Ecological Economics: Reintegrating The Study Of Humans And Nature, Robert Costanza
Ecological Economics: Reintegrating The Study Of Humans And Nature, Robert Costanza
Institute for Sustainable Solutions Publications and Presentations
Ecological economics is a transdisciplinary effort to link the natural and social sciences broadly, and especially ecology and economics. The goal is to develop a deeper understanding of the complex linkages between ecological and economic systems, and to use that understanding to develop effective policies that will lead to a world that is ecologically sustainable, has a fair distribution of resources (both among groups and generations of humans and between humans and other species), and efficiently allocates scarce resources including natural capital. This will require new approaches that are comprehensive, adaptive, integrative, multi-scale, and pluralistic, and that acknowledge the huge …
Reductive Dehalogenation Of Chlorinated Aromatic And Aliphatic Hydrocarbons Under Anaerobic Conditions, Monica Turner Togna
Reductive Dehalogenation Of Chlorinated Aromatic And Aliphatic Hydrocarbons Under Anaerobic Conditions, Monica Turner Togna
Dissertations
The process of reductive dehalogenation involves the removal of a halogen substituent from a molecule with the concurrent addition of electrons to the molecule, resulting in a more reduced and often less toxic product. Anaerobic bacteria have the potential to utilize hazardous chlorinated aromatic and aliphatic hydrocarbons as electron acceptors in metabolic reductive dehalogenation processes.
In experiments performed with chlorinated aromatic compounds a highly enriched anaerobic culture stoichiometrically converted 2,4,6-trichlorophenol (2,4,6-TCP) to 4-monochlorophenol. Dehalogenation occurred only in alkaline media (pH 8-9) at concentrations of 2,4,6-TCP up to 1 mM. Data indicated that the dehalogenating organism did not fit into any …
Scaling Up Of Water-Based Organic Reactions, Chen Gu
Scaling Up Of Water-Based Organic Reactions, Chen Gu
Dissertations
Three water-based organic reactions, Diels-Alder, epoxidation of olefins, and free-radical bromination have been investigated as an approach to pollution prevention. The first two systems were scaled-up by at least a factor of 20. These reactions are of special interest to the pharmaceutical and speciality chemical industries. The photo-induced free-radical bromination of alkanes with bromine in water was studied in a two-phase system. Experimental results show that all reactions have advantages resulting from being conducted in water, such as reaction rate acceleration, reaction selectivity increase, and the absorption of water-soluble gas byproduct by solvent water.
The effects of stirring rates, temperature, …
Effect Of Vitamin Supplementation On Biodegradation Of Aliphatic Hydrocarbons And Diesel Fuel, Susmita Guptapal
Effect Of Vitamin Supplementation On Biodegradation Of Aliphatic Hydrocarbons And Diesel Fuel, Susmita Guptapal
Dissertations
Bioremediation of hazardous wastes is proven to be environmentally benign and most cost effective technology when proper conditions are provided. However, commercialization of this method still requires comprehensive research to enhance the degradation rate to make the technology more acceptable for implementation. In this research a unique approach to increase the rate of biodegradation by vitamins supplementation was studied.
Five vitamins, niacin, biotin, folic acid, thiamin and pantothenic acid were selected for the present study. Different short chain (C8 and C9), and long chain (C16 and C17) aliphatic hydrocarbons and diesel fuel (a mixture …
Factors That Influence Changes In Temporal And Spatial Accumulation Of Debris On An Estuarine Shoreline, Cliftwood Beach, New Jersey, Usa, Laura Pace
Theses
A field investigation was conducted on an estuarine shoreline in Raritan Bay, New Jersey to identify the temporal and spatial distribution changes in accumulation of marine debris, and the factors that influence these changes. Methodology consists of 12-monthly collections of debris and profile data, and collection of local climatological and tide data. Debris was classified by type, length, weight, fragmentation, and probable function and weathering noted for each collected item. Wind roses were constructed to determine dominant wind speed and direction and wind characteristics for time intervals between field sampling.
Plastics are the primary component of debris; glass and styrofoam …
Age Classification Of Laughing Gulls Based On Summer Plumage, Jerrold L. Belant, Richard A. Dolbeer
Age Classification Of Laughing Gulls Based On Summer Plumage, Jerrold L. Belant, Richard A. Dolbeer
United States Department of Agriculture Wildlife Services: Staff Publications
We described quantitatively 19 summer plumage characteristics and bill and foot pigmentation of 247 known-age Laughing Gulls (Larus atricilla) collected in New York during 1992-1994. There were no differences in characteristics measured for male and female Laughing Gulls. Ninety percent of 2-yr-old Laughing Gulls and 96% of ≥ 3-yr-old birds had full hoods. Fifty-seven percent of 2-yr-old Laughing Gulls possessed at least partial tail bands in contrast to 4% of 3-yr-old and 0% of ≥ 4-yr-old gulls. Thus 2-and ≥ 3-yr-old Laughing Gulls cannot be separated reliably by the presence or absence of a tail band. Pink pigmentation on the …

Promoting The Flow Of Investment Resources Into Nigeria's Petroleum Industry, M O. Ojo, C. M. Anyanwu
CBN Occasional Papers
The objective of the paper is to review the investment climate and policy incentives designed for the Nigerian oil industry with a view to evaluating how supportive they have been in terms of attracting investment funds into the sector. The industry has grown over the years to become the backbone of the economy. Given its strategic role, recent revelations of possible distress in the sector attributable to fast declining investment expenditure, deserves analysis and remedial actions. The investment needs of the industry are massive. A survey of the. sector shows that there is a large resource gap between its needs …

Fisheries Research Report No 108 - Aspects Of The Biology And Stock Assessment Of The Whitebait, Hyperlophus Vittatus,In South Western Australia, D. J. Gaughan, W. J. Fletcher, R J. Tregonning, J. Goh
Fisheries Research Reports
The biology, distribution and stock size of whitebait along the lower west coast of Western Australia were studied between 1991 and 1994. Age, growth and reproductive biology of whitebait were investigated using samples collected from the commercial fishery. The distribution of adult whitebait and their main spawning times were determined using data on eggs that were caught in plankton samples. Aspects of the population dynamics of whitebait were investigated by examining the relationships of historical catch data with fishing effort and some environmental parameters.
Whitebait are a small species with most growth occurring in the first year (K = I. …

Fisheries Research Report No 107 - Chemical Composition Of Yabbies (Cherax Albidus Clark 1936) From Western Australian Farm Dams, Kevin A. Francesconi, Noel M. Morrissy
Fisheries Research Reports
Proximate analyses, amino acid and fatty acid profiles, mineral composition and heavy metal and pesticide residues have been determined for tail muscle from Cherax albidus Clark 1936 (the yabby), sampled from Western Australian farm dams. The proximate analysis values for water, protein, ash, carbohydrate and energy content and the amino acid and fatty acid profiles of yabby tail muscle were similar to those reported for other decapods. Fat levels were low and, hence, cholesterol was very low in tail meat. Organochlorine pesticides were undetectable and heavy metal residues were well below maximum permitted concentrations for human consumption.

Seagrass In Tampa Bay: Historic Trends And Future Expectations, J.O. R. Johansson, T. Ries
Seagrass In Tampa Bay: Historic Trends And Future Expectations, J.O. R. Johansson, T. Ries
Reports
In this bay segment, seagrass cover has increased from near zero in 1984 to about 40 ha in 1996. The seagrass expansion apparently started in response to water quality improvements which occurred more than a decade ago and which in turn followed a large reduction in nitrogen loading form primarily domestic and industrial point-sources. Although this nutrient reduction occurred almost two decades ago it is most likely still contributes to the current seagrass expansion.
