The Evolution Of The Gull Lake Community, 1900-1975, Mary E. Penzkofer

Masters Theses

Introduction and Conceptual Framework

The Purpose

Kalamazoo County, like much of southern Michigan in which it is located, is the locale for a unique type of rural settlement - the lakeshore dormitory community. These communities, located at inland lakes which were popular summer resorts in the early years of this century, have experienced stages of development unlike those of any other type of rural community. These stages and the historical events connected with them, have undoubtedly left visible impressions on the character of the present communities.

Computational Models Of Learning., Kenneth Jesse Marse

Masters Theses

"An investigation is made into the use of techniques which would normally be described as learning if encountered in a human being. A literature review of several subject areas including game-playing computer programs, automatic control systems, pattern recognition methods, and biological modeling is performed, with the purpose of extracting and examining those processes which exhibit learning. A general model of the type of learning most widely utilized in these areas is constructed and used to compare and contrast specific models which describe the learning techniques employed. Some specific models which do not exhibit learning as described by the general model …

A Faunal Study Of Illinois Silphidae (Coleoptera), Brian Baldwin

Masters Theses

A faunal study of the family Silphidae in Illinois was made through examination of over 1400 specimens. A brief history of the taxonomy of the family and a description of silphid ecology was presented. Keys to the tribes, genera, and species of adult Silphidae occurring in Illinois were divised. Four genera and sixteen species of silphids are described, supplemented with drawings and distribution maps.

Fungicides And Insecticides For Control Of Rose Pests, Paul F. Webb

Masters Theses

The author was requested by a representative of the Ortho Chemical Company to test various fungicides and insecticides on hybrid tea roses.

Roses are one of the most time consuming and most difficult ornamentals to manage due to several diseases and insects that attack them. Two of the first and foremost skills that the author had to acquire were the proper planting and the subsequent care of roses.

The purpose of the research project was to compare the effectiveness of experimental products with presently available fungicides and insecticides. Before new chemicals can be marketed much data must be collected to …

A Statistical Approach To The Study Of The Ecosystems Of Seven Ponds In East-Central Illinois, Gregory Lee Orr

Masters Theses

Gross primary productivity, heterotrophic bacterial numbers, and net phytoplankton densities of seven ponds in Coles County, Illinois, were studied in relation to physical, chemical, and biological habitat variables (light intensity and duration, turbidity, water temperature, pH, dissolved oxygen, sulfur, nitrogen, phosphorus, production, bacteria, and phytoplankton). Ten observations were made for each pond (except where otherwise noted) from 17 June through 25 August 1974. Stepwise multiple linear regression analyses of the data were used in order to determine those environmental factors which were important in predicting (i.e., significantly correlated with) bacterial and phytoplankton densities, and production. A multiple linear regression equation …

Treflan And The Oxygen Consumption Of Green Sunfish (Lepomis Cyanellus), Barbara Jo Warner

Masters Theses

Oxygen consumption rates of 51 green sunfish (Lepomis cyanellus, Rafinesque) were monitored over five hours exposure to Treflan E.C. concentrations of 0, 0.32, 0.56, 1.0, and 2.0 ppm. There was a great variation in the responses of the fish at each concentration; and Student's t-tests revealed no significant differences. However, graphs of the mean hourly oxygen consumption rates showed certain trends. During the fifth hour of exposure, there appears to be an acclimation to the Treflan at concentrations of 0.32 and 0.56 ppm; but no such acclimation at the higher concentrations of 1.0 and 2.0 ppm. Hourly oxygen …

Parasites Of Channel Catfish In Illinois Hatcheries, Charles Dale Meryman

Masters Theses

Ninety channel catfish (Ictalurus punctatus) were trapped during September 1973 through April 1974 at three hatcheries located at Worden, Centralia, and Kinmundy, Illinois. All were examined for parasites and 87 were parasitized. The trematodes Azygia angusticauda and Neascus sp. were found in the gastrointestinal system and Cleidodiscus floridanus and Dactylogyrus sp. were attached to the gills. Five cestode genera, including Bothriocephalus sp., Corallobothrium giganteum, Eubothrium sp., Haplobothrium sp., and Proteocephalus ambloplitis were present. Rhabdochona sp. was the only nematode found. Protozoans; Costia sp., Myxobolus sp., Scyphidia macropodia and Trichodina discoidea and one kind of glochidium were observed. …

A Study Of Trace Organic Emissions In Mining And Milling Wastewaters In The New Lead Belt Of Southeastern Missouri., Alan James Callier

Masters Theses

"The primary objective of this study was to evaluate the trace organic contributions by two lead and zinc mining and milling operations in Southeastern Missouri. A secondary objective was to evaluate a reverse osmosis-solvent extraction method for use in recovering trace organics.

Trace organics were recovered in the first phase of the study following procedures as outlined by the American Society of Testing and Materials (ASTM), with chloroform and benzene being used as the solvents. The data indicated that the milling waste contained a larger concentration of trace organics than the excess mine water. Furthermore, it was shown that recycling …

Denitrification Of A Synthetic Waste With A Submerged Filter, Dominic Joseph Grana

Masters Theses

"The facultative anaerobic submerged filter is a plug flow, packed bed, column type reactor in which the facultative microorganisms responsible for nitrate reduction are attached to the filter media. The objective of this study was to evaluate filter performance and the kinetic equations of the process under variable conditions of flow rate, nitrate nitrogen concentration, and organic loading.

Two 0.5 cu ft (14.25 1) laboratory filters were operated for 144 days at 35°C using a synthetic waste as the substrate. Filter media consisted of smooth quartzite stone, 1 to 1.5 in. (2.54-3.82 cm) in diameter. Each filter had a porosity …

An Organizational Structure For A Highway Agency., Frank L. Carroll

Masters Theses

"Highway agencies in the past have been organized to give primary consideration to economic factors. Th e National Environmental Policy Act of 1969 changed this concept by requiring all states to reevaluate their highway organizations in order to ensure that social and environmental factors, as well as economic factors, are considered.

Various state highway organizations are analyzed to determine the way in which consideration is given to the social, economic and environmental effects of design, and a model organizational structure for a highway agency is developed.

Because considerable difference exists in the ways in which the states have approached the …

Effects Of Colloidal Materials And Polyelectrolytes On Carbon Adsorption In Aqueous Solution., Jack Taylor Garrett Jr.

Masters Theses

"The purpose of this study was to investigate the effect of certain colloidal materials and long-chain polyelectrolytes on the adsorption efficiency of some selected activated carbons which were manufactured from both coal-based and lignite-based materials. Phenol was used as the adsorbate to determine the adsorption efficiency.

At the beginning of the study, four brands of activated carbon (i.e. Filtrasorb 400, Darco, Norit, and Witco 256) were tried, based on the preliminary adsorption data, two activated carbons were subsequently selected for use throughout the entire study. These were Calgon's Filtrasorb 400 and American Norit's Norit activated carbons. The former represents a …

Wastewater Treatment With Activated Carbon., Chia-Soui Joseph Lu

Masters Theses

"The objectives of this study was to determine the capabilities of selected types of activated carbon as an adsorbent for the removal of organic materials from municipal wastewater and sludges. The organic sources included primary and secondary clarifier effluent, blended sludge, and digester supernatant. Two other organic sources, glucose and alanine, were also examined to determine their removal from aqueous solution by activated carbon adsorption.

The organic impurities, in terms of chemical oxygen demand (COD), were reduced from 68 mg/1 in the primary effluent and 35 mg/1 in the secondary clarifier effluent to approximately 15 mg/1 for both. However, the …

Homing Studies Of Bank Swallows In Eastern Illinois, Jennifer Eileen Hagerstrom

Masters Theses

A series of homing experiments using 39 color-marked Bank Swallows (Riparia riparia) were carried out in eastern Illinois during the summer of 1975. The swallow colony was located four km east-northeast of Charleston, Illinois at the Charleston Stone Quarry. Eight release sites were located in the four compass directions from the home colony at distances of 14.4 to 32.3 km away.

The colony was approached before dawn and swallows were captured using tube traps. Birds were color-marked, banded, and taken in individual bags to the release site by automobile. Cloud cover, wind velocity, wind direction, and orientation behavior …
