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

Deploying an everyday life approach, this article focuses on the kindergarten meal, defined as a space in which humans, materials and discursive elements interact. The article identifies and discusses two co-existing perspectives on the everyday meals that emphasise children as future beings and here-and-now beings. Through the concepts of smoothing and striation the paper discusses how these perspectives produce different mechanisms of regulation and agency, and position the eaters differently. The paper emphasises kindergarten mealtime as an ambiguous space that does not offer simple discussions about good and bad meal situations. The paper thereby adds to the existing literature within children’s geographies which emphasise interactional, relational and material aspects of children’s lives. It does so by revisiting some concepts, striation and smoothing, that has been used to explore children’s spaces and child–adult relations, but argue that these concepts describe ambivalent and complex processes in children’s and adult’s everyday lives.  相似文献

The recent financial and economic crisis had substantial but spatially differentiated impacts on growth. However, there is still a lot left to be understood about the local aspects of the crisis. One of these aspects is its socio-economic consequences. This paper investigates local socio-economic change to Danish towns from 2008 to 2013, with a focus on the impact of local labour market (LLM) structures on change. Socio-economic change in towns is measured both directly as mean income and employment growth, and indirectly as population and human capital growth. The paper relies on micro-data and uses robust regression to generate results. Several findings are presented, but the two main conclusions are: first, the LLM structures of towns still influence local socio-economic development; and, second, towns experience better socio-economic development if they are in close proximity to a larger labour market and/or have a large ratio of commuters in the working population.  相似文献
