Chromatographic Methods Development For The Charcterization Of Phytopharaceutical Materials, Melanie Levesque

Theses

The increased popularity of alternative medicine treatments has prompted resurgence in the use of traditional herbal remedies. Among this vast number of herbs, ginseng is purchased by a considerable number of consumers; especially three species: Panax ginseng, Panax quinquefolium, and Eleutherococcus senticosus. Many of the physiological effects claimed by ginseng manufacturers tend to mimic those of central nervous system stimulants. This led to the purpose of this research, which was to develop an HPLC chromatographic method in order to determine if any specific CNS stimulants are within ginseng supplements. Specifically we found a series of CNS stimulants, methylxanthines (caffeine, theophylline, …

Studies On The Occurrence Of Fluoride In Some Food Samples, Taghreed Ali Abdullah Al-Habshi

Theses

In recent years, the amount of fluoride in biological samples, drinking water and in fluoride containing food or feedstuffs has generated considerable interest. Hence the determination of fluoride is becoming increasingly important due to its implications for environmental health. Fluoride is considered to be amongst the most phytotoxic of the more common pollutants. In response to that extensive research has been made to improve the determination of trace amounts of fluoride through developing different analytical methods. The application of these various analytical methods for fluoride ion determination in water and food samples has gained an enormous interest.

Prohibiting Conduct, Not Consequences: The Limited Reach Of The Migratory Bird Treaty Act, Benjamin Means

Michigan Law Review

Dissatisfied with the protection afforded wildlife by more recent environmental laws, some environmentalists seek to reinterpret one of the oldest federal environmental laws, the Migratory Bird Treaty Act (MBTA). Long understood simply to regulate hunting, the MBTA makes it illegal to "take" or "kill" migratory birds without a permit. The MBTA imposes strict liability for a violation. A heady combination of strict liability, criminal penalty provisions, and vague language, the MBTA appeals to those seeking to control land use activity. Some environmentalists advocate an interpretation of the MBTA that, contrary to legislative intent and 80 years of enforcement practice, would …

Biochemistry Of Hemolysin Toxin Activation By Fatty Acylation: Characterization Of An Internal Protein Acyltransferase, Michael S. Trent

Electronic Theses and Dissertations

Hemolysin toxin produced and secreted by pathogenic Escherichia coli is one of a family of cytolytic, structurally homologous protein toxins known as RTX (repeats in toxin) toxins. RTX toxins are products of a gene cluster, CABD . The A gene product, nontoxic hemolysin (proHlyA) is made toxic by post-translational fatty acylation of two internal lysine residues. HlyC, C gene product, is essential for acylation, and acyl-acyl carrier protein (ACP) is the acyl donor. HlyB and HlyD are involved in secretion of the toxin. HlyC was thought to serve as an internal protein acyltransferase and remained uncharacterized until now. ProHlyA and …

Chinese Characters As Sources Of Design Of Furniture, Han-Lim Wee

Theses

This thesis is an exploration of possibilities of the translation of Chinese characters into furniture. It is not just the two dimensional image of the character that I wish to interpret into three dimensions, but I intend that the functions and uses of the furniture are to be the meaning of the word. The final pieces are intended to be recognized as to their meaning by anyone literate in Chinese character forms. Furniture that has both form and meaning will create new possibilities for furniture's role in the environment by having this extra dimension.

Winter Movements And Habitat Use Of Northern Saw-Whet Owls At Assateague Island, Maryland, John Beaudry Churchill

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ten Northern Saw-whet Owls were radio-tracked over two winters (1996 and 1997) at Assateague Island, Maryland. I used the fixed kernel method to calculate home range estimates for seven owls. Ninety-five percent home range sizes averaged 122.9 ha (range from 39.7--261.9 ha) but varied in size and shape. I also calculated adaptive kernel, harmonic mean, and minimum convex polygon home ranges for comparison of these methods. Habitat composition in 30% home ranges was compared with 95% home ranges and 30% and 95% home ranges were each compared with composition of the entire study area using compositional analysis.;Roost site characteristics were …

Modulation Of Aging Process By Diet And Crosslinking Inhibitor And Their Effects On Production In Poultry, Muhammad Iqbal

Graduate Theses, Dissertations, and Problem Reports (ETD)

The factors which influence the age-related decline in production performance and increases in meat toughness in broiler breeder hens are poorly understood. We have hypothesized that the elevated plasma concentration of glucose contributes to the nonenzymatic attachment of glucose to proteins, and generates glycoxidation crosslinks in tissues which can ultimately impair function, is responsible for loss of production. One such crosslink, pentosidine, is an established indicator of both glycative and oxidative tissue damage in mammals. Specifically, the role of diet restriction (DR) and a nucleophilic hydrazine compound, aminoguanidine (AG), a crosslinking inhibitor, were examined on tissue crosslinking with the view …

Acquisition Of Observing Responses With Delayed Conditioned Reinforcement, Gregory A. Lieving

Graduate Theses, Dissertations, and Problem Reports (ETD)

Six pigeons were trained to key peck for 3-s access to mixed grain on a multiple variable-interval 60-s extinction schedule. The schedule then was changed to a mixed variable-interval 60-s extinction schedule. Simultaneously, a treadle was introduced into the chamber. For 3 pigeons, the stimulus correlated previously with the variable-interval schedule could be produced by treadle pressing (i.e., an observing response) on a tandem fixed-ratio 1 differential-reinforcement-of-other-behavior 10-s schedule. For the other 3 pigeons, no contingency was implemented for treadle pressing. Treadle pressing was established equally in the presence and absence of the observing contingency. The results did not extend …

Fixed -Interval Timeout From Avoidance With Humans, Janet L. Emmendorfer

Graduate Theses, Dissertations, and Problem Reports (ETD)

On fixed-interval (FI) schedules of reinforcement, humans and other animals often have different response patterns. For example, the pattern typically associated with animals is the scallop: a pause followed by a gradual acceleration in responding. Humans generally show terminal-minimum (i.e., pause until the end of the interval, then make 1 or 2 responses) or constant-rate patterns. There have been numerous investigations of the variables that control such different response patterns. The most common variables in those studies are instructions, verbal ability, response cost, concurrent tasks, and food and points as reinforcers. The purpose of the present experiments was to investigate …

Cellular Mechanisms Of Altered Neuronal Sensitivity In The Genetically Epilepsy-Prone Rat, Lance Russell Molnar

Graduate Theses, Dissertations, and Problem Reports (ETD)

The genetically epilepsy-prone rat (GEPR) is an animal model of epilepsy which exhibits deficits in GABAergic neurotransmission in a variety of brain regions. However, the underlying cause for this deficit has yet to be described. The present studies were therefore performed in order to elucidate the mechanism(s) underlying this GABAergic deficit. To accomplish this task, electrophysiological recordings of Purkinje neurons in sagittal slices of the cerebellar vermis were performed. The initial aim was to compare the basic electrical membrane characteristics of Purkinje neurons from GEPR and control animals using standard intracellular recording techniques. These studies indicated that there is no …

Determining Perspectives Of Selected Disciplines Concerning The Nature Of Technology Within Classic Literature, Bryan Calvin Maser

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this research was to identify if there was a significant difference between the perspectives of selected disciplines with regard to the nature and history of technology. A content analysis of classic literature from multiple disciplines to determine perspectives concerning the nature of technology served as a basis for the development of a general semantic differential instrument. The instrument was administered to a given population yielding a conceptual scoring of perspectives. Scored concepts were then cross referenced to respective disciplines to determine if the degree of difference between disciplines was statistically significant.

Holmes And The Romantic Mind, Anne C. Dailey

Duke Law Journal

Oliver Wendell Holmes, Jr. is perhaps best known for his "tough-minded" jurisprudence based on objective standards of reasonableness. Scholars have traditionally understood Holmes's jurisprudential outlook as fundamentally behavioristic. Professor Dailey challenges that understanding, revealing the importance of Romantic psychology in Holmes's major writings. His outlook, she argues, was shaped by his belief in unconscious motivations, imagination, irrationality and instinctual drives. Rather than simply characterize Holmes as a "Romantic," Professor Dailey draws out the conflict in his thought, illuminating his struggle to develop an empirical approach to law that could also account for the depth and complexity of human nature.
