Minimum standards for habitability in emergency housing
2015 - IRG/WP 15-50312
In this study we evaluated the properties of a prefabricated HOUSING prototype based on a 64mm thick "Structural Insulated Panel" (SIP; hereinafter SIP64), built by two OSB panels bonded with a two component polyurethane adhesive to a high density expanded polystyrene core. This panel was manufactured as a main element for walls in the construction of emergency housing. The thermal insulation of t...

Decay resistance of wood treated with bio-friendly preservative systems
2016 - IRG/WP 16-30698
Due to more restrictive toxicological requirements and increased ecological awareness of consumers, wood preservatives containing biocides are no longer desired on the market. Therefore, research on new environmentally friendly formulations is of great importance. One of the possible solutions is to develop new preservatives based on natural substances, which are harmless to humans, animals and th...

Fungistatic activity of quinolizidine and bisquinolizidine alkaloids against A. niger
2016 - IRG/WP 16-30699
In order to determine the relation between the structural properties and fungistatic activity of quinolizidine and bisquinolizidine alkaloids, the bioactive derivatives of cytisine, sparteine and lupanine were tested for the inhibitory activity against the microfungus causing mould growth phenomenon (Aspergillus niger van Tieghem ATCC 6275). The compounds tested were screened for antifungal prope...

Bio-friendly wood protection systems - resistance to mould and blue-stain fungi
2017 - IRG/WP 17-30713
With stricter restrictions on the use of biocides and increasing environmental awareness there is a pronounced need for effective bio-friendly protection systems in the wood preservative and wood coating industry. One of the possible pathways is to exploit and utilize natural substances with active biological effects. Silanes, caffeine, natural oils and potassium carbonate were chosen as compounds...
