Facilitation Of Fear Reduction Following Electrical Stimulation Of The Brain In Rats, William A. Pacitti

Open Access Dissertations

This study assessed the efficacy of positive electrical stimulation of the brain in counterconditioning fear in 100 albino laboratory rats. A parametric investigation was undertaken in which fear was conditioned through presentation of electric foot shock and then reduced through response prevention, in combination with different types of electrical stimulation of the brain. The basic measure of fear was the Conditioned Emotional Response (CER), as seen in the suppression of licking behavior.

Electrical stimulation of the brain (ESB) has been used to effectively reduce active avoidance responding, another measure of conditioned fear, and its effects resemble closely those obtained when …

Sedimentary Geochemistry Of Hydrocarbons From Narragansett Bay, Rhode Island: Incorporation, Distribution And Fate, Terry Lee Wade

Open Access Dissertations

Determining the impact of petroleum pollution in estuarine environments is essential, due to their biological importance. The Marine Ecosystems Research Laboratory (MERL) offers a unique opportunity to investigate the geochemical fate and biological effects of chronic petroleum addition to the productive Narragansett Bay estuary. The two main objectives of this research were to determine: (1) the geochemical distribution of hydrocarbons for Bay sediments, and (2) the mode of incorporation, distribution and fate of saturated hydrocarbons in the MERL ecosystem sediments.

The concentration of hydrocarbons (saturated, aromatic, biogenic, and anthropogenic) and chlorinated hydrocarbons (chlordane, DDT, and PCB’s) in mid-Narragansett Bay was …

Closedmindedness As A Positive Behavior, Herbert Wax

Open Access Dissertations

The purpose of this study was to examine how males and females who were categorized as either open or closedminded would respond to a Slide Show followed by a True/False Test and the Human Assistance Distance Scale (RADS) constructed for this experiment.

A group of subjects took Rokeach's Dogmatism Scale which differentiated them into openminded and closedminded groups. Both groups were matched by sex. They then viewed the Slide Show which consisted of low and high stress pictures, taken from a variety of sources. The subjects were then given a True/False Test related to factual content of the slides. They …

Effect Of Conditional Stimulus On Morphine Withdrawal Signs In The Rat, Richard B. Drawbaugh

Open Access Dissertations

The present investigation was undertaken to demonstrate the comparisons and contrasts of the conditional stimuli's (CS's) actions with those of morphine in morphine withdrawn rats. The study shows that specific stimuli altered behavioral and physiological withdrawal signs such as: hypothermia, shakes, ptosis, piloerection, writhing and aggression. Also, one stimulus was able to effect two biochemical measures (blood glucose and striatal homovanillic acid) similar to the action of morphine.

Rats were given two equally spaced injections of morphine sulfate paired with different stimuli (bell, drug, oil of anise, saccharin). The stimuli were paired with an injection for 15-25 days. Twenty-four hours …

Time And Frequency Domain Representations Of The Left Ventricle: Theoretical And Experimental Results, Dennis James Arena

Open Access Dissertations

A frequency domain and a time domain model of the left ventricle are described in this work. These representations provide insight into the function of the healthy left ventricle and show how ventricular function may be altered by heart disease.

In developing the frequency domain representation of the left ventricle, the flow and pressure waveforms generated by the left ventricle were described as superpositions of sinusoidal oscillations at different frequencies. Flow and pressure waveforms were obtained experimentally at two different left ventricular afterloads. The two different afterloads were obtained utilizing an intraaortic balloon. The left ventricle was modeled by an …

An Empirical Investigation Of An Existential Theory As It Appears To The Elderly: The Will To Live, Ann M. Varna Garis

Open Access Dissertations

The purpose of the present study was to investigate the Will to Live concept as it applies to the elderly. This was accomplished by exploring the relationship among the variables of Purpose in Life; Locus of Control; Depression; and a self-rating Will to Live scale. These are variables which, according to the literature, could be expected to be major components of the Will to Live concept. The subjects for this study were 63 volunteers, ranging in age from 60 to 95, taken from different housing settings, nursing homes; apartments for the elderly; and private homes in the community. In order …

Atmospheric Pathways Of The Phosphorus Cycle, William F. Graham

Open Access Dissertations

The flow of particulate phosphorus through the atmosphere has been studied: The goal of the work was to deduce the magnitude and direction of the fluxes of phosphorus through the atmosphere and to identify the sources of this phosphorus. Samples of atmospheric particulate matter were collected at urban, rural, and remote continental sites, at remote island sites, and on ship-board over the Atlantic and Pacific Oceans Samples of precipitation and. dry fallout were collected at sampling sites at Narragansett, R.I. and Bermuda. Total phosphorus was determined on both the samples of atmospheric particulate matter and the deposition samples. In addition, …

The Isolation And Partial Characterization Of The Dissolved Organic Matter In Seawater, Richard Alan Kerr

Open Access Dissertations

The significance of dissolved organic matter (DOM) in the biological and chemical processes of the sea has been a much debated subject. Isolation of the trace amount of DOM in large volumes of seawater would permit further characterization of its pertinent chemical properties and an assessment of its role in marine processes, such as the speciation of trace metals, A variety of techniques have been used to isolate as large a representative portion of DOM as possible without alteration or contamination. A number of DOM samples have been isolated using adsorption and filtration techniques and partially characterized, but they have …
