  1. 1. Organic Azides : Functional Molecules and Materials

    Författare :Giampiero Proietti; Peter Dinér; Per I. Arvidsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; perfluorinated Aromatic Azide; Photoactivatable; fluorophores; aggregation-induced emission; sulfonimidamides; sulfoximes; chiral auxilary; organogel; azides reduction; Ni-B; Kemi; Chemistry;

    Sammanfattning : The work presented in this thesis stems from the chemistry of the azido group, and more specifically from the unique reactivity of perfluorinated aromatic azides and how to use this reactivity to access new types of molecules to enable new applications in asymmetric synthesis and materials.In the first section of this thesis, a photoactivatable fluorescence probe is presented, where the non-luminescent azide was activated via a UV-light-promoted intramolecular N–H insertion reaction forming a fluorescence emitter.

  2. 2. Conformational Stability!? : Synthesis and Conformational Studies of Unnatural Backbone Modified Peptides

    Författare :Anna S. Norgren; Per I. Arvidsson; Norbert Sewald; Uppsala universitet; []
    Nyckelord :Organic chemistry; Conformational investigations; β-peptides; glycosylation; biomolecular recognition; cyclic β³-peptides; cyclic mixed α β²-peptides; β-peptoids; Organisk kemi;

    Sammanfattning : The beauty of the wide functionality of proteins and peptides in Nature is determined by their ability to adopt three-dimensional structures. This thesis describes artificial molecules developed to mimic secondary structures similar to those found crucial for biological activities. LÄS MER

  3. 3. Styrning med belöningssystem : två fallstudier om effekter av belöningssystem som styrmedel

    Författare :Per Arvidsson; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : För att kunna drivas effektivt och överleva på lång sikt har företagen blivit alltmer beroende av sina medarbetare, deras kompetens, ansvar, värderingar och, inte minst, motivation. Hur kan individerna bringas till att arbeta på ett sådant sätt som ligger i linje med verksamhetens mål? Belöningssystem är ett styrmedel som premierar (och sanktionerar) medarbetarnas beteenden och prestationer. LÄS MER

  4. 4. Physiological aspects on intracardiac blood flow

    Författare :Per Arvidsson; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; 4D flow; physiology; cardiac development; kinetic energy; hemodynamic force; vortex ring formation;

    Sammanfattning : Magnetic resonance imaging enables detailed in vivo study of complex flow through 3D, time-resolved phase contrast imaging (4D flow). 4D flow may reveal previously unknown aspects of the physiology of intracardiac blood flow, and possibly elucidate pathophysiological processes that have yet to manifest themselves outside the heart.

  5. 5. Priority Setting and Rationing in Primary Health Care

    Författare :Eva Arvidsson; Per Carlsson; Lars Borgquist; Malin André; Magne Nylenna; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Background: Studies on priority setting in primary health care are rare. Priority setting and rationing in primary health care is important because outcomes from primary health care have significant implications for health care costs and outcomes in the health system as a whole.
