified strain variations. All frozen MCC specimens and 45% of formalin-fixed and paraffin-embedded specimens, but none of the non-MCC neuroendocrine carcinomas specimens, had MCPyV. Strains from
France and the United States were Rabusertib supplier similar.”
“In this article, we report on the extraction of Sr(II) ions from aqueous solution with a series of poly(N-vinyl imidazole)-based hydrogels. The hydrogels were synthesized by the crosslinking of N-vinyl imidazole with four different crosslinkers with ? rays as initiators. The well-characterized hydrogels were used as Sr(II) sorbents. Selleck Y-27632 Sr(II) uptake was determined with a colorimetric method with Rose Bengal anionic dye. Scanning electron microscopyenergy-dispersive spectroscopy analysis of the Sr(II)-loaded polymers was recorded to ascertain the uptake of Sr(II) ions. The experimental adsorption values were analyzed with the Freundlich and Temkin equations,
and the kinetics of adsorption were investigated with a pseudo-second-order sorption kinetic model. The results show that the equilibrium data fit well in the Freundlich isotherm and followed a pseudo-second-order kinetic model. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012″
“We present data from 17 languages on the frequency with which a common set of words is used in everyday language. The languages are drawn from six language families representing 65 per cent of the world’s 7000 languages. Our data were collected from linguistic corpora that record frequencies of use for the 200 meanings in the widely used Swadesh fundamental vocabulary. Our interest is to assess evidence for shared patterns of language use around the world, and for the relationship of language use to rates of lexical replacement, defined as the replacement of a word by a new unrelated or non-cognate word. Frequencies of use for words in the Swadesh list range from just a few per million words of speech to 191 000 or more.
