    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dioxin; dioxin-like compounds; isomer distribution pattern; homologue profile; injection; O2PLS; PCDD; PCDF; PCN; PCBz; PCPh; MSW combustion; formation; chlorination; flue gas; quench profiles; Environmental chemistry; Miljökemi;

    Sammanfattning : This thesis contributes to an increased understanding of the formation of dioxins and dioxin-like compounds in combustion processes. Although emissions to air from waste incineration facilities have been greatly reduced by the use of efficient air pollution control measures, the resulting residues (ashes and filters) are highly toxic and are classified as hazardous waste.

  2. 2. Housing policy and family formation

    Författare :Cecilia Enström Öst; Thomas Lindh; Henry Ohlsson; Mats Wilhelmsson; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; housing economics; housing policy; family formation; housing tenure; homeownership; Economics; Nationalekonomi; Economics; Nationalekonomi;

    Sammanfattning : Essay 1: This paper addresses the impact on housing consumption of a decrease in housing allowance among single recipient parents living in rental apartments. We take advantage of an imposed limit on the recipients’ dwelling size in the Swedish housing allowance reform in 1996-1997 that can be argued to be close to a natural experiment. LÄS MER

  3. 3. Crossing the Midline : Locomotor Neuronal Circuitry Formation

    Författare :Fatima Memic; Klas Kullander; Avihu Klar; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CPG; CIN; neuronal network; locomotion; left-right alternation;

    Sammanfattning : Networks at various levels of the nervous system coordinate different motor patterns such as respiration, eye or hand movements and locomotion. Intrinsic rhythm-generating networks that are located in the spinal cord generate motor behaviors that underlie locomotion in vertebrates. LÄS MER

  4. 4. Automated Tissue Image Analysis Using Pattern Recognition

    Författare :Jimmy Azar; Anders Hast; Ewert Bengtsson; Martin Simonsson; Marco Loog; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tissue image analysis; pattern recognition; digital histopathology; immunohistochemistry; paired antibodies; histological stain evaluation; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Automated tissue image analysis aims to develop algorithms for a variety of histological applications. This has important implications in the diagnostic grading of cancer such as in breast and prostate tissue, as well as in the quantification of prognostic and predictive biomarkers that may help assess the risk of recurrence and the responsiveness of tumors to endocrine therapy.

  5. 5. Molecular gas in the galaxy M83 : Its distribution, kinematics, and relation to star formation

    Författare :Andreas Andersson Lundgren; Hans Olofsson; John Whiteoak; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular gas; Galaxies; Galaxies individual: M83; Star formation; Galactic dynamics; Astronomy and astrophysics; Astronomi och astrofysik;

    Sammanfattning : The barred spiral galaxy M83 (NGC5236) has been observed in the 12CO J=1–0 and J=2–1 millimetre lines with the Swedish-ESO Submillimetre Telescope (SEST). The sizes of the CO maps are 100×100, and they cover the entire optical disk. The CO emission is strongly peaked toward the nucleus. LÄS MER
