41	Land Grabbers, Toadstool Worshippers, and the Sagebrush Rebellion in Utah, 1979-1981 Rogers, Jedediah S. 15 July 2005 (has links) (PDF) In 1979, a handful of Nevada state officials sparked a movement to transfer the large unappropriated domain to the western states. For two years what became known as the Sagebrush Rebellion swept across the American West like brushfire, engaging westerners of all stripes in a heated dispute over the question of the public lands. In Utah, as elsewhere in the West, public officials, rural ranchers, miners, developers, academics, environmentalists, and concerned citizens joined the debate and staked sides. This episode underscored western relationships between people and nature and featured contests over competing ideologies in the West. But it probably did more harm than good in solving the problems of the West and even further polarized westerners against themselves. After just two years in the limelight, the Sagebrush Rebellion unspectacularly faded into public memory, partly as a result of environmental opposition but mostly because Ronald Reagan's administration steered public land policy in a new direction. Interior Secretary James Watt took steps to appease disgruntled westerners by loosening federal regulations on the public lands, but he opposed any efforts for a large-scale transfer. Thus the Sagebrush Rebellion ultimately failed; but still today the sentiment and conflicts that propelled it persist, continuing to color the panorama that is the American West.

42	Shifting, Linking and Framing : The Case for Technology as a Coherence-Making Textual Device in Literary Realism Brundell, Ruben January 2024 (has links) Literary realism, that is, texts that seek to represent the actual in literature while achieving a sense of verisimilitude, have historically been analyzed and defined by a number of critics. These critics have, with differing approaches, attempted to make comprehensible what it is that constitutes the realist text. In their process of doing so, many have dismantled this specific category of text and isolated its distinguishing components. This study has sought to challenge and elaborate on three of the most influential, scholarly voices that have articulated such ideas about the realist text: Ian Watt, Eric Auerbach and Roland Barthes. The purpose has been to add to this field of knowledge by increasing our understanding of what it is that constitutes literary realism. This has been done by analyzing three realist works that have been previously examined by these critics, and then, by studying two further realist works, more recent in time. These works are, in the order that they have been approached and analyzed: Daniel Defoe’s A Journal of the Plague Year (Published in 1722), Gustave Flaubert’s A Simple Heart (Published in 1877), Virginia Woolf’s Mrs. Dalloway (Published in 1925), Melina Marchetta’s Jellicoe Road (Published in 2006) and Gabrielle Zevin’s Tomorrow, and Tomorrow, and Tomorrow (Published in 2022). As a result, the study has found that technology is a recurring textual element that functions as a coherence-making narrative device in these realist texts, and as a consequence, has laid bare a blind spot in these above-mentioned critics’ definitions of literary realism. Thus, the study suggests that technology should be understood as a distinguishing element in the literary text. The selection of works has, in turn, allowed for the study to both compare and contrast these texts, and to trace the effect that the technological development in the reality preceding the literary text can be said to have on these texts themselves. Here, the study has found that new technologies in the reality preceding the text often occur as new coherence-making textual devices in these literary works, and thus, that the technological development in the actual affects the realist text itself.

Essas situações estão sendo continuamente estudadas, tendo em vista que podem causar problemas de qualidade de tensão e reparos em reguladores de tensão. O problema da sobretensão pode ser causado por uma injeção significativa de potência ativa da geração FV à rede. Paralelamente, as variações rápidas e significativas na potência ativa injetada pelo gerador FV, associadas com os transitórios de nuvens, podem resultar no aumento excessivo de comutações de tape no regulador de tensão, que podem acabar diminuindo a vida útil e aumentar a quantidade de manutenções realizadas nestes equipamentos. Neste contexto, surgiram as funções de controle Volt-Watt e Volt-Var prensentes nos inversores FV inteligentes, que foram adicionadas em estudos recentes para mitigar as sobretensões. Este trabalho mostra como as funções de controle Volt-Watt e Volt-Var mitigam os problemas de sobretensão e regulação de tensão em redes de distribuição com presença de geradores FV. Simulações de fluxo de potência de séries temporais em alimentadores simples de BT e MT com presença da geração FV foram realizadas em cenários de alta e baixa variabilidade solar. / This dissertation addresses some of the major operational problems faced by distribution system operators due to the high integration of photovoltaic (PV) generators, such as overvoltages and excessive tap counts in step voltage regulators (SVR). These situations are continually being studied, since they can cause voltage quality problems and damage in SVRs. The overvoltage problem can be caused by a significant injection of active power from the PV generation to the network. Moreover, the rapid and significant variations in PV generator active power associated with cloud transients result in an increase of voltage regulator tap counts, which can affect the useful life of device. In this context, the smart inverters Volt-Watt and Volt-Var control functions have been added in recent studies to mitigate the overvoltages. This work shows how Volt-Watt and Volt-Var control functions mitigate the overvoltage and voltage regulation problems in distribution networks with PV generation. Time series power flow simulations on LV and MV single feeders with PV solar plant have been performed in high and low solar variability scenarios.

46	The lesser names : the teachers of the Edinburgh Mathematical Society and other aspects of Scottish mathematics, 1867–1946 Hartveit, Marit January 2011 (has links) The Edinburgh Mathematical Society started out in 1883 as a society with a large proportion of teachers. Today, the member base is mainly academical and there are only a few teachers left. This thesis explores how and when this change came about, and discusses what this meant for the Society. It argues that the exit of the teachers is related to the rising standard of mathematics, but even more to a change in the Society’s printing policy in the 1920s, that turned the Society’s Proceedings into a pure research publication and led to the death of the ‘teacher journal’, the Mathematical Notes. The thesis also argues that this change, drastic as it may seem, does not represent a change in the Society’s nature. For this aim, the role of the teachers within the Society has been studied and compared to that of the academics, from 1883 to 1946. The mathematical contribution of the teachers to the Proceedings is studied in some detail, in particular the papers by John Watt Butters. A paper in the Mathematical Notes by A. C. Aitken on the Bell numbers is considered in connection with a series of letters on the same topic from 1938–39. These letters, written by Aitken, Sir D’Arcy Thompson, another EMS member, and the Cambridge mathematician G. T. Bennett, explores the relation between the three and gives valuable insight into the status of the Notes. Finally, the role of the first women in the Society is studied. The first woman joined without any official university education, but had received the necessary mathematical background from her studies under the Edinburgh Association for the University Education of Women. The final chapter is largely an assessment of this Association’s mathematical classes. 941.1
47	Six weeks of high intensity interval training with hyperoxia or normoxia in trained cyclists : A polarized and periodized training approach / Sex veckors högintensiv intervallträning med hyperoxi eller normoxi för tränade cyklister : En polariserad och periodiserad träningsmodell Manselin, Tom, Södergård, Olof January 2015 (has links) Aim The main aim of this study was to investigate the longitudinal effects on cycling performance using a polarized and periodized scheme that was highly supervised and controlled. The second aim was to investigate the effect of using Hyperoxia. The questions used to address the aim were: (1) How does overall performance change after a six-week training intervention? (2) What is the time-course and pattern of performance changes to the training scheme? (3) How does the performance change within the groups? Method Nineteen male and female cyclists started the study (13 male and 6 female), however only 12 completed it (8 male and 4 female). The characteristics for the 12 subjects were: age (year) 33.6 ± 6.8, height (cm) 177 ± 9.1, body mass (kg) 73.4 ± 8.8. Using a randomized, double blind design, the test subjects were divided in to hyperoxia (HOT) (n = 6) and normoxia (NOT) (n = 6) training groups. Over a six week period the subjects followed a controlled polarized periodization that included 15 high intensity interval training (HIIT) sessions (3 x 8 min, 3 x 8 + 4 min, 4 x 8 min & 4 x 4 min) on maximal sustainable intensity (isoeffort) on a cycle ergometer. The dosage of oxygen was administered intermittently by the oxelerate device. A 20 min all out test was performed as pre- and post test. Results The whole group (n = 12) increased mean power output (W) by 6.4 % (P = 0.002). The relative power output (W/kg) increased significantly 8.2 % (P = 0.0011). The HOT group (n = 6) increased their power output by 8.3 % (P = 0.028) and their relative power output increased by 9.4 % (P=0.011). The whole group (P = 12) significantly increased their VO2mean by 4.1 % (P = 0.03) and in the relative value by 5.4 % (P = 0.01) on the 20 min all out test. The whole group also had a significant increase in VO2peak of 3.7 % (P = 0.04). A very strong correlation could be found between the training data and the performance test. Conclusions The training intervention was favourable for increasing performance and VO2peak in cycling. Usage of hyperoxia during the training intervention increases the performance. / Syfte och frågeställningar Huvudsyftet med denna studie var att undersöka de longitudinella effekter på prestation i cykling med hjälp av ett polariserat och periodiserat träningsupplägg som var väl övervakat och kontrollerat. Det andra syftet var att undersöka effekten av att använda hyperoxi. De frågeställningar som hjälpte att besvara syftet var: (1) Hur förändras prestationen efter en sex veckors träningsintervention? (2) Hur anpassar sig försökspersonerna till träningsschemat över tid? (3) Hur förändras prestationen inom grupperna? Metod 19 manliga och kvinnliga cyklister deltog i studien (13 manliga och 6 kvinnliga), 12 fullföljde hela studien (8 manliga och 4 kvinnliga). Karaktäristiken för de 12 försökspersonerna var: ålder (år) 33.6 ± 6.8, längd (cm) 177 ± 9.1, vikt (kg) 73.4 ± 8.8. Försökspersonerna delades in i hyperoxi (HOT) (n = 6) och normoxi (NOT) (n = 6), studien var dubbelblind. Under sex veckor följde försökspersonerna en kontrollerad polariserad periodisering som inkluderade 15 högintensiva intervallträningspass (HIIT) (3 x 8 min, 3 x 8 + 4 min, 4 x 8 min & 4 x 4 min) på högsta genomförbara intensitet (isoeffort) på cykelergometer. Doseringen av syre administrerades intermittent genom Oxelerate-enheten. Ett 20 min all-out test utfördes som för- och eftertest. Resultat Hela gruppen (n = 12) ökade signifikant på prestationstestet (W) med 6.4 % (P = 0.002). Den relativa effekten (W/kg) ökade signifikant med 8.2% (P = 0.0011). HOT (n = 6) ökade signifikant på prestationstestet med 8.3% (P = 0.028) och den relativa effekten ökade med 9.4% (P = 0.011). Hela gruppen (n = 12) ökade signifikant i VO2medel under prestationstestet med 4.1 % (P = 0.03) och i det relativa värdet med 5.4 % (P = 0.01). Hela gruppen hade också en signifikant ökning av VO2peak med 3.7 % (P = 0.04). En mycket stark korrelation hittades mellan träningspassdata och prestationstestet.

48	Embryo Adoption: Implications of Personhood, Marriage, and Parenthood McMillen, Brooke Marie 14 April 2008 (has links) Indiana University-Purdue University Indianapolis (IUPUI) / One’s personal claims regarding personhood will influence his moral belief regarding embryo adoption. In Chapter One, I consider the personhood of the human embryo. If the human embryo is a person, we are morally obligated to permit the practice of embryo adoption as an ethical means to save human persons. However, for those who do not claim that an embryo is a person at conception, embryo adoption is not a necessary practice because we have no moral obligation to protect them. There are still others who claim that personhood is gained at some point during gestation when certain mental capacities develop. I offer my own claim that consciousness and sentience as well as the potential to be self-conscious mark the beginning of personhood. Embryo adoption raises several questions surrounding the institution of marriage. Due to its untraditional method of procreation, embryo adoption calls into question the role of procreation within marriage. In Chapter Two, I explore the nature of the marriage relationship by offering Lisa Cahill’s definition of marriage which involves both a spiritual and physical dimension, and then I describe the concept of marriage from different perspectives including a social, religious, and a personal perspective. From a personal perspective, I explore the relationship between marriage and friendship. Finally, I describe how the concept of marriage is understood today and explore the advantages to being married as opposed to the advantages of being single. Embryo adoption changes the way we customarily think about procreation within a family because in embryo adoption, couples are seeking an embryo from another union to be implanted into the woman. This prompts some philosophers to argue that embryo adoption violates the marriage relationship. In Chapter Three, I further consider the impact of embryo adoption on the family as an extension of the marital relationship as well as the impact of embryo adoption on the traditional roles of motherhood and fatherhood. I examine motherhood by looking at how some philosophers define motherhood and when these philosophers claim a woman becomes a mother. After considering these issues regarding motherhood, I examine the same issues surrounding fatherhood.
