Homologous recombination (HR) permits the precise insertion, deletion, or substitution of genetic material in the genome of an organism. HR offers numerous opportunities for modifying plant genomes to enhance our understanding of plant gene function and regulation, especially with respect to enhancing the production of biofuels. Although HR normally occurs at very low frequencies, approximately ...

Appareo Systems, LLC, proposes to develop a functional prototype head-mounted position and orientation system (HPOS). The HPOS will be capable of operating in electromagnetic fields of up to 200 volts/meter and will provide at least one degree of accuracy and at least one degree of resolution at a 60 Hz update rate while providing 3 degree of freedom (DOF) information on head orientation, includi ...

Hybrid Electric Vehicles (HEVs) and plug-in Hybrid Vehicles (PHEVs) require advanced technology capacitors, which must have low cost and the ability to operate at 150oC. However, current 150oC film capacitor solutions are expensive and have lower energy density compared to materials that operate at lower temperatures. Polypropylene Film Capacitors represent a potentially cost effective solution ...

The objective of the proposed Phase-I research effort is to assess the feasibility of performing high-speed (1-5 kHz) particle-image velocimetry (PIV) and planar laser-induced fluorescence (PLIF) for understanding combustion stability and related phenomena in gas-turbine augmentors. Initial demonstration measurements will be performed in cold and heated air flows using PIV and acetone/biacetyl PL ...

Flow control using high-frequency actuation to reduce acoustic and vibrational loading from weapons bays and sensor apertures requires a diagnostic approach that can capture instantaneous flowfield data at rates of several kHz. Moreover, large wind tunnel facilities suffer the difficulty that particle seeding is problematic for techniques such as Particle Imaging Velocimetry (PIV). The opportuni ...

Historically, remediation efforts at DOE contaminated sites have relied on numerical models to integrate laboratory and field characterization data, predict the fate and transport behavior of contaminant plumes, design remediation protocols to mitigate contaminant migration, and analyze data from field remediation results. Of particular concern is the effect of subsurface heterogeneities and thei ...

Standoff detectors are required to detect IEDs. These detectectors are needed to save the lives of American soldiers. QuantaSpec has developed patent pending methods for long-range, sensitive, and selective standoff detection of explosives. These methods have already demonstrated sensitive remote detection of explosive vapors under previous efforts. QuantaSpec's multidisciplinary team will dem ...

The design of turbomachinery components is a complex process requiring many steps and hundreds of minute decisions in an iterative process. The design proceeds from engine cycle performance and meanline design through 3D viscous flow calculations (CFD) and finite element structural analysis (FEA). Design studies may traverse this process many times, with routine tasks performed by engineers in a ...

Innovative Materials Technologies, Inc. (IMTT) is proposing a Flat Geometry Remote Field & Super Sensitive Eddy Current (FG RFEC & SSEC) technique for the inspection of fastener holes in thick multi-layer structures. Inspection of fastener holes in thick multi-layer structures described in the Topic AF04-134, is a big challenge to all existing or emerging nondestructive inspection (NDI) techniques ...

79671S Attempts to produce Carbon Nano Tube(CNT) in large quantities have been fraught with overwhelming challenges due to poor yield, costly fabrication, and the need for the purifying processes required to make them useful in applications. This project will develop an alternative nanoscale carbon material with comparable properties that can be produced cost-effectively and in larger quantities ...
