2. 16. Dynamics of particles in fluids: effects of correlations and interactions

   Author : Anshuman Dubey; Göteborgs universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; particle-laden flows; turbulent aerosols; collisions; charged droplets; hydrodynamic interactions;

   Abstract : Particles suspended in turbulent fluid flows are common in Nature and in technological applications. In some cases, the relative dynamics of spherical particles may be of interest. One example is small rain droplets in turbulent clouds. The dynamics of nearby droplets is correlated because they experience a correlated airflow. READ MORE

4. 17. Multiparticle Production in Strong Interactions

   Author : Fredrik Söderberg; Centrum för miljö- och klimatvetenskap (CEC); []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hadronisation; QCD; Bose-Einstein correlations; Elementary particle physics; Elementarpartikelfysik; quantum field theory; String fragmentation; kvantfältteori; Fysicumarkivet A:2003:Söderberg;

   Abstract : An alternative formulation of the Lund fragmentation model for string states without gluons is presented. It is shown that the fragmentation process can be factorised into a product of transition operators with well-defined eigenfunctions and corresponding eigenvalues. READ MORE

5. 18. Modelling calving and sliding of Svalbard outlet glaciers : Spatio-temporal changes and interactions

   Author : Dorothée Vallot; Rickard Pettersson; Veijo Pohjola; Ken Mattsson; Tómas Jóhannesson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cryospheric science; glacier modelling; time-lapse imagery; undercutting; sliding inversion; discrete particle model; calving model; subglacial hydrology; sliding law; automatic detection method; calving events size and frequency; ocean interaction; melt water runoff; ice dynamics; ice flow model; Geovetenskap med inriktning mot naturgeografi; Earth Science with specialization in Physical Geography;

   Abstract : Future sea level rise associated to global warming is one of the greatest societal and environmental challenges of tomorrow. A large part of the contribution comes from glaciers and ice sheets discharging ice and meltwater into the ocean and the recent worldwide increase is worrying. READ MORE

6. 19. Surface Interactions in Powder Injection Moulding

   Author : Elisabeth Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surfactants; powder injection moulding PIM ; rheology; steel powder; surface interactions; XPS; SIMS; adsorption; surface composition;

   Abstract : Powder Injection Moulding (PIM) is an attractive technique for producing complex components in large quantities my means of powder technology. The process includes mixing powder with a suitable binder, usually a thermoplastic polymer. Because of the large attractive forces between small particles the powder can be agglomerated in the binder. READ MORE

7. 20. Micro-by-micro interactions : Aggregation dynamics, biofilms, and ecotoxicological impacts of suspended solids

   Author : Sophia Reichelt; Elena Gorokhova; Rehab El Shehawy; Julien Gigault; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; suspended solids; microplastics; bacteria; biofilm; aggregation; ecotoxicology; microalgae; Environmental Sciences; miljövetenskap;

   Abstract : Increasing concerns arise regarding the environmental risk of microplastics (MP) and their interactions with biota, prompting numerous effect studies. However, current ecotoxicology methods fall short when it comes to assessing MP impacts. READ MORE
