51015-98-I High-Voltage, Fast Turn-on and Turn-off Diamond Switch--Alameda Applied Sciences Corp., 2235 Polvorosa Avenue, Suite 230, San Leandro, CA 94577-2249; (510) 483-4156 Dr. Rahul R. Prasad, Principal Investigator Dr. Mahadevan Krishnan, Business Official DOE Grant No. DE-FG03-98ER82524 Amount: $75,000 Improvements in failure rates and reliability of current gas switches used for particl ...

Alameda Applied Sciences Corporation (AASC) proposes to develop two components of a three-component, survivable debris shield for large area test exposures to cold (1-5keV) x-rays. These elements also have commercial potential in accelerators and in radiography. The elements are: an ultrafast gas curtain designed to be located close to the x-ray source to deflect plasma debris as well as ~um siz ...

Alameda Applied Sciences Corporation (AASC) proposes to develop a new type of trigger for a high voltage, high repetition rate diamond switch. AASC has previously developed diamond switches with electron beam triggers. These switches handle 10-20 kV voltage pulses with

The limited availability of donor hearts for people with end stage heart failure has driven the condevelopment of mechanical circulatory support systems (MCSSs). MCSSs can be broadly classified intocontinuous flow systems. Pulsatile systems drive blood indirectly through blood pumps, resulting inThis disadvantage of these systems, however, is their relatively large size. Continuous flow systemssim ...

Minimal access abdominal surgery through the laparoscope has generally replaced surgical procedureslaparotomy for several common procedures, including cholecystectomy and appendectomy. More complicatgastrointestinal operations are also being attempted laparoscopically. Many of these procedures aretechniques which are not yet standard laparoscopic techniques. A basic surgical technique necessarythe ...

Calcification of blood contacting surfaces has been the key impediment to the development of polymevalve prostheses and other polymeric implantables. The deposition of calcium plaques as hydroxyapatiand potentially leads to valve dysfunction. That calcification proceeds preferentially along surfacestress only exacerbates the problem. This work is based on the hypothesis that calcification along fa ...

DSL (Dipole Source Localization) is an important advance in evoked potential research because it prinformation on the location of equivalent dipole generators within the brain, and also separates thesimultaneously-active generators. Since evoked responses are used in both research and in the diagnodisorders, improvements in analysis of evoked responses are very likely to improve their use in mediP ...

This research relates to evoked response testing of humans. The goal is to develop and test a methorecording the middle-latency auditory evoked-potential, to click or tone-pip stimuli at stimulus rep60 Hz, including 40 Hz. This may provide a test of cortical function which is especially sensitive tdeterioration, and which is not presently possible with available technology. It would also permit no ...
