Cavefish Population Status And Environmental Quality In Cave Springs Cave, Arkansas - Final Report Submitted To Arkansas Natural Heritage Commission, G. O. Graening, Arthur V. Brown

Arkansas Water Resources Center Technical Reports

This report summarizes the continuing effort to monitor environmental quality in the Cave Springs Cave Natural Area and to implement the Ozark Cavefish Recovery Plan. Last year’s report (Brown et al., 1998) identified certain environmental stressors, including a trend over 15 years of increasing nutrient pollution, a low cavefish population count of only 106, and the presence of heavy metals in the cave water and one semi-volatile organic compound (the phthalate DEHP at 500 ppb) in resident crayfish tissue. This year’s monitoring effort demonstrates that fecal coliforms continue to exceed Arkansas State Water Quality Standards (Regulation 2), sometimes by a …

Induced Changes In Solvent Structure By Phospholipid Monolayer Formation At A Liquid–Liquid Interface, R. A. Walker, D. E. Gragson, G. L. Richmond

Chemistry and Biochemistry

Vibrational sum frequency spectroscopy has been used in conjunction with dynamic surface tension measurements to study formation of a 1,2-dilauroyl-sn-phosphatidylcholine (DLPC) monolayer at a water–carbon tetrachloride interface. Surface tension measurements show that an aqueous solution of liquid crystalline phosphocholine vesicles (4.5 μM DLPC) requires several hours to form a tightly packed, fully equilibrated monolayer of DLPC monomers. Vibrational spectra of the interfacial region at different stages in the monolayer formation process indicate that the solvent structure undergoes dramatic re-organization as the monolayer forms. Initial adsorption of DLPC monomers severely disrupts the interfacial hydrogen bonding. Intensity in the OH …

A New Kind Of Transposal Square, A. Ross Eckler

Word Ways

In my article "Single and Double Transposal Squares" in the May 1980 Word Ways, I generalized the concept of word square, allowing one to rearrange the letters in each row and column to form a word. Double transposal squares of size three are ridiculously easy to construct. The one on the left below is perhaps the commonest one, consisting of six words each having more than a thousand occurrences in Kucera and Francis's Computational Analysis of Present-Day American English (1967): man 1207, him 2619, its 1858, was 9816, who 2252, not 4609.

An Assessment Of The Impact Of Ophthalmia Dam On The Floodplains Of The Fortescue River On Ethel Creek And Roy Hill Stations, A L. Payne, A A. Mitchell

Resource management technical reports

The area surveyed covered all of the floodplains of the Fortescue River, and Jigalong, Jimblebar and Carramulla Creeks which fall within Ethel Creek and Roy Hill stations. Two serious, distinct and largely unrelated environmental problems are evident on the area surveyed. The first problem is longstanding, severe landscape degradation in the form of almost complete loss of perennial vegetative cover and soil erosion (mainly scalding) due to historical overgrazing.

Aging And Stereoscopic Shape Perception, Thomas Dawson

Masters Theses & Specialist Projects

Past research on stereoscopic depth perception among the elderly has led to inconsistent findings. Some research on stereopsis and aging has found that younger and older adults are essentially the same in terms of their stereoscopic ability, while other research has found evidence of large differences. This past research has largely been limited to investigations of stereoacuity. The purpose of Experiment 1 was to extend this earlier research to compare how older and younger observers perceive the magnitude of stereoscopically defined depth intervals. Random-dot stereograms depicting sinusoidal surfaces were shown to seven younger (i.e., ages 30 and below) and six …

Analysis Of Galvanized Steel Plates Using Glow Discharge-Atomic Emission Spectrometry, Liang Wang

Masters Theses & Specialist Projects

Combining an intense emission source and a high-speed sputtering source in one, glow discharge atomic emission spectrometer (GD-AES) provides an efficient technique for analyzing surfaces, coatings and bulk solids. The purpose of our work is to explore the optimum lamp operation parameters of SA-2000 for analysis of galvanized steel plate and to investigate the method for qualitatively and quantitatively analyzing the zinc coating. Under the optimum experimental conditions found in our study, which are current of 19-21 mA; voltage of 900-1200 V; pressure 2.0-2.5 torr, the calibration curve is constructed, so that specific zinc concentration can be assign to the …

Comparison Of An Advanced Mercury Analyzer With The Cold Vapor Atomic Absorption Technique For The Determination Of Mercury In Coal, Dong Li

Masters Theses & Specialist Projects

For over 30 years the industry standard method for mercury analysis has been the cold vapor atomic absorption spectrometric technique (CVAAS). Recent developments in improving this technique have focused on procedures for concentrating mercury in the analyte or materials to improve detection. The LECO Corporation produces an Advanced Mercury Analyzer, the AMA-254, for analysis of the solid and liquid samples. The system allows for the thermal heating of the sample to decompose the sample and release mercury, which is concentrated in a gold amalgam. Thermal desorption of the mercury from the amalgam is detected by atomic absorption spectroscopy. A comparison …

The Effects Of Phosphorus Enrichment On The Dominant Phytoplankton Communities Of Chaney Lake, Kathy Tehrani

Masters Theses & Specialist Projects

Chaney Lake is a temporary karst wetland located in southern Warren County, Kentucky. Because of an impermeable chert layer between the surface and the porous limestone, Chaney Lake fills with water over the winter and spring and then gradually drains over the summer. Three experiments were conducted over the course of the 1998 flooding season to assess the effects of phosphorus addition on the phytoplankton community in Chaney Lake. Ten plastic-sided mesocosms were constructed and placed in the marsh area of the wetland at three different periods: early spring, early summer, and late summer. Phosphorus in the form of K2HPO4 …

Configurational Entropy And Collective Modes In Normal And Supercooled Liquids, Ulrich Zürcher, T. Keyes

Physics Faculty Publications

Soft vibrational modes have been used to explain anomalous thermal properties of glasses above 1 K. The soft-potential model consists of a collection of double-well potentials that are distorted by a linear term representing local stress in the liquid. Double-well modes contribute to the configurational entropy of the system. Based on the Adam-Gibbs theory of entropically driven relaxation in liquids, we show that the presence of stress drives the transition from Arrhenius to Zwanzig-Bässler temperature dependence of relaxation times. At some temperature below the glass transition, the energy scale is dominated by local stress, and soft modes are described by …

Fisheries Research Report No. 114 - The Western Australian Scallop Industry, D C. Harris, L M. Joll, R A. Watson

Fisheries Research Reports

Five separate commercial fisheries target the saucer scallop, Amusium balloti (Bernadi 1861) in Western Australian waters. While the average annual catch from these fisheries is around 600 tonnes of scallop meat, past catches have been highly variable with annual landings ranging from 150 to 4,400 tonnes of meat worth between $2 and $59 million. Consequently, scallops represent one of the larger single-species fisheries operating in Western Australia (WA).

A. balloti has a distribution spanning most of the WA coast, from Broome in the north around to Esperance in the south. Despite this extensive distribution, saucer scallops tend to be restricted …

Fisheries Research Report No. 115 - Statistical Analysis Of Gascoyne Region Recreational Fishing Study July 1996, Neil R. Sumner, Richard A. Steckis

Fisheries Research Reports

A survey of recreational fishers in the Gascoyne region of Western Australia was conducted in July 1996 to provide information required by fisheries managers. Catch rates, attitudinal, demographic and economic information from boat-based and shore-based fishers was collected by Fisheries Officers. Pink snapper (Pagrus auratus) was the primary species caught by boatbased recreational fishers in the region. Various species of whiting were the predominant catch from shore-based anglers. Most fishers interviewed (80%) supported the introduction of an upper limit on the amount of fish and fillets that a person could take away from the Gascoyne region for personal or family …

Dynamics And Asymptotic Behavior Of The Solutions Of A Nonlinear Differential Equation, Robert Palmer

Masters Theses & Specialist Projects

Initial value problems of the form dx/dt= t xP, x(a) = β are examined, first when p = 2. Applying Euler's method, a numerical approximation technique, when p = 2 for certain initial conditions produces a numerical solution which resembles a bifurcation diagram very similar to that produced by the logistic map. Comparisons of such numerical solutions to the logistic map are made, and a partial explanation of such numerical solutions is given. Then, the exact solution of the initial value problem with p = 2, for which the software package Mathematica 3.0 determines an explicit formula, is analyzed to …

An In-Depth Analysis Of Students' Academic Retention Abilities In Traditional And Alternative Calendar Schools, Jennifer Reece

Masters Theses & Specialist Projects

The adoption of an alternative school calendar is a widely discussed topic in education reform today. The need to help students retain more academic skills after summer vacation is one reason school districts are considering alternative calendars. A recent study by Nofsinger (1999) of elementary students used Curriculum-Based Measurement (CBM) probes to measure academic skills in the Spring and the Fall in both traditional and alternative calendar schools. This present study further analyzed data collected during Nofsinger's (1999) study to determine whether certain groups of students (i.e., high, middle, and low achievers) gained more benefit from traditional or alternative calendars. …

A Stochastic Analog To The Richardson's Arms Race Model, John Fricks

Masters Theses & Specialist Projects

In this thesis, a stochastic version of the Richardson's arms race model is developed through the method of birth-death processes. The expected value of the model is explored and shown to be analogous to the original deterministic arms race model. The numerical method of randomization is then expanded and applied to the stochastic model. A comparison is then made between outcomes of the deterministic and stochastic models.

Near-Threshold Measurement Of Integrated Stokes Parameters For Kr Excited By Polarized Electrons, B. G. Birdsey, H. M. Al-Khateeb, M. E. Johnston, T. C. Bowen, Timothy J. Gay, V. Zeman, K. Bartschat

Timothy J. Gay Publications

We have made high-accuracy measurements of the integrated Stokes parameters for resonance fluorescence from polarized electron-impact excitation of the ⁴p⁵5p[5/2] ³D₃ and ⁴p⁵5p [5/2] ³D₂ states of Kr. We report measurements in the region within 0.6 eV of threshold, which is below the first cascade threshold. We also present theoretical calculations of these Stokes parameters using a recently developed relativistic Breit-Pauli Rmatrix code. In well LS-coupled systems, nonzero values of the integrated Stokes parameter P₂ signal relativistic effects (like continuum spin-orbit coupling, i.e., Mott scattering). …
