A ducted wind turbine simulation model for building simulation

Power production is shifting away from centralized generation plants to production of heat and power at the point of demand. A technology that may play a part in this shift is the ducted wind turbine (DWT). The emergence of small building integrated micro turbines opens up the possibility of utilizing the differential pressures occurring around buildings for local power production. This paper describes work to develop and test a simple mathematical model of a ducted wind turbine and its integration within a building simulation tool. A case study in which the simulation model will be used to analyse of the likely power output from a building incorporating ducted wind turbines within the façade is also presented

Myanmar: The Key Link between South Asia and Southeast Asia

This paper examines the road and railway links in Myanmar connecting northeast India on the one side with the rest of Southeast Asia on the other. It also discusses the importance of new deep-sea ports in creating alternative shipping routes, essential for Myanmar's international links. It also reviews the country's external trade patterns, and analyzes issues related to trade facilitation, exchange rate policy, financial sector reform, and private sector development. The extent to which these gaps can be addressed will depend on the costs and benefits. South Asia-Southeast Asia connectivity can only be accomplished if Myanmar improves the hard and soft infrastructure aspects of connectivity

Meeting the audience challenge in the 'Age of Participation'

This paper explores the nature of a 'participatory museum experience' targeted at twenty-first century core audiences. It highlights the holistic nature of the museum visit; emphasises the importance of matching lifestyle expectations; argues for the central role of social interaction; prioritises the process of learning over outcomes; and both defines participatory exhibits and provides a preliminary typology. It concludes with a brief discussion of the root and branch transformation of museum structures implied by a participatory, social interaction-based approach

The authority of next-of-kin in explicit and presumed consent systems for deceased organ donation: an analysis of 54 nations

Background. The degree of involvement by the next-of-kin in deceased organ procurement worldwide is unclear. We investigated the next-of-kin’s authority in the procure-ment process in nations with either explicit or presumed consent. Methods. We collected data from 54 nations, 25 with presumed consent and 29 with explicit consent. We char-acterized the authority of the next-of-kin in the decision to donate deceased organs. Specifically, we examined whether the next-of-kin’s consent to procure organs was always required and whether the next-of-kin were able to veto procurement when the deceased had expressed a wish to donate. Results. The next-of-kin are involved in the organ procure-ment process in most nations regardless of the consent principle and whether the wishes of the deceased to be a donor were expressed or unknown. Nineteen of the 25 nations with presumed consent provide a method for individuals to express a wish to be a donor. However, health professionals in only four of these nations responded that they do not override a deceased’s expressed wish because of a family’s objection. Similarly, health profes-sionals in only four of the 29 nations with explicit consent proceed with a deceased’s pre-existing wish to be a donor and do not require next-of-kin’s consent, but caveats still remain for when this is done. Conclusions. The next-of-kin have a considerable influ-ence on the organ procurement process in both presumed and explicit consent nations
