1. Biological growth on mineral façades
Sammanfattning : During the last years there has been reported considerable and rapid contamination on newly built rendered façades in Sweden due to biological growth. The problem is believed to occur mostly on façades of render applied on thermal insulation, but apart from this it is difficult to find clear relationships indication which façades might be infected.

2. Cellulose-based electrical insulation materials : Dielectric and mechanical properties
Sammanfattning : The reliability of the generation and distribution of electricity is highly dependent on electrical insulation and is essential for the prosperity of our society and a ubiquitous part of our everyday life. The present study shows how some important material properties affect the electrical properties of cellulose-based electrical insulation systems which are used together with mineral oil in high-voltage transformers.

3. Impact of moisture on long term performance of insulating products based on stone wool
Sammanfattning : Demands for energy have been increasing in the whole world. According to higher consumption, the price of energy rises yearly too. This evokes usage of insulating products in a wider range. LÄS MER
4. High Voltage DC-biased Oil Type Medium Frequency Transformer; A Green Solution for Series DC Wind Park Concept
Sammanfattning : The electric energy generated by remote offshore wind parks is transported to the consumers using high voltage submarine cables. On the generation site, such transmissions are realized today by collecting the energy produced by several wind turbines in a bulky and expensive transformer placed on a dedicated platform. LÄS MER
5. On the improvement of low frequency sound insulation in wooden buildings
Sammanfattning : Wooden multi-family residential houses continue to gain in popularity. Compared to concrete, wooden constructions have low mass and are subject to relatively poor sound insulation at low frequencies. LÄS MER
