Section I: Thermodynamic Properties Of Hydrocarbon Radicals, Peroxy Hydrocarbon And Peroxy Chlorohydrocarbon Molecules And Radicals Section Ii: Kinetics And Reaction Mechanisms For : (1) Chloroform Pyrolysis And Oxidation (2) Benzene And Toluene Oxidation Under Atmospheric Conditions, Tsan-Horng Lay

Dissertations

Alkyl radicals are important active intermediates in gas phase photochemistry and combustion reaction systems. With the exception of a limited number of the most elementary radicals, accurate thermodynamic properties of alkyl radicals are either not available or only rough estimations exist. An H atom Bond Increment approach is developed and a data base [sic] is derived, for accurately estimating thermodynamic properties (ΔH_f°₂₉₈, S°₂₉₈ and Cp(T)) for generic classes of hydrocarbon radical species.

Reactions of alkyl radicals with molecular oxygen are one of the major reaction paths for these radicals in atmospheric photochemistry, oxidation of hydrocarbon …

Quantitative Studies Of An Immobilized Cell Oxidative Bioreactor, Timothy Lance Borkowski

Theses

The purpose of this work was to determine a suitable method of utilizing dissolved oxygen in reservoir solution data to quantitatively measure the amount of oxygen and substrate consumed for an immobilized cell batch bioreactor in a recirculation configuration. Statistical analysis was performed on multiple phenol injections to determine the mathematical relationship between dissolved oxygen readout and the amount of phenol degraded.

Factors considered in the mathematical analysis include amount of substrate degraded, reaction time, recirculation flow rate, measured dissolved oxygen concentration and oxygen consumption, oxygen conversion per pass through the bioreactor during steady state, and vitality of the microorganisms. …

Catalytic Oxidation Of Trichloroethylene Over 5% [Alpha]-Fe2o3/[Gamma]-Alumina On A Honeycomb Monolith, Jeongho Han

Theses

This study addresses the ability of iron oxide to catalytically oxidize low concentrations of trichloroethylene (TCE) with air. The catalytic oxidation of trichloroethylene in a tubular reactor system was evaluated experimentally as a function of temperature and space velocity. A gas chromatograph with electron capture and flame ionization detectors was used for quantitative analysis of feed and product streams. X-ray diffraction measurement were used to qualitatively analyze the catalyst. The result indicate that over 99% conversion of 109 ppmv trichloroethylene in air is achieved at 1,490 v/v/hr and 450 °C, and at 21,768 v/v/hr, 550 °C. The major products from …

The Growth, Enrichment, And Dehalogenating Properties Of Pyrococcus Gbd And Desulfurococcus Sy, Siegfried Georg Mueller

Theses

Recent investigations of volcanic smoker chimneys along the Atlantic Rift has lead to the discovery of hyperthermophilic bacteria. In particular, Pyrococcus GBD and Desulfurococcus SY were studied, optimizing growth conditions. This was achieved using elemental sulfur amendments, artificial sea water, and dehydrated marine broth. The microbes were then acclimated to enriched cultures containing 2,4,6 trichlorophenol in 0.0126 mM, 0.063 mM, and 0.126 mM amendments. The amended cultures showed dehalogenating properties and were subjected to a data qualifying program. This program indicated that the dehalogenation was a function of microbial gowth. A mass balance experiment showed that both microbes were able …

Bioremediation Of 2-Chlorophenol In A Laboratory Soil Column, Timothy A. Coon

Theses

In-situ bioremediation offers the prospect of rendering organic contaminants harmless without having to remove them from the subsurface. It involves the modification of environmental factors to stimulate the biodegradation of chemicals in the subsurface by microorganisms. However, for the cost-effective use of in-situ bioremediation, it is necessary to develop accurate engineering models to quantify biodegradation.

In this thesis, the biodegradation of 2-chlorophenol in a laboratory soil column was examined in order to experimentally verify an engineering model. Experiments were performed to obtain the physical and biological parameters required by the model, and the steady-state 2-chlorophenol distribution in the column.

Abundance Of Gulls And Other Birds At Landfills In Northern Ohio, Jerrold L. Belant, Thomas W. Seamans, Steven W. Gabrey, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

We estimated the abundance of birds at three landfills in northern Ohio from May 1991-July 1992 recording 699,350 individuals of 42 species. Gulls (Larus spp.) comprised 94.5% of the birds recorded followed by European starlings (Sturnus vulgaris, 5.0%) and turkey vultures (Cathartes aura, 0.3%). Gulls were primarily of two species, ring-billed (L. delawarensis, 74.49%) and herring (L. argentatus, 25.50%). The mean number of gulls per observation during July-January was at least five times the mean number observed during other months. The combined monthly mean number of gulls at the three landfills peaked in August (>4000 birds), with gulls virtually …

Geomorphic And Pedogenic Evolution In Coastal Sediments, Central California, Lynn E. Moody, R. C. Graham

Natural Resources Management and Environmental Sciences

Studies of soil chronosequences on marine terraces facilitate the use of terraces for tectonic and paleoclimatic interpretation. However, many areas on the California coast have received substantial eolian deposits after pedogenesis began, so do not qualify as chronosequences. These areas are worthy of study because they are widespread coastal landscape features, and they enable us to interpret pedogenic and geomorphic processes in sandy regolith. The objective of this study was to use soil and deep regolith morphology and chemistry to interpret pedogenic and geomorphic evolution on a sequence of four marine terraces, San Luis Obispo County, California. The terraces are …

Nature Conservation In The Western Australian Wheatbelt, Max Abensperg-Traun

Journal of the Department of Agriculture, Western Australia, Series 4

Growing concern about the survival of flora and fauna in the Western Australian wheatbelt prompted CSIRO scientists to start a long-term study to moniter trends in populations. Max Abensperg-Traun and his colleagues reportt on their findings so far.

Land Use Patterns In Relation To Lake Water Quality In The Long Pond, South Basin Watershed, Problems In Environmental Science Course (Biology 493), Colby College, Colby College

Colby College Watershed Study: Long Pond, South (2007, 1995)

Long Pond, South Basin receives nutrient inputs from a variety of sources, including roads, construction projects, logging practices, and human waste from subsurface waste disposal systems. If any of these sources are near tributaries or the shoreline, the nutrients can be easily transported into the lake itself. The lake is also used recreationally for boating, fishing and swimming, and is utilized as a source of drinking water for seasonal shoreline residences. The watershed contains the Mt. Vernon and Belgrade transfer stations, and the dump has been capped at each of these stations.

Historically, Long Pond, South Basin has not suffered …

Making Horticulture Sustainable, Bob Paulin, Neil Clifton Lantzke, Ian Mcpharlin, Murray Hegney

Journal of the Department of Agriculture, Western Australia, Series 4

Sweet crunchy carrots, luscious strawberries at very reasonable prices, crisp green vegetables - these are just a few of the horticultural products that Western Australians take for granted and eat almost every day. But is their future availability guaranteed as population grows, suburbia spreads and environmental concern increases?

Kate McInnes reports on progress with the Avon Catchment Landcare Project.

Benchmarks For The Rangelands : Mapping And Assessing Country Types In The Outback, Hugh Pringle, Alan Payne

Journal of the Department of Agriculture, Western Australia, Series 4

Rangeland surveys map and describe the outback to help evaluate whether current land uses are appropriate and to highlighe areas with potential form other land uses.

The information can also be used to help minimise adverse environmental impacts, restore damaged areas and better use natural recourses in a sustainable fashion.

Hugh Pringle and Alan Payne outline the survey program which has been in progress for a number of years.

Storm : [Wind Erosion In The Great Southern], Dan Carter

Journal of the Department of Agriculture, Western Australia, Series 4

On Thursday 11 May 1995, a low pressure system with central barometric pressure of 990 hPa formed of south-western Australia. This depression directed gale force winds over the South-West Land Division for some seven hours.

Dan Carter reports on the widespread damage to soils and property, and management practices that would have reduced the problem.
