A series of centrifuge liquefaction tests have been conducted at C-CORE’s geotechnical centrifuge facility: two on variable soil and one on uniform soil deposits. A single storied frame structure resting on two strip footings was also placed on that soil deposit. Experimental results such as accelerations, excess pore water pressures (EPWP) and settlements were monitored throughout the tests. R...

This article gives a historical and technical review of the U.S. gas centrifuge efforts between 1934 and 1985. The first section tells of how the United States initially led in centrifuge design, only to abandon the still-immature technology in the midst of the Manhattan Project. While interest in the technology continued in Europe, the United States decided that centrifuges were not a viable a...

Ultracentrifugation for determination of isotropic concentrations of fatty acids is widely used. However, several artifacts, which would affect the isotropic concentration, could occur if care is not taken. These include sedimentation of micelles, incomplete flotation of unsolubilized oil, and uptake of labeled fatty acid by the walls of centrifuge tubes. The first artifact can be overcome by s...

In the first part of this thesis the means are described by which an industrial disc stack centrifuge may be scaled-down to process in a meaningful fashion small volumes of particle suspensions. The centrifuge separation characteristics so measured were suitable for direct scale-up predictions of centrifuge performance. Experiments with a dye tracer and a reduced number of discs indicated that ...
