1. 16. Public procurement of engineering services : Task characteristics, control modes and effects on adaptability

   Författare :Klara Granheimer; Tina Karrbom Gustavsson; Per-Erik Eriksson; Göran Lindahl; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; client; construction management; engineering services; organizational control; public procurement; beställare; infrastrukturprojekt; offentlig upphandling; organisationsteori; tekniska konsulttjänster; Real Estate and Construction Management; Fastigheter och byggande;

   Sammanfattning : Previous research has emphasized the importance of engineering services and adaptability in the early stages of construction projects. Public clients usually procure engineering services from private companies, which makes their procurement strategies important in creating incentives for adaptability and innovation for the service providers.

3. 17. Allosteric modulation of pentameric ligand-gated ion channels by general anesthetics

   Författare :Stephanie A. Heusser; Erik Lindahl; Pierre-Jean Corringer; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; biokemi;

   Sammanfattning : Pentameric ligand-gated ion channels (pLGICs) are key components of fast synaptic transmission and are targets of neuroactive drugs such as benzodiazepines, alcohol and muscle relaxants. Although early theories of general anesthesia suggested non-specific lipid interaction as the mechanism of anesthetic action, it has now become evident that they too bind to pLGICs. LÄS MER

4. 18. Solvation properties of proteins in membranes

   Författare :Anna CV Johansson; Erik Lindahl; Mounir Tarek; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane protein; lipid bilayer; free energy; solvation; insertion; molecular dynamics simulations; protein mass fraction; Theoretical chemistry; Teoretisk kemi; Biochemistry; biokemi;

   Sammanfattning : Knowledge about the insertion and stabilization of membrane proteins is a key step towards understanding their function and enabling membrane protein design. Transmembrane helices are normally quite hydrophobic to insert efficiently, but there are many exceptions with unfavorable polar or titratable residues. LÄS MER

5. 19. Molecular Processes in Dynamic Wetting : Du som saknar dator/datorvana kan kontakta Cathrine Bergh, [email protected] för information

   Författare :Petter Johansson; Berk Hess; Erik Lindahl; Guillaume Galliero; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; contact lines; nanodroplets; computational physics; molecular dynamics; fluid dynamics; multi-phase flows; electrowetting; Biologisk fysik; Biological Physics;

   Sammanfattning : The spreading of liquids onto and over surfaces is a fundamental process in nature. It is present in all forms and sizes: From rivers carving through landscapes, to our blood stream transporting nutrients to cells, and even single water molecules moving through channels into these cells.

7. 20. Novel Analysis Toolkit for Capillaroscopic Images: Development and Clinical Evaluation

   Författare :Abdolamir Karbalaie; Björn-Erik Erlandsson; Olof Lindahl; KTH; []
   Nyckelord :Nailfold videocapillaroscopy; Image enhancement; Inter and intra-observer reliability; Tillämpad medicinsk teknik; Applied Medical Technology;

   Sammanfattning : Nailfold capillaroscopy (NC) is an invasive imaging technique that is used to assess the blood capillary network in the nailfold area. NC is routinely used for patients with microcirculation problems, such as systemic sclerosis and other connective tissue diseases. NC is repeatable and appears to be simple and harmless. LÄS MER
