  2. 1. Foam-formed Fiber Networks: Manufacturing, Characterization, and Numerical Modeling : With a Note on the Orientation Behavior of Rod-like Particles in Newtonian Fluids

    Author : Majid Alimadadi; Per Gradin; Pär Jonsén; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D fiber network structure; foam forming; numerical modeling; compression simulation; orientation; wall-bounded flow; CFD; Jeffery orbits; LS-DYNA;

    Abstract : Fiber networks are ubiquitous and are seen in both industrial materials (paper and nonwovens) and biological materials (plant cells and animal tissues). Nature intricately manipulates these network structures by varying their density, aggregation, and fiber orientation to create a variety of functionalities. READ MORE

  4. 2. Dynorphin A – Interactions with receptors and the membrane bilayer

    Author : Johannes Björnerås; Lena Mäler; Astrid Gräslund; Göran Widmalm; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biophysics; biofysik; Biochemistry; biokemi;

    Abstract : The work presented in this thesis concerns the dynorphin neuropeptides, and dynorphin A (DynA) in particular. DynA belongs to the wider class of typical opioid peptides that, together with the opioid receptors, a four-membered family of GPCR membrane proteins, form the opioid system. READ MORE

  5. 3. The opioid peptide dynorphin A : Biophysical studies of peptide–receptor and peptide–membrane interactions

    Author : Johannes Björnerås; Lena Mäler; Astrid Gräslund; Scott Prosser; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dynorphin A; opioid receptor; neuropeptide; bicelles; NMR; diffusion; decomposition; Biophysics; biofysik;

    Abstract : The work presented in this thesis concerns the opioid peptide dynorphin A (DynA). DynA functions primarily as a neurotransmitter and belongs to the family of typical opioid peptides. These peptides are a part of the opioid system, together with the opioid receptors, a family of GPCR membrane proteins. READ MORE

  6. 4. A Co-Simulation Tool Applied to Hydraulic Percussion Units

    Author : Håkan Andersson; Daniel Leidermark; Kjell Simonsson; Joakim Holmberg; Pär Jonsén; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this dissertation, a co-simulation tool is presented that is meant to comprise a more comprehensive environment for modelling and simulation of hydraulic percussion units, which are used in hydraulic hammers and rock drills. These units generates the large impact forces, which are needed to demolish concrete structures in the construction industry or to fragment rock when drilling blast holes in mine drifting. READ MORE

  7. 5. Foam modeling including pore gas interaction for crashworthiness analysis

    Author : Mats L Landervik; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Foams; Hyperelasto-viscoplasticity; Non-linear dynamics.; Staggered solution; Theory of Porous Media; Constitutive modeling;

    Abstract : Foams are used in vehicles for three main functions: enhancing comfort, e.g.soft foams used in seats cushions, energy absorbtion, e.g. READ MORE
