Investigation Of Length Changes In Prestressed Concrete Slabs With Outside Exposures, John Best

Masters Theses

"In general, pavements may be classed as being either rigid or flexible. The term “rigid pavement”, as commonly used in the United States, is applied only to wearing surfaces constructed of portland-cement concrete. All other types of pavements are classed as “flexible”. A pavement constructed of portland-cement concrete is assumed to possess considerable flexural strength which will permit it to act as a beam and allow it to bridge any minor irregularities which may occur in the base on which it rests, hence the term “rigid”….

In view of the experience and information gathered in over 50 years of road …

Filter Materials For Emergency Use In Diatomite Type Water Filters, Robert Wassell Mcleane

Masters Theses

"A completely different type of filter, using diatomaceous earth as the filter media, had been in use for many years for filtration of industrial liquids, however, the use of diatomaceous earth for water filtration purposes had been discouraged due to the rapid clogging of the filter material. "As late as 1930 it was reported that the very excellence of filtration with diatomite prevented its extensive use in water filtration except where complete elimination of bacteria and suspended matter is essential.”

Diatomaceous earth, however, seemed to exhibit the general properties the research groups were seeking; in the refined state it exhibited …

Transference Numbers Of Concentrated Manganous Chloride Solutions, Marshall L. Severson

Masters Theses

"Electrolytic conduction differs from metallic conduction only in the nature of the carrier of the current. In the case of metallic conduction the carrier is electrons. The passage of an electric current through an electrolyte occurs only by the movement of ions of opposite charge moving in opposite directions under an applied potential. The current carried by a particular ionic species is a direct function of the concentration, the charge on the ion, and the ionic mobility. A transference number is the fraction of the total current a given ion carries in a particular electrolyte undergoing electrolysis. The sum of …

The Magnitude And Directions Of Strains And Stresses In Edge Loaded Concrete Slabs, William M. Baldwin

Masters Theses

"The concrete industry in the United States represents one of the fastest growing segments of the national economy. Many reasons for this may be given, among which are, the durability of concrete structures, the local availability of a large portion of the materials used in concrete, and its wide range of adaptability to the designs of engineers and architects.

One of the most recent changes in concrete usage is the change from reinforced concrete to prestressed concrete. The term prestressed as used herein refers to any type of reinforced concrete in which the reinforcing material has a stress prior to …

Detection Of Low Energy Positive Ions By Scintillation Methods, Graydon J. Hanson

Masters Theses

"This thesis deals with the feasibility of efficiently detecting low energy positive ions, those with energies of less than several hundred electron volts, using phosphors.

The scintillation technique, first used visually and greatly improved in the last ten years by the use of a photomultiplier tube, has greatly advanced detection in high energy fields. The photomultiplier is capable of delivering milliampere pulses of current of short duration and these can be registered directly by the many electronic devices currently in use.

Extensive work has been done with phosphors which scintillate under which energy bombardment, due in part to their wide …

Determination Of Lattice Constants, And Thermal Expansion Coefficients Of Ti₂O₃ And Of Its Solid Solutions With Ti, Tatsuhiko Ejima

Masters Theses

"For the determination of the precise lattice constants of Ti₂O₃, it is very important to use a Ti₂O₃ as pure as possible.

Due to the formation of solid solution with titanium or oxygen, ranging from 32.5 to. 34.5% O₂ by weight in the Ti-O binary system, it is very difficult to get a pure Ti₂O₃ (33.8% O₂ by weight) in the laboratory.

To determine the precise lattice constants of pure Ti₂O₃, therefore, the extrapolation method was used.

This method computes the respective constants for pure Ti₂O₃ from the values obtained With Ti₂O₃-Ti solid solutions by extrapolation. To carry out such …

An Analysis Of The Qualifications Of Selected Business Students Who Graduated From Comstock, Michigan, High School To Determine The Adequacy Of Their Training, Esther Larsen Fellows

Masters Theses

The Problem and Its Background

Since the first World War, business training on the secondary level has steadily grown in the number of students enrolled and in importance. New inventions, recent legislation involving more record keeping, and rapidly growing industry has brought about the demand for more workers, especially for office workers.

In a survey made in 1954 for the Comstock School Board it was found that most of the graduates from Comstock High School begin working in offices without further training. Although 49 per cent of the graduates seek further education before beginning regular employment, only 30 per cent …

Determination Of The Effect Of Air-Entraining Agents On Certain Physical Properties Of Concrete At Early Ages, James Arthur Spilman

Masters Theses

"Air entrained concrete over the past eighteen years has received national recognition as a result of its satisfactory performance in highway concrete pavements and other concrete structures subjected to outside exposure.

Numerous highway departments over the entire United States have laid test slabs made of air entrained concrete. Among those to date are Pennsylvania, New Jersey, New York, Connecticut, Massachusetts, Vermont, Maine, Illinois, Missouri and California. The primary purpose in building these test slabs was to investigate their durability or resistance to freezing and thawing and the action of various salts on air entrained concrete. The results of the test …

Investigation Of The Current Distribution On An Antenna In A Waveguide, David J. Freeman

Masters Theses

"In a communication system composed of several networks and transmission systems, it is necessary for all parts of the system to be impedance matched so that medium energy transfer is possible.

One of the recent transmission systems which has been developed is the wave guide. With the advent of the wave guide the communication engineer is immediately faced with the problem of coupling existing systems and networks to his newly found mode of transmission.

Practically this coupling problem reduces to one of feeding radio frequency energy to the wave guide with some conventional transmission line such as a coaxial line. …

An Investigation Of The Vocal Phonic Abilities Of Children With Normal Speech And Articulation Disorders, Orville Wilson Wensley

Masters Theses

Introduction

Much of the recent literature dealing with the etiology and treatment of functional articulatory defects, has been concerned with perceptual aspects of the problem. Many clinicians feel that it is in the area of perceptual deficiences that most of the causes of articulatory defects occur, even though research does not support that opinion.

An Exploratory Study Of Differential Diadochokinesis, Marie C. Crickmay

Masters Theses

Introduction

In speech man is forced to use organs, muscles and groups of muscles whose basic function is to serve other purposes, namely, to chew, to suck and swallow, movements which are relatively slow and primitive in execution. But in articulate speech it is necessary to manipulate these same organs and muscles at a faster speech, and with far greater precision than was required of them in the performance of their basic function.
