Mount Nemrut is a 2,206 m high mountain located in Adiyaman, Turkey. A number of monumental statues, a 50-m high tumulus, and a lion horoscope were constructed at the top of the mountain by King Antiochos I (69–36 bc) of the Commagene Kingdom. The site was included in the UNESCO World Heritage List in 1987 due to its unique character. However, the limestone statues located on both the east and the west terraces of the site are getting deteriorated. This study investigates the weathering of the limestone at Mount Nemrut based on field and laboratory studies. It is found that the dissolution occurs along microcracks developed in the limestone during geological time. It is more pronounced in the east terrace where freezing-thawing cycles are more than the west terrace. Furthermore, dissolution is more effective for the faces of the statues exposed to direct atmospheric contact. Due to harsh atmospheric conditions with dominant wetting-drying and freezing-thawing processes at the site, it is recommended that direct rain and snow contact with the statues should be minimized.  相似文献

The Upper Palaeolithic skeleton from Vado all'Arancio (Italy), dated to about 11,330 BP, exhibits a severe ankle fracture healed with residual deformation. Following recovery, this young hunter‐gatherer continued to walk for an extended period of time, albeit in a mechanically altered manner. While right‐left differences in external lower limb bone measurements are relatively low, biomechanical analysis of femur and tibia indicates unusually pronounced asymmetry in all cross‐sectional measures of diaphyseal strength. Asymmetry results primarily from normal side endosteal hypertrophy, and not from hypotrophy of the injured limb, suggesting that this individual resumed active life following recovery. This pattern of asymmetry underscores the role of physical activity in maintaining bone mass. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

Today, distal humeral fractures occur most frequently in children and adolescents, and are usually the result of a fall onto extended arms, or less often on flexed elbows. Trauma to the distal humerus at the physis and epiphyses often produces non‐displaced or mildly displaced fractures that are difficult to recognize radiographically. To help identify these types of injuries, clinicians have developed two measurement techniques that are applied to the X‐rays of the injured bones. In a preliminary attempt to assess the usefulness of these measurement techniques for recognizing trauma in archaeological skeletal remains, 25 humeri from two Ontario ossuary samples were submitted to radiography. Clinical data on distal humeral fractures, their incidence, and mechanisms of injury were also used to interpret the lifestyles and cultural activities of the aboriginal individuals under study. While only one healed fracture was suspected after gross observation, a total of four fractures were ultimately identified using the two measurements, the humerotangential‐angle (HTA) and the anterior hunieral line (AHL). Our results provide indirect, but telling, evidence of accidental childhood injuries to distal humerus in an archaeological population. Copyright © 2001 John Wiley & Sons, Ltd.  相似文献
