There is no airport, no air access except for an occasional ship's helicopter and no sheltered anchorage. The nearest port is over 1,700 miles away--...
متن کاملA mathematical model of common-cold epidemics on Tristan da Cunha.
Records of seven common-cold outbreaks on the island of Tristan da Cunha are compared with the corresponding time courses given by the mathematical model of Kermack & McKendrick (1927) and with an alternative model that directly involves a constant average duration of individual infection. Using computer simulation techniques the latter model is shown to be preferred and is then closely matched...
متن کاملThe Geomagnetic Observatory on Tristan da Cunha: Setup, Operation and Experiences
