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the comparisons and contrasts of the conditional stimuli's (CS's) actions with those of morphine in morphine withdrawn rats.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 …

An Investigation Of A Simulated Spatial Technique As A Measure Of Interpersonal Distancing Behavior, Max C. Alovisetti

Open Access Dissertations

Due to ease of administration, many studies in the area of interpersonal distancing behavior have used simulated spatial measurement techniques. These have generally included manipulations of inanimate representations of people. They have often been assumed to be equivalent to behavioral measures of interpersonal distancing. The present investigation's major objectives were to determine the followings (1) extent to which a simulated spatial measure of interpersonal distancing is related to actual behavior; (2) whether interpersonal distancing can be understood in terms of a social learning model; (J) whether personality variables are related to a simulated spatial measure of interpersonal distancing; and (4) …

The Transport And Fate Of Hydrocarbons In Benthic Environments, Paul David Boehm

Open Access Dissertations

Dissolved organic matter (DOM) in sea water solubilizes certain classes of hydrocarbons (Boehm, 1973). Several chemical and biological consequences of this solubilization phenomenon were explored, Experiments on the solubility behavior of No. 2 fuel oil showed that hydrocarbons can be dispersed in water in a soluble, a solubilized (colloidal micelles), and a particulate (accommodated) state. A fractionation of hydrocarbon mixtures (e.g., fuel oil) in sea water occurs due to the differences in the solubility behavior of the various classes of hydrocarbons within the mixture.

Just as DOM promotes saturated hydrocarbon solubility, (i.e., the passage of a filter), solubilization by DOM …

A Methodology For The Determination And Communication Of Requirements For An Information Processing System, Carl Allen Singer

Open Access Dissertations

A Requirements Statement Methodology is developed and coupled with a solution to the database design problem. The need for the Requirements Statement Methodology is discussed with the viewpoint of management texts and systems design guidelines. The methodology is developed using forms, computer generated forms, a data dictionary and interactive dialogue. A detailed explanation of PSL (the Problem Statement Language) and PSA (Problem Statement Analyzer) in the context of the Requirements Statement Methodology is presented. A formal discussion of data base design, specifically record and set design, appears. A theoretical model to solve record design is developed and a hueristic and …

Hydrocarbon Analysis Of Surface Seawater And Beach Sand By Infrared Absorption Methods, Wai-Ping Teresa Lee

Open Access Dissertations

Qualitative and quantitative measurements of hydrocarbon contents in the marine environment are very important because of their persistence and the possible toxicity to all aquatic organisms A rapid method for analyzing hydrocarbons in marine surface estuarine waters and beach sands was developed Infrared spectroscopy was employed as the main analytical tool for both qualitative and quantitative determination of. hydrocarbons found in the marine environment. In addition to infrared spectroscopy, gas chromatography was also used in some parts of this study for characterizing the samples. Thin-layer chromatography was used to separate the sample to its separable fractions according to different polarities. …

Particulate Matter In Surface Seawater: Sources, Chemical Composition, And Affinity For The Sea-Air Interface, Gordon T. Wallace Jr.

Open Access Dissertations

An adsorptive bubble separation technique was used to examine the ability of bubbles to transport particulate matter in surface seawater samples. A substantial fraction of the particulate organic carbon (POC) and particulate organic nitrogen (PON) could be recovered in the froth generated by this technique from both estuarine and open-ocean surface waters. Recovery values were lower in samples taken during periods of high productivity. C/N ratios of the particulate matter recovered in the froth were generally not significantly different from the particulate matter not recoverable by this technique. Budget calculations indicated that there was no significant conversion of dissolved organic …

Ecology Of Parathemisto Libellula And P. Pacifica (Amphipoda: Hyperiidea) In Alaskan Coastal Waters, Bruce L. Wing

Open Access Dissertations

The planktonic amphipods Parathemisto libellula and P. pacifica coexist in coastal waters from southeastern Alaska (56° N) to the south-eastern Chukchi Sea (70° N). Observations on distribution, reproductive cycles, diets, metabolism, and starvation tolerance contribute to understanding this case of congeneric coexistence.

Samples were collected monthly from September 1969 to October 1970 in southeastern Alaska, from May to September 1969 in the southeastern Bering Sea, and in September-October 1970 in the southeastern Chukchi Sea. Respiratory metabolism and starvation tolerance were studied in winter-caught amphipods from southeastern Alaska.

Both species consistently occurred above 300 min southeastern Alaska. In the southeastern Bering …

The Effects Of Self-Imposed And Externally Imposed Rewards Of Children's Intrinsic Motivation, Douglas Lee Schooler

Open Access Dissertations

An experiment was designed to compare the effects of self-imposed, externally imposed, and a no reward control, on children's interest in both a high and low listening task. A hypothesis grounded in personal control theory predicted that self-imposed rewards would increase subsequent task interest, whereas externally imposed reward would interact with initial task interest and would yield a decrease in interest for the high interest task and an increase in interest for the low interest task. A secondary hypothesis predicted that children would self-reward with greater magnitude on the low interest task. The subjects, 48 boys and 48 girls from …

Analysis Of Chilean Fisheries Expansion Alternatives, Luis Alberto Adriasola

Open Access Dissertations

This dissertation investigates the expansion of the Chilean fisheries focusing on the processing and marketing activities for seven fish species that represent over 90% of the catch and for two groups of the remaining fish species. A review is made of the current condition of the Chilean fisheries, its expansion potential and some possible expansion alternatives. It is established that there exists an ample potential for the expansion of the catch and physical production of fishery commodities. A model is developed to characterize the economic system formed by the fisheries extractive and related activities and assess the profitability of investment …
