Studies On The Effects Of Toxic Materials On The Respiration Rate Of Tubificidae, Richard A. Sikora

Masters Theses

A study was made to determine the effect of lead, nickel and pentachlorophenol, at varying pH levels, on the respiration rate of this family of aquatic oligochaetes. Respiration was measured as the ul. of oxygen consumer per mg. of live tissue per hour of exposure.

Worms were found to decrease their rate of respiration in the presence of lead nitrate. This was demonstrated at three pH levels: 6.5, 7.5 and 8.5. It was concluded that this drop was due to the action of lead on the enzymes of the metabolic systems and on the characteristic of lead which stimulates the …

Some Effects Of Nickel On The Microbial Population Of Activated Sludge, Virgil Eugene Carr

Masters Theses

"The purpose of this investigation was to study the effects of nickel on the microbial population of activated sludge, to establish a relationship between effluent quality and changes in microbial population, and to determine the fate of nickel applied. Five one liter fill and draw activated sludge units were fed settled domestic sewage and received constant daily nickel doses of 1-10 mg/l, and a 50 mg/l slug dose applied after 27-30 days of operation. The parameters used were the chemical oxygen demand (COD) of the effluent and membrane filtered effluent, mixed liquor and effluent total suspended solids, mixed liquor volatile …

Quality Of Surface And Subsurface Water In A Missouri Carbonate Karst Terrain (Dry Fork, Norman, And Benton Creek Watersheds), James Chi Huang

Masters Theses

"Little is known about the effect of carbonate karst terrain on water quality in the United States. Karst topography occurs over a large portion of Missouri and over a significant part of other midwestern states. The objectives of this study were the determination of the quality of surface and subsurface water in carbonate karst terrain and the investigation and evaluation of the effect of rainfall and runoff on water quality in the Meramec Spring area, east of Rolla, Missouri, during both the dry and wet seasons over the period of one year. Water samples were collected at a large number …

The Relation Of Heat Transfer To Mass Transfer In Vaporization Through Porous Membranes., Chung-Liang Yeh

Masters Theses

"The object of this investigation was to study the mass and heat transport phenomena through porous, water-repellent membranes. The investigation concerned the rate of vaporization of salt water at a porous membrane surface, mass transfer of vapor through the pores of the membrane, condensation of vapor on the other surface of the membrane in contact with a coolant (fresh water), and the undesired heat transfer by conduction through the membrane. The water-repellent membrane separated the two liquid phases by surface tension forces and provided a vapor phase in its pores. Membranes made of fiberglass and Teflon had been found suitable …

The Acidic Transformaion Products Of Indoles Formed By Basidiomycetes, Chung-Ke Chang

Masters Theses

"A survey of the ability of basidiomycetes to convert tryptophan, tryptamine and indole acetic acid to other acidic indoles has been made.

The product formed from tryptamine by Tricholoma nudum was identified as indole acetic acid. The product formed by Cantharellus cibarius from D-tryptophan was identified as N-acetyl-D-tryptophan. The products were purified and identified by means of paper chromatography, thin layer chromatography, infrared spectroscopy and melting points.

The conversion of tryptamine and D-tryptophan was also studied in cultures of Leucopaxillus paradoxus, Hygrophorus conicus and Naucoria confragosa. H. conicus, L. paradoxus and N. confragosa transformed tryptamine and indole acetic acid into …

Pain Elicited Aggression As A Function Of Withdrawal From Morphine Addiction, Brian G. Teel

Masters Theses

One branch of aggression research has concentrated on the elicitation of aggressive behavior by means of exteroceptive stimulation. Electric shock or similar painful stimuli (Ulrich & Azrin, 1962) are well known to produce fighting in the laboratory rat. This basic method has allowed experimental analysis of a wide scope of associated variables.

Ulrich and Azrin (1962) investigated several different parameters. They found that laboratory rats increased their fighting behavior as the frequency of shocks increased from 0.1 to 38 shocks per minute. With frequency fixed, the fighting response rate resembled an inverted U-shaped curve when shock intensity was increased from …

Strain Differences In Alcohol Preference On Guinea Pigs And Experimental Manipulation Of Preference By Forced Alcohol Consumption, Gerald L. Appelman

Masters Theses

Introduction

The study of the determinants of alcoholism, one of the most perplexing diseases of mankind, entered its most fruitful era of discovery in the laboratory of the animal researcher. A pioneering study of the determinants of alcohol consumption by Richter (1940) indicated that laboratory rats show a preference for alcohol over water beginning at 1.8 per cent ethanol (v/v) solution, and continue to prefer alcohol over water up to a 6 per cent ethanol (v/v) solution. Richter made two important contributions to alcohol research which had broader implications than the presentation of an index of alcohol consumption in rats. …

The Effect Of Neurosecretions From The Cerebral Ganglia On Blood Glucose Levels In Lumbricus Terrestris, Joan Vanderpol Craig

Masters Theses

Introduction

The presence of neurosecretory cells in the suprapharyngeal ganglia of Lumbricus terrestris has been well established (B. and E. Scharrer, 1937). Since these cells may well be the only source of hormones in this organism (B. Scharrer, 1959), the question arises as to their role in the animal's regulation of metabolism The particular aspect of this problem investigated here concerns the effect of these neurosecretory substances on the blood glucose levels in L. terrestris.

Preliminary studies by this investigator on glucose levels in earthworms revealed that blood samples of approximately 15 microliters could be obtained from each animal and …

An Investigation Of The Surface Temperature Distribution In The Detroit Region, Allen R. Smith

Masters Theses

Chapter I

Introduction

Climate and the City

Studies made of temperature in and around cities have shown the climate of the city to be anomalous in relation to its regional climate. The extent of this anomalous condition and the reasons for its occurrence vary from city to city and from season to season. So many variable factors are present in the generation or regeneration of heat within the city that no study has yet satisfactorily explained the total factors involved, or has indicated the percentage for which any one factor might be responsible. This being the case, the only objective …

The Problem and Its Background

The Problem

The current era is called the Space Age -- a time of phenomenal scientific progress. Accordingly, improvements in science programs at all levels of education are being urged and promoted on all sides. Federal grants are offered to motivate science teachers to improve their training; federal funds are available to aid school systems in the purchase of scientific equipment; and capable high-school and college students are urged to choose careers in the sciences.

The Effects Of Estrogenic And Gonadotrophic Hormones On Normal Levels Of Some Blood Chemical Constituents In The Non-Breeding Female Mallard Duck, Wendell F. Hofman

Masters Theses

Introduction

In past years, a substantial amount of research has centered on the levels of certain blood chemical constituents in birds, particularly in chickens and pigeons. However, little has been recorded concerning the blood chemical constituents of the mallard duck, Anas platyrhynshos. Likewise, the effects of hormones on its blood chemistry, in conjunction with its reproductive system, have been almost totally unexplored. Therefore, this study, conducted from October 14, 1965, to March 3, 1966, had as its purpose the determination of normal quantitative levels of certain blood chemical constituents (the electrolytes--calcium, sodium, potassium; the proteins--albumin and globulin; and lipids) and …
