EFFECT OF TIP RADIUS OF THE INDENTERS ON FRICTION COEFFICIENT OF THE SCRATCHED METALLIC SHEETS [PDF]

Journal of the Egyptian Society of Tribology, 2013
The objective of the present work is to perform a scratch test to measure the abrasion wear resistance of metallic sheets. Besides, the deformation modes and the friction processes involved during the scratching will be investigated in order to get a ...

Experimental investigation of the frictional behavior of single glass fiber filament

Journal of Engineered Fibers and Fabrics, 2023
Fiber friction behaviors are crucial for understanding the ubiquitous frictional damage phenomena in the manufacturing and service processes of multiscale textile reinforcements. This paper investigates the influence of relative velocity and applied load

Efficiency of polymer materials in highly loaded systems in the aviation industry

Aviation, 2023
The static coefficient of friction was calculated on an inclined plane tribological stand. Different specimens and masses loading the system were used during the experiment. Surface-to-surface contact was tested in a pin-on-plate setup.

Lubricity of carbon nitride coatings in humid nitrogen gas environment

Nihon Kikai Gakkai ronbunshu, 2014
In this study, friction coefficient of 0.018 in averaged value could be achieved under humid nitrogen gas condition (0.5-40 %RH) with frictional pair of amorphous carbon nitride (CNX) coatings. The coatings investigated were deposited onto Si3N4 ball and

FRICTIONAL BEHAVIOUR OF BARE FOOT AND RUBBER FOOTWEAR SOLE SLIDING AGAINST POLYPROPYLENE BRAKE PEDAL PADS [PDF]

Journal of the Egyptian Society of Tribology, 2011
The present work discusses the friction coefficient displayed by bare foot and footwear soles sliding against polypropylene brake pedal pads. The frictional performance is compared to that obtained from the rubber conventional pads.

Interpreting the effects of DNA polymerase variants at the structural level

Molecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

FEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Estimation for Runway Friction Coefficient Based on Multi-Sensor Information Fusion and Model Correlation

Sensors, 2020
Friction is a crucial factor affecting air accident occurrence on landing or taking off. Tire–runway friction directly contributes to aircraft stability on land. Therefore, an accurate friction estimation is a rising issue for all stakeholders.

EFFECT OF MAGNETIC FIELD ON THE PERFORMANCE OF VEGETABLES OILS DISPERSED BY POLYMERIC PARTICLES [PDF]

Journal of the Egyptian Society of Tribology, 2011
The present work discusses the effect of magnetic field on the performance of vegetables oils dispersed by polymeric particles. Experiments were carried out using castor, olive, corn, almonds, jasmine and camomile. Fine particles of polyethylene (PE) and
