1. 31. Systematics and phylogenetics of the Blepharispermum group (Asteraceae - Heliantheae)

   Författare :Torsten Eriksson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fylogeni;

   Sammanfattning : This thesis treats the Blepharispermum group which comprises the three genera Athroisma DC., Blepharispermum Wight ex DC., and Leucoblepharis Arnott. The systematic position of the group within the Asteraceae is discussed, and a transfer is proposed from the tribe Inuleae, where it was placed earlier, to the Heliantheae. LÄS MER

3. 32. Nickel and iridium pincer complexes with saturated frameworks - synthesis and reactivity

   Författare :Klara Jonasson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PCP complexes; aliphatic pincer ligands; coordination; cyclometallation; iridium; nickel; organometallic synthesis; CO2 activation; catalysis;

   Sammanfattning : As the tridentate chelate complexes referred to as pincer complexes have expanded their scope as homogeneous catalysts, there is an increased interest in electronic and steric fine-tuning of such complexes. One accessible variable in this aspect is the hybridisation of any coordinated carbon atoms. LÄS MER

4. 33. The development of synthetic gene delivery systems

   Författare :Lars J Brandén; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :gene transfer; synthetic vector; gene therapy; Bioplex; PNA; NLS;

   Sammanfattning : This thesis describes a new platform technology. The technique is referred to as Bioplex (biological complex) in analogy with the nomenclature for other transfection reagents, since we attach biological functions to a nucleic acid complex via sequence-specific hybridisation.

5. 34. New Public Professional Organisationalism Towards new professional, managerial and cliental roles as exemplified in Swedish schools

   Författare :Sanna Eklund; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; samhällsvetenskap; organisationer; skola; professioner;

   Sammanfattning : This thesis aims to deepen our understanding of public professional organisationalism. Whereas new professionalism is an established concept used to describe changes in the roles of professionals, there is a lack of studies on organisationalism that include the roles of managers and clients.

7. 35. Expression and regulation of vasoactive substances, sex steroids and their receptors in placenta during normal pregnancy and preeclampsia

   Författare :Josefine Nasiell; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Despite intense studies preeclampsia remains enigmatic and a major cause of maternal and fetal morbidity and mortality. It is now widely accepted that the placenta has a central role in preeclampsia; delivery of the placenta is the only known cure. LÄS MER
