Abstract: Disclosed is the invention to conduct immuno-adsorption of free 25(OH) vitamin D from blood or blood components, notably serum or plasma, after which the absorbed material is measured. A fluoro-alkyl surfactant is used to enhance the solubility of Vitamin D and allow the measurement of free Vitamin D2. The invention thus employs a binding protein to absorb the free 25(OH) vitamin D. Thereafter the binding protein comprising the 25-OH vitamin D is subjected to a competitive binding assay with a labeled vitamin D compound, preferably radiolabeled, fluorescent labeled, luminescent labeled, biotin labeled, gold labeled or enzyme labeled. Alternatively the immunocaptured 25-OH vitamin D can be quantitated by mass spectrometry.

Abstract: A method is provided to reduce the surface temperature at high latitudes beneath mixed-phase low-level clouds. The clouds are seeded by ice crystals from dry ice pellets or from water droplets sprayed by effervescent nozzles or by injection of silver iodide. The ice crystals convert supercooled liquid water in the clouds into ice crystals by the Wegener-Bergeron-Findeisen process. Ice-only clouds are more transmissive to long wavelength radiation than mixed-phase clouds, thereby allowing more surface long wavelength radiation to escape into space or into higher, colder regions of the atmosphere.

Abstract: An irrigation system having a pipeline supported by one or more towers includes an improved truss connection system having a means for readily adjusting a crown height of the pipeline. A pair of cooperating members define a joint which selectively couples headed ends of adjacent truss rods together to form a truss rail of a truss system that supports the pipeline. A single fastener may fasten the cooperating members, a strut, and a cross-member together at the joint. A length of the truss rail may be decreased by holding the truss rods closer together. In an aspect, the headed ends of the adjacent truss rods are held closer together by inserting a shim in one of the joints. Decreasing the length of the truss rail increases the deflection of the pipeline and raises the crown height.

The geofence may be modified to a second size or a different shape based on the historical scans of the GPS data.
