Metastatic Patterns And Functional Disability In Disseminated Breast Carcinoma, Stephen Adam Gudas

Theses and Dissertations

Thirty female outpatients with metastatic breast carcinoma were evaluated using two operational models constructed for the purpose of assessing and assigning a quantitative score for (A) extent of metastatic disease and (B) level of functional disability. These patients were drawn from the population of patients with disseminated breast carcinoma attending the medical oncology clinics at the Medical College of Virginia Tumor Clinics for a 49 day period in 1975. The data from this patient sample were used to test several hypotheses.

Each patient underwent an initial screening procedure designed to clearly identify those patients with disseminated disease. This was followed …

Quaternary Geology Of The Southern Part Of The Grand Forks And Bemidji Quadrangles, Donald K. Sackreiter

Theses and Dissertations

Northwestern Minnesota is an area at the southwestern edge of the Canadian Shield that is mantled by thick Pleistocene sediment. The Pleistocene material included a variety of glacial, shoreline, offshore, fluvial, and eolian sediment.

The lithology of the glacial sediment reflects the rock and sediment over which the depositing glacier flowed. Glaciers that advanced from the northeast (Canadian Shield) deposited sandy, granitic-rich material. Glaciers that advanced from the north· (Manitoba Lowland) deposited loamy, calcareous-rich material. Glaciers that advanced from the northwest (eastern North Dakota and southwestern Manitobal deposited clayey, shale-ridt material. A variety of fluvial and lacustrine sediments are typically …

Stratigraphy Of The Upper Part Of The Fort Union Group In Southwestern Mclean County, North Dakota, Leroy A. Hemish

Theses and Dissertations

Southwestern McLean County is an area characterized by glacial topography and glacially-modified bedrock topography, with limited exposures of bedrock. Outcropping bedrock formations include the Cannonball, Tongue River, and Sentinel Butte Formations, all in the Fort Union Group of Paleocene age.

The Cannonball Formation crops out only in the southeastern part of the area studied (at Washburn), where 18 feet of laminated, gray-brown sandy mudstone is exposed. A yellow-brown, cross-bedded sand unit directly overlies the mudstone. I have tentatively selected the base of this sand unit, which is present in the subsurface throughout southwestern McLean County and reaches thicknesses of more …

Glacial Stratigraphy Of Northeastern North Dakota, Howard Hobbs

Theses and Dissertations

Seven lithostratigraphic units (formations} composed dominantly of glacial sediment have been recognized in northeastern North Dakota. Three formations, the Falconer Formation (Harris and others, 1974}, the Dahlen, and Gardar Formations (Salomon, 1975). Have been previously recognized. Four formations, the Hansboro, Vang, Tiber and Cando Formations are newly recognized. Uncorrelated units of glacial sediment are described but not named. The formations are differentiated and correlated primarily by the proportion of crystalline (igneous and metamorphic rock fragments), carbonate, and shale grains in the coarse sand fraction (1 to 2 mm) of the glacial sediment. The proportion of shale grains was. Found to …

Petrography Of Precambrian Iron Formation, Pembina County, North Dakota, Ronald E. Richardson

Theses and Dissertations

In October of 1964 the Topographic Branch of the United States Geological Survey reported difficulties in using magnetic compasses while mapping in the areas of Akra and Hensel, Pembina County, North Dakota. University of North Dakota geologists located anomalies of 67,500 gammas 1.6 lon east of Akra and 71,500 gammas 4 km east of Hensel, the normal magnetic field in this area being about 60,000 gammas. The rock bodies producing the magnetic anomalies were drilled and examination of diamond drill core showed them to consist of oxide and silicate facies iron formation interlayered with quartz-biotite schist of Precambrian age. The …

Stratigraphy Of Offshore Sediment Of Lake Agassiz, North Dakota, Michael B. Arndt

Theses and Dissertations

Lake Agassiz occupied the Red River Valley between about 13,800 and 9,000 years ago. The Late Wisconsinan ice sheet that covered the Red River Valley retreated far enough to expose the drainage divide in northern South Dakota and south-central Minnesota sometime after 14,000 B.P. and meltwater ponded behind this divide in Richland County. Before 13,800 the ice readvanced over this area and then retreated again. As the ice margin retreated northward, deposition of the Argusville and Wylie Formations took place. Sometime before 12,800 the ice advanced again into the Red River Valley as far as Traill County; the terminus of …

The Effect Of Success And Failure Experiences On Self Concept In Retarded Children, Candace Joan Varvil

Theses and Dissertations

The object of this study was to examine the relationship, if any, between success and failure experiences and self-concept in retarded children. The Piers-Harris Children's Self-Concept Scale was administered to 30 institutionalized mentally retarded children at the Grafton State School. Following the administration of the pretest, the subjects were divided into three groups, two experimental and one control. Each group was further subdivided into a high and a low self-concept group on the basis of pretest performance. The groups were generally comparable with respect to chronological age and sex. Experimental group A was exposed to a success experience, experimental group …

The Relationship Between Attitudes Toward Women's Roles And Field Dependence-Independence In College Students, Patricia A. Torness

Theses and Dissertations

One rather consistent finding from studies involving field dependence-independence is that males are more field independent, more articulated in their approach to certain perceptual tasks, than females. It appears that socialization factors and sex-role identification relate to the development of field dependence or field independence. If society plays a part in the development of individual differences in field dependency, a change in society such as the present movement toward greater equality in sex roles could possibly influence sex differences in field dependency. The present study attempts to assess the effect of attitudes favoring traditional roles for women vs. more liberal …

Solids-Liquids Separation In Coal Solution Technology, Ferdosh D. Nankani

Theses and Dissertations

An alternate method to the conventional filtration for separation of mineral matter from dissolved lignite was investigated. Separation was accomplished by the introduction of an organic diluent mixed with the solid-liquid product from hydrogenation-solubilization of lignite and decanted at elevated temperatures and pressures. This method gave separation as high as 88 percent recovery of solvent refined lignite (SRL). The SRL contained ash as low as 0.70 percent versus 0.1 to 0.6 percent ash obtained by filtration methods.

The technique investigated is analogous to methods used in the deasphalting of petroleum residuum employed in the petroleum industry. The introduction of the …

The Effects Of Highway Construction On The Fish Populations In The Weber River Near Henefer, Summit County, Utah, Edward James Peters

Theses and Dissertations

Alterations of streams to facilitate highway construction and consumptive water use has become a fisheries management problem. To evaluate the effects of channeling concomitant to construction of Interstate 80 N. near Henefer, Utah, altered and unaltered sections of the Weber River were compared on the basis of fishes censused, population estimates and ordinations. Species compositions in particular areas were influenced by local rheologic conditions. Changes in species composition between samplings at a particular area were caused by fish movements. Data from altered sections, rehabilitated with deflectors and checkdams, were not noticeably different than data from unaltered areas. However, fish movements …

The Purification And Characterization Of Methylmalonyl Coa Mutase From Bovine Brain, Damon Martin

Theses and Dissertations

Methylmalonyl CoA mutase has been purified over 2300-fold from bovine brain using fractional precipitation, ion exchange resins, and gel filtration procedures. The crude extract had an equal mixture of mutase in the halo- and apoenzyme form. After the final purification step the ratio had changed to 86% holo-enzyme and 14% apoenzyme. The mutase enzyme had a pH optimum of 7. 0 in Tris-HCI buffer. The Km values for L-methylmalonyl CoA and succinyl CoA were 7.7 x 10^-4 M and 1.8 x 10^-4 M respectively. The equiIibrium constant in the direction of succinyl CoA formation was 19. Inhibition with N-ethylmalei-mide was …

The Spatial Distribution Of The Nests Of The Black-Crowned Night Heron (Nycticorax Nycticorax) And The Snowy Egret (Leucophoyx Thula) In Central Utah, Randall S. Isham

Theses and Dissertations

Nests of the Black-crowned Night Heron and the Snowy Egret were examined in five central Utah colonies in 1973 to determine the spatial distribution within the colony. Nest locations of the 1085 nests of the two species were plotted to the nearest foot with an alidade and plane table. Tests of randomness, clump size, association, segregation, and T distribution were utilized. No differences between species were noted for the distance to the nearest and the next nearest nest. The Night Heron nested closer to other Night Herons and more often than did the Snowy Egret which non-significantly selected either species …
