  1. 11. How tumour cells hijack apical extrusion and how they can be targeted

    Författare :Weiyingqi Cui; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tissue development and cell behavior are influenced not only by chemical signals but also by physical ones. The responses of cells to mechanical forces can range from the immediate adjustment of cell morphology and motility to long-term genome reorganisation and cell fate changes. LÄS MER

  3. 12. Simulation of Irregular Waves and Wave Induced Loads on Wind Power Plants in Shallow Water

    Författare :Jenny Trumars; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave load; Non-linear wave models; ocean engineering; wind energy converter; perturbation theory; shallow water;

    Sammanfattning : The essay gives a short introduction to waves and discusses the problem with non-linear waves in shallow water and how they effect an offshore wind energy converter. The focus is on the realisation of non-linear waves in the time domain from short-term statistics in the form of a variance density spectrum of the wave elevation. LÄS MER

  4. 13. Konstnärskap i samspel : om skapande arbetsprocesser i myndighetsledda samverkansprojekt

    Författare :Ulrika Florin; Inger Orre; Yvonne Eriksson; Maria Johansson; Mälardalens högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Creative work processes; collaborative projects; sketches; models; presentation; practical knowledge; visual communication; Skapande arbetsprocesser; samverkans projekt; skiss; modell; presentation; praktisk kunskap; visuell kommunikation; Innovation and Design; innovation och design;

    Sammanfattning : Artists in interaction: creation processes in official collaborative projects is a doctoral thesis that explores the creation processes of artists, when the project owner defines the purpose, theme and framework. The area is explored from the artists' perspective and the overall research question deals with the opportunities and obstacles that artists face when working in collaborative projects. LÄS MER

  5. 14. Structural and Functional Studies of Membrane Proteins : From Characterisation of a Fatty Acyl-CoA Synthetase to the Discovery of Superoxide Oxidase

    Författare :Camilla A. K. Lundgren; Martin Högbom; James Imlay; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; biokemi;

    Sammanfattning : This thesis is divided into three parts; the first part describes a method for efficient screening of membrane proteins for crystallography. By utilising the properties of a folding reporter GFP it is possible to quickly and accurately screen the stability of a protein in a range of conditions without full purification. LÄS MER

  7. 15. Mechanistic Studies on Proton-Coupled Electron Transfer from Tyrosine and Tryptophan Derivatives

    Författare :Astrid Nilsen-Moe; Leif Hammarström; Pia Ädelroth; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proton-Coupled Electron Transfer; PCET; Tyrosine; Tryptophan; Amino Acid Radicals; Transient Absorption; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Sammanfattning : Proton-coupled electron transfer (PCET) from tyrosine (Y) and tryptophan (W) is vital to many redox reactions in Nature where PCET between several Ys, or Ws, or between a mix of Ys and Ws can be used to transfer electrons, or protons, or both over large distances of several Å. Studying the PCET reaction mechanisms of Y and W is important for fundamental knowledge, and can help researchers that wish to mimic redox reactions in Nature. LÄS MER
