The Impact Of Mining And Mining Exploration On Range Resources And Pastoral Pursuits In The Pilbara, Gascoyne, Murchison And Goldfields Regions Of Western Australia, H J. Pringle, G A. Carter, J L. James, R E Y O'Connor

Resource management technical reports

Mining activity occurs very widely over relatively small areas of the rangelands. However, it is an intense landuse which can create significant offsite effects. Mining activity is most common around metamorphic 'greenstone' belts and broad drainages. Pastoralists reported both benefits and adverse affects as a consequence of mining activity. The main grievances related to unnecessary and excessive disturbance of pastoral land and the failure of operators to inform the pastoralist of their intentions.

The Australian Lupin Collection - Passport Data For Wild And Semi-Domesticated Accessions Introduced Into Australia To 1990, J. C. Clements, W. A. Cowling

Grain and other field crops published reports

This report contains passport (including collection site) data and Commonwealth Plant Introduction (CPI) numbers for all wild and semi-domesticated Lupinus accessions introduced into Australia to 1990 (a total of 1071 accessions with CPI numbers between 10650 and 122692). Scientists or plant breeders with an interest in the characteristics of wild lupins from certain natural environments, such as high soil pH or low rainfall, will find this information invaluable when they select accessions for their experiments. The majority of the accessions were introduced by Western Australian scientists following collecting missions in the Mediterranean region, and the remainder were donated from institutions …

The Effects Of Two Polycyclic Aromatic Hydrocarbons Benzo[A]Pyrene And Naphthalene On Reproductive Success Embryological Development Larval Physiology And Mortality Of The Mud Crab Rhithropanopeus Harisii (Gould), Gregory V. White

OES Theses and Dissertations

Polycyclic aromatic hydrocarbons (PAHs) such as naphthalene (Nap) and benzo[a]pyrene (B[a]P) are common in the water column and sediments of estuarine and coastal areas. The mud crab Rhithropanopeus harrisii was exposed to varying concentrations of Nap or B[a]P to determine the effects on reproductive success, embryological development, larval physiology and mortality. Nap and B[a]P decreased hatching success and prolonged embryological development. Both pollutants produced high abnormality frequencies for egg exposed larvae. Molt frequency and respiratory rates of larvae from non-exposed eggs were more chronically affected by these pollutants than were egg exposed larvae. The EC₅₀ concentrations were determined for …

Hydrogeology And Water Budget Analysis Of Two Interdunal Ponds Nags Head Woods Ecological Preserve, Dare County, North Carolina, Richard A. Hisert

OES Theses and Dissertations

Ground-water-fed interdunal ponds in Nags Head Woods Ecological Preserve lose as much as 7600 m³ yr^-1 of water through evaporation. This withdrawal of groundwater is sufficient to significantly alter flow patterns through the surficial aquifer on Bodie Island, N.C. Statistical analyses of evaporation estimates derived by various methods indicate a weak correlation, (r²=0.4-0.5) between pan evaporation data from Aurora, N.C. and pond evaporation at Nags Head Woods calculated by water budget analyses.

Results of stratigraphic and pedologic analyses in and around the ponds indicate that the ponds formed after development of multiple generations of dunes. This …

Hawaii's Hottest Issue: Update On Geothermal Development, Paul Faulstich

Pitzer Faculty Publications and Research

Walking through Hawai'i's Wao Kele O Puna rainforest, you can hear the coarse volcanic soil crunch underfoot. A surrealistic calm lingers in the thick air while songbirds call out from the understory. Yet this is a forest under siege.

Geothermal developers want to tap the volcanic heat beneath the Wao Kele O Puna forest and use it to make electricity and profits.

Malaysian Deforestation Proceeds Apace, Paul Faulstich

Pitzer Faculty Publications and Research

A hunger fast, dubbed Fast Action, was staged in front of the Japanese Consulate General in Honolulu on July 20 to protest the destruction of the most ancient and biologically diverse ecosystem on Earth. Organized by Hawai'i Earth First! and the O'ahu Rainforest Action Group, Fast Action was designed to alert people to the destruction of tropical rainforests in Sarawak, Malaysia. Protesters demanded on immediate moratorium on the cutting of rainforests in,which the Penan and other-native peoples live.

Future Policy For Charter Fishing Operations In Western Australia., P. Millington

Fisheries Management Papers

About 40 boats in Western Australia gain some of their income from taking recreational fishing parties out on charter. Half of these charter boats are also licensed commercial fishing boats. There are few Fisheries Department controls over charter boat fishing at present. However, with increasing tourism and leisure time, there are sound reasons for the Minister for fisheries to tighten up the controls over charter boat fishing to prevent over-exploitation in some areas or on particular stocks.

Alternative Usages Of Wetlands Other Than Conventional Farming In Iowa, Kansas, Missouri, And Nebraska, Ellen Leventhal, Hubert H. Humphrey

United States Environmental Protection Agency: Publications

Conversion of wetlands in Iowa, Kansas, Missouri, and Nebraska into agricultural dry lands in the past several decades has occurred as a means to obtain profit from what landowners would otherwise consider unprofitable land. This activity has resulted in substantial losses of wetlands valued for their unique ability to mitigate flood and storm damage, control erosion, discharge and recharge groundwater, improve water quality, and support a wide diversity of fish, wildlife, and vegetation.

Utilizing fish, wildlife, and vegetation from wetlands for profit is a way for wetland owners to recognize the value their wetlands add to their property. Landowners then …

Superfund Record Of Decision: Monticello Mill Tailings (Doe), Ut First Remedial Action, U.S. Environmental Protection Agency, Office Of Emergency And Remedial Response

All U.S. Government Documents (Utah Regional Depository)

The 300-acre Monticello Mill Tailings site is comprised of a 7S-acre inactive uranium and vanadium milling operation and affected peripheral properties in Monticello, San Juan County, Utah. Surrounding land use is rural residential and agricultural. The site overlies a shallow alluvial aquifer, and part of the site lies within the floodplain of Montezuma Creek. Approximately IS-acres of wetlands adjacent to Montezuma Creek also have been contaminated by tailings. In 1940, the site was operated as a vanadium ore-buying station. Milling of ore began in 1942, and a vanadium/uranium sludge product was produced onsite from 1943 to 1944. Onsite uranium milling …

Factors Affecting Wood Fuel Consumption And Environmental Impacts In Warren County, Kentucky, Barry Vann

Masters Theses & Specialist Projects

The purpose of this research is to identify factors that contribute to wood fuel consumption as a space heating source and estimate a county-wide proportion for wood fuel consuming households. In addition, environmental problems associated with deforestation such as erosion and loss of wildlife habitat are delineated; moreover, air pollution resulting from wood fuel emissions are discussed.

An exhaustive literature review provided the basis for the study. Data on Warren County wood fuel consumption patterns were derived from a mail survey. Proportion estimates were tested by using a classical two-tail test of hypothesis. Subsequently, factors were identified and used in …

Metal Speciation And Immobilization Reactions Affecting The True Efficiency Of Artificial Wetlands To Treat Acid Mine Drainage, Anastasios D. Karathanasis, Y. L. Thompson

KWRRI Research Reports

The ability of constructed wetlands to lower total metal concentrations and organically complex metals in acid mine drainage (AMD) was investigated under greenhouse and field conditions. In the greenhouse study, Typha plants grown in six different substrates received simulated acid mine drainage of low metal load for five months. Most effluents, especially those from ground flows, showed significant decreases in acidity and metal concentrations. The pine needle and hay substrates most effectively reduced acidity and total Al levels. Effluents from these substrates contained 80% less total Al than respective influents. Organically complexed Al levels were independent of matrix and varied …

Bulletin No 4191 - Inputs For Beefin, D. J. Barker, P J. May, R. G. Grieve

Bulletins 4000 -

BEEFIN is a computer model (Barker et at. 1986) that calculates profit maximizing diets for finishing cattle to a specified carcass weight and fat thickness. It predicts cattle growth, feed conversion ratio, final liveweight, number of days on feed and amount of available feedstuffs to finish the cattle to specification.

BEEFIN calculates an enterprise profit and loss budget and performs a sensitivity analysis on cattle and feed price changes. A sensitivity analysis of returns to assets, variable costs and per tonne of feed fed is also calculated.

A Logic For Natural Language, William C. Purdy

Electrical Engineering and Computer Science - Technical Reports

This paper describes a language called £N whose structure mirrors that of natural language. £N is characterized by absence of variables and individual constants. Singular predicates assume the role of both individual constants and free variables. The role of bound variables is played by predicate functors called "selection operators." Like natural languages, £N is implicitly many-sorted. £N does not have an identity relation. Its expressive power lies between the predicate calculus without identity and the predicate calculus with identity. The loss in expressiveness relative to the predicate calculus with identity however is not significant. Deduction in £N is intended to …

Bulletin No 4174 - Tree Planting On Farms In High Rainfall Areas, Ken Angell

Bulletins 4000 -

Many of the techniques described in this Bulletin are applicable to broadacre farms. However, they are specifically directed to small rural properties in the high rainfall areas.

Trees can usually serve more than one purpose on small rural properties. They can be used as ornamentals, to provide shelter and shade, for erosion control, as a wildlife habitat, or for waterlogging and salinity control.

The Fokker-Planck And Related Equations In Theoretical Population Dynamics, George Derise

Mathematics & Statistics Theses & Dissertations

The population growth of a single species is modeled by a differential equation with initial condition(s) so that the number of organisms in the population is derived using some mechanism of growth, i.e. a growth rate function. However, such deterministic models are often highly unrealistic in population dynamics because population growth is basically a random event. There are a large number of chance factors influencing growth that might not be taken into account by deterministic models. The effect of other species (for example, in the chance meeting of a predator), population fluctuations due to weather changes that would alter food …

Fisheries Research Report No. 89 - Relationships Among Partial And Whole Lengths And Weights For Western Australian Pink Snapper Chrysophrys Auratus (Sparidae), M. J. Moran, C. Burton

Fisheries Research Reports

Pink snapper, Chrysophrysauratus (Sparidae) is one of the major commercial and recreational fish in Western Australian inshore waters. This report presents a number of equations and conversion factors for management and scientific study of the species. Equations to calculate total lengths from partial lengths will facilitate enforcement of minimum legal lengths when snapper are landed in a "head-off" condition. For fisheries science purposes, there are equations to convert among total length, standard length and length to caudal fork; and to convert lengths and weights of processed fish to whole lengths and weights. Length-weight relationships are presented and compared with those …

Taxonomic Reasoning And Lexical Semantics, William C. Purdy

Electrical Engineering and Computer Science - Technical Reports

Taxonomic reasoning is used in many applications, including many-sorted logic, knowledge bases, document retrieval, and natural language processing. These various applications have been dealt with independently. Because they have so much in common, a general approach to taxonomic reasoning would seem to be justified. This paper presents a theory of lexical semantics as an example of such a general approach. The theory defines a representation and an algebra for that representation. The operations of the algebra are inherently parallel, making them well matched to the capabilities of modern computer systems.

Coke Oven Emissions: A Case Study Of Technology-Based Regulation, John D. Graham, David R. Holtgrave
