A Swiss Patrician In New York City's Elite: Henri Casimir De Rham, 1785-1873, Robert H. Billigmeier

Swiss American Historical Society Newsletter

In the early nineteeth century, the Swiss who left for the New World faced the travail of a long journey over land to French ports or over land and by river vessels down the Rhine to ports of embarcation in Germany or the Netherlands. After the strenuous journey to the coast camme the hazards of the Atlantic crossing which still loomed ominously foreboding in the minds of emigrants desinted for North America. Some travellers, like Johannes and Anna Schweizer of Hemberg, St. Gallen, Brought more than the usual amount of baggage and sufferened the additional difficulties their encumbrances occasioned. The …

The Diatom Flora Of The Goshen Ponds And Wet Meadows, Larry L. St. Clair Aug 1975

The Diatom Flora Of The Goshen Ponds And Wet Meadows, Larry L. St. Clair

Theses and Dissertations

A taxonomic study of the diatoms of the Goshen ponds and adjacent wet meadows, Utah County, Utah, was conducted from April 1974 to March 1975. The diatom flora of these warm spring fed ponds consisted of thirty-five genera containing one hundred twenty-one species, twenty-eight varieties, and two forms. The flora was dominated primarily by the following genera: Achnanthes, Fragilaria, Synedra, Navicula, Cymbella, Terpsinoe, and Nitzschia. Nineteen plates with 150 illustrations accompany the text.


The Effect Of Altitude On Thyroid Function Of The Uinta Ground Squirrel (Citellus Armatus), Wendell Lee Wells Aug 1975

The Effect Of Altitude On Thyroid Function Of The Uinta Ground Squirrel (Citellus Armatus), Wendell Lee Wells

Theses and Dissertations

Thyroid uptake and distribution of 125I, concentrations of T4 and T3 in serum and thyroids and concentrations of TSH in serum and pituitaries were measured to determine thyroid function of Uinta Ground Squirrels (Citellus armatus) native to 5,400 and 9,000 feet elevations to evaluate alterations in the state of the thyroid due to increased altitude. Uptake of 125I was 60 percent lower by squirrels from 9,000 feet. Incorporation of 125I into T3 was greater at the higher elevation, but absolute thyroid T3 concentrations were similar at both elevations. No significant differences were found in serum T3 concentrations, but squirrels living …


The Effect Of Nitroalkanes On The Electrolytic Oxidation Of Tertiary Butyl Amine And Tertiary Amyl Amine, Karl Lloyd Bergen Aug 1975

The Effect Of Nitroalkanes On The Electrolytic Oxidation Of Tertiary Butyl Amine And Tertiary Amyl Amine, Karl Lloyd Bergen

Theses and Dissertations

The electrolyses of tert.-butyl and tert.-amyl amines were run with a voltage of approximately 3v., as measured across the cell, with and without the presence of 1-2% nitro-tert.-alkane. A graphite anode was used; the supporting electrolyte was NaClO4; the solvent was the reacting amine(s) with 10-20% water to solubilize the NaClO4. The products were azo compounds, azoxy compounds, 1,3-disubstituted ureas and traces of nitroso compounds. In the case of tert.-butyl amine di-tert.-butyl carbodiimide was also shown to be a product. The presence of nitro compounds increased the yields of azoxy and nitroso compounds and decreased the yields of azo compounds. …


The Effects Of Certain Steroids On The Growth Of Slime Mold, Physarum Polycephalum, Ching-Bun Paul Chen Aug 1975

The Effects Of Certain Steroids On The Growth Of Slime Mold, Physarum Polycephalum, Ching-Bun Paul Chen

Theses and Dissertations

The cortex of vertebrate adrenal glands secretes two major groups of hormones--glucocorticoids and mineralocorticoids. Glucocorticoids, which have an oxygen atom at carbon number 11, increase the rate of gluconeogenesis and increase the mobilization of lipids in mammals (Turner and Bagnara 1971). At the same time there is a decrease in protein synthesis. This latter effect may be homologous to a decrease in fibroblast growth in culture in the presence of certain corticosteroids (Ruhmann and Berliner 1965). The main function of mineralocorticoids, on the other hand, is to retain sodium ions. They have little or no gluconeogenic activity. Interestingly, however, these …


The Effect Of Recreational Uses On Vegetation And Soil In The Buffalo Campground, Targhee National Forest, Island Park, Idaho, Susan Daines Foster Aug 1975

The Effect Of Recreational Uses On Vegetation And Soil In The Buffalo Campground, Targhee National Forest, Island Park, Idaho, Susan Daines Foster

Theses and Dissertations

The effect of trampling on vegetation and soil, as a result of recreational pressure, was studied in the Buffalo campground of the Targhee National Forest, Idaho. Site deterioration was most evident in the forty-two year old site. The tree stand had matured, but there were few young trees and tree reproduction had been reduced to ten seedlings per acre for Pinus contorta. Only two shrub species were sampled with a combined population of eight individuals per acre. Most of the grass species had been seeded; forbs provided 20% of the ground cover, 13% was bare ground and 71% litter. The …


Bionomics Of Two Bark Beetles : Genus Chaetophloeus (Coleoptera : Scolytidae), John Wendell Aaron Aug 1975

Bionomics Of Two Bark Beetles : Genus Chaetophloeus (Coleoptera : Scolytidae), John Wendell Aaron

Theses and Dissertations

Shrubs are important as browse and cover for game animals and songbirds in the desert-shrub and chaparral plant communities in the Great Basin (Plummer, 1968). They also play a major role in soil binding and watershed maintenance (Colby and Weissert, 1975). Therefore, an understanding of the agents which affect the health and survival of the shrubs is important. Insects-have a great impact on the health and reproductive capacity of shrubs. Pollinators, defoliators, borers, etc. must be studied and known for proper management.

Ultrastructural Investigations Of The Host-Parasite Interface Of Pumpkin Cotyledons And The Fungus Sclerotinia Sclerotiorum, Mark Edward Richtsteig Aug 1975

Ultrastructural Investigations Of The Host-Parasite Interface Of Pumpkin Cotyledons And The Fungus Sclerotinia Sclerotiorum, Mark Edward Richtsteig

Theses and Dissertations

Pumkin seedlings (Cucurbita maxima) were inoculated with the fungus Sclerotinia sclerotiorum (Lib.) de Bary. Center regions of non-infected and infected cotyledons of various lengths were cut into 1 x 2 mm strips and processed for ultrastructural investigations. Complementary portions of opposing non-infected cotyledons were also processed as control tissue, and contained fewer storage products in cells than cotyledons of comparable size from non-infected plants. Young non-infected cells contained distinct lipid bodies, protein bodies and electron dense inlusions which were translocated out of older cells by abundant plasmodesmata. Initally, infected cells became plasmolyzed, followed by breakdown of the cytoplasm. Host cells …


Synthesis And Stereochemistry Of 2,6,10-Triazatricyclo [5.2.1.0⁴ ¹⁰] Decane Derivatives, Susan Elaine Foulger Aug 1975

Synthesis And Stereochemistry Of 2,6,10-Triazatricyclo [5.2.1.0⁴ ¹⁰] Decane Derivatives, Susan Elaine Foulger

Theses and Dissertations

The synthesis and stereochemical aspects of derivatives of the new ring system 2,6,10-triazatricyclo [5.2.1.04,10] decane are discussed. Sythesis of 2-nitro-2-methyl-1,3-disubstitutedaminopropanes, followed by reduction of these compounds to 2-amino-2-methyl-1,3-disubstituted aminopropanes afforded the necessary starting materials for a cyclization reaction similar to that resulting in already known 2,6-dioxa-10-azatricyclo [5.2.1.04,10] decanes. Reaction of the triamines with 2,5-hexanedione resulted in 2,6-disubstituted-1,4,7-trimethyl-2,6,10-triazatricyclo [5.2.1.04,10] decanes. The stereochemical aspects of this ring system are interesting from the standpoint of nitrogen inversion barriers on nitrogens 2 and 6. Existence of a high inversion barrier for these nitrogens in shown by isolation of different diastereomers of the tricycle. Methods …


The Effect Of Lead And Zinc On Selenium Poisoning In Mice, Cynthia Joy Call Aug 1975

The Effect Of Lead And Zinc On Selenium Poisoning In Mice, Cynthia Joy Call

Theses and Dissertations

Trace elements, because they are effective in catalytic amounts, must be held in delicate balance with each other as well as with the macronutrients of the diet. Disturbances of these balances result in deficiency and toxicity symptoms. Toxic doses of selenium, lead, and zinc, for example, are known to cause anemia (1, 2, 3, 4) and growth depression (5, 3) in experimental animals.

Macrocyclic Polyether Sulfide Syntheses :|Bthe Preparation Of Thia-Crown-6, 7, And 8 Compounds, Robert Askew Reeder

Theses and Dissertations

Macrocyclic polyether sulfides have been prepared by reacting an oligoethylene glycol dichloride with a dithiol in refluxing basic ethanol. The following new compounds were prepared: 1,5-dithia-(19- crown-6), 3-hydroxy-1,5-dithia-(19-crown-6), 1,4-dithia-(21-crown-7), 3-hydroxy-1,5-dithia-(22-crown-7), and 1,4-dithia-(24-crown-8). One other previously reported macrocyclic polyether sulfide was also prepared. The thesis includes a review of macrocyclic sulfides and other related compounds, the thermodynamics of interaction of several macrocyclic polyether sulfides with Ag^+, Hg^2+, and Pb^2+ ions, and a discussion of the structure of these materials.


Habitat Partitioning In A Community Of Passerine Birds, Robert C. Whitmore Aug 1975

Habitat Partitioning In A Community Of Passerine Birds, Robert C. Whitmore

Theses and Dissertations

Habitat partitioning was studied in a community of passerine birds in the Virgin River Valley of southwestern Utah. Ten habitat structure variables were measured for each of 24 species of passerine birds and several multivariate statistical techniques were used to determine the extent of habitat partitioning. Ordinations of species distributions along known environmental gradients were constructed using Principal Component Analysis and Stepwise Discriminant Analysis. Stepwise Discriminant Analysis was also used to determine which habitat variables were important in species separation. It was found that percent canopy cover was the most important variable. Two hundred seventy six pairs of species were …


Analysis Of Macroinvertebrate Samples From Ten Rocky Mountain Streams, Fred A. Mangum Aug 1975

Analysis Of Macroinvertebrate Samples From Ten Rocky Mountain Streams, Fred A. Mangum

Theses and Dissertations

This study was an attempt to evaluate the effects on ten Rocky Mountain streams from management activities on U.S. Forest Service lands. Macroinvertebrate and water chemistry data were collected. Data analysis methods included: three diversity indices, a numerical taxonomy system of multivariate statistical analysis, numbers and biomass per selected taxa, percent composition per order, and total numbers and biomass. None of the methods of analysis were found to be adequate if used alone, but by using a combination of dendograms, biomass, and numbers data in addition to the diversity indices (SCI and d) stream stress could be detected. Although organic …


Steady State Fluidics: The Static Matching Of Fluidic Amplifiers And Loads, Frank J. Redd Aug 1975

Steady State Fluidics: The Static Matching Of Fluidic Amplifiers And Loads, Frank J. Redd

Theses and Dissertations

"Fluidics" is the title applied to a relatively new technology which is concerned with the control of fluid power and the processing of information through the use of the fluid mechanical properties of the fluid medium itself. The absence of moving parts and the relatively low sensitivity to enviromental conditions suggest the probability that fluidic systems will prove to be faster and more reliable than the mechanically controlled (valves, diaphragms, springs, etc.) fluid systems which they are designed to replace.


Timpanogos Flora, Kelly W. Allred Aug 1975

Timpanogos Flora, Kelly W. Allred

Theses and Dissertations

A comprehensive floristic study of Mt. Timpanogos, Utah County, Utah, was undertaken. The Mt. Timpanogos area is a much used facility in recreation, biology, watershed development, livestock management, and education. It is also representative of a major segment of the overall flora of Utah. This study adds to the ever-increading knowledge of the flora of Utah, and provides a means of identifying the flora of this region, which is basic to any future management.
