The Osteology And Myology Of The Head And Neck Region Of Callisaurus, Cophosaurus, Holbrookia, And Uma, The "Sand Lizards", Douglas Charles Cox

Theses and Dissertations

Blainville (1835) wrote the first description of a sand lizard and named it Callisaurus draconoides. Since his time various authors have published articles concerning sand lizards. Girard (1851) described Holbrookia maculata, Trochel (1852) described Cophosaurus texanus, and that same year Baird and Girard synonymized Cophosaurus with Holbrookia providing the name Holbrookia texana, which has stood for over 100 years. Subsequently, Baird (1858) described Uma notata.

Sensitivity Of Process Variables On Rigid Polyurethane Foaming, Bruce A. Pugsley

Theses and Dissertations

Inadequate understanding and/or control of the polyurethane rigid foam process normally requires five to ten percent overpack of cavities to obtain correct fill and foam characteristics. This practice of overpacking has resulted in excessive waste and cost.

Potential Diets For Carp Production, Rex Carlton Infanger

Theses and Dissertations

The objective of this study was to determine the feasibility of raising carp on pig manure and coli, Brassica campestris. The use of pig feces as a source of fish food has been questioned by researchers (Hickling 1968). Coli was selected for dietary intake by fish since it is used for human consumption by the Indians of Guatemala. Commercial fish food (Silver Cup) was used for a control diet. These diets were both combined and used as a single source of food.

The Glacial Geology Of Mckenzie County, North Dakota, Clark Fulton

Theses and Dissertations

Fourteen lithostratigraphic units composed of windblown, glacial, lake, slopewash, and stream sediment were distinguished in McKenzie County, The units were mapped using aerial photographs, topographic maps, and soil maps combi11ed with field e:xaminations of sediment outcrops. Eight of the units have been formally named and described in earlier studies. Four of them, however, have not been a"~ previously named and formally described .a.nu assigned names in this study. Two other units are described, but because of their limited exposure, are not assigned a formal lithostratlgraphic name. The oldest sediment exposed in the county was deposited during the Paleocene and the …

Processing Pictorial Information: Effects Of Informativeness, Location, And Duration, Richard L. Metzger

Theses and Dissertations

When an observer views a picture, enough information processing occurs prior to the first eye movement to direct the eyes to an informative portion of the picture. This early processing is influenced by the overall coherency of the picture and the informativeness of the various sections of the picture. The present study tested the hypothesis that the processing of pictorial information proceeds in a hierarchical manner from the most informative sections of a picture to the least informative sections. The hypothesis was evaluated by observing changes in the recognition accuracy of high medium and low informative sections of a picture, …

On The Dutch Expletive And Related Syntactic Problems, Kornelis J. Boot

Theses and Dissertations

In his Über das niederländische Adverbialpronomen 'er' Bech argues that the subject expletive of Dutch is inserted when the NP subject has an indefinite article. Bech also claims that the subjective expletive is a local subject and not a logical subject.

This thesis proposes that the use of the subject expletive cannot be based upon a traditional structuralist concept. The author rejects some of Bech's claims and argues for a semantic distinction between definiteness and non-definiteness as a basis for expletive insertion. An attempt is also made to apply the same distinction in accounting for the use of het with …

Spatial And Temporal Partitioning Between Sympatric Rodents: Zapus And Peromyscus, Emma Bernice Speer

Theses and Dissertations

Partitioning space and time by seemingly sympatric rodents, Zapus princeps and Peromyscus maniculatus, were examined as possible mechanisms allowing coexistence. The two populations were studied in Central Utah with an electrically monitored grid. Spatial separation of individuals and the populations minimized confrontations and created local allopatric distribtuions. Temporal partitioning was not used as a mechanism to allow coexistence and was apparently independent of spatial partitioning. The Peromyscus population was composed primarily of males which may have been due to less favorable habitat and/or presence of Zapus. The data show that Peromyscus tend to avoid Zapus, possibly due to deleterious aggressive …

Voltammetric And Electrochemical Kinetic Studies Of The Halides And Halogens At A Platinum Rotating Ring-Disk Electrode In Anhydrous Acetic Acid, Donald Harrison Cranney

Theses and Dissertations

The electrochemical behavior of the iodine-iodide couple was investigated in both basic and neutral acetic acid solutions at a platinum rotating ring-disk electrode. Voltammetric curves were obtained and discussed. Various kinetic parameters were determined and by comparing to theoretical kinetic parameters a probable reaction mechanism was deduced. The mechanism that best fit experimental results is the following I- + S = I(S) + e- I(S) + I- = I2 + S + e (slow). The electrochemical behavior of bromine, bromide, and chloride was also investigated in the same media. Voltammetric curves were recorded and discussed with emphasis on the hysteresis …

A Study Of Selected Photo Fries Rearrangements, Elwood Lloyd Loveridge

Theses and Dissertations

The Fries rearrangement of phenyl esters is reviewed and compared to the reaction when light is the source of energy. The products are different due to different mechanism of reaction. Light energy causes either free radical or concerted reactions. The S-phenylthiol esters and anilides were studied also. Although many of the rearrangements are the same, we did not see any alkyl migration nor decarboxylation type reactions with either the sulfur or nitrogen compounds. Three papers have been published from this work: Bradshaw, J. S., Knudsen, R. D. and Loveridge, E. L., J. Org. Chem., 35, 1219 (1970); Bradshaw, J. S., …

The Snowy Egret (Egretta Thula Brewsteri) A Life History Study At Utah Lake With Comments On The Subspecies Status, Gerald Leigh Gunnell

Theses and Dissertations

This study was conducted to augment the limited information available regarding the Snowy Egret in the Utah Lake area of Utah. Field observations included the following: nesting habits; egg and clutch sizes; sexual, defense, and feeding behaviors. Analysis was made of the distinguishing subspecies characteristics (culmen, tarsus, and wing length) of the Snowy Egrets and of the distribution of the birds. Field observations showed that growth measurements of the young varied from 16.75 g at hatching to 260.58 g after 17 days. Culmen and tarsus measurements were 15.41 mm and 14.12 mm to 53.18 mm and 62.18 mm, respectively, after …

Defense Mechanism And Feeding Behavior Of Pteraster Tesselatus Ives (Echinodermata, Asteroidea), James Milton Nance

Theses and Dissertations

Pteraster tesselatus is noted for its external secretion of massive amounts of mucus. The mucus repels most animals, and fouls their respiratory physiology, if contact is maintained for any length of time. It provides protection essentially 100% of the time from Solaster dawsoni and Pycnopodia helianthoides, the only local stars that attempt to feed on Pteraster. The mucus, which is a simple mucopolysaccride, is produced in three different types of unicellular glands located in the epidermal tissues along the supradorsal membrane. Pores along the lateral walls of the ambulacral grooves provide fresh sea water for the dermal branchiae contained in …

Affective Influences On Nonverbal Immediacy, Steven F. Dreyer

Theses and Dissertations

This dissertation focused on compensatory relationships among the nonverbal "immediacy" behaviors—interpersonal distance, gaze, trunk lean, and body orientation--which are hypothesized to be important in the communication of interpersonal attitudes (Mehrabian, 1972; Patterson, 1973). Argyle and Dean (1965) have proposed that in social situations there are both approach and avoidance forces (e.g., affilia- tive needs, fear of intimacy) which eventually balance at some level of mutual comfort for the interactants. Once a comfortable intimacy-equilibrium has been established, any change in immediacy by one interactant requires a compensatory adjustment by the other. Since distance, gaze, trunk lean, and body orientation are assumed …

Effect Of Hemorrhage On Blood Flow To Marrow And Osseous Tissue In Conscious Rabbits, Glenn T. Syftestad

Theses and Dissertations

The purpose of this experiment was to characterize cardiovascular responses in skeletal tissue 15 minutes and 16 hours following reversible hemorrhagic hypotension and to validate a quantitative method for measuring blood flow rates in marrow and bone.

Cardiac output and regional blood flow determinations were made using the radioactive microsphere technique. Microspheres (15 u dia) were injected into unanesthetized rabbits via a chronically implanted left atrial catheter. Blood flow and cardiac output measurements were made by injecting individual microsphere isotopes, each with a different label (®^Sr, 5 1 c r Gr l ^ C e ) , at three specified …

Verbal And Imaginal Mediation In Cognitive-Behavior Modification, Steven L. Shearer

Theses and Dissertations

There has been a recent proliferation of outcorie research on cognitive-behavioral treatment packages; however, little attention has been directed toward investigating the active ingredients of such conglomerate packages. The present study was designed to investigate the relative contributions of verbal and imaginal cognitive mediators in reducing publicspeaking anxiety with other treatment factors held constant.

Therapists' manuals were constructed for the two tynes of intervention so that they were identical except for the focus on either verbal or imaginal mediation. The treatments drev/ from techniques suggested by Meichenbaum (1974a), Goldfried (1971), and Suinn (1975a; 1975b), but the parallel format of the …

Syntactic Combinations Of Verbs In Lakota Sioux (Teton Dakota), Michael Robert Scott

Theses and Dissertations

The purpose of this thesis is to explain the differences among syntactic combinations of verbs in Lakota Sioux (Teton Dakota). The thesis at first examines the literature on combinations of verbs in Lakota. Thereafter criteria for distinguishing morphological combinations of verbs (compounds) and syntactic combinations of verbs are set forth. The criteria are: potential for replacement, regularity of meaning, and potential for variation in inflection. The emphasis of the thesis is on the classification of syntactic combinations of verbs which it proposes.

The classification contains six classes, two of which are subdivided. The classification is based on the interaction of …

A Comparison Of The Effects Of Timeout, Punishment And Extinction On An Aggressive Behavior In Children, Diane M. Harder

Theses and Dissertations

Ulrich and Flavell (1970) note that although aggression is more a problem today than it has ever been, and although there have been centuries of concern, little has been done to develop effective controls. One conceptual framework for explaining the occurrence and control of aggressive behavior is social learning theory. Bandura (1973) suggests that aggressive behaviors that are reinforced will be strengthened. Several studies with children support this notion (Cowan & Walters, 1963; Davitz, 1952, & Lovaas, 1961). Those aggressive behaviors that are punished or unrewarded will be weakened or eliminated. Hawkins, Peterson, Schweid, and Bijou (1966) suggested that extinction …
