Use Of Fishes And Macroinvertebrates In The Assessment Of Water Quality In An Illinois Stream Receiving Sewage Effluents, Robert George Mosher

Masters Theses

Kickapoo Creek is a medium sized, warm water stream located in the central part of Coles County, Illinois. The creek is the receiving stream for the sewage effluent of the cities of Mattoon and Charleston which recently began treating sewage to the tertiary level. In 1967-70, the fish population of the creek was intensively surveyed at a time when a less advanced method of sewage treatment was employed. This study provided a baseline of information from which a portion of the present study is founded.

Fish were collected from 5 sampling stations utilizing capture techniques comparable with those used in …

The Influence Of Food On Induction Of Males In Daphnia Pulex, Paul Henry Schreuder

Masters Theses

Introduction

Daphnia pulex Leydig (Crustacea, Cladocera) is a common component of the zooplankton of freshwater lakes and ponds. Its importance in the aquatic trophic structure as food for small fish has long been recognized.

Typical populations of daphnia consist almost exclusively of females. Under favorable conditions this situation is perpetuated by parthenogenetic reproduction. Eggs produced in this manner are referred to as parthenogenetic or summer eggs. When stressed by falling temperatures, drought, overpopulation, or starvation, populations shift to sexual.reproduction. Parthenogenetic eggs are produced which develop into males. Other eggs known as ephippial or winter eggs are also produced, which after …

The Lithic Assemblage Of The Hacklander Site, Allegan County, Michigan, Jerrel H. Sorensen

Masters Theses

Introduction

Orientation

In A History of American Archaeology Willey and Sabloff (1974) outline the development of archaeological method and theory in the Western Hemisphere. The authors defined 5 periods through which they traced advances in archaeology from the time Europe first discovered the New World. Each other these periods is characterized by certain attitudes and orientations toward archaeological data. Old ideas changed as new information, new tools of discovery, and new ways of interpretation and explanation transformed archaeology into what it is today.

Archaeologists are now in the Explanatory Period (Willey and Sabloff 1974:178). This period's theoretical orientation can be …

Structural Effects On Micellar Catalyzed Reaction Of Hydroxamic Acids, Nop Utrapiromsuk

Masters Theses

Introduction

For many years scientists have tried to find a model which resembles a biological system, so that they can use this model for studying biological systems in human and in living organisms. Micelle systems provide the environment to mimic enzyme systems to some degree.¹

Soaps and detergents generate micelles. Soaps and detergents have been used as cleansing agents for a long time. Their cleansing properties are related to micelle formation. Actually, soap is simply a mixture of sodium salts of long chain fatty acids, R-COO^- Na⁺, and some detergents are general sodium salts of straight …

Vegetational Communities On An Abandoned Farm In Van Buren County, Michigan, Larry G. Visser

Masters Theses

Introduction

Several studies have been made of xeric forests in southern Michigan which have developed through secondary succession following the cutting of the presettlement vegetation. Brewer et al. (1973) described such an area in Allegan County, Michigan which was dominated by presettlement pine and is now dominated by oak. The oak forests of the Harvey Ott Preserve in Calhoun County, Michigan have been described by Catana (1967). Studies of the oak forests in the Haven Hill area in southeastern Michigan have been made by Thompson (1953). In addition to these studies of xeric forests in southern Michigan, extensive studies of …

Shallow Water High-Magnesium Calcite Mud Production And Dispersal, St. Croix, U.S. Virgin Islands, Jonathan A. Fuller

Masters Theses

Boiler Bay, on the northeast coast of St. Croix, is 200 m wide, 800 m long, and about 3-5 m. deep. The hay is separated from the open Caribbean by a barrier reef. Winds from the east drive currents westward across a narrow carbonate platform (where they entrain platform-derived carbonate mud) and into the east end of the bay. Longshore currents continue westward through the bay, and the entrained platform- derived suspended load is combined with bay-produced carbonate mud and swept northwestward off the platform after passing through a 6 km complex of bays along the northeastern shore. The suspended …

Amperometric Determination Of Chemical Oxygen Demand, Catherine Eckert Hutchins

Masters Theses

A method is described for measuring the low level --5 to 50 ppm-- chemical oxygen demand (COD) of water samples by amperometric titration. The method involves digestion of the sample with potassium dichromate in a 50% sulfuric acid solution using one-fifth the reagents and sample required for the standard COD method. This is followed by an amperometric titration using a standard ferrous ammonium sulfate solution and employing a rotating platinum electrode in a three-electrode potentiostatic system. The titration is carried out at a potential of +0.80 volts versus a saturated calomel electrode, thus eliminating the need for O₂ purging …

Investigations Of Possible Allelopathic Effects Of Lycopodium Flabelliforme (Fern.) Blanch., Joan Macuszek

Masters Theses

Lycopodium flabelliforme (Fern.) Blanch. sporophytes were collected from a colony west of Flat Rock in Crawford County, Illinois. The material was either ground to a coarse grade using a Wiley Mill (grindate), left whole and untreated (fresh) or water extracted with a Waring blender (extract). The effect of the sporophyte material was tested on the germination of seeds and on the growth of seedlings of Raphnus sativa L. Sporophytes subjected to the grindate treatment showed the most inhibitory effects. It was shown that the alledged inhibitory substance was heat stable and able to be concentrated. Using column chromatography, at 37.7°C, …

Ergosterol Effect On The Desaturation Of 14c-Cis-Vaccenate In Tetrahymena, Tiee-Chyau Miin

Masters Theses

Supplement of ergosterol to the growth medium of the ciliated protozoan Tetrahymena pyriformis W leads to incorporation of the foreign sterol within cell membranes and suppression of synthesis of the native sterol-like compound tetrahymanol, as well as to changes in the fatty acid compositions of several major classes of membrane lipid. Alteration of fatty acid composition is thought to represent a regulatory mechanism whereby optimum membrane fluidity is maintained when the slightly dissimilar foreign sterol is added into the phospholipid bilayer of the membranes.

The present study, using several different conditions of growth temperature, substrate concentrations and incubation time, and …

The various duties performed by the intern and the situations he encountered are recorded in …

Handbook For The Champaign County Youth Detention Center, James A. Talley Jr.

Masters Theses

This handbook was developed to serve the needs of the Champaign County Youth Detention Center and interested community members. It is also designed to serve as a guideline for future handbooks at the center and for other agencies which may require such a handbook. This handbook should eliminate any confusion concerning regulations and policy of the center and prove to be satisfactory replacement for single sheet information which was formerly used.

There was an apparent need for this handbook to replace the intake folder and thereby provide a more useful and meaningful method of transmitting vitally important information to concerned …

A Pilot Study Of A Sex Education Program In A Sheltered Workshop Using A Cognitive-Behavioral Model Based On Rational Emotive Therapy, Jacqueline A. Rieck, Thomas E. Frederick

Masters Theses

This pilot study was developed to teach people with mental retardation about their own sexuality, appropriate community behaviors, and to develop within them a basic sense of responsibility for their own actions. Problems in social/sexual behaviors have been consistently quoted as reasons for high recidivism rates, as well as difficulties in community living, vocational placement, and other generalized stereotypes about mental retardation. Often the public remains uninformed about, does not recognize, and/or feels that sexual rights for people with any mental differences should not exist. Additionally, when any form of sexuality was expressed by such people it resulted in shock …

Feeding Habits And Behavior Of The Whiptail Lizard Cnemidophorus Tigris On Partida Island, Patrick Alan Malone

Masters Theses

The feeding habits of the whiptail lizard Cnemidophorus tigris were studied from May 25 until July 23, 1977 on the Partida Island in the Gulf of California. Analysis of the stomach contents of 91 lizards revealed that during this period the eggs and young of the least and black petrel are a primary food source while tenebrionid beetles become a major food source after bird products become unavailable.

Interactions In Lambdoid Bacteriophage Populations, Bruce Edward Mitchell

Masters Theses

The lambdoid bacteriophages are ideal subjects for the study of populational interactions at the molecular level because they do not mutually exclude one another in mixed infection of the same host cell. Previous work done in this laboratory using the lambdoid phage pairs λ-434 hy mi and λ-∅80 have demonstrated a density-dependent reduction in progeny yield per infected cell (burst size) as a function of increasing multiplicity of infection (m.o.i.). The λ cI gene which codes for the repress or molecule has been demonstrated to be the cause of the interaction in the λ-434 hy mi phage pair. …

The Structure And Fate Of Germinal Plasm In The Asiatic Fire-Bellied Frog, Bombina Orientalis (Anura-Discoglossidae), Ted W. Odom

Masters Theses

Lehman's polychrome stain was used to follow the fate of germinal plasm in early development of Bombina orientalis embryos. Islets of germinal plasm approximately 6 um in diameter were observed in the vegetal pole region of the 2-cell embryo. By the 4-cell stage, some of these islets had coalesced to form larger ones so that two size classes of islets were present (approximately 7.5 and 19.5 um in diameter).

As cleavage continued to the 16-cell stage, the islets were moved further up the cleavage furrow and were always observed to remain in close association with the cleavage membrane. The islets …
