Experimental approach for the determination of lignin modification by manganese peroxidase

Creator:: Goby, Jeffrey D.
Abstract:: Degradation of lignin to simpler compounds is desirable for removing residual lignin during paper manufacture and accessing biomass carbohydrates for biofuel production, among other purposes. Lignin transformation using enzymes found in white rot fungi, some of nature's most efficient lignin-degrading organisms, offers a more environmentally benign, selective, and possibly less...

Development of a reduced-order dynamic model of a jet-in-crossflow from experimental data

Creator:: Pearen, Keith L.
Abstract:: A reduced-order dynamic model is derived that captures the primary dynamics of a jet-in-crossflow. This is significant progress toward the end goal of reduced order model based closed-loop flow control. The reduced order model is a set of differential equations obtained through the use of snapshot based Proper Orthogonal Decomposition...

Physiological response of Nitrosomonas europaea to oxytetracycline, chromium, and silver

Creator:: Schaerer, Morgan A.
Abstract:: Nitrosomonas europaea carries out the first step in the biological nitrogen removal process in wastewater treatment by oxidizing ammonia to nitrite. It has been shown to be sensitive to a wide range of contaminants. The antibiotic oxytetracycline and the heavy metals chromium and silver have been found in wastewater influent....

Effects of doping, cation stoichiometry, and the processing conditions on the dielectric properties of high-K CaCu₃Ti₄O₁₂ ceramics

Creator:: Kwon, Seunghwa
Abstract:: Since its discovery, the anomalous dielectric behavior of CaCu₃Ti₄O₁₂ (CCTO) has drawn a great deal of attention for many possible applications in electronic devices. The origin of the giant dielectric constant in CCTO was explained via an internal barrier layer capacitor model, and it has been reported that the dielectric...

The effect of elevated temperature on mechanical behavior of structural wood and wood-based composites

Creator:: Sinha, Arijit
Abstract:: Engineers, in practice, are often faced with the challenge of evaluating a fire-damaged structure and developing a rehabilitation and retrofit plan. In order to decide on a rehabilitation and retrofit plan, information on thermal degradation of building materials and connections are vital. A critical knowledge gap exists in terms of...

Further Development of MPM and its Applications in Modeling Wood-Adhesive Bonds

Creator:: Hammerquist, Chad C.
Abstract:: This work is a culmination of a series of published works related to the use of the Material Point Method (MPM) in modeling wood adhesive bonds. The use of wood as construction material has the potential to play a small role in the solution to the current CO2 and climate...

Commercialization potential of viscoelastic thermal compressed (VTC) wood

Creator:: Macias, Natalie R.
Abstract:: The increasing demand for forest products and restricted use of natural forests has resulted in a shortage of high-strength wood fiber. The area covered by plantation forests is steadily rising, but the fiber produced by these forests is often unsuitable for high-strength applications. One attempt to combat this problem is...

Sediment reservoir dynamics on steepland valley floors : influence of network structure and effects of inherited ages

Creator:: Frueh, Walter Terry
Abstract:: Sediment deposit ages inferred from radiocarbon dating of stream bank material were used to estimate residence times of valley-floor deposits in headwater valleys of the Oregon Coast Range, USA. Inherited ages of radiocarbon-dated material, i.e., time between carbon fixation in wood and its incorporation in a sediment deposit, can result...
Resource Type:: Masters Thesis
Full Text:: fixation in wood and its incorporation in a sediment deposit, can result in over-estimation of the ages

Ecosystem Photosynthesis and Forest-Atmosphere Interactions Inferred from Carbonyl Sulfide

Creator:: Rastogi, Bharat
Abstract:: An increase in anthropogenic activities since the industrial revolution, primarily due to burning of fossil fuels and changes in land cover, has resulted in a steady increase in the global mean atmospheric CO2 concentrations. While there is unequivocal scientific evidence on global warming and its multidimensional impacts on natural and...

A survey and analysis of the attitudes of non-negro parents in selected Portland elementary schools

Creator:: Farrell, Bernard Joseph
Abstract:: The study of parent attitudes in Portland, Oregon, elementary schools was designed to accomplish three purposes: (1) To identify the attitudes of Non-Negro parents toward integration of Negroes into the schools and community, (2) To measure the effects of socioeconomic classes (low, middle, upper), of schools (control versus transfer), and...
