  2. 1. Water, hyaluronan and surface shape in corneal wound healing after excimer surgery : experimental studies

    Author : Beat A Weber; Karolinska Institutet; Karolinska Institutet; []
    Keywords : photorefractive keratectomy; excimer laser; rabbit; cornea; wound healing; microradiography; hyaluronan; planimetry; leukocyte protein marker; haze; regression; surface irregularities; subepithelial deposits; remodeling; epithelial hyperplasia; corticosteroids;

    Abstract : Excimer laser photorefractive keratectomy (PRK) has evolved to a widely performed procedure. The excimer laser corrects refractive ametropias by removing a calculated amount of anterior corneal stroma with great precision and with minimal damage to the adjacent tissues. The correction of myopia up to -5. READ MORE

  4. 2. Extending the Reach of Computational Approaches to Model Enzyme Catalysis

    Author : Beat Anton Amrein; Shina Caroline Lynn Kamerlin; Adrian Mulholland; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; epoxide hydrolase; enantioselectivity; regioselectivity; enantioconvergence; biocatalysis; empirical valence bond; computational directed evolution;

    Abstract : Recent years have seen tremendous developments in methods for computational modeling of (bio-) molecular systems. Ever larger reactive systems are being studied with high accuracy approaches, and high-level QM/MM calculations are being routinely performed. READ MORE

  5. 3. Dipolar recoupling in magic-angle-spinning nuclear magnetic resonance

    Author : Andreas Brinkmann; Beat Meier; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical Chemistry; fysikalisk kemi;

    Abstract : This thesis concerns the development of radio-frequency pulse sequences in magic-angle-spinning solid-state nuclear magnetic resonance.First, two classes of pulse sequences are presented which are synchronized with the sample rotation. READ MORE

  6. 4. On the beat : human movement and timing in the production and perception of music

    Author : Sofia Dahl; Anders Askenfelt; David Huron; KTH; []
    Keywords : HUMANIORA; HUMANITIES; Music; Musikvetenskap;

    Abstract : This thesis addresses three aspects of movement, performance and perception in music performance. First, the playing of an accent, a simple but much used and practiced element in drumming is studied, second, the perception of gradually changing tempo, and third, the perception and communication of specific emotional intentions through movements during music performance.

  7. 5. Beat-to-beat variability of QRS amplitude and heart rate in ischemic heart disease : diagnostic potentials

    Author : Inger Hagerman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : autonomic blockade; beat-to-beat variability; chaos; coronary arterydisease; correlation dimension; dobutamine; ECG; electrical heterogeneity; fractal dimension; heart rate variability; Lyapunov exponent; nonlinear; QRSvariance; surrogate data;

    Abstract : The diagnostic potential of beat-to-beat QRS amplitude variability in patients with coronary artery disease (CAD) was evaluated with variance ECG and compared to exercise stress test and myocardial scintigraphy (SPECT). Two high prevalence populations of 199 and 166 patients each were investigated. READ MORE
