    Aerobic Microflora of Commercially Harvested, Transported and Cryogenically Processed Col lards (Brassica oleracea) (1987)

    Notes: Samples of spring and fall harvested collards were obtained at critical stages in a normal harvesting, transportation and cryogenic processing operation and microbiologically analyzed for total plate counts, En-terobacreriaceae counts, and yeasts and molds. Operations that involved extended holding times and mechanical handling tended to increase all counts significantly while blanching and blast freezing with liquid N2 reduced counts to acceptable levels. Differences were significant in all counts by sampling points and dates. Prominant genera of Enterobacteriaceae isolated from the frozen product were those normally associated with soil contamination and not normally considered pathogenic to humans.

    The May 1985 superoutburst of OY Carinae: I. Structure of the outer disk from optical and IR observations (1987)

    Notes: Abstract We present optical and IR observations of the dwarf nova OY Car during the May 1985 superoutburst. From them we find that the superhump has a temperature of ∼8000K and an area of order half the size of the red dwarf or accretion disk. We also compare the behaviour during two simultaneous optical/IR observations. Whilst the light curves in the two pass bands are similar during one observation, in the other observation they show marked differences that may be due to a cool region in the outer disk.

    Strontium isotope variations in lower tertiary-quaternary volcanic rocks from the Kurile island arc (1987)
    Springer

    Notes: Abstract Average 87Sr/86Sr ratios for lavas from Quaternary and Pleistocene volcanoes of the Kurile island arc, NW Pacific, decrease from 0.7035 in the south to 0.7032 in the north. The northern Kuriles are characterised by K2Oricher volcanics and by an older crust. Varying ratios show no simple relation to crustal thickness or geochemical indicators of crustal contamination. This is thought to reflect the immature character of the crust — its simatic composition, low Rb/Sr ratios and youthfulness. Older lavas from the Kuriles (Lower Tertiary, Miocene) have similar or slightly higher 87Sr/86Sr ratios; some have suffered slight alteration and possibly crustal contamination. Quaternary volcanics from the Kurile and Aleutian arcs have the lowest 87Sr/86Sr ratios of all circum-Pacific arcs and this may be ascribed to (a) the isotopic individuality of the landward North American plate and/or (b) the high degree of mechanical coupling between the Pacific and North American plates reducing the amount of subducted 87Sr-rich sediments and seawater. An isotopic boundary between island arcs is located in central Hokkaido. The primary basaltic magmas of the Kuriles were derived from mantle recently contaminated by radiogenic Sr. Subsequent fractionation to andesites and dacites occurred by closed-system fractional crystallization.

    Estimating true scores in kinship data (1987)
    Springer
    Behavior genetics 17 (1987), S. 487-491

    Notes: Abstract Estimated true scores are occasionally used to provide an estimate of scores which would be obtained if measurement error could be removed from fallible measures. When one knows only a test's relibility and an observed score for each subject, true scores are estimated by regressing observed scores toward the group mean. When relatives' observed scores are also available, estimates of true scores can be improved by using the additional information. Observed scores of subjects and relatives can be used as predictors of subjects' true scores in a multiple regression. The resulting formula is presented for the case in which only one relative's score per subject is known. Estimation of true scores for the general case ofN relatives per subject is also discussed.

    Modeling of slow dynamics in the oxidation of CO over supported silver (1987)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 33 (1987), S. 1971-1976

    Notes: The oxidation of CO over aluminum-supported Ag was studied at 147°C using transient experiments. Long-time-scale dynamics were observed that could not be explained by previously postulated kinetic mechanisms for this reaction system. A model is presented with kinetic parameters estimated from steady state and transient data that is able to reproduce a variety of cycled feed stream experiments. The model incorporates a slow reversible step which forms an adsorbed oxygen species that blocks reaction sites.

    Residual stresses in turned AISI 4340 steel (1987)
    Springer
    Experimental mechanics 27 (1987), S. 80-85

    Notes: Abstract The residual-stress distribution in the surface region of workpieces of annealed AISI 4340 steel that is turned under unlubricated conditions is determined using a deflection etching technique. The absolute value of the residual stresses at the machined surface are low and increase with an increase in depth beneath the machined surface to a maximum. They then decrease with a further increase in depth eventually becoming vanishingly small. Peak residual stresses are tensile at cutting speeds of 0.5 and 1.0 ms−1 and are compressive at a cutting speed of 1.5 ms−1 for all feed rates and depths of cut. Peak residual stresses and depth of the stressed region increase with an increase in feed rate and depth of cut, but decrease with an increase in cutting speed. The results of this investigation can be interpreted in terms of the variation of tool forces with cutting conditions.
