Reticulitermes lucifugus Rossi, and its damages in Turkey
1982 - IRG/WP 1152
The moist-wood termite, Reticulitermes lucifugus Rossi, is generally observed on the wood material which has a direct contact with the soil as trunks and fence stakes. It was reported to be found in some provinces in Turkey. The termite has been seen in these areas so far at the endemic level, but any considerable damage or epidemy has not yet been reported. Considerable damages were observed on t...

Poplar wood and its damages in Iran
1987 - IRG/WP 1332
In Iran poplar planting has been used for many centuries ago specially in regions without forests. It had rural uses in ancient time, but recently many fast growing poplar species have been planted and many hybrids also have been planted; the following species had been cultivated widely in Iran: Populus nigra L. var. italica, Populus alba L., Populus caspica Bornm, Populus deltoides L., Populus X....

Severe decay damages of bridges made of ekki (Lophira alata) wood known as a durable species
2000 - IRG/WP 00-10383
Bridges made of ekki (azobe, bongossi, Lophira alata Banks et Gaertn.) timbers were severely decayed only 10 years after the construction possibly caused from no maintenance for the periods. The reason of no maintenance is due to the misunderstandings on wood durability against wood-decaying fungi. Some civil-engineers and architectures understand "durable species" means "absolutely decay-durable ...

Detection and estimation of Hylotrupes bajulus L. wood damages by ultrasonics
1990 - IRG/WP 2350
To evaluate the validity of the ultrasonic application in the detection and evaluation of wood damages produced by Hylotrupes bajulus L. larvae, some laboratory tests were made with small wood samples. The pulse through transmission method was used. The transit time of ultrasonic pulses in transversal sections, radial and tangential, of the samples was measured. The increment of the transit time o...
The evaluation of a survey of dry rot damages in Japan
1983 - IRG/WP 1179
The damage of wooden houses from Serpula lacrymans has increased in Japan, particularly in the northern area, Hokkaido Prefecture (See Figure 1). The weather conditions in Asahikawa have been recorded. The data obtained from the survey carried out over the five years from 1975 to 1980 were previously reported to the 5th International Biodeterioration Symposium which was held in Aberdeen, Scotland ...
Repairs of dry rot damages. A follow-up survey
1989 - IRG/WP 1400
The success of repairs of dry rot (Serpula lacrymans) damage in small houses was studied by means of a questionnaire, interviews and inspections. The research material consisted of 92 buildings in the first follow-up survey and of 71 of those 92 buildings in the second survey 6 years later. In 55 buildings the damages had been repaired once and at that time the harmfulness of dry rot fungus was kn...
Northern oak wood and its damages in Iran
1988 - IRG/WP 1377
The Northern oak species of Iran designated Quercus castaneaefolia C.A.M. is distributed widely in caspian littoral. In natural conditions (healthy) has favourable quality and it is used mostly in rural construtions, sleepers, parquets, cross arms for electric and communication poles, it is used also indoor and window construction, benches and finally veneer. This wood in the case of sleepers and ...

Fungal damages in Norwegian massive timber elements – causes and measures
2019 - IRG/WP 19-40879
Massive wood elements are relatively new in Norway but the use is growing quickly, primarily the use of cross-laminated timber (CLT). Moisture performance of massive timber elements has been examined by some researchers, but more knowledge is needed. There is uncertainty regarding the need for vapour barriers or retarders in roof assemblies, and for practical reasons buildings are rarely assembled...

Physical barriers against marine borers based on synthetic polymers
2020 - IRG/WP 20-30754
Currently in Spain there are no chemical treatments that are really effective against attacks of marine bores in civil constructions within more or less permanent contact with seawater. On the other hand there are also no physical barriers that allow easy placement or execution, and much less offer a minimum guarantee of performance in the medium or long term. In fact, in these recent years there ...
