  • The nature and properties of amorphous colloids formed from Mazama tephra

    Creator:
    Dingus, Delmar DeLee
    Abstract:
    Soil samples from the Mazama tephra deposit were collected from the AC and C2 horizons at five different locations along the axis of the main depositional lobe. The clay fraction from the samples was recovered and studied by means of chemical, x-ray, DTA and electron microscopy methods in order to...

  • Diffusion and surface reaction processes of absorption on surfaces of soil particles in unsaturated soils

    Creator:
    Yingjajaval, Suntaree
    Abstract:
    At present the adsorption kinetic of ions by soil particles is considered to be a surface reaction. When the transport of solutes in soils is described using the one-dimensional flow equation, it becomes a serious problem that lateral diffusion of ions from the bulk solution towards the soil surfaces is...

  • Long term temporal perspectives for the demersal fish assemblages of Georges Bank with implications for management and modeling

    Creator:
    Overholtz, William Joseph
    Abstract:
    Questions of assemblage persistence, resiliency arid continuity in time were investigated with data from seasonal bottom trawl surveys conducted by the Northeast Fisheries Center, Woods Hole, Massachusetts, from 1963-1978. Cluster analysis proved to be a useful statistical method for delineating assemblage boundries and corresponding resident demersal fish components from Georges...

  • Wind turbulence input model for horizontal axis wind turbines

    Creator:
    Lin, Shuh-ren
    Abstract:
    In order to estimate wind turbine residL2;characteristics in the presence of atmospheric turbulence, the important atmospheric sources for the force excitations felt by the wind turbine system must be identified and characterized. The goal of this research is to develop the wind turbulence input model for horizontal axis wind turbines....

  • Local scour at isolated obstacles on river beds

    Creator:
    Huang, Cheng-Chang
    Abstract:
    Maximum equilibrium scour depths, equilibrium scour volumes, and induced equilibrium movements at isolated obstacles on river beds were investigated in clear-water scour. The research was achieved by a systematic flume study based on the results of dimensional analysis of local scour. The main tested obstacles for local scour were cubes....

  • Ternary arithmetic in direct digital control systems

    Creator:
    Seamans, David Alvin
    Abstract:
    The development of new electronic devices and design procedures applicable to ternary switching circuits suggests that it might be desirable to use ternary arithmetic in direct digital control systems. The advantages of decimal, binary, and ternary arithmetic in digital computers are discussed and a set of rules for signed -digit...

  • The effect of selected potassium salts on the availability of soil manganese

    Creator:
    Westermann, D. T. (Dale Thomas), 1941-
    Abstract:
    Incubation experiments with an acid poorly drained soil have shown that the application of neutral soluble salts influenced the level of extractable Mn. The application of a salt which lowered the soil pH either increased the extractable Mn or retarded the oxidation and/or fixation of extractable Mn. This effect was...

  • Effect of a direct-fed microbial on performance of single comb white leghorn chickens

    Creator:
    Nahashon, Samuel N.
    Abstract:
    Six experiments were carried out with Single Comb White Leghorn laying chickens to assess the effect of feeding a source of direct-fed microbials (Lactobacillus; Lacto) and its carrier [condensed cane molasses solubles (CCMS)] on the retentions of fat, nitrogen and several minerals; on the status of the pH of the...

  • Heat induced compounds in milk

    Creator:
    Scanlan, Richard A.
    Abstract:
    Milk, preheated at 82°C for 30 minutes, was heated to 146°C for four seconds (UHT-treated) and cooled to 5°C in a tubular heat exchanger. Immediately after heat treatment, 20 gallons of heated milk were vacuum distilled at 30°C in a semi-continuous, reduced pressure glass apparatus. Twenty gallons of non-heated milk...

    Creator:
    Blanks, George Anthony
    Abstract:
    Six groups of goats were used in the study. These were the normal group (Saanen, French Alpine, and Nubian breeds), 1/4 pygmy group (first backcross to normal), 1/2 pygmy group (F1) 3/4 pygmy group (first backcross to pygmy), 7/8 pygmy group (second backcross to pygmy), and pygmy group0 The mean...
