Poroviscoelastic Modeling of the Mechanical and Fluid Response of Liver Tissue in Unconfined Compression
… is burst injury, caused by rapidly increasing fluid pressure within this highly vascular organ. Exploration of this type of injury has shown fluid pressure to correlate well to liver injury severity in perfused whole-organ rapid compression testing. This study aimed to address one level of …

An experimental analysis of an impedance pump as a model for segmentation in the intestine
The intestine is a fluid-filled compliant tube that twists, turns, and folds back on itself, potentially causing changes in impedance of the tube. By asymmetrically compressing a compliant tube of physiological geometries with impedance changes, a net pressure head was induced. With Reynolds …

Development, characterization and applications of magnetorheological fluid based "smart" materials on the macro-to-micro scale
Magnetorheological fluids belong to the class of field-responsive fluids that undergo large, reversible and fast changes in their rheological properties when acted upon by an external magnetic field. 'Smart' or controllable composite materials have been obtained by doping polymers, foams, fabrics …

Dis-locations and Broken Narratives: articulating liminal and interstitial experiences through a series of moving image and mixed media installations
… and shape of my work reflecting my personal response to the experience of otherness and dis-location identified as, “The feeling of being between places and people, the sense of transience, the experience of seeing the world and one’s place in it from different perspectives.” 1 This led to …

Mathematical modelling of thixotropic and antithixotropic fluids
… flow in a slowly-varying channel, for complex fluids. Specifically, we investigate these problems for thixotropic and antithixotropic fluids described by Mewis and Wagner's [Advances in Colloid and Interface Science, 147-148, 214-227 (2009)] general structure parameter model together with a …

A variational multiscale framework for non-Newtonian fluid models
… for non-Newtonian models for complex fluids. One class of non-Newtonian fluids is shear-rate dependent fluids that include nonlinear viscosity functions of the second invariant of the rate-of-deformation tensor, thereby resulting in shear-thinning or shear-thickening effects. Another …

Facies-driven, seismic inversion-based property modeling, for flow simulation of Delhi Oil Field, Louisiana
… interpreted in the dip direction S25E. Gassmann fluid substitution evidences a facies-dependent fluid response to oil. The facies dependencies are honored for property modeling of saturation, porosity, and permeability. Seismic inversion for Vp:Vs ratio is used to estimate bulk oil volume. The …

The commercialisation of handicraft production among the Iban of Kapit division in Sarawak, Malaysia : constraints and potential
… linear evolutionary phases; it is a variable and fluid response to changes in the social, economic, cultural and political environment. The study also shows that CI-[P provides the rural Iban with employment and income earning opportunities which, in turn enables them to sustain their livelihood …

Fluid-structure interaction of a cantilevered plate in supersonic separated flow
The study of fluid-structure interaction (FSI) is one of ever-increasing importance as high-speed aircraft continue to reach higher Mach numbers. Research into high-speed FSI is especially critical with respect to control surfaces that may become compliant at these high Mach numbers. In …

Characterization and Molecular Analysis of Fragilysin: The Bacteroides fragilis Toxin
… tissue damage and a subsequent dose dependent fluid response. Histological examination revealed mild necrosis of epithelial cells, crypt elongation, villus attenuation, and hyperplasia. There was extensive detachment and rounding of surface epithelial cells and an infiltration of neutrophils. …

Characterization of Liquid Metal Free Surface Response to an Electromagnetic Impulse and Implications for Future Nuclear Fusion Devices
… The work presented here first characterizes the response of LMs to current pulses which peak between 50 and 200 kA and generate magnetic pressures between 0.5 and 5 MPa. High-speed videography records the liquid metal free surface during and after the current pulse and captures a fast moving, …

Modeling of mechanical energy dissipation of low-dimensional resonators
… or phonons and extrinsic dissipation due to a fluid environment. In this context, low-dimensional resonators need special attention because the dissipation cannot be explained using the existing continuum theories. Due to atomic thickness, sub-micron dimension, and mega- to gigahertz …
