Investigation of viscosity effects on bacteria collective motion using particle image velocimetry
… research has investigated how contrasts in fluid viscosity would influence the collective motion of swimming bacteria. In this paper, Particle Image Velocimetry (PIV), a commonly-used method to measure nonintrusive, instantaneous and whole-field velocity, is applied to visualize the swimming …

High Pressure Study of Viscosity Effects on the Luminescence of Some S-Tetracyanobenzene Eda Complexes
… (TMPD), and a mixture of MCH and HMN. A viscosity range from 0.006 to 10,000 poise was covered at two temperatures, 0(DEGREES)C and 25(DEGREES)C. As pressure (viscosity) increased the fluorescence spectrum shifted from one dominated by emission from the equilibrium (EQ) excited singlet …

Numerical Simulation of Leading Edge Vortex Rollup and Bursting
… study vortex flows, they don't include physical viscosity effects associated with vortex flows. The Euler solvers do, however, contain numerical viscosity. As a result, viscosity effects in the Euler solutions such as vortex core size, vortex burst location, leading edge separation, and vortex …

SIMULATION OF POLLUTANT TRANSPORT RESPONSES TO LOADING AND WEATHER VARIATIONS IN LAKE ST. CLAIR AND THE CONNECTING CHANNELS.
… and contaminants. In an attempt to include the effects of the seasonal variations on the circulation patterns in Lake St. Clair, a three dimensional finite element model which includes wind stress, bottom friction, Coriolis force, inflow, outflow and the bottom topography of the lake was …

Experimental and predicted performance for the combustion of a low heating value gas in a swirl burner
… The PRIMCO code includes variable density and viscosity effects and incorporates a two-equation turbulence model for the Reynolds stress terms. The PRIMCO code also uses a simplified, infinite reaction-rate combustion model. Because of the use of the non-staggered grid system, the CENCIS …

Impact of ingredient interactions on the physico-chemical stability of milk protein-stabilised oil-in-water emulsions
… creaming may occur due to depletion flocculation effects when adding a neutral polysaccharide to these protein-stabilised emulsions. This macroscopic demixing could be reduced by formation of a sufficiently strong three-dimensional network, which could be realised by further increasing the guar …

Three Problems Involving Compressible Flow with Large Bulk Viscosity and Non-Convex Equations of State
… fluids. In each problem non-classical effects are considered. In the first two problems, we consider fluids which have bulk viscosities which are much larger than their shear viscosities. In the last problem, we examine steady supersonic flows of a Bethe-Zel'dovich-Thompson (BZT) fluid …

Air Ingress and Heat-Driven Flow Relaminarization in a Very High Temperature Reactor (VHTR)
… heat transfer data along with the density and viscosity effects are analyzed to identify possible changes in heat transfer rates from the graphite to the coolant in the riser.</p> <p>The second phenomenon studied is the issue of heat-driven flow relaminarization (forced convection), in which a …

In search of catalytic proficiency: The importance of enzyme conformational change to orotidine 5’-monophosphate decarboxylase catalysis
… of the kinetic parameters for various OMPDCs on viscosity (2). This allowed me to determine to what degree chemistry was important to the measured rate because changing viscosity affects the rate of physical steps outside of the active-site while leaving unchanged the chemical steps secluded from …

Acoustic-Gravity Wave Propagation Based on Solutions to the Generalized Multi-component Transport Equations
… with fixed composition; these time-dependent effects have been included in a one-gas model by adding an advection equation for the molecular weight, finding closer agreement to a true binary-gas model (e.g. Walterscheid [2012]). Here, we solve the hydrodynamic conservation equations for a …

The Role of Branching Topology on Rheological Properties and its Effect on Film-Casting Performance
… of film necking are also made to separate the effects of molecular weight distribution, MWD, and LCB. The results indicate that both broadening the MWD and the addition of sparse LCB reduce the degree of necking observed. It is established that film necking is more significantly reduced by LCB …

STRUCTURE-FUNCTION STUDIES OF NOVEL MEDICALLY RELEVANT FLAVOENZYMES
… binding is governed by electrostatics. Solvent viscosity effects revealed the presence of conformational changes taking place during the catalytic cycle, another property shared with enzymes of the PHBH family that avoid waste of reducing power and release of reactive oxygen species through …
