Some Remarks On A Paper Of Aronszajn And Panitchpakdi, Melvin Henriksen Jan 1957

Some Remarks On A Paper Of Aronszajn And Panitchpakdi, Melvin Henriksen

All HMC Faculty Publications and Research

In the paper of the title [1], a number of problems are posed. Negative solutions of two of them (Problems 2 and 3) are derived in a straightforward way from a paper of L. Gillman and the present author [2]. Motivation will not be supplied since it is given amply in [1], but enough definitions are given to keep the presentation reasonably self contained.


Biological Indices Of Water Pollution, With Special Reference To Fish Populations, Peter Doudoroff, Charles E. Warren Jan 1957

Biological Indices Of Water Pollution, With Special Reference To Fish Populations, Peter Doudoroff, Charles E. Warren

Other Publications in Wildlife Management

A number of investigators have very recently published discussions having to do with biological indices and biological measures of water pollution (1) (2) (7) (13) (14) (15) (16) (26) (27) (28) (29) (30) (36) (38). Fjerdingstad (12) has discussed some of the pertinent European literature. The fundamental concepts presented by these authors are not original, for the idea that aquatic organisms can be useful "indicators" of environmental conditions, and particularly of the degree of pollution of water with organic wastes, has a long history (12). Because of certain novel features and the relatively wide scope of the studies, and the …


A 120 Megacycle Self-Contained High-Frequency Titrimeter, John Kyle Clinkscales Jr. Jan 1957

A 120 Megacycle Self-Contained High-Frequency Titrimeter, John Kyle Clinkscales Jr.

University of the Pacific Theses and Dissertations

The analytical chemist is ever eager to improve and expedite present analytical methods.. In the past ten years considerable interest .has been elicited in the field of high frequency oscillators and their application to analytical chemistry. One of the main reasons for this interest is the uniqueness of the apparatus. No direct contact is made between the measuring instrument and the solution. Credit tor this interest must be given primarily to Jensen and Parrack of Texas A & M University. Their article in 1946 described a simple tuned plate-tuned grid electronic oscillator, operating in the high frequency range. A solution …


On Minimal Completely Regular Spaces Associated With A Given Ring Of Continuous Functions, Melvin Henriksen Jan 1957

On Minimal Completely Regular Spaces Associated With A Given Ring Of Continuous Functions, Melvin Henriksen

All HMC Faculty Publications and Research

Let C(X) denote the ring of all continuous real-valued functions on a completely regular space X. If X and Y are completely regular spaces such that one is dense in the other, say X is dense in Y, and every f ε C(X) has a (unique) extension f E C(Y), then C(X) and C(Y) are said to be strictly isomorphic. In a recent paper [2], L. J. Heider asks if it is possible to associate with the completely regular space X a dense subspace μX minimal with respect to the property that C(μX) and C(X) are strictly isomorphic.


A Study In Predicting Success In Algebra, Leslie Milton Graham Jan 1957

A Study In Predicting Success In Algebra, Leslie Milton Graham

Dissertations and Theses @ UNI

Students of Manson High School at Manson, Iowa, select either algebra or general mathematics, subject to the approval of the principal. Some of the students' achievement records are incomplete, thus handicapping the principal in guiding the students to make their choices. As a result, several students have chosen to try algebra and have failed, and sometimes they have become discouraged and have left high school. It occurred to the writer that, if a predicting device could be established to show the student his chances in mathematics, it possibly could spare the pupil's failing in algebra.


Nebraska Deer, William Bailey Jr., George Schildman, Phillip Agee, C. G. Pritchard Jan 1957

Nebraska Deer, William Bailey Jr., George Schildman, Phillip Agee, C. G. Pritchard

Nebraska Game and Parks Commission: Publications

IN COMMON with the experience of most states, Nebraska's deer herds were reduced to a very low level by excessive harvests in our early history. Most American big-game animals were overharvested in the early history of this nation because of commercialization. Buffalo were killed for their hides, deer for their meat. This slaughter continued as long as the hunter (or poacher) could sell his take at a profit. Modem game management and public opinion reversed this trend. Deer are on the way back all over America, and in some states the protection-complex was so strong that deer were restored to …

The Value Of Including Chemistry Content In The Study Of High School Biology, Ramon Duane Buckley Jan 1957

The Value Of Including Chemistry Content In The Study Of High School Biology, Ramon Duane Buckley

Dissertations and Theses @ UNI

The purpose was to evaluate the effect of including some definite chemistry content in high school biology. This evaluation was made by comparing outcomes of instruction in two different groups of a high school biology course. The two groups were equated in terms of the intelligence quotients, the sex, and the previous achievement in biology of the class members. The comparative gains in factual knowledge were measured by means of an evaluation test. The comparative gains in appreciations and interests in biology were measured with a questionnaire.


Influence Of Various Factors On Aggregation Of Peorian Loess By Microorganisms, T. M. Mccalla, Francis A. Haskins, E. F. Frolik Jan 1957

Influence Of Various Factors On Aggregation Of Peorian Loess By Microorganisms, T. M. Mccalla, Francis A. Haskins, E. F. Frolik

Department of Agronomy and Horticulture: Faculty Publications

Soil structure is important in the attainment of adequate aeration for the aerobic microorganisms whose activities maintain such higher plant nutrients as sulfur, phosphorus, and nitrogen in a highly oxidized and thus readily available state. Good soil structure is also necessary for soil and water conservation, Under Nebraska conditions microorganisms and their decomposition products constitute a major source of soil-aggregating agents. The decomposition of crop residues and plant roots is important in the nutrition of these aggregating microorganisms. Other microorganisms, however, also utilize crop residues and plant roots, and they may decompose the aggregating agents as well, so that the …


Correlation Between Grades In Engineering Physics And Performance In Engineering Curricula, Donald Hoyt, Louis D. Ellsworth, Robert Katz Dec 1956

Correlation Between Grades In Engineering Physics And Performance In Engineering Curricula, Donald Hoyt, Louis D. Ellsworth, Robert Katz

Robert Katz Publications

A survey of grades in Engineering Physics I at Kansas State College showed that the inner structure of the course was highly consistent. The correlation coefficient between the average of the first three tests and the final grade was about 0.88. More significantly, valuable prognostic data could be obtained from the final grade in the course. The correlation coefficient between the Engineering Physics I grade and the final grade point average of students who completed the course was about 0.83. Only 21% of the students initially failing the course successfully completed an engineering degree, while about 75% of the A, …


On The Equivalence Of The Ring, Lattice, And Semigroup Of Continuous Functions, Melvin Henriksen Dec 1956

On The Equivalence Of The Ring, Lattice, And Semigroup Of Continuous Functions, Melvin Henriksen

All HMC Faculty Publications and Research

A large number of papers have been published that are devoted to showing that certain algebraic objects obtained by defining operations on the set of all continuous real-valued functions on a suitably restricted topological space determine the space. We mention but a few of them in this article.

Stream Pollution- Aquatic Macro-Invertebrate Communities As Indicators Of Organic Pollution In Lytle Creek, Arden R. Gaufin, Clarence M. Tarzwell Jul 1956

Stream Pollution- Aquatic Macro-Invertebrate Communities As Indicators Of Organic Pollution In Lytle Creek, Arden R. Gaufin, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

Year-round field studies of the com position and ecology of stream communities associated with the purification of organic wastes in streams were initiated on Lytle Creek in October, 1949. This creek, which is located about 45 miles northeast of Cincinnati, Ohio, is a tributary of the Little Miami River. Its drainage basin comprises 27 sq. mi., a third of which is contained within the city limits of Wilmington, Ohio, a city of some 7,412 persons

On Rings Of Bounded Continuous Functions With Values In A Division Ring, Ellen Correl, Melvin Henriksen Apr 1956

On Rings Of Bounded Continuous Functions With Values In A Division Ring, Ellen Correl, Melvin Henriksen

All HMC Faculty Publications and Research

Let C*(X, A) denote the ring of bounded continuous functions on a (Hausdorff) topological space X with values in a topological division ring A. If, for every maximal (two-sided) ideal M of C*(X, A), we have C*(X, A)/M is isomorphic with A, we say that Stone's theorem holds for C*(X, A). It is well known [9; 6] that Stone's theorem holds for C*(X, A) if A is locally compact and connected, or a finite field. In giving a partial answer to a question of Kaplansky [7], Goldhaber and Wolk showed in [5] that, with restriction on X, and if A …


Some Remarks About Elementary Divisor Rings, Leonard Gillman, Melvin Henriksen Jan 1956

Some Remarks About Elementary Divisor Rings, Leonard Gillman, Melvin Henriksen

All HMC Faculty Publications and Research

By a slight modification of Kaplansky's argument, we find that the condition on zero-divisors can be replaced by the hypothesis that S be an Hermite ring (i.e., every matrix over S can be reduced to triangular form). This is an improvement, since, in any case, it is necessary that S be an Hermite ring, while, on the other hand, it is not necessary that all zero-divisors be in the radical. In fact, we show that every regular commutative ring with identity is adequate. However, the condition that S be adequate is not necessary either.

We succeed in obtaining a necessary …
