An Experimental Study Of The Effect Of Long Hair Worn By Males Upon Immediate Recall In The Classroom Situation, Edward George Sutter

Masters Theses

The appearance of the orator has been a concern of rhetoricians since the classical era. A review of contemporary literature revealed that authors in the area of communication still include theories regarding particulars of effective speaker appearance in their writings. Although authors of speech texts have become prescriptive in their directives of grooming, today’s theoretical preference for short hairstyles in educational speaking contexts has not been quantitatively tested. Therefore, this investigation was designed to experimentally assess the effects of the introduction of longer hairstyles in the classroom situation upon student’s immediate recall.

On hundred twenty-nine students enrolled in eight sections …

Preliminary Observations On The Effects Of Treflan To Fishes, P. Bradley Latvaitis

Masters Theses

Treflan E.C. is a selective, preemergence, soil incorporated herbicide. Preliminary tests were made to evaluate its effects at concentrations of 0.75, 1.275 and 1.8 p.p.m. on twenty species of fresh water fishes in the laboratory. The herbicide was proven to be a powerful fish toxicant. Centrarchus, Cichlasoma centrarchus, was the most resistant fish tested, while Bluegill, Lepomis macrochirus, was among the least resistant. Treflan E.C. decomposes and degrades rapidly. It was also found to interact with plastics. Further studies are necessary to provide a complete investigation of the effects of Treflan on Fishes.

The Life And Songs Of John Danyel, Sally J. Wylie

Masters Theses

The lute song or "ayre" as it was usually spelled by its Elizabethan and early Jacobean composers was a type of English song whose melody was predominant and its accompaniment carefully composed. It was usually accompanied by the lute and often the viol doubled the bass line. The term "ayre" or "aire" was used by English writers of the seventeenth century in the sense of key or mode. The texture of the lute song was generally homophonic and much simpler than that of the polyphonic madrigal. Of course, lutenist-song composers like John Dowland and John Danyel often used all of …

Preliminary Studies With A Variable Transfer Composite Polymer Membrane., Samuel Walter Dortch

Masters Theses

"A preliminary study was done to determine the feasibility of using a compressed fibrous teflon (PTFE) silicone polymer membrane in extracorporeal oxygenation devices. A series of composite membranes were fabricated, using different concentrations of a dimethyl silicone polymer dissolved in petroleum ether, to give membranes having variable oxygen transfer properties. A gas-gas system was chosen to obtain the necessary transfer data. Data were obtained by transferring pure oxygen through the membranes into a mixture of 47 mole percent oxygen and 53 mole percent carbon dioxide. All analyses were obtained by chromatographic techniques. The results of these experiments show that membranes …

Analysis And Measurement Of A Zener Diode Voltage-Reference, Armond C. Maxeiner

Masters Theses

"Output voltage sensitivity equations are derived for a zener voltage-reference circuit. The circuit consists of a DC-DC converter, a voltage-resistor current generator, and a zener diode. The performance of the voltage-reference is calculated using the sensitivity equations and compared to measurement data taken from a laboratory model of the circuit. The results are in reasonable agreement.

It was concluded that with careful selection of components, two of three major sources of error can be predicted and controlled; these are changes due to input voltage and changes due to temperature. The third, changes due to time, requires calibration against a voltage …

A Sensitive Temperature Measuring System, Larry Dean Morris

Masters Theses

"A sensitive temperature measuring system, providing an analog output proportional to sensor temperature, has been designed for use in the wall temperature control system of a cloud simulation chamber. A platinum resistance element is the sensor, and a precision wirewound resistor is the reference in a bridge circuit which uses four low cost operational amplifiers arranged to provide two precision 1000 Hz current sources. Problems with an initial bridge amplifier design were corrected in the final design by the use of a low Q bandpass amplifier for the bridge signal followed by a phase detector and an output low pass …

On The Complex Index Of Refraction For Liquids, Juan Guillermo Ochoa Sierra

Masters Theses

"Methods for determining the optical constants, the real and the imaginary part of the complex index of refraction, for weakly and strongly absorbing liquids are reviewed and evaluated. Both reflection and transmission methods were considered and preliminary steps are taken for determining the optical constants for both water and oil in the visible region (0.45 - 0.65 microns) of the spectrum. A low resolution spectrometer was used and the transmission measurements through fuel oil, number 1 through 6, and crude oil were performed. The imaginary part of the complex index of refraction was deduced from the above measurements and appears …

An Investigation Of Stage I Fatigue Crack Growth In Fcc, Bcc, And Hcp Metals, Marion Anthony Russo

Masters Theses

"The objectives of this investigation were to 1) determine if Stage I mode or fatigue crack growth could be extended beyond the 45 degree maximum shear plane in metals having a face-centered, body-centered and hexagonal close pack crystal structure; 2) identify the crystallographic planes or crack propagation in Stage I growth in each crystal structure; 3) characterize the fracture surface topography or Stage I growth in each crystal structure. The test material used for this investigation consisted of alpha brass (70% Cu, 30% Zn), Armco iron and commercially pure titanium which are representative of FCC, BCC, and HCP crystal structures …

Experimental Studies Of Supporting Wire Disturbances In The Near Viscous Wakes Of Slender Supersonic Bodies, Kenneth Anthony Mirly

Masters Theses

"Wires have often been used as a means of mechanically supporting a model so that its wake will be relatively free of support interference. Such support systems have many advantages over stings and are less costly than magnetic suspension systems. Investigations into the disturbances caused by these supporting wires have been carried out with the use of a two-dimensional flat plate and a wire supported slender cone. The tests were conducted in the University of Missouri-Rolla axisymmetric, supersonic wind tunnel at Mach 3.15, and at a Reynolds number of 2.14 X 10⁶ per inch. Schlieren photography, pitot and static pressure …

A Study And Design Of A Cardiac Interbeat Interval Timer System, Richard William Mooney

Masters Theses

"This thesis reports the design of a system which can measure and record the cardiac interbeat times of human subjects in a continuous beat to beat manner, using the bioelectrical signal associated with the heart as an input. The design is in response to the needs of clinical researchers.

The means of obtaining the bioelectrical signal and previous designs of electrocardiographic equipment, especially electrocardiotachometers, are reviewed. A design is proposed which consists of a preamplifier to amplify the bioelectrical signal, a 60 Hz rejection filter, and a beat detector which uses a differentiation technique to obtain a reliable single output …

A Study Of Fmfb Demodulator Operation In The Presence Of Radio Frequency Interference And Gaussian Noise, Terry D. Wormington

Masters Theses

"A digital computer model of an FMFB demodulator has been used to study the effects of radio frequency interference on the detection of a sinusoidally modulated carrier. The effectiveness of selecting the feedback factor to suppress the interference for three values of modulation index is investigated. Also, the required IF bandwidth for the minimization of the mean-square error of the loop output between a signal corrupted by interference and the same signal without interference was investigated. More work is required before the effects of Gaussian noise plus interference on loop operation can be ascertained"--Abstract, page ii.

A Study Of The Effects Of A Reading Program For Reluctant Readers, Florence Evelyn Banks

Masters Theses

The purpose of this study was to obtain some statistical evidence concerning the effects of a reading program for high school students rated as reluctant readers on their reading habits and attitudes. The initial problem which motivated the study was that assignments to read novels were resisted by this group. The students can read, but do not.

The hypothesis is that if students are given a program with books of 200 pages or less that have in the content some universalities that will satisfy the adult interests of students, attitudes about reading will change and there will be an improvement …
