Rate Of Growth As A Method Of Assessing Water Quality, George L. Johnston

Masters Theses

A study of the Embarras River basin was conducted to determine if rate of growth could be used as an indicator of water quality. Six species of sucker were collected from five locations using hand seines and electrofishing gear from December 1970 to December 1971. Tests of eighteen water quality parameters were conducted from November 1970 to November 1971.

The fish were measured and scale samples taken. The rate of growth of the fish taken at the five stations was analyzed and compared using the single classification analysis of variance. Condition factors were also compared.

Although there was some difference …

Effect Of Sweeping Sinusoidal Excitation On Nonlinear Dynamic Systems., Md. Mosharraf Hossain

Masters Theses

"The response of viscous damped, cubic spring systems to excitations having exponentially varying frequency cannot be written in a closed form. This report summarizes a numerical investigation of hardening and softening cubic systems influenced by these excitations and provides information concerning the effects of varying viscous damping, system nonlinearity, and excitation sweep rate on system behavior near resonance. Results are reported in terms of maximum response attained during sweeping and the frequency at which maximum response occurs.

It has been found that if hardening cubic systems are subjected to sweeping excitations wherein the frequency sweeps down through resonance, the maximum …

Design And Operation Of A System For The Measurement And Display Of A Railroad Train Length., Paul Clement Kriegshauser

Masters Theses

"This thesis describes the design, operation, and application of a system for the automatic measurement of a railroad train length. The system is based on sensing individual wheel crossings with two commercial variable-reluctance wheel sensors. The individual wheels are not counted as they are sensed, instead the system uses the information to compute the train velocity. These sensors are separated a known distance on the railroad track at the location a length measurement is desired. The train may pass these sensors at any desired speed and in either direction. The developed system is not dependent on car length or number …

Flow Field And Heat Transfer For Developing Flow Of Molten Glass In A Duct, Russell Ralph Beckmeyer

Masters Theses

"The molten glass flow (temperature range 1300 to 1500°C) in the entrance region of a duct was investigated with numerical methods. The mathematical model was restricted by assuming: (1) two dimensional, steady state, (2) Newtonian fluid, variable viscosity, and (3) Rosseland approximation. In addition, appropriate use was made of the fact that the Reynolds number is small and the Eckert number is very small. The inclusion of temperature dependent viscosity and a Rosseland approximation for radiation produced from the mass, momentum, and energy equations a system of coupled, nonlinear, partial differential equations which were solved by an iterative finite difference …

Metal Promoted Reactions Of Enamino Ketones, Suhas Satchidanand Joshi

Masters Theses

The reaction of 4-amino-3-allyl-3-penten-2-one (7) with mercuric acetate in acetic acid was found to produce 4-amino-1-pentene (12) in 70% yield. The scope of this unusual cleavage reaction was investigated by systematic variation of substituents on the enamino ketone framework, the metal salt and the solvent. The presence of the allyl group was necessary for the reaction to produce compound 12.

Under a variety of conditions there was no evidence for cyclization of 7 to give heterocyclic compounds. Neither was there evidence for cyclization in reactions of 4-amino-3-penten-2-one with vinyl acetate in the presence of mercury (II) or thallium (III) salts …

Pesticide Effects In A Simulated Soil Ecosystem, Raymond J. Samp

Masters Theses

The screening of pesticides to determine which were most inhibitory to bacteria was accomplished by testing the effects of 10 pesticides on 9 different organisms using the disk assay method. Results showed that Gram positive bacteria were more sensitive to all pesticides tested than were the Gram negative bacteria. In addition, the hormone herbicides were found to be the most inhibitory to these bacteria and 2,4-D (2,4-dichlorophenoxyacetic acid), a hormone herbicide, was chosen for subsequent in vivo studies.

A soil perfusion apparatus was used to determine the effects of 2,4-D in a typical soil ecosystem. Bacterial plate counts and nutrient …

The Water Quality And Benthic Macroinvertebrate Fauna Of Lake Charleston, Coles County, Illinois, Paul Barding

Masters Theses

The benthic macroinvertebrate fauna and 15 water quality parameters for five sites on Lake Charleston, Coles County, Illinois were examined for 26 weeks from March 14 through September 5, 1974. None of the water quality parameters studied showed sufficient deviations at any particular area on the lake to merit demarcated water quality zonation. The lake, with its continuous mixing and shallow depth, represented a fairly stable and continuous environment. The benthic macroinvertebrate fauna was determined as fairly diverse and some indication of seasonal variation was apparent. No significant compositional variation over different areas of the lake was found, also indicating …

Mechanism Of Solvolysis Of 3-Methyl-2-Butyl Brosylates., Luu Le Nghi

Masters Theses

"The brosylates of 3-methyl-2-butanol and it's a-d₁-, ß-d₁-, B-d₃-, and S-d₄- analogs have been synthesized. The solvolytic rate data for these compounds were determined. The solvolytic products in 70% (vol.) ethanol-water have been identified by flame ionization gas chromatography using a Carbowax 20M column. The amount of each product was measured by integrating the peak areas from the chromatograms. By analyzing the isotope effect data, the rate determining step is shown to be the formation of the hydrogen bridged ion pair intermediate. By evaluating the GC-mass spectral analysis of the isopentenes, a …

A Study Of Pollution Abatement From The F-15 Jet Engine Test Stand, Gary Joseph Fennewald

Masters Theses

"The pollutants emitted from jet engine test stands are carbon particles, unburned hydrocarbons, carbon monoxide, and the oxides of nitrogen. This work is a study of various ways of removing these pollutants from the test stand exhaust. The methods investigated include absorption, adsorption, electrostatic precipitation, filtration, catalytic reduction and oxidation, and thermal oxidation.

For abatement of nitrogen oxides, none of the present methods is considered to provide adequate technical reliability to proceed with an installation at this time. Each of the methods for removal of nitrogen oxides has high capital and operating cost; and, in many cases, secondary pollution problems …

Two-Dimensional Radiant Interchange In A Non-Isothermal Cavity Formed By Two Semi-Infinite Parallel Plates., Robert David Allen

Masters Theses

"Two-dimensional radiant interchange between non-isothermal, gray diffuse surfaces with non-uniform radiosity have been investigated for a cavity formed by two semi-infinite parallel plates. The problem is solved for two specific emissive power distribution models. Both emissive power distributions decay exponentially with depth into the cavity. The first emissive power distribution varies in a cosine manner across the front of the plates and the second has a step variation across the front of the plates.

For the cosine varying model, separation of variables and Ambarzumian's method are applied to obtain an integro-differential equation for the radiosity inside the cavity, an integral …

Application Of An Inverse Heat Conduction Technique To A Simulated Injection Mold., Noel Joy Rytter

Masters Theses

"An analytical model was constructed to investigate the heat transfer in an injection mold for which the temperature was controlled by a special mold heating-cooling process. Several techniques were used to test the validity and accuracy of the analytical model of the mold and to explain some singularities that occurred. It was determined that the thickness of the plastic part being molded is the primary factor affecting the minimum cycle time for the molding operation. Also, abrupt changes in temperature on the molding surfaces are very difficult to obtain because this requires drastic temperature changes for the working fluid that …

Laboratory Evaluation Of Dynamic Soil Properties By Ultrasonic Testing Methods, Ronald Maurice Eckelkamp

Masters Theses

"Measurement of ultrasonic compression and shear wave velocities through a soil material has been made with a pulse wave generator developed at the University of Missouri-Rolla. The variation of these velocities along with the behavior of the dynamic material parameters of the material (Young's modulus, shear modulus, Poisson's ratio) with void ratio and degree of saturation were determined. Compression wave velocity, shear wave velocity, Young's modulus and shear modulus were found to decrease with increasing void ratio; degree of saturation was of little influence. Wave attenuation could not be measured by the test procedure used"--Abstract, page ii.

A Computational Method For Determining The Growth Rates Of Saline Water Drops., Robert Alexander Fletcher

Masters Theses

"A phenomenologica1 theory is presented which describes the growth or evaporation of cloud droplets containing dissolved NaCl. The main interest is in the early stages of growth. The Maxwell-Fuchs equation is employed with refinements to account for the high sa1t concentration in small droplets. A computer program is presented that ca1culates the growth time as a function of radius for cloud droplets nucleated with NaCl.

The growth times obtainable from the Maxwe11-Fuchs equation differ significantly from the growth times ca1culated using the refined Maxwell-Fuche equation for ambient relative humidities less than or equal to 100%. Growth times for droplets nucleated …

Combined Forced And Free Convection On A Vertical Cylinder And Flat Plate, Aleksandros Mucoglu

Masters Theses

"In the study of fluid flow over heated surfaces, it is customary to neglect the effects of buoyancy force when the flow is horizontal. However, such a practice is not justified when the forced flow is along an inclined or a vertical surface, because under these conditions the buoyancy force modifies considerably the flow field and hence the heat transfer rate from the surface. Such a flow is termed combined forced and free convective flow.

The present study is concerned with the effects of buoyancy force on forced convection along an isothermal vertical cylinder and a flat plate. This type …
