Biodeterioration of cultural monuments in the Republic of Macedonia
2008 - IRG/WP 08-10640
Research on the biodeterioration of the cultural heritage in the Republic of Macedonia was conducted from 2004 to 2006, one month per year. The expertise was focused on the biodeterioration caused by wood-inhabiting fungi and moulds. A total of 38 cultural monuments, including 37 monasteries and churches and one fortress, were inspected in the areas of the towns of Skopje, Ohrid, Demir Hisar, Deba...

Qualitative - Quantitative Analysis of Wood-Inhabiting Fungi in External Wooden Structures of the Latvian Cultural Heritage
2010 - IRG/WP 10-10728
The frequency and diversity of wood inhabiting fungi in the exterior wood were established in the Araishi lake fortress, the Lielvarde wooden castle, the Latvian Ethnographic Open-Air Museum, Riga, and twelve wooden heritage objects in the Eastern part of Latvia (Latgale). The inspected wooden structures of the external woodwork included windows, stairs, walls, floorings, roofs, fences, and benche...

Hydrothermal modification for upgrading the durability properties of soft deciduous wood
2010 - IRG/WP 10-40494
To extend the application potentialities of soft deciduous wood, upgrading the durability properties, hydrothermal modification (HTM) of aspen alder and birch wood was investigated. The treatment was conducted in a multifunctional laboratory device WTT. In the previous cases it has been found that the treatment at 160oC improves the durability insufficiently. The modification at 180oC ensured a hi...

Exterior birch plywood: potentiality of the thermo-hydro treatment
2016 - IRG/WP 16-40743
It has been found in the present study that, in laboratory fungi tests after leaching with water (EN 84), exterior birch (Betula spp.) plywood, as birch solid wood, is subjected to degradation by rot fungi. This limits the use of such plywood outdoors or in building structures in high humidity conditions. The possibility to improve the birch plywood fungal resistance was investigated in two ways: ...

Exploration of waterlogged piles and wooden constructions of Riga Dome Cathedral
2017 - IRG/WP 17-10901
The Riga Dome Cathedral’s waterlogged wood piles and the roofs and tower's wooden structures were investigated, the extent of biological damage was evaluated, and the wood rot fungi and insects were identified. The pile wood’s component composition and elemental composition were analysed; the wood structure damage by erosion bacteria was microscopically determined. In the roofs and tower ...

Optimized composition of alkyd emulsion with nanoparticles of iron oxide for enhancing protection of thermally modified wood
2022 - IRG/WP 22-40940
Thermal treatment is acknowledged as an environmentally friendly method to improve durability of wood and some of its properties, such as biological resistance, dimensional stability, reduced hygroscopy. Despite these improvements, when used outdoors, also thermally treated wood is subjected to the action of environmental factors, like solar radiation, moisture, precipitations, temperature, etc., ...
