Mycologg: a new accelerated test method for wood durability above ground
If not properly handled, selected and protected, wood will be degraded by bacteria, fungi and also insects. In order to ensure service life, durability tests are needed. Most accelerated laboratory tests on wood durability are focused either on fungi attacks or the uptake of moisture. Accelerated field tests in ground contact are of limited use since they could be difficult to reproduce and are sensitive to the characteristics of the soil in which the wood is placed. In addition, the results cannot be directly transferred to wood in use above ground because such wood is subjected to different set of conditions. The Mycologg is a new accelerated test method for estimating the durability of wood in above ground applications. The Mycologg allows the test panels to be subjected to the discolouring fungi and different RH (relative humidity) cycles simultaneously. Every 30 min, the temperature, the RH, and the moisture content in each test panel are measured and saved in special software. This allows for a constant update of the moisture patterns during a fungi attack. A trial was made with Scots pine (Pinus sylvestris) heartwood samples, where fungal growth after 6, 8 and 10 weeks in the Mycologg were compared to weather exposure of duplicate samples after 12, 16, and 26 months. The results showed that 10 weeks into the Mycologg accelerated test method corresponds well to real-time weather exposure with respect to fungal discolouration.

Gender, Strategy and Career Narratives
So far we have emphasised that organisational change cannot simply be understood as the product of the impersonal working out of rational economic processes. We have demonstrated the embodied character of current changes, emphasising that individuals within organisations are not passive in the (re)making of their workplaces. In the remainder of this book we seek to extend this analysis by focusing on the subjective dimensions of organisational membership, in order to show how the sorts of identity, value, aspiration and attitude that respondents hold towards their participation in their organisation help to clarify their actions within the organisation itself.
