Theoretical and experimental evaluation of transfer of 2, 4-dichlorophenoxyacetic acid in porous media

Creator:: Saxena, Subodh Kumar, 1942-
Abstract:: Experiments were conducted to study the effect of pore size distribution on the diffusion of 2, 4-Dichlorophenoxyacetic acid (carbon- 14) through water saturated porous media. Eight size fractions of glass beads were used representing the porous media. It was found that as the average particle radius, and hence pore radius,...

An evaluation of soil warming for increased crop production

Creator:: Rykbost, K. A.
Abstract:: In regions where soil temperatures limit plant growth, artificial soil warming may be an economically feasible practice. This hypothesis was evaluated in a soil warming experiment near Corvallis, Oregon. This experiment was prompted by the observation that multiple use of waste heat discharged in the condenser cooling water of thermal...

Mechanisms of lactose utilization by lactic acid bacteria : enzymic and genetic studies

Creator:: McKay, Larry L.
Abstract:: To learn more about the role β-galactosidase plays in rate of acid production in milk by lactic acid bacteria, several lactobacilli were examined for this enzyme. Cells from different species were grown in lactose broth to induce β-galactosidase activity. The specific activities of whole, solvent treated cells, and of cell-free...

Pore size distributions as measured by the mercury intrusion method and their use in predicting permeability

Creator:: Klock, Glen O.
Abstract:: A number of investigators have proposed equations to predict the permeability of porous media. Most of their equations are based on the distributions of the sizes of the various contributing pores in the medium. Presently the pore size distributions of agricultural soils are most commonly obtained from soil water release...

Circular dichroism spectroscopy and the conformational analysis of globular proteins in the native and denatured state

Creator:: Compton, Larry A.
Abstract:: A simple matrix method for the analysis of protein circular dichroism (CD) spectra is presented and used to compute the secondary structure of globular proteins in their native and denatured states. The method uses singular value decomposition and generalized inverse algorithms, and a basis set of CD spectra for proteins...

Measurement and interpretation of physical properties of soils

Creator:: Nagpal, Narender Kumar, 1942-
Abstract:: One of many important physical properties that must be known to understand transport phenomena in soils is pore size distribution. Presently the pore size distributions of soils are most commonly obtained from soil water characteristic curves. The soil water characteristic curves are usually obtained by the pressure plate technique. It...

Simulation and field validation of heat and water flow during soil freezing and thawing

Creator:: Pikul, Joseph Lawrence
Abstract:: Freeze/thaw cycles are numerous in agricultural soils of the Pacific Northwest. Potential loss of soil by erosion is high whenever a soil thaws from the surface creating a saturated soil overlying an impermeable frozen layer. Field studies were conducted to investigate the effect of surface residue on soil freezing. Residue...

Effectiveness of index and elite selection methods

Creator:: Douglass, Larry W.
Abstract:: Mice were used to compare the index and elite selection methods for simultaneous selection of four traits. Selection was for litter size, birth weight, weaning weight and post-weaning gain. Progress was evaluated by examining total phenotypic merit. The standard deviations from the cycle mean for the four traits were summed...
