1. 1. Superimposition of Contractional Structures in Models and Nature

   Författare :Hongling Deng; Hemin Koyi; Sudipta Sengupta; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; superimposition; progressive deformation; multiple phases; coaxial; non-coaxial; analogue modelling; fold-and-thrust belts; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

   Sammanfattning : Superimposition of contractional structures is widely observed in different scales in the world. Superimposed structures form due to different processes: change in strain accommodation from one type of structure to another during a single progressive shortening; successive coaxial shortening phases separated by an unconformity; superimposition of different non-coaxial shortening phases.

3. 2. The kaleidoscope of communication : Different perspectives on communication involving children with severe multiple disabilities

   Författare :Cecilia Olsson; Siv Fischbein; Mats Granlund; Juliet Goldbart; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; dyadic interaction; pre-symbolic communication; multiple disabilities; system theory; communication process; communication models; Education; Pedagogik;

   Sammanfattning : This thesis consists of six publications presenting a theoretical framework, a methodological proposal and three empirical studies. The aim of the work is; to gain knowledge on how children with severe multiple disabilities communicate with their caregivers, to analyse how different research strategies can add knowledge from different perspectives on communication, and to develop models for analysing and describing the dyadic interaction.

4. 3. Biomarkers in Multiple Sclerosis - Monitoring disease activity and treatment afficacy

   Författare :Lenka Nováková Nyrén; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomarkers; multiple sclerosis; neurodegeneration; inflammation; treatment;

   Sammanfattning : The pathophysiology of multiple sclerosis (MS) is complex with the presence of inflammation and neurodegeneration in all stages of the disease. The disease course, treatment response and outcome are highly variable in MS. LÄS MER

5. 4. Investigating and Enhancing Performance of Multiple Antenna Systems in Compact MIMO/Diversity Terminals

   Författare :Shuai Zhang; Sailing He; Raj Mittra; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiple antennas; planar inverted-F antenna; mutual coupling; slot antenna; compact antenna; mobile antenna; Q factors; antenna array; ultra-wideband UWB antenna; pattern diversity; polarization diversity; user effects; adaptive arrays; chassis mode;

   Sammanfattning : Today, owners of small communicating device are interested in transmitting or receiving various multimedia data. By increasing the number of antennas at the transmitter and/or the receiver side of the wireless link, the diversity/Multiple-Input Multiple-Output (MIMO) techniques can increase wireless channel capacity without the need for additional power or spectrum in rich scattering environments.

7. 5. MRI quantification of multiple sclerosis pathology

   Författare :Russell Ouellette; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Multiple sclerosis (MS) is a chronic neuroinflammatory and neurodegenerative disease and a common cause of neurologic disability. MS pathology is characterized by demyelination, neuroaxonal loss and atrophy. LÄS MER
