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 ...

Multiscale study of the dynamic friction coefficient due to asperity plowing
, 2020 A macroscopically nominal flat surface is rough at the nanoscale level and consists of nanoasperities. Therefore, the frictional properties of the macroscale-level rough surface are determined by the mechanical behaviors of nanoasperity contact pairs ...

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 ...

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank
FEBS Open Bio, EarlyView.Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

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

FEBS Open Bio, EarlyView.In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...
