A Histochemical Study Of Tooth Development In The Chinese Hamster (Cricetulus Griseus), Robert B. Daszkiewicz

Masters Theses

The normal morphological development of the Chinese hamster (Cricetulus griseus) during the last week of gestation was studied. A review of the literature reveals no distinct study of tooth development in this species. An identical gestation period is found in the mouse (Mus musculus) making direct comparison between the embryos of the same age of the two species feasible. During this investigation, it was found that morphological tooth development in the Chinese hamster lagged behind that of the mouse by about 2 days. On day 14 of gestation in the Chinese hamster, the oral epithelium is …

Utilization Of Waste Heat From The University Of Missouri Research Reactor., Anek Punyakumleard

Masters Theses

"An analysis has been conducted to determine the economic as well as technical feasibility of using waste heat from the University of Missouri Research Reactor (MURR) to heat the reactor containment building and the associated laboratory building.

Several methods of waste heat utilization were reviewed, including open field agriculture, animal shelter heating, aquaculture, waste water treatment, and space heating. Based on this review, it was concluded that several of these waste heat utilization methods are feasible for the MURR. However, the most practical means of utilizing the MURR waste heat appears to be for space heating in the reactor containment …

The Effects Of Residual Chlorine On Selected Microflora Of Kickapoo And Cassell Creek, James A. Mcgaughey

Masters Theses

The survival of fecal coliforms, fecal streptococci, and heterotrophs after exposure to chlorine were compared in receiving waters of the Mattoon and Charleston, Illinois waste treatment facilities employing membrane filter techniques and Standard Plate Counts. Water samples were taken from receiving waters upstream from the treatment plant, from secondary effluent and chlorinated secondary effluent within the plant, and from downstream receiving waters. Stream flow contribution and plant effluent contribution required the calculation of dilution factors to determine expected numbers of the various microflora found downstream assuming no residual chlorine effect. Total chlorine concentration was measured by amperometric titration at the …

Utilization Of Heat Sensitivity In Crotalidae, James Cordrey Miller

Masters Theses

Specimens of five genera of snakes (Crotalus, Agkistrodon, Bitis, Epicrates, and Elaphe) were tested for use of thermal cues in food selection. Results indicate that pit vipers (Crotalus and Agkistrodon) and boas (Epicrates) utilize thermal radiation in selection of food. It was also indicated that Crotalus (rattlesnakes) do not invariably show a reflexive strike before food is investigated or ingested.

A Study Of Symbiosis Involving The Fish-Eating Bat (Myotis Vivesi), The Least Petrel (Halocyptera Microsoma), The Black Petrel (Oceanodroma Melania), And The Lizard (Cnemidophorus Tigris), Joel King

Masters Theses

A field study was conducted on Partida Island in the Gulf of Mexico on the dates May 26 through July 26, 1977, inclusive.

Field observations were made of the lizard (Cnemidophorus tigris) preying on eggs and hatchlings of the least petrel (Halocyptena microsoma), and the black petrel (Oceanodroma melania). The petrels roost among rock slides with the fish-eating bat (Myotis vivesi).

In 24 trials of experimental boxes with lizards, bats, and petrels as subjects, 16 trials resulted in aggression of bats to lizards.

A symbiosis is postulated between bats and petrels.

An Internship In Administration, Jerry Joe Newell

Masters Theses

The Field Study consisted of an internship in administration. An internship in administration in the field of vocational education appeared most beneficial to interests and objectives of the writer. The internship was served under the supervision of the director of vocational education and athletics. Activities in which the writer was involved within the athletic department offered limited value towards administrative experience beyond general supervision at athletic events. These activities were not a concern of the internship, since they would not normally be responsibilities of the vocational director.

A considerable part of the internship involved the routine management of the vocational …

One Artist’S Experimental Approach To Sculpture, John J. Smith Iv

Masters Theses

This paper is intended to reflect the creative sensibilities of one artist-scientist as he experiments with media and his perceptions of nature as an approach to growth. His philosophy revolves around the relationship of his experience, his natural instinctive sensibilities, their affection upon his intuition, and the resulting creative process. The stimuli for the process are found in the natural realm around him whether perceived scientifically or artistically. Due to the intrinsic nature of the creative phenomenon, it is very difficult for the artist to separate the scientific and artistic modes from the naturalistic or experiential stimuli. So he goes …

The Effects Of Sulphur Dioxide On Selected Hepatics, Steven L. Gatchel

Masters Theses

Extensive studies have been reported on the air pollutant sulphur dioxide (SO₂), and its effects on vascular and nonvascular plants. It has been shown to interrupt normal physiology, metabolism, reproduction, and alter the plant’s morphology.

Of the cryptogams, lichens have been extensively used as biological indicators of air pollution. More recently, bryophytes have been shown to be as sensitive to contaminates as lichens, and may exhibit responses to the pollutant similar to those of vascular and nonvascular plants. The threshold sensitivity of these cryptogams is about 0.5 ppm over a 12 hour period. However no study to date …

The Cirsium Altissimum - Discolor Complex In Illinois, Dennis R. Bischoff

Masters Theses

Cirsium altissimum, C. discolor and suspected hybrids used in this study were collected during September 1977 from three locations in east central Illinois. All were combined for subsequent taking of data because the study dealt with incidence of hybridization and morphological discriminators rather than degrees and directions of introgression. Ten possible discriminators were chosen by examination of herbarium specimens of parental plants: I, Involucre width; II, Involucre height; III, Pubescence of upper leaf surface; IV, Angle of departure of main veins from the midrib; V, Number of spines per cm along the margin; VI, Length of indurate portion of …

Epizoic Protozoa Of Planktonic Copepoda And Cladocera From A Small Eutrophic Lake, And Their Possible Use As Indicators Of Organic Water Pollution, Michael Stevens Henebry

Masters Theses

The epizoic protozoa of planktonic copepoda and cladocera from a eutrophic lake (Ashmore Lake, Coles County, Illinois) were studied over a 13-week period in the summer and fall of 1975. All organisms were collected with a 125 micron mesh plankton net. Epizoans (all peritrichs and suctorians) were hosted by three of four species of copepods and four of the ten species of cladocerans. The percentage of total organisms hosting epizoans varied significantly (0.001 alpha level) by month, but averaged 11.6 percent. This high occurrence of epizoans was thought to be related to the highly-eutrophic conditions existing in the lake. If …
