  1. 1. Epidemiological and experimental studies on sarcoma with focus on gastrointestinal stromal tumors

    Author : Fredrik Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Sarcoma is the common denominator for malignant tumors of mesenchymal origin. Sarcomas encompass almost 100 diagnoses with different histology, molecular features and natural history, and may present in any part of the body. The most common sarcoma in the abdomen is the gastrointestinal stromal tumor (GIST). READ MORE

  2. 2. Spectroscopic studies of InGaAs/GaAs/A1GaAs quantum dots and wires

    Author : Fredrik Karlsson; Manfred Bayer; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : It is demonstrated that the photoluminescence (PL) spectra of single selfassembled lnAs/GaAs quantum dots (QDs) are very sensitive to excitation energy and crystal temperature, which is explained in terms of modulation of the effective diffusivity of the photogenerated carriers affecting the capture probability into theQD. This effect results in a population of the QD with excess electrons, and can be used as a simple tool to create and study charged exciton complexes. READ MORE

  3. 3. The biology of filamentous phage infection - implications for display technology

    Author : Fredrik Karlsson; Institutionen för immunteknologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biotechnology; Bioteknik; infection mechanism; selective infection; TolA; Escherichia coli; pIII; Filamentous phage; Phage display technology;

    Abstract : Phage display technology is a biotechnological tool that can be used to obtain molecules/reagents able to discriminate between target molecules. Reagents with such features can be used in diverse settings like biological chemistry, diagnostics and in therapeutic applications. READ MORE

  4. 4. Method configuration : method and computerized tool support

    Author : Fredrik Karlsson; Linköpings universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Informationssystem; Information storage and retrieval systems; Computer science; Datavetenskap;

    Abstract : In this dissertation, method configuration is treated as a kind of method engineering, focusing on adaptation of a base method. A conceptual framework, a meta-method and a computerized tool support for method configuration are proposed. READ MORE

  5. 5. The acquisition of contrast : a longitudinal investigation of initial s+plosive cluster development in Swedish children

    Author : Fredrik Karlsson; Kirk P. H. Sullivan; Peter E. Czigler; Marilyn M. Vihman; Umeå universitet; []
    Keywords : HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; phonological contrast; speech development; place and manner of articulation; aspiration; structural complexity; acoustic cues; homonym production; Phonetics; Fonetik;

    Abstract : This Thesis explores the development of word-initial s+plosive consonant clusters in the speech of Swedish children between the ages of 1;6 and 4;6. Development in the word-initial consonant clusters is viewed as being determined by 1) the children’s ability to articulate the target sequence of consonants, 2) the level of understanding of which acoustic features in the adult model production are significant for the signalling of the intended distinction, and 3) the children’s ability to apply established production patterns only to productions where the acquired feature agrees with the adult target, to achieve a contrast between rival output forms.
