There is general consensus among road safety researchers that the crash count is not linear with respect to the traffic volume. However, the now-preferred practice of estimating exponents on traffic volume not only results in parameters that cannot be confidently applied in other contexts, but also offers very little insight into the relationship. This paper describes a preliminary investigation o
In this paper we estimate the opportunity cost of children. The underlying theoretical model is represented by a household production model. In the empirical analysis, we consider three different cohorts for men and women born between 1955 and 1970. For the women in the two oldest cohorts, the opportunity cost of two children is estimated to 28-29 per cent of full income, which in monetary terms i
We have evaluated capacitive and thermal transducers for recognition of bio- molecular interactions with different analytes. These assays were made in flow analysis systems because of the simplicity such methods provide. A capacitive transducer, based on a surface modified gold electrode, has the ability to monitor affinity based interactions directly, provided that the interactions introduce mea
Caloplaca arandensis, C. archeri, C. craggyensis, C. queenslandica and C. wallabyensis from Australia and Caloplaca subsaxicola from New Zealand are described as new to science and compared with allied taxa.
Fuel cells are promising for future energy systems, because they are energy efficient and able to use renewable fuels. A fully coupled computational fluid dynamics (CFD) approach based on the finite element method (with the software COMSOL Multiphysics) in two-dimensions is developed to describe an intermediate temperature solid oxide fuel cell (SOFC) single cell. Governing equations covering heat

This dissertation deals with the educational discourse of the military government in Argentina during the years 1976-1983. In March 1976, the army assumed power through a coup d´état. The intervention was carried out in the name of Order, i. e. to save the country from the crisis in which it was immersed. Through the Proceso de Reorganization Nacional they attempted to restore order and discipline
Popular Abstract in Swedish Dagens konsumenter översköljes ständigt av en aldrig sinande ström av budskap om vad man ska och inte ska äta för att leva hälsosamt. Detta bombardemang har ökat under de senaste årtiondena då diverse aktörer, så som representanter från hälso- och sjukvårdssektorn och statliga myndigheter, ytterligare har poängterat kopplingarna mellan individers matkonsumtion och derasConsumers today are constantly showered with a vast array of different messages about what and how they should and should not eat in order to lead a healthy life. This bombardment has escalated over the last decades as various actors, such as representatives from the medical community and public policy makers, have increasingly stressed the connections between individuals’ food consumption habits
Popular Abstract in Swedish Att förstå mekanismen som bestämmer djurs beteende är inte lätt. Genom att studera beteendet hos enklare djur kan man göra det mer förståeligt. Om man vill studera ljusstyrt beteende är det enklaste djuret att använda en manet från karibiska området vid namn Tripedalia cystophora. Denna manet har ögon som liknar människans ögon. De lever i vattnet i mangroveskogar och äMost animals use eyes to guide their behaviour. Analysing, and understanding, visually guided behaviours gets more complicated the more advanced the animal gets. Box jellyfish provide a relatively simple system for understanding visually guided behaviours. They have a limited nervous system, but they also possess a visual system that is quite impressive for a jellyfish. Box jellyfish have 24 eyes
