The Physiological Implications Of Bleaching Of Corals Off Southeast Florida, C. J. Reese, G. S. Kleppel, Richard E. Dodge

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

As part of an ongoing study of coral bleaching, observations were made of corals on reefs (ca. 8m) off John U. Lloyd Beach, Dania, FL, in December, 1987. Bleaching was evident in approximately 50% of Montastrea annularis, the dominant scleractinian coral species. Quantitative pigment measurements by HPLC show that bleached corals contained

Decline Of Coral Growth Rates At Negril, Jamaica, T. J. Goreau, Richard E. Dodge, P. D. Goreau

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Montastrea annularis heads were collected near Negril, Jamaica, along transects from open, normal reef conditions into the mouths of rivers draining the Negril Morass. Corals subject to turbidity (particulate peat and dissolved humic compouonds near rivers, re-suspended reef sediments away from them) were growing more slowly than those in normal circumstances. Surprisingly, corals growing fastest were slowing the most, and the slowest growers increasing growth rate. Linear regression analysis of growth trends over the past two decades revealed stable limit-cycle behavior: change of growth was inversely proportional to growth rate, with a very significant correlation coefficient of -0.92. We suggest …

Impact Of Biotechnology On Agriculture Productivity, Roger A. Kleese

Journal of the Iowa Academy of Science: JIAS

Biotechnology is a diverse array of technologies which today are in various stages of evolution and development. To understand them and the potential application of these technologies to agriculture, it is helpful to consider them in a historical perspective. In addition, it is important to understand the interdependence of biotechnologies on traditional, well developed technologies. The commercial development of biotechnology is more difficult than imagined even as recently as five years ago. Also, the problems being addressed generally demand a much better understanding of the physiology and biochemistry of the plant and animal systems under study. Nonetheless, there is a …

Seasonal Composition Of Benthic Diatom Associations In The Cedar River Basin (Iowa), Stephen P. Main

Journal of the Iowa Academy of Science: JIAS

This is the first detailed report on the taxonomy and ecology of diatoms in the portion of the upper reaches of the Cedar River basin in Iowa. This paper describes the diatom taxa from shallow benthic substrata collected quarterly between 11 October 1975 and 19 February 1977 at 14 sampling stations. Just over 500 frustules were counted from each of the 216 samples obtained. Analysis of water samples collected at the same time as the diatoms indicates these screams have alkaline hard waters rich in nutrients with extreme turbidity level fluctuation at irregular intervals.

The 281 diatom taxa identified represented …

Recompact Iowa Soil Materials Before Using As Liners For Waste Containment, G. J. Kluitenberg, R. Horton, M. L. Thompson, J. F. Mcbride

Journal of the Iowa Academy of Science: JIAS

Soil materials are often used in hazardous-waste disposal facilities to provide a physical barrier to leachate movement. Both existing soils and recompacted soil materials have been used in barrier construction. Solute transport experiments and measurements of saturated hydraulic conductivity were used to characterize the solute transport properties of three Iowa soil materials. Experiments were carried out by using undisturbed soil samples as well as recompacted samples. The experimental results show that recompaction greatly altered the solute transport properties of the three soil materials. It is concluded that recompaction is necessary for any of these materials to satisfy Environmental Protection Agency …

Resource Sharing: A Study Of Florida's Shared-Used Library Collections, Susan Anderson

CCAC Theses and Dissertations

Designed to provide library service for two or more different groups of library users in one library facility, shared-use or joint-use libraries are a unique aspect of library resources sharing. Thirteen examples of shared-use library collections in shared or joint-use library facilities in Florida were examined in this investigation. Special focus was placed on the perceptions of librarians who work in these libraries in order to determine how well the libraries meet the information needs on users and how successful the libraries are in conserving financial resources as a result of combined collections. A design of a special resource collections …

This was accomplished by evaluating the two finalists of those vendors who answered the district's Request for Proposal (RFP). Of the five vendors who responded to the RFP. CLSI and SIRSI were selected as the systems most likely to meet the needs of the media centers of the school district.

An overview and definition of IOLS was first discussed. This overview then related itself to the needs of the school …

Hardware Algorithms For Data Compression, N. Ranganathan

Retrospective Theses and Dissertations

Data compression is the reduction of redundancy m data representation in order to decrease storage and communication costs. Data compression techniques have been used in practice primarily through software implementations which fail to meet the speed and performance requirements of current and future systems. This Ph.D. dissertation presents a set of hardware algorithms for compression and decompression techniques and the results of detailed simulations performed to quantify the effects of incorporating such hardware in various architectural environments. A new pipelined algorithm for data compression applicable to static binary encoding schemes is presented. A fast hardware algorithm for decompression that uses …

Stratigraphy, Paleontology And Paleobiogeography Of Lower Vertebrates From The Cedar Mountain Formation (Lower Cretaceous), Emery County, Utah, Michael L. Pomes

Master's Theses or Doctor of Nursing Practice

Where present, the basal Buckhorn Member of the Cedar Mountain Formation (Aptian-Albian) separates the overlying main member from the mudrocks of the Tithonian Brushy Basin Member of the Morrison Formation. Without the Buckhorn, the mudrocks of the Cedar Mountain Formation appear to grade into those of the Morrison, so one is apt to call the entire sequence Morrison. Where the Cedar Mountain Formation appears to grade in to the Morrison, use of lower vertebrate teeth can provide an additional means to separate the Morrison from the Cedar Mountain Formation. Lower vertebrate teeth and associated microvertebrate remains (eggshell and bone fragments) …

Generating Multiple User Interfaces For Multiple Application Domains, Mahesh Hassomal Dodani

Retrospective Theses and Dissertations

This Ph.D. dissertation presents a classification scheme for User Interface Development Environments (UIDEs) based on the multiplicity of user interfaces and application domains that can be supported. The SISD, SIMD and MISD [S= Single, I= user Interface(s), M= Multiple, D= application Domain(s)] generator classes encompass most of the UIDEs described in the literature. A major goal of this research is to allow any user to develop a personalized interface for any interactive application, that is, the development of an MIMD UIDE.

Fundamental to the development of such a UIDE is the complete separation of the user interface component from the …

A Relational Object-Oriented Management System And An Encapsulated Object-Oriented Programming System, Michael L. Nelson

Retrospective Theses and Dissertations

The purpose of the Relational Object-Oriented Management System (ROOMS) is to show that the relational database scheme is a viable approach for storing objectoriented data. ROOMS is designed so that it can be implemented in any object-oriented language with appropriate I/O commands, or added to any objectoriented database management system that allows userdefined collections of data. Various problems were encountered in developing ROOMS. While these problems have been solved, the best solution is to use the Encapsulated Object-Oriented Programming System (EOOPS) . EOOPS is based upon an inheritance scheme which preserves encapsulation. This encapsulated approach avoids the problems associated with …

Thermal, Mechanical And Interfacial Characterization Of A Fiberglass Reinforced Plastic Composite, Theodore J. Williams

Masters Theses

The effects of a glass fiber reinforcer on the properties of poly(methyl methacrylate) were evaluated. A silane coupling agent (M8550 Petrarch Systems, Inc.) was employed to promote adhesion between the materials. FTIR analysis, ESCA/Auger and SEM techniques were used to characterize the silane coating.

The mechanical properties, such as bending strength, improved with an increase in the volume percent of fiber. The addition of the M8550 silane directly into the monomer solution showed the most improvement, 23 percent increase, when compared to the uncoated glass fiber. The glass transition temperature as measured by DSC and the heat distortion temperature (HDT) …

Determining The Distribution Of Hydraulic Conductivity 1n A Fractured Limestone Aquifer By Simultaneous Injection And Geophysical Logging, Roger H. Morin, Alfred E. Hess, Frederick L. Paillee

United States Geological Survey: Staff Publications

i\ field technique for assessing the vertical distribution of hydraulic conductivity in an aquifer was applied to a fractured carbonate formation in southeastern Nevada. The technique combines the simultaneous usc of fluid injection and geophysical logging to measure in situ vertical distributions of fluid velocity and hydraulic head down the borehole; these data subsequently are analyzed to arrive at quantitative estimates of hydraulic conductivity across discrete intervals in the aquifer. The diagnostic capabilities of the analysis were found to be constraincd by the accuracy and resolution of the logging tools as well as by the hydraulic characteristics of the formation. …

Development Of Solid Substrate Luminescence And Chromatographic Techniques For Chemical Analysis, William J. Long

Theses and Dissertations

Room Temperature Phosphorimetry (RTP) is a sensitive and selective technique which is well suited to the analysis of compounds of environmental and pharmaceutical interests. Absolute sensitivity is generally in the low to subnanograrn range. Selectivity of this technique is due to the fact that only several hundred compounds phosphoresce at room temperature. In these studies attempts are made to gain a greater understanding of the phenomenon of solid substrate room temperature phosphorimetry and to extend the application range of the technique.

This goal is approached through several directions, all leading to a greater understanding of solid substrate luminescence in general, …

Hydrogeology Of The Hillsboro Landfill, Hillsboro, North Dakota, Jeffrey D. Maletzke

Theses and Dissertations

Landfills are the primary means for land disposal of solid wastes, and as such, they represent potential sources of groundwater contamination. This potential for contamination is exemplified by the Hillsboro landfill, which was emplaced above the Hillsboro aquifer, within permeable surface materials, and under shallow water-table conditions. Burial of refuse in trenches 15-feet (4.57 m) deep ensure that at least portions of the refuse are below the water table, which varied from 5.4 to 13.2 feet (1.7 to 4.0 m) below the surface. Concern over these factors led to the present study.

Subsurface conditions were investigated by electrical, earth-resistivity surveying. …

A Parallel Implementation Of Stickel's Ac Unification Algorithm In A Message-Passing Environment, David John Kleikamp

Masters Theses

"Unification algorithms are an essential component of automated reasoning and term rewriting systems. Unification finds a set of substitutions or unifiers that, when applied to variables in two or more terms, make those terms identical or equivalent. Most systems use Robinson's unification algorithm or some variant of it. However, terms containing functions exhibiting properties such as associativity and commutativity may be made equivalent without appearing identical. Systems employing Robinson's unification algorithm must use some mechanism separate from the unification algorithm to reason with such functions. Often this is done by incorporating the properties into a rule base and generating equivalent …

Comparison Of Effective Medium Procedures For Optical Modeling Of Laminar Structures, David D. Allred, Robert F. Edgerton

Faculty Publications

This study addresses the question, "How can the optical properties of matter in ultrathin amorphous nonmetallic films in multilayers best be determined from reflectance (R) and transmission (T) measurements?" A blue shift in the band gap of plasma CVD a-Si:H/a-SiNx:H multilayers was reported several years ago. It was suggested that the shift in the band gap, Eg, Relative to bulk a-Si:H as given by the Tauç plot was due to quantum confinement effects. The purpose of this study is to evaluate the usefulness of various effective media theories (EMT) for determining the optical constants of materials in a multilayer and …

An Economical Field Datalogger, Norbert H. Maerz, M. B. Dusseault, R. W. Gillham

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Data acquisition is important in geotechnical and hydrological field investigations. Commercially available data acquisitions systems are often not well suited to field use, and can be costly. An alternative to buying a data acquisition system is to build one, and recent advances in computer micro-chip technology have made it easy to understand, design and build simple data acquisition devices.

The design of a data acquisition system developed at the University of Waterloo, along with an example of its use, is discussed in the paper. The intent was to sample 16 channels at 12 bit resolution for prolonged periods under adverse …

Microcomputer Image Analysis Of Rock Fabric, Norbert H. Maerz, C. P. Bennettt, B. A. Dony

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The behavior of many types of rock is largely dependent on the fabric of the rock mass. Current methods of manually measuring the discontinuity networks in rock masses are slow, tedious and error prone. The alternative is to make automated measurements of rock jointing parameters on digital images of rock faces in mines, tunnels, and surface excavations.

Photoanalysis techniques are being developed to measure various rock fabric parameters. Techniques presented here include the generation of a joint trace map from a photograph, and the measurement of simple statistics on the joint trace map. Methods are also presented for the determination …

Management Of Suburban Deer: An Emerging Controversy, Daniel J. Decker

Eastern Wildlife Damage Control Conference: 3rd (1987)

During the last 10 years the presence of deer (Odocoileus virginianus) in suburban areas has become an increasing concern from the standpoint of damage and nuisance problems. It is unclear whether (a) overall deer numbers in suburban environments have increased (possibly because of residential development in "natural" settings and creation of food sources represented by residents' ornamental plantings and vegetable gardens), (b) more development in suburban areas has forced deer into adjacent remaining patches of suitable habitat, resulting in increased deer densities in certain localities, or (c) some combination of both. Regardless of the factors perpetrating the situation, …

Temporal Use Patterns Of Wintering Starlings At A Southeastern Livestock Farm: Implications For Damage Control, J.F. Glahn, S.K. Timbrook, D.J. Twedt

Eastern Wildlife Damage Control Conference: 3rd (1987)

The farm use patterns of individually marked and transmitter-equipped starlings at a livestock farm in south-central Kentucky were studied each month during the principal damage period (December-February) of 1982-83 and 1984-85 following a pilot study in January and February of 1980. In addition to intensive observation at the farm, sightings of tagged starlings away from the farm were solicited from the public and mapped. For each year of data on individual starlings that used the farm at least once after marking, the expected frequencies of farm occurrence were calculated and compared to observed frequencies. In all 3 years, there was …
