  2. 1. Essays on Measurement Error and Nonresponse

    Author : Fredrik Johansson; Anders Klevmarken; Per Johansson; Markus Jäntti; Uppsala universitet; []
    Keywords : Economics; Nationalekonomi;

    Abstract : Essay 1 deals with measurement errors. Matching survey data with administrative records provides unique opportunities to evaluate the statistical properties of respondents' answers. This paper focuses primarily on home ownership and wealth variables. READ MORE

  4. 2. The synthesis of chiral bidentate (N,N), (N,P) and (N,O) ligands and their use in metal-mediated asymmetric carbon-carbon bond formation

    Author : Fredrik Johansson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi; organisk kemi; Organic Chemistry;

    Abstract : This thesis covers three projects based on the metal-mediated formation of new chiral centers in the prescence of chiral ligands. The first project, involving (N,N)- ligands, concerns the synthesis of some (C2-symmetric bis(aziridine) ligands and the use of these in the addition of organolithium reagents to N-aryl protected imines leading to enantioselectivities of up to 89%.

  6. 4. Core-hole Clock Spectroscopy Using Hard X-rays : Exciting States in Condensed Matter

    Author : Fredrik Johansson; Andreas Lindblad; Carla Puglia; Tomas Edvinsson; Marc Simon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; core-hole clock; resonant Auger; XPS; black phosphorous; TMDC; perovskite; graphene; coincidences spectroscopy; synchrotron radiation; HAXPES;

    Abstract : This thesis is about how electrons move from one place to another, that is charge transfer dynamics. Charge transfer dynamics is an important property governing chemical and physical changes that form the base for many applications such as electronics, optoelectronics and catalysis. READ MORE

  7. 5. Screening for Candidate Brain Tumor Genes : Identifying Genes that Cooperate with Platelet-Derived Growth Factor in Glioma Development and Progression

    Author : Fredrik Johansson; Bengt Westermark; Leif Carlsson; Uppsala universitet; []
    Keywords : Pathology; PDGF; insertional mutagenesis; retroviral tagging; common insertion site; glioma; expression; cGMP-dependent protein kinase II; Patologi;

    Abstract : Malignant primary brain tumors, gliomas, often overexpress both platelet-derived growth factor (PDGF) ligands and receptors providing an autocrine and/or paracrine boost to tumor growth. Glioblastoma multiforme (GBM) is the most frequent glioma. Its aggressive and infiltrative growth renders it extremely difficult to treat. READ MORE
