  1. 6. Chondrocyte and extracellular matrix alterations in equine cartilage during development and inflammation

    Författare :Maria Löfgren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Osteoarthritis (OA) is a disease involving inflammation and subsequent degeneration of joint tissues. The disease progresses with time-dependent stages of degeneration, loss and remodelling of the extracellular matrix (ECM) of articular cartilage, and phenotypical changes in the chondrocytes.

  3. 7. Transient electromagnetic pulse propagation in temporally dispersive materials

    Författare :Igor Egorov; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Green functions; direct scattering; time domain; wave propagation; bi-gyrotropic; chiral; bi-isotropic; Forerunner; precursor; Green dyadics; Electronics and Electrical technology; Elektronik och elektroteknik;

    Sammanfattning : This thesis treats the problem of transient electromagnetic pulse propagation in temporally dispersive media. The analysis is performed using time-domain techniques. In particular, the dispersive wave splitting which decouples the Maxwell equations both in vacuum and inside the medium is utilized. LÄS MER

  4. 8. High Order Symmetric Finite Difference Schemes for the Acoustic Wave Equation

    Författare :Abraham Zemui; Bertil Gustafsson; Leif Abrahamsson; Per Weinerfelt; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; finite element method; mass lumping; high order; finite difference method; wave equation; Numerical Analysis; Numerisk analys;

    Sammanfattning : When someone speaks, or when a piano is played, sound waves are spread through the room. Physically the propagation of sound is governed by the acoustic wave equation. This thesis deals with the problem of finding solutions to this equation by numerical methods. LÄS MER

  5. 9. Modeling and Characterization of nonlinear Materials for Protection of Optical Sensors

    Författare :Anders Eriksson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis concerns nonlinear materials and experimental techniques for optical power limiting applications. Theoretical models to analyze and simulate related measurements were studied. Two different numerical modeling tools for propagation of optical radiation through optically nonlinear media were developed. LÄS MER

  7. 10. Effect of cycline-dependent kinase and matrix metalloproteinase inhibitors on hematopoietic and leukemic cells

    Författare :Hairong Song; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Rapid advances in molecular and cellular biology have improved the understanding of the mechanisms involved in leukemia development. Cyclin-dependent kinases (CDKs) and matrix metalloproteinases (MMPs) have been suggested as potential therapeutic targets and a number of pharmacologic inhibitors of CDKs and MMPs have been developed.
