2. 1. Inducing large-scale diffusion of innovation : An integrated actor- and system-level approach

   Author : Ingrid Mignon; Anna Bergek; Johanna Nählinder; Volker Hoffmann; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovation; large-scale diffusion; adopters; actor; system; drivers; challenges; motives; strategies; policies; renewable electricity; technology; intermediaries;

   Abstract : In order for the innovation process to be successful, not only do innovations need to be developed and reached the market, but, once they are available for users, they have to spread on a large scale. In the innovation literature, a complete explanation is lacking of why some innovations reach a phase of large-scale diffusion faster than others, including both actor- and system-level components.

4. 2. Effects of surfactant adjuvants on plant leaf cuticle barrier properties

   Author : Anton Fagerström; Malmö högskola; []
   Keywords : Adjuvant; Surfacant; Cuticle; Tebuconazole; Diffusion; Clivia miniata Regel leaf; Model wax; Phase diagram; Hydration; Eutectic melting; Crystalline domains; Softening; Wax film; Quartz Crystal Microbalance with dissipation QCM-D ; Differential Scanning Calorimetry DSC ; Small- and Wide-angle X-ray Diffraction SWAXD ;

   Abstract : I avhandlingen undersöks växelverkan mellan det yttersta lagret på växters blad (cutikeln), aktiva substanser, och ämnen som tillsätts för att öka bekämpningsmedlens effekt, i detta fall vissa former av tensider. Barriären som hindrar upptag av främmande ämnen i växten sitter i cutikeln. READ MORE

5. 3. lac of Time : Transcription Factor Kinetics in Living Cells

   Author : Petter Hammar; Johan Elf; Antoine van Oijen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; gene regulation; transcription factor; lac operon; facilitated diffusion; single molecule imaging; Molecular Biotechnology; Molekylär bioteknik;

   Abstract : Gene regulation mediated by transcription factors (TFs) is essential for all organisms. The functionality of TFs can largely be described by the fraction of time they occupy their regulatory binding sites on the chromosome. DNA-binding proteins have been shown to find their targets through facilitated diffusion in vitro. READ MORE

6. 4. From the Electronic Structure of Point Defects to Functional Properties of Metals and Ceramics

   Author : David Andersson; Börje Johansson; Pavel Korzhavyi; Benjamin Burton; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; first principles; ab initio; density functional theory; Calphad; point defects; diffusion; solid electrolytes; oxygen storage materials; Material physics with surface physics; Materialfysik med ytfysik;

   Abstract : Point defects are an inherent part of crystalline materials and they influence important physical and chemical properties, such as diffusion, hardness, catalytic activity and phase stability. Increased understanding of point defects enables us to tailor the defect-related properties to the application at hand. READ MORE

7. 5. Molecular Metamorphosis in Transcriptional Regulation

   Author : Malin Lüking; Johan Elf; Victor Muñoz; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein-DNA interactions; Facilitated diffusion; Binding Kinetics; Molecular Simulations; Fluorescence Microscopy; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

   Abstract : The foundation of all life is the interaction of molecules. Molecular interaction occurs in the tightly packed cytoplasm. In this crowded environment, the molecules need to be able to establish stable interactions with specific interaction partners, and with specific ones only. READ MORE
