In 1954 a project was started to systematically investigate the nondialyzable substances in human urine. Four reports1 have been presented describing the procedure for removing the insoluble material from urine preserved with toluene (10 ml/specimen) by high-speed continuous-flow centrifugation, after which a soft, buttery layer called “floating lipid fraction” (FF)2 by Smith (1) and Winkler (2...

This paper is concerned with the analysis of bending edge waves travelling in a thick Kirchhoff-type piezoelectric film resting on Winkler–Fuss foundation. The electromechanical coupling accounted for defining flexural rigidities to embrace and dielectric material constants. Dynamics solved analytically demonstrated numerically by assuming harmonic wave propagation. It observed that an increase...

RNA has been shown recently to playa prominent role in regulating gene expression in a wide variety of organisms. Natural examples of RNA-dependent gene regulation include modulation of transcription (Wassarman and Storz, 2000; Winkler et al., 2002), translation (Moller-Jensen et al., 200 I; Moller et al., 2002; Bartel, 2004), and the temporal stability of mRNA (Masse et al., 2003; Meister and ...
