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

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

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

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

Self-assembly and charge transport properties of a benzobisthiazole end-capped with dihexylthienothiophene units

The synthesis of a new conjugated material is reported; BDHTT–BBT features a central electron-deficient benzobisthiazole capped with two 3,6-dihexyl-thieno[3,2-b]thiophenes. Cyclic voltammetry was used to determine the HOMO (−5.7 eV) and LUMO (−2.9 eV) levels. The solid-state properties of the compound were investigated by X-ray diffraction on single-crystal and thin-film samples. OFETs were constructed with vacuum deposited films of BDHTT–BBT. The films displayed phase transitions over a range of temperatures and the morphology of the films affected the charge transport properties of the films. The maximum hole mobility observed from bottom-contact, top-gate devices was 3 × 10−3 cm2 V−1 s−1, with an on/off ratio of 104–105 and a threshold voltage of −42 V. The morphological and self-assembly characteristics versus electronic properties are discussed for future improvement of OFET devices
