An integrated approach to national marine resources development

A review is presented of the various marine resources and their potential, concerning fishing, aquaculture, transportation, pollution, hydrocarbons and solid minerals, renewable energy and ocean thermal energy conversion. Administrative problems confronting their rational management in Sri Lanka are examined, considering coastal area management and development, management issues, and alternatives

Topology and dynamics of the A-pillar vortex

The topology and dynamics of the flow bypassing an automobile A-pillar modeled by a 30° dihedron are investigated experimentally. The various components of the A-pillar flow are identified by means of low and high frequency particle image velocimetry. For each component, the time evolution of the position, displacement, vorticity magnitude, circulation, and fluctuating kinetic energy are analyzed along the A-pillar. More precisely, the flow by passing the A-pillar is composed of two vortex structures with different behaviors. The major structure grows in size, circulation magnitude, and total amount of fluctuating kinetic energy along the A-pillar, whereas the minor structure does not vary significantly. Finally, the displacement of the major structure is identified as a movement of precession and the influence of the A-pillar geometry is emphasized

Impact of the introduction of new vaccines and vaccine wastage rate on the cost-effectiveness of routine EPI: lessons from a descriptive study in a Cameroonian health district

The Expanded Program of Immunization (EPI) offers services to the population free of charge but these activities are costly with the greatest part being the cost of vaccines. In spite of the growing international solidarity towards funding for immunization, the growing objectives continue to outweigh the available resources. It is therefore crucial for any immunization system to seek greater efficiency so as to optimize the use of available means in a bid to ensure sustainability. It is in this light that we carried out this study which aims to assess the productive efficiency of routine EPI for children aged 0 - 11 months with respect to the fixed and outreach vaccine delivery strategies in Ngong health district. The study is descriptive and cross-sectional. Data were collected retrospectively for all 16 health centers of the district that offered EPI services during the period February - May 2009

Collective Intelligence, the Future of Internet and the IEML

Collective Intelligence, the book in French, that Pierre Levy wrote before the existence of the worldwide web, when only the Internet existed, it's a philosophical vision of the future, a philosophical vision of what could be a global civilization based on the digital and the general interconnection of all the computers. In the interview, Levy addresses the creation o the WWW by Tim Berners Lee as a form of collective intelligence. He then discusses Berners Lee's proposal for a reform of the WWW to avoid its confiscation by the big platforms, such as Google, Facebook, and Amazon. Then, he introduces his most recent project the IELM as a tool for semantic metadata and a code between the natural languages and the algorithms, and all the apparatus of computations
