The use of sub-therapeutic concentrations of anti-microbial agents in animal feed has contributed to theproductivity of the U.S. meat and dairy industries by preventing infectious diseases, by decreasing theamount of feed required and by increasing the rate of animal weight gain. However, failure to observerecommended practices of drug withdrawal can result in concentrations of antibiotic residue ...

The proposed program will isolate bacteriophage that demonstrate sensitivity and specificity for rapid detection of specific pathogens in foods. Current food pathogen test kits for E. coli and Salmonella that are antibody based require 18-24 hours to complete. Food processors need rapid test kits to optimize inventory management, reduce recalls and keep pace with government regulations. A preli ...

THE UNCERTAINTY IN MEASURING NEUTRON DOSE EQUIVALENT RATES RESULTS IN UNCERTAINTY IN ASSIGNMENT OF THE PROPER DOSE TO OCCUPATIONAL RECORDS AND CAN RESULT IN IMPROPER IMPLEMENTATION OF CONTROLS TO LIMIT THE EXPOSURE. A NOVEL PORTABLE NEUTRON SPECTROMETER IS PROPOSED WHICH WILL REDUCE THE UNCERTAINTY OF SUCH MEASUREMENTS TO LESS THAN 20%. MANYCOMPONENTS OF THIS DEVICE ARE COMMERCIALLY AVAILABLE. SYS ...

WE PROPOSE TO DEVELOP A SIMPLE TO USE, QUANTITATIVE DEVICE TO ACCURATELY MEASURE SOIL WATER CONTENT WITH SUFFICIENT RESOLUTION TO DEFINE WETTING FRONTS DUE TO RAIN EVENTS IN DEPTH PROFILES. THIS GEOPHYSICAL TOOL SENSES CHANGE IN THE ELECTROMAGNETIC ENVIRONMENT, SPECIFICALLY THE DIELECTRIC CONSTANT OF THE SOIL, WHICH IS DIRECTLY RELATED TO SOIL WATER CONTENT. THE SOIL WATER CONTENT PROFILING DEVICE ...

Water quality and soil erosion are high priority issues for U.S. agriculture. In more humid areas of theU.S., vegetation filter strips have proven to be an effective method of reducing erosion and improvingwater quality. Filter strips are less effective in the West due to sparser vegetation and more variablerainfall. In addition, establishment of vegetation is more difficult in many western wat ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...

TWO APPROACHES WILL BE EXAMINED TO SIGNIFICANTLY IMPROVE THESENSITIVITY OF LAUNDRY MONITORS TO DETECT AND SPECIFY LOCATION OF HOT PARTICLES ON LAUNDERED GARMENTS. THESE PROPOSED TECNIQUES HAVE HIGH POTENTIAL FOR DETECTING BOTH LOW ENERGY BETA AND ALPHA PARTICLE RADIATION AS WELL AS IMPROVING SENSITIVITY BY REDUCING BACKGROUND COUNT RATE.

The ready-to-assemble (RTA) construction system is a new method for assembling wood structuresbuilt from the following engineered wood products: parallel strand lumber (PSL), laminated strandlumber (LSL), and laminated veneer lumber (LVL). The RTA system is designed for rapid assemblyby small crews of unskilled labor using common hand tools. The design of the RTA systemincorporates engineered w ...

PREDICTING THE RATE OF SOIL WATER MOVEMENT AND THE IMPACT OFAGRI-CHEMICALS ON WATER RESOURCES IS VITALLY IMPORTANT TO MANAGING AGRICULTURE, FOR OPTIMIZING PRODUCTIVITY AND MINIMIZING ENVIRONMENTAL IMPACT. SOPHISTICATED MODELS FOR MAKING SUCH PREDICTIONS ARE AVAILABLE, BUT DATA ON SOIL HYDRAULIC PROPERTIES ARE DIFFICULT AND OFTEN EXPENSIVE TO OBTAIN. IN FACT, AT DEPTHS BELOW THE ROOT ZONE THERE IS ...
