A New Confidence Interval For The Mean Of A Normal Distribution, David Lee Wallace Jun 1971

A New Confidence Interval For The Mean Of A Normal Distribution, David Lee Wallace

All Master's Theses

A typical problem in statistical inference is the following: An experimenter is confronted with a density function f(x; ϴ) which describes the underlying population of measurements. The form of f may or may not be known, and ϴ is a parameter (possibly vector-valued) which describes the population. The statistician's job is to estimate or to test hypotheses about the unknown parameter ϴ. In this paper, we shall consider interval estimation of the mean of the normal density function.

The Enzymatic Oxidation Of Aldehydes By Xanthine Oxidase, Duane Beal Gregory Jun 1970

The Enzymatic Oxidation Of Aldehydes By Xanthine Oxidase, Duane Beal Gregory

All Master's Theses

As early as sixty years ago, the existence of an enzyme from mammalian tissues which catalyzed the oxidation of xanthine and hypoxanthine was recognized. The name given the enzyme was derived from its earliest recognized action, hence xanthine oxidase. Although little is known about the biological functions of the enzyme, the high affinity shown for xanthine and hypoxanthine may indicate that these are the most significant substrates biologically.

An Elementary Mathematics Curriculum Study To Determine If Achievement And Attitude Can Be Influenced By A Textbook Adoption, Elsie M. Railey Jan 1970

An Elementary Mathematics Curriculum Study To Determine If Achievement And Attitude Can Be Influenced By A Textbook Adoption, Elsie M. Railey

All Master's Theses

There is on the market a wide range of contemporary mathematics textbooks available. Textbooks approach mathematics differently and there is a variation in terms of the amount of time allocated to a topic, the development of elementary concepts and laws of arithmetic, and the amount of drill and repetition. The sequential development of the texts follows closely, but the scope and content differ significantly. Specifically, it is the purpose of this study to determine if there is a significant difference between series, as opposed to those in another mathematics series, in the variables of attitude and achievement. The two textbooks …

On The Theory Of Quaternions, Earle David Smith Aug 1969

On The Theory Of Quaternions, Earle David Smith

All Master's Theses

Ordered triplets serve to describe space geometrically just as ordered pairs serve to describe the plane. A multiplication can be defined on pairs consistent with the complex numbers. However, as this paper will show, one cannot define a multiplication on triplets which is consistent with the complex numbers.

The Effects Of Herbicides On Three Soil Inhabiting Blue Green Algal Species, Lee C. Darlington Aug 1969

The Effects Of Herbicides On Three Soil Inhabiting Blue Green Algal Species, Lee C. Darlington

All Master's Theses

The object of this study was to examine the effects of varying concentrations of 2, 4-D, Dalapon, and Tordon on the growth of several nitrogen-fixing blue-green algal species obtained from soil samples and grown under culture conditions in the laboratory.

The Reaction Of Ethylenediamine With Cobalt (Ii) Perchlorate And Oxygen In Dilute Aqueous Solutions, Robert J. Karmy Aug 1968

The Reaction Of Ethylenediamine With Cobalt (Ii) Perchlorate And Oxygen In Dilute Aqueous Solutions, Robert J. Karmy

All Master's Theses

Cobalt (II) perchlorate was reacted with ethylenediamine and molecular oxygen. Various mole ratios of ethylenediamine to cobalt (II) were oxygenated and studied by photometric, potentiometric, conductometric, magnetic susceptibility, freezing point depression, electron spin resonance and cobalt (II) extraction methods. The fact that the complex was brown in color, diamagnetic, contained ethylenediamine to cobalt to oxygen in a mole ratio of 4:2:1 was confirmed. The complex underwent elation to form a polymeric species with excess base. The complex could not be oxidized to a green paramagnetic complex by reacting it with sodium peroxydisulfate, potassium bromate, bromine or chlorine. Ammonia was added …

On Semigroup Rings, Lawrence Paul Runyan Aug 1968

On Semigroup Rings, Lawrence Paul Runyan

All Master's Theses

Some of the properties of semigroup rings are described, illustrated and proved in this study. In particular, the central problem focuses on how various properties of the semigroup and ring are reflected in the resulting semigroup ring.

Preparation Of Phenylsulphur Chloride Tetrafluoride, Dennis T. Sauer Aug 1968

Preparation Of Phenylsulphur Chloride Tetrafluoride, Dennis T. Sauer

All Master's Theses

The reaction of C6H5SF3, CSF and C12 was studied under a variety of conditions. The reaction run in the presence of a trace of water yielded C6H5SO2F and C1C6H4SO2F. The reaction run in stainless steel at 170°C yielded an amber solid believed to be a polymer with the empirical formula C6H3.67SF2. Chlorination of a C6H5SF3-CSF mixture in monel at 220°C yielded a yellow liquid tentatively identified as a mixture of the new species C6H5SF4C1, FC6H4SF4C1 and C1C6H4SF4C1.

A Comparative Study Of Inductive Influence On The Hydrolysis Of Beta-Thioglucopyranosides By Beta-Thioglucosidase And Beta-Glucosidase, Robert W. Miller Jr. Jan 1967

A Comparative Study Of Inductive Influence On The Hydrolysis Of Beta-Thioglucopyranosides By Beta-Thioglucosidase And Beta-Glucosidase, Robert W. Miller Jr.

All Master's Theses

A series of phenyl-D-thioglucopyranosides were prepared and characterized in order to determine the absolute specificity of the .B-thioglucosidase and B-glucosidese enzyme systems toward the th1oglucosidic bond. The specificity of B-glucosidase of almond emulsin toward oxygen linkage seems to be absolute, since no hydrolysis was observed by this enzyme system toward the phenyl-D-thioglucopyranosides. The P-th1oglucosidase system was found to hydrolyze only two of the thioglucopyranosides. It was apparent that only where the electron-attracting substituents in the phenyl group were strong enough to greatly weaken the strength of the sulfur linkage, as in the case of the nitro group, would there be …
