Award Data

High-resolution scintillation crystals and crystal arrays are important components of current and future handheld and arrayed detectors (used for DOD/DTRA applications), and scintillation spectrometers (routinely used in high energy physics research, medical imaging, diffraction, homeland security, nuclear waste clean-up, nuclear treaty verification and safeguards, and geological exploration). Un ...

A batteryless and wireless sensor for intrusion detection and assessment of threats which requires no battery, external power or wiring is proposed. These types of sensors derive energy from passing vehicles or persons, and indicate their presence, location, speed, etc., via a self-generated short-range radio signal. These sensors require no maintenance, and can be inconspicuously placed in window ...

Key factors determining reproductive efficiency are control of estrus and ovulation in weaned sows and in gilts, which have already begun to display estrous cycles. Weaning sows at 3 weeks or greater of lactation results in a high percentage of them displaying estrus 5-8 days later. Feeding the orally active progestin, MATRIX, to gilts for 14 days results in greater than 85% of them displaying est ...

The Phase II effort is to be conducted to complete the development of a new ethylene monitor with a detection limit at or below critical levels for storage of perishable commodities. The research effort will help with the development of a new ethylene monitor for use with control systems to regulate ventilating and/or scrubbing of the atmosphere within storage and transport contains to minimize da ...

GREENHOUSES MUST MEET THE CONFLICTING REQUIREMENTS OF BOTH ADMITTING SUBSTANTIAL AMOUNTS OF SUNLIGHT TO THE ENTIRE GROWING AREA, OF PROVIDING VERY SUBSTANTIAL INSULATION TO REDUCE HEAT LOSS IN WINTER, AND MINIMIZE VENTILATION AND COOLING COSTS. BROAD BANDWIDTH HOLOGRAMS THAT ARE DESIGNED TO REDIRECT THE PORTIONS OF THE SOLAR SPECTRUM REQUIRED FOR PLANT GROWTH CAN BE AN IDEAL SOLUTION FOR ADMITTING ...

THIS PROPOSAL INVESTIGATES AN EXTENDED LINE-OF-SIGHT RADIO TECHNIQUE FOR LOW-COST DATA AND VIDEO LINKING OF RURAL ORGANIZATIONS AND PUBLIC INSTITUTIONS. EFFECTIVE RURAL WIDEBAND COMMUNICATIONS ARE OFTEN HAMPERED BY THE DIFFICULTY OF OBTAINING RIGHT-OF-WAY FOR CABLES AND/OR BY THE COST OF LEASED LINES OR SATELLITE CHANNELS. DIRECT RADIO LINKS WOULD BE ATTRACTIVE DUE TO THEIR NON-INTRUSIVE NATURE, P ...

THE PROPOSED PROGRAM WOULD RESULT IN THE DEVELOPMENT OF A PORTABLE FIELD INSTRUMENT FOR THE MEASUREMENT OF AMBIENT AIR TEMPERATURE TO AN ABSOLUTE ACCURACY OF 0.01 DEGREES CENTIGRADE. THE PROPOSED INSTRUMENT WOULD SUBSTANTIALLY IMPROVE OUR ABILITY TO MEASURE AMBIENT AIR TEMPERATURE AND, IN ADDITION, IT WOULD BE ACCURATE ENOUGH SO THAT IT COULD BECOME A STANDARD INSTRUMENT FOR THE CALIBRATION OF FIE ...

EXTENSIVE RESEARCH IS BEING CONDUCTED TO OPTIMIZE NITROGEN (N2) FIXATION RATE IN LEGUMINOUS CROPS, AND TO INTRODUCE N2-FIXING ABILITY INTO NONE-LEGUMINEOUS CROPS. THIS RESEARCH REQUIRES A METHOD TO CONDUCT CONTINUOUS, NININVASIVE MEASUREMENTS OF NITROGENASE ACTIVITY IN INTACT NODULATED ROOTS, PARTICULARLY IN FIELD STUDIES. CURRENTLY AVAILABLE METHODS ARE EITHER INHIBITORY OR ONLY PROVIDE MEASUREME ...

Until now gamma radiation detection has required large single crystals of sensitive materials that are difficult to produce consistently on an industrial scale. In collaboration with a research group at the University of Texas at Arlington, Agiltron proposes to develop a new class of nanocomposite scintillator materials. The radiation detection characteristics of the synthetic nanoparticles in the ...

"Situation or Problem" Immersion frying is a popular food preparation method. U.S. Consumers enjoy billions of pounds of low cost and taste appealing fried foods annually. Sensorial properties include golden color, crunchy crust, tender-moist core, and pleasing flavors. Unfortunately, immersion-fried foods have high caloric content due to their high oil content and are considered to have a negativ ...
