THE OBJECTIVE OF THE PHASE II PROJECT IS TO EXPERIMENTALLY DEMONSTRATE THE PERFORMANCE OF SMALL STIRLING CYCLE CRYOCOOLER WITH INNOVATIVE DESIGN AND CONSTRUCTION FEATURES. THE EFFORT ENTAILS DESIGN AND DEVELOPMENT OF COMPONENTS, INTEGRATION INTO AN ENGINEERING MODEL CRYOCOOLER, AND TESTING OF THE CRYOCOOLER FOR PERFORMANCE AND ENDURANCE. ANTICIPATED BENEFITS OF THE INNOVATIVE DESIGN INCLUDE FIVE ...

THE OBJECTIVE OF THIS PROGRAM IS TO DESIGN AND BUILD A STAPLER FOR PERFORMING END-TO-END AND END-TO-SIDE ANASTOMOSES ON MEDIUM TO LARGE VESSELS, AND FOR REPAIRING BLOOD VESSELS AND VASCULAR ANEURYSMS, AND TO DEVELOP A SURGICAL PROTOCOL FOR ITS USE. THE METHOD PROPOSED USES A SPECIAL STAPLER AND CONFIGURATION OF STAPLES WHICH MINIMIZESBLOOD CONTACT WITH THE STAPLES, DOES NOT RESTRICT THE FLOW OF BL ...

The use of dedicated pulsatile ventricular support devices (VAD) for circulatory support is becoming an accepted treatment modality for adult patients requiring support due to post-cardiotomy pump failure or post-AMI cariogenic shock; the VAD could also be used as a bridge to transplant. Although temporary circulatory support in pediatric patients is being performed with ECMO or centrifugal pumps, ...

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 ...

THE PROPOSED WORK INVOLVES APPLICATION OF SUPPORTED MOLTEN SALT CATALYSIS TO THE CATALYTIC ENDOTHERMIC DEHYDROGENATION OF HIGH ENERGY-DENSITY AVIATION FUELS. THE CATALYSTS OF INTEREST ARE HETEROGENEOUSLY DISPERSED PLATINUM AND NICKEL, TO BE USED ALONE OR IN BIMETALLIC CLUSTERS. THE MOLTEN SALTS TO BE USED INCLUDE BINARY AND TERNARY EUTECTICS INVOLVING ALKALI METAL CHLORIDES AND HYDROXIDES. THE SUP ...
