Management Of Native Deer In Nebraska, John H. Wampole, Edson Fichter

Nebraska Game and Parks Commission: Publications

Deer are on the increase in Nebraska. Reports of deer seen, of deer killed on highways, and of localized cases of damage to crops by deer have become increasingly frequent during the last ten years. Since Nebraska is not primarily a land of forests nor of great repute as a deer state, the presence of these mammals in more than rare occurrences arouses considerable interest-and creates new problems in wildlife management.

It is the purpose of these notes to answer some of the questions most commonly asked about deer in Nebraska, and to point out certain misunderstandings which have led …

A Scheme Of Analysis For The Ceric Rare Earths, Herschel Gordon Frye

University of the Pacific Theses and Dissertations

The elements numbered 57 to 71 have presented a problem in analytical chemistry unparalleled by that of any other group since their discovery over the span of the nineteenth century. The striking similarities in chemical behavior of the fifteen elements comprising this series have almost completely baffled analysts in every attack, and it is only with the increased use of those newer methods, best described as being of a strictly physical nature, that much real progress has been achieved. Where time-honored classical wet methods have failed rather disappointingly, newer methods based upon the use of the spectrograph and similar instruments …

Use Of Motion Pictures In Laboratory Dynamical Studies, Carl Bailey, Jaan Jurisson, M. Eugene Rudd

M. Eugene Rudd Publications

In student laboratory experiments in dynamics, as, for example, Newton's second law of motion or the conservation of momentum, it is, of course, highly desirable to allow motion with the least possible constraint and to observe the displacements of moving parts without using perturbing markers. This circumstance has led us to use motion pictures in the student laboratory for quantitative observation of rapid dynamic processes, a technique which is used in a well-known textbook.' The photographic method combines maximum freedom of movement with accurate observation of position as a function of time, if the camera frame speed is sufficiently high. …

Studies In Quantitative Paleontology Ii. Multivariate Analysis—A New Analytical Tool For Paleontology And Geology, Benjamin H. Burma

Department of Earth and Atmospheric Sciences: Faculty Publications

Multivariate analysis is the simultaneous comparison of three or more variables in order to determine the significance of their likenesses and differences. The technique has been in use for some thirteen years, but no simple account of the method has hitherto been available. An illustrative example from invertebrate paleontology is here used, but the method is applicable to any problem in geology involving several quantitatively known variables.

Preliminary Report On The Geology Of Colgrove Butte, Hettinger County, North Dakota, Thorsteinn Thorsteinsson

Theses and Dissertations

Colgrove Butte is a flat-topped erosional remnant with a cap of rock area of approximately 0.845 square miles, rising about 200 feet above the surrounding Missouri Plateau in northwestern Hettinger County, North Dakota. Its upper portion consists of flat lying fresh water deposits of White River (Oligocene) age, containing beds of hard limestone, marls, argillaceous limestones, calcareous clays, clays and sands. It is everywhere covered by a mantle of top soil 6 inches to 3 feet 6 inches thick. Below this topsoil, extending over approximately two-thirds of the caprock area of the butte, is a bed of hard limestone averaging …

Studies In Quantitative Paleontology: I. Some Aspects Of The Theory And Practice Of Quantitative Invertebrate Paleontology, Benjamin H. Burma

Department of Earth and Atmospheric Sciences: Faculty Publications

For some time there has been a noticeable trend toward a more strictly quantitative outlook in paleontology. In view of many special circumstances encountered in dealing with fossil material, there is a rather extended consideration here given to the theoretical background of the quantitative method as applied to fossil invertebrates. First there is a consideration of the relations between sampling theory and paleontology. This is followed by a discussion of variability in populations and the problem of inference from sample to population. A consideration is next given to the species concept and a comparison of the units which can be …

The Influence Of Certain Factors In Urine On The Viscosity Of Gelatin, Leonard Driss

Bachelors’ Theses

The aims of this thesis are four-fold:

1. To determine the apparent proteolytic activity of normal urine from day to day.
2. To determine the apparent proteolytic activity of a sample of 8-12 hours after emission.
3. To determine whether the ether extracts of normal urine possess apparent proteolytic activity.
4. To determine the effect of hyaluronidase on the viscosity of gelatin.

The Influence Of Certain Factors In Urine On The Viscosity Of Gelatin, Leonard Driss

Bachelors’ Theses

After reading the Masters Thesis of Mr. Herman L. Karl, the writer became interested in this problem and then took · up the study of the proteolytic activity of normal urine. Mr. Karl worked on the urine of pregnant women. Using gela­tin as a substrate, he hoped to find a difference in prote­olytic activity between the urine of a woman pregnant with a male fetus and the urine of a woman pregnant with a female fetus. His results were not conclusive but suggested that the problem of proteolytic action of urine should be studied under normal conditions.

Mississippian-Pennsylvanian Boundary Problems In The Rocky Mountain Region, James Steele Williams

United States Geological Survey: Staff Publications

A variety of paleontologic and stratigraphic problems are presented by rocks near the Mississippian- Pennsylvanian boundary in the central and northern Rocky Mountains. Stratigraphic sections of these rocks show diverse interpretations of fundamental concepts of stratigraphy and paleontology. In many places where Upper Mississippian rocks directly underlie Pennsylvanian rocks it is difficult to determine the precise location of the boundary between these units. Formations that straddle the boundary are very useful and satisfactory over large areas. Most geologists use various types of lithologic criteria to distinguish formations, but some appear to rely mainly on faunal data, unconformities, or attempts to …

The Possibility Of A Land Bridge Across Nebraska In Mississippian Time, E. C. Reed

Department of Earth and Atmospheric Sciences: Faculty Publications

The lithologic and paleontologic differences between the Mississippian sediments of the Mid-Continent region and those of the northern Rocky Mountain and Black Hills regions suggest either that the Mississippian seas were not directly continuous between these two regions or that sea connections were greatly restricted. The purpose of this paper is to present and analyze the available subsurface data in Nebraska and surrounding states in the light of this problem. The study is primarily lithologic. Mississippian sediments are known to be widely distributed in the subsurface of much of Iowa and Kansas, in southeastern and extreme southwestern Nebraska, and in …

An Investigation Of Phosphate Adsorption By The Clays Montmorillonite And Kaolinite /|Cby Gordon Richard Bradford, G. R. Bradford

Theses and Dissertations

Clay minerals have widespread application in industry and play an important role in plant life (2, 17). It is the adsorptive capacity of clay which determines largely its importance to man (2). The purpose of this investigation is to interpret the mechanism of adsorption of the phosphate anion by the two clay minerals montmorillonite and kaolinite. This particular system was singled out for two reasons: 1. It has agricultural significance. 2. It is believed that if the particular phosphate adsorption mechanism is understood it will aid in an understanding of many other adsorption phenomena associated with clay.

The Carbethoxylation Products Of P-Aminoacetophenone And P-Dimethylaminoacetophenone, Chao-Yuan Chu

Theses and Dissertations

The carbethoxylation product of p-aminoacetophenone with diethyl carbonate by means of sodium amide has been proved to be ethyl p-acetylphenylcarbamate instead of ethyl p-aminobenzoylacetate. Thus the amino group was shown to be more active than the methyl ketonic. group tow ard carbethoxylation. Attempt at further carbethoxylation of this carbamate were unsuccessful.

The Fort Union Formation Of Montana And Adjacent Areas, Charles Christman

A Discussion Of The Geology And An Isopach Map Of The Pennsylvanian System In Wyoming And Adjacent Areas, B. R. Alto

Bachelors Theses and Reports, 1928 - 1970

Pennsylvanian strata in Wyoming and adjacent areas have been the subject of much work and discussion. Most of the work has been due to the economic importance of the system as an oil producer in this region. Oil production from strata of Pennsylvanian age is rather recent history; and therefore, much of the available information is local­ized and incomplete.

An Isopach Map And A Discussion Of The Permian In Wyoming And Adjacent Areas, Willard Leskela

Bachelors Theses and Reports, 1928 - 1970

The accelerated post-war demand for petroleum products with resultant high prices and dwindling reserves has spurred producers to an extensive search for new fields and for ad­ditional production in known fields. Exploration and discov­ery is dependent on the collection and correlation of vast amounts of data both in the field and that found in liter­ature.

Roasting And Leaching Of Montana Chromite, Jerry D. Murphy

Bachelors Theses and Reports, 1928 - 1970

The United States, although the leading consumer of chromite, depends almost entirely on imports for its supply. Domestic production of chromite is limited, because high-grade imported ore is plentiful and inexpensive in normal times. There are several large deposits of chromite in the United States, representing millions of tons of low grade ore. These deposits form a strategic reserve that must be used in time of national emergency.

Sulfatizing Roasting Of A Copper Sulfide Ore, Walter D. Finnegan

Bachelors Theses and Reports, 1928 - 1970

At present copper sulfide ores are recovered by pyrometallurgical processes. While the recovery of cop­per from sulfide ores by hydrometallurgical means has long been considered attractive, the impurities, low re­covery and mechanical difficulties have kept this process from becoming commercial.

A Study Of The Diffusion Of Electroplated Coatings In The Solid State., Michael R. Writt

Bachelors Theses and Reports, 1928 - 1970

The term diffusion means an equalization or homogenization of diverse materials. Specifically ap­plied to metals, diffusion is the interchange of atoms. It is, in effect, an invasion of one crystal lattice by the atoms of one or more other crystal lattices. Therefore, the study of diffusion must involve the geometry and physics of crystal lattices as well as their energies.

A Study Of The Physical Properties Of Low Tin Solders, Cornelius P. Dwyer

Bachelors Theses and Reports, 1928 - 1970

In 1947, out of the 100,000 long tons of tin con­sumed in the United States, 25,000 tons went into solder. Tin plate took 39,000 tons while babbit, bronze and coll­apsible tubes accounted for approximately 17,000 tons. Solder ranked second to tin plate and required more than the next three major uses combined.

The Effect Of Manganese And Magnesium On The Hardening Of Copper-Aluminum Alloys, Robert M. Hansen

Bachelors Theses and Reports, 1928 - 1970

During recent years, duralumin and all aluminum alloys have been made the object of much discussion regarding their hardening mechanism. The commercial success of nearly all of the alloys of aluminum and mag­nesium is dependent on their ability to age or precipitation harden.

Oxygen Enriched Atmosphere Roasting, Clarence Wells Jr

Bachelors Theses and Reports, 1928 - 1970

The possible benefits of oxygen enriched atmosphere roasting have been known to metallurgists for many years, but only since the development of equipment and processes to produce cheap oxygen in very large amounts has much ser­ious consideration been given this matter.

Foraminifera From Pleistocene Beds Near San Pedro, California, R. F. Mitchell

Bachelors Theses and Reports, 1928 - 1970

The age of rocks found in drill cores, and consequently the depths to possible oil-bearing formations has in many localities been determined by micro-paleontologic studies during the past three decades. Of the different micro-fossils used in this work, foraminifera have been studied most, are the best described, and hence, by far the most helpful.

Radioactivity Of The Pre-Cambrian Section Of The Bourbon, Missouri, Well Core By Measurement Of The Total Hard Gamma Radiation, Paul E. Damon

Masters Theses

"In December of 1947 Mr. Robert Van Nostrand and the writer became interested in the problem of the distribution of natural radioactivity and the applications of radioactivity to geology. A cooperative survey of the literature on the subject was undertaken. Later the writer decided to follow up the survey with a research project. Consultations with Dr. Z. V. Harvalik of the Missouri School of Mines Physics Department, and Dr. E. L. Clark and Mr. O. M. Bishop of the Missouri Geological Survey, followed. The nature of the project was evolved when Dr. Clark, with the consent of the U. S. …
