Experimental Study on Dry Friction Behavior of AlumiNm Alloy Casing

Shiyou jixie, 2022
In order to study the frictional and wear behavior of alumiNm alloy casing in gas drilling technology, under dry friction conditions, taking 40CrNmo steel as the pin and 7075 alumiNm alloy as the disc, by means of pin-disc wear test system, the effects ...

Stiffness of Contacts Between Rough Surfaces

, 2010
The effect of self-affine roughness on solid contact is examined with molecular dynamics and continuum calculations. The contact area and normal and lateral stiffnesses rise linearly with the applied load, and the load rises exponentially with decreasing

Total contact cast wall load in patients with a plantar forefoot ulcer and diabetes

Journal of Foot and Ankle Research, 2016
BackgroundThe total contact cast (TCC) is an effective intervention to reduce plantar pressure in patients with diabetes and a plantar forefoot ulcer. The walls of the TCC have been indirectly shown to bear approximately 30 % of the plantar load.

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

FEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Modeling of the Loading–Unloading Contact of Two Cylindrical Rough Surfaces with Friction

Applied Sciences, 2020
The first fractal model for the loading−unloading process between two cylindrical surfaces with friction is presented. The nonlinear relation between the real contact area and the contact load in different deformation stages are deduced for a load&#

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Finite-element analysis of contact between elastic self-affine surfaces

, 2004
Finite element methods are used to study non-adhesive, frictionless contact between elastic solids with self-affine surfaces. We find that the total contact area rises linearly with load at small loads.
