  2. 11. On improvement of cast iron brake discs for heavy vehicles

    Author : Gael le Gigan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brake disc; cast iron; hot spots; cracking; elevated temperatures; material modelling; finite element analysis; drag braking; material testing; rig experiment; fatigue assessment;

    Abstract : Disc brakes are commonly used in motorcycles, passenger cars, commercial vehicles, heavy-duty vehicles, passenger trains and landing gears of airplanes. Depending on the application, a wide variety of brake discs have been developed, with a multitude of designs, geometries and materials. READ MORE

  4. 12. Characteristics of cast magnesium alloys : microstructures, defects and mechanical properties

    Author : Haiping Cao; Anders Jarfors; Linköpings universitet; []
    Keywords : Mg alloys; microstructure; mechanical properties; defects; modelling; segregation bands; hot tear; mould constraint; semi-solid casting.; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Magnesium is the lightest of all structural metals. As such, and combined  with good mechanical and physical properties, it forms the basis for commercial alloys that have found successful use in a wide variety of applications. READ MORE

  5. 13. High-Temperature Corrosion-Fatigue of Cast Alloys for Exhaust Manifolds

    Author : Shengmei Xiang; Joakim Odqvist; Baohua Zhu; Johan Ahlström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High temperature; corrosion fatigue; low-cycle fatigue; cast alloys; high-temperature oxidation; intermetallic phase; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The introduction of gas-driven Otto engine and the corresponding usage of bio-fuels in heavy-duty engines will render the exhaust atmosphere more corrosive and bring a higher working temperature to exhaust manifolds. The current service material, a ferritic ductile cast iron called SiMo51, will soon meet its upper temperature limit set by the ferrite-austenite transformation at 860ºC. READ MORE

  6. 14. On the treatment of tibial shaft fractures

    Author : Abbas Karladani; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cast; Distraction; Dynamometry; Fracture; Limb lengthening; Nailing; Outcome; Psychometry; Shaft; Soft tissue; Tibial;

    Abstract : The aim of this thesis was to evaluate those factors, which have predictive value for development of complications after tibial shaft fractures, and to evaluate the outcome of the available treatment methods for closed, as well as open tibial shaft fractures associated with extensive soft-tissue injury. To determine the factors, which influence healing speed, we reviewed 100 consecutive patients with 104 tibial shaft fractures tibial shaft fractures. READ MORE

  7. 15. Integrating bioinformatics and physiology to describe genetic effects in complex polygenic diseases

    Author : Hemang Parikh; diabetes och endokrinologi Genomik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Insulin sensitivity; Type 2 diabetes mellitus; Skeletal muscle; Gene expressionprofiling; TXNIP; Maximal oxygen uptake; Type 1 fibers; NDUFB5; CPT1B; ATP5C1; AHNAK; CAST; Genome-wide association studies.;

    Abstract : Type 2 diabetes mellitus (T2DM) results from interaction between genetic and environmental factors. The worldwide prevalence of T2DM is increasing rapidly due to reduction in physical activity, increase in dietary intake, and the aging of the population. READ MORE
