This paper demonstrates the combined use of X-ray computed tomography (XCT), energy dispersive X-ray spectroscopy (EDX) and X-ray fluorescence (XRF) to evaluate the conservational history of the dentary (lower jaw) of Megalosaurus bucklandii Mantell, 1827, the first scientifically described dinosaur. Previous analysis using XCT revealed that the specimen had undergone at least two phases of repair...
Of key importance to any cultural institution is the practice of conservation, the method by which specimens at risk of severe degradation or destruction are treated to ensure that they survive into the future. However, surface inspection is often insufficient to properly inform conservators of the best treatment approach, and where there is little to no record of the conservational history of an...
In 1503, two ships part of Vasco da Gamas second armada to India were lost at sea. Archaeologists followed the historical trail that led them to the wreck site in Ghubbat ar Rahib Bay off Al Hallaniyah Island, Oman. The excavation found over 2800 artefacts including a ships bell and a concretion of silver coins. In this study the use of X-ray Computed Tomography (XCT) is outlined and how its exploitation...
Experimental investigations into the collapse of granular columns are presented with dimensional results of the final deposit obtained using a 3D laser scanner. The high accuracy measurement method has found that the final pile radius is not only dependent on the aspect ratio of the initial geometry as previously thought, but also the initial column radius and hence the ratio of column radius to particle...
