Determination Of N,N'-Diphenylguanidine In Biological Tissues And Fluids Using High Pressure Liquid Chromatography, Edward Sidney Hunter Iii

Chemistry & Biochemistry Theses & Dissertations

N,N'-Diphenylguanidine (DPG) is a potentially toxic compound used in the vulcanization of rubber products. Distribution of DPG in hybrid mice (C57BL/6J interbred with DAB₂) was determined following intraperitoneal injection. Urine, fecal material, whole blood and tissues were collected at various times after administration of DPG and the extracts analyzed for DPG by high pressure liquid chromatography. Recovery of DPG from spiked urine and whole blood exceed 90%, however, the recovery of DPG from spiked tissue samples was approximately 70%.

DPG concentration in whole blood reached a maximum within ten minutes and rapidly decreased through 180 minutes after administration …

Depositional Environments Of Siliceous Laminites In The Laney Member Of The Green River Formation, Sublette County, Wyoming, Michael G. Rasmussen

Loma Linda University Electronic Theses, Dissertations & Projects

Siliceous shales of the Laney Member of the Green River Formation are exposed in outcrops around Fontenelle Reservoir in the northwest corner of the Green River Basin, Wyoming. An analysis of these shales is important to an understanding of the origin of laminites in the Green River formation. The shales are rhythmic, varve -like laminites, composed of quartz, authigenic potassium feldspar , dolomite, and zeolite minerals. The association of these minerals suggest that the original sediment contained significant amounts of volcanic ash, and were deposited in a shallow, near-shore, oxygenated saline - alkaline lake environment, as inferred from (1) the …

Palynostratigraphy Of The Eocene Little River Section, Grays Harbor County, Washington, Roy E. Jensen

Loma Linda University Electronic Theses, Dissertations & Projects

A total of 27 samples from Eocene marine rocks exposed along the Little River, Grays Harbor County, southwestern Washington were analyzed for palynomorphs. Strata studied included the Crescent Formation, "Sedimentary Rocks of Late Eocene Age", and the Lincoln Creek Formation. A total of 77 micro fossil types were identified of which 32 were pollen and spores, 24 fungal remains, 18 dinoflagellate cysts, and 3 miscellaneous micro fossils.

Design, Construction, And Testing Of A Microprocessor-Controlled Interface Between Analog Geophysical Equipment And A Digital Cassette Recorder, Mohd. Nawawi Mohd. Nordin

Masters Theses

A Digital Data Acquisition System (DDAS) microcomputer was designed and constructed to interface between a six-channel analog seismograph and a digital cassette recorder. The DDAS microcomputer is a relatively inexpensive microcomputer built around the popular Z-80 microprocessor chip. It is portable and has 26K bytes of memory. It was designed to convert analog data in to digital with some processing performed before storing on the digital cassette recorder, for later analysis. The same hardware or circuitry of the DDAS microcomputer can perform other functions and work with other geophysical equipment by changing the software of the microcomputer.

Transport Properties Of Ground State Nitrogen Atoms, James C. Rainwater, Louis Biolsi Jr., Kevin J. Biolsi, Paul M. Holland

Chemistry Faculty Research & Creative Works

Transport properties of dilute monatomic gases depend on the two body atom-atom interaction potential. When two ground state (⁴S) nitrogen atoms interact, they can follow any of four potential energy curves corresponding to the N₂ molecule; the X ¹Σ⁺_g, A³Σ⁺_u, ⁵Σ⁺_g, and ⁷Σ⁺_u curves. Transport collision integrals for the ¹Σ⁺_g and ³Σ⁺_u states have been calculated by representing the potentials for these states with the Hulburt-Hirschfelder potential. The⁵Σ⁺_g state has a …

The Metal In The Polarisable Interface Coupling With The Solvent Phase, Jerry Goodisman, Jean Paul Badiali, Martin Luc Rosinberg

Chemistry - All Scholarship

A quantum mechanical treatment of the conduction electrons of a metal in a polarisable interface shows that they can make an appreciable contribution to the electrical capacitance. Results for six metals are given, showing how differences in metal properties account qualitatively for experimentally observed differences in interfacial capacities, when the solvent is replaced by a dielectric film. To justify the neglect of solvent structure when metal properties are treated, the coupling between metal and solvent is discussed for orientable point solvent dipoles, and for a representation of the solvent polarisation by a pair of charged planes. The electron profile affects …

Activity Coefficient And The Einstein Relation, Peter T. Landsberg, Albert G. Guy

Aerospace, Physics, and Space Science Faculty Publications

A connection between the activity coefficient of current carriers and the Einstein relations is established by two methods, one based on normal semiconductor concepts and one based on irreversible thermodynamics. The connection holds for all densities of states, for Fermi degeneracy, and in the presence of heavy doping.

KWRRI Research Reports

Information on fluorescent dyes used for water tracing and the results of six studies are reported. Optical brightener, direct yellow, fluorescein, rhodamine (WT), and other dyes are described and the procedures employed in their use ·in the field and in equilibration experiments are discussed. Three of the six studies consisted of investigations of the equilibration with passive detectors of three of the dyes. The absorption of optical brightener on fabric detectors was apparently linear with concentration and with immersion time, while detectors became rapidly saturated with direct yellow. Equilibrium of fluorescein on charcoal detectors with an elutriating solution was not …

The Growth And Feeding Behavior Of Juvenile Spot, Leiostomus Xanthurus Lacepede, In The Nursery Region Of The James River, Virginia, John Thomas Mccambridge Jr.

OES Theses and Dissertations

The in situ growth and feeding behavior of juvenile spot, Leiostomus xanthurus Lacepede, was investigated for populations in the nursery area of the James River, Virginia. Growth of juvenile spot was found to be fairly rapid (11.34 mm/month, standard length) during their first summer in the nursery grounds, but it levelled off in the autumn. The mean size of spot after the first year was calculated to be 195 mm total length. The weight-length relationship was log W = -5.018 + 3.246(log L), where W = wet weight in grams and L = standard length in millimeters.

Juvenile spot appeared …

Mandibular Repositioning With Frankel Appliance Therapy, Clark E. Schneekluth

Loma Linda University Electronic Theses, Dissertations & Projects

A sample of twelve Frankel appliance (FR-2) treated patients, in the mixed dentition stage, were selectively chosen by an orthodontist based on the Class II correction and evaluated from before treatment and end of treatment laminagraphic and lateral cephalometric radiographs. The average treatment period was 22 months (1 yr. 10 mos.). The average pre-treatment age was 9.5 years with a range from 8 to 11 years old, while the average post-treatment age was 11.3 years with a range of 10 to 13 years.

Frankel appliance therapy was the only form of mechanics used in this study.

Palynology And Paleoecology Of The Fossil Butte Member Of The Eocene Green River Formation In Fossil Basin, Lincoln County, Wyoming, Robert A. Cushman Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

The palynoflora of the Fossil Butte Member of Green River Formation was studied to enhance our understanding of the depositional environment of ancient Fossil Lake. Forty-nine outcrop samples were collected from three measured sections representing the center, the margin, and intermediate areas of Fossil Lake. Of the 49 samples, 12 yielded a fairly well preserved palynomorph assemblage.

A late early Eocene to early middle Eocene age for the Fossil Butte palynoflora is indicated by the presence of Bombacaceae, Eucommia, Ilex, Juglans, Pistillipollenites, Platycarya, Pterocarya, Tilia, and Taxodium. Additional evidence for the early to middle Eocene age of the Fossil Butte …

Photochemical Energy Storage (Photosensitized Isomerization Of Norbornadiene To Quadricyclane By Copper(I) Complexes), Dennis J. Fife

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research has focused on the sensitized photoisomerization step of a solar energy storage system based on the interconversion of norbornadiene (NBD) and quadricyclane (Q). Sensitizers studied in the photoisomerization were arylphosphine complexes of copper(I) halides [(Ph₃P)₃CuX, (MePh₂P)₃CuX, (DIPHOS)CuCl; X = Cl, Br, I and DIPHOS = Ph₂P(CH₂)₂PPh₂]. The lowest electronic excited state of the complexes can be an effective triplet energy sensitizer as evidenced by a maximum quantum yield of 1.0 with (MePh₂P)₃CuX. The sensitization mechanism of the L …

Effects Of A Wildfire On Seed Rain And Soil Seed Reserve Dynamics Of A Good Condition Sagebrush-Grass Rangeland In Central Utah, Mohamed Ali Hassan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objectives of this research were to investigate the ecological importance of soil seed reserves and seed rain on regeneration of a good condition sagebrush-grass range vegetation after a wildfire and draw conclusions leading to better understanding and management of such ecosystems. Investigations were conducted for two successive years on a community where major plants were neither rhizomatous nor sprouting. In such cases soil seed reserves and seed rain have to be the main source of regeneration. In addition to monitoring soil seed reserves and seed rain, vegetation changes during the past two years and the historical conditions of the …

Cargo Preference: Bitter Pill For The U.S. Public Or Pillar Of Strength For The U.S Merchant Marine?, Rand D. Lebouvier

Marine Affairs Theses and Major Papers

Leading with a brief discussion of the need for federal aid in general, the background, impact, and prospects for the future of cargo preference will be examined. It will be demonstrated that federal aid, particularly in the form of Cargo Preference, is required to maintain the merchant marine. It will also be demonstrated that federal aid and policy in its present form is not sufficient to promote growth. There needs to be significant improvement in this area if the maritime industry is to become a successful and vital force once again. Though cargo preference comprises only one part of the …
