1. Formation of solar bipolar regions : Magnetic flux concentrations from suction of the negative effective magnetic pressure instability
Abstract : Sunspots stand out on the visible solar surface. They appear as dark structures evolving and changing over time. They host energetic and violent events, like coronal mass ejections and flares, and concentrate strong magnetic fields. READ MORE

2. Study of a Large Deformable Mirror Concept
Abstract : It is attractive to integrate a large deformable mirror for adaptive optics into an astronomical telescope rather than using relay optics within an auxiliary instrument. However, the resulting large deformable mirror can be expensive, particularly for extremely large telescopes. READ MORE

3. On Film Cooling of Turbine Guide Vanes : From Experiments and CFD-Simulations to Correlation Development
Abstract : To achieve high thermal efficiency in modern gas turbines, the turbine-inlet temperature has to be increased. In response to such requisites and to prevent thermal failure of the components exposed to hot gas streams, the use of different cooling techniques, including film cooling, is essential. READ MORE

4. Wetting and drying of aerogel-based coating mortars in Swedish climates
Abstract : Aerogel-based coating mortars (ACMs) have emerged as energy-efficient wall finishes with thermal conductivities of 30–50 mW/(m∙K). These coating mortars represent a promising alternative to traditional thermal insulation materials for retrofitting uninsulated building envelopes particularly in culturally significant structures.

5. Transporting highly concentrated slurries with centrifugal pumps : the thickened minerals tailings example
Abstract : New technologies are continuously considered for the handling and deposition of tailings. With thickened tailings only a fraction of water used conventionally reaches the disposal area, thus limiting sizes of water holding dam facilities and areas to be rehabilitated. Heat may also be recovered with direct water circulation from the thickening. READ MORE
