Tsunami Hazards Associated with the Catalina Fault in Southern California

“…Even though submarine landslides may be triggered by large earthquakes offshore, or on coastal or onshore fault systems like the San Andreas, such as occurred in Monterey Bay during the 1989 Loma Prieta earthquake (Schwing et al 1990, McCarthy et al 1993), large possibly catastrophic submarine landslides appear to be relatively rare offshore southern California. For example, the large basement-involved landslide described by Legg and Kamerling (2003) appears to be more than 100 ka, and the large San Pedro Canyon submarine landslide is about 7,500 years old (Fisher 2002). Large earthquakes, with M W у7 involving slip of 1-6 m would have recurrence times of a few hundred to a few thousand years, substantially shorter than the suspected frequency of large submarine landslides in the borderland.…”

Immunoassay of Endogenous Plasma Insulin in Man

“…Two preparations of human insulin were employed as standards. The first ("Tietze human insulin")3 is reported (24) to have a potency of 1.8 U per mg crude preparation; the second ("Fisher human insulin"),3 was assayed at 6.8 U per mg in 1956 (25), but it was believed that the activity of the latter preparation might have decreased slightly since its initial preparation (25). A tentative value of 6 U per mg for the Fisher insulin was assigned.…”

“…A tentative value of 6 U per mg for the Fisher insulin was assigned. However, since a value as low as 22 U per mg could be placed on a crystalline sample of the latter preparation (25), whereas the Tietze insulin was assayed relative to a standard of 27 to 29 U per mg, we have regarded the Tietze crude insulin preparation as 1.8/28 X 100 = 6.45 per cent pure insulin by weight, and the Fisher insulin powder preparation as 6/22 X 100 = 28.2 per cent pure insulin by weight. When compared on this basis, no consistent differences in potencies of the two preparations were observed in the immunoassay procedure and the value of 6 U per mg for the Fisher preparation was accepted as the correct value.…”

Autogenous regulation of the Bacillus subtilis glnRA operon

“…GlnR alone is not sufficient to regulate the glnRA operon in vivo in response to the nitrogen source. Genetic experiments have shown that GS is also required for proper regulation of glnRA (3,8,21,23,29) and other nitrogen metabolism operons (1,5,14). The effects of glnA mutations do not appear to be due to any decrease in the intracellular glutamine pool (7).…”
