Objective: To test the hypothesis that sub-optimal factors in perinatal care services resulting in perinatal deaths were more common among immigrant mothers from the Horn of Africa, as compared to Swedish mothers. Design: A perinatal audit, comparing cases of perinatal deaths among children of African immigrants residing in Sweden, with a stratified sample of cases among native Swedish women. Se

The integrating properties of the atmospheric boundary layer allow the influence of surface exchange processes on the atmosphere to be quantified and estimates of large-scale fluxes of trace gases and plant isotopic discrimination to be made. Five flights were undertaken over two days in and above the convective boundary layer (CBL) in a vegetated region in central Siberia. Vertical profiles of CO

The fluorescence of single chains of the conductive polymer poly [2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene vinylene] (MEH-PPV) was studied by means of single-molecule spectroscopy at 15 K. MEH-PPV was deposited onto a surface from a toluene solution and covered with a polymer cap layer of poly(vinyl alcohol) spin-coated from an aqueous solution for protection against air. Because MEH-PPV is in

OBJECTIVE: To study whether measurements of wall mechanics can be used as an indicator of disturbed vessel wall integrity and predictor of vessel fragility in Ehlers-Danlos Syndrome (EDS). METHODS: The wall mechanics of the abdominal aorta (AO) and common carotid artery (CCA) were estimated from the indices Ep (pressure strain elastic modulus) and stiffness (beta) in twelve individuals with EDS of

The ability to predict clinical image quality from physical measures is useful for optimization in diagnostic radiology. In this work, clinical and physical assessments of image quality are compared and correlations between the two are derived. Clinical assessment has been made by a group of expert radiologists who evaluated fulfillment of the European image criteria for chest and lumbar spine rad

Type 2 diabetes (T2D) is a serious condition of growing proportions. Developing via an increasing imbalance between insulin sensitivity in the peripheral tissues and insulin release from pancreatic beta-cells, it ultimately renders the individual incapable of regulating the blood glucose concentration, e.g. after a meal. The increased prevalence of T2D is associated with an increase in the prevale

Knowledge of the mechanisms behind prey selection in piscivorous fish is important for our understanding of the dynamics of freshwater systems. Prey selection can involve active predator choice or be a passive process. We experimentally studied size-selectivity in pikeperch, feeding on roach and rudd. When given a choice of different prey sizes, pikeperch selected small prey. Passive selection mec

The selectivity for the glycon part of a donor substrate of beta-glycosidases from almond, a mesophilic (Kluyveromyces fragilis) and three highly thermophilic organisms (Caldocellum saccharolyticum, Sulfolobus solfataricus and Pyrococcus furiosus) was investigated at various temperatures (25-90 degreesC ). On the basis of kinetic constants, the selectivity was calculated as the specificity constan

Hemostasis initiates angiogenesis-dependent wound healing, and thrombosis is frequently associated with advanced cancer. Although activation of coagulation generates potent regulators of angiogenesis, little is known about how this pathway supports angiogenesis in vivo. Here we show that the tissue factor (TF)-VIIa protease complex, independent of triggering coagulation, can promote tumor and deve

The present focus on embodiment in cognitive science undervalues concepts such as convention/norm, representation and consciousness. I argue that these concepts constitute essential properties of language, and this makes it problematic for “embodiment theories” to account for human language and cognition. These difficulties are illustrated by examining a particular, highly influential approach to

This thesis describes an extended flamelet approach for modelling of soot formation in turbulent hydrocarbons diffusion flames. Detailed chemical kinetic mechanisms are used to compute species concentrations, temperature, density and soot formation rates as functions of flamelet coordinates in the space of mixture fraction and scalar dissipation rate. An ensemble average based on a presumed probab

The main functions of viral capsids are to protect, transport and deliver their genome. The mechanical properties of capsids are supposed to be adapted to these tasks. Bacteriophage capsids also need to withstand the high pressures the DNA is exerting onto it as a result of the DNA packaging and its consequent confinement within the capsid. It is proposed that this pressure helps driving the genom
