  1. 1. Adipose tissue inflammation and coagulation in humans

    Författare :Mattias Ekström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    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

  3. 2. Satellite measurements of upper tropospheric water

    Författare :Mattias Ekström; Chalmers tekniska högskola; []
    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

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

    Författare :Mattias Ekström; Carl-Mikael Zetterling; B. Gunnar Malm; Tobias Erlbacher; KTH; []
    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

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

    Författare :Mattias Ekström; Chalmers tekniska högskola; []
    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.

  7. 5. On the use of traffic flows for improved transportation systems : Mathematical modeling and applications

    Författare :Henrik Fredriksson; Mattias Dahl; Johan Holmgren; Benny Lövström; Joakim Ekström; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mathematical modeling; Transportation systems; Link flows; Mathematics and applications; Matematik med tillämpningar;

    Sammanfattning : This thesis concerns the mathematical modeling of transportation systems for improved decision support and analysis of transportation-related problems. The main purpose of this thesis is to develop and evaluate models and methods that exploit link flows. LÄS MER
