Characterizing pulsatile blood flow in a specific carotid bifurcation: insights into hemodynamics and rheology models

AIMS Biophysics, 2023
This study uses laminar and turbulent flow models to investigate the blood flow dynamics in a specific carotid bifurcation. Pulsatile boundary conditions and the rigid carotid artery wall are considered.

Mist Flow Visualization for Round Jets in Aerosol Jet Printing

, 2018
With the microdroplets of water serving as light scattering particles, the mist flow patterns of round micro-jets can be visualized using the Aerosol Jet(R) direct-write system. The visualization images show that the laminar mist jet appears to extend to

Guided flows in coronal magnetic flux tubes [PDF]

, 2017
There is evidence for coronal plasma flows to break down into fragments and to be laminar. We investigate this effect by modeling flows confined along magnetic channels. We consider a full MHD model of a solar atmosphere box with a dipole magnetic field.

Stress and Vascular Responses: Atheroprotective Effect of Laminar Fluid Shear Stress in Endothelial Cells: Possible Role of Mitogen-Activated Protein Kinases

Journal of Pharmacological Sciences, 2003
Atherosclerosis preferentially occurs in areas of turbulent blood flow and low fluid shear stress, whereas laminar blood flow and high shear stress are atheroprotective.

How does flow in a pipe become turbulent?

, 2007
The transition to turbulence in pipe flow does not follow the scenario familiar from Rayleigh-Benard or Taylor-Couette flow since the laminar profile is stable against infinitesimal perturbations for all Reynolds numbers.

Comparison of allo-SCT, auto-SCT and chemotherapy for the treatment of patients with low- or intermediate-risk acute myeloid leukemia: a network meta-analysis

Stem Cell Research & Therapy
Background The therapeutic status of allogeneic stem cell transplantation (allo-SCT) as a post-remission treatment for patients with high-risk acute myeloid leukemia (AML) was well-accepted. However, the optimal treatment for patients with low/favorable-

Foam generation in a rotor—stator mixer = Schaumerzeugung in einem rotor—stator mischer [PDF]

, 1988
The foaming process of an aqueous liquid system with surface active agents and thickeners in a rotor-stator mixer has been studied.\ud \ud The foaming capacity of a rotor—stator mixer may be represented by a so-called mixing characteristic.

HSP70 governs permeability and mechanotransduction in primary human endothelial cells

FEBS Open Bio, EarlyView.
HSP70 chemical inhibition reduces endothelial cell proliferation and increases permeability, the latter supported by normal interendothelial junctional protein distribution. HSP70 also plays a role in shear stress response, a hemodynamic force naturally present in blood vessels and correlated with vessel protection.

The History of the Slotted Natural-Laminar-Flow Airfoil for Improved Fuel Efficiency

Aerospace
It is well established that increasing vehicle efficiency enables the achievement of N + 3 sustainable air travel goals. To this end, the integration of a slotted natural-laminar-flow airfoil with a transonic, truss-based commercial wing configuration is
