Unsteady stagnation-point heat transfer during passage of a concentrated vortex [PDF]

The unsteady boundary layer due to a single rectilinear vortex filament approaching a 2-D stagnation point is investigated. Assuming the vortex remains far from the surface, incompressible potential flow theory is used to determine the time dependent ...

New Drain Spacing Formulas Using the Variational Iteration Method

Irrigation and Drainage, EarlyView.
ABSTRACT In this study, the drain spacing is computed using the variational iteration method (VIM) to the linearized Boussinesq equation. By applying at most two iterations of the VIM method under three different initial condition scenarios, three equations for drain spacing calculation were derived. These equations predict values of drain spacing that

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

The 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.

Experimental and Numerical Investigation of Unforced unsteadiness in a Vaneless Radial Diffuser [PDF]

, 2011
The paper reports combined experimental and numerical investigations of unforced un- steadiness in a vaneless radial diffuser. Experimental data were obtained within the diffuser using stereoscopic time resolved Particle Image Velocimetry (PIV) recording

Development and Validation of a Brief Fall Questionnaire (FALL‐HD) for Patients with Huntington's Disease

Movement Disorders Clinical Practice, EarlyView.
ABSTRACT Background Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder caused by a mutation in the huntingtin gene on chromosome 4, leading to progressive cognitive decline, motor impairment, and functional disability. Falls represent the leading cause of nursing home placement in HD.

Voice and Speech in Atypical Parkinsonian Disorders

Movement Disorders Clinical Practice, EarlyView.
Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics.

Supersonic axial-flow fan flutter [PDF]

Lane's (1957) analytical formulation of the unsteady pressure distribution on an oscillating two-dimensional flat plate cascade in supersonic axial flow has been developed into a computer code. This unsteady aerodynamic code has shown good agreement with

Treatment Continuation and Long‐Term Outcomes of Perampanel in Primary Orthostatic Tremor; A Cohort Study

Movement Disorders Clinical Practice, EarlyView.
Background Primary orthostatic tremor (POT) is a rare hyperkinetic movement disorder with limited and largely ineffective treatment options. Perampanel has been suggested as a therapy, but has so far only been investigated in small studies with short duration.

Analysis of two-dimensional incompressible flow past airfoils using unsteady Navier-Stokes equations [PDF]

The conservative form of the unsteady Navier-Stokes equations in terms of vorticity and stream function in generalized curvilinear coordinates are used to analyze the flow structure of steady separation and unsteady flow with massive separation.

The Combined Effects of Variable Viscosity and Thermal Conductivity of An Unsteady Casson Fluid Flow Along a Vertical Porous Channel With Convective Cooling Walls, Using the Bivariate Spectral Local Linearization Method

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the combined impact of different thermal conductivity and viscosity on unsteady non‐Newtonian Casson fluid flow of incompressible, electrical conductivity in a porous vertical channel with convective cooling walls, uniform magnetic field, and constant pressure gradient.
