Northern anchovy (Engraulis mordax) are a dominant forage fish in the California Current large marine ecosystem (CCLME). However, little is known about northern anchovy abundance, distribution, age structure, or population fluctuations relative to ocean conditions in the eastern boundary upwelling system off the U.S. West Coast. This thesis includes three...

Polycyclic aromatic hydrocarbons (PAHs) are carcinogenic chemical compounds found in the
environment, largely as a result of partial combustion of organic compounds. PAHs are
present in the atmosphere in populated cities worldwide. Because of the health risks they
create, PAHs are a global health concern. PAHs are introduced into the...

Eighty three northern fur seals were collected in the summer and fall of 1981, 1982, and 1985 for examination of gastrointestinal contents. A total of 139...
Purpose: Stereotactic radiation therapy and stereotactic radiosurgery deliver radiation precisely to tumors, using special equipment to position and demobilize patients. The VisionRT system, with its component AlignRT, is a non-invasive stereotactic positioning and tracking system that uses cameras to capture infra-red images of patients, and process these images, to obtain...
