Leaching of hazardous substances from additives and admixtures in concrete

The aim of this work was to study the leaching of hazardous substances in additives and admixtures that are commonly contained in concrete. Time-dependent leaching has been analyzed for three types of metal containing concretes: with ordinary Portland cement (OPC), fly ash, and slag. The concretes had uniform leaching patterns, clearly above detection limits. The prolonged diffusion test of 1,700

Ultrasonic Methods for 2D Arterial Wall Movement Measurements

Popular Abstract in Swedish Hjärt- och kärlsjukdomar är den största enskilda orsaken till en för tidig död i västvärlden. För att öka kunskapen om dessa sjukdomar är det viktigt att finna mätmetoder, gärna icke-invasiva, som kan användas för att studera tidiga yttringar av hjärt- och kärlsjukdomar. Förändringar av de mekaniska egenskaperna i artärerna kan vara en sådan tidig yttring. För att få etCardiovascular diseases constitute the major cause of morbidity and mortality in the Western World. To increase our knowledge of cardiovascular diseases, it is important to find methods, preferably non-invasive ones, to study very early manifestations of vascular disease. Changes in the mechanical properties of the arteries can be an early manifestation of vascular disease. Further, changes in the

The Fallen World in Coleridge’s Poetry

This study examines the motif of the Fallen World in Coleridge’s major poems The Ancient Mariner, Christabel and Kubla Khan . The use of Milton’s Paradise Lost as an intertextual foil throughout allows themes and metaphors inherent in the Fallen World motif to emerge in Coleridge’s poetry. A Fall presupposes a standard from which one has been separated downwards. Primarily, it is understood as man

Characterisation of a cluster of TRIM-B30.2 genes in the chicken MHC B locus

We have identified and characterised a cluster of six TRIM-B30.2 genes flanking the chicken BF/ BL region of the B complex. The TRIM-B30.2 proteins are a subgroup of the TRIM protein family containing the tripartite motif ( TRIM), consisting of a RING domain, a B-box and a coiled coil region, and a B30.2-like domain. In humans, a cluster of seven TRIM- B30.2 genes has been characterised within the

Ethics and vaccination

Background: Immunization programmes are ethically defensible and society has a significant role to play in providing vaccination against measles and safeguarding herd immunity to optimize its individuals' capabilities. Since preventive actions interfere with individuals who consider themselves as healthy, public health strategies - as distinct from advice in a clinical consultation - require somet

Simulation of the effect of a reinforcement fibre on network mechanics

Computer simulations were used to study the effect of a single reinforcement fiber added to a mechanical fibre network. The stresses of the surrounding fibers and inter-fiber bonds increased proportionally to the logarithm of the elastic stiffness of the reinforcement fibre. In the case of fiber failure the breaking stress of the model system increased only little and breaking strain decreased lit
