Flow structure in a local meander bend of a gravel-bed river

Journal of Hydrology and Hydromechanics
This study investigates the spatial variability of flow structure in a natural meandering bend of the Kheir- Abad River, a gravel-bed mountain stream in southwestern Iran, with emphasis on velocity distribution, boundary shear stress, and secondary ...

Streamline and Isotherm Visual Analysis of Darcy–Forchheimer von Karman Spinning Flow of Maxwell Fluid Over a Stretching Disk With Quadratic Temperature‐Dependent Heat Source

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This research paper provides an extensive study of the effects of Darcy–Forchheimer von‐Karman spinning flow of Maxwell fluid across a stretching disk including the effect of heat generation based on a nonlinear function of temperature. The flow system is influenced by thermal radiations and Arrhenius activation energy.

Experimental Study on the Critical Condition of Armored Layer’s Breakage

工程科学与技术, 2008
:Mountain river’s beds are usually covered by armor layer. In this paper, the flume experiments are conducted to study the critical condition of armor layer’s breakage, by the increasing intensity of flow with a little range in the experiment.

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

The Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Surf and swash zone hydrodynamics forced by oblique, monochromatic waves in a wave basin with a smooth, impermeable beach

Applied Ocean Research
Beaches are coastal features that offer economic benefits, ecosystem services, and natural barriers against flooding. Sustainable management of beaches requires a firm understanding of hydrodynamics and sediment transport processes.

Physically Based New Formula for Cohesive Bed Erosion Rate [PDF]

علوم و مهندسی آبیاری, 2015
The currently most widely used erosion models are poorly based on physical principles and lack the ability to describe erosion of the consolidated sediment bed at increased shear stresses e.g. during a storm.

Healing Integrity Determines Meniscal Extrusion After Isolated Medial Meniscus Posterior Root Repair in Knees With No Lower Limb Malalignment

Arthroscopy, EarlyView.
Purpose To investigate changes in meniscal extrusion and meniscal healing status following root repair, and the relationship between meniscal extrusion and healing conditions. Methods Patients who underwent isolated root repair between 2019 and 2023 and consented to undergo second‐look arthroscopy to evaluate their healing condition (1 year ...

Harnessing plant‐based platform for low‐cost cellulosic sugar recovery from bioenergy crops

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The price of pure cellulase enzyme for the recovery of fermentable cellulosic sugars is one of the major challenges that limit the commercialization of second‐generation biofuels and bio‐based products. This work shows a means to greatly reduce the cost of cellulases. The abundant capacity of plants to synthesize and hyperaccumulate transgenic
