  1. 1. A study of possible chemical inhomogeneities of dwarf irregular galaxies and the influence on the Z-L relationship

    Författare :Ana Maria Hidalgo-Gámez; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; dwarf irregular galaxies; chemical abundances; metallicity-luminosity relationship; individual galaxies: NGC 6822; IC 4662; IC 10; ESO 245-G05; NGC 1569; IC 5152; DDO 53 and DDO 190; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik; astronomi; Astronomy;

    Sammanfattning : A study on the chemical abundances of dwarf irregular galaxies (dI's) is presented in this work. This type of galaxies have typically low metallicity. First of all, a definition of dI is proposed, in order to obtain a homogeneous group of targets. LÄS MER

  3. 2. Modelling, Analysis and Design of RF Mixed-Signal Mixer for Wireless Communications

    Författare :Li Li; KTH; []
    Nyckelord :RF; INTEGRATED CIRCUITS; MIXED-SIGNAL; MIXER; WIRELESS COMMUNICATIONS; NOISE ANALYSIS; SUBSTRATE COUPLING.;

    Sammanfattning : The explosive growth of the market for wirelesscommunications is driving low cost, highly integrated designsand complex RF/analog mixed-signal integrated circuit (RF AMSIC) products. RF transceiver application is one of the mostimportant wireless applications. LÄS MER

  4. 3. Bladder pain syndrome/interstitial cystitis. Studies on classic BPS/IC, ESSIC type 3C, with special reference to the role of nitric oxide

    Författare :Yr Logadottir; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bladder Pain Syndrome BPS ; Interstitial Cystitis IC ; Nitric Oxide NO ; Nitric Oxide Synthase NOS ; Inflammatory mediators; Interleukin-17; Mast cells;

    Sammanfattning : Patients presenting with symptoms of Bladder Pain Syndrome (BPS) are challenging to the urologist. Previously known as Interstitial Cystitis (IC), this syndrome has been extensively debated and investigated. IC mainly affects women, only 1 or 2 out of 10 patients are males. LÄS MER

  5. 4. Activation and inhibition of diiron and iron-manganese ribonucleotide reductases

    Författare :Ana Popović-Bijelić; Astrid Gräslund; Anders Hofer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; class Ic; C. trachomatis; cytotoxicity; KP772; lanthanum; manganese–iron cofactor; metal complex; oligopeptide inhibitor; ribonucleotide reductase; Triapine; tyrosyl radical; Biophysics; biofysik;

    Sammanfattning : Ribonucleotide reductase (RNR) catalyses the reduction of ribonucleotides to deoxyribonucleotides. In conventional class I RNRs the active site is located in the R1 subunit, and the R2 subunit contains a diiron cofactor and a stable tyrosyl radical essential for activity. LÄS MER

  7. 5. High-Resolution Studies of Silicide-films for Nano IC-Components

    Författare :Tobias Jarmar; Fredric Ericson; Ulf Smith; Terje Finstad; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; thin films; titaniumsilicide; nickel-germanosilicide; ternary phase diagram; textured germanosilicide; high resolution materials analysis; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The function of titanium- and nickel-silicides is to lower the series resistance and contact resistivity in gate, source and drain contacts of an integrated circuit transistor. With decreasing dimensions, the low resistivity C54 TiSi2 is not formed and stays in its high resistivity phase C49. LÄS MER
