The alveolar bone condition of 34 pre-seventeenth century Solomon Island Polynesians aged 20–35 years was investigated from dental remains. The distance between the cementoenamel junction and the alveolar crest (CEJ-AC distance) was measured for six index teeth. The mean CEJ-AC measurements for each tooth, which ranged from 3.9 to 7.9 mm, greatly exceeded the distance of 2 mm frequently cited as representative of teeth supported by healthy bone. Many pathological bony defects were seen, suggestive of episodes of acute periodontitis with remissions to a quiescent phase.  相似文献

This article attempts to follow the tradition established by Hintze and Elias in comparing several aspects of representative institutions throughout medieval Europe. It uses numerous recent case studies and a new more detailed examination of the Low Country sources and it tries to take into account the criticisms levelled at the rather unsophisticated generalizations of earlier scholars. Attention is given to the structure of the institutions, their actual working and their functions.Comparisons are made whenever the available information permits, if possible by quantification, although our information is often too vague and incomplete to permit this. A number of ideal types are formulated as a working hypothesis for further investigation, based on the social structures within which these types of institutions functioned. The essential variables were the extent of urbanization in a particular territory, the form of government and the economic and juridical situation of the nobles and peasants.  相似文献

Seleucia Pieria: an ancient harbour submitted to two successive uplifts   总被引:1,自引:0,他引:1  
Historical sources ascribe the foundation of Seleucia (Seleukeia) Pieria to Seleucos I Nikator, shortly before the foundation of Antioch in the late 4th century BC. The Seleucia Pieria site seems however to have been inhabited earlier, perhaps from around 700 BC, possibly by a Greek population under an Assyrian ruler. The city became of considerable military importance during the wars between the Ptolemies and the Seleucids; it was occupied by the Romans in the 1st century BC, but had practically disappeared in the 6th century AD.
Geomorphological surveys in the area have revealed the existence of elevated marine notches and rims bioconstructed by vermetids, oysters and calcareous algae, which occasionally erode or intersect the archaeological sites, showing that two rapid land uplift movements, probably of seismic origin, took place during the late Holocene. The first movement, which occurred about 2500 ± 100 years bp, was the strongest one and caused a local vertical displacement of about 1.7 m, which may have severely affected the earlier Greek settlement. Though several earthquakes are reported to have occurred in the area during the following ten centuries, none of them seem to have been strong enough to cause significant vertical displacements. The second movement occurred around 1400 years bp, probably in May 526 AD, when a great earthquake followed by tsunami waves is known to have caused devastating damage in Antioch and Seleucia. According to geomorphological data supported by several radiocarbon dates, the earthquake was accompanied by a 0.7 to 0 8 m upheaval. This seismotectonic event also caused a rapid silting of the Seleucia Pieria closed harbour basin and entrances, thus preventing its further use.  相似文献
