Full textAbstract:
This thesis measures the muon neutrino oscillation at T2K using the first data of the experiment. It concentrates on developing an original selection at Super-Kamionde, the T2K far detector, that improves the performance of the current standard selection. A new, more precise measurement of the oscillation parameters sin2 2 23 and Δm2 32 is performed using this new selection. T2K is a long-baseline neutrino oscillation experiment located in Japan which began data taking in January 2010. It uses the world’s most powerful accelerator generated beam of muon neutrinos intersected by two detectors. The near detector is located 280 m from the beam source while Super-Kamiokande lies 295 km away. Super-Kamiokande is a 50 kt water Cherenkov detector which measures the neutrino beam after oscillation. The determination of the oscillation parameters comes from looking at the disappearance of muon neutrinos from the beam. For this purpose event selection at Super-Kamiokande is optimised for neutrino flavour identification and energy reconstruction, specifically, selecting muon neutrino charged-current quasi-elastic events, primarily with single muon-like Cherenkov rings produced by the outgoing muon. This thesis evaluates two new methods of enhancing the selection to obtain a higher sensitivity from the data, firstly by exploring a multi-variate analysis approach to charged-current quasi-elastic selection, and secondly through the exploration of an additional charged-current single charged pion channel. Out of these only the multivariate based selection produced an improvement in the sensitivity to oscillation with respect to the standard selection. A first analysis of the data collected until March 11th 2011 using the above described improvement is presented in this thesis. A value of 2:68+0:12 −0:18 × 10−3 eV2 was recorded for Δm2 32 and 0:999+0:001 −0:009 for sin2 2 23. 2

Full textAbstract:
Supernova (SN) iPTF13bvn in NGC 5806 was the first Type Ib SN to have been tentatively associated with a progenitor in pre-explosion images. We performed deep ultraviolet (UV) and optical Hubble Space Telescope observations of the SN site similar to 740 days after explosion. We detect an object in the optical bands that is fainter than the pre-explosion object. This dimming is likely not produced by dust absorption in the ejecta; thus, our finding confirms the connection of the progenitor candidate with the SN. The object in our data is likely dominated by the fading SN, implying that the pre-SN flux is mostly due to the progenitor. We compare our revised pre-SN photometry with previously proposed models. Although binary progenitors are favored, models need to be refined. In particular, to comply with our deep UV detection limit, any companion star must be less luminous than a late-O star or substantially obscured by newly formed dust. A definitive progenitor characterization will require further observations to disentangle the contribution of a much fainter SN and its environment.

Full textAbstract:
Thesis (M.A.)--Boston UniversityVitamin D has proven to be an important factor in health through a plethora of studies. Tachysterol is a photoproduct of previtamin D with sun or ultraviolet radiation exposure. While vitamin D is well known for its importance in bone health, the biologic function of tachysterol is unknown. Many vertebrates and fungi can produce vitamin D from a precursor after UV irradiation or sun exposure, including white button mushrooms. This project aims to determine if tachysterol might have a biologic function in white button mushrooms by determining if the disappearance of tachysterol2 was due to some active process in live mushrooms. To provide evidence that tachysterol serves a function, tachysterol2 disappearance in white button mushrooms was monitored after 24 hours. The aim was to create conditions in a white button mushroom, including freezing and microwaving them to determine their effects on tachysterol2 disappearance at 24 hours. The idea was that freezing or microwaving the mushroom would disrupt any metabolic process in the mushroom, providing a clue as to the mechanism of tachysterol2 disappearance. The hypothesis was that freezing and microwaving the white button mushroom would cause a reduction in tachysterol2 disappearance. To evaluate this, 1) white button mushrooms were irradiated with ultraviolet radiation (UVB, 290nm-320nm), 2) an irradiated white button mushroom was frozen, and 3) an irradiated white button mushroom was microwaved. These white button mushrooms were biopsied in triplicate, extracted, and run on high-performance liquid chromatography in order to determine the concentrations of tachysterol2 in the mushrooms. A white button mushroom without UVB irradiation was biopsied in triplicate and extracted to confirm that the store-bought mushrooms did not contain tachysterol2. A tachysterol2 standard was incubated in organic solvent to determine if tachysterol2 was stable. The results showed statistically significant decrease in tachysterol2 for the irradiated mushroom, the frozen irradiated mushroom, the microwaved mushroom 24 hours after irradiation, compared to the standard tachysterol2 in organic solvent. The decrease in tachysterol2 in the microwaved mushroom was 65% in 24 hours, which was not significantly less than in the irradiated mushroom and the frozen irradiated mushroom (p= 0.10 and 0.22, respectively). The decrease in tachysterol2 for the frozen mushroom was 93%, which was not significantly less than the irradiated mushroom (p = 0.21). These findings suggest that microwaving a mushroom at 5mW and 60 seconds and freezing a mushroom does not significantly interfere with metabolic processes that may involve tachysterol2, although microwaving a mushroom trended towards less of a decrease in the tachysterol concentration.

Full textAbstract:
Melting into the Margins intervenes in the academic and media debate about normality: the white nuclear family and white middle class men. This thesis traces the emergence of the contemporary discourse which suggests that the normal is being displaced into the margins, away from the centre, 'disproved' as a lived condition and shown to be ‘untrue’ as an ideological concept and examines the implications and effects of this discourse. A new discourse of the normal is deemed necessary by the academic disciplines of masculinity and family studies because they argue that we live in a new age of tolerance, equality, meritocracy and plurality. The disciplines of masculinity and family studies that this thesis critiques argue that in this new age and new society the ‘old’ idea of a white, middle class, gendered, heterosexual normality is becoming unworkable and obsolete. This thesis examines the new discourse itself and its archive (Foucault, 1972), in the form of contemporary representations of white men and the white, middle class, heterosexual nuclear family. Beginning with the idea that white men were traditionally and historically invisible this thesis argues that this was never so and that the centre of our society has always been visible. This thesis offers a critique of the current project from the academy and from the media that proposes to ‘make-the-centre-visible’ in order to 'prove' that normality does not exist. I argue that this project, which exposes failure, doubt and abnormality beneath the surface appearance of the normal is a project set up by white middle class people for white middle class people. The new project, its discourse and archive attempt to demonstrate that no-one has any extra-ordinary power in our society because of race, gender or class. This thesis argues that this demonstration evidenced in the academy and the media takes an extreme anti-essentialist view point that eventually denies that there are any limits to choice or opportunity. The denial of an excluding and exclusionary normal predicated on concepts of difference suggests a pure meritocracy, which helps to justify the continuing domination of white men. The aim of Melting into the Margins is to offer a critique of the current discourse of normality and an examination of its archive and to offer ways forward that can truly fulfil the stated objectives of masculinity and family studies: the deconstruction of the exclusive, excluding white, middle class centre of British society - the normal.

Full textAbstract:
The first part states the reasons for the disappearance of the body: the influence of modern technology, effects on self-perception and on the perception of reality. It questions how to deal with the shift from physical reality as reference of existence toward an infinite spectrum of virtual realities. The second part concerns a way of thinking - a fiction to explain the phenomena of disappearance - in drawing a parallel to recent thinking models in physics formulating the disappearance of matter. This shift of thinking is so fundamental that it literally reverses our notion of body and materiality. The thesis tries to imagine and to explain a reappearance of the body, the birth of the concrete out of the immaterial. The last part images and models necessary, ambiguous spaces in a world where inside and outside, weight and lightness, solid and immaterial are no longer clearly defined positions but zones, uncertainties, overlays.Department of Architecture

Full textAbstract:
The NOvA experiment consists of two functionally identical tracking calorimeter detectors which measure the neutrino energy and flavour composition of the NuMI beam at baselines of 1 km and 810 km. Measurements of neutrino oscillation parameters are extracted by comparing the neutrino energy spectrum in the far detector with predictions of the oscillated neutrino energy spectra that are made using information extracted from the near detector.

Full textAbstract:
MINOS is a long-baseline neutrino oscillation experiment. It consists of two large steel-scintillator tracking calorimeters. The near detector is situated at Fermilab, close to the production point of the NuMI muon-neutrino beam. The far detector is 735 km away, 716 m underground in the Soudan mine, Northern Minnesota. The primary purpose of the MINOS experiment is to make precise measurements of the "atmospheric" neutrino oscillation parameters (Δm2atm and sin22θatm). The oscillation signal consists of an energy-dependent deficit of vμ interactions in the far detector. The near detector is used to characterize the properties of the beam before oscillations develop. The two-detector design allows many potential sources of systematic error in the far detector to be mitigated by the near detector observations. This thesis describes the details of the vμ-disappearance analysis, and presents a new technique to estimate the hadronic energy of neutrino interactions. This estimator achieves a significant improvement in the energy resolution of the neutrino spectrum, and in the sensitivity of the neutrino oscillation fit. The systematic uncertainty on the hadronic energy scale was re-evaluated and found to be comparable to that of the energy estimator previously in use. The best-fit oscillation parameters of the vμ-disappearance analysis, incorporating this new estimator were: Δm2 = 2.32+0.12-0.08 x 10-3eV2 sin22θ > 0.90 (90% C.L.). A similar analysis, using data from a period of running where the NuMI beam was operated in a configuration producing a predominantly V‾μ beam, yielded somewhat different best-fit parameters Δ‾m2 = (3.36+0.46-0.40 (stat.}) ± 0.06(syst.)) x 10-3eV2, sin22‾θ =0.86+0.11-0.12(stat.) ± 0.01(syst.). The tension between these results is intriguing, and additional antineutrino data is currently being taken in order to further investigate this apparent discrepancy.

Full textAbstract:
Deforestation of flooded (várzea) and non-flooded (terra firme) forests caused by firewood consumption at tile factories (olaria) was investigated in Abaetetuba Island at the Amazon estuary. Várzea is spatially limited, the area is only 3% of the whole Amazon, however, it is heavily influenced by human activities, especially by the cultivation of acaí palm (Euterpe oleracea Mart.). The trees are cut down for the olarias. The number of tree species are small, and they have less wood density than terra firme tree species because the várzea is flooded twice a day throughout the year. Terra firme forests, which are also secondary forests, receive less human impact, and have more tree species and more individual trees with a growth extension that exceeds the species in the várzea forests. The deforestation was examined by comparing forest biomass in a unit area to firewood consumption at olarias. The annual area of deforestation was estimated by using the combination of tree species in the firewood and human impact in the várzea forests. Then the estimation was extended to the whole island, assuming that the forests were rotatively cleared every 25 to 30 years. The results indicated that the area of deforestation was 6,870ha/25 years to 8,337ha/30 years, and that it was smaller than the island. However, logging is not only for fuel at olarias. If Belém's economic influence becomes stronger, and electric energy is not diffused throughout the island, the lumber consumption will accelerate and the increase might make the forest disappear faster than estimated.

A Vμ disappearance analysis performed on the dataset collected during the first physics run of the T2K experiment is presented. This dataset represents an accumulated exposure of 3.23 x10¹⁹ protons on target (POT). A total of eight events passed all the selection criteria at the far detector, Super-Kamiokande, with an expectation of 22.8 ± 4.8(stat)+3.7-3.7(syst). A two flavor neutrino oscillation fit was performed with systematic uncertainties using a Markov Chain Monte Carlo method and a Bayesian approach. The sin² 2θ23 oscillation parameter was constrained to the physical region. Under these conditions, we found best fit values for the oscillation parameters of sin² 2θ23 = 0.83+016-0.18 and Δm²32 = 2.9+0.8-1.0 x 10⁻³ eV²/c⁴.

Full textAbstract:
The resettlement of Baltic Germans from Estonia and Latvia to the Polish territories initiated the dissolution of the Baltic German community and its unique identity, largely causing hardship and suffering throughout the occupation in Poland. The subsequent escape from the Red Army and deportations by the Poles at the end of World War II completed the disbanding. It brought innocent families, as well as Baltic German soldiers, to and beyond the limits of their ability to endure pain and suffering. Yet, throughout the process, Baltic Germans’ reaction to the opportunities and crisis varied greatly. The following study will uncover the diverse fates Baltic Germans endured and reveal the range of Baltic German’s culpability and victimhood throughout the resettlement process and the subsequent migration west.

Lent, Michael. "Seducing disappearance : adumbrational space and sacrifice from site to image." Thesis, University of Lincoln, 2014. http://eprints.lincoln.ac.uk/14696/.
Full textAbstract:
There is a crisis of alterity in which otherness is threatened by its opposition to a system of exchange. According to Jean Baudrillard: “Alterity is in danger. It is a masterpiece in peril, an object lost or missing from our system…”1 This research focuses on the otherness of space in order to prevent its ultimate dissolution, promoting a spatial practice of radical alterity. The project takes as its impetus the ideas of disappearance put forth by Baudrillard and Paul Virilio. However, it shifts their ideas, which were originally ascribed to objects into a new emphasis, instead applying them on to space. It takes similar stances based on the anti-productivist perspectives of Baudrillard and Georges Bataille with the view that the visual arts have remained by the wayside as the entire culture is now being threatened by the extermination of space…”2 This research takes a renewed action in this regard by developing theory and works that are informed by the fatal strategies and ‘raw’ phenomenology of Baudrillard. This research employs an artistic effort towards radical alterity as a practical one. It combines a phenomenology of the experience of space with strategies of asyndetic 1 Baudrillard, J. & Guillaume, M., 2008, Radical Alterity, Semiotext(e), Los Angeles. P. 113. 2 Virilio, P. & Lotringer, S., 2005, The Accident of Art, Semiotext(e), Los Angeles. P. 29. ii fragmentation and mobility as a production of perception of the world as Other in order to challenge a system of disappearance. This strategy advances discovery of the adumbrational potentialities of site rooted in Husserlian phenomenology and artistic practice, ultimately attempting to break a cyclical system of exchange that causes everything to disappear. This thesis proposes that the dissolution of space is more precisely a transfiguration of site into a known and utilised place. It represents a movement into realised place, and a disappearance of the original space that once was. In this way, it has been consumed as a product into the system of difference and absorbed into homogeneity and entropy. Rather than a mediated practice responding to space as commodification, this research instead proposes a different practice; a rethinking of the way we utilise space. Through this it seeks to offer a radical practice, one that preserves the alterity of unnamed space as an act towards singularity—a singular space that resists the urge towards homogeneity. Summarising this method, Lewis Keir Johnson described portions of this thesis in the introduction to Mobility and Fantasy in Visual Culture with: Michael Lent ... outline(s) projects involving moving images of space and place. Lent’s work reengages with Baudrillard’s account of an accelerating dystopia of space and place by reminding us of Husserl’s phenomenology of objects and their penumbral “adumbrations.” Not where such objects are lost but found, this obscurity that enables only partially able perception also iii provokes practices of space, as he argues, following the work of Michel de Certeau, revisionist theorist of flaneurism. Lent takes this back to the problem of belief in certain knowledge of places, their limits and perdurance, drawing us closer to an experience of multi-projection video that invites imaginaries of phasal histories of place and pleasure in space.3 An aim of this thesis is to further develop an existing discourse and a movement towards finding possible resolutions, particularly within a studio practice framework. An examination of how one might approach these tendencies and better understand this disappearance into what is represented is crucial to the practice-based methodology. The fugacious terrain of this investigation (both of its subject matter and its theoretical provision) requires this research to focus and espouse on that which is experimental, intentional, and sometimes impenetrable— what is lost in representing experience. This thesis is arranged in several parts. Firstly, there is a progressional narrative that sites the theoretical, literary, and artistic contexts that situate this research. Then there is a discussion of the relationship between writing and practice. This is followed by an examination of the relationship between sacrifice and the image. This serves to set the context and methodology for this investigation. Next, there is 3 Johnson, L., 2013, Mobility and Fantasy in Visual Culture, Routledge Advances in Art and Visual Studies. Routledge: Taylor & Francis, London. P. 90. iv a discussion of the adumbrational potentiality of site, based on a phenomenological concept set forth by Husserl. An examination of the work of Robert Smithson in relation to the research project follows, which highlights the artist’s intent to examine site but also what is ultimately destroyed through the utility of making art. This is followed by a discussion of what a spatial practice might be, and how one might go about this practice in a more experiential but less deterministic and detrimental way. Lastly, there is a series of phenomenologically driven investigations into the studio component of this thesis and a conclusion of future directions this research might take.

Full textAbstract:
T2K is a long-baseline accelerator neutrino oscillation experiment using the high-intensity ν_μ beam produced at J-PARC. Sitting 295 km away, the giant Super-Kamiokande detector, a 50 kt water tank instrumented with 11,129 photosensitive detectors, sees a narrow band beam peaked at 600 MeV. The baseline to energy ratio is finely tuned for studying neutrino oscillations at the atmospheric neutrino squared-mass splitting. The beam is also sampled 280m downstream of the neutrino production target by a series of finely segmented solid scintillator and time projection chamber detectors. Observing changes in the neutrino beam between the two detectors allows oscillation parameters to be accurately extracted. A ν_μ-disappearance analysis was performed on the combined T2K Run 1+2+3+4 dataset, corresponding to integrated J-PARC neutrino beam exposure of 6.57x1020 POT, in a framework of three active neutrino flavour oscillations including matter effects in constant-density matter. The observed reconstructed energy spectrum of 1 μ-like ring events was fitted, and separate fits were made for the normal and the inverted mass hierarchies.

Full textAbstract:
MINOS is a long baseline neutrino oscillation experiment. It measures the flux from the predominately muon neutrino NuMI beam first 1 km from beam start and then again 735 km later using a pair of steel scintillator tracking calorimeters. The comparison of measured neutrino energy spectra at our Far Detector with the prediction based on our Near Detector measurement allows for a measurement of the parameters which define neutrino oscillations. This thesis will describe the most recent measurement of muon neutrino disappearance in the NuMI muon neutrino beam using the MINOS experiment. The general method of a disappearance analysis at the MINOS experiment will be outlined, the selection of events, extrapolation between detectors, and fitting the data to the atmospheric mixing parameters. An analysis of the full MINOS Forward Horn Current charged current muon neutrino interactions sample is detailed, with a best fit to the atmospheric mixing parameters in a two flavour approximation of $\Delta |m^2_{atm}| = 2.42\times10^{-3}~\mathrm{eV}^2$ and $\sin^2(2\theta_{23}) = 0.936$. The change to a three flavor analysis with matter effects from a simple two flavour approximation is described, with a very slight preference of $-2\Delta \log(L)=0.01$ for the inverted hiearchy found. A study of the NuMI beam is also shown, with potential locations for new oscillation experiments in the NuMI beam discussed.

Full textAbstract:
Thesis (Ph.D.)--Boston UniversityThis dissertation probes critical questions about the relationship between the production of cultural meanings, social power, and material objects. By using the public discourse on traffic accidents in the United States as a historical case study, this study investigates in particular the various ways by which social groups respond to unintended technological consequences and dangers within definitional processes of collectively constructing a social problem. The textual-thematic analysis draws largely upon theories from social problems literature and science & technology studies, as it looks at a number of salient historical claimsmakers, sites of discourse production, and cultural vehicles of meaning making. Specifically, the contributions of the private insurance industry, safety establishment, consumer market, automobile clubs, and printed media are closely dissected to flesh out the contours and content of the accident problem's construction and development through time. In line with a contextual constructivist approach to social problems analysis, the research has observed the emergence, evolution, and eventual waning of the accident issue along several structural anchors that provide possible explanations for some of these dynamics. To a great extent, the traffic accident problem has gradually 'disappeared' in America throughout the twentieth century - a disappearance that is not physical but conceptual. Specifically, it means that the troubling social condition is defined as something to live with, a necessary evil of which there seems to be limited ability or desire to substantially affect or eradicate. The sociological concept I employ to name this particular trajectory towards problem attenuation is normalization. Applied to the case analyzed here, the findings offer a way to understand the processes by which traffic accidents become nom1alized in America as an acquiescent price to pay for the benefits of the automobile. Theoretically, these conclusions have laid the groundwork for producing a hypothetical model of social problems normalization. The model highlights the role played by several cultural devices of claimsmaking in affecting issue attenuation or 'disappearance.' When the problem is constructed through highly technicizing, commensurating, commodifying, and socially controlling modalities of sense making, the likelihood of its normalization and eventual floundering increases.

The Mascouche site (located near Montreal, Quebec) served as a petroleum waste dump ground during the 1950's and 1960's. It then housed a petroleum waste incinerator from 1969 to 1974.Laboratory forced air biostimulation studies were performed on a soil sample from this site for two reasons: (a) high permeability sand presented optimal conditions for the application of biostimulation and (b) the wish to test the effectiveness of the method in site reclamation.
The concentrations of various pollutants, such as PAHs, PCBs and heavy metals, were first determined in the soil samples. Biological degradation using forced aeration was responsible for at least 20% of PAH disappearance over 20 days. Various soil microorganisms were isolated, in soil extract media, in order to identify biodegrading activity.
The results obtained suggested that bioremediation as the sole decontamination method may not be as effective as anticipated. The results also show that chemical/physical mechanisms are also of importance. Procedures for forced aeration bioremediation should include monitoring of soil atmospheric parameters to account for possible volatilization effects.

Dennis, Stephen. "Muon antineutrino disappearance and non-standard interactions at the T2K experiment." Thesis, University of Warwick, 2015. http://wrap.warwick.ac.uk/77362/.
Full textAbstract:
T2K is a long-baseline neutrino oscillation experiment, which studies the changing avour composition of a beam over a 295 km baseline from an accelerator at J-PARC to Super-Kamiokande, a 50 kt water Cerenkov detector. The T2K neutrino beam has an energy peak at 0.6 GeV which gives strong sensitivity to oscillations at the atmospheric mass squared splitting. The beam can be run in two modes, producing a beam either dominated by neutrinos or by antineutrinos. Collecting data in antineutrino-mode allows the measurement of the neutrino mixing parameters on antineutrinos only. In the first analysis of T2K antineutrino-mode data, we use beam data collected up to June 2015 to measure sin2⊖23 and j m2 32j. The 90% CL allowed values for mixing angle are 0.327 < sin2⊖23 < 0.692 (normal hierarchy) and 0.332 < sin2⊖23 < 0.697 (inverted hierarchy). The 90% CL allowed values for mass splitting are 2.03x10-3 eV2 < j m2 32j < 2.92x10-3 eV2 (normal hierarchy) and 2.03x10-3 eV2 < j m2 31j < 2.92x10-3 eV2(inverted hierarchy). This is the world's best measurement in sin2⊖23. A difference between neutrino and antineutrino survival probabilities could result from physics beyond the Standard Model, known as non-standard interactions. A simultaneous fit to the T2K neutrino-mode and antineutrino-mode datasets allows for a direct search for such interactions. We see no evidence for this hypothesis.

Raguz, Christopher. "Paranoid Epistemologies: Essays on Thomas Pynchon and the Scene of Disappearance." Scholarship @ Claremont, 2019. https://scholarship.claremont.edu/cmc_theses/2118.
Full textAbstract:
The following five essays are connected by their reference to a scene – imagined by the author Thomas Pynchon. The disappearance of historical cause, the subject, and the human constitute this epistemological scene. Each essay can be read without logically building off of any other – yet they form a wider assemblage of interpretative theory. These are fragments capable of recombination in any order. They shun systematization but welcome kinship. Pynchon's fiction is the substrate underlying each. Abstract machines of theorists thinking on similar wavelengths are used as catalysts in an effort to force a reaction – an attempt to transmute the stories of paranoid schlemihls into yet more paranoid epistemologies.
How do we understand the degree to which we are organized by whatever systematizes? How do we relate to whatever organizes our knowledge, our identities? What, exactly, is playing us? These are the anxieties these essays share with Pynchon's characters and formulate the questions driving their theory. Call it the Post-Modern, the Post-Human, or any other Post, Pynchon anticipated its event horizon half a century before its more obvious implications made themselves clear. If we have passed fully over this horizon, figuring out where we are and what's going on has become a question of survival, and Pynchon's anticipation of our contemporary scene have become increasingly salient. These essays offer paranoid epistemologies for the age of disappearance.

Full textAbstract:
Ma pratique de plasticienne a été bouleversée il y a une douzaine d'années. Ce qui fit évènement : un sachet de thé accroché à une fenêtre. J'ai commencé alors mes recherches autour du thé. Ce travail est le fruit d'expériences qui engagent une sorte de périple intérieur nouveau.Dans ce champ d'expériences, comment ne pas s'égarer, quelles procédures convoquer afin de ne pas sombrer dans l'errance absolue? L'avancée se fait dans un entre-deux, entre errance et ritualisation. Le premier concept ouvre le champ des possibles, le second structure, jalonne afin d'éviter de sombrer dans le non·sens. Les deux questionnent l'espace, le temps, ils se renvoient l'un à l'autre: ainsi le rituel par son caractère répétitif peut s'assimiler à l'errance dans un espace temporel commun.Le travail de mémoire s'articule à partir du "Joumal d'errances et d'autres lieux" (en se référant au journal d'Aran et d'autre lieux de Nicolas Bouvier). Afin de répondre au sujet qui nous préoccupe, ce journal s'élabore dans une sorte de vagabondage intellectuel, sans contrainte temporelle. Le rituel de la "proella", rituel funéraire spécifique à l'île d'Ouessant a un retentissement fondamental dans mes recherches et renvoient aux deux notions fondamentales: l'errance à travers le corps du défunt mort en mer et le rituel qui met fin à cette errance. li interroge également sur la disparition, la matière à l'oeuvre, la demeure {antinomique à l'errance). Le champ qui nous intéresse est le champ poiétique tel qu'il se crée au travers de cette pratique. Il s'articule comme un va-et-vient entre l'engagement artistique et la volonté de s'interroger sur ce qui fait oeuvre en l'englobant dans une problématique plus générale dans le champ de l'art contemporain.Si l'art c'est la vie, la seule limite serait-elle la disparition de l'art? On peut se demander alors : où en sommes-nous?Comment donner plus de vie à la vie de l'art ? En tentant d'aller plus loin que la vie, cheminons nous vers une mort annoncée? Ne serait-ce pas clans ces deux extrêmes que se situerait le champ de l'art? Une telle distension peut-elle amener à ce que nous nous perdions définitivement?My practical experience as a visual artist was completely changed twelve years ago. The event consisted in a tea bag hanging out of a window. l then started a research around Tea. This work is the fruit of several experiences leading to a kind of new inner Quest.In this field of experiences, how not to go astray? What method to apply, so that we do not end up drifting? I move on intoan intervening sphere between Drifting and Ritualizing. The first notion enlarges the scope of possibilities, the secondstructures and prepares the ground for my study, so that we avoid none-sense. Both call space and time into question, both refer us to one another - Due to their repetitive nature, Rituals can appear similar to Drifting through sorne commontemporal Space.The Gesture of Remembrance will be performed from the "journal d'errance et d'autres lieux" (with reference to Nicolas Bouvier's "Joumal d'Aran d d'autres lieux"). To tackle the subject under study, this journal hinges upon some sort intellectuall drifting without temporal constraint. The Ritual of "proella", which is a funeral Ritual specifie to the Isle of Ouessant, impacts on our rescarch fundamentally,and points to two essential notions . drifting along through the Corpse of the deceased Person who died at sea, and the Ritual which puts an end to this Drifting. It also makes think about Disappearance, Matter and Resting Place (the reverse of Drifting'). The field that interests us is the poietical field as created by this usage. It is developed as a to and fro movement between the Artist's Engagement and the Will to Wonder what the work of Art is, including it within a more general problematics in the field of contemporary Art. If Art is Life, would the only limit be the Disappearance of Art? One may then wonder. Where do we stand? How to render Art's Life more animated? \Vhile we strive to go beyond Life, arc we progressing towards an announced Death? Isn't it between the two extremes that the field of Art is to be found ? Can such a Distension make us get lost without remedy ?

Full textAbstract:
In experiment I), dry matter disappearance (DMD) and nitrogen disappearance (ND) of raw soybeans (RAW), solvent extracted soybean meal (SBM), heat treated whole soybeans (HT), mechanically extracted soybean meal (MEX), dry extruded soybeans (DEX), and wet extruded soybeans (TEX), were studied in situ for times of 3, 6, 12 and 24 h of rumen exposure. Five gram, air dry, samples were suspended in the rumen of a lactating Holstein cow fed a total mixed ration twice daily. The percent DMD for 24 h was as follows: RAW-85.9; SBM-56.6; HT-39.0; MEX-40.2; DEX-28.0; TEX-43.3. The greatest DMD was observed with RAW and was greater than all others (P<.01), followed by SBM which was significantly greater than all but Raw (P<.01). DEX presented the lowest DMD when compared to all other (P<.01). Percent ND values for 24 h for the soy products were: RAW-90.8; SBM-47.0; HT-32.7; MEX-23.7; DEX-16.5; TEX-23.0. The ND for RAW was significantly greater (P<.01) than all others, while the ND for SBM was similar P>.01) to HT but greater (P<.01) than MEX, DEX and TEX. ND for HT, MEX, DEX and TEX were similar (P>.01). Significant differences were observed in DMD and ND of various soybean products. As expected a high degree of degradation and ND was observed with raw soybeans. The application of heat decreased DMD and ND in SBM and application of greater heat (HT, MEX and DEX) and application of heat with moisture (TEX) resulted in products with lower DMD and lower ND.
In experiment II) wheat straw acid detergent fiber (ADF) was subjected to in situ DMD and ND studies. Effects of time (612-24 h) and sample weight (1-2-3 grams) were evaluated. A lactating Holstein cow being fed a mixed ration was used. ADF dry matter (DM) weights (after incubation) expressed as a % of the original sample, were as follows: one gram: 101, 110 and 136; two grams: 99, 106 and 110; and three grams: 97, 110 and 114 for 6, 12 and 24 h respectively. The ADF DM weights of the one and two gram samples were significantly higher (P<.05) for 12 and 24 h than 6 h. When sample sizes were combined for each time, comparisons found 24 h to be significantly higher (P<.01) than 6 h. The DM changes were also reflected and magnified in the % N changes in the ADF residues. The amount of N of the one gram ADF samples increased 32% after 6 h, 122% after 12 h and 287% after 24 h (24>12>6-P<.01), and for two grams 29%-6 h, 97%-12 h and 117%-24 h (24>12>6-P<.05), and for three grams 34%-6 h, 140%-12 h and 142%-24 h (24 and 12>6-P<.01). Potential problems with DM and N contamination of ADF residue with in situ studies were demonstrated with small increases in DM weights and larger increases in N content.

"EFFECT OF DIETARY CONCENTRATE LEVELS ON IN SITU DRY MATTER DISAPPEARANCE, NEUTRAL DETERGENT FIBER DISAPPEARANCE AND DIGESTION KINETICS OF ALFALFA HAY, WHEAT STRAW AND STEAM PROCESSED AND FLAKED MILO GRAIN." Diss., The University of Arizona, 1986. http://hdl.handle.net/10150/183830.
Full textAbstract:
A replicated 3 x 3 latin square design (3 periods and 6 rumen fistulated steers) was utilized to investigate the effect of dietary concentrate levels (30, 60 and 90%) on the in situ disappearance of dry matter (ISDMD) and neutral detergent fiber (NDF) and kinetics of fiber digestion of alfalfa hay, wheat straw and steam processed and flaked milo (SPFM). Concentrate levels of 30 and 60% did not affect (P > .05) ISDMD or NDF disappearance from any of the substrates. However, ISDMD and NDF disappearance of all substrates were depressed (P < .05) by the 90% concentrate diet. The degradation of the potentially digestible fiber in these substrates followed first order kinetics at all concentrate levels. Fiber digestion kinetics were not affected (P > .05) by dietary concentrate levels of 30 or 60%. Incubation of substrates in animals receiving the 90% concentrate diet resulted in lower potential extent of digestion (P > .05) and decreased rate of degradation (P > .05) for all substrates. However, digestion was not complete even after incubations of 168-h, and thus, it is possible that the potential extent of digestion was underestimated. For all substrates lag time of digestion appeared to increase in the 90% concentrate diet. However, influx of NDF-like material into the bag during incubation makes the validity of the lag times obtained in situ questionable. Ruminal pH was depressed in animals consuming the 90% concentrate diet and could be at least one of the factors responsible for the decreased (P > .05) fiber digestibility in this diet. Mean ruminal pH of 6.5 (30 and 60% concentrate diets) did not depress (P > .05) fiber digestibility while a mean pH of 6.2 resulted in a lower (P > .05) fiber digestibility in the rumen.

Full textAbstract:
This study began with a personal recognition of the importance of space in my creative process. As a theatre director, I need to see and feel the space for a work before I know how to direct or create the performance. Once I know what the space is everything falls into place. This fascination with space in my creative process has triggered a larger investigation into the operations of place in the making of contemporary performance.
The first part of the thesis embarks on a series of theoretical and creative journeys to learn more about place and how it is positioned within contemporary performance. It journeys
through contemporary theory on place in the work of Gaston Bachelard, Edward S. Casey, Henri Lefebvre, Michel de Certeau and Marc Auge. These theorists think about place as a product of human dwelling and social production, and its conceived dimensions as psychic structures for a culture that embodies the fantasies, desires and visions of our places.
The thesis traces my physical journey from Australia to the Wooster Group in New York City and Forced Entertainment in Sheffield where I observed and worked with two significant contemporary performance companies, each in their own place. The Wooster Group has maintained an ongoing osmotic relationship with SoHo, absorbing the underground experimentations of performance makers in the 1960s, to the retail experimentations of Prada today in the now gentrified district. Similarly, Forced Entertainment has lived through a rejuvenation of Sheffield, which is examined in relation to a shift in the companys aesthetic and style. I also encountered these
companies and another, Societas Raffaello Sanzio, at festivals in Australia. Societas Raffaello Sanzio avoid endless repetition on tour with Tragedia Endogonidia a project that creates a new work for each place it performs in balancing the desires of the international performing arts market with a portable strategy towards place.
The second part of the thesis returns to examine the imaginaries of Australia and Adelaide, the nation and city in which I work. It considers the impact of these imaginaries in a performance laboratory called The Rope Project, which explores Adelaides myth of The Family and Alfred Hitchcocks Rope. Lacans notion of the imaginary is used to examine the national imaginary of Australia as place where people disappear, an imaginary maintained by representations that imbue the Australian landscape with a hostile agency. The thesis argues that the erasure implicit in the colonial concept of terra nullius has informed a national imaginary obsessed with disappearance. A dossier of The Rope Project reveals the myth of The Family explored as a representation in the performance laboratory. The Family is the result of two competing imaginaries connected to the city of Adelaide: its founding utopian imaginary, the Athens of the South, and its horror-inverse, The Worlds Murder Capital. This mythology was generated as a conservative backlash to the social reforms of Premier Don Dunstan and maintains a perceived connection between homosexuality and deviance. The thesis offers in conclusion fresh insights into the use of the imaginary and lived aspects of place in the creation of new performance works.

Elle comprend à la fois l'étalonnage relatif au moyen de muons cosmiques horizontaux et l'exploration de plusieurs options pour la détermination de l'échelle d'énergie absolue. Enfin, la thèse présente une nouvelle méthode de sélection des candidats antineutrinos basée sur l'analyse de la partie électromagnétique du signal de désintégration bêta inverse et leur classement en fonction de la géométrie des événements dans le détecteur (topologies).

Three main contributions to this search are reported. The first one describes the new reconstruction method based on the ML-EM algorithm. It is aimed at transformation of the raw detector response to the list of positions (with dedicated energies) where actual physics interaction in the detector took place. The second one describes the energy calibration of the detector. It includes both relative calibration with the cosmic horizontal muons and exploration of several options for the absolute energy scale derivation. Finally, the thesis presents a novel method for selecting antineutrino candidates based on the analysis of the electromagnetic part of the inverse beta decay signal and categorising them according to the geometry of the events in the detector (topologies). The analysis was developed blindly and the method was validated with a small fraction of the data sample

Full textAbstract:
Recent scholarship on the impact of neoliberalism in education centers on the creation of policies, curricula, and programming, positioning education as a system that produces marketable, entrepreneurially-minded, global workers (DeLissovoy, 2015; Peters, 2017). What is less known are the ways in which economic principles and mechanisms work in school systems, and how these changes affect teachers and social studies disciplines. Through a critical discourse analysis of policy and other official education documents, interviews, and focus groups with experienced administrators and social studies teachers in the province of Nova Scotia, Canada, I argue that changes in education policy between 1994-2016 have altered the purpose of public education, entangling schooling with economic and accountability goals of the province. The purpose of this qualitative study is threefold: first, using Foucault’s (2008), and later Stephen Ball’s (2013a) theorization, I investigate the extent to which neoliberal governmentality shaped education policy changes in Nova Scotia between 1994-2016. Second, I examine how these changes implicate educators in practice, including the ways teachers perceive changes to their jobs over the last decade. Lastly, I explore the state of high school social studies in Nova Scotia as a site to test the micro-effects of neoliberalism and governmentality in changing policies and practices in education. I conclude that neoliberal governmentality has emerged in distinct patterns in Nova Scotia, which articulate with specific policy technologies and practices in education. Such patterns include the strategic use of economic and educational crises to forward neoliberal policy reform, the expansion of governmental mechanisms to track student and teacher performance, and the dis-articulation of social studies disciplines from the education system.

Halden, Grace. "'If this is a man' : technological development and human disappearance in US Sf since 1945." Thesis, Birkbeck (University of London), 2014. http://bbktheses.da.ulcc.ac.uk/93/.
Full textAbstract:
This thesis examines how literal and figurative disappearance can be said to have occurred through certain technological developments after World War II. This study investigates key concepts of the human condition alongside notions of disappearance, underpinned by the contextual framework of Primo Levi’s pivotal question and statement: ‘if this is a Man’. As a survivor of Auschwitz, Levi reflected on threats to the human through Holocaust testimony in If This is a Man (1947) and through his science fiction (sf) which explored technological perils after 1945. Like Levi, my work focuses on the ways in which ‘Man’ can be challenged and undermined. While my work uses a similar approach, it goes further by applying ideas of disappearance and by exploring technologies outside Levi’s remit and within US sf. To look at the concept of human replacement and destruction, I build on the philosophy of Jean Baudrillard who argued that humanity is at risk of figuratively ‘disappearing’ through a blurring of boundaries between the real and the artificial. Baudrillard speaks of losing traditional concepts of the human condition through simulacra and technological dominance. I combine Baudrillard’s idea of disappearance with Levi’s concerns over technological threats to the human. In this thesis, I speak of literal disappearance as involving death (especially to the collective through genocide or extinction) and figurative disappearance through an alteration of the traditional concept of what it means to be human. Through representative sf texts, I explore how many writers have portrayed the human as under pressure through certain technological advancements especially after World War II. My thesis is arranged thematically, tracing three key technological epochs within a chronological structure. The themes for the three parts are intended to highlight some key concerns emerging from sf which relate to the human condition and disappearance, such as the threat of the nuclear, the emergence of cybernetics, and the development of artificial intelligence. I use these historic events to reflect on how US sf explores technological apocalyptic themes.

Full textAbstract:
A study of monomethylmercury (MMHg) concentrations in the water and sediment of
the hypoxic zone in the northeastern Gulf of Mexico was conducted on several cruises
between April 2004 and May 2005. Surface water MMHg concentrations were low and
constant throughout the sampling period. Bottom water concentrations displayed a
seasonal trend: maximum MMHg concentrations were in June/July 2004, decreased to a
minimum in October 2004, and in May 2005 concentrations had begun to increase.
MMHg concentrations and MMHg as a percent of THg in surface sediment (0-2 cm)
also followed this trend. Bottom water dissolved oxygen and temperature displayed
inverse relationships with bottom water MMHg concentrations. This correlation between
dissolved oxygen and MMHg is typical for low-oxygen waters, but the relationship
between temperature and MMHg is relatively unique. A possible explanation is that
warmer summer temperatures inhibited bacterial methylation. Stratification intensity
(quantified as N2) was strongly correlated with bottom water MMHg concentrations,
indicating either increased methylation at the pycnocline or that the pycnocline inhibited
vertical mixing, thus limiting MMHg to the bottom water. Benthic flux estimations
indicate that sediment release of MMHg could be a significant source of MMHg to
bottom water. The presence of an oxygenated layer in the surface sediment could have
played a role in inhibiting MMHg flux during oxic conditions; a decrease in the
thickness of this layer under hypoxic conditions likely allowed MMHg to diffuse into the
bottom water. Dissolved oxygen seemed to play an important role in controlling
sediment MMHg concentrations with highest methylation rates in sediment under
hypoxic water. Overall, sites closest to the Mississippi River mouth displayed the highest MMHg concentrations. Further research will need to be done in this area to fully
characterize the relationship between biogeochemical parameters and MMHg
concentrations.
