The radioactive carbon used in these studies was carbon-11, abbreviated as which was prepared by bombarding boric oxide in the 70 centimeter cyclotron. Carbon-11 has a half life of twenty minutes, which means that one half of it remains after twenty minutes, one quarter remains after forty minutes, one eighth remains after one hour, one part in sixty four remains after two hours. An experiment using carbon-11 needs to be completed within a small number of hours. A book by Martin D. Kamen Radiant Science, Dark Politics, A Memoir of the Nuclear A e, University of California Press, Berkeley and Los Angeles, California, 1985] gives this account of working in the laboratory with the fast decaying carbon-11. 

As seen in Table 17.4.1, box model (single cell) simulations designed to represent summertime conditions in Los Angeles, California indicate that the amount of carbon associated with each class of compound only roughly corresponds to the amount of ozone formed from those compounds. Methane, which reacts very slowly but eomprises most of the carbon, contributes little to ozone formation. Alkenes and aromatics are only a small part of the total carbon, but lead to much of the ozone formation. 

Data on the performance of panels of granular coconut-shell activated carbon treating air in six buildings in the Los Angeles. California, area are given by Bayati and Graham (1991). 

We used the measurements of organic carbon and uranium in a sea core, made by Paul R. Doose, Emil K. Kalil, and I. R. Kaplan of the University of California at Los Angeles, and we compared our stable isotope measurements with Hans Suess measurements of radiocarbon in the bristlecone pine ring sequence prepared by Wesley Fergusson, (see fig. 27), Suess at the University of California at San Diego, and Fergusson at the University of Arizona, Tucson.

Researchers at the University of Southern California, Los Angeles, have developed a technology called the hybrid microfiltration-bioactive carbon (MF-BACP) process, for the ex situ treatment of contaminated groundwater. 

A six-inch carbon steel elbow in a Los Angeles refinery ruptured releasing a hydrocar-bon/hydrogen mixture at 9 43 P.M. on October 8, 1992. The vapor cloud ignited within seconds. The explosion damaged nearby buildings and shattered windows several miles away and was recorded as a sonic boom at the California Institute of Technology about 20 miles away. [21]...

In a second example, we consider the changing chemistry of Mono Lake, a saline alkaline lake that occupies a closed desert basin in California, USA, and why gaylussite [CaNa2(CO3)2-5H2O], a rare hydrated carbonate mineral, has begun to form there. The lake has shrunk dramatically since 1941, when the Los Angeles Department of Water and Power began to divert tributary streams to supply water for southern California.
