Sediment Removal From The San Gabriel Mountains, Mary C. Ferguson May 2012

Sediment Removal From The San Gabriel Mountains, Mary C. Ferguson

Pitzer Senior Theses

The issue of sediment removal from the San Gabriel Mountains has been a complex issue that has created problems with beach replenishment, habitat destruction and the need to spend millions of dollars at regular intervals to avoid safety hazards. Most recently 11 acres of riparian habitat, including 179 oaks and 70 sycamores, were removed for sediment placement. Other sites including Hahamongna Watershed Park and La Tuna Canyon also face a similar fate. This thesis questions: How did we get to this point of destroying habitat to dump sediment which is viewed as waste product? What are the barriers for creating …


Rapid, Large-Scale Production Of Full-Length, Human-Like Monoclonal Antibodies, Christopher M. Warner Jan 2012

Rapid, Large-Scale Production Of Full-Length, Human-Like Monoclonal Antibodies, Christopher M. Warner

KGI Theses and Dissertations

Current recombinant protein production systems require several months to develop. Existing systems fail to provide timely, flexible, and cost-effective therapies to protect against emergency mass-casualty infections or poisonings. As the identity of many new biological threat agents are unlikely to be known in advance, pre-emptive manufacturing and stockpiling of countermeasures cannot be performed. Preparedness for a biological catastrophe requires a radical solution to replace the current slow scale-up and manufacture of lifesaving medical countermeasures. Subunit vaccines and antibody fragments may be produced in bacteria, yeast, plant or insect cells. However, generation of full-length, human like glycosylated antibodies requires mammalian cell …


Wireless Channel Equalization In Digital Communication Systems, Sammuel Jalali Jan 2012

Wireless Channel Equalization In Digital Communication Systems, Sammuel Jalali

CGU Theses & Dissertations

Our modern society has transformed to an information-demanding system, seeking voice, video, and data in quantities that could not be imagined even a decade ago. The mobility of communicators has added more challenges. One of the new challenges is to conceive highly reliable and fast communication system unaffected by the problems caused in the multipath fading wireless channels. Our quest is to remove one of the obstacles in the way of achieving ultimately fast and reliable wireless digital communication, namely Inter-Symbol Interference (ISI), the intensity of which makes the channel noise inconsequential.

The theoretical background for wireless channels modeling and …
