Decomposition of cattail and bulrush plant parts in a constructed wetland treating pulp mill effluent

Creator:: Walz, Anita
Abstract:: Dried cattail and bulrush plant pieces in mesh bags were incubated in the constructed wetland treating Pope & Talbot pulp mill effluent. Two ponds planted with each species and two depth ranges in each pond were chosen, to determine decomposition rates. Bags were withdrawn and analyzed at five time points...

Surface tension kinetics of the wild type and four synthetic, structural stability mutants of bacteriophage T4 lysozyme at the air-water interface

Creator:: Wang, Jun, 1968-
Abstract:: Surface tension kinetics exhibited by selected stability mutants of T4 lysozyme at the air-water interface were monitored with DuNoüy tensiometry. Mutant lysozymes were produced by substitution of isoleucine at position 3 with cysteine, leucine, tryptophan and glycine. Each substitution resulted in an altered structural stability quantified by a change in...

Use of pore-scale network to model three-phase flow in a bedded unsaturated zone

Creator:: Zhang, Wenqian
Abstract:: Contamination of ground water by non-aqueous phase liquids (NAPLs) has received increasing attention. The most common approach to numerical modeling of NAPL movement through the unsaturated zone is the use of the finite difference or finite element methods to solve a set of partial differential equations derived from Darcy's law...

Influence of extractives on the chemical analysis of switchgrass

Creator:: Tandjo, Djuhartini
Abstract:: This thesis summarizes an investigation into the need for removing extractives from herbaceous biomass feedstocks prior to their chemical characterization. Switchgrass (Panicum virgatum), was used in this study as a representative herbaceous biomass feedstock. The influence of extractives on the chemical analysis of switchgrass was done by comparing the composition...

Evaluation of physical and thermal methods to support nonlinear cost optimization models of surimi seafood

Creator:: Hsü, Cheng-kuang
Abstract:: Optimization programming techniques were applied to develop the least cost formulations for Pacific whiting surimi-based seafood (PWSBS). To develop the quality constraint functions, texture and color of whiting surimi gels were determined by torsion test and colorimeter, respectively. Whiting surimi gels were produced by heating at 90°C for 15 min....

Saccharification and fermentation of lignocellulosic biomass using Trichoderma reesei cellulases and Saccharomyces cerevisiae

Creator:: Chung, Yun-Chin
Abstract:: The efficiency of cellulose hydrolysis under straight saccharification and simultaneous saccharification and fermentation (SSF) conditions was evaluated using three lignocellulosic materials (switchgrass, cornstover, and poplar), which had been pretreated with dilute sulfuric acid under conditions which optimized xylose concentrations in the prehydrolysate liquid. Yields of glucose, cellobiose and ethanol obtained...

Degree and scale of interactions among chiefdoms during the pre-Hispanic late period in northern Highland Ecuador (AD 1250-1525)

Creator:: Yanchar, Kaitlin C.
Abstract:: During the Late Pre-Hispanic period, settlements in Northern Highland Ecuador were organized under a number of chiefdoms. While a basic hierarchical political system is described in the ethnohistoric literature, the nature of the interactions between specific settlements has remained unknown. This study utilizes two methods for describing the degree and...
