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 ...

We propose to use physiological sensors to measure the quality of a trainee's interaction with a virtual environment (VE) as a function of VE fidelity to enable design improvements in VEs and to enhance training effectiveness through feedback of physiological-based performance information. Currently, VE design is guided by subjective design models that involve multiple design iterations and focus ...

DESCRIPTION (provided by applicant): A collaborative effort between ASL Analytical, Inc. and a research team at the University of Iowa is proposed to development a noninvasive nocturnal hypoglycemic alarm. The goal for the alarm system is to provide continuous noninvasive measurements during the sleep period of an individual with diabetes, sounding an audible alarm to wake the person if an impe ...

Consumers and an ever growing segment of the pork industry know that more optimal levels of marbling must be put back into the high-value pork cuts. Biotronics, Inc. is developing technology to solve this problem by using real-time ultrasound to measure the percent of intramuscular (% IMF) fat in live pigs and hot carcasses. The premise of the project is that swine breeders can be rewarded financi ...

Today's information warriors are not sufficiently trained to deal effectively with the threats posed by our potential enemies and terrorists to disrupt or destroy our computer networks, or steal or delete our valuable and sensitive information stored in these networks. Team DigiFlight has personnel who are skilled in the required technologies, and can develop training scenarios that will be usefu ...

The proposed development will result in a compact, efficient, broadband transducer module including amplifier and wet-end transducer. To facilitate multiple mission requirements, the transducer performance goals are a broad bandwidth (7-30 kHz), compact size on the order of 1/2 wavelength at the center frequency, at least 30 watts output power, and high efficiency. The resulting technology from ...

Current ASW missions require low frequency off-board sound sources that can operate monostatically or bistatically. Since these sources may or may not be recoverable, and may require a substantial number to cover the designated operating areas, the low frequency source transducers also need to be low cost. The team of Etrema Products and Applied Research Laboratory at The Pennsylvania State Univ ...

The size of conventional split ring transducers is much smaller than a wavelength at operating frequency leading to a high Q resonance and limited operating bandwidth. The proposed work will investigate two different modifications to the split ring structure that allow its resonance frequency to be adjusted under active control so that it is always operated at or near its resonance. Because the ...

"This proposal, lead by Frontline BioEnergy, teams with the Iowa State University (ISU), Center for Sustainable Energy Technologies (CSET) to develop high quality, time-stable and storable fast pyrolysis oils in phase-I that are useful for production of fungible liquid fuels such as diesel, gasoline and jet fuel. Our approach uses novel filtration techniques to reduce total alkali contamination in ...
