This work studies numerically the generation mechanism of a new type unburnt gas pocket and its effects on characteristics detonation-wave/boundary-layer interaction in supersonic flows. Results show that this is generated due to local re-ignition preheated behind separated oblique shocks, unlike traditional pockets longitudinal instability detonation front. The chemical energy released by area...

A 70-year-old man presented to the Emergency Department with lower abdominal pain, abdominal distention and fever of 3 days duration associated with increased urinary frequency, urgency and pneumaturia. He was known case of type 2 diabetes mellitus on oral anti-diabetic agents for the past 15 years. On Physical examination, he had a temperature of 38, 8°C and a diffuse abdominal tenderness with...

Simultaneous planar laser-induced incandescence, hydroxyl radical planar laser-induced fluorescence, and droplet Mie scattering are used to study the instantaneous flame structure and soot formation process in an atmospheric pressure, swirl-stabilized, liquid-fueled, model gas-turbine combustor. Optimal excitation and detection schemes to maximize single-shot signals and avoid interferences fro...

Endorectal balloons (ERBs) are routinely used in prostate proton radiation therapy to immobilize the prostate and spare the rectal wall. Rectal gas can distend the rectum and displace the prostate even in the presence of ERBs. The purpose of this work was to quantify the effects an ERB with a passive gas release conduit had on the incidence of rectal gas. Fifteen patients who were treated with ...

The dynamics of two-dimensional fluids confined within a random matrix of obstacles is investigated using both colloidal model experiments and molecular dynamics simulations. By varying fluid and matrix area fractions in the experiment, we find delocalized tracer particle dynamics at small matrix area fractions and localized motion of the tracers at high matrix area fractions. In the delocalize...

Coincidence of the properties of ligand binding pockets in native proteins with those in proteins generated by computer simulations without selection for function shows that pockets are a generic protein feature and the number of distinct pockets is small. Similar pockets occur in unrelated protein structures, an observation successfully employed in pocket-based virtual ligand screening. The sm...
