Detection of feeding behaviour of termites using AE monitoring
1991 - IRG/WP 1514
Using acoustic emission (AE) monitoring, the feeding activity of the termite inhabiting a wood specimen was investigated. The amplitude and the rate of AE from the specimen of Coptotermes formosanus Shiraki was larger than that of Reticulitermes speratus Kolbe…

Non-destructive detection of the presence and behaviour patterns of wood-destroying insects
1988 - IRG/WP 2302
…the automatic recognition of the presence and of specific behaviour patterns of wood-boring insects, is introduced. From a wood sample, a mixture of noise and action induced substratum vibrations is picked up, amplified, filtered and translated into a sequence of computer-readable numbers which are passed to a…

The influence of formulation on the behaviour of LOSP's during industrial impregnation of spruce
1986 - IRG/WP 3387
Evidence is presented that the comparative behaviour of two LOSP formulations during impregnation treatment of spruce cannot be predicted purely on the basis of their physical characteristics (viscosity, surface tension and contact angle) nor on the extent of their 'passive'…

The growth and behaviour of Australian isolates of dry rot fungi, mainly Serpula lacrymans (Schum. ex Fr.) S.F. Gray. A comparision with the world literature
1983 - IRG/WP 1190
In Australia Serpula lacrymans occupies a rather unique environment, being restricted to growth within basal regions of buildings containing masonry. Its rate of timber attack in these situations appears to be far faster than that experienced in other parts of…

Mineral-wood composites with improved fire properties and durability prepared through MgCO3-based mineralization
2025 - IRG/WP 25-30823
…Mineralisation with the novel method improves the fire behaviour of Norway spruce (Picea abies) extending the time to ignition by more than 50% compared to the native wood. The total heat release in the first 600 seconds of the test (THR600s), the fire growth rate index (FIGRA) and the total smoke production are…

…models thus rely on accurate predictive models of moisture behaviour. However, capturing the complexities of free water movement in real-world scenarios – where environmental factors such as rainfall and humidity vary unpredictably – remains a major challenge. Numerical approaches, particularly diffusion-based…
