An experimental study is presented consisting of swash zone hydrodynamics, sediment transport flux estimates, and bed changes under a single dam-break-driven event over steep (1:7), movable sand bed. The provides resolved measurements instantaneous water depths, cross-shore flow velocities, sheet suspended concentrations, morphological response. ensemble-averaging 24 repetitions the allows conv...

The formation of thinning filaments is commonly observed previously to the break-up of a very viscous jet. This paper shows that a fluid under capillary forces cannot break-up through the uniform collapse of a filament. r 2003 Elsevier Inc. All rights reserved. MSC: 35Q30; 35R35; 74H35

This paper was concerned to simulate both wet and dry bed dam break problems. A high-resolution finite volume method (FVM) was employed to solve the one-dimensional (1D) and two-dimensional (2D) shallowwater equations (SWEs) using an unstructured Voronoi mesh grid. In this attempt, the robust local Lax-Friedrichs (LLxF) scheme was used for the calculating of the numerical flux at cells interfac...

OBJECTIVE To determine the circumstances under which pediatric psychologists believe it is ethical to break confidentiality when presented with adolescent health risk behavior. METHOD Members of the Society of Pediatric Psychology (N = 92) responded to a survey containing a vignette about an adolescent patient engaging in health-compromising behaviors. Participants rated the degree to which i...

Bird eggs should have high internal and external quality to maintain the economic life of the product and hence recognizing and understanding thefactors affecting egg quality have great importance. In this experiment, 18 healthy eggs were selected and then exposed to a 1.5 Tesla magnetic field. After this stage, 6 samples of them were immersed in sunflower oil and stored for two days. In ...

Propagation of incoherently soliton pairs in photorefractive crystals under steady-state conditions is studied. These soliton states can be generated when the two mutually incoherent optical beams with the same polarization and wavelength incident on the biased photorefractive crystal. Such soliton pairs can exist in bright-bright, dark-dark, gray-gray as well as in bright-dark types. In this p...
