Predicting toxic gas concentrations resulting from enclosure fires using local equivalence ratio concept linked to fire field models

A practical CFD method is presented in this study to predict the generation of toxic gases in enclosure fires. The model makes use of local combustion conditions to determine the yield of carbon monoxide, carbon dioxide, hydrocarbon, soot and oxygen. The local conditions used in the determination of these species are the local equivalence ratio (LER) and the local temperature. The heat released from combustion is calculated using the volumetric heat source model or the eddy dissipation model (EDM). The model is then used to simulate a range of reduced-scale and full-scale fire experiments. The model predictions for most of the predicted species are then shown to be in good agreement with the test results

'Re-using an existing wheel' developing data architecture for cooperating autonomous and semi-autonomous, agent-based web services

This short position paper considers issues in developing Data Architecture for the Internet of Things (IoT) through the medium of an exemplar project, Domain Expertise Capture in Authoring and Development ­Environments (DECADE). A brief discussion sets the background for IoT, and the development of the ­distinction between things and computers. The paper makes a strong argument to avoid reinvention of the wheel, and to reuse approaches to distributed heterogeneous data architectures and the lessons learned from that work, and apply them to this situation. DECADE requires an autonomous recording system, ­local data storage, semi-autonomous verification model, sign-off mechanism, qualitative and ­quantitative ­analysis ­carried out when and where required through web-service architecture, based on ontology and analytic agents, with a self-maintaining ontology model. To develop this, we describe a web-service ­architecture, ­combining a distributed data warehouse, web services for analysis agents, ontology agents and a ­verification engine, with a centrally verified outcome database maintained by certifying body for qualification/­professional status.

Local examination of skin diffusion using FTIR spectroscopic imaging and multivariate target factor analysis

In the context of trans-dermal drug delivery it is very important to have mechanistic insight into the barrier function of the skin's stratum corneum and the diffusion mechanisms of topically applied drugs. Currently spectroscopic imaging techniques are evolving which enable a spatial examination of various types of samples in a dynamic way. ATR-FTIR imaging opens up the possibility to monitor spatial diffusion profiles across the stratum corneum of a skin sample. Multivariate data analyses methods based on factor analysis are able to provide insight into the large amount of spectroscopically complex and highly overlapping signals generated. Multivariate target factor analysis was used for spectral resolution and local diffusion profiles with time through stratum corneum. A model drug, 4-cyanophenol in polyethylene glycol 600 and water was studied. Results indicate that the average diffusion profiles between spatially different locations show similar profiles despite the heterogeneous nature of the biological sample and the challenging experimental set-up.

Putting down routes: an examination of local government cultural policy shaping the development of heritage trails

This paper explores the significance of trails within local government cultural strategies by presenting the results of an audit of 1000 trails, content analysis of local cultural strategies and a series of interviews with local government cultural officers. It highlights the growing sophistication of trails as flexible and multi-faceted products promising an array of social, environmental, cultural and economic benefits. However, key issues emerge as challenges for local government cultural officers. These include the need for a realistic assessment of the relative importance of competing rationales, the design of methodologies to enable evidence-based policy making and more effective engagement with commercial organisations.

Sustainability and local tourism branding in England's South Downs

This paper reports on a stakeholder consultation exercise that examined the tourism industry's perception of developing a local tourism branding scheme within the South Downs' protected areas in south-east England. The research shows that such schemes could offer potential benefits that are recognisable by the tourism industry, while helping to meet the statutory aims of the protected area. The paper records the perceptions of small tourism businesses, their fears, awareness of tourism impacts, perceptions of sustainable tourism and of local branding, and key criteria connected to the future organisation of a local tourism branding scheme. The conclusion lists the recommendations for the implementation of a local branding scheme, including grassroots stakeholder consultation that encourages ownership and participation, institutional frameworks that support capacity-building and the importance of developing core values within a local brand.

Local public finance in Central and Eastern Europe: assessing the first decade

[Taken from book jacket] This book explores the system of financing local governments in selected countries of Central and Eastern Europe. Using evidence from the last two decades, the authors, experts on their particular countries, describe the development of the current local government finance system in each nation, and the major challenges and policy options they face. The contributions in this book provide comprehensive coverage of a transitional Europe that encompasses both modern local public finance theory and specific applications in the target countries.
