Response Of A Nitrifying Biofilm To Copper, Denise Moldroski Mott

Masters Theses

In pure cultures of Nitrosomonas, copper is known to cause a stimulation of nitrification at low levels (≤ 0.03 mg Cu⁺²/1) and an inhibition affect at higher levels (≥ 0.05 mg Cu⁺²/1). Nitrifying activated sludges are much more tolerant of copper showing only 75% inhibition at 150mg Cu⁺²/1. The purpose of this paper was to determine the copper sensitivity of a nitrifying biofilm grown in a continuous flow trickling filter system.

A continuous flow trickling filter system was built using limestone chips for the biofilm substrate. The biofilm was established from secondary effluent. …

Winter Concentration Areas Of White-Tailed Deer (Odocoileus Virginianus) In Illinois: A Discriminant Analysis, Paul A. Brewer

Masters Theses

Two discriminant models were derived from 40 variables measured in 12 white-tailed deer (Odocoileus virginianus) winter concentration areas and 12 non-concentration areas in east-central Illinois. The first model correctly classified 100% of these areas based on area of refuge, area of upland hardwoods with <50% crown closure, area of bottomland forest with <50% crown closure, distance of unimproved roads, and total topographic relief. This model was tested on 6 winter concentration areas in west-central Illinois and 6 winter concentration areas in northern Illinois. The first discriminant model correctly classified 91.7% of these areas.

The second model originated from the same set of variables, however the refuge area variable was removed in an attempt to classify winter concentration areas without knowledge of refuge areas. This model correctly classified 91.7% of sites in east-central Illinois, and 75% of the areas in west-central and northern Illinois.

The Law And Mark Twain, Jeff Andrew Weigel

Masters Theses

Varying concepts of law are an essential part in many of Mark Twain's works. Twain's position as an observer and critic of society is often reflected by the way he represents law and justice in his stories. His dislike of injustice and cruelty caused him to focus on these "legal" problems as a way of revealing and attacking various injustices in society. My thesis examines Twain's perception of law as he exposes it in Roughing It, Pudd'nhead Wilson, The Prince and the Pauper, and A Connecticut Yankee in King Arthur's Court. The general objective of my …

Mark Twain's Confidence Men, Sharon K. Scruton

Masters Theses

In Mark Twain's literature the confidence man has special talents, but he is also subject to human failings. Through the characters of Huck Finn and Hank Morgan (A Connecticut Yankee in King Arthur's Court) Twain exposes the traps into which a con artist, as a creative talent, can fall. Twain knows these traps, both from experience and from fears of what the future holds. Hank Morgan becomes an extension of Huckleberry Finn. He is a figure who, as he progresses, leaves the best talent of a con artist behind--the talent of instinct. The natural abilities of insight and …

"Failed Love" In The Drama Of Edward Albee, Steven Leonard Long

Masters Theses

The plays of Edward Albee are frequently examinations of characters who are unable to love or to be loved. A central and recurring conflict which runs through many of Albee's plays is the conflict which stems from the lack of success which the characters often experience as they strive to find love. The uncertainty and ambiguity which surround the abstraction called "love" leave the characters with feelings of unhappiness, frustration, fear, self-hatred, and despondency. Though the individuals in Albee's plays are aware that love is the ingredient which is missing from their lives, none knows how to go about alleviating …
