The remains of Henry V's flagship, the Grace Dieu, currently lie buried within the inter-tidal sediments of the River Hamble (S. England). Previous archaeological investigations have been hindered by difficult excavation conditions resulting in a poor understanding of the dimensions, shape and degradation state of the hull's deeper structure. This study therefore aimed to image, characterize and reconstruct the buried remains of this vessel using a high-resolution 3D acoustic sub-bottom Chirp system with RTK-GPS positioning capability. The accurate navigation and high-resolution data that were acquired enabled the construction of a full 3D image of the site that not only identified the remains of the wooden hull, but also features buried within it. In addition, the degradation state of these buried wooden remains were investigated by calculating reflection coefficients while a hypothetical larger reconstruction of the Grace Dieu's hull was achieved, through the use of the ShipShape ship design software package. 相似文献

Several decades after the discovery of the spectacular Nahal Mishmar Hoard (a collection of cast metal goods, some quite ornate, found in a cave high in the cliffs of the Judean Desert) many important questions about Chalcolithic metallurgy in the southern Levant remain unanswered. What is the origin of the materials used? Where were the final goods produced and what were the dynamics of production? In fact, new questions have also arisen as recent discoveries force us to reconsider previous interpretations of Chalcolithic metallurgy and the societies within which it evolved. Such will be the focus of this paper. 相似文献

ABSTRACT Despite the enormous efforts made to civilize the Hawaiian, the Maori, the Samoan, and Fijian, Islanders have not forgotten all of their stories and in fact many Pacific peoples are in a position to recover much of the knowledge that sustained communities for thousands of years. There is hope in what we have done to reclaim our heritages—finding our voices in our languages, stories, and songs, our perspectives in our arts and literatures, our muscle and will in our own political advocacy and pursuit of our rights in courts and international arenas. There is need, however, for a new vision that reunites human beings with all of their relations in the world, a vision necessary to sustain a very difficult struggle. 相似文献

ABSTRACT The paper implements a methodology for assessing the regional impact of investment grants on foreign direct investment (FDI) location, taking data for U.K. regional policy over the period 1985–2005. Using a Generalized Methods of Moments estimator it finds that each £25 million of grant changes the regional location of about six inward FDI projects. On average, projects have 150 jobs and each job diverted costs £27,500 (1995 prices). It also finds that the size of the area designated for grants has a positive location effect. The effect is small in relation to the overall scale of FDI, which may explain the weak grant effect found in recent plant‐based location studies. 相似文献
