nero- a post-maximum supernova radiation transport code

The interpretation of supernova (SN) spectra is essential for deriving SN ejecta properties such as density and composition, which in turn can tell us about their progenitors and the explosion mechanism. A very large number of atomic processes are important for spectrum formation. Several tools for calculating SN spectra exist, but they mainly focus on the very early or late epochs. The intermediate phase, which requires a non-local thermodynamic equilibrium (NLTE) treatment of radiation transport has rarely been studied. In this paper, we present a new SN radiation transport code, nero, which can look at those epochs. All the atomic processes are treated in full NLTE, under a steady-state assumption. This is a valid approach between roughly 50 and 500days after the explosion depending on SN type. This covers the post-maximum photospheric and the early and the intermediate nebular phase. As a test, we compare nero to the radiation transport code of Jerkstrand, Fransson & Kozma and to the nebular code of Mazzali et al. All three codes have been developed independently and a comparison provides a valuable opportunity to investigate their reliability. Currently, nero is one-dimensional and can be used for predicting spectra of synthetic explosion models or for deriving SN properties by spectral modelling. To demonstrate this, we study the spectra of the 'normal' Type Ia supernova (SN Ia) 2005cf between 50 and 350 days after the explosion and identify most of the common SN Ia line features at post-maximum epochs. © 2011 The Authors Monthly Notices of the Royal Astronomical Society © 2011 RAS.

‘5 ways to say your prayers’:The Art and Architecture of Curating People, Place and Creativity in a Post-Conflict Context. The Shed, Galway, Ireland 18th June – 23rd July 2013 Includes: 1. Co-Curation of Exhibition with Peter Mutschler, Director of PS² and 2. Morrow’s individual work as part of the exhibition, entitled ‘Departures & Arrivals: Academic Interactions with the Activities, Artists and Archive of PS² ’

This exhibition profiles the curatorial approach of PS² and the work of creative practitioners who have practiced alongside and with the organisation. PS² is a Belfast-based, voluntary arts organisation that initiates projects inside and outside its project space. It seeks to develop a socio-spatial practice that responds to the post-conflict context of Northern Ireland, with particular focus on active intervention and social interaction between local people, creative practitioners, multidisciplinary groups and theorists.
Morrow has collaborated with PS² since its inception in 2005, acting as curatorial advisor specifically on the projects that occur outside PS² . She regards her involvement as a parallel action to her pedagogical explorations within architectural education.

Morrow's personal contribution to the Exhibition aimed to:
-interrogate PS² spatial projects
-contextualise PS² curatorial practice
-open up the analytical framework and extend to similar local practices

The Shed, Galway, Ireland is a joint Galway City Arts and Harbour Company venture. The exhibition subsequently travelled to DarcSpace Gallery, Dublin (Sept 2013).

Serial chimerism analyses indicate that mixed haemopoietic chimerism influences the probability of graft rejection and disease recurrence following allogeneic stem cell transplantation (SCT) for severe aplastic anaemia (SAA): indication for routine assessment of chimerism post SCT for SAA

Ninety-one patients were studied serially for chimeric status following allogeneic stem cell transplantation (SCT) for severe aplastic anaemia (SAA) or Fanconi Anaemia (FA). Short tandem repeat polymerase chain reaction (STR-PCR) was used to stratify patients into five groups: (A) complete donor chimeras (n = 39), (B) transient mixed chimeras (n = 15) (C) stable mixed chimeras (n = 18), (D) progressive mixed chimeras (n = 14) (E) recipient chimeras with early graft rejection (n = 5). As serial sampling was not possible in Group E, serial chimerism results for 86 patients were available for analysis. The following factors were analysed for association with chimeric status: age, sex match, donor type, aetiology of aplasia, source of stem cells, number of cells engrafted, conditioning regimen, graft-versus-host disease (GvHD) prophylaxis, occurrence of acute and chronic GvHD and survival. Progressive mixed chimeras (PMCs) were at high risk of late graft rejection (n = 10, P <0.0001). Seven of these patients lost their graft during withdrawal of immunosuppressive therapy. STR-PCR indicated an inverse correlation between detection of recipient cells post-SCT and occurrence of acute GvHD (P = 0.008). PMC was a bad prognostic indicator of survival (P = 0.003). Monitoring of chimeric status during cyclosporin withdrawal may facilitate therapeutic intervention to prevent late graft rejection in patients transplanted for SAA.

From Frank Miller to Zack Snyder, and Return: Contemporary Superhero Comics and Post-Classical Hollywood

Film adaptations of superhero comic-books offer a particularly rich case study to analyse narrative strategies of contemporary Hollywood cinema. The serial structures adopted by the comics they are based on, as well as their use of the spectacular potential of the image, provide a successful model for current audiovisual productions. Without completely abandoning classical techniques, these adaptations try to find a new balance between narrative and digital phantasmagoria. This paper discusses some significant examples of this genre, including adaptations of classical DC and Marvel franchises and more recent series, as well as other comic-book influenced films such as The Matrix and Unbreakable.

Cannibale, Frigidaire, and the Multitude: Post-1977 Italian Comics through Radical Theory

A direct connection between comics and contemporary critical theory is to be found in the activity of the collective of artists who created "Cannibale" and "Frigidaire", the two most innovative Italian comics magazines of the late 1970s and early 1980s. The work of Andrea Pazienza, Filippo Scòzzari, Stefano Tamburini, Tanino Liberatore and Massimo Mattioli should be regarded as an expression of the radical movements from which Marxist Autonomist thinkers such as Antonio Negri, Franco ‘Bifo’ Berardi and Paolo Virno also emerged in the same period. As a consequence, the writings of the latter can be used to analyse the narrative and visual style, the recurring themes, and the editorial characteristics of the comics of the former. Moreover, an interesting parallel can also be drawn between the work of the most influential of these artists, Andrea Pazienza, and the thought of another prominent Italian philosopher, Giorgio Agamben, whose earliest books were published at that time too. The aim of this article is to show that the ideas of a number of the thinkers who have recently become internationally known as representatives of radical Italian theory, are useful to understand the work of this group of comics authors.

Counter-Revolution by Ideology? Law and development's vision(s) for post-revolutionary Egypt

Law and development, as both movement and practice, has led a tumultuous life: a hurried zenith cut short by a fatal critique followed by an opportunistic resurrection. The name alone is su?cient to trigger a range of reactions, extending from the complimentary to the condemnatory. In this article I track law and development’s evolution via an examination of its role in the remodelling of Egyptian society in the post-Nasser era. While the 2011 revolution has encouraged institutions such as USAID to hasten their legal reform e?orts, I argue that these are more akin to counter-revolution by ideology than genuine revolution by law. Nevertheless, rather than relegate the movement to the annals of imperial intrigue, I conclude by proposing the use of legal pluralism to revive, and possibly ignite, law and development’s emancipatory potential.

Effect of post-weld-annealing on the tensile deformation characteristics of laser-welded NiTi thin foil

Laser welding is an important process for fabricating complex components involving NiTi shape memory
alloy. As welding is a thermal process, the amount of heat input and the rate of cooling have significant
impact on the microstructure and hence the resultant characteristics of NiTi. In this study, the effect of
laser welding and post-weld-annealing from 573 K to 1173 K on the thermal phase transformation behaviors,
tensile deformation and micro-hardness characteristics of the laser-welded NiTi thin foils were investigated.
It was found that the as-welded sample exhibited inferior super-elasticity compared to the base
material, and the super-elasticity could be partially restored by annealing at 573 K. On the other hand,
annealing of the weldment above the recrystallization temperature would lower the super-elasticity.

Effect of post-weld heat-treatment on the oxide film and corrosion behaviour of laser-welded shape memory NiTi wires

Post-weld heat-treatment (PWHT) was applied to NiTi weldments to improve the corrosion behaviour by modifying the microstructure and surface composition. The surface oxide film on the weldments is principally TiO2, together with some Ti, TiO, and Ti2O3. The surface Ti/Ni ratio of the weldments after PWHT is increased. The oxide film formed in Hanks’ solution is thicker on the weldments after PWHT. The pitting resistance of the weldments is increased by PWHT. The galvanic effect in the weldments is very small. The weldment with PWHT at 350 °C shows the best corrosion resistance among other heat-treated weldments in this study.

The Revival of Private Property and Its Limits in Post-Mao China

This monograph examines the nature and significance of the re-emergence of private property in rapidly changing post-Mao China.

In examining this issue, the study explores a key dichotomy in Chinese law, that is, ‘public versus private’, and examines the manner in which the Chinese define ownership. The study stresses the importance of lack of clarity in the boundaries between the public and the private in property rights.

While there is a limited move towards the recognition of private property in real estate in contemporary China, this analysis also shows that ownership in the law, and ownership as understood and practised socially, often diverge significantly.

From the Qing dynasty reforms of the late nineteenth century onwards, ‘modernist’ law and entrenched social practice have often opposed each other. In contrast to the official, and indeed legal, support for unitary and exclusive property rights, the reality of the property regime has been a fragmentation of property rights. ‘Modern’ conceptions and theories of property rights emerged in the context of nation-building from the late Qing onwards, and unitary and exclusive property rights were considered as ‘badges’ of modernity.

These conceptions and theories served (and still serve) the purposes of control and governance but were, and still are, often resisted in social practice and popular thinking, leading to alienation and conflict. As a result, analysis of the nature and the social and political implications of re-emerging private property rights provides important insights for our understanding of the changing nature of modern China.
