Boehmite-Bonded High-Alumina Refractories, Gerhard H. Schiroky

Masters Theses

"High-alumina refractories (99+ % Al₂O₃) were produced by pressing a mixture of 70% tabular alumina and 30% reactive alumina and autoclaving in saturated steam at 1.4 MPa (200 psia)/194 °C to 3.4 MPa (500 psia)/242 °C for 12 to 96 h. Autoclaving converted the reactive alumina to boehmite which acted as the bond phase. At room temperature the MOR ranged up to 37 MPa depending upon boehmite content. The hot-MOR decreased steadily with increasing temperature, but was still 8 MPa at 1400 °C which exceeds that of comparable cement-bonded or conventionally fired high-alumina refractories. The estimated autoclaving costs are lower …

Processing Of Copper Refinery Anode Slimes, Shrirang Anant Kulkarni

Pelletizing Of A Lead Sinter Machine Feed, Hung-Yang Tsai

Masters Theses

"A typical lead sinter machine feed can be pelletized in a drum pelletizer using tap water as a binding liquid. The green pellets produced have return sinter as cores, and an outer layer of new material and fluxes. The moisture content of the pellets produced is about 5%. The pelletizing procedure developed used raw materials from the Amax Lead Smelter, with only a minor amount of feed preparation. The importance of proper moisture control, use of binders, method of adding moisture, speed of pelletizing drum, etc. were investigated. The stability of pellets under extreme storage conditions was also determined"--page ii.

An Outline Of The Procedures To Reduce Budget Expenditures In The Edwards County Community Unit School District No. 1 For The 1978-79 Fiscal Year, Gary J. Schurz

Masters Theses

The purpose of this study was to discover ways to reduce expenditures in the budget of the Edwards County Community Unit School District No. 1 for the 1978-79 fiscal year in the light of a projected loss of revenues complicated by inflationary trends.

The need arose due to three factors:

1. A loss of a portion of the district's state aid due to a previous overpayment.
2. A rise in the assessed valuation which would mean an additional loss of state aid: It was projected that local monies collected would not offset the loss of state aid.
3. Spiraling inflation was creating an …

The Relationship Of Lateral Eye Movements To Field-Dependence-Independence And Verbal And Performance Skills, Linda J. Stennett-Mason

Masters Theses

Lateral eye movements and handedness as indexes of hemisphere asymmetry were compared to field-dependence-independence, as measured by Rod-and-Frame Test errors, and to Wechsler Verbal and Performance IQs. Consistent with previous research, the hypotheses predicted that persons with inconsistent lateral eye movements (ambilaterality) would have greater Rod-and-Frame errors (field-dependence) and lower Wechsler Verbal and Performance IQs.

Subjects were 41 male undergraduates who were grouped according to their lateral eye movements in response to 20 reflective questions consisting of ten verbal (left-hemisphere) and ten spatial (right-hemisphere) questions. The response scoring resulted in 12 subjects with 70% or more lateral eye movements to …

A Mechanism For Specifying Parallel Procedures, James Oliver Smith Jr.

Masters Theses

"This thesis presents a mechanism that will provide a semantic and syntactic environment for expressing parallel procedures. This mechanism will be referred to as the Parallel Machine. The parallelism of the Parallel Machine is accomplished through an arbitrary number of specialized computing elements that each implement a single command called a Simultaneous Command. Each Simultaneous Command is capable of determining the occasions for its action by observing conditions within the Parallel Machine. There is no restriction on the number of Simultaneous Commands that can be defined or be simultaneously active. Within a parallel procedure expressed as a set of Simultaneous …

A Metallurgical Evaluation Of The Mi Vida Prospect: A Mixed Copper Sulfide-Carbonate Ore Body, Sells, Pima County, Arizona, Kevin Michael Kenney

Masters Theses

"A copper-prospect in south-central Arizona has been evaluated on a metallurgical basis. Primary chalcocite and secondary covellite, plus the copper oxides malachite and brochantite, constitute the economic mineralization. The deposit outcrops as a steeply dipping (70°SW), intensely brecciated, copper-bearing quartz vein with discontinuous lenticular ore shoots.

Acid leaching techniques alone and in conjunction with froth flotation utilizing four copper oxide specific collectors were used to evaluate the amenability of this ore to processing. Direct acid leaching was examined and found to be ineffective. Removal of the chalcocite by froth flotation with xanthate was easy and gave better results to subsequent …

Molybdenum Stability In Coal Slags At 1400⁰C: Corrosion Properties For Mhd Electrode Applications., Kenton Brian Wright

Masters Theses

"Molten coal slag corrosion studies conducted on molybdenum at 1400°C used static and stirred slag experiments and electrical current experiments to parallel electrode conditions of slagging duct MHD generators. Crucibles containing molybdenum and slag were exposed to combustion-type gases in a tube furnace. Carbon monoxide-carbon dioxide gas mixtures controlled oxygen partial pressures at selected values between 10^-11 and 10^-3 atm. Metallograph and microprobe examination of polished sample sections defined corrosion characteristics.

At 1400°C, molybdenum metal is stable below 10^-9 atm oxygen pressure. Molybdenum dioxide is stable at higher pressure, but volatile molybdenum trioxides prevent formation of stable …

Retention In Salem Elementary Schools, Charles M. Raglin

Masters Theses

Social or chronological promotion has long been a practice of the public schools of the United States. The alternative, nonpromotion or retention, has in the opinion of most psychologists and sociologists led to emotional and sociological trauma for the child. Another and probably the most cogent objection, is many parents oppose nonpromotion and are unwilling to accept the social stigma of "flunking." Children's achievement is a status symbol which profoundly affects families in many communities.

The writer contends that unless parents are directly involved in the decision early in the nonpromotion year, retention will not culminate in satisfactory achievement. Cooperation …

Saul Bellow's Henderson The Rain King: A Fusion Of The Comic And The Serious, George William Russo

Masters Theses

Bellow's comic vision points to a compromise between the romantic notion that self-perfection is attainable and the pessimistic notion that man is ultimately impotent and thus destined to fail. Through Henderson, Bellow shows that although man does not--and ultimately cannot--completely free himself of somatic demands and limitations, he is nevertheless not defeated by them and thus not left a victim of emotionless observations.

Bellow draws upon four sources in Henderson's nature to create the humor in the novel and highlights Eugene Henderson as a comic hero by dramatizing that Henderson proves to be his own ironist. These sources can be …

Polar Opposites In Hermann Hesse's Novels, Karen Lea Nead

Masters Theses

The object of this thesis is to show how Hermann Hesse utilizes polar opposites and to show how the integration of conflicting forces works in the lives of the fictional characters in Demian, Steppenwolf, Narcissus and Goldmund, and The Glass Bead Game. These four novels not only are representative of the progression of the individual, but together, they are a consecutive representation of the artist's own search for a unified self. Influenced by psychologist Carl Jung's theories regarding the process of development, Hesse portrays the protagonists in constant search of the self. Some of the characters …

Recovery Of Lead From Lead Smelter Mattes, Cheng-Ping Chang

Masters Theses

"A by-product of lead smelting is a matte which consists mostly of lead and copper sulfides. Experiments were conducted to determine the feasibility of removing lead from molten matte by adding iron as a reducing agent. The effectiveness of iron at 1000 and 1100°C was a function of matte composition, but not of temperature except near iron saturation. The lead content of matte could be decreased to as low as 9.0 to 11.6 wt pct (2.3 to 3.0 at. pct) at 1000°C, depending on composition. The effect of oxygen in the matte on lead recovery from iron-saturated mattes was also …

Stress-Strain Properties Of Compacted Modified Memphis Loess, Danny Lloyd Kerns

Masters Theses

"A study was made of the stress-strain characteristics of compacted samples of a modified loessial soil obtained near Memphis, Tennessee. The study consisted of compacting samples at a constant water content and at unit weights of 92, 96 and 100 pounds per cubic foot (1470, 1540 and 1600 kg/m³). Triaxial tests were performed on unsaturated compacted specimens to obtain stress-strain-volume change data. These data were used to determine stress-dependent functions for tangent modulus and Poisson's ratio"--Abstract, page ii.

A Planning System For Research Management In A University Environment, Russell Lee Goldammer

Masters Theses

"The research project director at a college or university has few, if any, of the traditional management tools that are available for other forms of management, especially in performing the early, crucial stages of planning. This is particularly distressing since managing a program in this type of environment can be very difficult, due to bureaucratic red tape and interdepartmental concerns. The purpose here is to develop an aid for managers with these problems, for more effective research management in a university environment.

After developing a general model for a typical research project at a university, the Gasification Research On Wood …

Development Of Impervious Low Thermal Expansion Petalite Bodies, Suchinda Chotipanich

Masters Theses

"Impervious petalite bodies were formulated from petalite, lithium aluminosilicate frit and kaolin. Thermal expansion coefficients for selected bodies were less than 2 x 10⁻⁶ /°C(20 - 600 °C). Mineralogy and the reactions in systems containing petalite, lithium aluminosilicate frit and kaolin were observed. Silica-poor high quartz solid solution was found to be the reaction product formed from the reaction between frit and kaolin before conversion to ß-spodumene solid solution at higher temperatures. The crystallization of the ß-spodumene solid solution phases in this system did not occur at the same temperature resulting in variation in the size of the crystallites. The …

Functions Of Menace: A Comparison Of The Room And The Birthday Party, Lee R. Martin

Masters Theses

An atmosphere of menace surrounds the action of Harold Pinter's plays, The Room and The Birthday Party. Several critics seem to agree that the menace originates in the outer world and threatens to intrude upon the security of a room, where people attempt to hide. But the menace may also originate within the room--from the inner world and not the outer. The Room illustrates how a character deals with a menace that is within, while The Birthday Party deals with agents of menace from the outer world.

Rose Hudd, in The Room, is dissociated from the outer world …

From Selflessness To Selfishness: Various Types Of Deception In Four Of Twain's Novels, Kay L. Smith

Masters Theses

An interesting feature of Mark Twain's The Prince and the Pauper, The Adventures of Huckleberry Finn, A Connecticut Yankee in King Arthur's Court, and The Tragedy of Pudd'nhead Wilson is the use of disguise and deception. The basis of much of the novels' actions concerns people who, for varied reasons, set out to fool other people. Other individuals or groups of people are self-deceived.

Motivations for the deception vary. Some entail selfless concerns of protecting a loved one. Some illustrate desires to maintain one's own safety and well-being. Still others involve negative, base qualities such as greed, …

Fielding's Clergymen, Kathleen Marie Puhr

Masters Theses

Henry Fielding presented more clergymen in his fiction than any other major novelist except Trollope, and his non-fictional writings--notably articles in his journal, The Champion--also reflect his interest in the status of the clergy in eighteenth-century England. In his series of articles entitled “An Apology for the Clergy,” Fielding establishes the criteria by which he feels clergymen should be judged and lists the qualities of the “true” and “false” clergymen.

This study reveals that while Fielding in his non-fictional works clearly explains the traits of the true clergyman, his fiction does not contain a clergyman measuring up to his …

Fitzgerald's Use Of The Four Elements In The Great Gatsby, John Philip Hawkins

Masters Theses

A great deal has been written about the conscientious effort that went into the design of F. Scott Fitzgerald's popular novel, The Great Gatsby, with its various allusions and numerous symbols. A careful reading of this novel will unveil the author's preoccupation with numerous metaphysical images, particularly the four elements--air, earth, water, and fire--which are considered to be the essential components of all matter.

Fitzgerald uses the four elements in The Great Gatsby to coordinate mood and physical settings, to give dimension to the settings, and to bring characters into sharper focus. The novel employs four settings, each one …
