  1. 1. Small-Animal Imaging with Liquid-Metal-Jet X-Ray Sources

    Författare :Daniel Larsson; Hans Hertz; Anna Burvall; David Paterson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray; x-ray imaging; small animal; phase contrast; tomography; Fysik; Physics;

    Sammanfattning : Small-animal x-ray imaging is an important tool for medical research. The penetration power of x-rays makes it possible to investigate the 3D structure of small animals and other thick biological samples by computed tomography (CT). LÄS MER

  3. 2. Thermoresponsive cellulose-based composites by polymer modification

    Författare :Emma Larsson; Anna Carlmark Malkoch; Lian Hutchings; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Sammanfattning : The interest in utilizing cellulose based materials has grown rapidly in recent years, due to the growing environmental concerns about utilizing fossil based material. One potential application of cellulose is in thermoresponsive materials, which are attracting attention due to their ability of altering conformation when exposed to changes in external temperature.

  4. 3. Toward increased applicability of ultrasound contrast agents

    Författare :Malin Larsson; Lars-Åke Brodin; Anna Bjällmark; Kenneth Caidahl; Jan Engvall; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contrast agent; Contrast-to-tissue-ratio; Echocardiography; Endocardial border; Microbubbles; Multimodal; Phantom; Polymer; Ultrasound; Wall motion score index.; Teknik och hälsa; Technology and Health;

    Sammanfattning : Ultrasound is one of the most widely used modalities in medical imaging because of its high cost-effectiveness, wide availability in hospitals, generation of real-time images, and use of nonionizing radiation. However, the image quality can be insufficient in some patients. LÄS MER

  5. 4. Military Leaders and Trust

    Författare :Maria Fors Brandebo; Gerry Larsson; Renée Perrin-Wallqvist; Misse Wester; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; military leadership; trust; destructive leadership; constructive leadership; Destrudo-L; Ledarskap under påfrestande förhållanden; Ledarskap under påfrestande förhållanden; Psykologi; Psychology;

    Sammanfattning : The aim of this thesis is to study trust in military leaders. Empirical data was gathered through interviews and questionnaires with military personnel mostly from Sweden, but also from four other European countries. LÄS MER

  7. 5. Strategies for improved Escherichia coli bioprocessing performance

    Författare :Johan Jarmander; Gen Larsson; Thomas Egli; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; E. coli; Salmonella; surface expression; autotransport; AIDA-I; lignocellulose; glucose; xylose; arabinose; simultaneous uptake; 3HB; Bioteknologi; Biotechnology;

    Sammanfattning : Escherichia coli has a proven track record for successful production of anything from small molecules like organic acids to large therapeutic proteins, and has thus important applications in both R&D and commercial production. The versatility of this organism in combination with the accumulated knowledge of its genome, metabolism and physiology, has allowed for development of specialty strains capable of performing very specific tasks, opening up opportunities within new areas.
