Sediment constituents and quartz in the sand-sized fraction, West Florida slope and Mississippi Fan sediments

The interval between 488.2 and 513.7 m below seafloor at Deep Sea Drilling Project (DSDP) Site 615 is interpreted as a single carbonate gravity-flow deposit. The deposit has characteristics of both a debris flow and a high-density turbidity current. Comparison of the sedimentary constituents in 15 samples from this site with samples from 26 core tops from the upper West Florida continental slope and eastern Mississippi Fan shows many similarities. Shallow-water indicators, such as mollusk and echinoid fragments, occur in both suites of samples. The West Florida continental margin, therefore, is a potential provenance area. The Yucatan slope is also a possible source, but data from it are limited. The recognition of carbonate gravity-flow deposits intercalated within the Mississippi Fan refines our understanding of Pleistocene sedimentation within the Gulf basin. Deposition in the deep Gulf is dominated by the construction of the Mississippi Fan. However, this marine terrigenous depocenter is located between two large carbonate depocenters, the West Florida continental margin on the east and the Yucatan peninsula on the southwest. Periodically, the carbonate slope in these two regions fails, injecting carbonate gravity flows into the accreting terrigenous deep-sea fan.

NS1 protein secretion during the acute phase of West Nile virus infection

The West Nile virus (WNV) nonstructural protein NS1 is a protein of unknown function that is found within, associated with, and secreted from infected cells. We systematically investigated the kinetics of NS1 secretion in vitro and in vivo to determine the potential use of this protein as a diagnostic marker and to analyze NS1 secretion in relation to the infection cycle. A sensitive antigen capture enzyme-linked immunosorbent assay (ELISA) for detection of WNW NS1 (polyclonal-ACE) was developed, as well as a capture ELISA for the specific detection of NS1 multimers (4G4-ACE). The 4G4-ACE detected native NS1 antigens at high sensitivity, whereas the polyclonal-ACE had a higher specificity for recombinant forms of the protein. Applying these assays we found that only a small fraction of intracellular NS1 is secreted and that secretion of NS1 in tissue culture is delayed compared to the release of virus particles. In experimentally infected hamsters, NS1 was detected in the serum between days 3 and 8 postinfection, peaking on day 5, the day prior to the onset of clinical disease; immunoglobulin M (IgM) antibodies were detected at low levels on day 5 postinfection. Although real-time PCR gave the earliest indication of infection (day 1), the diagnostic performance of the 4G4-ACE was comparable to that of real-time PCR during the time period when NS1 was secreted. Moreover, the 4G4-ACE was found to be superior in performance to both the IgM and plaque assays during this time period, suggesting that NS1 is a viable early diagnostic marker of WNV infection.

West Midlands English:Birmingham and the Black Country

This volume focuses on the closely allied yet differing linguistic varieties of Birmingham and its immediate neighbour to the west, the industrial heartland of the Black Country. Both of these areas rose to economic prominence and success during the Industrial Revolution, and both have suffered economically and socially as a result of post-war industrial decline. The industrial heritage of both areas has meant that tight knit and socially homogeneous individual areas in each region have demonstrated in many respects little linguistic change over time, and have continued to exhibit linguistic features, especially morphological constructions, peculiar to these areas or now restricted to these areas. At the same time, immigration from other areas of the British Isles over time, from Commonwealth countries and later from EU member states, together with increased social mobility, have meant that newly developing structures and more widespread UK linguistic phenomena have spread into these varieties. This volume provides a clear description of the structure of the linguistic varieties spoken in the two areas. Following the structure of the Dialects of English volumes, it provides: •A comprehensive overview of the phonological, grammatical and lexical structure of both varieties, as well as similarities between the two varieties and distinguishing features •Thorough discussion of the historical and social factors behind the development of the varieties and the stigma attached to these varieties •Discussion of the unusual situation of the Black Country as an area undefined in geographical and administrative terms, existing only in the imagination •Examples of the variety from native speakers of differing ethnicities, ages and genders •An annotated bibliography for further consultation

West Midlands English:Birmingham and the Black Country

This chapter provides an overview, discussing firstly the boundaries of the West Midlands area today within which Birmingham and the Black Country are situated, taking account of how they have changed across time. It includes a section on the demographic make-up of the region across time, before moving on to consider issues relating to language, culture and identity in section 1.5 on the theoretical underpinnings of the research upon which much of this book is based, particularly in relation to Chapters 2, 3 and 4 is also included. Section 1.6 then considers issues relating to research design, and the different methodologies adopted in research design and data collection and analysis by three separate projects which inform the chapters of this book. The Geographical Limits of the west Midlands: Where does it begin and where does it end? The Local Government Boundary Commission for England (2010: http://www.lgbce.org.uk/) gives the geographical range of the west Midlands as the five counties of Herefordshire, Shropshire, Staffordshire, Warwickshire and Worcestershire. The boundaries of these five shire counties date back to at least the twelfth century, being ancient subdivisions established by the Normans for administration purposes after the 1066 conquest. The shire counties were, in most cases, based on earlier Anglo-Saxon divisions. In 1974, as a result of population density concentrated in parts of the shire counties, a sixth county, that of the West Midlands, was carved out from parts of the three shire counties of Staffordshire, Warwickshire and Worcestershire.
