Direct measurement of fluid flow within wood
1986 - IRG/WP 2248
The problematics of fluid flow mechanism within wood using a permeability concept are highlighted, and the non-feasibility of a practical and versatile model is explained. An alternative method using a negative temperature coefficient thermistor to measure flow velocity directly is presented. The method has been verified in living trees and shows extreme sensitivity for flow above 1 meter/hour. Fo...

Temperature influence on the growing velocity and cellulolytic activities of Poria placenta strains from several locations
1986 - IRG/WP 2263
The differences observed on the FPRL 280 Poria Placenta strain at several Research European Laboratories for determining up the fungicide effectiveness of wood preservative has carry us to do a comparative study about the cellulolytic activity and growth velocity of each of this strains at different temperatures (22, 24 and 28°C). The results show significative differences when the temperature is...

Nondestructive Detection of Biodeterioration in Indonesian Traditional Wooden Construction of “Joglo”
2014 - IRG/WP 14-10834
To decide the repairing and reinforcement method for wooden constructions, it is necessary to get the enough and precise information on the status of the construction beforehand, especially the distribution and the degree of the biodeterioration, such as decay or insect attack (e.g. termite attack).
In this study, damage of biodeterioration to teak wood used in Indonesian traditional wooden const...
