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.

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

High Pressure Torsion: from Laminar Flow to Turbulence

, 2017
We analyzed experimentally and theoretically deviations from the simple High Pressure Torsion (HPT) scheme. We showed that the nature of the plastic flow and the deformed state of the sample under HPT depends on the structure and mechanical properties of

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-

Laminar, turbulent, and inertial shear-thickening regimes in channel flow of neutrally buoyant particle suspensions. [PDF]

Physical Review Letters, 2014
The aim of this Letter is to characterize the flow regimes of suspensions of finite-size rigid particles in a viscous fluid at finite inertia. We explore the system behavior as a function of the particle volume fraction and the Reynolds number (the ratio

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

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.

Turbulent-laminar patterns in plane Poiseuille flow [PDF]

, 2014
Turbulent-laminar banded patterns in plane Poiseuille flow are studied via direct numerical simulations in a tilted and translating computational domain using a parallel version of the pseudospectral code Channelflow. 3D visualizations via the streamwise

Visualizing the spatiotemporal map of Rac activation in bovine aortic endothelial cells under laminar and disturbed flows. [PDF]

PLoS ONE, 2017
Disturbed flow can eliminate the alignment of endothelial cells in the direction of laminar flow, and significantly impacts on atherosclerosis in collateral arteries near the bifurcation and high curvature regions. While shear stress induced Rac polarity
