IN RECENT YEARS, CONSIDERABLE ATTENTION HAS BEEN FOCUSED ON THE DEVELOPMENT OF TECHNIQUES FOR GENETIC TRANSFORMATION OF HIGHER PLANTS. MOST ADVANCES HAVE BEEN MADE USING EITHER PETUNIA OR NICOTIANA AS A MODEL EXPERIMENTAL SYSTEM, MAINLY BECAUSE THESE PLANTS RESPOND WELL FOR REGENERATION IN CELL CULTURE. THERE IS AN OBVIOUS NEED TO EXTEND THESE STUDIES TO OTHER SPECIES, FOREST TREES IN PARTICULAR, ...

Over the past few decades, computational electromagnetics (CEM) researchers have been making steady progress towards the development of efficient algorithms, such as the Method of Moments (MoM), for simulating scattering from electrically large targets. Unfortunately, such techniques have proved too computationally demanding because they require the solution of an often very large and dense matri ...

DESCRIPTION (provided by applicant): The overall goal of this research is the development of a diagnostic methodology for predicting whether treatment of atherosclerotic stenoses in the renal artery will provide sufficient benefit in controlling hypertension or maintaining renal function to offset the risks of the treatment. Stenoses in the renal artery are comparatively common, yet prior studies ...

Natural gas provides a clean and environmentally friendly fuel for electric power generation; however, the distribution network, and especially the storage system, is ill-suited for the projected gowth of natural gas for use in electical energy generation. This project will develop a natural gas (methane) storage system based on an innovative, high-bulk-density activated carbon that is especially ...

We propose to develop a novel thermal interface material (TIM) that is based on an array of vertical carbon nanotubes (CNTs) for high heat flux applications. For high precision, spaceborne lasers and other high power devices critical to NASA's Science Mission Directorate, heat flux levels are projected to reach 100 W/cm2. The state-of-the-art in space-compatible thermal interface materials (TIMs ...

THE ULTIMATE HIGH-EFFICIENCY CRYSTALLINE SILICON SOLAR CELL DESIGN CONSISTS OF A THIN FILM OF ELECTRICALLY-ACTIVE SILICON EPITAXIALLY GROWN ON AN OXIDE-OVERCOATED, INFRARED-TRANSPARENT GALLIUM PHOSPHIDE (GAP) SUBSTRATE. IN ADDITION TO HIGH CONVERSION EFFICIENCY AND INTRINSIC RADIATION RESISTANCE DUE TO THE THIN ACTIVE LAYERS, THIS NOVEL DESIGN HAS SEVERAL UNIQUE PERFORMANCE ENHANCING FEATURES. THE ...

DESCRIPTION (provided by applicant): Historically blood oxygenator technology either for short-term by-pass surgery or recently developed long-term strategies has been mass transfer limited by liquid side mass transfer fluid dynamics. Recent active mixing designs have led to systems which remove liquid side fluid limitations and have oxygen and carbon dioxide transport limited by membrane transpo ...

This Phase II SBIR project addresses the need for advanced thermal management technology for cooling solid-state power conversion devices on-board Navy ships. It is anticipated that the drive towards smaller electronic components and faster switching speeds will require a cooling technology that can dissipate in excess of 1,000 W/cm2 while maintaining junction temperatures below 125 C. In Phase ...

DURING THE LAST 25 YEARS THE DENSITY OF COMPUTER ELECTRONIC CIRCUITRY HAS INCREASED BY FIVE ORDERS OF MAGNITUDE. THIS DRIVE TOWARD MORE DENSELY PACKAGED MICROELECTRONICS HAS RESULTED IN A DRAMATIC INCREASE IN THE AMOUNT OF WASTE HEAT WHICH MUST BE DISSIPATED. HEAT FLUX RATES IN CURRENT LSI CIRCUITRY ARE ALREADY AS HIGH AS 20 W/CM2 AND PROJECTED LEVELS FOR VLSI AND FUTURE ADVANCED CIRCUITRY CONFIGU ...
