GLOMERULAR NUMBER AND CAPILLARY DIMENSIONS IN THE NORMAL LAMB KIDNEY

open access: yesImage Analysis and Stereology, 2011
Reduced nephron endowment, either inherited or acquired, has been linked to adult renal pathology as well as hypertension. The sheep provides an excellent model for studying nephrogenesis and renal development because, as in humans, nephrogenesis is ...

The number of capillary bridges in a wet granular medium

open access: yes, 2003
We observed the appearance of capillary bridges in a granular medium consisting of glass beads after adding small amounts of liquid. We found the initial bridge formation depending on the bead roughness. Furthermore we obtained a statistics for the average number of bridges for randomly packed beads in dependence of the liquid content and were able to ...

Review on the development of truly portable and in-situ capillary electrophoresis systems

open access: yes, 2013
Capillary electrophoresis (CE) is a technique which uses an electric field to separate a mixed sample into its constituents. Portable CE systems enable this powerful analysis technique to be used in the field.

Rheology of High-Capillary Number Two-Phase Flow in Porous Media

open access: yesFrontiers in Physics, 2019
Flow of immiscible fluids in porous media at high capillary numbers may be characterized by an effective viscosity. We demonstrate that the effective viscosity is well-described by the Lichtenecker-Rother equation.

Characterization of Porosity and Copper Infiltration Mechanism in Sintered Steel via Computed Tomography

open access: yesMetals
This study employs CT non-destructive detection to quantitatively analyze the pore structure of sintered steel and investigate copper infiltration mechanisms. As density increases from 6.55 to 6.95 g/cm3, pore characteristics exhibit significant changes:

Mathematical modeling of the magnetic field in the vicinity of narrow capillaries [PDF]

open access: yesE3S Web of Conferences
A mathematical model of the magnetic field, which is generated by negative charges located on the outer side of the red blood cell (RBC) membrane, has been constructed.

Hydrodynamic structures of droplets in square micro-channels [PDF]

open access: yes, 2008
This paper reports on numerical simulations of the hydrodynamics inside droplets in rectangular micro-channels. We use a finite-volume/front-capturing method that allows us to perform two- and three-dimensional simulations with a reasonable cost.

Oscillation of a Liquid Column in an Eccentric Annulus

open access: yesFluids
The velocity distribution of flow in an eccentric cylindrical annulus is determined in an attempt to investigate the vertical capillary rise in the channel.

IMPACT OF CAPILLARY AND BOND NUMBERS ON RELATIVE PERMEABILITY

open access: yes, 2002
Recovery and recovery rate of oil, gas and condensates depend crucially on their relative permeability. Relative permeability in turn depends on the pore structure, wettability and flooding conditions, which can be represented by a set of dimensionless groups including capillary and bond numbers.
