Recycling Surplus Oil Funds And The Economies Of Some Non-Oil Producing Developing Countries, Patrick E. Archibong

Economic and Financial Review

The main objective of the paper is to examine, in general, the phenomenon of recycling against the background of enduring and fundamental disequilibria in the payments balances of the economies of non-oil producing developing countries. The technique used is, essentially, casual empiricism. In part I of the paper a brief attempt is made, using elementary micro-economic analysis, to illustrate conditions for the emergence of the surplus oil funds. Part 1 examines the mechanics and_ channels of recycling while Part 111 reflects on the attendant external debt burden of some non-oil producing developing countries. Part IV dwells on the limited effectiveness …

Influence Of Las Vegas Wash Density Current On Nutrient Availability And Phytoplankton Growth In Lake Mead, John R. Baker, Larry J. Paulson

Publications (WR)

Density currents are commonly formed in reservoirs because of temperature or salinity induced density differences between inflowing and receiving waters. Anderson and Pritchard (1951) were among the first to demonstrate this in their investigations of density currents in Lake Mead. They found that the Colorado River formed an underflow in Lake Mead during the winter, an overflow in the spring and an interflow in the summer and fall. Wunderlich and Elder (1973) have since described the hydromechanics of these types of flow patterns, and density currents have been reported for several other large reservoirs (Carmack et al. 1979, Johnson and …

Nutrient Interactions Among Reservoirs On The Colorado River, Larry J. Paulson, John R. Baker

Publications (WR)

Interactions among physical, chemical and biological processes in reservoirs can significantly alter the characteristics of the discharge (Neel 1963, Wright 1967, Hannan 1979) that, in turn, can influence the ecology of the river downstream .(Ward and Stanford 1979). Investigations of the Colorado River, system reveal that reservoir-induced changes in the river can also affect downstream reservoirs. The formation of Lake Powell, in 1963 was accompanied by reductions in suspended sediment and nutrient loading and changes in the seasonal temperature and discharge cycles of the Colorado River. In this paper, we evaluate how these changes have influenced the nutrient and trophic …

Whale Meat In The Japanese Diet, Robert L. Brownell Jr., Hideo Omura

United States Department of Commerce: Staff Publications

Junghans (Letters, 4 Apr., p. 6) points out several errors in Beary’s letter (14 December 1979, p. 1260) regarding the high concentrations of mercury in whale meat eaten by the Japanese. We would like to call attention to some additional errors in Beary’s letter.

The Future Of Coastal Zone Management: The 1980 Amendments, Kenneth J. Buckland

Marine Affairs Theses and Major Papers

The Federal Coastal Zone Management Act of 1972 (P.L.98-583) is currently being questioned on its validity, purpose, funding, wording, and accomplishments in carrying out national policies for the benefit of the U.S. coastal zones. All the legislation promulgated for management of coastal resources, the agencies involved in coastal zone management, and the groups participating in these actions have been challenged in recent months and have subsequently been evolving in their functions. What remedies are available and how they could be realized through the present federal laws and organizational structure are areas which must be discussed now if we are to …

State - Federal Relations In The Siting Of Nuclear Power Plants: Towards Greater State Authority, Walter A. Cooper

Marine Affairs Theses and Major Papers

The accident at the Three Mile Island (TMI), Pennsylvania nuclear powered electrical generating plant on March 28, 1979 has promoted a great deal of concern and interest in the future of nuclear power in the United States. Such concern is manifested by the unofficial moratorium imposed by the Nuclear Regulatory Commission (NRC) on the granting of new permits for the construction and operation of nuclear plants until the problems presented by the accident at TMI have been addressed. The NRC felt that the accident, at the very least, warranted consideration of a formal moratorium on plant licensing. Although a formal …

Chlorophyll Fluorescence Probe Of Ultraviolet-B Photoinhibition Of Primary Photoreactions In Intact Leaves, Robert S. Nowak

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Damage to primary photosynthetic reactions caused by environmental stress can be assessed by measurement of chlorophyll fluorescence induction in intact leaves. This approach was applied in studies of ultraviolet-B photoinhibition of photosynthesis in Pisum sativum L. and Rumex patientia L. leaves. At ultraviolet-B dose rates insufficient to cause inhibition of net photosynthesis, changes in the magnitude of fluorescence transients did occur, which suggested direct effects on chloroplast pigments in Pisum and inhibition of photosynthetic electron transport between the photosystems in both species. Leaves of these two species subjected to a much higher dose rate had a significant reduction of net …

Relationship Between Rainfall And Storm Runoff For Selected Arizona Watersheds, Robert James Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationship between rainfall and runoff was examined for twelve selected Arizona watersheds. Expedient runoff volume model coefficients and runoff curve number model parameters were examined using standardized structure, with modifications to adjust the model for small initial abstractions and large watershed storage capacity.

Forest-land management practices were examined for their effects on curve number coefficients. The effects of rainfall characteristics were also evaluated with respect to changes they induce in curve number populations.

Evaluations included a runoff fraction, a simple multiplier of storm volume to produce runoff volume. The accuracy of this model is promising for more permeable watersheds.

Resource Partitioning In Breeding Populations Of Marsh Hawks And Short-Eared Owls, Susan C. Linner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the 1979 breeding season four pairs of northern harriers, or marsh hawks (Circus cyaneus) and four pairs of short-eared owls (Asio flammeus) were studied in Cache Valley, Utah. The study was concerned solely with diurnal resource utilization, and did not examine the owls' nocturnal activities. The home range of each harrier pair overlapped substantially with that of an owl pair. Percent habitat overlap for hawk-owl pairs varied from 39 percent to 72 percent. Observations were made to determine if differences existed in their utilization of habitat and food resources, or in their daily and seasonal …

Effects Of Host Plant Patch Size And Surrounding Plant Type On Insect Population Dynamics, Lynn A. Maguire

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of the present study was to investigate how plant spatial patterns and insect behavior interact to influence the population dynamics of insects using the plants. The study included three phases: l) field experiments using collards (Brassica oleracea) and the crucifer insect fauna; 2) simulation models representing the population dynamics of an insect herbivore as functions of insect dispersal behavior and host plant patch size; and 3) model-field syntheses integrating model predictions and field variability estimates to choose an appropriate spatial scale for future field experiments or applications.

In field experiments on surrounding plant type, collards were …

Production Of Mountain Whitefish (Prosopium Williamsoni) In Altered And Unaltered Reaches Of Two Intermountain Streams In Their Alluvial Flood Plains, Michael J. Ottenbacher

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Estimates of production and related parameters (growth rate, density, standing crop) were made for populations of mountain whitefish in altered and "unaltered" areas of the Blacksmith Fork and Logan River, Utah from spring 1975 through summer 1976. Capture records of marked whitefish were also analyzed to describe fish movement and check on assumptions implicit in the population estimator.

Mean weights and instantaneous growth rates of whitefish were similar at all sites for comparable size/age groups. Among sites, differences in production per sampling interval and annual production were due mainly to differences in standing crop and/or age structure.

Estimates of mountain …

Allocation Of Reproductive Effort To The Male And Female Strategies In Wind-Pollinated Plants, Cliff A. Lemen

School of Natural Resources: Faculty Publications

Amaranthus and several other wind-pollinated species of plants are used to test some of the theoretical models of relative reproductive effort towards the male and female sexes. Consistent with these models, in self-compatible, monoecious Amaranthus, Chenopodium, Digitaria, Setaria, and Lepidium, female effort represented over 90% of the total reproductive effort. Also consistent with predictions, Lolium, a self-incompatible wind-pollinated species, was found to have about equal male and female effort. A method is described here that should prove useful in quantifying male and female effort in both wind and insect-pollinated species of plants.

Intrapopulational Morphological Variation As A Predictor Of Feedlng Behavior In Deermice, Richard A. Smartt, Cliff A. Lemen

School of Natural Resources: Faculty Publications

Within populations of animals that have determinate growth, all fully grown adults, even of one sex, are not identical. Both genetic and environmental factors are responsible for this variation. In recent years the importance of this variation has received much attention (Mayr 1963; Van Valen 1965; Fretwell 1969; Soule and Stewart 1970; Rothstein 1973). The important question asked has been, What effect does this morphological variation have on niche width and the ecology of a population? Implicit in many of these works is the concept that differences in the morphologies of population members can result in differences in their niches. …

Relationship Between Relative Brain Size And Climbing Ability In Peromyscus, Cliff A. Lemen

School of Natural Resources: Faculty Publications

Eisenberg and Wilson (Evolution, 32:740-751, 1978) have documented an interesting relationship between the relative brain size of bats and the complexity of the habitat in which they forage. They found that bats that fly and forage through foliage have larger brains relative to their body size than those that forage in open air. Their explanation was that bats in the complex habitat must process more complex sonic information to navigate through the foliage. In order to do this a larger brain is required.

The Peromyscus of North America may offer a similar paradigm as far as habitat complexity …

Simultaneous Transport Of Water And 3hoh In Water, H. D. Scott

Arkansas Water Resources Center Technical Reports

Dispersion of ³HOH was studied at flow velocities less than 14 cm/day in a Captina silt loam using the half-cell technique. Two directions of transport were studied: movement of ³HOH in the same direction as water, and movement of ³HOH in the opposite direction to that of water. Results indicated that the dispersion coefficients were velocity dependent for equilibration times ranging to 21 hours. As the average pore flow velocity increased, the length of time needed for the dispersion coefficients to become independent of the flow velocity increased. When considering transport of ³HOH in the same …

Ward V. Coleman, Cert. Granted (Sub Nom. United States V. Ward): A Fifth Amendment Problem In The Enforcement Of The Federal Water Pollution Control Act, Mark Cohen

Marine Affairs Theses and Major Papers

On March 23, 1975 oil leaked out of an oil retention pit at a drilling site owned by L.O. Ward. Ward was an Oklahoma wildcatter and the owner and operator of L.O. Ward Oil and Gas Operations. The spilled oil ran down a gully and into Boggie Creek. Boggie Creek is a tributary of the navigable Arkansas River. The discharge of oil from Ward's property therefore amounted to the discharge of a harmful quantity of oil within the meaning of Section 1321 (b)(3) of the Federal Water Pollution Control Act and also a harmful quantity within the meaning of regulations …

An Avoidance Response Bioassay For Aquatic Pollutants, Jeffrey A. Black, Wesley J. Birge

KWRRI Research Reports

Avoidance response bioassays were conducted with eight aquatic contaminants, including cadmium, copper, mercury, zinc, chloroform, dioctyl phthalate (DOP), trisodium nitrilotriacetic acid (NTA), and phenol. Tests were performed in a dual-channel fluviarium system, and the toxicant injection procedure used provided good regulation of exposure concentrations. Juvenile stages of largemouth bass (Micropterus salmoides), bluegill sunfish (Lepomis macrochirus), and rainbow trout (Salmo gairdneri), and tadpoles of the American toad (Bufo americanus) proved to be suitable animals for evaluating avoidance or attraction responses. The trout was the most sensitive species tested.

Avoidance was significant in tests …

Macrobenthic Communities Of An Industrialized Seaport Ecosystem: The Southern Branch Of The Elizabeth River, Virginia, Steven D. Hawthorne

Biological Sciences Theses & Dissertations

Macrobenthic invertebrates of an industrialized seaport ecosystem were studied seasonally from October, 1977 through July, 1978. Five stations were selected along the Southern Branch of the Elizabeth River, Virginia. The stations ranged from an area of heavy industrialization to a non-urbanized environment. At each station, bottom water was measured for salinity, temperature, dissolved oxygen, and pH. Within each sampling area, macrobenthic infauna! invertebrates were collected from in and out of channel sites along with sediment samples for various types of physicochemical analysis.

Community structure was spatially homogeneous at station sites and throughout the stations along the River. Slightly acidic pH …

Isolation And Enumeration Of Enteric Viruses From Primary Wastewater Sludge, Michael Wayne Nath

Biological Sciences Theses & Dissertations

The presence of large numbers of enteric viruses in wastewaters has resulted in concern regarding their significance and consequences for humans. Assessments of relative significance or consequences may most accurately be made following precise measurements of the range of virus types and amounts in wastewaters and sludges and after epidemiological considerations. In this study, results are presented pertaining to enteric virus isolation, concentration, and enumeration from primary wastewater sludges.

As an integral part of a comparison of isolation procedures, several anionic surfactants were examined for extraction of enteric viruses from primary wastewater sludges. Plaquing efficiencies for poliovirus type 2 and …

Exclusion Of Gulls From Reservoirs In Orange County, California, William Amling

Vertebrate Pest Conference Proceedings: 9th (1980)

Measures to exclude gulls from two coastal domestic water supply reservoirs in Orange County have included the use of shotguns, exploding shell cartridges and carbide cannons. Alternative methods were explored which hopefully would prove more effective and less costly than the harassment techniques being employed. The installation of a network of spaced wire over the reservoir water surface has successfully excluded gulls from these bodies of water.

Mountain Beaver Problems In The Forests Of California, Oregon And Washington, John E. Borrecco, Robert J. Anderson

Vertebrate Pest Conference Proceedings: 9th (1980)

Mountain beavers (Aplodontia rufa) cause considerable damage to forest trees in the Pacific Northwest. Feeding injuries result in mortality, growth losses, deformity of trees, and understocked plantations. Losses are most severe in new plantations with significant damage problems also occurring in sapling stands. Trapping, and placing physical barriers around individual trees, are the most common methods of control. Both methods are costly but effective in reducing damage.

The Situation Of Grain-Eating Birds In Somalia, Richard L. Bruggers

Vertebrate Pest Conference Proceedings: 9th (1980)

Research into the biology and control of pest birds in Somalia has continued intermittently since 1971 under UNDP funding of four projects. Data have been gathered on the identification, distribution, and status of the principal pest species to agriculture. These species include the Red-billed Quelea (Quelea quelea), of which northern and southern races occur, and several other ploceid weavers (Ploceus spp.) which may damage cereal crops. The movements, food habits, and corresponding impact of these species on agriculture in Somalia are discussed in detail. As a result of the information obtained during these years of research, emphasis has recently shifted …

Lithium Chloride Bait Aversion Did Not Influence Prey Killing By Coyotes, Richard J. Burns, Guy E. Connolly

Vertebrate Pest Conference Proceedings: 9th (1980)

Conditioned food or flavor aversion has been proposed as a method to stop coyote predation on sheep. The method entails treating sheep carcasses or meat baits with an emetic, lithium chloride (LiCl), and scattering them on sheep ranges. Theoretically, coyotes eat the baits, become ill, and subsequently desist from killing and eating sheep because they associate sheep flavor with sickness. In recent studies, coyotes have not formed prey aversions. Coyotes avoided baits because of LiCl flavor rather than prey flavor and prey killing aversions were not found. We conducted a study designed to find the best LiCl-prey flesh concentration to …

Armadillos: Problems And Control, Patricia A. Chamberlain

Vertebrate Pest Conference Proceedings: 9th (1980)

The nine-banded armadillo (Dasypus novemcinctus) has been successful in extending its range throughout the southeastern states. It occupies such a diverse range of habitats that its effects on its surroundings depend largely on where it is located. It offers benefits from its burrowing and eating patterns by creating dens for furbearers and destroying large quantities of injurious insects and their larva. Those same activities in urban and suburban areas are now being recognized as a source of considerable nuisance and moderate damage. Damage is most severe from July through early November. They have been recognized in connection with several diseases …

Changes In A Feral Pig Population After Poisoning, James Hone, Henry Pedersen

Vertebrate Pest Conference Proceedings: 9th (1980)

The changes in a feral pig population associated with 1080 poisoning were examined. There was a 58.1% reduction in population size after poisoning with no age-specific effect. The population size increased over 11.5 months after poisoning at an observed instantaneous rate of increase per year of 0.57. The results are discussed relative to feral pig control.
