Effect of propellant morphology on the acoustics of the BATES motor
… results of three-dimensional simulations of the chamber flow within the BATES (Ballistic Test and Evaluation System) 15 pound motor. The injection boundary conditions for the motor are defined by the velocity-temperature temporal correlations. Three different propellant morphologies are modeled …

Effect of potassium level on in vitro magnesium transport across rumen and omasum epithelium of cattle
… from the muscle layer and mounted in parabiotic chambers. The tissues were incubated for 2 h in buffer at 39 C and aerated continuously in 95% O₂ 5% CO₂ . The buffers were similar to those which have been used previously in mineral transport studies, but were modified by varying the levels of Mg …

Feasibility of Echocardiographic Particle Image Velocimetry for evaluation of cardiac left ventricular filling function
… an apparent difficulty to diagnose patients. Flow visualization techniques have been commonly employed to study the development of these diseases as they relate to the filling process of the ventricles. One method, Echo Particle Image Velocimetry (Echo-PIV) is a relatively new method for …

Modelling of turbulent swirling flows
… and reacting anistropic turbulent, swirling flows using popular turbulence models with a robust numrical procedure. The performance of these turbulence models is assessed and compared against experimental data for anisotropic, turbulent swirling flow in a cylindrical pipe and non-reacting and …

TGF-β1-induced Chloride Channel Activity and Migration of Human Eosinophils
… was assessed using a Boyden microchemotaxis chamber. Flow cytometry was used to determine shape change.|The results showed that TGF-β1 stimulation increased protein expression of ClC-3. There was also more CLC-3 protein expression in asthmatic eosinophils than normal eosinophils. TGF-β1 …

Analyses of flame response to acoustic forcing in a rocket combustor
… they affect the operation of the combustion chamber. The cause of combustion instabilities, including which processes are responsible and under what conditions they arise, are not yet fully understood. The ability to predict and prevent combustion instabilities during the design of new …
