    Sensory Evaluation of Regina Freestone Peaches Treated with Low Doses of Gamma Radiation (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 50 (1985), S. 0 
    Details
    ISSN: 1750-3841

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: regina freestone peaches from california were given low postharvest doses of gamma radiation (65-75 krads) and were compared with non-irradiated controls approximately one month after harvest. Practiced judges were used, with a technique of minimal cross-sensory interference, as an analytical tool to guide subsequent instrumental analysis. Strong differences were found in odor and components of taste not associated with sweetness. Lesser trends were noted for firmness and appearance. Untrained subjects also detected gross sensory differences.

    Initial Sensory Evaluation of Bing Cherries Treated with Low Doses of Gamma-Radiation (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 50 (1985), S. 0 
    Details
    ISSN: 1750-3841

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Bing cherries from California were given low postharvest doses of gamma radiation (60-80 Krads) and were compared with nonirradiated controls during a period 3-11 days after harvest. Irradiated cherries showed a greater degree of shrivelling, a trend to be softer on chewing and also exhibited flavor differences. Trends for consistent differences in firmness tested manually, darkness of skin color and degree of brown blemishing were not noted.

    Sensory Evaluation of Navel Oranges Treated with Low Doses of Gamma-Radiation (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 50 (1985), S. 0 
    Details
    ISSN: 1750-3841
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Navel oranges from two locations in California were given low postharvest doses of gamma radiation (60 - 80 Krads) and compared with nonirradiated controls for taste, flavor, odor, firmness, degree of orange color, degree of brown blemishing, ease of peeling and intactness of the membranes on sectioning. Practiced judges were used as an analytical screening tool using minimal cross-sensory interference, while untrained subjects were used to determine whether changes might be distinguished by‘nonexperts’. Greatest differences were found for degree of blemishing, lesser differences for flavor by mouth and odor and some trends for taste, color, texture and ease of peeling.

    Numerical simulation of unsteady fluid flow and propagation of a circular hydraulic fracture (1985)
    New York, NY [u.a.] : Wiley-Blackwell
    International Journal for Numerical and Analytical Methods in Geomechanics 9 (1985), S. 1-14 
    Details
    ISSN: 0363-9061
    Keywords: Engineering ; Engineering General

    Topics: Architecture, Civil Engineering, Surveying , Geosciences
    Notes: A computational procedure is developed for solving the problem of a circular hydraulic fracture propagating under the action of frac-0fluid being pumped in at a central wellbore. The crack is modelled as continuous distributions of ring dislocations and the resulting elasticity singular integral equation is solved numerically. The fluid flow equations are approximated by local and global interpolation finite difference schemes. The coupling between elasticity and fluid flow is handled numerically, by, two different algorithms: one iterates on crack tip velocity whereas the other varies the time step size until it agrees with the chosen increment in crack length. Sample results are given; it is found that the velocity algorithm is computationally more, efficient and more stable. The model allows detailed tracing of pressure distribution and fluid flow in the fracture, even under complex conditions of cyclic injection and fluid rheology. It may serve as a stand-alone model of (horizontal) hydrafracs-especially at shallow depths-or it may be used as a reference frame to test the various numerical formulation/algorithms required for the ongoing development of a fully 3-D hydrafrac simulator.
