Arctic Marine Terminals -- Some Environmental And Engineering Considerations, Robert L. Mccollom Jr., William W. Moore

UMR Journal -- V. H. McNutt Colloquium Series

Studies are presently underway to determine the technical and economic feasibility of various Arctic marine transportation systems, including ice-breaker super-tankers and submarine tankers. An important consideration in these studies is the design and construction of marine terminal facilities which will be suited to the unique problems of the Arctic. Factors which will significantly affect the design of proposed marine terminals include:

1) bathymetric configuration of the continental shelf;
2) influence of moving pack ice on artificial structures, both at the air-water interface and along the bottom;
3) lateral and vertical variations in soil conditions, including residual permafrost, which might adversely …

Arctic Oil And The S.S. Manhattan, Russell H. Venn

UMR Journal -- V. H. McNutt Colloquium Series

The discovery of oil on Alaska’s North Slope in 1968 not only focused attention on that remote part of our world, it set the stage for one of the most exciting and significant scientific expeditions of our time—the voyage of the ice breaking tanker SS Manhattan through the Northwest Passage.

In the space available I would like to discuss with you that historic expedition, how it came to be, and comment on the results, as we see them.

Oil And Gas Reserves In The Siberian Shelf, A. J. Eardley

UMR Journal -- V. H. McNutt Colloquium Series

The Arctic region must be the world’s largest storehouse of liquid and gaseous hydrocarbons, and the vast Siberian region, both “on land” and “off shore” must be considered with envy by the free-world’s geologists for its oil and gas potential. It is here estimated that the off shore continental shelf of U.S.S.R. Siberia contains a reserve of 200 billion barrels of oil and 500 trillion cut. ft. of gas. These very approximate figures come from meager data obtained from the literature on oil and gas discoveries in the Siberian Arctic, the basin location of these discoveries, and the projection of …

The Role Of The Independent In Alaska's Mineral Development, D. L. Simasko

UMR Journal -- V. H. McNutt Colloquium Series

In 68 years of oil industry history in Alaska, the independent has already played a substantial role. Eighty-three independent oil companies or operators have participated in drilling 82 exploratory wells or stratigraphic tests. Their activities extended from the discovery of first commercial oil at Katalla in 1902, to the extension of the Prudhoe Bay field in 1970. The success ratio for wildcat wells in Alaska is considerably higher than “outside,” and fields have all been major in statute, thereby reducing the cost per barrel of finding oil.

The most immediate deterrent to the success of the independent in Alaska is …

Maintenance And Operation Of Facilities And Equipment In The Arctic, Charles C. Norris, Charles W. Kelley, Carroll C. Livingston

UMR Journal -- V. H. McNutt Colloquium Series

This has been but a short sketch of a few of the problems attached to living and working in the Arctic. Much has been learned about this remote and hostile area of the world; there is much more knowledge and experience required, as has been demonstrated by the controversy surrounding the routing and construction of the Trans-Alaska Pipeline. Man’s progress depends not only on means for his survival, but also on deep ecological considerations and solid engineering.--Conclusion.

The Alaska Business Community's View Of The Development Of Alaska, William H. Scott

UMR Journal -- V. H. McNutt Colloquium Series

America has discovered Alaska!! Or maybe that’s just the way it seems to us Alaskans. Even though Secretary of State Seward bought the Great Land (that’s what Alaska means in native tongue) more than a hundred years ago, very little of its nature has drifted down to the “Lower 48”. That is until the great oil reserves were discovered on the now-famous North Slope. Only then was the fact of Alaska’s mineral wealth translated into something other than very general admissions that Alaska was the natural resource storehouse of the United States. Now one would naturally conclude that the Prudhoe …

The U.S. Army's Experience In Handling Petroleum In An Arctic Environment, Frederic Johnson

UMR Journal -- V. H. McNutt Colloquium Series

This article pinpoints the various facets that the US Military experienced in Petroleum Operations in the Arctic environment Since the Military were the pioneers in Arctic operations, this experience could prove invaluable if and when the TAPS pipeline is constructed. The article deals primarily with various problems which beset the pipeliners during the initial construction phases and the peculiarities experienced during operations. A slightly different aspect will be experienced, however, when the Oil Industry moves relatively hot crude oil through the pipelines with TAPS since the Military moved only clean product.

The article addresses above ground pipeline operations, problems encountered …

UMR Journal -- V. H. McNutt Colloquium Series

So, in conclusion ... our Air Crossroads of the World contemplates its future, from a similar position as that of the ancient Greeks, or later the city of Rome... and much later ... England — the trade center of its time, between East and West — North and South. In any event, we are in the enviable position of being able to determine our future. Aside from the tremendous growth and build-up factors, we are unique because of our urbanity ... nowhere else are the advantages of modern day living offered to the extent they exist here, while at the …

State Regulatory Controls On Oil & Gas, Thomas R. Marshall Jr.

UMR Journal -- V. H. McNutt Colloquium Series

Alaska oil and gas regulatory matters are under the jurisdiction of a three-man Oil and Gas Conservation Committee, all of which are state employees.

In the last 10 years State water bottoms in Cook Inlet have been leased, explored and oil production amounting to about 200,000 barrels a day has been established. Cook Inlet is subject to very high tides and heavy ice flows. Five Salmon runs also occur in the Cook Inlet. The average daily production rate per well in the Cook Inlet area is nearly one hundred times the national average.

The Prudhoe Bay oil field discovered in …

Geologic Considerations And Solid Mineral Potential Of Alaska, A. E. Weissenborn

UMR Journal -- V. H. McNutt Colloquium Series

In marked contrast to Alaska’s petroleum industry, production from the State’s mining industry has declined drastically. Despite favorable geologic conditions, mineral exploration and development have been held back by inaccessibility, rugged terrain, severe climate, and scarcity and high cost of labor. Changing economic and political conditions, improved exploration techniques, and the ever increasing demand for minerals have again directed attention to Alaska’s mineral potential. Important discoveries in British Columbia and Yukon Territory have further stimulated exploration in Alaska. The probability that significant discoveries will result is high.

The titaniferous iron ores of southeastern Alaska probably will be brought into production …

Alaska's Possible Petroleum Provinces, George Gryc

UMR Journal -- V. H. McNutt Colloquium Series

Petroleum is the major Alaskan source of energy immediately available to the United States. Petroleum accounted for 89 percent or about $219 million of Alaska’s total mineral production in 1969 estimated at nearly $245 million.

Alaska’s first oil field was discovered at Katalla in 1902. About 154,000 barrels of oil were produced from 1902 to 1933. From 1945 through 1952, 45 shallow core tests and 36 test wells were drilled in and adjacent to Naval Petroleum Reserve No. 4 in northern Alaska. Oil deposits with possible reserves of 72 to 112 million barrels and gas deposits with possible reserves of …

Preface, Paul Dean Proctor, Robert E. Carlile

UMR Journal -- V. H. McNutt Colloquium Series

Because this university, formerly under the well known title of Missouri School of Mines and Metallurgy, has contributed so much to the nation’s and world’s mineral supplies through the work of its well trained graduates, it was considered appropriate that a major symposium be held during its Centennial Year on one of the last major mineral frontiers of the United States......Alaska.

Preliminary planning for the symposium on “Alaska, Its Mineral Potentials and Environmental Challenges” began in the fall of 1969. In January, 1970, Robert E. Carlile and Paul Dean Proctor visited Alaska to meet with some of the petroleum and …

Sidelobe Suppression In Chirp Radar Systems, Stephen N. Honickman

Dissertations

Pulse radars extend target range detection by increasing the transmitted pulse width. On the other hand, target resolution is enhanced by reducing the system pulse width. These dichotomous requirements led to the invention of chirp radar systems which achieve greater target resolution for a given detectable range by frequency modulating the carrier frequency of the transmitted pulse. Along with the advent of chirp radars came the extremely simple and reliable technique of chirp signal generation known as "passive generation". However, one of the undesirable features of "passive generation" lies in the infinite time required for transmission of the resultant pulse, …

Local Mole Fraction Equations For The Excess Free Energy Of Mixing, Jose Mario Marina

Dissertations

An extensive study of local mole fraction equations aimed at obtaining a two parameter expression for the Excess Free Energy of miscible and immiscible systems has been undertaken.

Initially our approach was to modify existing equations by substituting those parameters reflecting interaction between like molecules by the pure component energies of vaporization. This resulted in a one parameter modification of the three parameter Wilson equation, which correlates data poorly and a two parameter modification of the NRTL equation which correlates binary miscible data with fair accuracy. A modification of the Scatchard-Hildebrand equation, where mole fractions are substituted by local mole …

A New Technique For Steady State And Transient Analyses Of Incompressible Flow Networks, George V. Catanzaro

Theses

A new technique for the calculation of the transient or the steady-state mass flow rate and pressure distribution in incompressible flow networks is presented. Employing the matrix method of network analysis, the nodal continuity and branch momentum equations are solved simultaneously to obtain explicit relations giving the unknown nodal pressures and branch mass flow rates. In this manner, the transient or the steady-state behavior of incompressible flow networks with arbitrary configuration having nodal sources and sinks as well as branch transducers can be determined. In contrast with the conventional steady-state network analysis methods, the new technique can be extended to …

A Study Of Heat Transfer And Inlet Flow Behavior In Molten Polymer Systems, Min Ho Choi

Theses

Two separate studies have been done in the present work: one to study the entrance effects in flow in molten polymer systems and the other to investigate the heat transfer to thermally softened flowing polymer.

The equipment for the entrance effect was designed to study the isothermal flow behavior of a polymer melt in the entrance region. The main object of this investigation was to find the entrance length for the melt to relax and to separate the pressure drop into viscous and elastic effect. Due to the failure in developing a proper pressure measuring device the experiment was not …

The Reaction Of O-Propylphenyl Azide With Di-N-Propylamine, Seyed Ziaeddin Razavi

Theses

Nitration of n-propylbenzene resulted in O-nitro-n-propylbenzene. Reduction of this compound gave o-n-Propylphenyl azide was prepared by diazotization of o-n-propylaniline followed by treatment with sodium azide.

Photolysis of o-n-propylphenyl azide in di-n-propyl-amine yielded two new azepines, 2-di-n-propylamino-3n-propyl-3H azepine and 2-di-n-propylamino-7-n-propy1-7H-azepine. Their structures were assigned on the basis of their physical properties (i.e. I.R., U.V., N.M.R., N.S. and elemental analysis).

Photolysis of the azide at room temperature gave 26.9% o-n-propylaniline and 4.3% 2-di-n-propylamino-3-n-propy1-3H azepine, but when the photolysis was carried out in the presence of the triplet photosensitizer (xanthen-9-one) the yield of o-n-propylaniline was increased to 34.6% and the yield of 2-di-n-propylamino-3n-propy1-3H-azepine …

Stability Analysis Of A Continuous Stirred Tank Reactor With An Autocatalytic Reaction, David Elliot Rosenberg

Theses

The basic principles of stability analysis are set forth, including the development of a mathematical model, steady state analysis, integration of the dynamic system equations, and predictions of transient responses. The equations for the mathematical model are developed for a continuous stirred tank reactor with a cooling jacket, containing an autocatalytic reaction, in unsteady state operation. These equations are numerically integrated to obtain a good picture of reactor dynamics about the steady state. State variable methods, including the classical linearization theorems and Lyapunov's Second Method, are utilized to predict bounds of stable reactor behavior. A discussion of the shortcomings of …

An Analysis Of The Behavior Of A Non-Newtonian Fluid In A Flow Reactor, Asahiro Ahagon

Chemical and Biological Engineering ETDs

Velocity, temperature and concentration profiles were derived for non-Newtonian laminar flow of a reacting species in a tubular reactor. The equation of motion based on a temperature dependent power-law fluid model and the energy equation with internal heat generation caused by a first order chemical reaction were coupled and solved simultaneously using numerical methods to yield the profiles. The assumptions made in this study were: constant physical properties of the fluid (density, thermal conductivity and heat capacity). fully developed flow, wall temperature and negligible diffusion. Compartmentalized calculations resulted in velocity, temperature and reactant concentration profiles for both the axial and …

Dynamic Measurements Of The GrüNeisen Coefficients Of Tantalum, Uranium, And Uranium-Molybdenum Alloys, James E. Gover

Nuclear Engineering ETDs

Hooke's Law, Newton's Law, and the Grüneisen Equation of State are combined to develop a non-homogeneous, displacement wave equation and the stress/displacement relationship for an isotropic solid in which there has been a time and spatially dependent change in thermal energy. These equations are applied to two solids that are in perfect mechanical contact. One of the materials has had its thermal energy changed along one direction by a high energy electron beam while the thermal energy of the other has remained unchanged. It was assumed that the time dependence of the thermal energy change could be approximated by a …

Numerical Simulation Of Partially Neutralized Relativistic Electron Streams., Ludwig Adam Gritzo

Nuclear Engineering ETDs

The self-focusing of partially neutralized relativistic electron streams {Bennett pinch) is briefly discussed, and analytic solutions for idealized sets of conditions are reviewed.

A computer code for the numerical simulation of the drifting of a relativistic electron stream through an initially neutral gas, with the concurrent production and motion of ions and secondary electrons, is discussed in detail. The simulation conditions are restricted to (1) electron streams whose transverse momentum is small compared with their longitudinal momentum, and (2) low gas pressures, where the background plasma current and current density are low compared with the injected current. Only those electromagnetic …

Comparative Study Of Lightweight And Normal Weight Concrete In Flexure, Mohammad Zareh

Dissertations and Theses

This investigation represents a comparative study of the flexural behavior of lightweight and normal weight concrete. Both theoretical and experimental moment-curvature characteristics of the tested specimens were used to study the flexural behavior.

A generalized computer program to determine the moment-curvature relationships of a singly reinforced rectangular concrete beam was developed.

For this limited study it was observed that lightweight concrete beams when compared to normal concrete beams achieve comparable moment capacity (about 92% of normal weight concrete) but exhibit higher deflections (about 40% more than normal weight concrete).

Sequences From Nonlinear Feedback Shift Registers., Richard H. Braasch

Electrical and Computer Engineering ETDs

1.1 General Aspects of Shift-Register Generated Sequences

An n-stage register is a device consisting of n consecutive two-state memory units controlled by a clock. At each clock pulse, the state ak (logical 1 or 0) of each memory stage, ak, is shifted to the adjacent stage of higher degree. A shift register may be converted into a code generator through introduction of feedback loops that compute a new shift register state based on the previous state of the register. This feedback shift register principle is illustrated in Figure 1-1.
