  1. 1. Modeling Genome Evolution : Creation, Change and Destruction

    Författare :Mats Pettersson; Otto Berg; Paul Sniegowski; Uppsala universitet; []
    Nyckelord :Molecular biology; Theotretical biology; Population genetics; Stochastic modeling; Genome evolution; Molekylärbiologi;

    Sammanfattning : Historically, evolution has been studied either by looking at morphological traits in living organisms and the fossil record, or by using bioinformatics and comparative genomics. While highly useful for deducing evolutionary history, these approaches are not particularly well suited for studying the mechanisms of evolution. LÄS MER

  3. 3. Contribution to Wideband SAR Space-Time Processing, and Radar Remote Sensing of Sea Ice

    Författare :Mats I. Pettersson; Chalmers University of Technology; []
    Nyckelord :SAR; clutter suppression; space time adaptive processing; backprojection; remote sensing; moving target detection; radar scattering; Antenna array; wide band; sea ice;

    Sammanfattning : Synthetic Aperture Radar (SAR) has the capability to map the Earth with high resolution and is used in both civilian and military applications. The development of SAR systems is going towards higher resolution. Today there are Wide Band (WB) SAR instruments that have a resolution actually smaller than the operating wavelength. LÄS MER

  5. 5. Routine procedures in the care of the full-term newborn

    Författare :Miriam Pettersson; Mats H. Eriksson; Andreas Ohlin; Fredrik Ahlsson; Örebro universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Newborn; pain; neonatal hyperbilirubinemia; home phototherapy; neonatal hip examination; oral sweet solution; pain assessment;

    Sammanfattning : This thesis presents four studies on routine procedures used in the care of the full-term newborn. The overall aim of the thesis was to study the effects of these routines and endeavour to find ways to improve them.Study I, an observational study, included 28 healthy newborns, assessing pain during neonatal hip examination.
