2. 1. Studies on spinach plastocyanin and mutants : Expression in Escherichia coli, folding and function

   Author : Mikael Ejdebäck; Örjan Hansson; Miguel A. De la Rosa; Göteborgs Universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; plastocyanin; electron transfer; copper; protein-protein interactions; protein expression; folding; site-directed mutagenesis; NMR; Naturvetenskap; Natural sciences;

   Abstract : Photosynthesis is a process in which photons from sunlight excite chlorophylls in the thylakoid membranes of plants, algae and cyanobacteria. The photo-oxidised reaction centre chlorophyll P700 is re-reduced by an electron transferred from the soluble, blue copper protein plastocyanin. READ MORE

4. 2. In search of a biosensor for DNT detection : Studies of inducer response and specificity of DntR

   Author : Rosa Lönneborg; Peter Brzezinski; Ray Dixon; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; DntR; transcriptional regulation; gfp; nitro-aromatic compounds; LysR family; LTTR; TNT; DNT; FACS; directed evolution; random mutagenesis; recombination; structure determination; biokemi; Biochemistry;

   Abstract : The primary aim of the work presented in this thesis was to change the inducer specificity of the DntR protein in order to improve the response to DNT. The long-term goal is to use this protein in a biosensor for DNT, a signature compound for detection of the explosive TNT. READ MORE

5. 3. Personas and Scenarios in Use

   Author : Rosa Gudjonsdottir; Yngve Sundblad; Henrik Artman; Jonathan Grudin; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ethnographic fieldwork; multi-sited fieldwork; participant observation; user-centered design; user research; personas; scenarios; Computer science; Datalogi; Social anthropology ethnography; Socialantrolopologi etnografi;

   Abstract : Personas are fictitious characters that represent the needs of the intended users, and scenarios complementing the personas describe how their needs can be met. The present doctoral thesis considers the usage of personas and scenarios and how they are used in system development projects. READ MORE

6. 4. On the Anarchic Organisation of Cinematic Spaces : Evoking Spaces beyond Cinema

   Author : Rosa Barba; Konsthögskolan i Malmö; []
   Keywords : HUMANIORA; HUMANITIES; Cinema; Astronomy; Fictional Library; Film; Flicker; Material; New Machine; Autonomy; Embarking; Collective Performances; Public; Auditorium; Space;

   Abstract : This research engages with the space beyond cinema and comprises a futuristic vision about the condition of cinema.My work takes a conceptual approach that considers cinema in an architectural sense and as an instrument, where the environment, the screen, and the projection can be combined or pushed forward to create another spatiotemporal dimension that is concurrent with and beyond the context of interior or exterior space.

7. 5. LiFeSO4F as a Cathode Material for Lithium-Ion Batteries : Synthesis, Structure, and Function

   Author : Adam Sobkowiak; Fredrik Björefors; Kristina Edström; Anna Andersson; M. Rosa Palacin; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Li-ion battery; cathode; LiFeSO4F; tavorite; triplite; synthesis; performance; structure; coating; PEDOT; XRD; Mössbauer spectrocopy; SEM; TEM; electrochemistry; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Abstract : In this thesis, two recently discovered polymorphs of LiFeSO4F, adopting a tavorite- and triplite-type structure, were investigated as potential candidates for use as cathode materials in Li-ion batteries. The studies aimed at enriching the fundamental understanding of the synthetic preparations, structural properties, and electrochemical functionality of these materials. READ MORE
