  2. 1. Wave-actuated Preform Infiltration Routines in MMC Production

    Author : Lars-Olov Pennander; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material technology; Magnetostrictive; Vibration; Actuation; Wave; Infiltration; Preform; Metal; Composites; MMC; Materiallära; materialteknik;

    Abstract : The implementation of highly magnetostrictive wave-actuator techniques in preform infiltration processes for metal-matrix composite production is described. Metal matrix materials require additional methods to handle the content, shape and position of the ceramic reinforcements, which are not required for metal alloy casting. READ MORE

  4. 2. Local infiltration analgesia in knee arthroplasty

    Author : Per Essving; Kjell Axelsson; Lars Weidenhielm; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Knee arthroplasty; minimally invasive surgery; ropivacaine; ketorolac; intrathecal morphine; local infiltration analgesia; Surgery; Kirurgi;

    Abstract : Local infiltration analgesia (LIA) is a new technique for postoperative pain management following knee arthroplasty. LIA involves a long-acting local anesthetic (ropivacaine), a non-steroid anti-inflammatory drug (ketorolac) and epinephrine infiltrated into the knee joint during surgery and injected postoperatively via a catheter.

    Abstract : Natural ventilation is the dominating ventilation process in ancient buildings like churches, and also in most domestic buildings in Sweden and in the rest of the world. These buildings are naturally ventilated via air infiltration and airing. READ MORE

  6. 4. Nitrogen transformations in wetlands: Effects of water flow patterns

    Author : Torbjörn Davidsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrobiology; hydrology; infiltration; subsurface flow; surface flow; wetland; nitrogen; Denitrification; mineralization; nitrification; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Abstract : In this thesis, I have studied nitrogen turnover processes in watermeadows. A watermeadow is a wetland where water infiltrates through the soil of a grassland field. READ MORE

  7. 5. Heat transfer phenomena and mould flux lubrication in continuous casting of steel

    Author : Akira Yamauchi; KTH; []
    Keywords : Heat Transfer; Thermal Conductivity; Contact Resistance; Mould Flux; Solidification; Lubrication; Infiltration; Friction; Shear Stress; Modeling; Crystallization; Rupture Strength; Solidus; High-Speed Casting; Viscosity; Elasticity; Uniform Cooling;

    Abstract : Overall thermal resistance of the mould flux was measured tomake clear the influence of the mould flux properties on theheat transfer behavior in continuous casting, especiallythermal conductivity and the formation of air gaps in thisstudy. From the investigation of the effect of the mouldsurface temperature and physical properties of the mould fluxon heat transfer through the flux film, following knowledge hasbeen obtained. READ MORE
