Archaeological wood is usually severely degraded. The Norwegian Viking Age Oseberg find exemplifies problems arising due to past conservation treatments and the need for new types of preservatives. Phenol formaldehyde (PF) has been investigated as a consolidant for alum‐treated wood. X‐ray tomography has revealed that it is possible to obtain a porous structure inside the wood, ensuring ethical acceptability by allowing re‐treatment. In order to understand the curing mechanics, the kinetics of the initial condensation reaction were elucidated at room temperature. It was found that a second‐order reaction using both phenol and formaldehyde concentrations is the most probable mechanism.  相似文献

  The discovery of female figurines at Brassempouy in the 1890's would launch more than a century of debate and interpretation concerning Paleolithic representations of women. The figurines emerged from the ground into a colonial intellectual and socio-political context nearly obsessed with matters of race. This early racial interpretive frame would only be replaced in the mid 20th century, when prehistorians turned to questions such as fertility and womanhood. The first figurines were discovered in 1892 under rather tortured circumstances in which their very ownership was the subject of a heated dispute between Edouard Piette and Emile Cartailhac. Their toxic relationship would lead Piette, in his subsequent excavations, to be extremely precise about issues of stratigraphic and spatial provenience. Piette's publications and archives enabled Henri Delporte to confirm the Gravettian attribution of the figurines and have allowed the present author to create a map of their spatial distribution within the site. Technological and microscopic analysis of the Brassempouy figurines resolves some lingering questions about the sex of certain of the figurines and suggests an original context of figurine fabrication and the abandonment of unsuccessful sculpting attempts.

Many postprocessual archaeologists have argued that active individuals make history. The apotheosis of the individual has been achieved under the rubric identity, the most pervasive theoretical term of the last few years. This focus obscures the fundamental idea that individuals do not exist in isolation. The relational concept of struggle will help us past this theoretical impasse. This concept has many components including real struggles in the past, our struggles to know the past, and using the past to struggle in the present. Our goal is to struggle past identity politics and the individual by focusing on peoples' real struggles in real cases.  相似文献
