Remote Sensing Of Environmental Parameters, Wendell Princeton Perkins

Retrospective Theses and Dissertations

Atmospheric pollution in some degree has been around since time began. In recent times it has reached levels in some areas which proved to be harmful to man's health. A brief history review of these occurrences is presented. Laws have been enacted to combat this threat. A brief review of these laws is presented. Instruments for remote sensing of polluting sources are being developed to monitor ambient air quality and aid in enforcing these laws. A review of the techniques employed and the present state of the art is explored. Available instruments are presented in section III-5.

Localized Wastewater Treatment Facilities, Robert Russell Garrett

Retrospective Theses and Dissertations

The report describes an alternative to the use of septic tanks for invidual dwellings. The major problems confronting the larger wastewater treatment plants (0.012 to 10 million gallons per day) in central Florida are also discussed. Solutions in this report are for individual and multi-unit dwelling treatment systems (to 0.06 MGD). these units can provide 90% biochemical oxygen demand (BOD) and suspended solids (SS) removal in accord with new state and county regulations. A comparison of the large versus the small plants reveals that small innovative plants, though more expensive, are more environmentally sound than the poorly operated large facilities. …

Sinkholes In Florida And Their Effect On Man's Environment, Gregory Jackson Skinner

Retrospective Theses and Dissertations

The primary reason for making the research study on "Sinkholes in Florida and Their Effect on Man's Environment", is an interest in learning more about this somewhat unique phenomenon and how it is likely to affect man in the future, particularly here in Central Florida. This is significant at this time in view of the large number of existing sinkholes, the frequency of occurrence, the projected population and economic growth, and the possible impact this growth may have on future sinkhole occurrences. The research concentrated on possible causes, effects, frequencies, locations and mean of predicting future sinkhole development. There is …

A Mathematical Model For Determining The Thermal Distribution Resulting From Discharge Of A Heated Effluent, Alan H. Epstein

Retrospective Theses and Dissertations

A mathematical model is presented for the problem of determining the two-dimensional temperature distribution resulting from the discharge of a heated effluent into a shallow, quiescent receptacle. The physical model of the problem is the two-dimensional jet augmented by an imposed condition of viscous drag due to bottom friction effects. By virtue of the assumption that the physical properties of the effluent are independent of temperature over the operational temperature range of the plume, the analysis separates the total problem into a flow problem and a temperature problem. Solution of the temperature distribution is accomplished both analytically and numerically. Analytically, …

Suppression Of Turbofan And Turbojet Engine Generated Noise, Harry David Master

Retrospective Theses and Dissertations

Every advance in the transformation of heat energy into mechanical energy has involved a noise problem, and in general it increases with the power production. The jet airplane is a good example: the large-scale turbulence of the exhaust gases in the jet forms an unusually intense source of sound the control of which is quite difficult. The additionally generated fan noises add characteristic fan tones which are particularly noticeable on landing approaches. the human ear is the vulnerable receiver of these noises, and the problem becomes one of deciding how much jet engine noise reduction is required for the comfort …

A Review Of "Longitudinal Study" In Developmental Psychology, Emily H. Finley

Dissertations and Theses

The purpose of this library research thesis is to review the "longitudinal study" in terms of problems and present use. A preliminary search of the literature on longitudinal method revealed problems centering around two areas: (1) definition of "longitudinal study" and (2) practical problems of method itself. The purpose of this thesis then is to explore through a search of books and journals the following questions:

1. How can “longitudinal study” be defined?

2. What problems are inherent in the study of the same individuals over time and how can these problems be solved?

A third question which emerges from …

On The Mechanism Of The Diels-Alder Reaction--Dimerization Of Trans-Phenylbutadiene, Michael Ward Mcnicholas

Dissertations and Theses

The Diels-Alder dimerization of trans-1-substituted butadienes is expected to yield a cyclohexene adduct with the substituents in the 3 and 4 positions cis to one another. This prediction is based on past observations of other Diels-Alder additions. The cis-isomer is the only one consistent with a two-stage mechanism proposed by Woodward and Katz.

In the case of trans-phenylbutadiene, the expected adduct is cis-3-phenyl 1-4-(trans-styry1) cyclohexene. Alder, Haydn and Vogt, however, reported that the corresponding trans-isomer is the dimerization product. There is reason to believe that the observation of the trans-isomer may have been the result of product isomerization during purification. …

Reaction Of Aqueous Catechol Solutions With Minerals, Boonthong Poocharoen

Dissertations and Theses

The effectiveness of catechol, an aromatic vic-diol, in dissolving silicate minerals was studied. A synthetic amorphous magnesium trisilicate, Mg₂Si₃O₈∙5H₂O, as well as the minerals olivine, sepiolite, diopside, augite, and enstatite were used to react with catechol in slightly acidic, basic, and neutral solutions. It was found, depending on the solvent used, that 33-52, 8-17, 14-30, 5-11, 3-6, and 0.5-1 % of the minerals dissolved, respectively.

The reaction with Mg₂Si₃0₈·5H₂0 resulted in the formation of crystals of magnesium tris (catecholato) siliconate nonahydrate Mg[Si(Cat)₃]∙9H₂0. Dehydration of the crystals at room temperature resulted in the loss of 6 moles of water to form …

Computer Method For Airport Noise Exposure Forecast, John Michael Bateman

Retrospective Theses and Dissertations

The major problem facing air transportation for the next decade is aircraft noise. The noise level due to the operation of large jet aircraft has created a very serious annoyance problem to the people living near of adjacent to jet airports. The noise problem has developed both for take-off and landing operations of these aircraft with take -off noise causing the greatest annoyance factor. A technique called Noise Exposure Forecast (NEF) has been developed to identify the annoyance factor of these noises to people and activities on the ground. With these NEF ratings or numbers, planners can better determine the …

Geology Of Southern Nelson County, North Dakota, Roger J. Reede

Theses and Dissertations

Southern Nelson County occupies 576 square miles in northeastern North Dakota (Twps. 149-152 N., Rgs. 57-62 W.). Its surface is mantled with glacial drift resting unconformably on the Cretaceous Pierre Shale, which is exposed along the Sheyenne River Valley and the Stump Lake Basin. The entire mantle of glacial drift is part of the Coleharbor Formation, which, in southern Nelson County, averages 45 feet thick with a maximum thickness over 200 feet. Drill-hole data and missile site excavations provide good evidence for the existence of multiple drift sheets, including layers of till separated by more than 25 feet of outwash, …

An Investigation Of Methods For Reuse Of Rubber Tires, Charles Edward Armbruster

Retrospective Theses and Dissertations

Methods of reusing/recycling the more than 250 million automobile and truck tires which are worn out each year were investigated. The existing methods of reusing tires account for about 30 percent of the volume of scrap tires generated each year. These methods are, Retreading, Reclaiming (by reducing to ground up rubber and fiber), and Tire Splitting (stamp items out of sidewall and tread areas). Several possibilities for reusing/recycling the unused 70 percent were discovered. These methods are as follows: Destructive Distillation -- a method of recovering chemicals from tires by pyrolitic action. It is anticipated that eventually as much as …

Chemistry Faculty Research & Creative Works

The crystal structure at room temperature and the low-temperature heat capacity and magnetic susceptibilities of single crystals of [(CH3)3 NH]CuCl3 2H2O are reported. The monoclinic crystals belong to the space group P21c with a=7.479(10), b=7.864(11), c=16.730(23), =91.98(3)°, and Z=4. The structure consists of chains of edge-sharing [CuCl4(OH2)2] octahedra running along the a axis. Each copper atom is coordinated in a square plane by two water molecules and two chlorine atoms, with two more chlorine atoms at a longer distance. The susceptibility data can be fitted adequately between 1.5 and 20°K by a CurieWeiss law [ga=2.080.01, gb=2.020.01; gc=2.110.01; a=(0.380.03)°K, b=(0.360.03)°K, c=(0.410.03)°K], …

Nonrandom Characteristics Of Common Stock Prices, Donald Leroy Gaitros

Doctoral Dissertations

"This study presents an application of operations research techniques to the development of stock price generation and simulation models to aid in the understanding of price movement. Relationships between stock price and volume and stock price and market averages which follow descernible trends and patterns are discovered. Technical trading rules are developed based on these relationships which empirically have shed doubt on the random walk hypothesis of price movement. This in turn gives evidences that technical analysis can be an aid to price forecasting"--Abstract, page ii.

Quasi-Pseudometrics Over Tikhonov Semifields And Fixed Point Theorems, Ronald Evans Satterwhite

Doctoral Dissertations

"It has been shown that topological spaces are characterized as quasi-pseudometric spaces over some Tikhonov semifield.

Sufficient conditions are given for a T₁ space to be metrizable over some Tikhonov semifield.

Completely regular (uniform) spaces are characterized as pseudornetric spaces over some Tikhonov semifield.

Certain metric, pseudornetric, quasi-metric, quasipseudometric spaces over a Tikhonov semifield are shown to be respectively metric, pseudometric, quasi-metric, quasipseudometric spaces in the usual sense.

Several results from fixed point theory in the metric space setting are generalized to the setting of completely regular (uniform) Hausdorff spaces."--Abstract, page ii.

Statistical Studies Of Various Time-To-Fail Distributions, James Addison Eastman

Doctoral Dissertations

"Three models are considered that have U-shaped hazard functions, and a fourth model is considered that has a linear hazard function. Several methods for estimating the parameters are given for each of these models. Also, various tests of hypotheses are considered in the case of the model with the linear hazard function. One of the models with a U-shaped hazard function has a location and a scale parameter, and it is proved in general that any other parameters in a distribution of this type are distributed independently of the location and scale parameters.

A new method used to estimate the …
