  1. 41. Biomechanical Analysis of Stress and Stiffness of New Load-Bearing Implants

    Författare :Jinxing Huo; E. Kristofer Gamstedt; Benedikt Helgason; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering science with specialization in Applied Mechanics; Teknisk fysik med inriktning mot tillämpad mekanik;

    Sammanfattning : Medical implants are essential products for saving lives and improving life quality. Nowadays, the demand for implants, especially biocompatible and personalized ones, is increasing rapidly to deal with factors like congenital malformations, aging, and increasing prevalence of cancer.

  3. 42. Humidification in Evaporative Power Cycles

    Författare :Farnosh Dalili; KTH; []
    Nyckelord :Gas Turbines; EvGT; HAT; Humidification; Evaporator; Saturator;

    Sammanfattning : Evaporative gas turbine cycles (EvGT) show an exceptionalexhaust heat recovery potential, which makes them a strongcompetitor to other advanced gas turbine cycles, especiallyfrom small to intermediate sizes. Evaporative gas turbines aredistinguished by humidifying the working fluid beforecombustion at temperatures below the boiling point of water;and the heat required for evaporation of water is partly takenout of the exhaust gas.

  4. 43. Experimental acute ischemic renal failure and anticoagulation

    Författare :Henrik Druid; Olof Hellberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : This thesis is based on experimental studies on acute renal failure (ARF) in rats. The model employed is that of renal artery clamping, which causes a standardized, ischemic trauma to the kidney. LÄS MER

  5. 44. Modelling of forming and quenching of ultra high strength steel components for vehicle structures

    Författare :Magnus Eriksson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The doctoral thesis deals with modelling and simulations in integrated product and process development. The research concerns with development of models and methods for simulation of component manufacturing and product functionality. LÄS MER

  7. 45. Resistance of Friction Connections with Open Slotted Holes in Towers for Wind Turbines

    Författare :Christine Heistermann; Peter Schaumann; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : The most common solutions for in-situ connections of steel tubular towersegments of onshore wind turbines are ring flange connections. These havecertain drawbacks, such as e.g. costly production, long delivery time and ratherlow fatigue endurance. LÄS MER
