Traces and shards of self-injury: Strange accounting with “Author X”
No full textIn this strange account autoethnography, three or four authors explore their lived experiences with self-injury. Strange accounting is both a post-modern style of text, and a method for keeping identities concealed when risks and secrets are in play. Author X, a post-modern place-keeper for an anonymous author who may or may not have contributed to this manuscript, introduces a new dimension and layer of concealment. With Author X in-play and under erasure, the reader will never be sure if there were three or four authors on this manuscript. Through strange accounting, a post-structuralist/postmodernist frame will be applied to understanding the self-injury experience. We frame self-injury as a social practice and, for some, an everyday norm, while remaining acutely aware of the stigma surrounding the topic of self-injury. Each of us, coupled with Author X, provide the others cover to trace stories of self-injury through the literature, our flesh, and our lives
A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
Astonishing comics: a disability studies perspective on x-men comics
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Letras/Inglês e Literatura Correspondente, Florianópolis, 2013Stan Lee co-created in 1963 the X-Men; comics characters who in consequence of developing super-powers at puberty due to natural genetic evolution suffer society?s prejudice. In their analysis of the X-Men Trilogy X-Men (Bryan Singer 2000); X2: X-Men United (Bryan Singer 2003); and X-Men: the Last Stand (Brett Ratner 2006); through a Disability Studies perspective Michael M. Chemers (2004), Ramona Ilea (2009), Martin Mantle (2007), and Jennifer Rinaldi (2008) argue that mutants can be understood as social characterizations of disability. This investigation studies whether this affirmation also holds true for mutants depicted in X-Men comics. I will analyze the comics storylines God Loves, Man Kills (Marvel Graphic Novel # 05) and Gifted (Astonishing X-Men # 01 - 06) ? on which X2: X-Men United and X-Men: the Last Stand were based respectively. Stan Lee foi o co-criador, em 1964, dos X-Men, personagens de histórias em quadrinhos os quais, em conseqüência de desenvolverem super-poderes na puberdade, são alvos do preconceito da sociedade. Ao analisar a Trilogia dos filmes dos X-Men - X-Men (Bryan Singer 2000); X2: X-Men United (Bryan Singer 2003); e X-Men: The Last Stand (Brett Ratner 2006); a partir de uma perspective de Estudos sobre Deficiência. Michael M. Chemers (2004), Ramona Ilea (2009), Martin Mantle (2007), e Jennifer Rinaldi (2008) argumentam que os mutantes podem ser compreendidos como caracterizações sociais de deficiência. Este estudo investiga se esta afirmação também é válida para os mutantes presentes nas histórias em quadrinhos dos X-Men. As linhas narrativas a serem analisadas são: God Loves, Man Kills (Marvel Graphic Novel 05) e Gifted (Astonishing X-Men # 01 - 06); nas quais foram baseados X2: X-Men United e X-Men: the Last Stand respectivamente
Exploring the apparent properties and Q-markers for quality control of Cornus officinalis
No full textCornus officinalis Siebold & Zucc. has a high nutritious value and is widely used in food fields. To distinguish the quality of cornus in different areas, this research provided a new strategy for comprehensively evaluating cornus. As a result, 12 iridoid glycosides and 7 polyphenols were identified and quantified by UHPLC-Q-TOF/MS in 13 batches of samples from five different origins. Chromaticity analysis pointed out that pelargonidin-3-O-galactoside, total iridoids, and total polyphenols performed high relation with 1365*. Antioxidant activity and inhibition of α-glucosidase effect correlated with the chemical analysis suggested that iridoid glycosides and
polyphenols should represent bioactivity of total extracts. Among these compounds, loganic acid, 7-ketologanin, cornuside I, and pelargonidin-3-O-glucoside were regarded as quality markers of cornus, which displayed the highest correlation with appearance. Above all, this paper contributed to establishing standards of external character and internal components for quality control of cornus

Enhanced colour encoding of materials discrimination information for multiple view dual-energy x-ray imaging
No full textThis thesis reports an investigation into dual-energy X-ray discrimination techniques. These techniques are designed to provide colour-coded materials discrimination information in a sequence of perspective images exhibiting sequential parallax. The methods developed are combined with a novel 3D imaging technique employing depth from motion or kinetic depth effect (KDE). This technique when applied to X-ray images is termed KDEX imaging and was developed previously by the university team for luggage screening applications at security checkpoints. A primary motivation for this research is that the dual-energy X-ray techniques, which are routinely incorporated into ‘standard’ 2D luggage scanners, provide relatively crude materials discrimination information. In this work it was critical that robust materials discrimination and colour encoding process was implemented as the sequential parallax exhibited by the KDEX imagery may introduce colour changes, due to the different X-ray beam paths associated with each perspective image. Any introduction of ‘colour noise’ into the resultant image sequences could affect the perception of depth and hinder the ongoing assessment of the potential utility of the dual-energy KDEX technique. Two dual-energy discrimination methods have been developed, termed K-II and W-E respectively. Employing the total amount of attenuation measured at each energy level and the weight fraction of layered structures, a combination of the K-II and the W-E techniques enables the computation and extraction of a target objects’ effective atomic number (Zeff) and its surface density (ρS) in the presence of masking layers
Relations between x-ray timing features and spectral parameters of galactic black hole x-ray binaries
No full textWe present a study of correlations between spectral and timing parameters for a sample of black hole X-ray binary candidates. Data are taken from GX
339-4, H 1743-322, and XTE J1650-500, as the Rossi X-ray Timing Explorer
(RXTE) observed complete outbursts of these sources. In our study we investigate outbursts that happened before the end of 2009 to make use of the high-energy coverage of the HEXTE detector and select observations that
show a certain type of quasi-periodic oscillations (type-C QPOs). The spectral parameters are derived using the empirical convolution model simpl to model the Comptonized component of the emission together with a disc blackbody for the emission of the accretion disc. Additional spectral features, namely a reflection component, a high-energy cut-off, and excess emission at 6.4 keV, are taken into account. Our investigations confirm the known positive
correlation between photon index and centroid frequency of the QPOs and reveal an anti-correlation between the fraction of up-scattered photons and the QPO frequency. We show that both correlations behave as expected in the “sombrero”
geometry. Furthermore, we find that during outburst decay the correlation between photon index and QPO frequency follow a general track, independent of individual outbursts

‘The Churchillian Paradigm and the “Other British Isles”: An Examination of Second World War Remembrance in Man, Orkney, and Jersey’
No full textThis dissertation studies Second World War ‘sites of memory’ in the islands of Jersey, Orkney and the Isle of Man, to determine if each island celebrates the war’s events as Britain does, or if they have charted their own mnemonic course. It builds on the work of Angus Calder, Malcolm Smith, and Mark Connelly, who have explored how popular conception of the Second World War in Britain has been structured around a certain set of commemorative motifs, most of which centre on Winston Churchill and the events of 1940. The British war narrative is now commonly referred to as the ‘Churchillian paradigm’ or ‘finest-hour myth’, and continues to be the driving force in commemoration and memorialization on the British mainland. The three islands in this study are culturally and historically distinct from Britain, and each has strong notions of its own ‘island identity’. Each also possesses a tangential and divisive domestic experience of war, one which is often minimized in the iconography of the Churchillian paradigm. Jersey was occupied by Nazi Germany from 1940 to 1945, Orkney was home to several thousand Italian POWs who built important infrastructure in the island, and the Isle of Man was home to 14,000 German, Finnish, Japanese, and Italian internees in what one critic has called ‘a bespattered page’ in the nation’s history. By examining ‘sites of memory’— museums, heritage sites, commemorations, celebrations, philately, and use of public space—this dissertation shows that each island simultaneously accepts and rejects elements of the finest-hour myth in their collective memory. Each island displays its unique (though often quite negative) heritage in order to differentiate itself from Britain, while at the same time allowing them, at certain events, to participate in celebration of Britain’s ‘greatest victory’. In this way, islands’ use ‘Britishness’ pragmatically, by basking in traditionally ‘British’ commemorative tropes, while at the same time deepening their own cultural and historical sovereignty
