Emergence of fractal geometry on the surface of human cervical epithelial cells during progression towards cancer

New Journal of Physics, 2015
Despite considerable advances in understanding the molecular nature of cancer, many biophysical aspects of malignant development are still unclear. Here we study physical alterations of the surface of human cervical epithelial cells during stepwise in ...

Effect of hydrodynamics and surface roughness on the electrochemical behaviour of carbon steel in CSG produced water

, 2015
The influence of fluid flow, surface roughness and immersion time on the electrochemical behaviour of carbon steel in coal seam gas produced water under static and hydrodynamic conditions has been studied. The disc electrode surface morphology before and

Stand-off pad wintering system: Effect of surface types on cow comfort and urination behaviour [PDF]

, 2017
Two consecutive experiments were conducted over four weeks during winter to investigate the effect of different stand-off pad surface types on dairy cow lying behaviour, cleanness and lameness scores, and urination frequency.

Surface core level shift on Be( 112̄0)

, 1994
A photoemission study of the Be(112̄0) surface carried out at a sample temperature of 100 K is reported. A surface shifted Be 1s component, having a shift of - 410 meV, is resolved on this surface.

Squirmer hydrodynamics near a periodic surface topography

Frontiers in Cell and Developmental Biology, 2023
The behaviour of microscopic swimmers has previously been explored near large-scale confining geometries and in the presence of very small-scale surface roughness.

Preliminary Observations of Environmental Effects on Immature Whale Shark Surface Feeding Behaviour in Nosy Be, Madagascar

Diversity
Nosy Be in the northwestern Madagascar hosts one of the largest known seasonal feeding aggregations of whale sharks. However, the environmental drivers influencing whale shark surface feeding behaviour in this area remain poorly understood.

The Influence of Surface Texturing on the Frictional Behaviour of Parallel Sliding Lubricated Surfaces under Conditions of Mixed Lubrication

Lubricants, 2018
In many industrial applications, a modification of the surface geometry can enhance the tribological behaviour of lubricated sliding contacts. In this paper, the effect of surface texturing on the coefficient of friction in parallel sliding lubricated ...

Surface oxidation by laser soft-melting treatment to change degradation behaviour of a magnesium alloy [PDF]

, 2016
The use of Mg and its alloys has been limited in engineering applications due to their low corrosion resistance. On the other hand, since a tuned degradation rate is attractive for biomedical applications, Mg and related alloys are considered a ...

Study of surface discharge behaviour at the oil-pressboard interface

, 2013
This thesis is concerned with the surface discharge behaviour at the oil-pressboard interface. For large transformers this is classified as a serious failure mode because it can lead to catastrophic failure under normal AC voltage operating conditions ...
