Vapor-liquid equilibria in the system hydrogen-nitrogen-carbon monoxide
Vapor-liquid equilibrium compositions for the system hydrogen-nitrogen-carbon monoxide were determined at -310°F, and -280°F and -240°F from 300 psig to the critical. PVT data for hydrogen were fitted to the ...
Effects of the decay of sulfur-35 on some electrical properties of cadmium sulfide semiconducting films
The vacuum behavior of radioactive and non-radioactive semiconducting films of CdS has been studied as a function of time in order to determine the effect of radioactive doping. Radioactive films containing S35 were made ...
Low temperature vapor-liquid equilibrium in light hydrocarbon mixtures: Methane-ethane-propane system
Experimental equilibrium data have been determined for 175 mixtures of methane, ethane, and propane. The investigation included temperatures from 50°F to -200°F and pressures up to the critical. A vapor recycle ...
A study of alumina silicon fluoride combinations as hydrocarbon conversion catalysts
The purpose of this work was to study the influence of certain variables in the preparation of an alumina-silicon-fluoride complex on its behavior as a cracking catalyst.
Experimental and mathematical analyses of mural thrombogenesis under flow
An epifluorescence video microscopy system, coupled with digital image processing techniques, and a computerized microphotometric measurement system were used to analyze the effects of two antithrombotic agents on surface ...
Videomicroscopy study of behavior of toluene in wet and dry heterogeneous porous media
A novel bead-pack micromodel has been developed to observe directly with videomicroscopy movement and distribution of toluene in the subsurface, including effects of water infiltration, variations in the water table, and ...
Mechanisms of symmetric and asymmetric drainage of foam films
The drainage of horizontal thin liquid films produced from aqueous solutions of ionic surfactants was studied experimentally, using videomicroscopy and interference techniques, for several surfactants in a wide range of ...
A microvisual study of viscosity and mass transfer effects on two-phase flow in porous media
A microvisual flow cell was used to observe the effects of fluid viscosity ratio and of pore size distribution on the mechanisms of steady cocurrent two-phase flow in porous media. The transition in flow mechanisms was ...
Real-time implementation of an intelligent diagnostic and control system for bioreactors
Bioprocesses often require considerable expertise to insure proper operation and performance. However, they are also rich in both data and factual knowledge. Supervision and control can be improved by utilizing information ...
