  1. 1. Tool steel for tool holder applications : microstructure and mechanical properties

    Author : Anna Medvedeva; Jens Bergström; Birger Karlsson; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tool steel; tool holder; microstructure; mechanical properties; machinability; Materials science; Teknisk materialvetenskap;

    Abstract : Large improvements in cutting tool design and technology, including the application of advanced surface engineering treatments on the cemented carbide insert, have been achieved in the last decades to enhance tool performance. However, the problem of improving the tool body material is not adequately studied. READ MORE

  2. 2. Performance of advanced tool steels for cutting tool bodies

    Author : Anna Medvedeva; Jens Bergström; Pavel Krakhmalev; Staffan Gunnarsson; Volker Schulze; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tool steel; cutting tool body; fatigue strength; stress relaxation; machinability; high-temperature properties; microstructure; Materials science; Teknisk materialvetenskap; Materialteknik; Materials Engineering;

    Abstract : Performance of indexable insert cutting tools is not only about the performance of cutting inserts. It is also about the cutting tool body, which has to provide a secure and accurate insert positioning as well as its quick and easy handling under severe working conditions. READ MORE

  3. 3. Writing a bachelor's thesis in nursing education : A tool for the future

    Author : Ani Henttonen; Margareta Westerbotn; Bjöörn Fossum; Max Scheja; Marianne Teräs; Charlotte Silén; Karolinska Institutet; Karolinska Institutet; Sophiahemmet Högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Writing a bachelor’s thesis is associated with the demonstration of generic, scientific, and transferable knowledge and skills in the main area of studies in their first cycle of higher education. The many goals are challenging for nursing students on the threshold of working life, for whom a bachelor’s thesis is a prerequisite for completion of a threeyear academic education. READ MORE

  4. 4. Cognition in Hearing Aid Users : Memory for Everyday Speech

    Author : Hoi Ning Elaine Ng; Jerker Rönnberg; Mary Rudner; Thomas Lunner; Kevin Munro; Linköpings universitet; []
    Keywords : Hearing aid; working memory; free recall; noise reduction; speech recognition; Hörapparat; arbetsminne; återgivning; brusreducering; taluppfattning;

    Abstract : The thesis investigated the importance of cognition for speech understanding in experienced and new hearing aid users. The aims were 1) to develop a cognitive test (Sentence-final Word Identification and Recall, or SWIR test) to measure the effects of a noise reduction algorithm on processing of highly intelligible speech (everyday sentences); 2) to investigate, using the SWIR test, whether hearing aid signal processing would affect memory for heard speech in experienced hearing aid users; 3) to test whether the effects of signal processing on the ability to recall speech would interact with background noise and individual differences in working memory capacity; 4) to explore the potential clinical application of the SWIR test; and 5) to examine the relationship between cognition and speech recognition in noise in new users over the first six months of hearing aid use.
