1. 21. Evaluation of Asphalt Field Cores with Simple Performance Tester and X-ray Computed Tomography

   Författare :Florentina Angela Farcas; Björn Birgisson; Xiaohu Lu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asphalt mixture; dynamic modulus; flow number; simple performance tester; X-ray computed tomography; air voids distribution;

   Sammanfattning : The importance of aggregate structure and air voids distribution for asphalt mixture rutting and cracking performance has been well established on the basis of experience and is well documented in the literature. Past and current investigations are limited to assessment of performance based on macroscopic behavior due to the difficulty associated with the quantitative measurement and analysis of the internal structure of asphalt mixtures.

3. 22. On determining lost core viability in high-pressure die casting using Computational Continuum Mechanics

   Författare :Sebastian Kohlstädt; Pär Jönsson; Julio Hernandez; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-pressure die casting; lost salt cores; computational continuum mechanics; two-phase compressible flow; OpenFOAM; CFD; fluid-structure interaction; volume-of-fluid method;

   Sammanfattning : The subject of this thesis work is to investigate whether Computational ContinuumMechanics (CCM) can serve as a valuable tool for the casting engineerto determine a priori whether a housing concept with inlying geometries thatso far only exists in Computer Aided Design (CAD) will have the desired coolingperformance and will be manufacturable with an acceptable number ofrejects.As of spring 2019, no application in serial production of lost cores, i.

4. 23. Structural and functional analyses of infectious pancreatic necrosis virus (IPNV)

   Författare :Anna Hjalmarsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cellular localisation; glycosylation; VP3-RNA cores; virus-specified components; immuno dot blot; TCID50; IPNV; purification; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : Infectious pancreatic necrosis virus (IPNV) is a naked virus of an uncomplicated structure. In the interior part of the virion, the two segments of double-stranded RNA are located together with the minor structural protein VP1. This protein is detected in its free form as well as linked to the genome. LÄS MER
