  1. 21. Microscopic Theory of Externally Tunable Exciton Signatures of Two-Dimensional Materials

    Author : Maja Feierabend; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; localized states; density matrix formalism; magnetic field; transition metal dichalcogenides; Bloch equations; organic inorganic heterostructures; dark excitons; strain;

    Abstract : Atomically thin transition metal dichalcogenides (TMDs) are in the focus of current research due to their efficient light-matter interaction and the remarkably strong Coulomb interaction that leads to tightly bound excitons. Due to their unique band structure, TMDs show a variety of bright and optically inaccessible dark excitonic states. READ MORE

  2. 22. Baggy paper webs : Effect of uneven moisture and grammage profiles in different process steps

    Author : Cecilia Land; Lennart Stolpe; Kaarlo Niskanen; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bagginess; drying; calendering; grammage; moisture content; paper; profile; reels; softwood kraft pulp; storage; strain; tension; web; Chemical Engineering; Kemiteknik;

    Abstract : One of the problems encountered in paper converting is caused by the occurrence of "baggy webs", which essentially is when the tension profile of the paper web is uneven. In an area with low tension the paper is longer, which results in bagginess. READ MORE

  3. 23. Job Demands, Job Resources, and Consequences for Managerial Sustainability in the Public Sector – A Contextual Approach

    Author : Linda Corin; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; managerial work; organization; context; psychosocial working conditions; work content; job demands-resources model; managerial sustainability; public sector;

    Abstract : ABSTRACT The aims of this thesis were threefold: to explore and increase knowledge of managerial working conditions in Swedish municipalities, to extend the job demands-resources (JD-R) model, and to provide information that public sector decision-makers and human resources departments can use and apply in promoting sustainable managerial working conditions. The argument in this thesis is that a contextual perspective on managerial work is needed, entailing a shift in focus from managers and their individual differences, to the conditions that public sector managers work under.

  4. 24. Multidimensional MRI  of Myocardial Dynamics : Acquisition, Reconstruction and Visualization

    Author : Andreas Sigfridsson; Hans Knutsson; Sebastian Kozerke; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; Cardiac motion; myocardial dynamics; strain; tensor; deformation; DENSE; k-t BLAST; Medical engineering; Medicinsk teknik;

    Abstract : Methods for measuring deformation and motion of the human heart in-vivo are crucial in the assessment of cardiac function. Applications ranging from basic physiological research, through early detection of disease to follow-up studies, all rely on the quality of the measurements of heart dynamics. READ MORE

  5. 25. Quantitative Electron Microscopy Studies of Metal Nanoparticle Catalysts: Nanostructure, Support Interaction and Ageing Effects

    Author : Torben Nilsson Pingel; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; CO oxidation; strain; ageing; specimen preparation; scanning electron microscopy SEM ; FIB SEM; supported nanoparticle catalyst; transmission electron microscopy TEM ; particle size distribution PSD ; platinum;

    Abstract : Heterogeneous catalysis plays a major role in modern society, for example in chemical production, sustainable energy production and emission control technologies. Metal nanoparticles (NPs) supported on oxide materials are frequent catalytic systems in this field. READ MORE
