  1. 21. Novel Processing and Electrical Characterization of Nanowires

    Författare :Kristian Storm; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gate; Capacitance; Hall effect; InP; InAs; Characterization; Nanowires; Processing; LED; Transistor; Fysicumarkivet A:2013:Storm;

    Sammanfattning : This thesis investigates novel electrical nanowire characterization tools and devices. Conventional characterization methods, long available to bulk semiconductor samples, have been adapted and transferred to the nanowire geometry. LÄS MER

  3. 22. The economics of sickness absence : social interactions, local cultures and working conditions

    Författare :Kristin Ekblad; Mikael Svensson; Lars Hultkrantz; Mats Persson; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Peer effect; absence; sickness absence; social norms; gender; age; municipality; domestic migration; working conditions; Economics; Nationalekonomi;

    Sammanfattning : The focus of this thesis is the study of social and psychosocial aspects of sickness absence. In Essay 1, Sickness Absence and Peer Effects – Evidence from a Swedish Municipality, detailed employment records from a Swedish public employer are used to investigate whether sick leave among work group colleagues influences individual sick leave.

  4. 23. Near wall fibre orientation in flowing suspensions

    Författare :Allan Carlsson; Daniel Söderberg; Fredrik Lundell; Helge I. Andersson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid mechanics; fibre orientation; shear flow; wall effect; fibre suspension; papermaking; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : This thesis deals with fibre orientation in wall-bounded shear flows. The primary application in mind is papermaking. The study is mainly experimental,but is complemented with theoretical considerations.The main part of the thesis concerns the orientation of slowly settlingfibres in a wall-bounded viscous shear flow.

  5. 24. Drowning-out crystallisation of benzoic acid : Influence of processing conditions and solvent composition on crystal size and shape

    Författare :Xiomara Holmbäck; KTH; []
    Nyckelord :solvent effect; drowning-out; crystallization; benzoic acid; solubility; crystal habit; crystal growth; interfacial energy; growth mechanism;

    Sammanfattning : The aim of the present investigation is to increase theunderstanding of the role played by the solvent in inhibitingor enhancing crystal growth. Drowning-out crystallizationexperiments has been performed by the controlled addition ofwater or ethanol water mixtures to a saturated solution ofbenzoic acid in ethanol-water mixtures. LÄS MER

  7. 25. Tendon transfer mechanics and donor muscle properties : implications in surgical correction of upper limb muscle imbalance

    Författare :Eva Pontén; Bertil Romanus; Umeå universitet; []
    Nyckelord :laser diffraction; sarcomere length; tendon transfer; spasticity; muscle morphology; myosin heavy chain; capillary; rabbit; human; cerebral palsy; stroke; handkirurgi; hand surgery;

    Sammanfattning : Tendon transfer surgery is used to improve the hand function of patients with nerve injuries, spinal cord lesions, cerebral palsy (CP), stroke, or muscle injuries. The tendon of a muscle, usually with function opposite that of the lost muscle function, is transferred to the tendon of the deficient muscle. LÄS MER
