Dynamic properties of naturally frozen ice

Creator:: Hammer, Theodore A.
Abstract:: In recognition of the need to determine dynamic properties of naturally frozen materials, a research project was conducted to measure the dynamic properties (dynamic moduli and damping ratio) of naturally frozen wedge ice samples obtained from the Fairbanks, Alaska area. Cyclic triaxial and resonant column test systems were employed to...

Structural analysis of symmetrical penstock bifurcations by the finite element method

Creator:: Shugar, T. A.
Abstract:: A need has existed for an in-depth structural analysis of penstock bifurcations because they form an integral part of hydroelectric power plants. Their geometrical complexity has prevented classical structural analysis from providing an accurate and overall picture of the stresses in the structure. Digital computers and the development of finite...

Microcosm studies of bioaugmentation with a butane-utilizing mixed culture : microbial community structure and 1,1-DCE cometabolism

Creator:: Lim, Hee Kyung
Abstract:: The 1,1-dichloroethene (1,1-DCE) cometabolic transformation abilities of indigenous and bioaugmented microorganisms were compared in microcosms constructed with groundwater and aquifer solids from the Moffett Field site, CA. Microbial community structure in the microcosms and possible community shifts due to 1,1-DCE transformation stress was evaluated by terminal restriction fragment length polymorphism...

Molecular analysis of bacterial community dynamics during bioaugmentation studies in a soil column and at a field test site

Creator:: Li, Jun
Abstract:: 1,1,1-Tricholorethane (1,1,1-TCA), a widely used industrial solvents, is one of the most common subsurface contaminants. Transformation processes in the subsurface can result in the production of 1,1-dichioroethane (1,1-DCA) and 1,1- dichioroethene (l,1-DCE) from 1,1,1-TCA contamination, resulting in plumes of mixed chlorinated aliphatic hydrocarbons (CAHs). A butane-utilizing microorganism, strain 1 83BP,...

Relationships between seasonal suspended sediment behavior and reservoir turbidity

Creator:: Conner, Dan Alan
Abstract:: The causes of turbidity in impounded and released reservoir water are studied. Seven Willamette Basin reservoirs are compared to isolate watershed and reservoir characteristics which produce variations in turbidity. Of the seven, Hills Creek Reservoir is examined in detail. Particular features of the basin and impoundment are studied to isolate...

Aqueous-organic partition coefficients for Rn-222 and their application to Radon analysis by liquid scintillation methods

Creator:: Cantaloub, Michael G.
Abstract:: A method is described for determining the partition coefficient, K, for radon gas distributed between an aqueous phase and an organic solvent. The method uses sequential extractions of radon into equal volume aliquots of organic solvent. The radon-laden organic liquid is then counted on a liquid scintillation analyzer with alpha-beta...

Interstitial fluid mixing in estuarine benthic sediments

Creator:: Boyce, Allen R.
Abstract:: A method of measuring interstitial fluid mixing rates for evaluation of exchange between pore water of estuarine benthic sediments and the overlying water in a bay is presented. Pore water movement is monitored by reducing conductivity of the interstitial fluid within a zone of the benthic sediment to a depth...
