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 …

Reactions Of Tungsten Carbonyl Complexes Containing Diphenylvinylphosphine, George S. Leotsakos

Masters Theses

A new synthetic route for the production of the tungsten carbonyl complex (OC)₅WPPh₂CH₂CH₂PPh₂ has been discovered. It has been found that lithiumdiphenylphosphide reacts with diphenylvinylphosphinepentacarbonyltungsten(0) in tetrahydrofuran to produce upon hydrolysis a good yield of the pentacarbonyl product […]. No evidence for the formation of secondary products was noted nor was there evidence for preferential attack of the carbonyl group by LiPPh₂ to form a carbene complex.

Diphenylvinylphosphinepentacarbonyltungsten(0) (mp 62-64°C), was prepared for the first time by two different methods.

I. Displacement of aniline from anilinepentacarbonyltungsten(0) complex with diphenylvinylphosphine.

II. …

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 …

Establishment Of A District Media Center In Ottawa School District 141, William L. Connelly

Masters Theses

The study consisted primarily of an evaluation on the media program in the Ottawa Elementary School District 141 and recommendations for improving this program. A key element in improving the program is the establishment of a district media center.

The study begins with a review of the literature concerning the role of the media in schools, the value of coordinating media programs, and the role played by district media centers.

The paper explains the categories used in evaluating the schools and examines each in relationship to the established criteria set forth in Standards for Educational Media (Library and Audiovisual) Programs …

The Social History Delinquency Scale, Mary A. Byrne

Masters Theses

Twenty four delinquents from Coles County, Ill. and twenty four non-delinquents were given the Social History Questionnaire (Best and Ericksen, 1973). The two groups were matched on age, sex, and self-reported social status. An item analysis was performed and the questions which differentiated between the delinquents and the nondelinquents were identified. A delinquency subscale was then developed from the 54 significant questions.

Performance On A Drl Schedule As A Function Of Deprivation Levels, Scott E. Memenga

Masters Theses

Twelve male albino rats were divided into three groups that were exposed to a DRL-18 second schedule of reinforcement. Each group was maintained at 70%, 80%, and 90% ad lib weight respectively during 28 days of acqusition training. The 70% ad lib weight group demonstrated continued superior performance over the other two groups after the 10th day. The 80% and 90% groups evidenced little difference between each other until the 20th day when the 80% group showed slightly better performance. Performance was based on the mean time-response efficiency ratios [(reinforced responses/ total responses) + (reinforced responses/ total possible reinforced responses)/ …

The Social History Questionnaire In Relation To Suicide Risk Potential, Edward Ward

Masters Theses

The study of suicide is the study of individuals, each of whom can be considered a unique entity. However, in the course of studying suicide case histories, some demographic variables seem to repeat themselves as differentiating potential suicides from persons who will never attempt or commit suicide. The purpose of this paper is to determine which social history variables correlate significantly with subjects who have made a definite suicide attempt or gesture.

The basic question raised by this thesis was: What factors in a person's social history correlate significantly to an increased probability of having made a suicide attempt or …

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. …
