Bio-Oxidation Of A Model Voc In Air, Jeong Seop Shim
Theses
This study was performed to find a satisfactory regime of operation for the vapor phase bio-oxidation of ethyl alcohol, a model volatile organic compound (VOC), in a specially designed bioreactor. Ethanol was selected as a model compound representing bakery oven gas pollution. A spirally wound bioreactor module was used within which was immobilized a mixed bacterial culture from aerobic sludge. The activated sludge from municipal wastewater treatment plants readily attached with no pretreatment on the surface of the spiral biosupport which is a polymeric sheet.
The parameters studied were air flow rate and inlet concentrations of ethanol. Ethanol was injected, …
Study On The Remediation Of Organic Soil Contaminated With Polychlorinated Biphenyls Using A Variable Frequency Microwave Furnace, Lili Zou
Theses
The development of new and innovative remediation technologies for soil contaminated with Polychlorinated Biphenyl (PCB) is necessary to fulfill the need of cleanup of contaminated sites. In the past eight years the Laboratory for Microwave treatment as Hazardous Substance Management Research Center has investigated the use of Microwave energy to remediate contaminated soils. A major drawback of using single frequencies of the microwave range is the non-uniformity of the electromagnetic field. In this thesis a Variable Frequency Microwave Furnace (operating between 2.40 and 7.50 GHz) is used to improve the uniformity of the field. A new method is used to …

A River Ran Through It... : The Cultural Ecology Of The Santa Clara Valley Riparian Zone, Erin M. Reilly
Research Manuscript Series
This study addresses the nature of human interaction with the riparian environment in the Santa Clara Valley over time. This is not a new anthropological theme. Literature dates to 1863 The Earth as Modified by Human Action, by George P. Marsh); cultural ecologist Betty J Meggars stated: "The relationship- of culture to environment is one of the oldest problems in the science of anthropology ... "(Meggars, 1968:19); and, anthropologist Alfred Kroeber said: "no culture is wholly intelligible without reference to the nonculture, or so-called environmental factors with which it is in relation and which condition it "(Kroeber 1906:297).

Resonance Raman Investigation Of The Radical Cation Of 1,3,5-Hexatriene, Tamas Keszthelyi, Robert Wilbrandt, Robert J. Cave, Jenifer L. Johnson
Resonance Raman Investigation Of The Radical Cation Of 1,3,5-Hexatriene, Tamas Keszthelyi, Robert Wilbrandt, Robert J. Cave, Jenifer L. Johnson
All HMC Faculty Publications and Research
The resonance Raman spectrum of the 1,3,5-hexatriene radical cation generated by v-irradiation in a Freon glass is reported. The spectrum is excited at 395 nm in resonance with the second absorption band. Identical spectra are obtained from ionized (E)- and (Z)-1,3,5-hexatriene. The presence of more than one rotamer has to be assumed to account for all the observed resonance Raman bands. The bands are assigned to a mixture of the two rotamers, calculated at lowest energy, the ttt an tct rotamers, on the basis of ab initio ROHF/6-31G calculated harmonic frequencies. The spectrum indicates that …
The Arctic Environmental Protection Strategy: A Comparison With The Approach Of The Unep Regional Seas Programme, Vinton Valentine
The Arctic Environmental Protection Strategy: A Comparison With The Approach Of The Unep Regional Seas Programme, Vinton Valentine
Marine Affairs Theses and Major Papers
In the past two decades, there has been a rise in the number of multilateral regional agreements for marine environmental protection. A large proportion of these regional agreements are the result of the United Nations Environment Programme's (UNEP) Regional Seas Programme. While there are thirteen regional seas under the Programme, the Arctic Ocean is not, and never was, one of them. In describing concerns regarding the Arctic environment and approaches to handle them, a number of commentators have proposed the application of UNEP Regional Seas Programme approach to the Arctic region. However, despite an attempt from the Inuit Circumpolar Conference …
Fresh Water To Arabia By Vlcc-Fact Or Folly?, Joseph P. Power
Fresh Water To Arabia By Vlcc-Fact Or Folly?, Joseph P. Power
Marine Affairs Theses and Major Papers
Population growth, industrial development and the esoteric goals of national self-sufficiency in water and food propels the arid nations of Arabia in a voracious scavenge for alternative resources of fresh water as depletion and contamination of the natural aquifers have reached critical proportions. Desalination of sea water is currently the preferred alternative source of fresh water. Recent misgivings concerning the antroprogenic discharge of desalination effluent (i.e. high temperature and high saline water) into the semi-enclosed, epicontinental waters of the Arabian Gulf question the sustainability of this process. Demonstrable deleterious affects of such a process on the marine ecosystem of the …
The Persian Gulf Oil Spill: A Case Study Of Emerging International Law On Environmental Damages During Hostilities, Esther J. Mcclure
The Persian Gulf Oil Spill: A Case Study Of Emerging International Law On Environmental Damages During Hostilities, Esther J. Mcclure
Marine Affairs Theses and Major Papers
During the 1991 Persian Gulf War, the retreating Iraqis caused the deliberate discharge of six million barrels of oil into the shallow waters of the Persian Gulf. The immediate impact on the ecosystem was dramatic, and, because of the intense media coverage of the conflict, highly visible to the American public. The spill popularized the term 'ecoterrorism' and raised serious questions about the applicability of international law to the situation. There are numerous conventions that seek to establish standards of due diligence for the prevention of accidental pollution and to impose civil liability on those who damage the environment, but …
Considerations For Evaluating Ultraviolet Radiation-Induced Genetic Damage Relative To Antarctic Ozone Depletion, Deneb Karentz
Considerations For Evaluating Ultraviolet Radiation-Induced Genetic Damage Relative To Antarctic Ozone Depletion, Deneb Karentz
Biology Faculty Publications
Springtime ozone depletion over the Antarctic results in increased UVB in local marine environments. It has been established that decreases in primary productivity occur with decreases in ozone concentrations, but the impact of increased UVB on the functioning and stability of the ecosystem has not yet been determined. Very little has been done to evaluate the potential for genetic damage caused by the increase in UVB, and this type of damage is most significant relative to the fitness and maintenance of populations. An essential problem in evaluating genotoxic effects is the lack of appropriate techniques to sample and quantify genetic …

Fisheries Research Report No 101 - The Big Bank Region Of The Limited Entry Fishery For The Western Rock Lobster, Panulirus Cygnus, C F. Chubb, E H. Barker, C J. Dibden
Fisheries Research Reports
The Big Bank region lies to the north of the Abrolhos Islands zone of the limited entry western rock lobster fishery (Zone A) close to the edge of the continental shelf. Since 1986/87 the catches from this previously lightly exploited region have become important to a number of rock lobster fishermen operating in the northern (A and B) zones.
Fishing at Big Bank occurred predominantly in January and February of each season, however, recently introduced regulations have closed the region to fishing until February 10 each year. A maximum of 83 boats have operated in the region catching up to …

Comparison Of Dietary Overlap Between Allopatric And Sympatric Geckos, Paul D. Klawinski, R. Kathryn Vaughan, Daniel Saenz, William Godwin
Faculty Publications
Two gecko species, Hemidactylus turcicus and Cyrtopodion scabrum, have been introduced into the Port of Galveston, Texas. While H. turcicus has been established for a longer period of time, the relatively recent introduction of C. scabrum near the entrance of the Port has apparently led to the displacement of H. turcicus in that area. This has resulted in a distribution in which the two populations’ are largely allopatric except for a narrow band of sympatry at the periphery of each of their ranges. We examined stomach contents of both species in allopatry and sympatry in order to determine if …

Land Use Patterns In Relation To Lake Water Quality In The Long Pond, North Basin Watershed, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College
Colby College Watershed Study: Long Pond, North (2006, 1994)
Long Pond has been used recreationally over time for boating, fishing and swimming. Additional uses include drinking water and various types of waste disposal. In past winters, sawdust from lumber mills has been placed on the ice that covers the north basin of Long Pond (Ed Mayer pers. comm.). This may raise total phosphorus levels at depth and could lead to problems in the future. Activities which raise organic sediments input into the lake should be avoided.
A major purpose of our study was to analyze the present water quality of Long Pond, North Basin, including the biotic and abiotic …

Obtaining Assistance To Control Wildlife Damage, Philip S. Gipson, Russel F. Reidinger Jr.
Prevention and Control of Wildlife Damage Handbook
The Wildlife Society (TWS) policy statement for wildlife damage control (1992) states: “Prevention or control of wildlife damage . . . is an essential and responsible part of wildlife management.” The role of wildlife damage control in our society is changing and so is public perception of it. This change is recognized among wildlife managers and researchers. Efforts are under way to make the wildlife damage control profession more responsive to concerns of society. Formal petition for the establishment of a Wildlife Damage Working Group within TWS was made to the Wildlife Society Council on March 21, 1993 and the …

Eagles (Haliaeetus leucocephalus and Aquila chrysaetos) are the largest bird of prey in North America. Golden eagles in North America occur in greatest numbers from Alaska southward throughout the mountain and intermountain regions of the West and into Mexico. Eagles frequent a wide variety of habitats. Although regional and seasonal differences in food habits exist, golden eagle prey consists mostly of small mammals such as jackrabbits, cottontails, prairie dogs, and ground squirrels. Eagle courtship displays consist of a series of “roller coaster” dives and other aerial maneuvers. Juvenile golden eagles leave the nesting territory as early as May …
