Any performance of the intercultural necessarily, and always, advances the question of the cultural since it involves the inter-action and interplay of unique and particular cultural performance styles and modes. Intercultural theatre, according to Pavis, is a hybrid theatrical form “drawing upon performance traditions traceable to distinct cultural areas. The hybridization is very often such that the original forms can no longer be distinguished.” The result of this collaboration of forms is, however, often not a ‘hybrid’ where cultural texts work cohesively and in unison to produce a harmonious mise en scene. Instead, intercultural performances are performances at the interstices and at the intersections of cultures. They raise problems of authorship, authority and performance unities and expose a sense of cultural foreignness. Consequently, intercultural performance can be said to be meta-theatre that queries the construction of culture since it places alongside performance traditions that confront.

Music, as performative unit, is a significant line of action by which the intercultural spectacle is constructed. Integral to Western theatre, and certainly more so in traditional Asian performance forms, the deliberate ‘fusion’ and ‘blending’ of musical styles in intercultural performances underscore not a harmony of diverse sounds but the possible dissonance and discordance already performed by the visual and verbal texts. The paper thus seeks to examine, in particular, the musical elements in intercultural performances such as Ong Keng Sen’s Lear (Theatreworks, 1999) and explore the ways in which music could possibly intensify the confrontation of performative texts resulting in a disruption of performance unities. When watching and listening to Lear, the question of the ‘local’ thus arises not merely with identification and alienation from what is seen but also what is familiar and foreign to one’s ears.

It is now widely accepted that intercellular communication can cause significant variations in cellular responses to genotoxic stress. The radiation-induced bystander effect is a prime example of this effect, where cells shielded from radiation exposure see a significant reduction in survival when cultured with irradiated cells. However, there is a lack of robust, quantitative models of this effect which are widely applicable. In this work, we present a novel mathematical model of radiation-induced intercellular signalling which incorporates signal production and response kinetics together with the effects of direct irradiation, and test it against published data sets, including modulated field exposures. This model suggests that these so-called "bystander" effects play a significant role in determining cellular survival, even in directly irradiated populations, meaning that the inclusion of intercellular communication may be essential to produce robust models of radio-biological outcomes in clinically relevant in vivo situations.

With emission legislation becoming ever more stringent, automotive companies are forced to invest heavily into solutions to meet the targets set. To date the most effective way of treating emissions is through the use of catalytic converters. Current testing methods of catalytic converters whether being tested on a vehicle or in a lab reactor can be expensive and offer little information about what is occurring within the catalyst. It is for this reason and the increased price of precious metal that kinetic modelling has become a popular alternative to experimental testing.

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).

The H-2-assisted hydrocarbon selective catalytic reduction (HC-SCR) of NO, was investigated using fast transient kinetic analysis coupled with isotopically labelled (NO)-N-15. This allowed monitoring of the evolution of products and reactants during switches of H-2 in and out of the SCR reaction mix. The results obtained with a time resolution of less than 1 s showed that the effect on the reaction of the removal or addition of H-2 was essentially instantaneous. This is consistent with the view that H-2 has a direct chemical effect on the reaction mechanism rather than a secondary one through the formation of "active" Ag clusters. The effect of H-2 partial pressure was investigated at 245 degrees C, it was found that increasing partial pressure of H-2 resulted in increasing conversion of NO and octane. It was also found that the addition of H-2 at 245 degrees C had different effects on the product distribution depending on its partial pressure. The change of the nitrogen balance over time during switches in and out of hydrogen showed that significant quantities of N-containing species were stored when hydrogen was introduced to the system. The positive nitrogen balance on removal of H-2 from the gas phase showed that these stored species continued to react after removal of hydrogen to form N-2. (c) 2006 Elsevier Inc.

This chapter analyses Marvell’s linguistic ingenuity as exemplified by his Latin poetic corpus. Here, it is argued, a pseudo Lucretian sensitivity to the parallelism between the structure of Latin words and the structure of the world co-exists with a linguistic methodology that is essentially Marinesque. Close examination of the Latin poems as a whole assesses the nature and significance of etymological play, paronomasia, puns on juxtaposed Latin words, on place names, and on personal names. It is suggested that such devices demonstrate ways in which the neo-Latin poetic text can serve both as a linguistic microcosm of the literary contexts in which they are employed, and as a re-invention of the artifice, extravagant conceits, and baroque wit of Marinism. The result is a neo-Latin ‘echoing song’ that is both intra- and intertextual. Through bilingual punning and phonological wit Marvell plays with a classical language only to demonstrate its transformative potential. The chapter concludes by offering a new reading of Hortus in relation to the garden sections of Marino’s L’Adone, in which an extravagantly luscious setting confounds the senses and is mirrored linguistically by word-clusters and labyrinthine punning.

Boundary layer transition estimation and modelling is essential for the design of many engineering products across many industries. In this paper, the Reynolds-averaged Navier–Stokes are solved in conjunction with three additional transport equations to model and predict boundary layer transition. The transition model (referred to as the kTkT–kLkL–ωω model) is based on the kk–ωω framework with an additional transport equation to incorporate the effects low-frequency flow oscillations in the form of a laminar kinetic energy (kLkL). Firstly, a number of rectifications are made to the original kTkT–kLkL–ωω framework in order to ensure an appropriate response to the free-stream turbulence level and to improve near wall predictions. Additionally, the model is extended to incorporate the capability to model transition due to surface irregularities in the form of backward-facing steps with maximum non-dimensional step sizes of approximately 1.5 times the local displacement thickness of the boundary layer where the irregularity is located (i.e k/δ∗⪅1.5k/δ∗⪅1.5) at upstream turbulence intensities in the range 0.01<Tu(%)<0.80.01<Tu(%)<0.8. A novel function is proposed to incorporate transition sensitivity due to aft-facing steps. This paper details the rationale behind the development of this new function and demonstrates its suitability for transition onset estimation on a flat plate at zero pressure gradient.
