Metasomatism between amphibolite and metaultramafic rocks during upper amphibolite facies metamorphism, Tobacco Root Mountains, southwest Montana

The purpose of this study is to characterize the metasomatism that has taken place as a result of the chemical incompatibility between mafic and metaultramafic bulk compositions during high-grade regional metamorphism in the Tobacco Root Mountains, southwest Montana. Metasomatism of these rocks took place by both diffusionand infiltration-dominated processes. The result of these processes are characterized mineralogically and geochemically in the rocks

A Day in the Life of a Supercomputer

We are developing an interactive dashboard for visualizing the statistics of how users interact with nodes of a supercomputer. The intended purpose of the dashboard is to periodically provide with the overview of the load and bandwidth utilization of the nodes of a large supercomputer and details of each node and job as selected by the user. The dashboard will be interactive which will enable users to zoom in on interesting parts of the visualizations to investigate in details

Retrovirus Mediated Gene Expression in Haematopoietic Cells

The expression of retroviral vectors in cell lines and primary cells was investigated, with emphasis on autocrine stimulation of haematopoietic cells by GM-CSF. In this study, two distinct retroviral vectors were used which allowed a dual approach to the investigation of expression of exogenous sequences in haematopoietic cells. Retroviral expression of GM-CSF in the growth factor dependent FDCP1 cell line resulted in factor independent colony growth, the frequency of which was related to the vector used. The characterisation of cell lines derived from viral infection of FDCP1 cells revealed that these cells required the concentration of self produced growth factor to attain a critical level before colony development occured. As a result of virus infection, FDCP1 cells which express the retrovirally encoded GM-CSF have a proliferative advantage over the parental cell line. Finally, a number of variables which might influence the success of retroviral infection of primary murine bone marrow cells were investigated. Initial results suggest that bone marrow cells can be infected with retroviral constructs containing the neomycin gene, the efficiency of which may be related to the origin of the vector. Thus, this study demonstrates the feasability of using retrovirus vectors to express exogenous sequences in haematopoietic cells. It also provides a system which can be used to evaluate the efficiency with which new vectors will express genes in primary haematopoietic cells

Sacrifice in the Eucharist in the texts of the fathers from the New Testament to the council of Chalcedon

This thesis examines the evidence for the notion of Eucharistic Sacrifice which is found in the original texts of all the principal Fathers and ecclesiastical authors of the Early Church. The period covered is from the time of the writing of the New Testament to the Council of Chalcedon in 451 A.D. Each of the principal Fathers is examined in historical order, as far as this is possible, except when there is another link between them such as their city of origin. Apart from a few exceptions, the texts are presented in their Greek or Latin original in the footnotes, but an English translation is supplied for every case in the main text of the thesis. The aim of the thesis is not to provide an exhaustive analysis of the above data, but to present them in an orderly way and to make initial exploratory comments on the texts themselves and of the work of various scholars. The final conclusion resulting from this exercise is that, although there is indisputable evidence that the notion of Eucharistic sacrifice was widely upheld by Patristic authors, its actual content varied from author to author and presents a richness which it is not easy to classify

INCIDENCE AND SIGNIFICANCE OF GIARDIA LAMBLIA (LAMBL ) IN TEXAS BEAVER POPULATIONS

The Giardia lamblia (Lambl) protozoan is not a recently discovered parasite. It was. in fact, one of the first organisms viewed and described by Antony van Leeuwenhoek (1681) as he designed the first usable microscope. Leeuwenhoek found this organism in a sample of his own diarrhetic stool and thus he constitutes the first confirmed case of human giardiasis. His finding represents proof of glardiasis’ close association with man for many years. Leeuwenhoek’s discovery of the giardial trophozoite was not elaborated on for some 178 years, however, as it was not until 1859 that Wilhelm D. Lambl systematically described the organism as being a distinct genus of protozoan parasite (Kudo 1966). Unfortunately Lambl made little mention of guardias\u27 medical significance and the giardial protozoan was not accurately recognized as a major health concern until late in the twentieth century

On groups with few subgroups not in the Chermak-Delgado lattice

We investigate the question of how many subgroups of a finite group are not in its Chermak-Delgado lattice. The Chermak-Delgado lattice for a finite group is a self-dual lattice of subgroups with many intriguing properties. Fasol\u{a} and T\u{a}rn\u{a}uceanu asked how many subgroups are not in the Chermak-Delgado lattice and classified all groups with two or less subgroups not in the Chermak-Delgado lattice. We extend their work by classifying all groups with less than five subgroups not in the Chermak-Delgado lattice. In addition, we show that a group with less than five subgroups not in the Chermak--Delgado lattice is nilpotent. In this vein we also show that the only non-nilpotent group with five or fewer subgroups in the Chermak-Delgado lattice is S_3

The Cuties Controversy: Prefiguration, ‘Sexualisation’, and the New Conspiracism

In this article, we draw on Martin Barker’s extensive body of work on film audiences and controversial media to explore the media furore around Maïmouna Doucouré’s Cuties(2020). When streamed on Netflix, several conservative groupings, including US Republican politicians, right-wing news outlets and Christian bloggers, led an intensely moralising campaign, largely shaped by outrage at Cuties’ representation of pre-adolescent girlhood. Deploying Barker’s techniques of examination of the implicit assumptions and ‘evidence’ that underpin responses to controversial media, our analysis draws out the working ‘figures of the audience’ to tell the story of the Cuties controversy. In particular, we highlight the different ways that arguments and debates about the film turned on these imagined and imaginary audience figurations that were deployed in the service of specific ideological positions. The article is comprised of four sections. It begins by exploring how Cuties became a cause célèbre before the film was even released, with discourses of ‘pornography’ and ‘paedophilia’ initially being established and structured through criticism of prefigurative materials rather than interpretations of the film itself. The two sections that follow examine claims made by Republican politicians and right-wing commentators about Cuties’ alleged potential to ‘sexualise’ young girls and to normalise or even instigate paedophilia. We place these ideologically-charged arguments around childhood protection into historical context, locating the emotional and rhetorical core of the controversy in ‘common-sense’ beliefs and ‘figures of the child’ that emerged in the nineteenth century and were developed further in the latter half of the twentieth century; beliefs that continue to dominate debates about girlhood sexualities and the perils they face today. The final section then explores the ways in which opposition to Cuties overlapped with conspiracy theories like those articulated by QAnon, placing the discourse in the context of what Muirhead and Rosenblum (2019) term ‘the new conspiracism’. Ultimately, we use the controversy to draw attention to the propagandising activities of political entrepreneurs, who were not simply reacting to a film they disliked but were instead seizing upon Cuties as a way of furthering their own (conservative) ideological agenda

Iron absorption and transport mechanisms as related to genetic susceptibility to cotton fur in mink

The "cotton fur" (CF) condition in mink has been shown through investigations at Oregon State University to have three basic causes, viz.: 1) Feeding diets of fish comprising certain species of the cod family, including: Pacific hake, Atlantic whiting and Alaskan pollock; 2) Inclusion of rancid fats in the diet; and 3) Genetic susceptibility of particular strains. This thesis investigates further the cause of CF as it relates to the third factor. Experiments were conducted in two areas and involved, first, a study of iron absorption using ⁵⁹Fe as a tracer in an attempt to determine if genetically susceptible, CF mink are able to absorb adequate dietary iron in a normal manner, and secondly, a study of the iron transport system by electrophoretic separation of the iron carrying proteins (transferring) to determine whether the CF mink differs from normal animals. Iron balance trials conducted at the Oregon State University Radiation Center were designed to investigate possible differences in gastro-intestinal absorption of ferrous iron between mink with an inherent proclivity to CF and normal animals. General methods for these trials followed those used by Bailey (1967). After a single dose of ⁵⁹ferrous sulfate was administered via stomach tube, total urine and fecal samples were collected for a period of seven days. Each sample was weighed, subsampled when necessary and counted to a standard error of one percent with an auto-gamma, deep-well, solid scintillation counter. Three milliliter blood samples were withdrawn from the unanesthetized mink by cardiac puncture periodically after isotope administration and mixed with an anticoagulant. Radioactivity of the whole blood was measured by counting a weighed one milliliter sample. From the remaining whole blood the hematocrit level was determined and the plasma thus separated, was weighed and radioactivity measured. Radioactivity of erythrocytes was calculated from these data. Technical problems encountered in the first two iron absorption trials indicated that presence of food in the gastro-intestinal tract prior to stomach tubing increased absorption possibly by acting to slow passage of the administered isotope. The presence of thiaminase in the fish component of the diet complicated the second trial and injections of thiamine were administered for the final trial. Although absorption was minimal it was concluded that under the conditions of these experiments the anemic CF mink absorbs iron equally as well as its normal counterparts. ⁵⁹Fe absorption followed the pattern expected of normal animals. To establish more definite conclusions about the absorption and metabolism of iron by the CF as compared to the normal mink would require subsequent trials. It was theorized that polymorphism of blood serum transferrins could conceivably account for the iron deficiency anemia observed in CF animals; therefore, the second phase of investigation of this abnormality involved electrophoretic study of these proteins. The disc electrophoresis apparatus and procedures used were patterned from those suggested by Davis (1964) for determining serum types in humans. A polyacrylamide-gel column, formed in a glass tube was composed of three layers: i.e. (1) a large-pore gel containing the serum sample in which electrophoretic concentration of the sample proteins was initiated; (2) a large-pore (spacer) gel in which electrophoretic concentration of the sample proteins was completed; and (3) a small-pore gel in which electrophoretic separation took place. Blood samples were collected by cardiac puncture as before and centrifuged to separate the serum. Three micro-liters of serum were placed in each column of the disc electrophoresis apparatus. A complete serum sample and a sample containing only the transferrin protein fraction prepared by following a precipitation technique described by Sutton and Karp (1965) were analyzed for anemic animals of the CF strain; normal mink of the Cr strain; and normal individuals from an unrelated strain. Proteins of the complete serum were stained with amido schwarz dye and compared visually with the corresponding precipitated serum sample from the same animal. Visual examination of complete, mink serum proteins revealed as many as 10 to 14 dark staining bands of varying thickness and intensities. The transferrins of the precipitated, serum, gel sample appeared as two, closely aligned bands usually corresponding to a single, heavy, dark band in the complete serum sample. Heavy concentration of protein in some cases apparently obscured the two bands. Polymorphism of serum transferrins in mink was not revealed in this study. Visual examination of gel samples indicated that the iron-transport proteins of CF mink were like those of the normal animal under the conditions imposed. Results did not conclusively indicate that such variants of protein do not exist, but it was concluded that any effect would be slight and would probably not be responsible for the CF condition in mink
