Schedule-Induced Polydipsia: Effects Of Delayed Water Availability, James Thomas Rowan

Masters Theses

Five albino rats developed schedule-induced polydipsia when placed on a fixed-interval 90 second or fixed-time 90 second schedule of food reinforcement with water concurrently available on a fixed-ratio two. The imposition of 15 second and 30 second delay contingencies on water availability following pellet delivery failed to eliminate the schedule-induced polydipsia. Results are discussed in terms of two hypotheses previously proposed to account for the post-pellet nature of the schedule-induced polydipsic phenomenon.

Effect Of Glass Aggregates Upon Abrasiveness Of Asphaltic Mixtures, Dwarka Prasad Gupta

Masters Theses

"The utilization of glass as an aggregate in asphaltic concrete pavements has been suggested as a means for reusing the increasing amounts of waste glass generated each year in the United States. Recent studies have shown that asphaltic mixtures containing glass aggregates can be designed to meet Marshall requirements for stability, flow and void content but the abrasiveness of mixtures containing glass aggregates had not been investigated. The objectives of this study were to develop a laboratory wear testing apparatus and compare the abrasiveness of asphaltic concrete mixtures using glass aggregates with the abrasiveness of mixtures using several different conventional …

Design And Construction Of A Drop Generator For Use In A Vertical Wind Tunnel, Danny Ray Conner

Masters Theses

"A drop generator, based on the principle of a vibrating capillary, was designed and built for use in the UMR vertical atmosphere wind tunnel. The drop generator worked very well on a test stand where it was firmly supported, but was not consistent when tested in the wind tunnel. Vibration of the wind tunnel walls and a slight turbulence near the forward edge of the generator caused an oscillation in the position of the stream of drops. The oscillation resulted in some of the drops hitting the edge of the collector cup, where the drops would accumulate until a large …

Effect Of Biological Activity On Pesticide Desorption, Loh-Tien Chiang

Masters Theses

"The purpose of this research study was to investigate the effect of biological activities on the desorption of pesticides from humic acid solids. The pesticides selected in this study are dieldrin and heptachlor, both of which have been commonly used in agricultural applications. The humic acid adsorbent was extracted from a coal-like substance called "leonardite", which has a humus content of as high as 53 percent by weight. The first step of this study involved a proper cultivation of biological culture so that the culture could be adapted to a test environment containing a high concentration of humic acids. The …

Design And Analysis Of A Phase-Locked Loop Suitable For Synchronization Of An Optical Receiver, Douglas Wayne Dreisewerd

Masters Theses

"The required synchronization of a dynamic crossed-field photomultiplier tube (DCFP) is accomplished by means of a phase-locked loop for which the salient feature is the use of the DCFP as the phase detector. This action is necessitated due to the unique sampling and phase focusing type of operation of the DCFP. The phase-locked loop is implemented by dithering the phase of the synchronizing RF drive signal, bandpass filtering the output pulses of the DCFP and using a synchronous detector at the dither frequency to determine the phase relationship between the incoming mode-locked laser pulses and the RF drive signal. The …

The Analysis Of An Axially Symmetric Submerged Membrane Shell, Walter Earl Wehmeyer

Masters Theses

"The general theory of large elastic deformations is applied to the problem of a liquid-filled, axisymmetric membrane which is supported on a rigid horizontal plane and subjected to a variable external pressure. The variable external pressure is caused by submerging the membrane to various depths. The variation of the hydrostatic pressure in the inflating medium as well as in the surrounding environment is considered. By assuming large meridional deformations the stress field and the deformed shapes of a submerged membrane made of a neo-Hookean material are obtained. The effect of the initial shape on the deformed configuration of the membrane …

Mechanism Of Ual₃ To Ual₄ Transformation, Ling Ping Lee

Masters Theses

"The UAl₄ compound which forms during the peritectic reaction, Liquid + UAl₃ - UAl₄ , has a long needle-like shape and a characteristic morphology of fish-tail when cut along the long axis. It has an internal core of another phase when cut perpendicular to the needle axis. Because of the interesting similarity between UAl₃ and UAl₄ crystal structures, the peculiar UAl₄ morphology could be explained. The mechanism of UAl₃ to UAl₄ transformation is identified as shear and diffusion controlled transformation"--Abstract, page ii.

A Study Of Three Methods Which Solve A Suboptimum Control Problem On An Iterative Analog Computer, Joseph Camp Finney

Masters Theses

"Three methods for optimizing a proportional and a proportional-integral controller parameter problem were investigated on an iterative analog computer. The three methods were the parameter-perturbation correlation method, the absolute biasing method, and the variable step size method. The process controlled was third order linear. The performance function used to judge the quality of the controller was the time integral of the absolute value of error. All three methods required a trial and error adjustment of the parameters used in these methods. The optimum solution was obtained by all methods. The absolute biasing method, for both the proportional and the proportional-integral …

An Analysis Of Single Wire Earth Return (Swer) System For Rural Electrification, Balwinder Singh Samra

Masters Theses

"The primary objective of this investigation was to determine the general applicability of Single Phase Earth Return(SWER) system for rural electrification where the load density is low, for example electrification of farms and small villages in emerging nations. The limitations of SWER system of distribution are many and it is necessary to make judicious use of such transmission. In this investigation the construction costs of transmission and distribution by SWER system is compared with single phase and three phase systems for loads of 25KVA and 50KVA. Phase converters are required to operate a three phase motor on a single phase …

Adsorption And Desorption Of Chlorinated Hydrocarbon Pesticides By Organic Humic Sludge, Fu-Sheng Chien

Masters Theses

"This research study was undertaken to investigate the fundamental sorption and desorption of selected organic pesticides by organic humic acids under laboratory-controlled conditions. Emphasis was placed on the evaluation of both the rate and the equilibrium of adsorption and desorption. Two types of chlorinated hydrocarbon pesticides were employed in this study. These are dieldrin and heptachlor, both of which are commonly used in today's agricultural applications. The adsorbent of organic humic acids was extracted from a coal-like substance called "leonardite," which has a humus content as high as 53 percent by weight. The experimental work of this study was conducted …

Investigation Of A New Type Of Cloud Condensation Nuclei Counter: The Thermal Quench Chamber, Donald Arthur Hess

Masters Theses

"The design and development of a new type of cloud condensation nuclei counter was undertaken to provide a new laboratory and field instrument that operates on a different theoretical basis than the thermal diffusion chamber now being used by meteorologists and other scientists. In the new instrument the test aerosol is pumped through a tube where it is first humidified and then cooled at constant pressure to create a supersaturation, causing water vapor to condense upon the nuclei in the aerosol sample. The concentration of cloud condensation nuclei is then determined by counting the water drops. The control of temperature …

Fitting Discrete Probabilistic Frequency Distributions To Disturbed Traffic Flow At An Unsignalized Urban Intersection, Horst Walter Kaminsky

Masters Theses

"Traffic variables, such as volume, speed, gaps and lags, and headways can be described by probability distributions. In this study vehicle arrivals from three directions have been recorded at a four-leg, right-angled, at-grade intersection in Rolla, Missouri, and statistically analyzed. Two distinct probabilistic statistical concepts were used, the continuous (gap) and discrete (counting) distribution. The negative exponential distribution is discussed briefly, whereas the applicability of discrete statistical models for the traffic situation selected is elaborated in detail.

The purpose of this research was to investigate the impairment and distortion that various interferences such as upstream traffic lights, bottlenecks or other …

The Social History Questionnaire As Related To Length Of Stay In Psychotherapy, David P. Jachim

Masters Theses

A serious problem encountered in clinical practice concerns the large proportion of clients who begin therapy but for various reasons terminate treatment after only a few interviews and without the consent of the therapist. Representative studies by Kurland (1956), Haddock and Mensch (1957), and Rosenthal and Frank (1958) have emphasized the severity of this problem by indicating that most mental health clinics face the possibility of losing half of their therapy clients prematurely.

This problem necessitates some objective means for identifying potential terminators and remainers prior to their entering therapy. Such a technique would permit a more efficient utilization of …

A Study Of Thoracic Skeletomusculature In Peracarida (Crustacea), Donna R. Gill

Masters Theses

Two species of peracarid malacostracans, a mysid, Neomysis americana, and an oniscid isopod, Trachelipus cf. rathkei, were used to study the skeletomusculature system. Serial sections, whole mounts, and gross dissections were made. Coxal promotors and remotors and basal adductors and abductors were the muscle groups examined.

The promotor and remotor muscles of N. americana were found to be numerous, well developed, taking origin primarily from the dorsal thoracic wall, and extending nearly ventrally to insert in the coxa; the adductor muscle and two abductor muscles are weakly developed. The coxa in T. cf. rathkei is incorporated completely …
