A deflection test for monitoring decay in miniature beams
1986 - IRG/WP 2269
A laboratory apparatus for assessing decay in small stakes is described. It involves the measurement of deflection in a static bending apparatus using a displacement transducer linked to a microcomputer. Measurements are non-destructive, rapid, accurate and automatic and decay can be assessed repeatedly over long time periods....

Three dimensional computer representations of growth of microbial populations in wood
1984 - IRG/WP 1243
Creosoted distribution poles inoculated with either Lentinus lepideus, biological control organisms including Triochoderma or combinations of both were extensively sampled to monitor the spread of organisms. A computer program which enabled the results to be portrayed in a three dimensional graphic form was developed and is illustrated. Results showed that computer mapping of this type usefully en...

New conception for shortering the duration of fungitoxic test of wood preservatives. Part 2: Computer-assisted miniaturisation of wood specimens
1994 - IRG/WP 94-20052
The mass loss of wood used as a criterion in the standarised agar-block method of evaluation of toxic value of preservatives depends upon the relationship between volume of specimens, their outspread planes and ratio of areas of particular anatomic sections. Upon the computer-assisted mathematical basis the dimensions of miniaturized specimens which make 1/2, 1/4, and 1/8 part of standarized ones ...

Computer-assisted ranking of potential biocontrol fungi based on data from laboratory screening trials
1993 - IRG/WP 93-10023
Forty two fungal isolates were screened for antibiotic activity. In these sceering tests inhibition of target wood decay fungi was expressed as a series of numerical scores for each isolate. These scores, along with values for 5 other charactetistics, were used to assess the isolates. Using selection indices, isolates were judged on the basis of all the characteristics combined and, ranked in orde...

Industrial fixation systems: key factors, limitations and optimisation through the use of computer simulation modelling. Discussion paper
1994 - IRG/WP 94-40026
This paper briefly describes four fixation operative in the Netherlands, namely: circulating and non-circulating steam fixation cylinders, steam fixation chambers and controlled climate rooms. The general limitations of industrial practice are reviewed against the background of established fixation theory. The controlling variables, both material and process-related, for fixation processing are sp...

Three-dimensional modeling of fumigant distribution in wood poles
1993 - IRG/WP 93-30025
The practice of using fumigants to control internal decay has been widely accepted in the United States and has shown to be effect in control internal decay in transmission poles and other large wood timbers. Mathematical models were developed to simulate the chloropicrin movement in utility poles after treatment. The simulation results indicated that treatment of utility poles, using either tradi...

Analysis of decay progress anisotropy by X-ray computer tomography
2012 - IRG/WP 12-20501
Wood has a serious handicap as structural materials that it is vulnerable to decay by fungi. A weather exposed bridge has a possibility of an abrupt fall down, and wooden houses with heavily decayed structural members are easily destroyed by large earthquakes. To avoid such damages, a new predicting method on the decay progress in timber structures, and also its strength losing behavior along with...

Observation of Boring Process of Larvae of the Bamboo Powder-post Beetle (Dinoderus minutus)
2014 - IRG/WP 14-10821
The bamboo powder-post beetle Dinoderus minutus is a major pest of felled bamboo in Japan. X-ray computer tomography (CT) was applied to non-destructively trace the movement of the larvae of this beetle inside the infested bamboo samples. The bamboo samples were prepared from pieces of the Japanese timber bamboo Phyllostachys bambusoides culms that were enclosed with adult D. minutus beetles for a...

Studying fungal growth using automated image analysis and computer simulations
2016 - IRG/WP 16-20590
Wooden materials are prone to fungal attack resulting in damage and economic losses. Therefore many efforts have been made to understand the degradation of wood and to avoid the adverse effect of fungi. Even though the extent of degradation of a material is inversely proportional to the extension of the fungi attacking it, most researchers focus mainly on the former, leaving the study of the latte...

Visualization of Feeding Process of Larvae of the Wood-boring Beetles Using X-ray Computer Tomography
2019 - IRG/WP 19-10953
X-ray computer tomography (CT) was applied to observe the movement of the larvae of the wood-boring beetles Lyctus brunneus, Lyctus africanus, and Heterobostrychus aequalis inside the infested wood specimens. The larvae bred with artificial diet were inserted into the hole of wood specimens of rubber wood Hevea spp. or Japanese oak Quercus crispula. The wood specimens with larvae were scanned usin...
