Study on Friction Loss of Carcass in Un-bonded Flexible Riser

Shiyou jixie, 2018
With the continuous development of offshore oil and gas resources, the application of un-bonded flexible risers has become more widespread. When the vessel hoisting flexible riser on the surface of the water experience irregular movement, the flexible ...

An analytical approach for predicting the fillet and contact stresses in symmetric and asymmetric spur gears under frictional mesh assumptions

Results in Engineering
A precise estimation of the bending and contact stresses, as well as the true friction value during the gear mesh, are critical aspects of a cost-effective and safe gear design.

Turbulence Intensity Scaling: A Fugue

Fluids, 2019
We study streamwise turbulence intensity definitions using smooth- and rough-wall pipe flow measurements made in the Princeton Superpipe. Scaling of turbulence intensity with the bulk (and friction) Reynolds number is provided for the definitions.

THE FRICTION FACTOR OF THE METALLIC WIRE

Sen'i Gakkaishi, 1976
The friction factor (Pressure drop coefficient) λ of the metallic wire was obtained by measuring the drop in pressure at different values of velocities of the air in a given length of a tube with very thin rectangular cross section, in which the surface of the bottom plane was covered with the metallic wires or with the flat model wires set in parallel

Extracellular matrix remodeling and immune reprogramming drive residual tumor progression of liver cancer after incomplete microwave ablation

Molecular Oncology, EarlyView.
Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

RESEARCH OF ADAPTIVE FRICTION CLUTCH WITH DIFFERENTIATED FRICTION PAIRS

Advanced Engineering Research, 2011
The problem of the clutch operation accuracy increase without introducing material changes into its construction is solved on the ground of N.D. Verner's construction of the adaptive lamellar clutch which friction group consists of disks made from the ...

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

Molecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

A Review of Pressure Drop and Mixing Characteristics in Passive Mixers Involving Miscible Liquids

Micromachines
The present review focuses on the recent studies carried out in passive micromixers for understanding the hydrodynamics and transport phenomena of miscible liquid–liquid (LL) systems in terms of pressure drop and mixing indices.

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.
