Reproductive Biology Of The Rat Lungworm Angiostrongylus Cantonensis (Metastrongyloidea: Angiostrongylidae), Grace Spatafora Harris

Master's Theses

Twenty rats (Rattus norvegicus) received infective inocula of 5, 10, 20, and 40 third-stage larvae of Angiostrongylus cantonensis. The effects of varying doses of larvae on prepatent period larval production, worm establishment, worm size, and fertility were studied. The aquatic gastropod Biomphalaria glabratta was the experimental intermediate host.

The duration of the prepatent period varied from 37 to 45 days. The shortest prepatent period was observed in animals that received the highest infective inoculum. The prepatent period showed a significant inverse relationship with increasing inoculum size. Larval production increased logarithmically, followed by a plateau phase. The number of larvae per …

Isolation And Characterization Of The Serum Ferroxidase Inhibitor, Melissa Page Calisch

Master's Theses

strong evidence suggests that the serum ferroxidases (ceruloplasmin andferroxidase II) promote the formation of Fe-III transferrin and thereby stimulate the turnover of iron from tissue stores. Ceruloplasmin is the major ferroxidase in human serum; whereas, ferroxidase II accotmts for an increased proportion of the activity in less highly developed animals. A large fold increase in total ferroxidase II activity was observed when both human and rabbit sera were subjected to gel-filtration on sephadex G-200. This indicated that whole serum might contain a potent inhibitor of ferroxidase II. Such an inhibitor has been isolated and purified to homogeneity by a combination …

An Electrophoretic Comparison Of Gene Loci In Etheostoma Nigrum And Etheostoma Olmstedi From The James River Drainage, Virginia, Randall Keith Falls

Master's Theses

As many as five different populations of Etheostoma nigrum and Etheostoma olmstedi have been identified in the James River drainage, Virginia. Genetic variation of these populations was analyzed with starch gel electrophoresis and revealed only three distinct populations. Nine loci encoding five enzyme systems and two loci encoding muscle proteins were examined in tissue homogenates. All populations were monomorphic with the exception of the esterase-3 (Est-3), phosphoglucomutase (Pgm-1) and phosphoglucose isomerase (Pgi) loci. Two alleles of Est-3 exhibited activity in the homozygous and heterozygous conditions. Pgm-1 occurred as two alleles with a high degree of heterozygosity (46% for E. nigrum …

Capital Punishment : Public Opinion And Abolition In Great Britain During The Twentieth Century, Carol A. Ransone

Master's Theses

Some form of capital punishment has been practiced for as long as there has been recorded history. Early laws were generally harsh and failed to consider the impact of crime on society. In 621 B.C. the Code of Dracon recorded the laws observed in Athens. The Code of Dracon revealed that almost all offences were punishable by death. Two centuries later a more humanitarian attitude was expressed in Greece. Plato believed in the segregation and reform of the criminal rather than his execution.

In England the death penalty for felony convictions was traced to the reign of Henry I. It …

The Effects Of Osmotic Stress On Sodium, Potassium, And Chloride Metabolism In The Mongolian Gerbil, Meriones Unguiculatus, Mark William Hagood

Master's Theses

The effects of osmotic stress on sodium, potassium, and chloride metabolism and the physiological mechanisms governing these ions were studied in the Mongolian gerbil, Meriones unguiculatus. Animals were subjected to dietary regimens ranging from sodium-free to high-sodium diets for sixty days. Results indicate the gerbils were not physiologically stressed by the imposed diets. Apparently the animals regulate ion metabolism via intrarenal mechanisms and pituitary antidiuretic hormone while behavior and adrenal cortical activity are insignificant.

Meredith's Women In Time : Diana Merion And Clara Middleton, Dana Sims Brewer

Master's Theses

In The Egoist and Diana of the Crossways, George Meredith joins the ranks of Mary Wollstonecraft and John Stuart Mill in a slowly evolving cultural crusade to gain self respect, dignity, and independence for Victorian women.

Field Dependence As A Factor In Eyewitness Accounts, Charlotte Sue Lerch

Master's Theses

The purpose of this study was to investigate the relationship between field dependency and performance on an eyewitness task. Sixty four college students participated in the experiment. Subjects were divided into two groups, field dependent and field independent, based on their scores on the Group Embedded Figures Test (Witkin et al. , 1971). All the subjects viewed a series of slides depicting a wallet snatching incident and, after completing a short, filler activity, filled out a thirty item questionnaire on the slides. After a two day interval, the subjects read a summary paragraph of the wallet snatching incident. This paragraph …
