Friction Coefficient of a Ladyfinger Banana Peel

International Scholastic Journal of Science, 2020
The coefficient of static friction of a lady finger banana peel was investigated for varying values of vertical compression force. The peel was placed on a tile surface, with a person placing her Converse sneaker on the peel and pushing down with force ...

Friction Coefficient Compensation Control in Synchronizer Synchronization Process for Transmission

Applied Sciences, 2019
In the synchronization process of a synchronizer, the friction coefficient of the friction cone is changed because of friction heat. In this paper, the influence of a changing friction coefficient on shift quality was analyzed.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Friction dependence of shallow granular flows from discrete particle simulations [PDF]

, 2011
A shallow-layer model for granular flows is completed with a closure relation for the macroscopic bed friction or basal roughness obtained from micro-scale discrete particle simulations of steady flows. We systematically vary the bed friction by changing

Phenomenological contact line friction coefficient

Droplet
An important feature of contact line motion, as an irreversible process, is its dissipative nature, which can dominate the dynamics during the early stages of droplet spreading.

Study of Effect of Metal Oleates on Mixed and Boundary Lubrication

Tribology in Industry, 2020
The article presents the results of a study of metal oleates for friction with mixed and boundary lubrication. The objects of study are copper (II), zinc (II), and tin (II) oleates. The boundary friction coefficient in a "steel - steel" friction pair was
