The purpose of this project is to develop new language training methods that help guard against language skill decay, and help recover from skill decay when it has occurred. It leverages previous DoD and ONR investments in language learning technology, but it focuses squarely on the language attrition problem. In addition to providing language training that is resistant to decay, it pays particula ...

Well over 50 % of US land area constitutes low wind-speed sites, yet wind turbines are either not effective or only marginally effective in such low winds. To extract significantly more energy from such DOE Class 1 or Class 2 winds requires substantially increasing turbine blade rotor diameter (wind power is proportional to the square of the blade diameter). However, due to limitations on turbine ...

The problem: Nutrient concentration has a direct effect on the yield and quality of plants. However, despite their importance, they are frequently over applied and, if their concentration is thought to be incorrect, they are discarded into the environment and replaced with a new solution. This leads to nutrient waste and widespread environmental contamination of aquatic, ground and drinking water ...

Typical agrochemical sprayers use nozzles to atomize a liquid stream into droplets; these droplets then travel to the target. Nozzles may be selected to provide a range of droplet sizes, spray distribution patterns, and flow rates for a desired liquid material application. Spray distribution, droplet size, and flow rate are important considerations in achieving a high quality agrochemical applicat ...

Citrus canker, caused by Xanthomonas axonopodis pv. citri, a bacteria associated with citrus leafminer (CLM), Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) damage, and Huanglongbing (HLB) . Successful completion of this project will provide citrus growers with a valuable tool for managing these two terrifying diseases, and enhance the diagnosis of diseased trees, even in the beginn ...

Our Phase I research and development in laboratory bioassays, wind tunnel, caged trees, and small field trials, indicates that different approaches are needed to maximize contact of the moth with the source containing the insecticide. We found that optimizing an attract and kill formulation that actually attracts and kills the males, instead of disrupting their orientation, is a fine balancing act ...

$14.8 billion of foodservice disposables and packaging (plates, utensils, take out containers, meat trays, bowls etc.) are purchased each year in USA (Freedonia 2009). They are mostly made from Styrofoam/plastics and cause pollution and toxicity in production, usage and disposal. Cities and consumers are looking to increase landfill diversion rates and reduce pollution. Compostable products are st ...

Vapors produced during the process of refueling cars are a significant source of Volatile Organic Compounds (VOCs) emissions. Uncontrolled emissions cause economic losses and pollute the environment. This problem is exacerbated when the gasoline contains bioethanol because its presence increases the vapor pressure and volatility of the fuel. These increased fuel emissions from ethanol-gasoline ble ...

Biogas & Electric LLC proposes a novel low cost approach to NOx and SO2 removal through a combination of extended absorption and selective non-catalytic reduction. If efficacy in the proposed NOx removal process can be shown, the new method will be adopted by all proposed manure based anaerobic digestion projects in California, and shortly thereafter adopted by many other manure based anaerobic di ...

Soybean is the major source for production of edible oils worldwide and in United States. Pressing of the soybean into flakes followed by the solvent extraction with hexane (solvent) is most widely practiced for extraction of oil. Separation of solvent from oil-solvent mixture for solvent recovery and reuse is usually carried out by solvent evaporation. Evaporation (or distillation) demands consid ...
