Population Characterization And Feeding Behavior Of A Subtidal Neogastropod, Amphissa Columbiana, Bruce C. Stone Dec 1976

Population Characterization And Feeding Behavior Of A Subtidal Neogastropod, Amphissa Columbiana, Bruce C. Stone

Theses and Dissertations

The neogastropod Amphissa columbiana is found abundantly in subtidal areas of the San Juan Archipelago. Two populations studied were composed of distinct age classes of sexually immature and mature specimens. Reproduction appears to take place in the fall by snails at least two years old. Amphissa is a chemoreceptive scavenger that usually feeds on carrion and on dead and injured animals. Feeding behavior is mediated by chemical attractants from dead and traumatized tissue. An unusual feeding association is formed where Amphissa congregate around feeding predators to share their meals. A specific defense mechanism is deployed by Amphissa especially in response …

The Osteology And Myology Of The Head And Neck Region Of Callisaurus, Cophosaurus, Holbrookia, And Uma, The "Sand Lizards", Douglas Charles Cox Dec 1976

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 Dec 1976

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.

A Study Of Selected Photo Fries Rearrangements, Elwood Lloyd Loveridge Dec 1976

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., …

Potential Diets For Carp Production, Rex Carlton Infanger Dec 1976

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.

Spatial And Temporal Partitioning Between Sympatric Rodents: Zapus And Peromyscus, Emma Bernice Speer Dec 1976

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 Dec 1976

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 …

Computer Model Of A Fast Toroidal Plasma Compression, With Application To The Topolotron, H. Mark Nelson, Keith H. Brown, Charles A. Hart Nov 1976

Computer Model Of A Fast Toroidal Plasma Compression, With Application To The Topolotron, H. Mark Nelson, Keith H. Brown, Charles A. Hart

Faculty Publications

The method is developed for a comuputer sequence which models a fast toroidal theta or screw pinch for a highly conducting axially symmetric plasma. The computer sequence takes into account the self-inductances of the plasma and the external conductors which drive the compression as well as the mutual inductance which electromagnetically couples the two. The computer sequence is divided into three phases: a snowplow compression phase, an adiabatic compression phase, and a crowbarred circuit phase. The computer sequence is applied to a topolotron and an example is given of a magnetohydrodynamic equilibrium geometry for which the plasma surface possesses an …

Indigenismos En El Español Hablado En Santiago, Orlando Alba Oct 1976

Indigenismos En El Español Hablado En Santiago, Orlando Alba

Faculty Publications

En este artículo se busca verificar la vitalidad (o la caducidad) de los indigenismos léxicos que recoge Pedro Henríquez Ureña en su obra El español en Santo Domingo. Se intenta contribuir así al establecimiento de la nómina pasiva de esos indigenismos en la norma de cada estrato sociocultural en la ciudad de Santiago de los Caballeros.

Recent Swiss Immigration Into Nebraska: An Empirical Study, W. Ernst Study Oct 1976

Recent Swiss Immigration Into Nebraska: An Empirical Study, W. Ernst Study

Swiss American Historical Society Newsletter

In the Bicentennial Year it appears fitting that social scientists, especially those with a historical bent and with ties to the fount of immigration into the Western Hemisphere, address themselves to the role played by non-American ethnic minorities in the United States today.
