  • Periodate oxidation of cellulose - a complete kinetic study

    Creator:
    Chandan, Bhaskar Arjundev
    Abstract:
    The effect of over-oxidation on periodate oxidation of cellulose was studied. It was found that the over-oxidation process has a significant effect on the overall reaction. An integrated rate equation was formulated. The oxidation of internal glucose units is second-order overall, first order with respect to both periodate and cellulose;...

    Schuttler, Patti L.
    Abstract:
    Soybeans were grown in hydroponic solutions and in perlite to devise procedures to measure plant mineral accumulation and solution depletion over time. Electron emission spectrometry and micro-Kjeldahl-autoanalyzer analytic techniques were used to monitor mineral content of individual plants and their corresponding solutions. An automated computer assisted system of converting raw...

  • Tracheal mite parasitism of honey bees

    Creator:
    Royce, Lynn A.
    Abstract:
    The tracheal mite, Acarapis woodi (Rennie), parasitizes the honey bee, Apis mellifera L., an insect used extensively by humans for pollination of domestic crops and for bee products, primarily honey. This parasite was first discovered in 1921 on the Isle of Wight, a small island situated in the English Channel...

  • Winter supplementation and delayed weaning of an autumn calving beef herd under western Oregon conditions

    Creator:
    Buehner, Heidi Renata
    Abstract:
    Two management systems were evaluated in terms of the effects on cow condition score and body weight changes and calf growth rates. The management systems evaluated were winter supplementation of energy, winter creep feeding and delayed weaning. The calves used in this study were born in September and October of...
