1. 26. Bio-Nano Interactions : Synthesis, Functionalization and Characterization of Biomaterial Interfaces

   Författare :Yixiao Cai; Xia Wei; Mikael Karlsson; Martin Andersson; Uppsala universitet; []
   Nyckelord :Bioactive surfaces; nanocrystalline diamond; hydroxyapatite; protein secondary structure; protein absorption; auditory neurons; single crystalline rutile; nano morphology; surface functionalisation; in vitro biomineralisation; translucent nano-ceramics; bio-window material; material characterisation.; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

   Sammanfattning : Current strategies for designing biomaterials involve creating materials and interfaces that interact with biomolecules, cells and tissues.  This thesis aims to investigate several bioactive surfaces, such as nanocrystalline diamond (NCD), hydroxyapatite (HA) and single crystalline titanium dioxide, in terms of material synthesis, surface functionalization and characterization.

3. 27. Enabling Surface Cleaning Robot for Large Food Silo

   Författare :Kinan Dandan; Amy Loutfi; Lars Karlsson; Mikael Ekström; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Confined space; surface cleaning robot; motion control; static and dynamic analysis;

   Sammanfattning : Working conditions in the dry cleaning and sanitation of confined interior spaces are often extreme, and workers need overall protection with tight clothing, helmets, face mask, earmuffs, and respirators. The environment is dirty, noisy with bad visibility and heavy with a high static work load. LÄS MER

4. 28. Diamond Microfabrication for Applications in Optics and Chemical Sensing

5. 29. Contributions to quantitative dynamic contrast-enhanced MRI

   Författare :Anders Garpebring; Mikael Karlsson; Ronnie Wirestam; Nils Östlund; Jón Hauksson; Steven Sourbron; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic contrast-enhanced MRI; quantitative imaging; parameter estimation; uncertainty estimation; arterial input function; radiofysik; radiation physics;

   Sammanfattning : Background: Dynamic contrast-enhanced MRI (DCE-MRI) has the potential to produce images of physiological quantities such as blood flow, blood vessel volume fraction, and blood vessel permeability. Such information is highly valuable, e.g., in oncology. LÄS MER

7. 30. Systematic analysis of a radiological diagnostic system : A method for application in the effective use of x-rays in intraoral radiology

   Författare :Ebba Helmrot; Mikael Karlsson; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : The effective use of an imaging system in diagnostic radiology implies an optimisation process. This demands knowledge and relevant descriptions of the various components, the X -ray units, the objects and receptors. LÄS MER
