Mycotoxins are compounds produced by certain species of fungi which infect grains such as corn and peanuts. Among the most common and most toxic of these are the aflatoxins (AF), with AFB1 and AFG1 recognized as potent carcinogens in addition to their other negative effects. Contamination results in large economic losses at all levels of food production. Few effective means of treating contamin ...

There is a continuing need for reliable cloud observations to drive climatic UV-B prediction models. Traditionally, observations such as cloud cover are made by human observers, and thus often suffer from uncertainties due to the subjectivity of the observer. Cloud cover data is especially important in UV-B hazard prediction, as well as storm prediction. It is generally accepted that UV-B doses ...

The energy from the sun is the overall engine that drives our climate. Widespread concern over thedepletion of the stratospheric ozone layer, and the effect that this may have on UV-B irradiance levelsat the surface of the Earth, has highlighted the need for improved technology for precisely measuringsolar ultraviolet radiation. Instruments deployed in the field require frequent calibration to e ...

THIS RESEARCH PROPOSAL DEALS WITH THE DEVELOPMENT OF A GAMMARAY DOSIMETER THAT IS BASED ON A SOLID STATE DETECTOR AND A MICROPROCERSSOR AND WILL DISPLAY THE DOSE AND DOSE RATE OF THE SKIN, AT A GIVEN DEPTH OF THE BODY OR THE BODY-AVERAGED DOSE, BY MEASURING THE SPECTRUM OF A RADIATION FIELD AND CALCULATING THE TISSUE EQAUIVALENT DOSE OF INTEREST. THE DETECTOR IS A PROPRIETARY DESIGN FEATURES OF TH ...

AS THE AQUACULTURE INDUSTRY HAS GROWN, LITTLE ATTENTION HAS BEEN GIVEN TO THE ENVIRONMENTAL IMPACTS OF AQUACULTURE, UNTIL RECENTLY. BETTER COLLECTION TECHNIQUES FOR FISH WASTEMATERIAL, WHICH IS IN THE FORM OF A SLURRY AND IS APPROXIMATELY 95% WATER, HAVE INCREASED OPERATING COSTS FOR THE AQUACULTURE INDUSTRY TO TREAT EFFLUENTS AND DISPOSE OF SOLIDS GENERATED. FUTURE REGULATIONS MAY LIMIT CURRENT D ...

CURRENTLY, POULTRY PRODUCTS WHICH ARE PROCESSED AND DISTRIBUTED IN A NON-COOKED FORM, MAY CONTAIN SIGNIFICANT NUMBERS OF PATHOGENIC BACTERIA SUCH AS SALMONELLA, LISTERIA AND CAMPYLOBACTER. POULTRY PROCESSING TECHNOLOGY HAS NOT AT THIS TIME DEVELOPED A SYSTEM OF EVISCERATION THAT DOES NOT CONTAMINATE THE CARCASS TO SOME EXTENT. TECHNOLOGY TO ELIMINATE THESE CONTAMINATING PATHOGENS FROM THE CARCASS ...

THE LIGASE CHAIN REACTION (LCR) ENABLES AS FEW AS 10 DNA TARGETS TO BE AMPLIFIED TO LEVELS DETECTABLE USING MANY CONVENTIONAL DETECTION METHODS. THE AMPLIFICATION TECHNOLOGY CAN BE APPLIED TO THE DETECTION OF SALMONELLA IN FOOD SAMPLES WITH BENEFITS REALIZED IN THE REDUCTION OF PRE-ENRICHMENT AND SELECTIVE ENRICHMENT GROWTH TIMES AND IMPROVEMENT IN ASSAY SENSITIVITY, SURPASSING ALL CURRENT DETECTI ...
