Hydraulic reconstruction of catastrophic drainage from the Late Glacial, Lake Fraser, British Columbia, Canada

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

Balance Disorders in Young and Middle‐Aged Adults: NHANES, 2001–2004 and 2021–2023

open access: yesThe Laryngoscope, EarlyView.
This study presents nationally‐representative estimates from two health exam surveys, NHANES 2001–2004 and 2021–2023. In the two decades between test periods, scores on the modified Romberg screening test for balance function demonstrated significantly better age‐specific performance in 2021–2023.

Prediction of unsteady blade loads of a wind turbine using RANS and vorticity transport methodologies

open access: yes, 2010
Numerical simulations of the NREL phase VI wind turbine operating in yawed conditions have been performed using two computational methods; one based on the solution of the Reynolds-averaged Navier-Stokes equations (RANS) using unstructured overset meshes

UNSTEADY VELOCITY PIV MEASUREMENTS AND 3D NUMERICAL CALCULATION COMPATISONS INSIDE THE IMPELLER OF A RADIAL PUMP MODEL [PDF]

open access: yes, 2013
PIV measurements were performed at mid hub section inside the impeller of a vaned diffuser pump model working with air. Several previous papers have already presented part of impeller flow characteristics mainly for vaneless diffuser and near nominal ...

Pulsating flow and convective heat transfer in a cavity with inlet and outlet sections

open access: yes, 2009
This paper deals with the study of 2-D, laminar, pulsating flow inside a heated rectangular cavity with different aspect ratios. The cooling liquid (water with temperature dependent viscosity and thermal conductivity) comes and leaves the cavity via ...

Uncertainty in aquatic greenhouse gas flux estimates arises from subjective processing of floating chamber time series

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Accurate quantification of greenhouse gas (GHG) fluxes from aquatic systems is essential for constraining regional and global carbon budgets. Closed floating chambers are widely used to measure carbon dioxide (CO2) and methane (CH4) fluxes at the water–air interface, yet large uncertainties persist due to subjective processing of chamber time ...

Coupling Between Thermal Oscillations in the Surface of a Micro-Cylinder and Vortex Shedding

open access: yes, 2007
his article studies the coupling between prescribed thermal oscillations in the surface of a micro-cylinder and vortex shedding. We deal with the unsteady, laminar, compressible flow regime where the aerodynamics forces have a periodic behavior.
