1. 11. Striking a balance : Managing collaborative multitasking in computer-supported cooperation

   Författare :Rikard Harr; Victor Kaptelinin; Mikael Wiberg; Oskar Juhlin; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer-supported Cooperative Work; articulation work; individual task execution; balance; interruptions; availability; awareness; interaction; information technology; multitasking; task switching; Informatics; computer and systems science; Informatik; data- och systemvetenskap;

   Sammanfattning : This thesis is a collection of six papers and a cover paper reporting an exploration of how to strike a balance between individual task execution and work articulation in Computer-supported Cooperative Work (CSCW). The interest in this theme is motivated by an increased reliance of IT-supported cooperative work arrangements in modern organizations, the fragmented layout of work for multitasking individuals and reports on various forms of overload, increased level of stress and anxiety experienced by workers active in these organizations.

3. 12. Regulation of Immunoglobulin Isotype Switching and of the Germinal Center Response

   Författare :Minghui He; Eva Severinson; Jayanta Chaudhuri; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; immunologi; Immunology;

   Sammanfattning : After stimulation, B cells can undergo two types of genetic alteration in their immunoglobulin (Ig) genes: somatic hypermutation and class switch recombination (CSR), both of which are initiated by activation-induced cytidine deaminase (AID).Although class switching requires cell proliferation, the mechanism is partly unknown.

4. 13. Effect of HV Impulses on Partial Discharge Activity in Oil-Impregnated Paper Insulation

   Författare :Respicius Clemence Kiiza; Hans Edin; Robert Saers; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : High voltage (HV) transients in electrical power systems are mainly caused by lightning strikes and switching operations.  The high voltage transient from its point of origin can propagate in either direction in the electrical power transmission line, and if its magnitude would be below the Basic Insulation Level (BIL) of the equipment for impulse voltage, it can reach the terminals of the equipment without being dissipated by surge arresters.

5. 14. Muscle composition, reach, physical activity and botulinum toxin treatment in children with cerebral palsy

   Författare :Stefan Gantelius; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Cerebral palsy (CP), the most common cause of movement disorders and physical disability in children all over the world, is caused by an injury to the developing brain. Although this injury is not progressive, the manifestations of the disorder change as the child ages. LÄS MER

7. 15. The interaction of light and magnetism in the TbxCo100-x system

   Författare :Agne Ciuciulkaite; Vassilios Kapaklis; Pablo Maldonado; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetism; rate-earth transition metal alloys; light-magnetism interaction; all-optical switching; Fysik; Physics;

   Sammanfattning : Development of the faster and denser magnetic memory storage elements has been an active area of research since early 20th century. The path of research on magnetization manipulation began with firstly changing the magnetization state of a medium in an external magnetic field, then heating of a medium and magnetizing with a permanent magnet was explored, while the latest efforts have been focused on switching the magnetization only by a polarized laser light.
