Some Design Considerations For Picture Archiving And Communication Systems, J. R. Cox, G. J. Blaine, R. L. Hill, R. G. Jost, C. D. Shum

All Computer Science and Engineering Research

Design considerations for picture archiving and communication systems are reviewed with special emphasis on those issues that differ from conventional network architectures. Design equations for three layers of a picture network are developed and discussed in the context of preliminary estimates of the flow of digital images between a multiplicity of picture sources, picture archives and picture viewing stations. Discussions of differences from conventional networks focuses on the local nature of the net, the availability of a wide-band transmission media with low error rates, the relative costliness of network equipment capable of taking advantage of the wide-band transmission media and …

Infiltration Through Reconstructed Surface Mined Spoils And Soils, A. D. Ward, Larry G. Wells, R. E. Phillips

Biosystems and Agricultural Engineering Faculty Publications

An extensive series of tests involving reconstructed profiles of spoil and topsoil material from a Western Kentucky surface mine site was conducted with a laboratory infiltrometer system. Infiltration through the reconstructed spoil profiles was very slow despite the coarse nature of the material. Low infiltration rates could be attributed to the material having a well-graded texture and to the high densities of the profiles. Infiltration through topsoil horizons was controlled, for the most part, by conditions at the surface. Following wetting, infiltration rates were primarily controlled by the hydraulic characteristics of the less permeable sub horizon of the spoil material. …

Analysis Of The Surface Polysaccharides Of R. Trifolii Su843 And Its Sym Plasmid Alterated Mutants, Jauh-Lin Duh

Masters Theses

The Rhizobium trifolii polysaccharides from SU843 and mutants--HC843(pBR1AN), HC843, 8002--in which the sym plasmid is replaced, absent, or mutated by transposon Tn5 were isolated. The surface polysaccharides of genetically altered mutants were compared quantitatively and qualitatively with one another and with the parent strain. The interpretation of these results is discussed in relation to the function of Rhizobium surface polysaccharides in the symbiotic process. The symbiotic ability of SU843 and mutant strains is as follows: (a) SU843, nod⁺, fix⁺; (b) mutant 8002, roa⁺ (still attaches to root hair), hac^-, nod^-; (c) …

An Experimental Investigation Of The Effects Of Crude Oil On Two Freshwater Lake Ecosystems, Martin D. Werner, V. Dean Adams, Vincent A. Lamarra

Reports

Responses of two freshwater lake ecosystems of the Intermountain West to crude oil impaction were investigated. The research was conducted in two phases; in the first phase effects of crude oil were studied on an ecosystem established in three phase laboratory microcosms (gaseous-aqueous-sediment), which simulated the natural lakes. Notable responses of the microcosm ecosystem to oil impaction included: an increased oxygen demand by the biological community, nutrient immobilization, a reduction in plant biomass accumulation and a heterotrophically dominated ecosystem. The increased availability of biologically degradable reduced carbon (i.e., the oil) and nutrient immobilization, rather than toxic effects of oil on …

The Evaluation Of Metals And Other Substances Released Into Coal Mine Accrual Waters On The Wasatch Plateau Coal Field, Utah, Alberta J. Seierstad, V. Dean Adams, Vincent A. Lamarra, Nancy J. Hoefs, Robert E. Hinchee

Reports

Six sites on the Wasatch Plateau were chosen representing subsurface coal mines which were discharging or collecting accrual water on this coal field. Water samples were collected monthly at these sites for a period of 1 year (May 1981 to April 1982). Samples were taken before and after each mine's treatment system. Water sampels were analyzed for major anions and cations, trace metals, physical properaties, nutrients, total organic carbon, oil and grease, trihalomethanes, and algal assay. Predictions were made as to the possible effects these coal mine accrual waters would have when used for drinking water, irrigation water, stock and …

Reports

Comprehensive planning is an elusive ideal. The practical planner must sort the relevant information from the vast amounts of data that modern technology can collect. The objective of this study was to use the Upper Blackfoot watershed in the mountains of Southeastern Idaho as an arena for developing methods for construction, refinement, and application of indices needed to design land and water management schemes, compare alternatives, and influence the public in their uses of the area. A total of 21 uses were examined on 242 land units of a 160 square-mile area ranging in elevation from 6300 to 9000 feet …

Evaluation Of The Potential For Groundwater Transport Of Mutagenic Compounds Released By Spent Oil Shale, Robert E. Hinchee, V. Dean Adams, Jeffrey G. Curtis, Alberta J. Seierstad

Reports

The major focus of this study was on the potential mutagenicity of aqueous leachates from spent oil shale. Additional mutagenicity testing was also done on raw shale and coal. The Ames salmonella microsomal bioassay was used to test for chemical mutagenicity. Spent oil sahles from the Paraho and TOSCO II processes, a raw shale from Anvil Points, and a composite coal sample from the Wasatch plateau were extracted with water and organic solvents. Only organic solvent extraction of the TOSCO spent shale resulted in a mutagenic response. The lack of mutgenic reponse to organic extracts of Paraho spent shale was …

Metal Ion Oxidative Decarboxylations. 13.¹ Kinetics And Mechanisms Of The Oxidation Of N-Benzyliminodiacetic Acid With Cerium(Iv) In Acidic Perchlorate And Acidic Sulfate Media2, Samir B. Hanna, Marilyn E. Moehlenkamp

Chemistry Faculty Research & Creative Works

The Ce(IV)-mediated decarboxylation of N-benzyliminodiacetic acid (BIDA) produces benzaldehyde, formaldehyde, dimethylamine, benzylmethylamine, and N-benzylglycine in acidic perchlorate and acidic sulfate media. Spectrophotometric evidence of an intermediate Ce(IV)-BIDA complex is given. The data may be interpreted in terms of a mechanism which involves sequential reactions, the first of which is a reversible reaction: BIDA + Ce(IV) (k1) ⇄ (k-1) complex (k2) → products. The rapid complex formation is followed by a slower oxidative decomposition to give a free radical capable of inducing free-radical polymerization. The free radical reacts rapidly with another Ce(IV) to give an iminium ion which undergoes either hydrolysis …

The Theory And Synthesis Of [2.2.2] Propellane, Theodore Mark Prociv

Dissertations, Theses, and Capstone Projects

INDO calculations indicated that the triplet state of dimethylene cyclohexane could rearrange to gometrically relaxed triplets which should collapse preferentially to the ground state [2.2.2] Propellane. A mercury sensitized photolysis of the dimethylene cyclohexane did in fact result in detectable quantities of the propellane, trapped as 1,4 dibromobicyclo octane. Synthesis of 1,4 dibromobicyclo octane and 1,1,6,6 tetradeuterodimethylene-cyclohexane are presented in the dissertation. Included in the dissertation are the results of INDO calculations of various propellane isomers having nitrogens and borons in the bridgehead positions.

Structure Of The Salina-Forest City Interbasin Boundary From Seismic Studies, Don W. Steeples

UMR Journal -- V. H. McNutt Colloquium Series

As petroleum exploration efforts in the Midcontinent become directed toward smaller fields and the search for minerals is extended into new areas, the edges of the Salina and Forest City basins will become of increased interest to industry. The principal boundary feature between the two basins is the Nemaha ridge, a linear feature that extends from near Omaha, Nebraska, to near Oklahoma City, Oklahoma. Recent seismic studies at the Kansas Geological Survey have revealed a complex array of faulted and folded structures in the vicinity of the Humboldt fault zone (the eastern flank of the Nemaha ridge). Faulting of both …

Kinetic And Spectral Studies Of Cobalt (Ii) -4, 4’, 4’’, 4’’’ –Tetrasulfophthalocyanine With Sodium Cyanide In Aqueous Solution, Pablo J. Diaz Cruz

Masters Theses & Specialist Projects

Kinetic studies of the cobalt (II)-4, 4’, 4’’, 4’’’-tetrasulfophtalocyanine and cyanide system were performed under argon and in air over temperature ranges of 294-314°K and 294-324°K, respectively. Two reactions were detected under argon. One was quite rapid and was followed on the stopped-flow apparatus. The results are consistent with the perturbation of a monomer-dimer equilibrium. The second reaction was slow enough to be followed spectrophotometrically on the Cary Model 14 spectrophotometer. The second order rate constant of 0.11 M^-1 sec^-1 at 294°K has been attributed to the rate of substitution of the second cyanide addition to a dye-cyanide …

Calculated Electrocapillary Curve For A Molten Salt, Jerry Goodisman, S Amokrane

Chemistry - All Scholarship

If bulk properties of simple molten salts may be reasonably well understood in terms of the primitive model, the situation with respect to surface properties is less satisfactory. It has been shown that a simple model for the distributions at the free surface of a molten salt can give surface tension and surface energy in reasonable accord with experiment, provided that a factor guaranteeing local electroneutrality is introduced. In this model, properties are given in terms of bulk-salt distribution functions, for which the primitive model is used. The present work extends this model to the electrocapillary curve, i.e., variation of …

The Marine Geochemistry Of Selenium, Kazufumi Takayanagi

OES Theses and Dissertations

A fluorometric method for the determination of Se (IV) and total selenium in natural waters has been developed and optimized. The detection limit is about 20 pM for both analyses using a one liter sample. The precisions were about 2 % at 338 pM for Se (IV) and at 234 pM for total selenium.

The concentrations of both total selenium and Se (IV) decreased with increasing salinity in the surface waters of the James River and southern Chesapeake Bay. While total selenium seemed to exhibit conservative behavior at salinities above 0.36 ('o)/oo, Se (IV) was apparently removed during estuarine mixing. …

Explicit Determination Of The Complex Refractive Index Of An Absorbing Medium From Reflectance Measurements At And Near Normal Incidence, R. M.A. Azzam

Electrical Engineering Faculty Publications

Measurement of reflectance at normal incidence R and its fractional change ΔR/R caused by a change of the angle of incidence from 0 to a small angle ϕ (ϕ≲ 20°) permits explicit determination of both the refractive index n and extinction coefficient k of an isotropic absorbing medium. The medium of incidence (ambient) is assumed to have a known refractive index (e.g., =1 for vacuum or air), and the incident light is either p or s linearly polarized.

Stationary Property Of Normal-Incidence Reflection From Isotropic Surfaces, R. M.A. Azzam

Electrical Engineering Faculty Publications

The complex reflection coefficients for the parallel (p) and perpendicular (s) polarizations of light that are normally incident upon an isotropic surface are proved to be stationary with respect to small changes of the angle of incidence in the neighborhood of zero. This is true not only for a single interface between isotropic media but also for any one-dimensionally inhomogeneous or multilayer reflecting structure that is stratified in the direction of the surface normal. For incident light of certain intensity, phase, and polarization, the intensity, phase, and polarization of the reflected light all remain stationary with …

Atrazine Degradation, Sorption And Bioconcentration In Water Systems, Duane C. Wolf, Ramon L. Jackson

Arkansas Water Resources Center Technical Reports

The herbicide atrazine is used extensively to control broadleaf and grass weeds in such crops as sorghum and corn. A small portion of the atrazine may be lost from the area of application by surface runoff and could enter a stream or lake. The objective of this study was to evaluate atrazine degradation, sorption, and bioconcentration in watersediment systems. The results indicated that sediments with lower pH values and higher organic matter levels adsorbed higher levels of atrazine than sediments with neutral pH values and lower organic matter levels. Microbial decomposition of the herbicide was slow under the conditions of …

Brewster And Pseudo-Brewster Angles Of Uniaxial Crystal Surfaces And Their Use For Determination Of Optical Properties, M. Elshazly-Zaghloul, R. M.A. Azzam

Electrical Engineering Faculty Publications

Brewster and pseudo-Brewster angles are defined for surfaces of transparent and absorbing uniaxial crystals parallel and perpendicular to the optic axis. Two Brewster angles of a transparent uniaxial crystal surface parallel to the optic axis, measured when the optic axis is oriented perpendicular and parallel to the plane of incidence, readily determine the ordinary and extraordinary indices N_o and N_e. N_o and N_e can also be obtained from two Brewster angles measured on a surface perpendicular to the optic axis in contact with two media of different refractive indices. Conditions for the existence of two …

The Visual Decision Making Process As A Technique For Redistributing Outdoor Recreation Use, Martha Gail Hahn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The demand for recreation on public lands has been growing steadily, resulting in undesirable impacts on certain resources as well as recreation experiences. The problem addressed by this research is the uneven distribution of recreational use that causes a concentration of impacts. This thesis describes the development and testing of a method to reduce the uneven/concentrated recreation use occurring on the public lands.

The basic objectives of the study were to determine the effectiveness of redistributing recreationists by the use of photographs and a decisional process using photographic information and to identify its potential as a tool in meeting management …

The Regioselective 3-Alkylation Of Piperidine, Richard Dunn Todd

Chemistry & Biochemistry Theses & Dissertations

The compounds: 3-allylpiperidine, 3-ethylpiperidine and 3-n-butylpiperidine have been synthesized by regioselectively alkylating the three position of piperidine. Piperidine was converted to N-chloropiperidine and then dehydrohalogenated to produce Δ¹-piperideine. The enamide anion was generated by adding solutions of Δ¹-piperideine to ethylmagnesium bromide or lithium diisopropylamide. Addition of alkylhalides produced 3-alkyl- Δ¹-piperideine which could be reduced or alkyllithiated to give 3-alkylpiperidines or 2,3-dialkylpiperidines respectively.

The yields of products were low and the reaction generated a continuum of mono- and di-alkylpiperidines and there was evidence that several dimeric piperideines were formed. The low yields were discussed in …
