When exposed to moisture, wood undergoes swelling and is susceptible to fungal degradation. Chemical modification via oligomeric lactic acid (OLA) treatment has been found to be a promising environmentally friendly solution to this disadvantage. In this study, wood was impregnated with OLA and then variously heat treated to polymerize the OLA in situ. The effect of curing temperature and time on OLA polymerization has been determined chemically. Dimensional stability was examined by water immersion and hygroscopicity measurements and biological decay resistance also evaluated. OLA impregnation followed by heat treatment enhanced wood properties. OLA cure at 160 °C for 48 h resulted in treated wood with greater dimensional stability and biological resistance.

Hay-making structures are part of the agricultural landscape of meadows and pastures. Hay meadows are still used and found all over Europe, but their distribution patterns as well as their characteristics and regional features depend on geographical area, climate, culture, and intensity of agriculture. Intensively used hay meadows are the most dominant, using heavy machinery to store hay mostly as rounded or square bales. Traditional hay-making structures represent structures or constructions, used to quickly dry freshly cut fodder and to protect it from humidity. The ‘ancient’ forms of traditional hay-making structures are becoming a relic, due to mechanisation and the use of new technologies. Both the need for drying hay and the traditional methods for doing so were similar across Europe. Our study of hay-making structures focuses on their current state, their development and history, current use and cultural values in various European countries. Regarding the construction and use of hay-making structures, we have distinguished three different types, which correlate to natural and regional conditions: (1) temporary hay racks of various shapes; (2) hay barracks, a special type of shelters for storing hay and (3) different types of permanent construction and buildings for drying and storing hay. Hay-making structures have been mostly preserved in connection with traditional agricultural landscapes, and particularly in the more remote regions or where associated with strong cultural identity.

The “Arctic peas” project Climate changes expected in the near future will result in higher temperatures and longer growing season at high latitudes. This might open up for possibilities for pea production in Arctic and northern areas, and the need for cultivars more adapted to northern conditions is likely to increase. At NordGen - a common genebank for all the Nordic countries - a large number of Nordic pea accessions are conserved, including both cultivars, landraces and breeding material. Does this material hold keys to the future? The ongoing Nordic cooperation research project «Arctic peas» aims to identify germplasm of peas well adapted either for breeding or immediate cultivation in the Arctic/Nordic regions. The project evaluates important traits in 50 selected accessions from NordGen in field trials at four contrasting Nordic locations, at latitudes ranging from 55° to 69° N (see map). Among the evaluated traits are flowering time, maturation time and yield, as well as protein content. Will the genetic material show different expressions at locations with clear distinction in daylength, temperature and climate? The project also aims to increase the knowledge and use of the Nordic pea accessions conserved at NordGen, and strengthen the collaboration between companies, organizations and researchers in the Nordic countries.
