2. 1. Particle Deposition Studies in a Laminar Wall Jet - The Hydrodynamic Influence on the Kinetics of Colloidal Deposition

   Author : Anders Göransson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shielding function; surface blocking; total internal reflection microscopy; laminar wall jet; random sequential adsorption; colloidal deposition; Food and drink technology; Livsmedelsteknik;

   Abstract : In the research area of cleaning and process hygiene it is important to understand the underlying mechanisms behind the deposition of particles and macromolecules onto surfaces. The deposition process is described as the transport of particles to the surface followed by attachment. READ MORE

4. 2. Experimental Study and Modelling of Spacer Grid Influence on Flow in Nuclear Fuel Assemblies

   Author : Diana Caraghiaur Garrido; Henryk Anglart; Dominique Bestion; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; spacer grid influence; annular flow; deposition; Lagrangian Particle Tracking;

   Abstract : The work is focused on experimental study and modelling of spacer grid influence on single- and two-phase flow. In the experimental study a mock-up of a realistic fuel bundle with five spacer grids of thin plate spring construction was investigated. A special pressure measuring technique was used to measure pressure distribution inside the spacer. READ MORE

5. 3. Atmospheric transport of persistent organic pollutants to aquatic ecosystems

   Author : Cecilia Agrell; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Temperature; Latitude; Deposition; PCB; Baltic Sea; Ekologi;

   Abstract : The load of persistent organic pollutants (POPs) is considered high in the Baltic ecosystem. The Baltic Sea spans over 12 latitudes and the regional differences in climate affect the behavior of POPs. READ MORE

6. 4. Quantitative microscopy of coating uniformity

   Author : Christina Dahlström; Tetsu Uesaka; Magnus Norgren; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coating uniformity; coating microstructure uniformity; base sheet effects; argon ion beam milling; scanning electron microscopy; image analysis; binder distributions; autocorrelation analysis; random deposition process; simulation;

   Abstract : Print quality demands for coated papers are steadily growing, and achieving coating uniformity is crucial for high image sharpness, colour fidelity, and print uniformity. Coating uniformity may be divided into two scales: coating thickness uniformity and coating microstructure uniformity, the latter of which includes pigment, pore and binder distributions within the coating layer.
