The Impact Of Regulation Upon The Oil And Gas Industries, Lee Carter

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

It is paradoxical that the oil and gas industries both ask for and resist the idea of regulation. Historic examples are given of how and why this is so. Since the Arab oil crisis of 1973, new and onerous rules for domestic producers have been introduced, first by improvization and more recently by a national energy plan. Both the good and bad features of the 1977 national energy plan are reviewed to generate words of commendation and words of warning about its effect on the oil and gas industries.

Dynamic Pullout Resistance Of Anchors Buried In Dry Sand, Chris John Veesaert

Masters Theses

"The vertical pullout resistance of buried anchors subjected to dynamic loading was investigated by means of a laboratory model study. A dry uniformly graded sand, compacted by vibration to 92% of its relative density, was used as the test medium. Tests were performed in a 24-inch square tank using 3.0 and 5.0-inch diameter half and full-anchors. The anchors were tested at depths ranging from 5.0 to 21.0 inches.

It was assumed that the dynamic failure mechanism of earth anchors was the same as the static failure mode, and not distinct behavior. Thus static tests, i.e., tests using a constant strain …

An Evaluation Of Productivity And Efficiency In Work Scheduling In A Public Works Department, Kraig L. Gordon

Masters Theses

“Managers throughout the world frequently associate the meanings of productivity and efficiency with the capabilities and performance of employees. This approach is limited since productivity entails far more than the output of the labor force. The factors affecting productivity need evaluating to determine the significance they plan in the overall process.

Industry has attempted to improve its productivity posture by utilizing a multitude of concepts. Some of these concepts are time and motion studies and process planning. However, in the public sector, literature shows that little has been attempted to improve the productivity in public organizations.

The greatest portion of …

Geology Of The Stateline District, Utah-Nevada, Terry Moore Collins

Masters Theses

"The rocks exposed in the Stateline District, Iron County, Utah and Lincoln County, Nevada, are Tertiary volcanics, which serve as hosts for gold and silver bearing quartz veins. The Miocene rhyolites and dellenites, a possible caldera, cupola-associated rock textures, and the faults and styles of deformations indicate the geologic setting of Stateline is in harmony with the tectonic framework of the southern Great Basin. Four map units, subdivided into nine members, are recognized. X-ray fluorescence analyses for SiO₂, TiO₂, Fe₂O₃, CaO, and K₂O differentiated the map units, while variations in the primary quartz, sanadine, plagioclase, biotite, hornblende, and total crystal …

Final-State Effects In Carbon Auger Spectra Of Transition-Metal Carbides, M. A. Smith, L. L. Levenson

Physics Faculty Research & Creative Works

The carbon Auger spectra of TiC, VC, and Cr₃C₂ are measured with a resolution of 1.2 eV. Background subtraction is performed, and a deconvolution technique is used to remove energy-dependent broadening from the spectra. An analysis of the data in terms of density-of-states calculations, x-ray emission work, and x-ray photoelectron data shows that final-state effects dominate the Auger spectra. For all of the carbides three peaks are identified as spectral terms resulting directly from final-state hole interactions. Other peaks appearing in the Auger spectra can be identified without final-state considerations. © 1977 The American Physical Society.

A Fluid Control System For The University Of Missouri--Rolla Nuclear Reactor, Billy Roger Mcpherson

Masters Theses

"Solid control rods and their movement through a reactor core present problems inherent in any moving machinery. The problems of binding, wear, and noise have to be dealt with in the usage of a solid control rod system. Therefore, an alternate system that eliminates or minimizes these problems would lower maintenance costs, extend the lifetime of the control system, and produce safer operating conditions.

This thesis presents a control system that has no moving parts inside the reactor core. The system is based upon a neutron-absorbing fluid containe��d in hollow tubes in the reactor core. The fluid level is operated …

A Model For Evaluating The Effect Of Energy Reductions On Industrial Production Facilities., Eugene Dale Manning

Masters Theses

"The Energy/Production Simulation Model (EPSM) was developed to determine the impact that energy reductions have on industrial production facilities. The total energy requirements for manufacturing activities are analyzed for their effects on important production, ii which involves accounting for energy shortages as the raw material flows through all manufacturing stages to finished product. The computer algorithm presented herein involves a feedback analysis from the viewpoint of the physical units of the plant or facility in question, and is designed to aid industrial managers in designing effective energy management programs"-- Abstract, p. ii

Probability Of Anomaly Expressions For Random Waveform Registration, George L. Bair, Gordon E. Carlson

Electrical and Computer Engineering Faculty Research & Creative Works

Registration by integral-square error correlation of one-dimensional Discrete Time waveforms which are treated as random processes with specified autocorrelation functions is considered. An important design parameter for this class of problems is the probability of anomaly (a false dip in the correlation function) because it gives an indication of system immunity to gross registration errors. Explicit expressions for this parameter are not possible, so bounds and approximations must be derived. Two upper bounds and an approximation for the probability of anomaly are derived here. The use of these expressions is illustrated by an example. The relative utility of these performance …

Signal Processing For The Multistate Myoelectric Channel, Philip A. Parker, John A. Stuller, R. N. Scott

Electrical and Computer Engineering Faculty Research & Creative Works

In the Multistate Myoelectric Channel, a Single Myoelectric Signal Source is Used to Control a Multifunction Powered Prosthesis. the Selection of a Prosthesis Auction Requires a Receiver to Process the Myoelectric Signal, Contaminated with Noise, and to Decide on the Basis of the Received Signal Which Function is Desired. Thus, the Channel Dearly Presents a Problem of Choice of Receiver and of Decision Strategy. Previous Solutions to This Problem Have Been Basically Empirical. in This Paper We Seek the Optimum Receiver Where Optimum is in the Minimum Probability of Error Sense. First a Model is Developed for the Bipolar Myoelectric …

Studies Of Vibrational Surface Modes In Ionic Crystals. I. Detailed Shell-Model Studies For The Unrelaxed (001) Face Of Seven Crystals Having The Rocksalt Structure, T. S. Chen, F. W. De Wette, G. P. Alldredge

Mechanical and Aerospace Engineering Faculty Research & Creative Works

We present a comprehensive, unified account of the lattice dynamics of unrelaxed (001) faces of seven crystals having the rock salt structure, three of which have an absolute gap between the acoustical and optical bulk bands (RbF, RbCl, and NaI) and four of which have overlap between these bulk bands (NaF, NaCl, LiF, and MgO). The results are obtained from calculations of the normal modes of a thin crystal film in which the ionic interactions are described by the rigid-shell model. An outline of the formulation of the shell model for the film is given, and the rapid convergence of …

Turbulence Structure In Drag Reducing Polymer Solutions, Gary Kent Patterson, Jack Chosnek, J. L. Zakin

Chemical and Biochemical Engineering Faculty Research & Creative Works

Longitudinal turbulence intensifies measured by split-film anemometry in degraded polymer solutions in pipe flow peaked much farther from the wall than longitudinal turbulence intensities in a Newtonian oil at the same Reynolds numbers. The peak values were at about the same level for the degraded solutions as for the oil but were higher and nearer the wall for fresh polymer solutions. Radial turbulence intensities were lower for the polymer solutions at all locations under all conditions. Drag reduction for the polymer solutions ranged from 1 to 21% based on Newtonian fluid of equal viscosity. For the fresh solutions the Reynolds …

Optimization Of Methanol Process By Flowsheet Simulation, S. H. Ballman, J. L. Gaddy

Chemical and Biochemical Engineering Faculty Research & Creative Works

Optimization of large complex chemical processes is a necessary step in economic design of these systems. Flowsheet simulation models afford an ideal mechanism for detailed optimization of these processes. The methanol process offers several interesting optimization variables (reformer temperature, pressure, and steam and carbon dioxide to hydrocarbon ratios; synthesis loop pressure, temperature, purge rate, and conversion) which require detailed models of the reaction kinetics. This paper presents the results of optimization of the intermediate pressure process using the PROPS model and the adaptive random search routine. The costs associated with performing such a detailed process optimization study are easily justified …

Proton Shift Additivity And Substituent Interaction Parameters, Donald W. Beistel, Gary Chappell, W. Daniel Edwards

Chemistry Faculty Research & Creative Works

The 4-substituted acetophenone family is characterized and its shifts are correlated with those of nine families of 1, 4-disubstituted benzenes reported previously. Then a simple mathematical model is derived to account for the proton magnetic resonance shifts within families of 1, 4-disubstituted benzenes. The model suggests that the substituents interact by σ-bond polarization. The polarization model rationalizes shift additivity and is consistent with the qualitative relationship between the number of valence electrons on a substituent and its capacity to induce shifts. © 1977, American Chemical Society.

Subsolidus Equilibria And Stabilization Of Tetragonal Zro2 In The System Zro2‐Al2o3‐Sio2, Charles A. Sorrell

Materials Science and Engineering Faculty Research & Creative Works

The irreversible reaction between zircon and alumina to form mullite and zirconia was observed to proceed very slowly at 1480°C, confirming the existence of a stable join between mullite and zirconia in addition to the join between mullite and zircon. Attempts to determine equilibrium assemblages in powder samples of several combinations of the constituents at 1300° and 1400°C were unsuccessful. Metastable tetragonal ZrO₂ was observed in fired powder samples containing kaolinite, in fired zircon‐alumina samples, and in calcined gels prepared from zirconyl nitrate, aluminum nitrate, and colloidal silica in water. Tetragonal ZrO₂ was the dominant crystalline phase in …

Suggested Chemistry Of Zinc Oxychloride Cements, Charles A. Sorrell

Materials Science and Engineering Faculty Research & Creative Works

Solutions of ZnCl₂ were prepared from ZnCl₂·nH₂O and by reaction of zinc metal with HCl. Specific gravities and pH values were determined as a function of composition. A ternary phase, 4ZnO·ZnCl₂·5H₂O, was precipitated when the ZnCl₂ solutions were diluted to a pH of 5.48 ± 0.05. Mixtures of ZnO with ZnCl, and HCI solutions were equilibrated in sealed containers and analyzed by X‐ray diffraction. The resulting phase diagram shows 2 ternary phases, 4ZnO·ZnCl₂·5H₂O (4·1·5) and ZnO·ZnCl₂·2H₂O (1.1.2), both of which are soluble …

Estimating Hourly Solar Radiation For One-Axis Tracking Focusing Collectors, Carl E. Bingham, David M. Posner, Jerry O. Bradley

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Performance simulations of focusing parabolic collectors are hampered by a limited amount of useful insolation data. Hourly values of total radiation on a horizontal surface are the most common data available from the National Oceanographic & Atmospheric Administration. This paper develops a method to convert this total horizontal radiation to direct radiation on the surface of the tracking collector.

Energy And National Security, William A. Myers Iii

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

On April 18 of this year, the President of the United States made a television address to the American people on the subject of energy. It was a somber talk. He described the energy situation facing this nation as "the greatest challenge that our country will face during our lifetimes" with the exception of preventing war. He went on to say that our efforts to deal with the energy crisis must be the "moral equivalent of war", and that the alternative to those efforts "may be a national catastrophe."

President Carter's talk was not the first Presidential energy message. There …

Valence-Band Information From The Auger Kvv Spectrum Of Graphite, M. A. Smith, L. L. Levenson

Physics Faculty Research & Creative Works

The Auger KVV and x-ray photoelectron valence-band spectra of atomically clean, well-ordered graphite are measured. After background subtraction is performed and a deconvolution technique is used to remove energy-dependent features from the Auger data, the transition density function is calculated for the graphite valence band. A comparison is made with other experimental work and with a density-of-states calculation. It is found that the transition density closely resembles the density of states if localized hole effects are considered. © 1977 The American Physical Society.

Evaluation Of Zinc Sulfate Electrolytes By Cyclic Voltammetry And Electron Microscopy, Bruce A. Lamping, Thomas J. O'Keefe

Materials Science and Engineering Faculty Research & Creative Works

A cyclic voltammetric technique has been developed for approximating the quantities of active chemical species present in zinc sulfate electrolytes. The experimental apparatus consisted of a Pyrex "H" cell, an aluminum cathode encased in a Teflon holder, a carbon anode and a mercurous sulfate reference electrode. Voltammograms were obtained using industrial, purified neutral leach solution (Cominco Ltd., Trail, BC) acidified to give a final concentration of 0.77 M Zn++ and 1 M H2SO4. The polarization curves were then evaluated and used as reference standards to compare with results obtained when various organic and inorganic additions were made. The deposit morphologies …

Energy Dependence Of Amorphizing Implant Dose In Silicon, John R. Dennis, Edward Boyd Hale

Physics Faculty Research & Creative Works

The radiation-induced transformation from crystalline to amorphous silicon was studied using ion implantation. The ion energy was varied from 20 to 180 keV for Li+, N+, Ne+, Ar+, and Kr +. The energy dependence of the critical amorphizing dose was determined by electron spin resonance. Comparison of the data with theoretical calculations of the energy density deposited into atomic processes showed good agreement. This energy-dependent agreement gave evidence that energy density is important to the transformation at both low and high implantation temperatures.
