The main focus of this paper will be upon fisheries development in Mauritania and how it may contribute to alleviating malnutrition. The examination of Mauritania's fisheries policy, the significance of the political and economic context in which fishing policy was formulated, the effects that these different policies have on Mauritania's overall development …


An Evaluation Of Noaa's Role In Ocean Dumping Policy Implementation, Kenneth W. Barton Jan 1990

An Evaluation Of Noaa's Role In Ocean Dumping Policy Implementation, Kenneth W. Barton

Marine Affairs Theses and Major Papers

Dumping of wastes into the ocean has gone on for years especially in the New York Bight. The National Oceanic and Atmospheric Administration (NOAA) is mandated by Title II of the Ocean Dumping Act of 1972 to investigate the effects of ocean dumping on the marine environment. However, there is a perception within Congress, the public and other agencies that NOAA is not meeting it's responsibilities with regard to ocean dumping research. The effectiveness of NOAA's ocean dumping policies and programs and the difficulties in implementation experienced by the agency are evaluated by applying George Edwards' theory of policy implementation. …

On-Line Process Fiber Optic Refractometer For Measuring Edible Oil Hydrogenation, Charles F. Cole, Robert A. Sims, Alois (Al) J. Adams

Journal of the Arkansas Academy of Science

The process of edible oil partial hydrogenation has improved steadily over the past decades, but few on-line process instruments exist capable of measuring the extent of hydrogenation. This work describes the design of a prototype, on-line fiber optic refractometer for controlling and monitoring of oils. It uses an established correlation between the degree of hydrogenation of an edible oil and its refractive index (Rl). The refractometer cell uses a bare optical fiber in direct contact with processing oil. Equations are given describing the power transmission characteristics of an optical fiber as a function of its cladding Rl. Comparisons between calculated …

Hawaii's Rainforest Crunch: Land, People, And Geothermal Development, Paul Faulstich Jan 1990

Hawaii's Rainforest Crunch: Land, People, And Geothermal Development, Paul Faulstich

Pitzer Faculty Publications and Research

One hundred and forty-one people, led by Native Hawaiians, were arrested on 25 March 1990 as part of the largest demonstration yet against geothermal development in Hawaii. The gathering was intended to focus attention on Native Hawaiian rights and the ecological consequences of drilling geothermal wells in the near-pristine Wao Kele O Puna rain forest. The energy project, undertaken by True Geothermal Company and endorsed by Hawaii's governor and other imposing figures, has already invaded the largest intact tropical lowland rain forest in the United States.


Intermolecular Potential Of The Methane Dimer And Trimer, M. M. Szczesniak, G. Chalansinski, S. M. Cybulski, Steve Scheiner Jan 1990

Intermolecular Potential Of The Methane Dimer And Trimer, M. M. Szczesniak, G. Chalansinski, S. M. Cybulski, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

The Heitler–London (HL) exchange energy is responsible for the anisotropy of the pair potential in methane. The equilibrium dimer structure is that which minimizes steric repulsion between hydrogens belonging to opposite subsystems. Dispersion energy, which represents a dominating attractive contribution, displays an orientation dependence which is the mirror image of that for HL exchange. The three‐body correction to the pair potential is a superposition of HL and second‐order exchange nonadditivities combined with the Axilrod–Teller dispersion nonadditivity. A great deal of cancellation between these terms results in near additivity of methane interactions in the long and intermediate regions.


Environmental Assessment Seminoe-Kortes Transmission Line/Substation Consolidation Project, Carbon County, Wyoming, U.S. Department Of Energy Jan 1990

Environmental Assessment Seminoe-Kortes Transmission Line/Substation Consolidation Project, Carbon County, Wyoming, U.S. Department Of Energy

Environmental Assessments (WY)

The existing switchyards at Western Area Power Administration's (WESTERN) Seminoe and Kortes facilities, located approximately 40 miles northeast of Rawlins, Carbon County, Wyoming, were constructed in 1939 and 1951, respectively. The circuit breakers at these facilities are beyond or approaching their service life and need to be replaced. In addition, the switchyards have poor access for maintenance and replacement of equipment, and their locations create potential for oil spills into the North Platte River. WESTERN is proposing to consolidate the switchyard facilities into one new substation to provide easier access, restore proper levels of system reliability, and decrease the potential …

Fisheries Research Report No. 84 - The Marine Open Shelf Environment: Review Of Human Influences, D. A. Hancock Jan 1990

Fisheries Research Report No. 84 - The Marine Open Shelf Environment: Review Of Human Influences, D. A. Hancock

Fisheries Research Reports

For the purpose of this review, the marine environment has been classified into three physical zones - the littoral zone, the open-shelf environment and the coral reef. Since the boundaries are arbitrary, there will inevitably be some overlap, but for this review the subject matter will be related to the area between low water of ordinary spring tides and the edge of the continental shelf; i.e., to a depth varying to 200 metres.

Human influences may have a dual role in affecting the marine environment, firstly in a causative manner and secondly in providing a remedy, in which case the …

Telomere Structure In Euplotes Crassus: Characterization Of Dna-Protein Interactions And Isolation Of A Telomere-Binding Protein, Carolyn M. Price Jan 1990

Telomere Structure In Euplotes Crassus: Characterization Of Dna-Protein Interactions And Isolation Of A Telomere-Binding Protein, Carolyn M. Price

Department of Chemistry: Faculty Publications

The nucleoprotein structure of telomeres from Euplotes crassus was studied by using nuclease and chemical footprinting. The macronuclear telomeres were found to exist as DNA-protein complexes that are resistant to micrococcal nuclease digestion. Each complex encompassed 85 to 130 base pairs of macronuclear DNA and appeared to consist of two structural domains that are characterized by dissimilar DNA-protein interactions. Dimethyl sulfate footprinting demonstrated that very sequence-specific and salt-stable interactions occur in the most terminal region of each complex. DNase I footprinting indicated that DNA in the region 30 to 120 base-pairs from the 5' end lies on a protein surface; …

Recent Deposition Of 210pb On The Greenland Ice Sheet: Variations In Space And Time, Jack E. Dibb Jan 1990

Recent Deposition Of 210pb On The Greenland Ice Sheet: Variations In Space And Time, Jack E. Dibb

Earth Sciences

Detailed 210Pb profiles were determined for four "Chernobyl dated' snowpits sampled during a wide-ranging survey of the Greenland ice sheet during the 1988 season. The profiles from widely separated pits show little or no coherence; even for two pits only 40 km apart the profiles differ in detail. There does not appear to have been any seasonality in the deposition of 210Pb onto the ice sheet in the two years since the Chernobyl accident. The total deposition of 210Pb during this period (10-20 bq m-2) was about 20 times less than has been observed at mid-latitude sites in the eastern …


Gene Transfer In Crop Improvement - An Introduction And Overview, Robert M. Goodman Jan 1990

Gene Transfer In Crop Improvement - An Introduction And Overview, Robert M. Goodman

Journal of the Iowa Academy of Science: JIAS

The application of recombinant DNA technology to plant breeding promises important applications in agriculture and advances in many plant science disciplines. Gene transfer at the molecular level can be routinely accomplished in an increasing number of plant species. For many of the world's important crops, new methods or refinements of proven methods will be needed and are being developed. Experience with gene regulation in transgenic plants is accumulating in many laboratories around the world. The action of any particular gene cannot be predicted precisely without reference to the genetic background in which it acts, but, qualitatively speaking, the cis-acting elements …

Comparison Of Pressurized And Gravity Distribution Systems For Wastewater Treatment, Mark A. Gross, Stan Neal, Belinda Ederington, Robert Muldoon Jan 1990

Comparison Of Pressurized And Gravity Distribution Systems For Wastewater Treatment, Mark A. Gross, Stan Neal, Belinda Ederington, Robert Muldoon

Journal of the Arkansas Academy of Science

Pressurized distribution of domestic wastewater over a sand filter surface achieves better treatment than gravity distribution. The pressurized distribution system caused the filter to better remove organics (BOD₅) and suspended solids. Pressurized distribution also caused the sand filter to achieve more complete nitrification than the filter having gravity distribution. Two slow sand filters 15.2 cm wide, 3.1 m long and 15.2 cm deep were built and loaded with domestic septic tank effluent for 250 days at a rate of 5.1 cm per day. Influent and effluent samples were collected and analyzed for five-day Biochemical Oxygen Demand (BOD₅), suspended solids, ammonia- …

Photoacoustic Detection Of Carbonaceous Atmospheric Aerosols, Duane Jackson Jan 1990

Photoacoustic Detection Of Carbonaceous Atmospheric Aerosols, Duane Jackson

Journal of the Arkansas Academy of Science

The role of carbonaceous aerosols in the atmosphere as a risk factor in climatic changes and health effects and state-of-the-art monitoring processes are briefly presented here. In particular, development of a photoacoustic technique for measuring the concentration of carbonaceous particles is discussed. The photoacoustic measurement is based upon detection of pressure waves generated by localized time-dependent heating of air inside the photoacoustic chamber. Heating of air inside the chamber is due to absorption of visible laser radiation by carbon particles present inside the chamber. The laser radiation is chopped, and the resultant pressure signal produced by subsequent heating and cooling …


Effects Of Lake Management On Chemical, Physical, And Phycological Characteristics Of A Hypereutrophic Reservoir, Kaye J. Surratt Jan 1990

Effects Of Lake Management On Chemical, Physical, And Phycological Characteristics Of A Hypereutrophic Reservoir, Kaye J. Surratt

Masters Theses

Lake Charleston is a 1.1 billion gallon capacity side channel reservoir which was constructed in 1982 as a public drinking water supply for the City of Charleston in Coles County, Illinois. Past studies of the lake indicated an increase in eutrophication and the capacity to support large algal populations. Recent lake management practices include copper sulfate applications as an algicide and aeration to reduce flavor and odor.

In order to assess present lake status and to evaluate the effectiveness of lake management practices, two lake sites were sampled on a weekly basis from May to October, 1989. Chemical, physical, and …
