Large volume (1,800 µL) injection HPLC/MS/MS for the quantitative determination of illicit drugs and human urinary biomarkers in municipal wastewater

Creator:: Chiaia Hernandez, Aurea C.
Abstract:: A sensitive, selective, rapid analytical method based on large-volume injection (LVI) liquid chromatography/ tandem mass spectrometry was developed using commercially-available hardware that eliminates the need for either off-line or on-line solid phase extraction. Centrifugation followed by the direct injection of 1,800 µL was used for the quantification of illicit drugs,...

The role of solvent extraction in the chemical characterization of corn stover feedstock

Creator:: Thammasouk, Khamphet
Abstract:: The consequences of extracting com stover feedstock with either 95% ethanol or hot water prior to the chemical analysis of the macrocomponents of that feedstock have been determined. Reports by others have recommended the removal of extraneous substance by solvent extraction prior to chemical analyses (Browning, 1967; TAPPI, 1988). The...

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...

Secrets of the North Staffordshire ceramic recipes : identifying chemical variation and uniformity using an archaeometric approach

Creator:: Hale, Jessica A.
Abstract:: The present thesis chemically examined 174 industrial North Staffordshire pottery fragments from an archaeological context, using Instrumental Neutron Activation Analysis (INAA). In an integrated effort to combine an archaeometric approach with archival research and traditional analysis methods, the purpose of the thesis was to link industrial pottery manufacturers recipes to...

Foam separation of organic and toxic materials in kraft mill effluents

Creator:: Blazier, James Lewis
Abstract:: Because of the organic nature and the natural foaming characteristics of kraft mill effluents, it was decided to investigate the feasibility of using foam separation as a method of treatment. The treatment efficiency was evaluated by BOD and COD reductions as well as the decrease in toxicity to marine life....

A comparison between anthropometric regression equations and hydrostatic weighing for predicting percent body fat of adult males with Down Syndrome

Creator:: Ovalle, Steven E. (Steven Edward)
Abstract:: The purpose of this study was to compare the accuracy of eight anthropometric regression equations with hydrostatic weighing for predicting the percent body fat of adult males with Down Syndrome (DS). Body fat percentages were predicted for 18 adult males with DS. Skinfold, circumference, and bioelectric impedance analysis data were...

An investigation of radioactively contaminated wastewater reclamation plant biosolids

Creator:: Brannan, C. Thomas
Abstract:: Within the last 15 years, wastewater treatment plants have increasingly begun to find radioactive isotopes incorporated in biosolids. Regulations concerning the disposal of radioactive material via sanitary sewer systems were in place since the early 1960's and recently were further restricted. However, the updated regulations would not have prevented certain...

Ecological thresholds, climate extremes, and tree species' distributions across the Pacific coastal United States

Creator:: Lintz, Heather E.
Abstract:: Species' distributions across the landscape are perhaps the least understood yet most conspicuous features of life on earth. Ecologists have long studied species' distributions; yet, many questions remain about why species occur where they do. Such questions persist largely because species' distributions are complex systems with challenging properties like non-linearity,...
