Ten Year Performance Evaluation of a Field-Scale Zero-Valent Iron Permeable Reactive Barrier Installed to Remediate Trichloroethene Contaminated Groundwater

The Monkstown Fe0 PRB, Europe’s oldest commercially installed PRB, had been treating trichloroethene (TCE) contaminated groundwater for about 10 years on the Nortel Network site in Northern Ireland when cores were collected in December, 2006. Groundwater data from 2001-2006 indicated that TCE is being remediated to below detection limits as the contaminated groundwater flows through the PRB, Ca and Fe carbonates, crystalline and amorphous FeS, and Fe (oxy)hydroxides precipitates are present in the Fe0 filing material within the PRB. A greater variety of minerals are associated with a 1 cm thick slightly cemented crust at the entrance of the Fe0 section of the reactive vessel and the discontinuous cemented Fe0 material directly below it. Also, a greater presence of microbial communities occurred in the upper portion of the PRB compared to the lower section which might be due to less favourable conditions (i.e. high pH, low oxygen) for microbial growth in the lower section of the PRB. Visual estimation suggests that the Fe0 filings in the effluent section of the PRB have life-span of 10+ years compared to the Fe0 filings in the thin influent section of the PRB which may have a life span of only ~2-5 more years. Multi-tracer tests indicated that preferential pathways have formed in this PRB over the 10 years of operation.

Crossing the threshold: exile and literature in "El Canto del peregrino" (1999) by Angelina Muñiz-Huberman

This paper analyses the relation between exile and literature in Angelina Muñiz-Huberman’s work El canto del peregrino. In this collection of essays, the Spanish-Mexican writer, member of the second generation of Spanish Republican exiles in Mexico, outlines a poetics of exile. From the outset, the relation between exile and literature is presented in terms of identity: while defining exile as “literary form”, the book tends to prefer a metaphorical concept of exile over ‘merely’ historical or referential approaches to it. More in particular, this paper will examine how the author constructs an identity of ‘exiled writer’ based on the close association between exile and literature on the one hand, and on the view of exile as ‘home’ or ‘dwelling’, on the other hand. A second point of interest concerns the discursive impact of this literary and metaphorical concept of exile and the author’s personal experience. A brief analysis of the essayist’s discursive voice and her writing practice shows how Muñiz-Huberman gives shape to an intrinsically complex and paradoxical view on exile.

Ten years of protein kinase B signalling: a hard Akt to follow

It is ten years since the publication of three papers describing the cloning of a new proto-oncogene serine/threonine kinase termed protein kinase B (PKB)/Akt. Key roles for this protein kinase in cellular processes such as glucose metabolism, cell proliferation, apoptosis, transcription and cell migration are now well established. The explosion of publications involving PKB/Akt in the past three years emphasizes the high level of current interest in this signalling molecule. This review focuses on tracing the characterization of this kinase, through the elucidation of its mechanism of regulation, to its role in regulating physiological and pathophysiological processes,to our current understanding of the biology of PKB/Akt, and prospects for the future.

National Identity and National Unity in Contemporary East Timorese Literature

Beginning with a panoramic analysis of the role played by East Timorese poets in the struggle for liberation from Portuguese and Indonesian colonial rule, this article examines the extent to which an East Timorese national identity and unity repeatedly featured in the poetry of the 1970s and 80s are represented in contemporary Timorese literary production. By reading the work of the novelist Luís Cardoso, and the poets Abé Barreto and Celso Oliveira, the article also assesses whether the independent nation envisioned earlier by those such as Borja da Costa, Fernando Sylvan and Xanana Gusmão, has been realised. In doing so, critical attention is brought to bear on the intimate relationship between the specific material and political circumstances of East Timor and the literature produced in colonial and postcolonial moments in the nation’s history.

'Fairy Tale and Folklore in the Nineteenth Century', Blackwell Literature Compass, 6.3 (April 2009) 785-98

Fairies and fairy tales continue to intrigue both academic and popular audiences. This article, while exploring the diverse approaches of recent scholars in this field, also raises disciplinary questions. Should the study of folklore and of the literary fairy tale be seen as separate research areas, one the preserve of the cultural historian and folklorist, the other the remit of the literary scholar? Can we even make a clear distinction in the nineteenth century between authored, literary fairy tales and orally collected supernatural folktales? If it is reductive to assume that the fairy tale can always be classified (and potentially dismissed) as children's literature, how might recent trends in Victorian studies suggest new ways of seeing and teaching the genre? Discussing the fairy tale in the context of debates over orality and authenticity, literature and science, all of these questions will be examined below.
