The Design Of A Six Specimen Tensile Fatigue Machine, Charles Mark Percival

Theses and Dissertations

Although metal fatigue has been recognized for many years and during that time many persons have tried to find the explanation for it, there is still not a complete theory concerning this phenomenon. Metal fatigue is one of the major problems the modem designer must face. If the design techniques are to progress as other technological advances are made, it is evident that it will involve a better understanding of metal fatigue.

An Ecological Study Of An Exclosure In The Mountain Brush Vegetation Of The Wasatch Mountains, Utah, Elray S. Nixon

Investigation Of The Platinum-Rich Portion Of The Platinum-Tantalum Phase Diagram, Bob Dean Browning

Theses and Dissertations

The Pt-Ta binary system was investigated at two isotherms;1000°C and 1500°C, and at eleven alloy compositions in the range of 50 to 100 atomic percent platinum. The alloys were examined by x-ray diffraction and metallography. Three intermetallic compounds, Pt₂Ta, Pt₃Ta, and Pt₄Ta were found to exist in this composition range. The Pt₄Ta intermetallic appeared only at the 1500°C isotherm. Platinum dissolved tantalum substitutionally to 90 atomic percent at 1500 °C and to approximately 80 atomic percent at 1000 °C.

Design Of An Air Stabilized Plasma Arc, William Robert Clarke

Theses and Dissertations

The plasma-arc generator (see figure 1, 2) has been used for several years as an invaluable ground test facility in which the gas stagnation properties of hypervelocity flight may be reproduced. The plasma is produced by shorting an electric arc between two electrodes; then directing a gas stream through the arc. The gas stream is thus heated to a ''temperature " of forty to fifty thousand degrees Farenheit. At this temperature the gas is in a state of partial ionization termed "plasma". The plasma stream is then constricted and directed by a nozzle into a test chamber and over the …

A Comparative Study Of The Axillary Sclerites In Coleoptera, Howard P. Shurtleff

Theses and Dissertations

The axillary sclerites of 69 species representing 52 families of the order Coleoptera were examined and illustrations prepared of most or them. A description is given for the typical axillary sclerites and the deviations in form from this pattern are discussed for the major groups of beetles. The phylogenetic relationships between some families, and other groups, are pointed out based on the morphology of the axillary sclerites. Phyletic groups in Adephaga are characterized by the axillary sclerites, but in the Polyphaga variations are too numerous and inconsistant to be useful in determining phyletic trends.

The Surficial Geology Of Southern Logan County, North Dakota, John W. Bonneville

Theses and Dissertations

Southern Logan County, North Dakota, was glaciated at least three different times during the Pleistocene epoch. Scattered patches of highly weathered iron-cemented drift found in the area of eroded Cretaceous bedrock in southwest-era Logan County are very possibly pre-Wisconsinan in age. Two younger drift sheets of Wisconsinan age cover the remaining portion of the county. One of these drifts, the Napoleon drift, is probably early Wisconsinan, and the other, the Burnstad-Streeter drift, is likely late Wisconsinan in age.

A great diversity in types of glacial topography and individual features is found in southern Logan County. Excellent examples of end moraine, …

A Textual Comparison Of The Isaiah Passages In The Book Of Mormon With The Same Passages In The St. Mark's Isaiah Scroll Of The Dead Sea Community, Wayne Ham

Theses and Dissertations

The Book of Mormon contains twenty-one chapters of the Book of Isaiah: two through fourteen, twenty-nine, and forty-eight through fifty-four. The language is primarily that of the King James Version with some variations. The King James Version itself has been translated from the Massoretic Hebrew Text. It is a fair assumption that the variations in the Book of Mormon represent an older, more accurate text than the Massoretic Text.

Textual critics are anxious to find ancient texts and versions of the scriptures in the hope that some of these texts may contain readings closer to the original than does the …

A Study Of The Attitudes Toward And Understandings Of Temple Marriage Of A Selected Group Of Seminary Students In The Alpine School District (Utah), Jerald Ray Johansen

Theses and Dissertations

The objective of most religious teachings and concepts is to change the student's attitude that desirable behavior may follow. The measurement of attitudes and the way people feel about certain religious concepts are, to an extent, determinative of their behavior. This realization has brought about a steady growth within the educational field of attitude and opinion measurement. It has also influenced religious educators to investigate this field in their efforts to get people to attain desirable religious goals.

The problem, investigated in the present research, was concerned with whether the youth of seminary age in the Church of Jesus Christ …
