  1. 6. Magnetic Resonance Imaging of Human Brown Adipose Tissue : Methodological Development and Application

    Författare :Elin Lundström; Joel Kullberg; Håkan Ahlström; Lars Johansson; Robin Strand; Sven Månsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brown adipose tissue; Magnetic resonance imaging; Positron emission tomography; Image segmentation; Glucose metabolism;

    Sammanfattning : Brown adipose tissue (BAT) is a thermogenic organ with the main human depot located in the cervical-supraclavicular (sBAT) region. BAT is proposed as a potential therapeutic target for obesity and diabetes. LÄS MER

  3. 7. On the analysis of cast structure and its changes during hot working of forging ingots

    Författare :Jan Sarnet; Hasse Fredriksson; Alec Mitchell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Forging ingots are hot worked to consolidate structural imperfections and refine the microstructure. Possible imperfections are segregations, porosities, cracks, and inclusions. In this thesis, techniques and methods for the characterisation of behaviour and properties of ingots and forgings. LÄS MER

  4. 8. Innovative Contact Free Sensors for Metallurgical Process Control

    Författare :Donald Malmberg; Stuart M. Millman; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; microwave spectroscopy; laser; TDLAS; high temperature; gas; slag; NATURAL SCIENCES; NATURVETENSKAP; spectroscopy; slag analysis; high temperatures; Mät- och instrumenteringsteknik; Instrumentation technology; TDLAS; microwave; laser; Fysicumarkivet A:2003:Malmberg;

    Sammanfattning : The steel- and metal industry has an extensive production processing comprising many different process steps of solid, gaseous and liquid nature. Thus it is obvious that a number of different measurement technologies must be used to collect and evaluate key physical parameters which are necessary to control the production processes. LÄS MER

  5. 9. On the Design of Residential Condensing Gas Boilers

    Författare :Mikael Näslund; Energihushållning; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; flue systems; modelling; efficiency; condensing boilers; space heating; natural gas; Energiforskning;

    Sammanfattning : Two main topics are dealt with in this thesis. Firstly, the performance of condensing boilers with finned tube heat exchangers and premix burners is evaluated. Secondly, ways of avoiding condensate formation in the flue system are evaluated. LÄS MER

  7. 10. Experimental study of single fuel jet combustion and high-cycle regenerative systems

    Författare :Simon Lille; KTH; []
    Nyckelord :combustion; preheated air; energy savings;

    Sammanfattning : High Temperature Air Combustion (HTAC) is a technique toreduce consumption of fuel and decrease NOxformation in furnaces. The main change that occursin the furnace chamber is that the flow pattern of flue gasesaltered resulting in a more uniform heat transfer andtemperature profile. LÄS MER
