From gesture in conversation to visible action as utterance

Language use is fundamentally multimodal. Speakers use their hands to point to locations, to represent content and to comment on ongoing talk; they position their bodies to show their orientation and stance in interaction; they use facial displays to comment on what is being said; and they engage in mutual gaze to establish intersubjectivity. This volume brings together studies by leading scholars

Quasi-Lie Algebras and Quasi-Deformations. Algebraic Structures Associated with Twisted Derivations

This thesis introduces a new deformation scheme for Lie algebras, which we refer to as ?quasi-deformations? to clearly distinguish it from the classical Grothendieck-Schlessinger and Gers-tenhaber deformation schemes. The main difference is that quasi-deformations are not in gene-ral category-preserving, i.e., quasi-deforming a Lie algebra gives an object in the larger catego-ry of ?quasi-Lie alge

Synthesis of Optically Active Bicyclo[2.2.2]octane Derivatives - A Study Towards Novel Taxol Mimics and Development of New Chiral Ligands for Asymmetric Catalysis

This thesis is a summary of six papers which concern synthesis of optically active bicyclo[2.2.2]octane derivatives. The derivatives prepared are important building blocks in a study towards a possible replacement of the diterpenoidic part of taxol, (baccatin III), so as to construct a taxol mimic. Some of the derivatives have also been developed into new bidentate ligands. TitaniumIV complexes of

Spinal Cord Injuries

Spinal cord injury can be classified as traumatic and non-traumatic. The traumatic spinal cord injuries (SCI) are caused by motor vehicle accidents (56 %), falls (14 %), firearm and violence-related (16.6 %) and sports injuries (7 %) [1]. Injuries after falls and minor trauma are more commonly seen in elderly patients as they more often have spondylosis and osteoporosis. Violence is more common in

Utvärdering av gästföreläsare

I många kurser anlitas gästföreläsare. Är de värda vad de kostar? Föreläser exempelvis alltid en inbjuden professor på den professorsnivå hon/han får betalt för? Vi anlitar även gästföreläsare från näringslivet för att höja trovärdigheten och kvalitén på våra kurser, men hur väl gör de egentligen detta? Dessa frågor har väkts hos oss under de år vissa av oss kontinuerligt betalat ut arvoden för un

The object of verbs like help and an apparent violation of UTAH

This paper discusses verbs like help, that takes dative case on its object in the Germanic languages with morphological case. In this paper I discuss whether the loss of morphological case in English and mainland Scandinavian had any influence on the argument structure of the VP headed by help-type of verbs.

Presentation of Salmonella antigens by dendritic cells

Popular Abstract in Swedish Tyfoidfeber är en sjukdom som orsakas av bakterien Salmonella typhi. Denna bakterie, som sprids via vatten eller föda, orsakar buksmärtor, feber och illamående. Om infektionen inte behandlas med antibiotika, kan bakterien sprida sig till blodet och leda till döden. Årligen rapporteras 16 miljoner fall av salmonella i världen och av dessa får ungefär 600 000 dödlig utgånThis study investigates the interaction between dendritic cells (DC) and the Gram negative intracellular bacterium Salmonella typhimurium. Using in vitro and in vivo approaches, the capacity of DC to directly and indirectly present antigens from Salmonella-infected cells, cytokine production by infected DC, and activation of bacteria-specific T cells was analyzed. These studies revealed differenti
