Flow and bathymetry in sharp open‐channel bends: Experiments and predictions [PDF]

Water Resources Research, 2008
This paper focuses on experiments and simulations conducted in very sharp open‐channel bends with flat and equilibrium bathymetry, corresponding to the initial and final phases of the erosion and deposition processes, respectively. The study of flow in curved open bends is relevant for flow in natural river configurations, as most river reaches are not

Experimental Investigation of Effect of Bank Roughness on Flow Patterns in a 90 Degree Sharp Bend [PDF]

علوم و مهندسی آبیاری, 2012
The present study has been conducted in a 90 degrees sharp bend to investigate the effect of bank roughness on flow patterns. Tests conducted under two different flow conditions, with Froude numbers equal to 0.17 and 0.4 and two different roughness sizes

Study of Streamlines under the Influence of Displacement of Submerged Vanes in Channel Width, and at the Upstream Area of a Cylindrical Bridge Pier in a 180 Degree Sharp Bend [PDF]

Journal of Hydraulic Structures, 2018
In this paper, submerged vanes were placed at the upstream area of a bridge pier located at the 90 degree angle. Then, using the laboratory equipment, a study of flow pattern was conducted throughout the bend, specifically around the pier and submerged ...

An Experimental Study of the Effect of a Small-Scale Rectangular Canal’s Wall Roughness on the Flow Patterns in a 90° Sharp Bend with a Radius of Curvature to the Bottom Width Ratio of 2 [PDF]

مهندسی منابع آب, 2014
The wetted perimeter’s roughness, the radius of curvature and its ratio to the bottom width affect the flow velocity and its patterns. This laboratory study was conducted in a 90° sharp bend flume with a rectangular cross-sectional area, and the radius ...

Early Impact of Childhood Opportunity on Neurocognitive Outcomes in Sickle Cell Disease

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neurocognitive impairment is a well‐recognized complication of sickle cell disease (SCD) that begins early in childhood and persists across development. While cerebrovascular injury contributes substantially to risk, neurocognitive deficits are also observed in children without overt or silent cerebral infarctions, suggesting ...

Design of modified structure multi-layer perceptron networks based on decision trees for the prediction of flow parameters in 90° open-channel bends

Engineering Applications of Computational Fluid Mechanics, 2016
A modified multi-layer perceptron (MLP) model based on decision trees (DT-MLP) is presented to predict velocity and water free-surface profiles in a 90° open-channel bend. The ability of the new hybrid model to predict the velocity and flow depth in a 90°

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Formation of the Great Bend and Enhanced Quaternary Incision of the Upper Yangtze River: New Insights from Low-Temperature Thermochronology and Tributary Morphology [PDF]

Lithosphere
The occurrence of a sharp turn along the upper course of the Yangtze River is referred to as the “Great Bend” and represents a large-scale drainage reorganization in response to the surface rise of the Tibetan Plateau.

Turbulence characteristics in sharp open-channel bends

Physics of Fluids, 2005
In spite of its importance, little is known about the turbulence characteristics in open-channel bends. This paper reports on an experimental investigation of turbulence in one cross section of an open-channel bend. Typical flow features are a bicellular pattern of cross-stream circulation (secondary flow) and a turbulence activity in the outer bend ...

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

FEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...
