  1. 1. Imaging of nucleocytoplasmic transcription factor dynamics in yeast

    Författare :Kristofer Bodvard; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transcription factor; single-cell; yeast; image analysis; Saccharomyces cerevisiae; light stress; Fluorescence microscopy; signalling;

    Sammanfattning : Fluorescence microscopy has proven to be an invaluable tool in identifying and understanding cell signalling, intracellular spatial and temporal dynamics, and cell-to-cell variability. This thesis focuses on imaging of nucleocytoplasmic transcription factor dynamics at the single cell level in yeast. LÄS MER

  3. 2. Strain-assisted corrosion cracking and growth rate inhibitors

    Författare :Andrey P Jivkov; Mekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; materialteknik; Mechanical engineering; Material technology; Materiallära; Stress intensity factor; Inhomogeneous materials; Crack evolution; Stress corrosion cracking; Moving boundary; hydraulics;

    Sammanfattning : A model for evolution of cracks as a result of strain-assisted corrosion is presented. The considered cracks possess a realistic geometry, where the tip region is an integral part of the crack surface instead of being a singular point. This geometry is either implicitly defined or is a consequence of crack nucleation from surface irregularities. LÄS MER

  5. 4. The Temporomandibular Joint in Juvenile Idiopathic Arthritis : Psychosocial, clinical, imaging and parotid saliva biomarkers

    Författare :Alexandra Dimitrijevic Carlsson; Per Alstergren; Kerstin Wahlund; Carin Starkhammar Johansson; Martina. Frodlund; Bijar Ghafouri; Robin Kahn; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomarkers; Juvenile Idiopathic Arthritis; Magnetic resonance imaging; Orofacial pain; Parotid gland; Plasma; Psychological distress; Psychosocial; Saliva; Stress; Temporomandibular joint; Biomarkörer; Juvenil idiopatisk artrit; Käkled; Magnetisk resonanstomografi; Orofacial smärta; Saliv; Spottkörtel; Stress;

    Sammanfattning : Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children. The disease can affect the temporomandibular joint (TMJ) and cause orofacial growth disturbances, pain, and jaw dysfunction. TMJ arthritis is often asymptomatic and therefore a challenging joint to diagnose. LÄS MER

  7. 5. Shear Fracture and Delamination in Packaging Materials : A study of Experimental Methods and Simulation Techniques

    Författare :Md. Shafiqul Islam; Sharon Kao-Walter; Christian Johansson; Johan Tryding; Blekinge Institute of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Package opening; Shear test specimen; Stress intensity factor; Finite Element simulation; Scanning electron microscopy; Polymers; Interlaminar shear delamination;

    Sammanfattning : Packages are the means of preservation, distribution and convenience of use for food, medicine and other consumer products. Package opening is becoming complicated in many cases because of cutting cost in design and production of opening techniques. LÄS MER
