“The thermally induced ultrasound emissions from printable semiconductor nanoparticles produced by the application of input pulses are demonstrated on different substrates. Printing processes that use dispersion liquids containing nanoparticles make it possible to generate ultrasound waves on flexible graphite sheets. We argue that the emission efficiency, which is the ratio

of the ultrasound pressure to the input power, is greatly affected by the thermal effusivity of the nanoparticles, especially for the shell material in core-shell structured nanoparticles. (C) 2010 American Institute of Physics. [doi:10.1063/1.3483946]“
“Sphingomonas pituitosa excretes the capsular exopolysaccharide PS-EDIV into the culture broth augmenting considerably its fluid viscosity. Since this change particularly IPI-145 mw affects key processes like mixing and transport during the microbial production, this work was aimed at the theological characterization of the polymer-containing culture broth of S. pituitosa. The study included investigations on basic properties of the culture broth, but also on the dependence of the biomass-polymer-solution properties on different physicochemical post-cultivation treatment steps like variations of temperature, pH-value or concentration of salts. The essential result is the characterization of the viscoelastic behavior of the culture

broth, which was more gel-like than sol-like and exhibited slight elastic properties. This theological behavior showed that the PS-EDIV culture broth formed non-Newtonian www.selleckchem.com/products/acy-738.html fluids, indicating that it is a pseudoplastic biopolymer. MCC950 chemical structure with yield stress appearance and exhibits thixotropic properties. Rheograms were fitted to the Herschel-Bulkley model. The amplitude sweep

revealed a deformation of 21% as the limiting value of the linear viscoelastic interval. Furthermore, the PS-EDIV culture broth showed a high viscosity which was strongly influenced by salt type and concentration but weakly influenced by temperature and pH-value within the investigated experimental boundaries.

“A terminology and standardized classification has yet to be developed for those complications arising directly from the insertion of synthetic (prostheses) and biological (grafts) materials in female pelvic floor surgery.

This report on the above terminology and classification combines the input of members of the Standardization and Terminology Committees of two International Organizations, the International Urogynecological Association (IUGA) and the International Continence Society (ICS) and a Joint IUGA/ICS Working Group on Complications Terminology, assisted at intervals by many expert external referees. An extensive process of 11 rounds of internal and external review took place with exhaustive examination of each aspect of the terminology and classification.
