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 …

The Geology And Hydrogeology Of The New Lead Belt, Missouri, Charles Scott Fletcher

Masters Theses

"In order to analyze the effects of pumping groundwater from underground lead mines upon present groundwater resources of the New Lead Belt area, the geology and hydrogeology of that area must first be determined. The primary method of investigation of this analysis was interpretation of ecologic and hydrogeologic data taken from water well logs and mineral exploration well logs, with supplemental information supplied by published and unpublished literature sources. From all these sources of data, structural contour maps of the Precambrian erosional surface; the tops of the Lamotte, Bonneterre, and Davis Formations; isopachous maps of the Davis and the Lamotte/Bonneterre …

2.5 Ampere Dc Solid State Power Controller, John Anthony Gilbert

Masters Theses

"The 2.5 Ampere DC Power Controller presented in this paper is a device which combines the properties of both relays and circuit breakers solely by means of solid state circuitry to perform the power functions that (1) provide DC power to electrical loads by means of power transistor switching, and (2) provide electrical protection by generating trip out characteristics similar to those of thermal circuit breakers. Furthermore, the control of this device is completely computer compatible, i.e., it is commandable from digital logic levels.

The text of this report discusses the requirements, specifications, and design of this power controller. In …

A Computerized Simulation Of A Personal Rapid Transit System., James Richard Cromer

Masters Theses

"The movement of people from an origin to a destination has become a complex and sometimes severe problem, The present modes of transportation available, which include the rapid rail systems, bus transit service, and the personal automobile, have proven quite ineffective in dealing with the situation, A new concept in the transportation area is that of Personal Rapid Transit (PRT). This concept offers a promising solution to many of our people and goods movement difficulties. Before this new system can be implemented it is necessary that various design, construction, and operational criteria be evaluated to determine the optimal system to …

Interpretation Of Imagery Lineations, Logan Creek Area, Southeast Missouri, Gregory Paul Smith

Masters Theses

"Depletion of ore in Missouri's old lead districts and the opening of the state's new lead district adds impetus to understanding and delineating geologic structure in and adjacent to the new lead district. Image and geomorphic analysis, hydrologic data, and subsurface structural contour mapping are used in interpretation of geologic structure in Dent, Shannon, Reynolds, and Carter counties, Missouri. Unlike the time consuming surface geologic mapping, the modes of investigation used in this study enabled the writer to make a larger, regional-scale study with results comparable to those attainable by surface mapping. The area is covered by thick residual soils …

Experimental Determination Of Improved Aerodynamic Characteristics Utilizing Biplane Wing Configurations, Elmer Carl Olson

Masters Theses

"Improving the aerodynamic characteristics of an airplane with respect to a higher lift coefficient, a lower drag coefficient and a higher lift over drag ratio as a function of angle of attack will make it more efficient, thus conserving energy or improving performance. Investigations were carried out to determine if the aerodynamic characteristics of biplane wing systems could be made more efficient, for low subsonic speeds, than a monoplane of comparable area and aspect ratio. A variable position three-dimensional biplane wing system, and a fuselage that could be fitted with a monoplane wing or the variable position biplane wing system …

Relative Performance Of Two Activated Carbons In Treating Pharmaceutical Waste., K. A. Narasimhan

Masters Theses

"This work examined the feasibility of the carbon adsorption system to treat a high organic strength waste (having a COD of 8,100 mg/£) from a pharmaceutical plant, and also compared the relative treatment efficiencies of two different kinds of carbon~ Calgon Filtrasorb 400 and Darco S-51, both having the same size ranges.

The overall treatment scheme employed consisted of chemical clarification and activated carbon adsorption. Jar tests were conducted to select a proper type of coagulant and determine an optimum dosage. Batch and column adsorption studies were conducted using both carbons.

Alum was found to be a better coagulant than …

Mercury Distribution In A Massive Sulfide Ore Deposit At Balmat, New York, David Ray Jessey

Masters Theses

"Ore samples consisting of diamond drill core and mine samples, collected from several Balmat ore bodies, were analyzed for their mercury content. The average contents in these ore bodies were found, in ppb, to be: Upper Gleason, 829; Middle and Lower Gleason, 504; Loomis, 546; Fowler, 195; No. 1 Zone, 37; Sylvia Lake, 59; No. 2 Mine, 5. If all of the mercury in these pyrite-sphalerite-galena ores occurs in the sphalerite, then the average sphalerite mercury contents, in ppb, are the following: Upper Gleason, 2490; Middle and Lower Gleason, 2516; Loomis, 2701; Fowler, 1376; No.1 Zone, 384; Sylvia Lake, 408; …

A Planning Study On The Electrical Load Requirement For The New Town Of Pattonsburg, Javad Yousefian

Masters Theses

"Because of an Army Corps of Engineer proposed new dam on the Grand River 1 the original town of Pattonsburg, Missouri was to be inundated by the resulting lake reservoir formed above the dam. The city planners proposed the relocation of the town site adjacent to the new lake, forming a lake side community attractive to both a residential population and for industrial locations.

The electrical power loads of New Pattonsburg's residential, industrial, commercial, and municipal areas, as well as its street lighting power requirements, were planned for a population of 50,000. Statistical analysis of demographic surveys was employed to …

Magnetostrictive Aftereffects In A Dilute 50fe-50ni-C Alloy, Raj N. Master

Masters Theses

"Crystallographically equivalent interstitial sites are energetically equivalent when the host crystal is free of any fields. This situation is shown in Fig. Pl from which it may be appreciated that the difference of the free energy of the "crystal" with an interstitial "I" located in "x" and "y" sites, respectively, is equal to zero. This energy equivalence of the various interstitial sites is destroyed when the host crystal is subjected to fields such as strain fields, magnetization fields or a combination of both as may be appreciated from Figs. P2 through P4. In this case, the interstitials will preferentially occupy …

Determination Of Oxygen Chemical Diffusion Coefficients In Single Crystal Strontium Titanate By Capacitance Manometry, Douglas Bugh Schwarz

Masters Theses

"The use of the tensi-volumetric apparatus to study the non-stoichiometric behavior of strontium titanate was discussed. Oxidation kinetics of reduced single crystal strontium titanate were measured with an ultrasensitive capacitance manometer as the sample absorbed oxygen in response to a changing oxygen activity.

The oxidation kinetics were found to fit a solution to Fick's second law for rectangularly shaped samples....

The procedure selected for measurement of the oxidation kinetics, and the method of obtaining diffusion coefficients from the oxidation data was discussed along with potential sources of error of the system"--Abstract, page ii.

An Economical-Digital Interface For Multiplex Recording Of Analog Signals, Samuel Knoles George

Masters Theses

"In measuring and evaluating performance of an automobile and driver combination it is necessary to record data from the vehicle and driver while both are in the field.

The University of Missouri - Rolla Transportation Research Program performs this type of evaluation. The present method of recording data in the field is with a large, bulky, and somewhat fragile strip chart recorder.

The digital recording interface described in this paper is designed to permit replacement of the strip chart recorder with an audio tape recorder. The interface will allow simultaneous recording of two analog channels which may be reproduced as …
