United States earthquakes, 1975

Abstract

Among the commercial agencies on the west coast rendering valuable services are telephone, power, oil, railroad, and especially insurance companies. Certain concerns interested in the manufacture of earthquake-resistant building materials are also active together with various organizations of structural engineers and architects. In other parts of the country the Jesuit Seismological Association with central office at St. Louis University collects information in the central Mississippi Valley area (Rev. Dr. James B. Macelwane, S. J., Dean of the Institute of Technology). The Northeastern Seismological Association with headquarters at Weston College, Weston, Mass. (Rev. Daniel J. Linehan, S. J., in charge), undertakes similar work in the northeastern States. Modified Mercalli Intensity Scale of 1931 .All intensities used by the Coast and Geodetic Survey refer to the Modified Mercalli Intensity Scale of 1931.' The abridged version of this scale is given here with equivalent intensities according to the Rossi-Forel scale.

Historical perspective on seismic hazard to Hispaniola and the northeast Caribbean region

“…DYFI questionnaires were designed to match the descriptions of MMI intensities and are assumed to be equivalent (D. Wald, written communication, 2011). Damage reports from events before 2000 were compiled from different sources [ Bodle and Murphy , 1984; Coffman and von Hake , 1984a; Coffman and Stover , 1984; Coffman and von Hake , 1984b; Stover and Brewer , 1991]. The number of locations of intensity reports for these calibration events varies from 3 to 55.…”

Future of antibody purification

“…Additionally, a unit operation used in microbial recovery operations, flocculation, has been used to reduce or eliminate the need for depth filtration downstream of the centrifuge [18]. These act to increase the amount of cellular debris being removed by the centrifuge, thereby improving the clarity of the harvested cell culture fluid, and requiring little or no depth filtration prior to the capture step.…”

“…Other efforts to reduce or eliminate the need for depth filtration downstream of the centrifuge include the use of flocculating agents in the cell culture fluid. These act to increase the amount of cellular debris being removed by the centrifuge, thereby improving the clarity of the harvested cell culture fluid, and requiring little or no depth filtration prior to the capture step [18]. Improvements in centrifugation technology, including the use of hermetic inlets to reduce cell shear, have been crucial for widespread adoption of this unit operation.…”
