  1. 1. Adipose tissue inflammation and coagulation in humans

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Medicine

    Författare :Mattias Ekström; Karolinska Institutet.; Karolinska Institutet.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background Adipose tissue (AT) is not only a store of energy but an endocrine organ with capacity to produce and release proinflammatory mediators into the circulation. Obesity is an inflammatory disease, with increased circulating levels of interleukin (IL)-6, due to synthesis in AT. LÄS MER

  2. 2. Satellite measurements of upper tropospheric water

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Medicine

    Författare :Mattias Ekström; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; cloud ice; upper troposphere; microwave; retrieval; the Odin satellite; humidity; limb-sounding;

    Sammanfattning : Water vapour and clouds in the upper troposphere have strong influence on the Earth's climate system. The present uncertainties regarding the distribution and feedback mechanisms of water to a changing climate are today among the greatest limitations for accurate climate predictions. LÄS MER

  3. 3. SiC CMOS and memory devices for high-temperature integrated circuits

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bismuth titanate Bi4Ti3O12 ; CMOS; ferroelectric capacitor; field oxide; inverter; metallisation; metal oxide semiconductor field effect transistor MOSFET ; ohmic contacts; ring oscillator; semiconductor processing; silicon carbide 4H-SiC ; CMOS; ferroelektrisk kondensator; fältoxid; halvledartillverkning; inverterare; kiselkarbid 4H-SiC ; metallisering; MOSFET; ohmska kontakter; ringoscillator; vismuttitanat Bi4Ti3O12 ; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : High-temperature electronics find use in extreme environments, like data logging in downhole drilling for geothermal energy production, inside of high-temperature turbines, industrial gas sensors and space electronics. The simplest systems use a sensor and a transmitter, but more advance electronic systems would additionally require a microcontroller with memory. LÄS MER

  4. 4. Sub-Millimetre Measurements of Upper Tropospheric Humidity

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Mattias Ekström; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Humidity and clouds in the upper troposphere are important factors for the Earth's radiative balance.Consequently a weakness in global climate models is that very little is known about the concentration of water vapour or the distribution and properties of clouds in this altitude region.
