    Feedlot manure top dressing for irrigated pasture: Good agricultural practice or a health hazard? (1976)
    Springer
    Bulletin of environmental contamination and toxicology 16 (1976), S. 536-540

    Notes: Summary Top dressing a spray-irrigated pasture of orchardgrass with 125 t/ha of overwintered beef feedlot manure almost doubled the yield of dry forage: 6 353 kg/ha vs. 3578 kg/ha for the plots receiving no manure. Even at this rate of application, the manure did not contaminate the irrigated grass with enteropathogenic bacteria after irrigation. When the grass became contaminated through the use of fecally polluted irrigation water, the fecal coliforms, indicator organisms with survival characteristics similar to the salmonellae, were effectively eliminated from the grass after exposure to 65 hr of bright sunlight.

    Calculated temperature distribution during laser annealing in silicon and cadmium telluride (1979)
    Springer
    Applied physics 19 (1979), S. 313-319

    Notes: Abstract By solving the time-dependent heat flow equation, the temperature reached by silicon and cadmium telluride surface layers under high power density ruby laser pulsed illumination, is calculated. The results are presented in directly useful figures allowing the determination of the surface temperature, its evolution towards the bulk as a function of time... In particular, it should be noticed that for a 25 ns half-power width, pulses of 0.8J/cm2 are sufficient to melt the top of an amorphous silicon layer, this value becomes noticeably lower for cadmium telluride.

    The measurement and significance of energy in acoustic-emission testing (1977)
    Springer
    Experimental mechanics 17 (1977), S. 347-353 
    Details
    ISSN: 1741-2765
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract A technique for measuring the energy sensed at an acoustic-emission transducer is presented that utilizes a squaring circuit and digital integrator. Theoretical relationships between energy and other more conventional acoustic-emission parameters, such as counts and RMS voltage, are derived for certain idealized cases. Experimental results from the following types of tests are presented: (1) unflawed tensile (‘continuous’ emission); (2) precracked stress-corrosion cracking; (3) precracked fracture toughness; and (4) fatigue-crack growth. Energy, counts, RMS-voltage, energy/event and counts/event measurements are included. In the case of unflawed tensile specimens, energy techniques appeared somewhat superior to counts. In all other cases, a direct relationship between counts and energy was obtained. Energy measurements tended to give a larger weight to higher amplitude events. Other than this, energy measurements appeared to have no advantage over counts. The theoretical relationship predicted between energy/event and count/event agreed quite well with experimental observations. Overall, the test results presented indicate that energy techniques provide no significant advantage over counting threshold crossings in cases in which crack extension in metals is the primary source of acoustic emission.

    Identification of 4,6-O-(1-carboxyethylidene)-D-galactose by combined gas chromatogrphy mass spectrometry (1978)

    Notes: Combined gas chromatography mass spectrometry was used to separate and identify a carrageenan component suspected of being the acid ketal 4,6-O-(1-carboxyethylidene)-D-galactose. The mass spectral fragmentation pattern is presented as evidence for the presence of this component in the carrageenan from Petrocelis middendorfii (P. francisana).
