Durability of concrete in saline environment

Contents: - Systematic collection of field data for service life prediction of concrete structures. - Moisture in marine concrete structures - Studies in the BMV-project 1992-1996. - Scaling resistence of concrete field exposure tests. - Chloride induced corrosion in marine concrete structures. - Chloride threshold values in reinforced concrete. - A new method for determing chloride thresholds as

Fabrication and characterization of a molecular adhesive layer for micro- and nanofabricated electrochemical electrodes

When making nanoelectrodes for applications in liquid cells it is plausible that the less noble metal layer may be negatively affected, i.e. it will be etched away leading to very unstable conditions during operation. Here we describe a dry method to produce such a molecular layer consisting of mercaptopropyltriethoxysilane (MPTS) making it possible to controllable and reproducibly form a covalent

Influence of leukotriene D4 and cyclooxygenase-2 on cell survival

Popular Abstract in Swedish En avgörande skillnad mellan encelliga organismer såsom bakterier och multicellulära som oss själva är behovet av kommunikation och samarbete mellan cellerna. Redan under fosterstadiet måste cellerna meddela sig med varandra avseende var de skall ta vägen och vilka uppgifter var och en skall åta sig. Exempelvis måste en cell fortlöpande få information om huruvida den skThe pro-inflammatory effect of leukotrienes is an important element in the pathogenesis of multiple disorders, including asthma and inflammatory bowel diseases (IBD). A serious concern for IBD patients is the increased risk of developing colorectal cancer and since there seems to be a general connection between inflammation and cancer we hypothesised that LTD4 induced signalling events could be in

Air Traffic Controllers and Incidents: An Explorative Interview Study

An explorative interview study was performed with 21 air traffic controllers having experienced air traffic control incidents (loss of separation between aircraft). The results of the interview study identified the following main factors contributing to the occurrence of incidents: 1) memory malfunctions; 2) concentration problems; 3) distractions; 4) inadequate expectations; 5) deficient phraseol

Transient electromagnetic wave propagation in anisotropic dispersive media

Transient electromagnetic wave propagation in a stratified, anisotropic, dispersive medium is considered. Specifically, the direct scattering problem is addressed. The dispersive, anisotropic medium is modeled by constitutive relations (a 3 3 matrix-valued susceptibility operator) containing time convolution integrals. In the general case, nine different susceptibility kernels characterize the med

Föredömligt folk förvandlar gränsland till Europaland : Bilden av Ukraina i svensk press januari 2004 till mars 2006

I den här uppsatsen bedrivs en narrativ medieanalys av hur den svenska rapporteringen om Ukraina sett ut mellan januari 2004 och mars 2006 utifrån sex rikstäckande tidningar. Genom kvantitativa och kvalitativa metoder och med hjälp av ett ramverk av de teoretiska begreppen stereotyper, berättelser och diskussionen om ”den Andre” i Europa, identifieras och diskuteras ett antal huvudteman i mediebil

Predicted fire behaviour of steels and concrete structures

Analytical modelling has opened the door for fire behaviour prediction of not only building materials as concrete and steel but akso of quite complicated concrete structures in general. This paper reflects some of the progress made within the field. A behaviour model of steel is used for coupling results from steady state and transient sate tests. A recently developed procedure is shown on how to

Terror och tystnad. Sovjetregimens krig mot den egna befolkningen

The book deals two aspects of the Soviet Communist terror history of the years 1918-1953. It is in part an analysis of its events and processes, mechanisms, perpetrators and victims and scholarly debates, and in part an analysis of how the post-terror Soviet Union and Russia have coped with the memory of the misdeeds.
