Tissue water and mechanical property changes accompany lymphedema, however the relationship between these changes, if any, is unclear. Local tissue water is quantifiable using the tissue's dielectric constant (TDC), but a non-gravity dependent handheld clinical assessment tool to easily quantify corresponding local tissue properties is not widely available. Herein such a tool is described along...

A small laboratory fermentor which employs mechanical agitation for the dispersion of air introduced under pressure has previously been described by Feustel and Humfeld (1946). This fermentor has an operating capacity of 500 to 2,000 ml and has been found very useful for small-scale, yeast-culturing investigations, as well as for studies on the production of subtilin activity by Bacillus subtil...

We present a sharp-interface algorithm for simulating the diffusion-driven bubble growth in polymer foaming. A moving mesh of unstructured triangular elements tracks the expanding and deforming bubble surface. In the interior of the liquid, the mesh velocity is determined by solving a Laplace equation to ensure spatially smooth mesh movement. When mesh distortion becomes severe, remeshing and i...

foam injection is becoming a standard conditioning agent when tunnelling with an earth-pressure balanced shield, resulting in an increasing interest in this technique. the technique is mostly based on empirical rules and experience. to be able to determine what foam and how may foam has to be injected for different soils, it is necessary to know the mechanical parameters of the foam-water-soil ...

Consider a homogenized spectral pencil of exactly solvable linear differential operators Tλ = Pk i=0 Qi(z)λ k−i d i dzi , where each Qi(z) is a polynomial of degree at most i and λ is the spectral parameter. We show that under mild nondegeneracy assumptions for all sufficiently large positive integers n there exist exactly k distinct values λn,j , 1 ≤ j ≤ k, of the spectral parameter λ such tha...

We present a dynamic network model to investigate the effects of capillary number and viscosity ratio on displacement patterns and fractional flow in primary drainage. This model predicts the events that are observed in the micro-model experiments, such as swelling of the wetting layers and the meniscus oscillation. Interfaces are tracked through the pore elements using a modified Poiseuille eq...
