Bordered Pit Imaging
2012 - IRG/WP 12-10773
New findings about bordered pits will be presented using the latest microscopy techniques. Three-dimensional imagery at the nanolevel is used, and short 3-D movies will shown as part of the discussion on this topic to reveal new features that have not previously been reported in pits. The implications for both microorganism penetration through lignified cells as well as preservative penetration i...

Bending Properties of FRT OSB
2012 - IRG/WP 12-40600
Fire retardant treated (FRT) oriented strandboard (OSB) and plywood of different widths were tested in static bending to determine width effects. Results were consistent with previous width effect studies and showed that increasing specimen width results in a decrease in sample MOR properties among all the sample groups tested in this study. Increasing sample width for OSB samples leads to more ...

Assessment of decay risk of airborne wood-decay fungi
2012 - IRG/WP 12-10787
The decay risk of airborne wood-decay fungi was investigated by using an air sampler. Japanese cedar disks measuring about 8 cm in diameter and 3 mm in thickness with moisture content at about 100 % were placed in a “BIOSAMP” air sampler and exposed to 1000 liters of air. Air sampling was carried out from June to September at the same sampling site in Tsukuba, Japan. The exposed disks were the...

Extractives in Norwegian-Grown and North American-Grown Western Redcedar and Their Relation to Durability
2012 - IRG/WP 12-10762
The extractives responsible for the natural durability of western redcedar (WRC) are not well understood. Recent work by the Norwegian Institute of Wood Technology and the Norwegian Forest and Landscape Institute has evaluated the natural durability of Norwegian wood species and reference species, including Norwegian-grown WRC and North American-grown WRC, in a series of decay tests. The availabil...

Preference of Reticulitermes flavipes (Kollar) for Southern Pine Blue-Stained Sapwood from Beetle-Killed Trees
2012 - IRG/WP 12-10763
Bark beetles and their associated Ophiostomatiod fungi are the major pests of pine forests in the southeastern USA, and termites are the major insect decomposers of dead trees and wood products in the southeastern USA. While both are the principal destructive insects of southern pine trees and southern pine lumber, respectively, no relationship between the two has apparently been reported in the ...

Above Ground Field Evaluation and GC-MS Analysis of Naturally Durable Wood Species
2012 - IRG/WP 12-10764
Nine wood species are being evaluated in above ground field studies in Mississippi and Wisconsin. Candidate naturally durable wood (NDW) species are being rated at yearly intervals for resistance to decay, cupping, and checking. Field ratings after 12 months exposure are presented. To date, Paulownia tomentosa (PAW) and southern yellow pine (SYP) are least durable and cedars are the most durable i...

Eastern redcedar included sapwood: Resistance to mold and termites under laboratory conditions
2012 - IRG/WP 12-10765
The heartwood of eastern redcedar (Juniperus virginiana) frequently contains areas of light-colored wood. This “included sapwood” is considered to be a defect by some manufacturers. In this study, sapwood, included sapwood and heartwood samples from five eastern redcedar trees were exposed to mold fungi or to subterranean termites in a no-choice feeding test. Extractives content was also measu...

Preliminary laboratory and field evaluation on the performance of Rubbermite as a graded physical barrier against subterranean termite species in Australia
2012 - IRG/WP 12-10766
This paper describes the performance of Rubbermite as a potential graded particle barrier against two subterranean termite species of Coptotermes in laboratory and field test. The results of these bioassays suggest that Rubbermite is a viable control option against Coptotermes species in Australia, particularly against Coptotermes acinaciformis (Froggatt) and Coptotermes lacteus (Froggatt). Rubber...

In-situ experimental treatment and consolidation of degraded timber elements from a XIX century building
2012 - IRG/WP 12-10767
This paper presents the in situ experimental conservation work performed on three timber structural elements from a XIX century building: two floor beams and one roof beam. The palace was built in 1877 in the centre of Lisbon initially with residential purposes. It has four floors, with timber structural horizontal elements, stairs and roof beams (generally of Pinus sylvestris L.). The exterior wa...

Preliminary laboratory bioassay to evaluate engineered Fibre-boards against subterranean termites C. acinaciformis (Isoptera: Rhinotermitidae)
2012 - IRG/WP 12-10768
In Australia, laboratory bioassays with subterranean termites typically contain groups of workers and soldiers in a substrate of moist mound material. This termite substrate may affect termite consumption, and the test materials create a favorable termite condition for the test. The main purpose of this test is to examine the effect of a melamine formaldehyde treatment of wood panels to evaluate t...
