  1. 1. Applications of hydrodynamic forces for membrane chromatography

    Författare :Björn Johansson Fast; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane chromatography; FRAP; Protein accumulation; Supported lipid bilayer; Microfluidics; SEEC; Diffusion; Hydrodynamic forces; Label-free;

    Sammanfattning : Membrane proteins are proteins that reside in the cell membrane. Due to their position in the cell membrane, the barrier between the cell interior and exterior, they are vital to cell signaling. Moreover, the presence of membrane proteins in the cell's signaling pathways make membrane proteins important drug targets. LÄS MER

  3. 2. Hydrodynamic flow for deterministic sorting of cell-membrane components

    Författare :Björn Johansson Fast; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gold nanoparticles; Diffusion; Microfluidics; Native membrane vesicles; Single particle tracking; Protein enrichment; Hydrodynamic forces; Supported lipid bilayer; Size determination;

    Sammanfattning : The biological membrane, an amphiphilic structure that is the barrier between the cell interior and exterior, is one of the vital building blocks of all cells. Not only does it define the outer boundaries of the cell, it also carries important biological function by virtue of the proteins and other molecules that constitute the membrane, the function of which is in turn intimately coupled to their association with the lipid-based membrane.

  4. 3. A Study of Some Temporal Properties of the Human Visual Evoked Potential, and Their Relation to Binocular Function

    Författare :Björn Johansson; Peter Jakobsson; Anders Sjöström; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; VEP Visual Evoked Potential ; contrast sensitivity; binocularity; latency; Fourier analysis; strabismus; amblyopia; Ophtalmology; Oftalmologi;

    Sammanfattning : As disturbed binocular functions in small children may lead to severe amblyopia it is of interest to detect it as early as possible. Most tests for binocular functions, however, demand active cooperation and may be unreliable in children up to 4-5 years of age. LÄS MER

  5. 4. Feedforward Control in Dynamic Situations

    Författare :Björn Johansson; Erik Hollnagel; Berndt Brehmer; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human; computer interaction; informatioon policy; organisational control; Computer science; Datavetenskap;

    Sammanfattning : This thesis proposal discusses control of dynamic systems and its relation to time. Although much research has been done concerning control of dynamic systems and decision making, little research exists about the relationship between time and control. Control is defined as the ability to keep a target system/process in a desired state. LÄS MER

  7. 5. Evaluating Fast and Efficient Modeling Methods for Simulation-Based Optimization

    Författare :Simon Lidberg; Amos H. C. Ng; Tehseen Aslam; Marcus Frantzén; Björn Johansson; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Sammanfattning : As the industry in general, and the automotive industry in particular, is transforming -- due to new technologies and changes in market demands through electrification, digitalization, and globalization -- maintaining a competitive edge will require better predictions. Better predictions of production performance allows companies to capitalize on opportunities, avoid costly mistakes, and be proactive about change. LÄS MER
