Mössbauer-Effect Studies Of The Phase Transitions In Antiferroelectric Pbzro₃ And Ferroelectric Pbti₀.₀₂Zr₀.₈O₃, James P. Canner, C. M. Yagnik, Robert Gerson, William Joseph James

Physics Faculty Research & Creative Works

The Mössbauer spectra were studied for the antiferroelectric compound PbZrO₃ and for the closely related ferroelectric PbTi_0.2Zr_0.8O₃. In both cases, a substitution of 5-mol% BiFeO₃ was made to permit the Mössbauer measurements. Little difference was found in the isomer shift in these compounds, whether they were in the ferroelectric, antiferroelectric, or cubic state, indicating that the bonding character is not affected by the transitions among the states. There was a pronounced and approximately equivalent dip in the recoil-free fraction at the Curie points of both the antiferroelectric and ferroelectric materials, associated with …

Gravity Investigations Over A Salt Structure Near Lübbecke, Northern Germany, Reinhard K. Frohlich

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

A detailed gravity survey was conducted parallel to the “Wiehengebirge” northwest of Minden in Northern Germany. The survey localized between Liibbecke and Levern a salt deposit, which is known as “Münder Mergel” salt of the Upper Jurassic. The salt deposit forms a cylindrical structure with an axis striking NWW. With a deep drill hole detailed interpretation was possible using the polygon method of TALWANI, WORZEL and LANDISMAN [1959], The section shapes of salt bodies under eight profiles show asymmetrical figures of two salt units. Both increase in thickness strongly to the northeast, where the salt is interrupted by a fault …

Arctic Ecology: A Decade Of Experience, John F. Schindler

UMR Journal -- V. H. McNutt Colloquium Series

A quick glance at the title of this presentation and the reader braces himself for another antipollution or “save-the-sod” type of discourse that has become so popular these days. I do not wish to detract from the importance or the need for such efforts but I would like to address myself to the the broader meaning of the term.

Ecology--the word comes from the Greek root “oikos” which means house or household. What I’d like to do is to tell you about this “house” I’ve been living in for the past 10 years.

The Environmental Challenges Facing Taps, A. V. Cardin

UMR Journal -- V. H. McNutt Colloquium Series

Before the potential benefits of the recent oil discoveries on the North Slope of Alaska can be realized, the oil must be transported to refining and marketing areas. The Alyeska Pipeline Service Company has the responsibility for the first step in this transportation—to design and construct the Trans Alaska Pipeline System. We will pipe the oil from the discovery areas near Prudhoe Bay to an ice-free, deep-sea tanker loading terminal at Valdez of the South Coast of Alaska. From Valdez the oil will be transported to the West Coast by tankers. This is the most feasible system of a number …

The Environmental Challenges Of Alaskan Mineral Development, Earl T. Hayes

UMR Journal -- V. H. McNutt Colloquium Series

To meet the challenges and to develop Alaska as a source of mineral and fuel resources that are essential to all of us, we must conduct the research and planning necessary to see that the environment is not abused. We cannot allow ourselves the luxury of thinking that we alone know what is best for Alaska. We must strive for cooperation -- cooperation between government and industry; between Federal and State governments; between the doer and the dreamer; and between the engineer and the ecologist. Remember, the quality of what we do today will determine the quality of Alaska in …

Mineral Potential Of Arctic Canada, R. G. Mccrossan, R. M. Procter

UMR Journal -- V. H. McNutt Colloquium Series

Canada is on the threshold of a major new phase in the development of its Arctic resources. The Prudhoe Bay discovery triggered a boom in northern petroleum exploration that is just getting into high gear this year. Mining activity also has greatly expanded in the last few years with some 73 active exploration programs underway and several large new mines just coming into production. The size of these ventures is indicated by ore reserves of two lead-zinc mines to the value of 900 million dollars at Pine Point in southern Northwest Territories, and 1.2 billion dollars at the Anvil property …

Arctic Pipelining -- Tough, Costly, But Feasible, William H. Pearn

UMR Journal -- V. H. McNutt Colloquium Series

The development of vitally important Arctic petroleum resources presents new and interesting challenges. Although the answers to some questions will undoubtedly undoubtedly go unresolved until considerable operating experience has accrued, we can improve our present insight through an awareness of the work performed by others under similar conditions. This presentation focuses on Soviet pipelining experience in arctic and subarctic regions of Siberia.

Drilling Problems Associated With Arctic Minerals, Robert L. Parker

UMR Journal -- V. H. McNutt Colloquium Series

With major involvements in Alaska, the experience gained from these operations reflect the success of talented personnel in meeting the challenges of climate, equipment, logistics, perma-frost, etc. Real concern stems from present delays in the Arctic program due to financing involved as well as increasing dependency of the United States upon these reserves in today’s market and supply situation.

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 …

The Future Of Anchorage, Claire O. Banks

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 …

Magnetostriction And Magnetic Breakdown In Cadmium, J. M. Carter, Don M. Sparlin

Physics Faculty Research & Creative Works

Studies of the monotonic magnetostriction of cadmium at 4.2 °K in applied magnetic fields to 70 kG have shown that the angular variation of an extremal point Hm is proportional to secθ. The magnitude of Hm is in close agreement with the onset of a breakdown orbit γ13 observed for the applied field within 35 °of the c axis. The range of observation of Hm coincides with the range of the orbit γ. © 1971 The American Physical Society.

Collision Cross Sections For The Excitation Of The Schumann-Runge Dissociation Continuum In Molecular Oxygen By 20-110-Kev Protons, John T. Park, F. D. Schowengerdt, D. R. Schoonover

Physics Faculty Research & Creative Works

Absolute cross sections for the excitation of the Schumann-Runge dissociation continuum of molecular oxygen have been obtained from inelastic energy-loss spectra induced by 20-110-keV protons incident on gaseous targets of molecular oxygen. Apparent differential energy loss cross sections, ionization cross sections, and total inelastic cross sections are also obtained from the energy-loss spectra. The proton energy-loss spectra have an energy resolution of about 2 eV. The energy location of the first peak in the energy-loss spectra of O2 is in general agreement with the findings of photo absorption and electron energy-loss-spectra measurements. The cross section for the Schumann-Runge dissociation continuum …

Mathematics and Statistics Faculty Research & Creative Works

This paper presents existence, uniqueness, and continuous dependence theorems for solutions of initial-value problems for neutral-differential equations of the form (equation omited), where f, g, and h are continuous functions with g(0, x0)=h(0, x0) = 0. The existence of a continuous solution of the functional equation z(t) =f(t, z(h(t))) is proved as a corollary. © 1971 American Mathematical Society.

Noble Gases Anomalies In Terrestrial Ores And Meteorites, B. Srinivasan

Doctoral Dissertations

"Analyses of the content and isotopic composition of xenon and krypton in terrestiral ores containing tellurium, selenium or iodine resulted in the following conclusions: 1. The double beta-decay half-life for ¹³⁰Te is 2.51 x 10²¹ years from analysis of tellurobismuthite from Boliden, Sweden and 2.83 x 10²¹ years from analysis of tellurides from Kalgoorlie, Australia. 2. The ratio of the double beta-decay half-life of ¹²⁸Te relative to that of ¹³⁰Te is ≥ 108 and ≥ 293 for Boliden tellurobismuthite and Kalgoorlie tellurides, respectively. 3. Selenium minerals and tellurium ores containing selenium exhibit ⁸²Kr excess attributed to the double beta-decay of …

The Oxidative Decarboxylation Of Polyaminocarboxylic Acids - Ii. A Comparative Kinetic Study Of The Oxidation Of Nta, Edta, Cdta And Dtpa With Cerium(Iv) In Sulfuric Acid Media, Samir B. Hanna, Rita Hessley, William H. Webb, William R. Carroll

Chemistry Faculty Research & Creative Works

The rates of oxidation of four chelating agents, NTA, EDTA, CDTA, and DTPA with Ce(IV), in sulfuric acid media, were determined spectrophotometrically by a stopped-flow technique. The reductive ability is in the order CDTA > EDTA > DTPA > NTA. The influence of varying the acidity of the medium was studied, and in each case a maximum in the rate constant vs. [H+] plot was observed. A possible interpretation of the reactivities and the influence of acidity is advanced. © 1971 Springer-Verlag.
