Interaction Between Nigro-Striatal Lesions And Drugs Affecting Dopamine Receptors, Martin Dennis Hynes

Open Access Master's Theses

Lesioning the nigro-striatal dopamine neuron system produces aphagia and adipsia with an intensity proportional to the size of the lesion. Those rats which received small lesions produced by a 1 mA current for a 15 second duration of the nigro-striatal system initially lost weight and then spontaneously recovered from that loss. Pretreatment with alpha-methyl-para-tyrosine (50 mg/kg) or haloperidol (0.4 mg/kg) given twice a day for a three-day period prior to lesioning facilitated the recovery. When large lesions (2mA for 30 sec) were used to destroy this dopaminergic neuron system, a severe aphagia and adipsia resulting in death occurred in all …

Mechanism And Characteristics Of Drug-Induced Aggression, Gerald Gianutsos

Open Access Dissertations

This research investigated the pharmacological alteration of drug-induced aggression in naive, morphine-dependent and chronically haloperidol treated rats. Naive rats were treated with apomorphine (1.25 - 20 mg/Kg) and aggregated in groups of four for aggression. It was determined that 20 mg/Kg of apomorphine produced maximal aggression, as measured by number of attacks, duration of aggressive posturing and number of vocalizations. Doses less than 5 mg/Kg were without any effect. The neuroleptics, haloperidol and oxyperomide, the narcotic, morphine, and the cholinergic agonist, pilocarpine all reduced apomorphine-induced aggression in a dose dependent manner. Centrally acting anti-cholinergic drugs partially reversed the blockade of …

Phosphorus Exchange At The Sediment-Water Interface Of Selected Narragansett Bay Sediments, Michael J. Petti

Open Access Master's Theses

Narragansett Bay sediments were sampled in the vicinities of Whale Rock, Prudence Island, and Field's Point. The sediments were used in a microcosm study to determine the release and uptake of nutrients from the sediments to the water column above. The nutrient investigated is phosphorus.

It was found that sediments can act as a source or sink of phosphorus to the water column above and affect the productivity of these waters. The release or uptake of phosphorus is a function of complex biological, chemical and physical factors which have been enumerated and described as a function of an exponential rate …

The Energy Future: An Unanswered Question, Jeffrey A. Carver

Marine Affairs Theses and Major Papers

The purpose of the following paper is to examine broadly some of the implications of the energy shortage, in terms of the following: the new kinds of technology being developed to tap alternative energy sources; the relationship between the energy shortage and the soon-to-be-felt shortages of other resources; possible effects of the energy shortage upon efforts to protect the environment; and social implications of the inevitable limitation to economic and population growth, at least on this planet. The paper is presented in two parts. The first will be a brief discussion of the major elements of the problem and a …

International Regulation Of Marine Pollution From Land-Based Sources, Richard Tucker Scully

Marine Affairs Theses and Major Papers

Most of the waste products of human society end up in the oceans and the number and quantities of pollutants entering the oceans have been increasing at exponential rates. Recognition of these trends has resulted in expansion of international environmental attention to include sources of marine pollution other than vessels. Source, in this sense, refers to the pathway through which pollutants reach the sea. Land-based sources accounts for the vast bulk of the pollutants reaching the oceans. Effective protection of the marine environment, therefore, must include regulation of land-based sources of marine pollution.

The Tanker And Ocean Oil Pollution, Raymond Coombs

Marine Affairs Theses and Major Papers

It is now clear that the capacity of the oceans to accept some of the by-products of civilization is limited. The oceans can no longer be the world's sink, it we are to maintain the ecological viability of the biosphere. The dangers of the present situation are compounded by the difficulties in defining "marine pollution." Today's concern with pollution and its effects upon our way of life requires that the impact of ships on the marine environment be considered in order to minimize the risk that waterborne cargoes, particularly petroleum products, present to the ecology.

The Dilemma Of Deep Ocean Mining, Paul W. Dillingham Jr.

Marine Affairs Theses and Major Papers

Mineral substances and materials derived from them, whether in the form of fuels, construction materials, metals for farbication, tools, chemicals, or fertilizers, are the foundation of our technological civilization. The modern industrial civilization depends upon the continued availability of mineral raw materials. The problem is not one of actual scarcity ; the raw materials are there in the ground and in the sea in great supply. The question and the uncertainty is economic; How will these resources be recovered and by whom? This proposition becomes the central force in order to adjust to the new resources climate.

The Port Of Boston: Perspective On A Maritime Dilemma, Louis Edward Cellineri

Marine Affairs Theses and Major Papers

Few in Massachusetts, or even in the metropolitan Boston area, however, understand their Port's past, and few still appreciate its present contributions and sympathize with its struggles and problematic future. Whatever its past fame or present indignities, the excitement of a vibrant, profitable waterfront does not enter into the advocacy and implementation of harbor recreational and residential development plans, with or without commercial activities. This near dismissal of the Seaport's present and potential value in certain circles, only presents another dilemma to those attempting to cope with this veritable maritime bag of worms. But despite all these obstacles, the Port …
