    Notes: Wheat starch was hydrolyzed using microwave energy. Starch suspensions (10%) acidified with hydrochloric acid to pH 1.85 were heated at 0.18 milliamperes microwave. energy in sealed glass tubes for various times. Liquefying and coloring were the most obvious visible changes during hydrolysis. With extended heating times, temperature, pressure, and total acidity increased causing darker hydrolyzates and charred residue formation. Paper chromatography showed sugars ranging from G1 to G5. Starch hydrolysates had total sugars, reducing sugars, and glucose as high as 94.81, 88.69, and 83.56%, respectively, based on original starch. Sugar syrups of high dextrose equivalent can be produced within a short time by using microwave energy.

    On the mortality ofTribolium castaneum adults treated sublethally as larvae with pirimiphos methyl,Nosema whitei and pirimiphos methyl—N. whitei doses (1988)

    Description / Table of Contents: Résumé Les larves nouvelles nées deTribolium castaneum ont été traitées avec 0,5 ppm de pirimiphosméthyl, 1,6×104 spores/g deNosema whitei seule et le mélange 0,5 ppm+1,6×104 spores/g et l'on a enregistré la mortalité des adultes en résultant. Tous les traitements augmentaient la mortalité des Coléoptères d'une manière significative (P〈0,01) quoique la dose combinée donnait une mortalité inférieure à celle obtenue par l'utilisation soit des micro-sporidies, soit de l'insecticide seul.
    Notes: Abstract NeonateTribolium castaneum larvae were treated with 0.5 ppm pirimiphos methyl, 1.6×104 spores/gNosema whitei alone and 0.5 ppm+1.6×104 spores/g combined and the resulting adult mortality recorded. All treatments increased the mortality of the beetles significantly (P〈0.01), though the combined dose gave a lower mortality than either the microsporidian or the insecticide alone.

    Charged charm production in proton-emulsion interactions at 400 GeV/c (1985)
    Springer
    The European physical journal 27 (1985), S. 325-328 
    Details
    ISSN: 1434-6052
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A study of charged charm production is made at 400 GeV incident energy of protons in nuclear emulsion. A total of 7005 primary stars have been scrutinized to look for charm particle decays in the forward cone within a decay distance of 100–1,000 μm (3,056 stars) and 100–2,000 μm (3,949 stars). In all 10 charm candidates decaying to 3 charged particles plus neutrals have been observed. Background due to secondary interactions for events of such topology is estimated to be ≈3. Background due to strange particle decays is estimated to be negligible. The rest of the events are attributed toΛ c + andD ± decays. This leads to a value of 91±35 μb/nucleon for the total charged charm production cross section. Using production cross section forD ± from other experiments we obtainΛ c + production cross section as 62±27 μb/nucleon. Two cases of pair production of charm have been seen.

    Details
    ISSN: 0271-2091
    Keywords: Finite element ; Interlayer slip ; Stress distribution ; Pressure drop ; Engineering ; Engineering General

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: The observed phenomenon of slip between the layers of a flowing slurry is modelled mathematically by a finite-element-based numerical technique. This technique enables us to quantify variables such as the slip velocity and shear stress distribution at the interlayer boundary and the pressure drop within the flow domain.

    Generalized diffuse interface model for determination of kinetic parameters in high-temperature internal corrosion reactions (gas/solid system) (1998)
    New York, NY : Wiley-Blackwell

    Notes: Diffuse Interface Model (DIM) is introduced to describe the mechanism of high-temperature corrosion/internal oxidation. The zone has dissolved oxygen and metal atoms diffuse and react resulting in the inward movement of zone. The high-temperature oxidation data for cobalt, iron, and nickel, which are for metal deficit (p-type), have been analyzed using a nonlinear optimization method to obtain the optimal values for different parameters, diffusivity of metal atoms in metal oxide, diffiusivity of gaseous species in the corrosion product, diffusivity of oxidant in the unreacted solid (metal or alloy), the rate constant for the reaction and the fraction of the zone reacted. The expression for diffusivity in the reaction zone has been modified by relating diffusivities of the product layer and the core as function of fraction of zone reacted. The model was applied to the experimental data for the high-temperature oxidation of cobalt, iron, and nickel by pure oxygen at an atmospheric pressure. The model predicts the values of diffusion coefficients, preexponential factors, and activation energies for diffusion process, which are generally compared favorably with those reported in the literature. Linear relationship are derived relating the diffusion coefficient in the core and product layer to the parabolic rate constant which is valid for iron, cobalt, and nickel for high-temperature oxidation (900-1350°C) by oxygen at an atmospheric pressure according to the following equations:\scriptfont4=\seveni \scriptscriptfont4=\fivei $$D_{\rm P}=1.4\times 10^{-8}\ \it k_{g}$$ $$D_{\rm C}=6.9\times 10^{-9}\ \it k_{g}$$The results of the model have been successfully used to predict the experimentally determined parabolic rate constants for the oxidation of cobalt at high temperatures for two different investigators [6,7] under similar conditions. © 1998 John Wiley & Sons, Inc.
