Laboratory experiments on warm fog dissipation.
… utilized during these small-scale fog chamber experiments were limited to the use of hygroscopic materials, surfactants and ethyl alcohol. Results indicated that those hygroscopic agents tested, such as NaCl and glycerin, proved to be relatively effective warm fog dispersants compared to …

Laboratory Experiments Investigating Entrainment By Debris Flows
… stresses and particle-scale interactions using laboratory experiments in an instrumented experimental laboratory debris flow flume. Using a high-speed camera, we monitor volume fractions, flow velocities, and instantaneous entrainment and deposition. Our measurements of total erosion support …

Using Laboratory Experiments to Better Understand Voluntary Contributions
… time or money. We test this assumption in a laboratory (and other related phenomena concerning giving time and money to charity). Further, we test how individuals react to third-party information regarding charities. This is to help understand what impact, if any, a group's (e.g., Charity …

Microcomputer-based Laboratory Experiments Involving Motion and Force
… in science education is in a microcomputer-based laboratory. In this type of laboratory, the microcomputer is used as a data gathering and data analyzing instrument. Laboratory data collecting devices, such as photogates and temperature transducer probes, are interfaced with the microcomputer. The …

Using laboratory experiments to study otherwise unobservable labor market interactions
<p>In this dissertation, we use laboratory experiments to study otherwise unobservable interactions in the labor market. The key advantage of laboratory experiments is the ability to control conditions more tightly than in any other context, so it plays a distinctive role in serving as the first …

Laboratory experiments of multi-phase plumes in stratification and crossflow
… sources ranged from 3 to 35 cm/s. Stratified experiments investigated the dependence of plume properties on the nondimensional slip velocity, UN= us/(BN)1/4 , where u, is the slip velocity, B is the total kinematic buoyancy flux, and N is the Brunt-Vaissld buoyancy frequency. First, UN …

Slip on ridge transform faults : insights from earthquakes and laboratory experiments
… are related to the RTF tectonic parameters. Laboratory work on the frictional stability of olivine aggregates shows that the depth extent of oceanic faulting is thermally controlled and limited by the 600°C isotherm. Slip on RTFs is primarily aseismic, only 15% of the tectonic offset is …

Investigating Bisulfide Sorption onto Bentonite through Laboratory Experiments and Numerical Modelling
… process onto bentonite through extensive laboratory experiments and numerical modelling. First, a robust methodology was developed to build confidence in the experimental procedure. Subsequently, six sets of batch experiments (including desorption tests) were performed as a function of …

Laboratory Experiments of High-Energy-Density Shocks in Magnetized Supersonic Plasma Flows
… pulsed-power driven high-energy-density-plasma laboratory experiments, by generating hypersonic, magnetized large-Reynolds’ number plasma flows, using exploding z-pinch wire arrays on the MAGPIE facility (1.4 MA peak current, 250 ns rise time). Plasma flows from adjacent wire cores expand and …

Chaotic advection and mixing in a western boundary current-recirculation system : laboratory experiments
… in a 'sliced-cylinder' rotating tank laboratory experiment. Two flow configurations are investigated: a single recirculation and a double, figure-8, recirculation. The latter case involves a hyperbolic point, while the former does not. I investigate the stirring and mixing under both …

Hazards presented by pyrolysis and combustion products during laboratory experiments and real incidents
Heat, flame, smoke and fire gases are responsible for the vast majority of fire deaths and injuries and are all products of the chemical and physical processes that occur within fire. This is well known and supported by fire statistics but current fire safety does not directly consider these …
