2. 1. The flow of pulp suspensions

   Author : Helena Fock; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pulp suspensions; Velocity profile; Concentration profile; Wall layer; Particle image velocimetry; Flow behaviour; Computational fluid dynamics; Ultrasound velocity profiling;

   Abstract : Large quantities of pulp suspensions are handled in the pulp and paper industry and knowledge of their flow behaviour is very important in the design and operation of process equipment. Despite this, there is still a lack of a fundamental understanding of the mechanisms of the pulp suspension flow. READ MORE

5. 3. Methods for the Evaluation of Wingsails with a Crescent-Shaped Profile

   Author : Heng Zhu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind-assisted ship propulsion; rigid wingsail; light weight structure; crescent-shaped profile; wind-assisted ship propulsion.;

   Abstract : Seaborne transportation accounts for a large proportion of greenhouse gas (GHG) emissions. The International Maritime Organization (IMO) has stipulated that GHG emissions should be reduced by 50% before 2050 compared to 2018. The use of wind-assisted ship propulsion (WASP) is considered one of the most effective ways to reduce GHG emissions. READ MORE

6. 4. Development of Multi-grit cBN Grinding Wheel for Crankshaft Grinding

   Author : Nastja Macerol; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crankshaft; grinding; wear; grit concentration; grit toughness; grinding wheels; grit size; automotive; grit shape; cubic Boron Nitride;

   Abstract : A crankpin, part of a crankshaft, has a complex profile that is difficult to grind. The process often causes challenges such as excessive heat on the crankpin sidewall and wheel wear on the radius, causing reduced dressing interval. Different solutions were proposed to overcome these challenges, mainly focusing on the process, i.e. READ MORE

7. 5. Miniaturised Microwell-based Cell Assays

   Author : Emilie Weibull; Helene Andersson Svahn; Albert van den Berg; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microwell; miniaturisation; high-resolution imaging; high-throughput; cell culture; single-cell; clone; heterogeneity; antibiotic susceptibility testing; concentration gradient; interfacing; microchannels; cell retrieval;

   Abstract : Cell heterogeneity in genetically identical cell populations is becoming a well-known and important phenomenon in cell biology. Current methods commonly utilise population-based analysis founded on averaged result. Hence there is a need for high-throughput cell assays on the single-cell level. READ MORE
