1. Thermo-electric temperature measurements in friction stir welding : Towards feedback control of temperature
Abstract : Friction Stir Welding has seen a fast uptake in many industry segments. Mechanical properties superior to fusion welding, the ability to weld "unweldable" aluminium alloys and low distortion are often described as the main reasons for the fast industrial implementation of FSW. Most existing applications consist of long straight welding joints. READ MORE

2. Bacterial and fungal growth in soil: The effect of temperature and substrate addition
Abstract : Bacteria and fungi are the main agents in decomposition of soil organic matter. Their activity is determined by the availability and quality of substrate, especially its content of carbon, but also nitrogen and phosphorus. Other environmental factors, which affect the activity of the microbial community in soil, are temperature, moisture and pH. READ MORE

3. Low-temperature District Heating : Various Aspects of Fourth-generation Systems
Abstract : With decreasing heat demand and less availability of high-temperature heat supply in future energy systems, the current district heating systems may experience increased competition on the heat market. A viable option to mitigate increasing competition is to operate systems with lower temperature levels, and the most conceivable way to achieve lower temperature levels is to decrease return temperatures.

5. Temperature and heat losses simulation in core and winding of a power transformer
Abstract : Simulering av temperatur och värmeförluster i kärna och lindning för en högspänningstransformator “... Ett ljus som lyser dubbelt så starkt, varar hälften så länge …”, i analogi med ljuset så kan transformatorer köras med överlast inom vissa gränser, men med följden att livslängden blir kortare.
