A Two-Stage Postnikov System Where E₂ ≠ E In The Eilenberg-Moore Spectral Sequence, Claude Schochet Jun 1971

A Two-Stage Postnikov System Where E₂ ≠ E∞ In The Eilenberg-Moore Spectral Sequence, Claude Schochet

Mathematics Faculty Research Publications

Let ΩBPBB be the path fibration over the simply-connected space B, let ΩBEX be the induced fibration via the map ƒ : XB, and let X and B be generalized Eilenberg-Mac Lane spaces. G. Hirsch has conjectured that H*E is additively isomorphic to ΤοτH*B(Z₂,H*X), where cohomology is with Z₂ coefficients. Since the Elienberg-Moore spectral sequence which converges to H*E has E₂ = ΤοτH*B(Z₂,H …

A Study Of The Acetic Anhydride Method For The Determination Of Citric Acid, Russell Kent Odland Jun 1971

A Study Of The Acetic Anhydride Method For The Determination Of Citric Acid, Russell Kent Odland

Master's Theses

Citric acid is an important compound of many systems. Numerous methods, both qualitative and quantitative, have been used for the determination of the compound. Some of the biological systems investigated include fermentation studies, action on yeasts, antioxidant in fruits, additive in bakery goods and salad dressing preparations, amounts in vegetables, and others.The above examples are not complete; they only show the varied applications of citric acid. The purpose of this project was to investigate a quantitative spectrophotometric method using anhydrous conditions based on the citric acid-acetic anhydride-pyridine reaction. Conditions affecting the reaction were investigated and optimized for maximum sensitivity and …


Electron Densities For Homonuclear Diatomic Molecules From The Thomas-Fermi-Dirac Theory, Jerry Goodisman Jun 1971

Electron Densities For Homonuclear Diatomic Molecules From The Thomas-Fermi-Dirac Theory, Jerry Goodisman

Chemistry - All Scholarship

Electron densities are calculated from approximate solutions to the Thomas-Fermi-Dirac equation for homonuclear diatomic molecules. The accuracy of expectation values calculated from these densities is assessed. In general, one obtains fair agreement with self-consistent-field and experimental results, but this is insufficient when a property is a difference between electronic and nuclear contributions. An important example is the Hellmann-Feynman force on a nucleus, the net force necessarily being repulsive, as for closed-shell atoms. Forc and energy results for such a situation are compared with experiment. Finally, it is shown that a modified theory, previously applied to atoms, gives improvement in expectation …

Arctic Ecology: A Decade Of Experience, John F. Schindler Jun 1971

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 Jun 1971

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 Jun 1971

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 Jun 1971

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 Jun 1971

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 Jun 1971

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 Jun 1971

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 Jun 1971

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 Jun 1971

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 Jun 1971

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 Jun 1971

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 Jun 1971

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 Jun 1971

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 Jun 1971

The Future Of Anchorage, Claire O. Banks

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. Jun 1971

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 …
