Advances in research on velocity distribution and bed-load transport in unsteady open-channel flow

Shui kexue jinzhan, 2012
The vertical velocity profile and bed-load transport in unsteady open-channel flow are major concerns of hydraulics and mechanics of sediment transport.In recent years,many researchers have come to do some serious explorations into the nature of the ...

Engineering Concentration‐Dependent Intravitreal Mobility via Cyclic Arginine‐Enriched Nanocarrier Surface Modification: In Vivo Proof‐of‐Concept in a Porcine Large Animal Model

Advanced Healthcare Materials, EarlyView.
In this study, Hammer et al. highlight cyclic‐arginine surface engineering as a highly biocompatible, controllable, and concentration‐dependent regulator of intravitreal nanoparticle mobility in vivo in a translational large animal model. The cyclic arginine surface‐modification supports the development of next‐generation biomaterials for long‐acting ...

Spatially Controlled Embedded Bioprinting of Prevascularized Spheroids‐Containing Biopatch Enables Functional Skin Regeneration

Advanced Healthcare Materials, EarlyView.
A spatially controlled embedded bioprinting strategy enables precise engineering of prevascularized multicellular spheroids within skin‐derived dECM bioinks. Optimized spheroid size, composition, and spacing promote vascular maturation, paracrine signaling, and tissue integration, resulting in enhanced angiogenesis, blood perfusion, and functional skin

Evaluation of an acoustic Doppler technique for bed-load transport measurements in sand-bed Rivers

E3S Web of Conferences, 2018
The bottom tracking (BT) feature of the acoustic Doppler current profilers (ADCP) have emerged as a promising technique in evaluating the bed load. Strong statistical correlations are reported between the ADCP BT velocity and the transport rate obtained ...

STUDY ON THE BED LOAD TRANSPORT BY STEEP TUNNEL

PROCEEDINGS OF HYDRAULIC ENGINEERING, 2003
Sediment bypass system has been proposed as a countermeasure against sedimentation and turbid effluence that occur in reservoirs over long period of operation. In ordcr to provide a guide for reasonable design of such bypass tunnels, the flow with a movable sediment bed in a steep-sloped pipe has been studied both experimentally and numerically.

PLL‐g‐HPA Hydrogel Microneedles Loaded With Rhoifolin Target Macrophages to Alleviate Fibroblast Senescence for Diabetic Wound Healing

Advanced Healthcare Materials, EarlyView.
Diabetic wound healing is hindered by a pathological crosstalk wherein elevated IL‐11 induces M1 macrophage polarization, leading to IL‐1β/IL‐6 release and subsequent fibroblast senescence via RAS/p38MAPK/p53/E2F1 signaling. Here, we develop a Gel@M‐Rho microneedle patch that delivers rhoifolin‐loaded, macrophage membrane‐coated nanoparticles to target
