Impact Of Urban Stormwater Runoff On The Water Quality Of The Subsurface Lost River, Bowling Green, Kentucky, Donald Rice
Impact Of Urban Stormwater Runoff On The Water Quality Of The Subsurface Lost River, Bowling Green, Kentucky, Donald Rice
Masters Theses & Specialist Projects
Bowling Green, Kentucky is located in a distinctive karst region, characterized by subsurface drainage. The Lost River is a large subsurface stream which flows beneath the city. It receives much of the stormwater runoff from Bowling Green, since most of the city's runoff is directed underground. Significant pollutants in Bowling Green's stormwater runoff were identified from water quality test results of storm event grab samples, and a composite sample, of runoff entering the urban By-Pass Cave. Water quality test results were also obtained from storm event grab samples, and a composite sample, of the Lost River at the Blue Hole …
Analysis Of Organic N-Chloramines In Chlorinated Drinking Water, John Po Wen Yang
Analysis Of Organic N-Chloramines In Chlorinated Drinking Water, John Po Wen Yang
Chemistry & Biochemistry Theses & Dissertations
This thesis describes the development of a sensitive method for the separation and quantitation of organic N-chloramines in chlorinated tap water. 5-Dimethylaminonaphthalene- l-sulfinic acid has been synthesized and characterized. It yields highly fluorescent dansyl derivatives on reaction with N-chloramines. Conditions of the derivatization were optimized for the detection of N-chloropiperidine at concentrations in aqueous solution of 10-7 M. The technique gives a quantity of derivative which is proportional to the concentration of chloramine present over the range examined (10-7 M to 10-4 M). High pressure liquid chromatographic separation of dansyl derivatives of amines and amino acids has …
Stratigraphy And Depositional Environments Of A Late Pleistocene Barrier Island Complex, Southeastern Virginia, Alan K. Jasper
Stratigraphy And Depositional Environments Of A Late Pleistocene Barrier Island Complex, Southeastern Virginia, Alan K. Jasper
OES Theses and Dissertations
The Norfolk, Kempsville, and Sand Bridge Formations beneath the HIckory Scarp of southeastern Virginia are reinterpreted as representing one glacio-eustatic transgressive cycle. The timing of this transgressive event is set during the earliest Wisconsinan. The formations were previously interpreted as unconformable overlying one another. The Norfolk-Kempsville unconformity is actually a diagenetic boundary. Evidence is presented which indicates that the Kempsville Scarp area should be reduced to member status or dropped entirely.
Computer Simulation Of A Dynamical Model Of The Water Molecule, Donald Greenspan
Computer Simulation Of A Dynamical Model Of The Water Molecule, Donald Greenspan
Mathematics Technical Papers
A new computer-orlented theory for molecular dynamics is applied to modeling the water molecule. The dynamical equations are derived from molecular stability properties and from aspects of modern particle theory, especially as it relates to the structure of the electron. Computer studies are described and discussed.
Monotone Technique For Periodic Solutions Of Differential Equations, S. Leela
Monotone Technique For Periodic Solutions Of Differential Equations, S. Leela
Mathematics Technical Papers
The existence of periodic solutions has received a great deal of attention in recent years [1,7-11,14]. In [8,11] the existence of solutions of first and second order PBVP (periodic boundary value problem) has been studied successfully by combining the two basic techniques, namely, the method of lower and upper solutions and the Lyapunov-Schmidt method. In [6,11-13] monotone methods are developed for obtaining extremal solutions of BVP as limits of monotone iterates. In the first order PBVP [11] the monotone method has a greater significance since each member of the sequence is a periodic solution of a first order linear equation …
The Effects Of Kepone On The Estuarine Copepod Acartia Tonsa, Judith Marie Wilson
The Effects Of Kepone On The Estuarine Copepod Acartia Tonsa, Judith Marie Wilson
Biological Sciences Theses & Dissertations
Due to the contamination of a 113 km reach of the James River, Kepone poses a serious environmental threat to the Chesapeake Bay. The purpose of the study is to determine the acutely toxic and sublethal levels of kepone for the copepod Acartia tonsa, and to investigate what effects those levels may have on filtration rates.
Kepone was determined to be acutely toxic to A. tonsa, with a 96 hour LC50 of 4.96 ug/1. Dunaliella tertiolecta was selected as the food source for the grazing experiments. Kepone concentrations of 0.046 ug/1 significantly (0.05 level) reduced the flltering rate …

Water-Soluble Material On Aerosols Collected Within Volcanic Eruption Clouds, David B. Smith, Robert A. Zielinski, William I. Rose, B. J. Huebert
Department of Geological and Mining Engineering and Sciences Publications
In February and March of 1978, filter samplers mounted on an aircraft were used to collect the aerosol fraction of the eruption clouds from three active Guatemalan volcanoes (Fuego, Pacaya, and Santiaguito). The samples were collected on Teflon (Fluoropore) filters with a nominal pore diameter of 0.5μm. The mass of air sampled by the filters ranged from 0.15 to 6.6 kg. The particulate material collected consisted of fragments of angular silicate ash and droplets of what is interpreted as dilute H2SO4 and HCl. After collection of the samples, each filter was rinsed with 60 ml of distilled-deionized …

Small Particles In Plumes Of Mount St. Helens, William I. Rose, Raymond L. Chuan, D. C. Woods
Department of Geological and Mining Engineering and Sciences Publications
Particles in the size range of 0.1–25 micrometers were sampled by aircraft carrying a quartz crystal microcascade in the Mount St. Helens plume on three dates in August and September 1980. Two of the sampling dates represented ‘typical’ emissions of the volcano between plinian eruptions. One sampling flight was made 1–4 hours before the small plinian eruption of August 7, 1980, when the plume had become discontinuous and visibly darker. Size distributions were determined, and individual particles were studied by using scanning electron microscopy. The plume sampled on August 7, before the eruption, contained mainly approximately 2 micrometer diameter silicic …
