The Newport Ship is the most substantial late medieval vessel excavated and recovered in Britain in recent years. It was abandoned after extensive salvage, possibly following attempts at repairs to the hull. More than 23 m of the clinker‐built ship were recovered, along with significant artefact and environmental assemblages. Finds point to strong Iberian connections during the active life of the ship, which arrived in Newport in the Severn Estuary, after the spring of AD 1468. The dismantling and recovery of the ship has enabled detailed recording using innovative 3D digital techniques and approaches to hypothetical reconstruction. Publication includes a digital archive hosted by the Archaeological Data Service, a substantial report and this article.  相似文献

This study is based on the paleaopathology of leprosy on human skeletal remains and the detection of ancient Mycobacterium leprae DNA. Two cases of childhood leprosy were recognized. The first case was in a Roman necropolis at Martellona (Rome, Central Italy), dated to the 2nd to 3rd centuries ce . The skeleton of a child aged 4–5 years, from tomb 162, is the youngest individual in Italy from this time period, with the clear rhino‐maxillary syndrome and other bony changes indicative of leprosy. The second case from a burial at Kovuklukaya, in the Sinop region of Northern Turkey, was from the 8th to the 10th centuries, during the Byzantine era. The endocranium of a 4–5‐month‐old infant with new bone formation—an indication of chronic inflammation—was positive for M. leprae DNA. Infant and childhood leprosy is uncommon today, and there is a scarcity of information in the osteoarchaeological literature of leprosy in the past, especially in children. The significance of these cases is that it adds to an understanding of the history of the disease in the former Roman Empire. It is hoped that over time sufficient data can be obtained to understand the epidemiological dynamics and clinical evolution of leprosy from the ancient period until today.

Song of Songs is the love story of tha ages. It encompasses all the drama known of love, naturally and spiritually. In this writing is presented the controversy that preceded the canonization of the Song of Songs within Judaism and early Christianity. Presented is an overview of the vehicles that have been used in the exegeses of the Song of Songs as well as a discussion of the traditionally held allegorical interpretation of the Song. Within this writing there is also a discussion of the debate that still persists due to the view held by some scholars that the poetry of the Song is a translation of pagan litany when utilizing the Cult Theory. It is the intent of this writing to suggest an analogy between the Song of Songs and the book of Genesis, chapters two and three. In using the tool of analogy this writer discovered that there exists aspects of likeness, as well as that of contrast. The Song becomes, in a sense, a parable in which the allegorical interpretation of the Song is not considered in its traditional sense. Utilizing the Drama Theory, the principle characters in this consideration are the Shulamite woman, the Rustic lover, and the king. There are reflective qualities that exist in the Song of Song to Chapters two and three of Genesis. As noted by Francis Landy, ''The Song is a reflection on the story of the garden of Eden, using the same images of garden and trees…''.  相似文献

ABSTRACT

Literal biblical interpretation advocates the view that at the outset of the paradise story Adam and Eve were only banned to eat of the tree of knowledge. The present paper challenges this view through an economic, ra-tional choice interpretation and the application of a self-interested decision calculus (model of economic man). I mount the thesis that, on grounds of a rational choice reconstruction, Adam and Eve must have been implicitly banned from the outset not to eat of the tree of life, despite no explicit ban be-ing stated in Genesis. The paper argues for the validity and insightfulness of such a rational choice analysis of the paradise story, which considerably clari-fies the conceptual logic and structure of the Eden story.  相似文献

Deformation and focused fluid flow within a mineralized system are critical in the genesis of hydrothermal ore deposits. Dilation and integrated fluid flux due to coupled deformation and fluid flow in simple strike–slip fault geometries were examined using finite difference analysis in three dimensions. A series of generic fault bend and fault jog geometries consistent with those seen in the western Mount Isa Inlier were modelled in order to understand how fault geometry parameters influence the dilation and integrated fluid flux. Fault dip, fault width, bend/jog angle, and length were varied, and a cross-cutting fault and contrasting rock types were included. The results demonstrate that low fault dips, the presence of contrasts in rock type, and wide faults produce highest dilation and integrated fluid flux values. Increasing fault bend lengths and angles increases dilation and integrated fluid flux, but increasing fault jog length or angle has the opposite effect. There is minimal difference between the outputs from the releasing and restraining fault bend and jog geometries. Model characteristics producing greater fluid flows and/or gradients can be used in a predictive capacity in order to focus exploration on regions with more favorable fault geometries, provided that the mineralized rocks had Mohr–Coulomb rheologies similar to the ones used in the models.  相似文献

贾湖骨笛是迄今为止我国历史上最早、形态完整、现今仍可演奏的吹管乐器,是9000~7500年前中国古代科技文明最重要的实物载体之一。由于骨笛经历数千年的埋藏,出土时多数已经破损。如何对破损的贾湖骨笛进行精确复制,是学界急待解决的难题。我们巧妙地利用CT扫描、数据处理、三维模型重建、虚拟复原与激光快速成型技术,复原出与M494:2号骨笛实物十分接近复原品。这种利用计算机虚拟修复的思想与技术为破损贾湖骨笛的复原开辟了一条新的技术途径。  相似文献

Li, L.-Y., Zhang, X.-L., Yun, H. & Li, G.-X., October 2015. New occurrence of Cambroclavus absonus from the lowermost Cambrian of North China and its stratigraphical importance. Alcheringa 40, xxx–xxx. ISSN 0311-5518.

The problematic Small Shelly Fossil Cambroclavus absonus is described from the Xinji Formation in the Longxian area, which is located near the southwestern margin of the North China Platform. The Xinji Formation, the basal rock unit of the Cambrian in the studied area, yields an assemblage of skeletal fossils that share many common elements with contemporary faunas from South Australia. Sclerites of C. absonus reported herein represent the first occurrence of the species outside Australia, thus extending the palaeogeographic range of the taxon to northern China. To date, palaeogeographic occurrences of Cambroclavus sclerites are restricted to the Peri-Gondwana realm, including South China, Australia, Tarim, Kazakhstan, North China and Western Europe. These occurrences are divided into a Southern Group realm and Northern Group realm. Stratigraphically, Cambroclavus occurs mostly in Cambrian Stage 3 and has three occurrences in Stage 5, separated by Stage 4 in which Cambroclavus has not yet been found. The first appearance datum of Cambroclavus in Cambrian Stage 3 is of importance for regional and inter-regional correlations. In particular, the presence of Cambroclavus absonus in North China allows species-level correlation between North China and South Australia.

This study focuses on domes the ground plan of which, instead of the more common circular shape, is an oval, and aims at finding the minimally necessary uniform wall thickness for domes of different geometries loaded by their selfweight. The discrete element code 3DEC was applied because of its capability of simulating the collapse mechanisms of masonry structures. Results on the minimal wall thickness, corresponding masonry volume and failure mechanisms for different dome geometries are presented. Three ranges of the friction coefficient were found. For very low frictional resistance collapse happens with pure frictional sliding, for any arbitrarily large wall thickness. In the range of relatively high (i.e., realistic) friction coefficients the structure collapses without any sliding if the wall is not sufficiently thick, and in the observed range of the friction coefficient the necessary wall thickness is nearly insensitive to its value (collapse initiates with hinging cracks only). Between the two domains an intermediate behavior was found: combined cracking and sliding collapse modes occur for insufficient wall thickness, and the minimal thickness strongly depends on the friction coefficient. The critical and transitional friction coefficients separating the failure modes were determined for different eccentricities of the groundplan.  相似文献
