    Notes: [Auszug] As a test of this hypothesis, Hendler and Green-berg5 have recently studied the metabolism of labelled y-glutamyl-glycine; but they found that this particular compound is not significantly involved in any of several living systems that incorporate amino-acids into proteins. The evidence presented ...

    Notes: [Auszug] Sickle-fibres constitute the most easily perceived evidence of the pre-natal check3-5. Of ten N/ + Aggrade lambs studied in a number of body regions, all had sickle-fibres on the shoulder patch and shoulder, and they were present on several necks, withers, sides and o backs, but not on any ...

    Notes: [Auszug] On one occasion when I was slowly condensing propane in a flask chilled with liquid nitrogen, I obtained what appeared to be such a mixture : that is, I obtained two distinct layers of liquid in the flask, one of which had the characteristic appearance of liquid oxygen. This experience suggested ...

    Notes: [Auszug] Substituting for M% the present value 1837 '56 m for the mass of the neutral hydrogen atom, it is found that MX is 1839-08 m, in excellent agreement with the experimental neutron mass 1839-05 m. This simple relation between the neutron and hydrogen atom is consistent with Eddington's1 concept of ...

    UV spectroscopy of metal volatilization during thermal plasma processing of waste glass melts (1996)
    Springer
    Plasma chemistry and plasma processing 16 (1996), S. 449-460 
    Details
    ISSN: 1572-8986
    Keywords: Spectroscopy ; volatilization ; iron ; nickel ; chromium ; waste vitrification
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Technology
    Notes: Abstract Atomic emission spectroscopy (AES) is used to monitor volatilization during waste vitrification with thermal plasmas. Model baste specimens consist of am alumino-silicate clay spiked with 10 wt. % Fe, Ni, or Cr. Specimens are vitrified in processing atmospheres with 0, 8.5, and 17 vol. % oxygen/argon concentrations. Particulate generated from condensation of the volatilized materials is collected following each specimen run and analyzed by energy dispersive X-ray analysis to determine composition. Spectra are collected from the ultraviolet range 240–380 nm in where the presence of metal vapor is readily detected. Correlation between line emission intensities and volatilization rates allows the establishment of provisional detection limits for the volatilization of Ni, Cr, Si, and Fe, of 1 × 103 g/s, 4 × 104 g/s, 2 × 104 g/s, and 5 × 105 g/s, respectively. The results of this investigation support the concept of using AES as an in-situ process monitor for feedback to optimize plasma processing of hazardous metal-containing waste.
