Carotid Velocities Determine Cerebral Blood Flow Deficits in Elderly Men with Carotid Stenosis <50% [PDF]
International Journal of Vascular Medicine, 2012 To examine if mild carotid stenosis correlates with silent vascular brain changes, we studied a prospective population-based cohort “Men born in 1914.” Data from followups at ages 68 and 81, have been used. Carotid ultrasound was performed at age 81, and cerebral blood flow (CBF) was measured with SPECT at age 82.

Study on flow around straight-bladed vertical axis wind turbine under low tip speed ratio
Journal of Fluid Science and Technology, 2014 The flow field around a vertical axis wind turbine (VAWT) is very complicated because the blades pass in non-uniform flow field by the blade wake during rotation.

Galactic rotation curves in modified gravity with non-minimal coupling between matter and geometry [PDF]
, 2010 We investigate the possibility that the behavior of the rotational velocities of test particles gravitating around galaxies can be explained in the framework of modified gravity models with non-minimal matter-geometry coupling. Generally, the dynamics of

JUMP ABILITY AND FORCE-VELOCITY PROFILE IN RHYTHMIC GYMNASTICS
Science of Gymnastics Journal, 2023 The jump is one of the main body elements in Rhythmic Gymnastics (RG). To perform it correctly, gymnasts must develop appropriate force and velocity levels to reach enough jump height to show the body shape during flight, as defined by the RG Code of ...
