This text contains an overview of the field of frost and salt-frost resistance of concrete. It consists of three parts: First, a summary of known phenomena of frost and salt frost deterioration of concrete, then a description of thermodynamics of ice formation in porous materials, and finally a description of proposed models and mechanisms of deterioration during frost and salt frost attack. The c

Popular Abstract in Swedish Denna avhandling berör storskalig genetisk variation och fylogeni hos arterna i växtsläktet Alisma (svaltingar). Den naturliga utbredningen för detta släkte av vatten- eller sumpväxter inskränker sig till norra halvklotets tempererade områden. Den vanligaste arten i större delen av Europa är Alisma plantago-aquatica (svalting eller kranssvalting som den ibland också kalIn the present thesis the phylogeny and patterns of genetic diversity of the plant genus Alisma (Alismataceae) were investigated by means of genetic markers (RAPDs, allozymes, and ITS and trnL sequences). Additionally, morphological studies were carried out in paper IV. All species in the genus were found to be closely related to each other and two major groups of diploid taxa were found: one cont

This thesis combines corpus-based, experimental and instrumental methods to investigate how professional speakers of English use prosody to signal important textual boundaries above the sentence level. In an initial study, prosodic features included in the transcriptions of the Spoken English Corpus, or readily derivable from these, are investigated. These include minor and major tone-unit length

Artikeln introducerar bokens tematik. Några exempel: I traditionell kristen skapelsetro manifesteras Guds godhet genom ordning, medan kaos, synd och död är uttryck för onda makter. Också vetenskapen uppfattar traditionellt verkligheten som ordnad i betydelsen regelbunden. Aktuella trender i såväl vetenskap som teologi utmanar dessa tolkningar. Kaosteori visar att vår traditionella tolkning av såvä

Shippers can play a key role in addressing the environmental impact of transport by placing environmental demands on the transports they operate, or in the process of purchasing transport services. Several research studies of shippers’ environmental initiatives regarding transport have been carried out during the last few years. Research investigations have mapped out environmental actions impleme

Popular Abstract in Swedish Trots att kroppen skyddas av ett hudlager på utsidan och av epitelceller i kroppens inre organ utsätts vi hela tiden för infektioner. När en vävnad blir infekterad börjar cellerna utsöndra inflammatoriska mediatorer som bland annat orsakar svullnad och rodnad. En inflammation kan också orsakas av till exempel slag eller brännskador. De inflammatoriska mediatorerna signaThis thesis describes early inflammatory responses involving interactions between leukocytes and the endothelial lining of the blood vessel wall. An adhesion molecule, E-selectin, which is upregulated on interleukin-1 activated endothelium, was found to mediate rolling between leukocytes and endothelial cells in vivo. Immunohistochemistry revealed that E-selectin was preferentially expressed in ve
