Comparison between Computations and Measurements of Bed Load Transport Rate in Nestos River, Greece

Procedia Engineering, 2016
AbstractIn the framework of diploma theses elaborated in the Division of Hydraulic Engineering, Department of Civil Engineering, Democritus University of Thrace, measurements of stream discharge and bed load transport rate were carried out at the outlet of the mountain part of Nestos River basin (northeastern Greece). In concrete terms, 68 measurements

Temporal variations of bed load transport rate and the grain size distribution of non-uniform size sediment during a constant flow rates [PDF]

MATEC Web of Conferences, 2018
Bedload transport rates at a point using both laboratory and field measurement vary with time, from almost zero to several folds of the mean rate. The need to carry out point measurements over a sufficiently long sampling period is very important to cover inconsistency in the transport rate during a short period of observation.

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

Advanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

Experimental study on characteristics of bed load transport over low-head, run-of-river dams

Shui kexue jinzhan, 2020
During flood period, the bed load deposited behind a run-of-river dam on a mountain river could be carried over the dam crest by the flow which would intensify sediment transport.

Bio‐Inspired Biopolymeric Implantable Platform for Localized and Sustained Drug Delivery in Solid Tumor Treatment

Advanced Functional Materials, EarlyView.
A bio‐inspired biopolymeric implantable drug delivery platform enables localized and sustained release of 7‐ethyl‐10‐hydroxycamptothecin (SN‐38) in solid tumor treatment. The three‐dimensional (3D) structured crosslinked‐chitosan implants are fabricated via 3D‐printed molds and provide drug release over 3 months, significantly inhibiting tumor growth ...

A probabilistic framework for the cover effect in bedrock erosion [PDF]

Earth Surface Dynamics, 2017
The cover effect in fluvial bedrock erosion is a major control on bedrock channel morphology and long-term channel dynamics. Here, we suggest a probabilistic framework for the description of the cover effect that can be applied to field, laboratory ...
