Two Early Examples of Welsh English as a Marker of National Identity : leuan ap Hywel Swrdwal's Hymn to the Virgin and Shakespeare's Fluellen.

ISBN : 978-2-901737-81-0International audienceIn this paper we examine a number of linguistic traits in Ieuan ap Hywel Swrdwal's English-language poem entitled "Hymn to the Virgin" (circa. 1480). These are compared to similar features portrayed in the speech of captain Fluellen, on of the main characters in Shakespeare's play, Henry V (1599). While Swrdwal's poems in perhaps the first attested example where Welsh English characteristics are highlighted for nationalistic reasons, Shakespeare intention is clearly to caricature the Welsh accent in English for the pleasure of his audience. The approach used here is sociolinguistic and diachronic. The working hypothesis based on the principle that the English and Welsh languages have exercised mutual influence on each other since the two languages have been in contact, that is to say for well over a millennium. This linguistic interaction has provoked, and continues to provoke, significant changes that have altered Welsh English has well as the Welsh language itself. We thus have two highly symbolic examples of Welsh English, the first as viewed from the inside by a Welshman and the second as viewed from the outside by an Englishman. Both serve to demonstrate that the salient characteristics of Welsh English as it was spoken 400 to 500 years ago are no longer necessarily recognizable in the Welsh English speech today.Comparaison d'un certain nombre de traits linguistiques relevés dans le poème "Hymn to the virgin" de Ieuan ap Hywel Swrdwal (~1480). Ils sont comparés à des caractéristiques semblables présentes dans le discours du Capitaine Fluellen, un des personnages principaux de Henry V, pièce de Shakespeare (1599).

Inducing hardening and healability in poly(ethylene-co-acrylic acid) via blending with complementary low molecular weight additives

The design and synthesis of low molecular weight additives based on self-assembling nitroarylurea units, and their compatibility with poly(ethylene-co-acrylic acid) copolymers are reported. The self-assembly properties of the low molecular weight additives have been demonstrated in a series of gelation studies. Upon blending at low percentage weights (≤ 5%) with poly(ethylene-co-acrylic acid) the additives were capable of increasing the stress and strain to failure when compared to the parent copolymer. By varying the percentage weight of the additive as well as the type of additive the mechanical properties of poly(ethylene-co-acrylic acid) could be tailored. Finally, the healability characteristics of the blends were improved when compared to the original polymer via the introduction of a supramolecular ‘network within a network’

Synthesis and analysis of a healable, poly(propylene glycol)-based supramolecular network

An investigation into healable supramolecular networks based upon branched poly(propylene) (PPG) oligomers that feature nitroarylurea chain ends is reported. A one-pot reaction utilising bis(toluene-1,4-diisocyanate)-terminated poly(propyleneglycol) (Mn ~ 2300), a nitroarylurea recognition motif, and tris(2-aminoethyl)amine was used to synthesise several branched PPG-based oligomers. The degree of oligomerization/branching was systematically varied by changing the stoichiometry of the starting materials in this one-pot reaction. The branched oligomers thus generated self-assemble into supramolecular networks, aided by association of the nitroarylurea end groups, and from this study a material that is capable of healing at ambient temperatures was realised. The healable supramolecular material formed from these studies exhibited effective autonomous healing (80% with respect to ultimate stress) up to 6 weeks after defect formation. Furthermore, elastic recovery was observed (80% with respect to yield stress) over a period of 24 hours after the samples were elongated beyond the region of uniform strain (50%)

Mississippi Canyon 252 Incident NRDA Tier 1 for Deepwater Communities

The northern Gulf of Mexico (GOM) is geologically diverse basin, described as the most complex continental slope region in the world. Regional topography of the slope consists of basins, knolls, ridges, and mounds derived from the dynamic adjustments of salt and the introduction of large volumes of sediment over long time scales. More than 99% of the sea floor in the GOM consists of soft sediment made up of various mixtures of primarily silt and clay. These wide-spread soft bottom communities are described in reports from major MMS studies by Gallaway et al. (1998) and Rowe and Kennicutt (2009). Relative to soft bottoms, hard bottoms and their associated communities are relatively uncommon by are notable for their high biodiversity and complexity

Nitroarylurea-terminated supramolecular polymers that exhibit facile thermal repair and aqueous swelling-induced sealing of defects

Bi- and tri-armed polyethylene glycol units endcapped with nitroaryl urea units have been synthesised. These endcapped polymers are able to self-assemble via complementary supramolecular interactions, specifically urea-urea and nitro-urea hydrogen bonding, to afford materials with dramatically increased mechanical and thermal properties when compared to those of the uncapped polyethylene glycol precursors. Thin films of the capped polymeric systems are able to self-repair following defect creation. Control over the mechanical and thermal characteristics (in terms of bulk viscosity) of the self-assembled networks was achieved by varying the proportion of tri-armed to bi-armed self-assembly units included in the polymer. These systems demonstrate water absorption and swelling capabilities that are also controllable by varying the ratio of the two types of unit. These physical properties have been optimised to realise a secondary pathway to puncture-repair as a result of swelling on water contact

Brassica ASTRA: an integrated database for Brassica genomic research

Brassica ASTRA is a public database for genomic information on Brassica species. The database incorporates expressed sequences with Swiss-Prot and GenBank comparative sequence annotation as well as secondary Gene Ontology (GO) annotation derived from the comparison with Arabidopsis TAIR GO annotations. Simple sequence repeat molecular markers are identified within resident sequences and mapped onto the closely related Arabidopsis genome sequence. Bacterial artificial chromosome (BAC) end sequences derived from the Multinational Brassica Genome Project are also mapped onto the Arabidopsis genome sequence enabling users to identify candidate Brassica BACs corresponding to syntenic regions of Arabidopsis. This information is maintained in a MySQL database with a web interface providing the primary means of interrogation. The database is accessible at http://hornbill.cspp.latrobe.edu.au

SNPServer: a real-time SNP discovery tool

SNPServer is a real-time flexible tool for the discovery of SNPs (single nucleotide polymorphisms) within DNA sequence data. The program uses BLAST, to identify related sequences, and CAP3, to cluster and align these sequences. The alignments are parsed to the SNP discovery software autoSNP, a program that detects SNPs and insertion/deletion polymorphisms (indels). Alternatively, lists of related sequences or pre-assembled sequences may be entered for SNP discovery. SNPServer and autoSNP use redundancy to differentiate between candidate SNPs and sequence errors. For each candidate SNP, two measures of confidence are calculated, the redundancy of the polymorphism at a SNP locus and the co-segregation of the candidate SNP with other SNPs in the alignment. SNPServer is available at

The geochemistry of Atlantic hydrothermal particles

Particles were collected from the dilute portion of neutrally buoyant hydrothermal plumes from four Mid-Atlantic Ridge sites (MARK, 23°N; TAG, 26°N; Broken Spur, 29°N; Lucky Strike, 37°N). Comparison of data from proximal portions of the TAG (Atlantic) [German et al., 1991; this study] and North Cleft (Pacific) [Freely et al., 1994] plumes show that oxyanion (e.g., V) is more efficient at TAG, possibly due to a higher proportion of Fe removed as sulfides at North Cleft and/or the more vigorous mixing in the high energy TAG buoyant plume. Chalcophile elements (e.g., Cu) show two stage removal. They are precipitated as sulfides during initial mixing of vent fluids with seawater and are sedimented from the buoyant plume. In the dilute plume they are scavenged from seawater by Fe oxyhydroxides. The REE show continued scavenging in the neutrally buoyant plume and lower levels in 1993 samples compared to 1988 samples [German et al., 1990] suggesting that the amount of scavenging is related to particle recycling.Copyrighted by American Geophysical Union

Elevation as a proxy for mosquito-borne Zika virus transmission in the Americas.

INTRODUCTION: When Zika virus (ZIKV) first began its spread from Brazil to other parts of the Americas, national-level travel notices were issued, carrying with them significant economic consequences to affected countries. Although regions of some affected countries were likely unsuitable for mosquito-borne transmission of ZIKV, the absence of high quality, timely surveillance data made it difficult to confidently demarcate infection risk at a sub-national level. In the absence of reliable data on ZIKV activity, a pragmatic approach was needed to identify subnational geographic areas where the risk of ZIKV infection via mosquitoes was expected to be negligible. To address this urgent need, we evaluated elevation as a proxy for mosquito-borne ZIKV transmission. METHODS: For sixteen countries with local ZIKV transmission in the Americas, we analyzed (i) modelled occurrence of the primary vector for ZIKV, Aedes aegypti, (ii) human population counts, and (iii) reported historical dengue cases, specifically across 100-meter elevation levels between 1,500m and 2,500m. Specifically, we quantified land area, population size, and the number of observed dengue cases above each elevation level to identify a threshold where the predicted risks of encountering Ae. aegypti become negligible. RESULTS: Above 1,600m, less than 1% of each country's total land area was predicted to have Ae. aegypti occurrence. Above 1,900m, less than 1% of each country's resident population lived in areas where Ae. aegypti was predicted to occur. Across all 16 countries, 1.1% of historical dengue cases were reported above 2,000m. DISCUSSION: These results suggest low potential for mosquito-borne ZIKV transmission above 2,000m in the Americas. Although elevation is a crude predictor of environmental suitability for ZIKV transmission, its constancy made it a pragmatic input for policy decision-making during this public health emergency
