Electrochemical Investigations Of The Mechanisms Of Reduction Of Benzaldehyde Compounds In Sulfolane, Neal Russell Armstrong

Chemistry and Chemical Biology ETDs

The mechanisms of the reduction of benzaldehyde and several sub­stituted benzaldehydes in the dipolar, aprotic solvent sulfolane, have been investigated. A combination of cyclic voltammetry, transmission spectroelectrochemistry and ring-disk voltammetry was used in this study. Cyclic voltammetric studies indicated that the one-electron benz­aldehyde reduction was followed by a dimerization of the radical anion intermediate to the pinacol. The reduction peak potentials of the benzaldehydes were cathodically shifted in sulfolane compared to values obtained in aqueos media. This indicates an increase in the benzaldehyde reduction energy in the aprotic solvent. The rate of the following chemical reaction was also slower than …

Hunting By Expectation Or Optimal Foraging: A Study Of Patch Use By Chickadees, John Krebs, John Ryan, Eric Charnov

Biology Faculty & Staff Publications

When a predator exploits an environment in which food is patchily distributed, it has to continually make the decision of how long to stay in a patch. In this paper we examine this question using black-capped chickadees foraging in a large aviary for small pieces of mealworm hidden in artificial pine cones. The results of our experiments show the following: (a) when the birds encounter a long sequence of patches (groups of pine cones) each containing the same number of prey, they do not learn to expect a fixed number of prey per patch (Gibb's hypothesis of hunting by expectation); …

Studies On The Structural Polypeptides Of Bacteriophage N1, Jeffry J. Leary

Biology ETDs

The structural proteins of Micrococcus lysodeikticus bacteriophage N1 were studied by SDS-urea polyacrylamide gel electrophoresis. Electrophoretic analysis of highly purified virions revealed that N1 phage is composed of six structural polypeptides which were designated VP1 through VP6. Molecular weights of the virion polypeptides were estimated to be 103,000 (VP1), 76,000 (VP2), 66,000 (VP3), 51,000 (VP4), 26,000 (VP5), and 16,750 (VP6) daltons. Quantitative analysis of electropherograms of N1 indicated that VP4, VPS, and VP6 are major components of the virion representing 46%, 29%, and 19% of the weight of the virion protein, respectively. The three minor polypeptides VP1, VP2, and VP3 …

Reproductive Status Of Alligator Juniper In Bandelier National Monument, New Mexico, Graham A. Mark

Biology ETDs

The primary object of this study was to determine the reproductive status of Juniperus deppeana Steud. In Bandelier National Monument, New Mexico. Due to the apparent scarcity of seedlings and young trees, eventual local extinction seemed likely.

Information about the population—its distributions in space and time, its fecundity and mortality rates—was gathered in the Monument. This, together with reported demographic traits of Juniperus spp., indicates that reproduction has indeed recently declined. However, due to the longevity of its members, the population could withstand at least a century of no reproduction before becoming seriously endangered.

Since reproduction has been generally poor …

Isolation Of Hypoxanthine-Guanine Phosphoribosyl Transferase Deficient Mutants In A Mammalian Cell Line, Winston M. Sanford

Biology ETDs

The isolation of hypoxanthine-guanine phosphoribosyl transferase deficient mutants of Swiss mouse fibroblast cells was accomplished by exposure of large numbers of normal cells to the toxic antimetabolic agent 8-Azaguanine. Cell lines resistant to 0.1, 0.5 and 1.0 μg/ml of 8-Azaguanine were obtained. Enzyme studies of these cell lines revealed an inverse correlation between the level of resistance to 8-Azaguanine and the activity of the hypoxanthine-guanine phosphoribosyl transferase enzyme. One exceptional mutant has been isolated with a resistance to 8-Azaguanine and an enzyme activity two-fold higher than the parent cell. These mutants are discussed in terms of genetic and biochemical defects …

Human Sperm Antigens And Antisperm Antibodies, Carol K. Dudley

Biology ETDs

An immune response to spermatozoa may result in the production of autoantibodies to sperm. Most studies of antisperm antibody have depended on sperm agglutination or sperm immobilization which only detect antibodies reacting with cell surface antigen. In the study reported here indirect immunofluorescence was used to examine antisperm antibodies to all components of sperm in vasectomized males. These antibodies were used to study the nature of sperm­specific antigens, located in subcellular regions of the human spermatozoa. The incidence of antisperm antibodies in vasectomized patients rises from 61% before surgery to 90% nine months after surgery. The antibodies present before surgery …

On The Effects Of Reduced Competition Between Species Of Eleutherodactylus., Kirkland Lee Jones

Biology ETDs

To elucidate the changes in the trophic and microhabitat portions of the niche under various degrees of competitive pressure, four species of Eleutherodactylus were studied on five Caribbean islands. Approximately 100 specimens of each species occurring on each island were collected. Five measurements were used to characterize the microhabitat at the collection site. Five morphological measurements were taken from each specimen. All stomach contents were measured, counted, and categorized. Feeding rates were obtained from stomach contents and direct observation.

Agonistic Behaviour In Gila Woodpeckers, Gene L. Brenowitz

Biology ETDs

Agonistic behaviour of Gila Woodpeckers (Centurus uropygialis), including vocalizations, visual displays and other related behaviours, is described. Aggressive interactions with both con- and hetero-specifics were analyzed by stochastic processes. Results indicate that Gila Woodpeckers are far less aggressive than qualitative descriptions suggest and reasons for this discrepancy are presented.

The ecological correlates of Gila Woodpecker aggression were investigated and it appears that most aggression is related to defense of areas both intraspecifically and interspecifically. The effects of the two types of territoriality on the distribution of the species involved were compared and found to be significantly different. A model is …

A Study Of The Enteric Bacterial Population Of The Rio Grande From Cochiti Dam To Bernalillo, New Mexico And Of The Water Systems Of Cochiti, Santo Domingo And San Felipe Villages, Linda K. Fogleman

Biology ETDs

A bacterial survey of fecal coliforms, fecal streptococci, Arizona and Salmonella was made of the waters of the Rio Grande, its adjoining canals and ditches, and of the well water of three pueblos along the Rio Grande in New Mexico. The river and ditch survey consisted of sampling 11 sites from Cochiti Bridge south to the Bernalillo Acequia at Bernalillo, and took place between September, 1971 and November, 1972. Water was collected from six sites in Cochiti Village, five sites in Santo Domingo Village, and seven sites from San Felipe Village between May 25, 1972 and November 14, 1972. Six …

A Spectrographic Analysis Of Pinon Jay Vocalizations, Lyle Rae Berger

Biology ETDs

Vocalizations and behavior of banded pairs of adult Pinon Jays were recorded during 1972. Jays were housed in large outdoor aviaries. Fifteen distinct vocalizations were isolated in this study. During 1973 individual adult Pinon Jays were observed, and their vocal responses to other individuals were recorded under various circumstances in an attempt to quantify the functions of the calls iso­lated in the initial study. Six pairs of Pinon Jays were tested in this manner. A wild flock of unhanded Pinon Jays also was observed during 1972 and part of 1973.

The fifteen Pinon Jay vocalizations were examined with the aid …

An Analysis Of The Change In Contemporary Art Sensibilities In The Late 1960'S., Charles A. Hagen

Art & Art History ETDs

The rigorously formal aesthetics professed by the dominant Minimalist style of contemporary art during the early and middle years of the past decade was replaced beginning in the late 1960' s by a more humanistic aesthetic. Minimalism was in turn followed by a more elusive phenomenon of individual artists and works without a strong unified style. The changed sensibilities of contemporary art originating in the late 1960's is presently the prevailing artistic aesthetic.

Aesthetic issues at each stage of modern art have been raised in successive attempts to explain the sensibilities of evolving modernism. When the Minimalist style was at …
