Pool absorption of gas entrained by a plunging liquid jet

Creator:: Hauxwell, Gerald Dean
Abstract:: A mathematical model was developed to predict the absorption rate of a slightly soluble gas entrained by a plunging liquid jet. The single parameter of the model, the transfer factor, TF, was defined as the summation of the product of the mass transfer coefficient and interfacial area over all the...

Adsorption of Trichoderma reesei CBHI and Thermomonospora fusca E₅ cellulases on model solid surfaces

Creator:: Baker, Carolyn S.
Abstract:: In this research, the interfacial behavior of Trichoderma reesei CBHI and Thermomonospora fusca E₅ cellulases were studied at synthetic surfaces. For this purpose, colloidal silica and polystyrene particles were used to prepare cellulase-particle suspensions that were analyzed by several solution-phase techniques. These included circular dichroism spectroscopy, size exclusion chromatography and...

Assaying the activities of Thermomonospora fusca E₅ and Trichoderma reesei CBHI cellulases bound to polystyrene

Creator:: Kongruang, Sasithorn
Abstract:: In this study the enzymatic activity of adsorbed Thermomonospora fusca E₅ and Trichoderma reesei CBHI cellulases were investigated using fluorescence techniques. In particular, cellulases were allowed to contact hydrophobic polystyrene surfaces under conditions of different solution concentrations, and adsorption times. Each of these variables is known to have a potential...

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...

Interactions between microbial dynamics and transport processes in soils

Creator:: Rockhold, Mark L.
Abstract:: An experimental and numerical modeling investigation was conducted to study interactions between microbial dynamics and transport processes in variably saturated porous media. These interactions are important in a variety of applied problems such as water and wastewater treatment, bioremediation, and oil-field recovery operations. These processes and interactions also have great...

Transport of water and solutes from tile-drained fields in the Willamette Valley, Oregon : A field scale study

Creator:: Warren, Kristina
Abstract:: Tile drainage increases aeration in the root zone of poorly drained soils by accelerating water movement from the subsurface. Water movement is the main agent of chemical transport, either transporting soluble materials directly (e.g., nitrate) or by transporting the soil particles that bind adsorptive compounds (e.g., pesticides). The detection frequency...

Surfactant interactions with recombinant factor VIII at the air/water interface

Creator:: Chu, Liping
Abstract:: The surface tension kin'ti4tnd ste'dy state behavior exhibited by mixtures of selected surfactants with a recombinant Factor VIII (rFVIII) were evaluated with automated interfacial tensiometry. In particular, fresh solutions of rFVIII with different concentrations of Tween 80, sodium dodecylsulfate (SDS), or dodecyltrimethylammonium bromide (DTAB) were prepared and their surface tension...

Henry's Law constants for pollutants from the wood industry in room temperature ionic liquids

Creator:: Wang, Fujun
Abstract:: The emission of organic compounds from wood manufacturing facilities is an important regulatory concern due to their effects on ambient air quality. Control technologies, such as oxidizers and biofiltration, are used to remove organics from air streams; however, most removal technologies have high costs or cause additional negative environmental impact....

Interaction of recombinant factor VIII and the nonionic surfactant Tween 80 at interfaces

Creator:: Joshi, Omkar
Abstract:: The role of the nonionic surfactant Tween 80 on the behavior of the therapeutic recombinant protein Factor VIII (rFVIII) was investigated at solid/liquid and air/water interfaces. In order to provide a model system to compare results obtained for the complicated rFVIII-Tween system, a well-characterized globular protein lysozyme was used. The...
