Evaluation the Hydraulic Aspects of Stepped Labyrinth Spillway [PDF]
Engineering and Technology Journal, 2014 This study was adopted a new concept to enhance performance of stepped spillway towards more dissipation of kinetic energy along chute face through increases interlocking surface areas between the mainstream and trapping cavity recirculation vortices on ...

Effect of fractional blood flow on plasma skimming in the microvasculature [PDF]
Physical Review E, 2017 Although redistribution of red blood cells at bifurcated vessels is highly dependent on flow rate, it is still challenging to quantitatively express the dependency of flow rate in plasma skimming due to nonlinear cellular interactions. We suggest a plasma skimming model that can involve the effect of fractional blood flow at each bifurcation point. For

Spatial distributions of red blood cells significantly alter local haemodynamics. [PDF]
PLoS ONE, 2014 Although bulk changes in red blood cell concentration between vessels have been well characterised, local distributions are generally overlooked. Red blood cells aggregate, deform and migrate within vessels, forming heterogeneous distributions which have

Tracking of enrofloxacin antibiotic in the making of common middle eastern cheeses
Applied Food Research, 2021 Our study aims to determine the effects of different processes (skimming, pasteurizing, curding, pressing, boiling and salting) on enrofloxacin during the making of commonly consumed Middle Eastern products (Baladi, Akkawi, Halloum, Double Cream), which ...

Study of Conveniency of Using Stepped Spillway in Roller Compacted Concrete Dams (RCCD) [PDF]
Engineering and Technology Journal, 2009 A suggested design of Bastora stepped spillway has been taken as a prototype to build a physical wooden model with scale of 1:20 (Lm/Lp). Experiments have been carried out on the model with slope of upward inclined steps of 420, 280, 140 and 00.

Experimental study of skimming flow on the stepped spillway in the non-aerated area using PIV [PDF]
هیدرولیکUnderstanding the flow behavior over stepped spillways has been the subject of many previous studies. Most of the studies conducted on stepped spillways have been in skimming flow conditions and the aerated parts of the spillway.

Comparison of Energy Dissipation between Nappe and Skimming Flow Regimes on Stepped Chutes [PDF]
, 1994 For the last decades, stepped spillways have become a popular method for handling flood releases. The flow regime over a stepped chute can be either a nappe flow or skimming flow regime. The energy dissipation of both flow regimes are analysed.

FLOW CHARACTERISTICS OF SKIMMING FLOW IN A STEPPED CHANNEL
PROCEEDINGS OF HYDRAULIC ENGINEERING, 2004 Recently, research onto the hydraulics of stepped chutes was driven by needs for better design guidelines (OHTSU and YASUDA 1997, CHANSON and TOOMBES 2002, BOES and HAGER 2003). Although stepped channel flows are characterized by intense turbulence and strong flow aeration, most studies did not investigate the turbulence characteristics. In this study,
