    Distribution and Probable Source of Nitrate in Ground Water of Paradise Valley, Arizona (1980)
    Oxford, UK : Blackwell Publishing Ltd
    Ground water 18 (1980), S. 0 
    Details
    ISSN: 1745-6584

    Topics: Energy, Environment Protection, Nuclear Power Engineering , Geosciences
    Notes: Field investigations in Paradise Valley, Arizona, conducted during 1974 and 1977, delineated areas of ground water with up to 132 mg/1 nitrate. Two alternative interpretations are developed as to possible sources of the excess nitrate. The first is a conventional interpretation identifying the use of nitrogenous fertilizers as the primary source and disposal of treated waste-water effluent as a secondary source. An alternative interpretation identifies the source as a sand and gravel unit that is interpreted as a braided-stream deposit, located about 152 m (500 ft) below the land surface. The source of the nitrate may have been NH4Cl leached from tuffs in the adjacent Superstition Mountains, subsequently oxidized to nitrate and deposited in abandoned channels of the braided-stream complex. At present, it is not possible to make a definitive choice among the possible nitrate sources.

    Notes: [Auszug] MORRONE ET AL. REPLY-For us the most intriguing aspect of Harmon and Julesz's1 ingenious demonstration is that blocking does not merely degrade the image, but renders recognition impossible. Normal masking (such as their Fig. 3a1 or indeed our Fig. 1d2) degrades the image but leaves it still ...

    Notes: [Auszug] In addition to the threshold measurements of temporal summation it is also well established that super-threshold stimulation leads to a sensation which persists in vision for some time after the termination of the stimulus4, again, for about 120 ms in daylight5,6. Perhaps the most direct ...

    Notes: [Auszug] To detect which proteins were actually produced by the worms, S. mansoni of the NIH strain were perfused from C57BL/6B mice at 70 days post-infection, mechanically separated according to sex, and incubated for 24 h in medium HB597 (Connaught) with 10% fetal calf serum and 8 µCi ml-1 ...

    Notes: [Auszug] A detail of Leonardo's 'Mona Lisa' was digitized into 256 x 256 pixels, using a flying spot scanning system made up of a Cromemco microcomputer, an oscilloscope (Hewlett Packard 1335A), a lens and a photometer (Spectra Pritchard 1980A). The digitized file was transferred to a larger computer ...

    Notes: [Auszug] The absorption of a photon by light-adapted bacteriorhodopsin (bRLA), the purple membrane protein of the Halo-bacterium halobium, initiates a series of transformations13, reminiscent of the bleaching sequence of rhodopsin. The primary photochemical product, K, is a bathochromically shifted species; ...
