The Nature Of Swiss Drawings, Dr. Francois Bucher

Swiss American Historical Society Newsletter

The exhibition of Swiss drawings which travels from Washington, D.C. (October 7 -29, 1967) to New York (Pierpont Morgan Library: November 15, 1967 - January 2, 1968), San Francisco (M.H. de young Memorial Museum: January 14 - February 12, 1968) and Chicago (Art Institute: February 24 - March 26, 1968) 1) poses two problems:

1) Why did drawing and generally graphic expression play such an important role in the work of Swiss artists from Urs Graf to Giacometti?

2) What was the role of Swiss art within the European creative community, in other words, what is its qualitative position?

An Exhibition Of Swiss Drawings Shown In The U.S., Dr. Lukas Burckhardt

Very High Pressure Effects Upon The Epr Spectrum Of Ruby, H. Mark Nelson, D. B. Larson, J. H. Gardner

Faculty Publications

The variation in the electron paramagnetic resonance (EPR) spectrum of ruby as a function of pressure has been observed to beyond 70 kbar for a magnetic field orientation parallel to the crystalline c axis. The data can be interpreted in terms of the usual spin Hamiltonian, where the spectroscopic splitting factor g|| has the same value as at ambient pressures, but where the zero-field splitting deltaincreases in a linear fashion from 0.38 to 0.43 cm. The experimental apparatus has been described previously, although important improvements in the pressure seal and in the pressure calibration have been made and are described …

Theses and Dissertations

Eriogonum corymbosum Benth. in DC is a low-growing perennial shrub which is found in many cold temperate desert shrub regions of Colorado, Utah, and Nevada.. It is a species which grows on numerous soil types and/or geological formations. Specific objectives of the investigation were to study and describe certain community relationships of ten different plant communities where E. corymbosum was found. Each community was sampled to determine the amount of ground cover, percent composition, frequency, and density of each participating species. Physical site factors viz. soil texture, total soluble salts, pH, cation exchange capacity, and amount of calcium, magnesium, potassium, …

Changes In Hemoglobin During Metamorphosis Of The Salamander, Harvey Dee Mecham

Theses and Dissertations

Analysis of hemogobins were conducted on animals of the species Ambystoma tigrinum. Separation of hemoglobin types was performed with a Carboxy-methyl-cellulose column (6 X 50 mm.) and pH gradient (pH 6 thru 8) of .01 M phosphate buffer. The hemoglobins in the effluent were detected and analysed with a micro-flow cell in a Beck-man DB-G spectrophotometer attached to a Photovolt Varicord 43 recorder. Two major components of hemoglobin were observed: larval and adult. These two components varied in concentration with the stage of development of the individual. In addition, it was noted that minor peaks ansd shoulders appeared on each …

Hematological Variation Associated With Altitude, Season, Sexual Activity And Body In The Uinta Ground Squirrel, Ralph Theodore Kinchloe

Theses and Dissertations

Hematological comparisons were made on the Uinta ground squirrel (Citellus armatus) trapped at different altitudes and during vari ou s stages of seasonal activity in 1965 and 1966. Hematological variation due to sex, sexual activity and body weight were also analyzed. Ground squirrels were secured from the Mt. Timpanogos area near Provo, Utah County, Utah. Erythrocyte count, hematocrit, total blood hemoglobin, mean erythrocyte volume, mean erythrocyte hemoglobin and reticulocyte counts were measured using standard procedures; banding patterns of hemoglobin and serum proteins wer e determined by means of electrophoresis with polyacetate strips.

An Electrophoretic And Chromatographic Study Of The Hemoglobin From Adult And Fetal Pigs, Donald William Green

Theses and Dissertations

Hemoglobin, from the erythrocytes of adult and fetal pigs, was isolated and analyzed by carboxymethylcellulose column chromatography and electrophoresis on polyacetate. These techniques demonstrate the existence of four fetal components (F0, F1A, F1B, F1C) and two adult components (A0, A1) based on their elution pH values and electrophoretic mobilities. The shift from-fetal to adult forms is initiated sometime between eight weeks after birth and one year. The change is not completed until sometime after one year and the major fetal forms (F0, F1A) maintain a 15% level in a mature adult. This report is in contrast with the results of …

Theses and Dissertations

The study of frictional drag force reduction has been the subject of much research for many years. One of the significant developments in the field of frictional drag force reduction has been the discovery of the effectiveness of dilute polymer solutions in reducing drag. By using dilute high-polymer solutions frictional drag forces in pipe flow have been reduced by as much as 70 per cent.

An Ecological Study Of The Algae And Mosses Of Cascade Springs, Wasatch County, Utah, Deanna Lynn Mccoard

Theses and Dissertations

An ecological study was conducted at Cascade Springs, Wasatch county, Utah from August 1965, to June 1967. The algae and aquatic moss species were determined and ecological information about these organisms was obtained. Physical data were also collected: bicarbonates, carbonates, free carbon dioxide, hydroxides, oxygen, pH, and temperature. The physical environment of the water was found to be very constant. Tests taken at the different study sites were consistently similar, not only during each day, but all year around. No great variation of any kind was found in the water. In contrast to the water environment, the topography of the …

Secondary Reactions And Partial Rate Factors In The Sulfonation Of Chlorobenzene And Toluene, Ernest Arthur Brown

Theses and Dissertations

The sulfonation of chlorobenzene, chlorobenzene-benzene, and toluene-benzene mixtures by sulfur trioxide in liquid sulfur dioxide at -12.5° C. was studied to obtain isomer distribution and relative rate data. The isomer distribution for the reaction on chlorobenzene was determined by an isotope dillution technique. Relative rate experiments were conducted by sulfonating C14 labeled benzene in competition with nonradioactive chlorobenzene and toluene and the count rate of the products was used to determine product composition. Ultraviolet spectrophotometry was also used to investigate variations in isomer distributions as a function of sulfur trioxide concentration. The apparent relative rates of sulfonation (kX/kB) as calculated …

Predation Of Leptothrips Mali (Fitch) On Mites In Central Utah Orchards, James G. Brooks

Theses and Dissertations

Predation by thrips was referred to as early as 1882 when Pergande discussed their habits. Later, Plank (1936) found Leptothrips mali (Fitch) to be predaceous on lepidopterous eggs, and Sharp (1938) cited it as a being a predator of the pecan nut caseborer, Acrobasis caryae Grote. Bailey (1939) stated that the six-spotted thrip, Scolothrips sexmaculatus (Pergande), is predaceous on Tetranychus telarius (L.), Tetranychus pacificus McG., Bryobia praetiosa Koch, Paratetranychus citri McG., Paratetranychus pilosus (C & F.), Paratetranychus indicus Hirst, Paratetranychus yothersi (McG.), Paratetranychus ilicis (McG.), and Phyllocoptes oleivorus Aschm. and in 1943 Bailey and Keifer noted that L. mali fed …

A Study Of Thermal Responses Of A Body Of Complex Geometry To A Moving Heat Source, J. Norman Smith

Theses and Dissertations

The effect of the fusion welding process upon the metals being welded is a matter of great interest and has been the subject of much investigation, both theoretical and experimental. The properties of metals are determined by the structure of their crystals (within limits for any given metal), and the crystalline structure is determined by heating and cooling rates. Thus the knowledge of temperatures, and heating and cooling rates, becomes the key to understanding these effects of heating. Since the greatest part of fusion welding is done using a gas torch or an electric arc, the necessary theoretical study is …

The Status Of The Common Crow Corvus Brachyrhynchos Brehm In The Great Basin, Gerald Low Richards

Theses and Dissertations

Due to a lack of taxonomic and distributional information concerning the Common Crow Corvus brachryhynchos Brehm inhabiting the Great Basin of North America, Johnston (1961) in one of the most recent revisions on crows, was unable to include this area in his work. Between 1965 and 1967, field trips were taken throughout the Great Basin to secure specims, and to determine to what extent the area was being utilized by crows. Ecological information such as habitat prference, nesting behavior, and interactions with other species was collected where possible. Forty-eight birds were collected from the Great Basin. From a comparison of …

Investigation Of Nitrogen Fixation By Three Species Of Lichen, Dortha Maloy Robinson

Theses and Dissertations

One species of lichen from each of three different families (Collema wyomingensis , Caloplaca elegans (Link)T. Fries, and Parmelia molliuscula Ach.) was studied to determine whether or not these lichens can fix atmospheric nitrogen. Samples of these three lichens were collected in the early spring of 1967. Samples of each species were placed in 20-ml glass tubes which contained 5 ml of glass wool saturated with 0.5 M nitrogen-free Hoaglands nutrient solution. These tubes were sealed by heat onto a gas manifold system and evacuated. An N15- enriched atmosphere (22 atoms % N15) was introduced into the tubes from the …
