  1. 16. Producing, Preventing, and Explaining Persistent Complex Subliminal Stimulation Effects

    Författare :Andreas Birgegård; Staffan Sohlberg; Mario Mikulincer; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Subliminal stimuli; persistent effects; attachment; relational schema; ethics; debriefing; interaction; motivation; sex differences; Psykologi; Psychology; Psykologi;

    Sammanfattning : Strong recent focus on unconscious processes has increased interest in subliminal stimulation and similar experimental technologies. Assumptions about the persistence of effects of unconscious stimulation are generally conservative, referring to seconds or minutes (Silverman, 1977; Velmans, 1991). LÄS MER

  3. 17. Ontogeny of perception of maternal and nosocomial stimuli in infants

    Författare :Jakob Frie; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Preterm born infants in neonatal units experience unusual sensory inputs that can shape and nurture their developing brains differently from full-term healthy newborn infants. To improve the care of preterm infants and their neurodevelopmental outcomes, we need to understand how the brain functions at different developmental stages and implement this knowledge into clinical care and follow-up programs.

  4. 18. Nanoparticles for multifunctional drug delivery systems

    Författare :Jian Qin; Mamoun Muhammed; Paavo K J Kinnunen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; drug delivery; stimuli-sensitive; SPION; PLLA; PNIPAAm; gold; MRI; cytotoxicity; Pluronic; phase transfer; Materials chemistry; Materialkemi;

    Sammanfattning : Multifunctional drug delivery systems incorporated with stimuli-sensitive drug release, magnetic nanoparticles and magnetic resonance (MR) T2 contrast agents is attracting increasing attention recently. In this thesis, works on polymer nanospheres response to temperature change, superparamagnetic iron oxide nanoparticles (SPION)/polymeric composite materials for MR imaging contrast agents are summarized.

  5. 19. Tailoring Surface Properties of Bio-Fibers via Atom Transfer Radical Polymerization

    Författare :Josefina Lindqvist; Eva Malmström; Steven Rannard; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cellulose; bio-fiber; atom transfer radical polymerization; surface modification; grafting; polymer brushes; functional surfaces; superhydrophobic; stimuli-responsive; Polymer chemistry; Polymerkemi;

    Sammanfattning : The potential use of renewable, bio-based polymers in high-technological applications has attracted great interest due to increased environmental concern. Cellulose is the most abundant biopolymer resource in the world, and it has great potential to be modified to suit new application areas. LÄS MER

  7. 20. Ionic Circuits for Transduction of Electronic Signals into Biological Stimuli

    Författare :Klas Tybrandt; Magnus Berggren; Edwin Jager; Janos Vörös; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Modern electronics has revolutionized the way information is processed and stored in our society. In health care and in biology it is of great interest to utilize technology to regulate physiology and to control the signaling pathways. LÄS MER
