St. Serf's Church Tower, Dunning, Perthshire: Data Structure Report

This report describes excavations undertaken as part of the SERF project. A small trench was excavated along the north wall of the tower of St Serf’s Church, Dunning. The tower was shown to be of the same 12th-century date of construction as the church, as it was bonded into the nave in its lower courses. Part of the north wall of the tower re-used an earlier structure as a foundation, providing rare evidence for a pre-12th century stone building. An earlier burial running under this foundation shows earlier activity on a different alignment, presumably dating to the early medieval period. Later medieval burials were also found. Details of the construction of the medieval church were uncovered

A theoretical model of a new electrostatic transducer incorporating fluidic amplification

This article concerns the design of a new electrostatic transducer whose backplate consists of a series of drilled pipes. A new one-dimensional model is derived which considers the interaction of the membrane with the air load, the air cavities, and the drilled pipes in the backplate. Dynamic equations for the impedance in each component of the device are calculated analytically and connected using interface conditions of continuity of pressure and radiation conditions into the air load. The model is able to produce solutions to the mechanical impedance of the device and the displacement of the membrane as a function of the device's design parameters. Model results for the output pressure compare well with previous experimental data. The inverse problem of retrieving the design parameters for a desired output is discussed

A New Jerusalem ‘at the ends of the earth’: interpreting Charles Thomas’s excavations at Iona Abbey 1956-63

Iona was a major European intellectual and artistic centre during the seventh to ninth centuries, with outstanding illustrated manuscripts, sculpture and religious writings produced there, despite its apparently peripheral location ‘at the ends of the earth’. Recent theological discourse has emphasised the leading role of Iona, and particularly its ninth abbot, Adomnán, in developing the metaphor of the earthly monastery as a mirror of heavenly Jerusalem, allowing us to suggest a new appreciation of the innovative monastic layout at Iona and its influence on other monasteries in northern Britain. The authors contend that the unique paved roadway and the schematic layout of the early church, shrine chapel and free-standing crosses were intended to evoke Jerusalem, and that the journey to the sacred heart of the site mirrored a pilgrim’s journey to the tomb of Christ. The key to this transformative understanding is Charles Thomas’s 1956–63 campaign of excavations on Iona, which this article is publishing for the first time. These excavations were influential in the history of early Christian archaeology in Britain as they helped to form many of Thomas’s ideas, later expressed in a series of influential books. They also revealed important new information on the layout and function of the monastic complex, and produced some unique metalwork and glass artefacts that considerably expand our knowledge of activities on the site. This article collates this new information with a re-assessment of the evidence from a large series of other excavations on Iona, and relates the results to recent explorations at other Insular monastic sites
