  1. 1. Optimization of time domain induced polarization data acquisition and spectral information content

    Författare :P.-I. Olsson; [2016-02-16]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; induced polarization 1P ; DCIP; spectral information; Data quality; Signal Processing;

    Sammanfattning : The need for detailed subsurface information is increasing due to city expansion and infill projects as well as subsurface construction projects. One common method for acquiring this geo-information is the direct current resistivity and time domain induced polarization method (DCIP) that measures the electrical resistivity and chargeability of the subsurface.

    Sammanfattning : By 2020 there will be 50 billion connected devices over the Internet. With the fast-increasing data traffic demand in both fixed and mobile networks, network operators need to migrate networks towards next generation solutions. LÄS MER

  3. 3. Modelling of Dislocation Bias in FCC Materials

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

    Författare :Zhongwen Chang; Pär Olsson; Christophe Domain; [2013]

    Sammanfattning : Irradiation induced void swelling is problematic for the application of austenitic steels under high dose irradiation. In this thesis, the swelling is characterized by dislocation bias. The dislocation bias is obtained using the finite element method, accounting for fcc copper and nickel under electron irradiation.

  4. 4. Antibiotic Resistance and the Cellular Currency S-adenosyl-methionine Modification of aminoglycosides and nucleic acids

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Sandesh Kanchugal P; Maria Selmer; Ditlev Brodersen; [2020]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antibiotic resistance; streptomycin; spectinomycin; X-ray crystallography; methyltransferase; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi;

    Sammanfattning : Streptomycin and spectinomycin are antibiotics that bind to ribosomes and inhibit protein synthesis. Common resistance mechanisms involve enzymatic modification of the two drugs by aminoglycoside nucleotidyltransferases (ANTs). The first part of this thesis covers the structural mechanism of two ANT enzymes. LÄS MER

  5. 5. WNT/FZD signaling : an odyssey from molecular pharmacology to brain (patho)physiology

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Physiology and Pharmacology

    Författare :Jacomijn P. Dijksterhuis; Karolinska Institutet.; Karolinska Institutet.; [2015]

    Sammanfattning : The 19 members of the lipoglycoprotein family of WNTs interact with the highly conserved cysteine-rich domain (CRD) of ten members of the Frizzled (FZD1-10) family. The seven transmembrane-spanning surface receptors are listed as G protein-coupled receptors and are known to interact with heterotrimeric G proteins as well as the scaffolding protein disheveled.
