Pyrolysis And Oxidation Reaction Of 1,2, Dichloroethylene In Ar; Ar And Ch4; Ar, Ch4 And O2 Mixtures, Byung Ik Park

Theses

The thermal reaction of trans-1,2-dichloroethylene (DCEE) in methane and oxygen mixtures in Ar bath gas has been studied in 10.5 mm I.D. tubular flow quartz reactors at I atmosphere pressure, isothermal temperature between 575°C and 1000°C, and times of 0.3 to 2.0 seconds.

The thermal reaction of trans-1,2-dichloroethylene in the gas phase proceeds via unimolecular HCI elimination under the reaction condition of the present experiments. The chain branching C-Cl bond fission reaction is expected to become important at the higher temperature, competing With the HCI elimination.

The decay trans- 1,2- dichloroethylene, intermediates and final product distributions varied in the absence …

Study Of The Leaching Of Pentachlorophenol From Treated Utility Poles, Jingyi Zhang

Theses

Pentachlorophenol ( PCP ) has been used as a preservative in wood industry over 40 years. If new regulations are passed, the disposal of used treated utility poles in landfills could be restricted because of the toxic properties of PCP. This study was undertaken to provide a better understanding of the rates and mechanisms of leaching of PCP from these poles.

Following the initial analytical method development for PCP determination, a study was done to apply and validate the method in a leaching characteristics study of PCP from Douglas Fir and Southern Pine.

The major factors which influence the leaching …

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 …

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, …

Pedogenic Processes In Thick Sand Deposits On A Marine Terrace, Central California, Lynn E. Moody, R. C. Graham

Natural Resources Management and Environmental Sciences

Pedological studies in thick sedimentary sequences are generally limited to the upper few meters. Field investigation of thick (~50 m) sand deposits on an emergent Pleistocene marine terrace in central California showed morphological differences between the solum at the surface and the deep regolith. Based on morphological and geochemical features, four units were identified within the regolith. Two zones of active pedogenesis occur within three of these units. The surficial unit is in Holocene sand deposits (mixed, thermic, Argic Xeropsamments), and has darkened A horizons, a slightly reddened subsoil, and incipient lamellae at the depth of wetting front infiltration. These …

Tourism Professionals Profile: Theme Park Managers, Robert M. O'Halloran, Christopher Siew L. Wong

Hospitality Review

Theme park managers are a unique group of tourism managers. Their perspectives on effective tourism management skills and abilities differ from some public sector tourism managers. The authors present the results of a study focusing on theme park managers and compare these results with those of other tourism manager groups

The Role Of Theme Parks In Tourism, Lou-Hon Sun, Muzaffer Uysal

Hospitality Review

Although the theme park has been a major tourism destination in the United States, little research has been done in this industry. The growing economic significance and competition of the theme park industry ensure that the study of theme parks will emerge as a more popular research topic in the years to come. The authors review related articles and identify potential research topics in the theme park industry.

Age Structure Of Trees In Thorn Creek Woods, Jon Mendelson

Faculty Research and Creative Activity

Diameter distributions and age-size regressions are presented for 11 tree species from Thorn Creek Woods, Will County, Illinois. Diameter distributions showed a good fit to the negative power model of survivorship. Nevertheless, 7 of the 11 species showed the 'gap-bulge" pattern, with fewer than expected numbers in intermediate size classes. Although age-size regressions were generally significant, the scatter diagrams for most species showed clustering into two age groups undetected by regression analysis. The juxtaposition of these results suggests the presence of two cohorts on the site; one of post-settlement origin (after 1835), the other emerging after the decline of agriculture …

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 …

Size Distribution And Scattering Phase Function Of Aerosol Particles Retrieved From Sky Brightness Measurements, Y. J. Kaufman, A. A. Gitelson, A. Karnieli, E. Ganor, R. S. Fraser, T. Nakajima, S. Mattoo, B. N. Holben

School of Natural Resources: Faculty Publications

Ground-based measurements of the solar transmission and sky radiance in a horizontal plane through the Sun are taken in several geographical regions and aerosol types: dust in a desert transition zone in Israel, sulfate particles in Eastern and Western Europe, tropical aerosol in Brazil, and mixed continental/maritime aerosol in California. Stratospheric aerosol was introduced after the eruption of Mount Pinatubo in June 1991. Therefore measurements taken before the eruption are used to analyze the properties of tropospheric aerosol; measurements from 1992 are also used to detect the particle size and concentration of stratospheric aerosol. The measurements are used to retrieve …

Sprinkler Irrigaton: A Voc Remediation Alternative, Roy F. Spalding, Mark E. Burbach, Mary Exner Spalding, Leyla Parra-Vicary, Dennis R. Alexander

School of Natural Resources: Faculty Publications

A sprinkler irrigation system was tested to assess its efficacy for volatilizing organic chemicals in pumped ground water. In field tests involving the analysis of more than 250 samples collected from beneath a spray irrigation system, removal rates of ethylene dibromide (EDB), 1,1,2-trichloroethylene (TCE), 1,1,1-trichloroethane (TCA), and carbon tetrachloride (CT) in samplers placed 0.5 m above the ground exceeded 95% in the vast majority of cases, and approached 100% for the more volatile chemicals. As predicted by Henry’s Law, CT, TCA, and TCE were significantly more volatile than EDB. Removal efficiencies of conventionally designed sprinkler irrigation systems were enhanced by …

Windbreaks For Livestock Operations, Vernon Quam, Ladon Johnson, Bruce Wight, James R. Brandle

School of Natural Resources: Faculty Publications

Windbreaks play an important role in the protection of livestock, particularly in young animals and in areas with cold northerly winds during the winter and early spring. Properly placed windbreaks can provide benefits to feedlots, livestock pastures, and calving areas. Reducing wind speed in winter lowers animal stress, improves animal health, and increases feeding efficiency. Livestock windbreaks provide significant amounts of wildlife habitat, protect the working environment in and around the livestock area, and screen noise and odors associated with livestock operations.

Specific needs of animals dictate that special attention be given to access, snow storage, and drainage when planning …

Impacts Of Biological Invasions On The Management And Recovery Of Rare Plants In Haleakala National Park, Maui, Hawaiian Islands, Lloyd Loope, Arthur Medeiros

United States National Park Service: Publications

Biological invasions assisted by humans are impoverishing biological diversity worldwide (MacDonald et al. 1989, Diamond 1989). Such invasions are particularly devestating to the biota of oceanic islands such as Hawaii (Williamson 1981, Brockie et al. 1988, Hawaii Department of Land and Natural Resources et al. 1991). Ecosystems of the Hawaiian Islands are much more vulnerable to biological invasions than are continental ecosystems, because the organisms in them have evolved in isolation from many of the forces that have shaped continental organisms, including foraging and trampling by herbivorous mammals, predation by ants and mammals, virulent diseases, and fires (Loope & Mueller-Dombois …

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 …

Predicting Modes Of Toxic Action From Chemical Structure: An Overview, Steven P. Bradbury

Steven P. Bradbury

In the field of environmental toxicology, and especially aquatic toxicology, quantitative structure activity relationships (QSARs) have developed as scientifically-credible tools for predicting the toxicity of chemicals when little or no empirical data are available. A basic and fundamental understanding of toxicological principles has been considered crucial to the continued acceptance and application of these techniques as biologically relevant. As a consequence, there has been an evolution of QSAR development and application from that of a chemical-class perspective to one that is more consistent with assumptions regarding modes of toxic action. The assessment of a compound’s likely mode of toxic action …

Field Identification Of Birdseye In Sugar Maple (Acer Saccharum Marsh.), Douglas D. Stokke, Don C. Bragg

Douglas D. Stokke

Birdseye grain distortions in sugar maple must be identified to capture the full value of a timber sale throughout the economic range of birdseye's occurrence. Even when relatively common, birdseye veneer typically makes up less than 1 percent of the harvested volume, but may account for one-half of the value of the sale. With prices recently reaching $50,000 per Mbf for prime logs, omission of birdseye (when present) from cruise data could cause significant economic loss for the forest landowner. But figured wood can sometimes be detected in standing timber (Pillow 1955). Field identification of birdseye sugar maple is critical …

Predicting The Past, Recounting The Future: Human Ecology And A Prehistory Of Consciousness, Paul Faulstich

Pitzer Faculty Publications and Research

This paper is concerned with the organic derivation and primary meaning of Pleistocene finger flutings; I propose that in order to gain insight into the significance of the flutings, we must attempt an understanding of the physical and mental contexts in which they emerged. I suggest that finger flutings provided a cultural record in the Pleistocene which documented thought and action, and made it ready for reflection. Through the process of finger fluting, the human 'self' was objected and reality was modified in the experience of self-consciuosness. I argue that finger flutings, like language, were employed to discover and convey …

Identification And Assessment Of Wildlife Damage: An Overview, Richard A. Dolbeer, Nicholas R. Holler, Donald W. Hawthorne

Prevention and Control of Wildlife Damage Handbook

Wildlife management is often thought of in terms of protecting, enhancing, and nurturing wildlife populations and the habitat needed for their wellbeing. However, many species at one time or another require management actions to reduce conflicts with people or with other wildlife species. Examples include an airport manager modifying habitats to reduce gull activity near runways, a forester poisoning pocket gophers to increase tree seedling survival in a reforestation project, or a biologist trapping an abundant predator or competing species to enhance survival of an endangered species.

Wildlife damage control is an increasingly important part of the wildlife management profession …

Armadillo (Dasypus Novemcinctus), Donald W. Hawthorne

Prevention and Control of Wildlife Damage Handbook

The armadillo (Dasypus novemcinctus) is a rather interesting and unusual animal that has a protective armor of “horny” material on its head, body, and tail. The armadillo ranges from south Texas to the southeastern tip of New Mexico, through Oklahoma, the southeastern corner of Kansas and the southwestern corner of Missouri, most of Arkansas, and southwestern Mississippi. The armadillo prefers dense, shady cover such as brush, woodlands, forests, and areas adjacent to creeks and rivers. More than 90% of the armadillo’s diet is made up of insects and their larvae. The armadillo is active primarily from twilight through …

River Otters (Lutra Canadensis), Edward P. Hill

Prevention and Control of Wildlife Damage Handbook

River otters (Lutra canadensis) are best known for their continuous and playful behavior, their aesthetic value, and the value of their durable, high-quality fur. River otters occur throughout North America except the arctic slopes, the arid portions of the Southwest, and the intensive agricultural and industrialized areas of the midwestern United States. The diet of the river otter throughout its range is primarily fish. The reproductive biology of river otters and all other weasels is complex because of a characteristic known as delayed implantation. The presence of river otter(s) around or in a fish hatchery, aquaculture, or fish …
