1. 11. Simulations of the Dynamics of Fibre Suspension Flows

   Författare :Stefan B Lindström; Tetsu Uesaka; Myat Htun; Fritz Bark; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fibre; fibre suspension; simulation; paper; papermaking; forming; fibre orientation distribution; fibre flexibility; viscosity; first normal stress difference; fluid flow; simple shear flow; two-way coupling; three-dimensional; Chemical engineering; Kemiteknik; Engineering physics; Teknisk fysik;

   Sammanfattning : A new model for simulating non-Brownian flexible fibres suspended in a Newtonian fluid has been developed. Special attention has been given to include realistic flow conditions found in the industrial papermaking process in the key features of the model; it is the intention of the author to employ the model in simulations of the forming section of the paper machine in future studies.

3. 12. Quadrature rules for boundary integral methods applied to Stokes flow

   Författare :Oana Marin; Anna-Karin Tornberg; Fritz Bark; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

   Sammanfattning :   Fluid phenomena dominated by viscous effects can, in many cases, be modeled by the Stokes equations. The boundary integral form of the Stokes equations reduces the number of degrees of freedom in a numerical discretization by reformulating the threedimensional problem to two-dimensional integral equations to be discretized over the boundaries of the domain.

4. 13. Phosphoinositides control insulin secretion through multiple routes

   Författare :Phuoc My Nguyen; Christina Bark; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phosphoinositides; PI 4 P; PI 4; 5 P2; Ca2 ; optogenetics; VDCC; Sac2; OSBP; OSW-1; cholesterol; membrane contact sites;

   Sammanfattning : Glucose-stimulated insulin secretion from pancreatic beta cells is the sequence of events that starts with glucose uptake and ends with the fusion of insulin granules with the plasma membrane through Ca2+-triggered exocytosis. Phosphoinositides are minor components of all cellular membranes, yet play fundamental roles as regulators of many cellular processes. LÄS MER

5. 14. Varför tiger du? : Expositionen i sju enaktare av August Strindberg

   Författare :Hanif Sabzevari; Björn Meidal; Richard Bark; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; August Strindberg; one-act plays; exposition; The Stronger; Pariah; Simoom; Debit and Credit; The First Warning; Facing Death; Motherly Love; drama; theatre; naturalism; narratology; semiotics; structuralism; Swedish literature; Literature; Litteraturvetenskap;

   Sammanfattning : This is a study of how expository information is presented in the metatext (title, subtitle, prefaces, dedications, the dramatis personae, announcements of act and scene, stage directions etc.) and the dialogue in seven one-act plays by August Strindberg: The Stronger (1889), Pariah (1889), Simoom (1889), Debit and Credit (1892), The First Warning (1892), Facing Death (1892), and Motherly Love (1892).

7. 15. Improving trace metal characterisation of ore deposits – a crucial step towards sustainable mining

   Författare :Mathis Warlo; Christina Wanhainen; Glenn Bark; Alan Butcher; Thomas Riegler; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ore Geology; Malmgeologi;

   Sammanfattning : Sustainable mining, including the utilisation of an ore body to its full potential, is becoming increasingly important for human society as the demand for metals increases. In order to maximise the recovery of useful metals, detailed characterisation of the ore prior to processing is vital. LÄS MER
