Effect of Laminar Pulsatile Fluid Flow on Separation of Volatile Organic Compounds from Aqueous Solution by a Hollow Fiber Membrane-Based Process [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2022 In this study, a laminar pulsatile fluid flow was used for the separation of benzene, toluene, ethylbenzene, and xylene isomers (BTEX) from aqueous solutions. Polyether sulfone hollow fiber membrane has been applied to this process.

Pulsation of anastomotic vortex veins in pachychoroid spectrum diseases
Scientific Reports, 2021 Accumulating evidence points to pachychoroid possibly being caused by vortex vein congestion which results in remodeling of choroidal drainage routes via intervortex vein anastomosis. This hypothesis prompted us to investigate vortex vein hemodynamics by

Physics linkages between arterial stiffness, cerebrovascular flow and cognitive impairment
Veins and Lymphatics, 2022 Background. Reduced cerebrovascular flow and localized hypoperfusion have been widely associated with various forms of cognitive impairment. Vascular cognitive impairment has also been associated with arterial stiffening and arteriosclerotic development.

Transitional turbulent flow in a stenosed coronary artery with a physiological pulsatile flow
International Journal for Numerical Methods in Biomedical Engineering, 2020 The turbulence in the blood flow, caused by plaque deposition on the arterial wall, increases by the combined effect of the complex plaque geometries and the pulsatile blood flow.

Pulsatile microvascular blood flow imaging by short-time Fourier transform analysis of ultrafast laser holographic interferometry [PDF]
, 2015 We report on wide-field imaging of pulsatile microvascular blood flow in the exposed cerebral cortex of a mouse by holographic interferometry. We recorded interferograms of laser light backscattered by the tissue, beating against an off-axis reference ...

Pulsatile Flow Measurement by a Speckle Triangle Assessment
Frontiers in Physics, 2021 The blood flow in the coronary artery (CA) is pulsatile and much higher than that measured in the brain, retina, and skin before. Its quantitative measurement is medically significant in the coronary artery bypass grafting (CABG).
