2. 1. Spontaneous online tutoring : Students’ support of their own and other students’ process of inquiry in online text-based tutoring

   Author : Malin Jansson; Stefan Hrastinski; Stefan Stenbom; Fredrik Enoksson; Jennifer Richardson; KTH; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Teknik och lärande; Technology and Learning;

   Abstract : The use of online technologies has made education more accessible. In online education, there are increased expectations for students to be self-directed and take responsibility for their learning. Research has also shown that students can benefit from learning from each other. READ MORE

4. 2. Turbulence Modelling of Flows Related to Wall-Cooling Applications

   Author : Stefan Jansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; low-Reynolds number models; second-order-moment closures; turbulent heat transfer; two-equation models; film-cooling; near-wall models; turbulence modelling;

   Abstract : Engineering flows are generally characterised by complex strain field and turbulence structure arising from a combination of shear, curvature, separation and recirculation etc. Under such flow conditions, transport by turbulent velocity fluctuations can make a significant contribution to the transport of momentum, heat and mass.

   Author : Stefan Candefjord; Tomas Jansson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical Engineering for Healthcare; Medicinsk teknik för hälsovård;

   Abstract : Prostate cancer (PCa) is the most common male cancer in Europe and the US, and only lung and colorectal cancer have a higher mortality among European men. In Sweden, PCa is the most common cause of cancer-related death for men. READ MORE

6. 4. Microstructure and Mechanical Properties of Magnetron Sputtered Refractory Metal Thin Films

   Author : Stefan Fritze; Ulf Jansson; Erik Lewin; Petr Vasina; Uppsala universitet; []
   Keywords : thin films magnetron sputtering; refractory metals; high entropy alloys; mechanical properties; transition metal carbides; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Abstract : The design and development of new multifunctional materials that exhibit a combination of high hardness and ductility, as well as a high corrosion resistance and thermal stability, is one of the key challenges in the field of material science. The focus of this thesis is on the development of novel multifunctional magnetron sputtered CrNbTaTiW–C based thin films. READ MORE
