Bridge pier flow interaction and its effect on the process of scouring [PDF]
, 2015 University of Technology Sydney. Faculty of Engineering and Information Technology.Previous investigations indicate that scour around bridge piers is a contributor in the failure of waterway bridges. Hence, it is essential to determine the accurate scour

Electrochemical Nitrate Reduction Reaction to Ammonia at Industrial‐Level Current Densities
Advanced Science, EarlyView.This review starts from the mechanism and theoretical basis of electrochemical nitrate reduction reaction (NO3−RR), and systematically summarizes and discusses the design strategies of industrial‐level current density catalysts. In addition, the progress of industrial‐level NO3−RR‐based electrolyzers, including flow reactor and membrane electrode ...

Effect of trapezoidal collars as a scour countermeasure around wing-wall abutments
Water Science and Engineering, 2018 Local scour around bridge abutments is a widespread problem that can result in structural failure. Collars can be used as a countermeasure to reduce the scour depth.

Laparoscopic Colorectal Surgery in the Era of Robotics: Evolution, Eclipse, or Equilibrium?
Annals of Gastroenterological Surgery, EarlyView.ABSTRACT Minimally invasive colorectal surgery has undergone a remarkable transformation over the past three decades. Laparoscopy, once viewed with skepticism, is now firmly established as a standard approach, supported by robust randomized trials demonstrating oncologic safety and improved recovery compared to open surgery.

Scour depth beneath a pipeline undergoing forced vibration
Theoretical and Applied Mechanics Letters, 2015 AbstractThis paper studies the coupling effect of the pipeline vibration on the seabed scour. A vertical two-dimensional model is applied to numerically investigate the local scour below a vibrating pipeline with different amplitudes and periods.

American Journal of Botany, EarlyView.Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.
