Scientists with the Agricultural Research Service (ARS) and various government agencies and private institutions have provided a great deal of fundamental information relating spectral reflectance and thermal emittance properties of soils and crops to their agronomic and biophysical characteristics. This knowledge has facilitated the development and use of(More)
Membrane vesicles isolated from Azotobacter vinelandii strain O by lysis of spheroplasts in potassium of sodium phosphate buffer develop a transmembrane electric potential during respiration. The magnitude of this potential was determined by three independent methods: (i) fluorescence of 3,3'-dipropylthiodicarbocyanine and 3,3'-dihexyloxacarbocyanine; (ii)(More)
