Bostadsbränder och sprinkler. En koppling till brandteknisk dimensionering

The aim of this study was to develop a model for the quantification of the occupant risk in residential fires. The model should make it possible to quantitatively evaluate which effect the presence of a residential sprinkler has on the fire development. Statistics on causes and outcomes of residential fires were used as background material for the model development. A literature review was carried

Risk of contact allergy and dermatitis at a wind turbine plant using epoxy resin-based plastics

Aims: To identify workplace and individual risk factors for occupational contact allergy and dermatitis. Methods: A cross-sectional study was carried out at an international company producing wind turbine systems in Denmark. A cohort of 724 production workers at four facilities was highly exposed to epoxy resin as well as other chemicals. A screening questionnaire (participation rate 84.7%) was fo

Multivariate data analysis of dynamic amperometric biosensor responses from binary analyte mixtures - application of sensitivity correction algorithms

In this paper, it is demonstrated that a single-receptor biosensor can be used to quantitatively determine each analyte in binary Mixtures LIS in multivariate data analysis tools based on the dynamic responses received from flow injection peaks. Mixtures with different concentrations of two phenolic compounds, catechol and 4-chlorophenol, were measured with a graphite electrode modified with tyros

Constraining the very heavy elemental abundance peak in the chemically peculiar star χ Lupi, with new atomic data for Os II and Ir II

The determination of elemental abundances plays an important role inunderstanding the atmospheric processes that lead to anomalies inspectra of chemically peculiar stars. Ongoing study of the HgMn star χ Lupi has defined much of the elemental abundance distribution but progress is dependent upon the availability and accuracy of the atomic data. Here we present experimentally determined wavelengths

Prussian blue modified glassy carbon electrodes - Study on operational stability and its application as a sucrose biosensor

Stabilisation of electrochemically deposited Prussian blue (PB) films on glassy carbon (GC) electrodes has been investigated and an enhancement in the stability of the PB films is reported if the electrodes are treated with tetrabutyl ammonium toluene-4-sulfonate (TTS) in the electrochemical activation step following the electrodeposition. A multi-enzyme PB based biosensor for sucrose detection wa

The middle Cambrian Ptychagnostus punctuosus and Goniagnostus nathorsti zones in Vastergotland, Sweden

New trilobite discoveries from eight localities in Vastergotland, south-central Sweden, demonstrate that the middle Cambrian Ptychagnostus punctuosus and Goniagnostus nathorsti zones are present in most Lower Palaeozoic outcrop areas of Vastergotland, though as a thin and impersistent conglomeratic limestone, up to approximately 15 cm thick. These zones have not previously been recognised in Vaste

Numerical Prediciton of Heat Flux from Flame in Room Fire

A number of CFD (Computational Fluid Dynamics) calculations were carried out to simulate the large scale room corner fire, which is an important scenario for the evaluation of the fire performance of the surface lining material. Considered are turbulent gas flows, turbulent combustion, radiation and heat conduction inside solid boundary. Heat transfer from flame and hot gas is calculated, with the

Maternal drug use in early pregnancy and infant cardiovascular defect

The purpose of the paper is to identify maternal drug use that may be associated with an increased risk for cardiac defects in the offspring. A case-control study was performed with cases (cardiovascular defects without known chromosome anomalies) being identified from three Swedish health registers (n = 5015) and controls being all infants born in Sweden during the period 1 July 1995-2001 (n = 57

Extensive acute deep vein thrombosis of the iliocaval segment: midterm results of thrombolysis and stent placement.

PURPOSE: To evaluate patency and clinical outcome in patients treated with catheter-directed thrombolysis and stent placement for acute extensive thrombosis affecting the iliocaval segment. MATERIALS AND METHODS: During a 10-year period (1994-2005), 37 patients with 44 limbs (26 female, median age 31 years) with acute extensive venous thrombosis affecting the iliocaval segment were treated with ca

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
