A comparison of the soil moisture response of three 1–4 GHz radiometers from truck and aircraft platforms at a variety of lest sites indicates that microwave remote sensing of bare soil produces repeatable and quantifiable results regardless of geographic location and sensor system used. The combined microwave sensitivity of these data sets appears to be of the order of ? 3–4deg?K per 1 per cent change in volumetric soil moisture for L-band wavelengths ( ? 2–7 deg K per 1 per cent soil moisture if watersheds characterized by vegetation and surface roughness are included). With the addition of appropriate algorithms to handle the effect of roughness and vegetation, these results demonstrate the potential of microwave remote sensing for estimating soil moisture over large areas. 相似文献

Monoclonal Antibodies to Porcine Thermal-Stable Muscle Protein for Detection of Pork in Raw and Cooked Meats 总被引:3,自引:0,他引:3
Four hybridoma cell lines secreting monoclonal antibodies (MAbs) specific to porcine thermal-stable muscle proteins (TSMPs) were developed. The MAbs reacted with three protein bands (20.5, 22 and 24 kD) from raw pork extract; the protein band (24 kD) which was also present in cooked pork was identified as porcine-specific TSMP. Epitope analysis indicated four MAbs recognized same or closely located antigenic sites on the pork TSMP. The developed MAb-based indirect enzyme-linked immunosorbent assay (ELISA) enabled the detection of pork in raw and cooked heterogeneous meat mixtures as low as 10 g/kg. The curvilinear relations of second-degree polynomial (r2 > 0.995) between pork concentrations and ELISA responses enabled quantifying degree of adulteration of pork in meat products. 相似文献
