Mechanism-as-activity and the threat of polygenic effects

Polygenic effects have more than one cause. They testify to the fact that several causal contributors are sometimes simultaneously involved in causation. The importance of polygenic causation was noticed early on by Mill (1893). It has since been shown to be a problem for causal-law approaches to causation and accounts of causation cast in terms of capacities. However, polygenic causation needs to

A comparison of a plane 2D finite element and a 2D axisymmetric finite element used for the heat or diffusion problem

As a pre study for future work the output from a regular plane solid 2-dimensional finite element was compared with the output from a solid 2-dimensional axisymmetric finite element. It was done by creating a very simple finite element model for the heat convection problem. The purpose was to compare the results from a heat convection analysis. The model can be used directly for the mass diffusion

Quantitative analysis of circadian variation in atrial fibrillation frequency

Circadian variation in atrial fibrillation (AF) frequency is explored in this paper by employing recent advances in signal processing. Once the AF frequency has been estimated and tracked by a hidden Markov model approach, the resulting trend is analyzed for the purpose of detecting and characterizing the presence of circadian variation. With cosinor analysis, the results show that the shortterm v

Religious Stereotyping and Interreligious Relations

Religion can heal, but it can hurt as well. This collection of essays addresses some key issues of religious stereotyping, prejudice, and discrimination, and considers a wide range of important topics which haunt our societies today. When stereotyping becomes the oxygen we inhale, when it is so important to us that we cannot see how we can survive without it - what can and should we do? Twenty-two

Personsäkerhet i tunnlar - Inventering

Banverket äger och förvaltar ett stort antal tunnlar samtidigt som planering och byggande pågår för ett flertal tunnlar. Syftet med föreliggande arbete är att öka kunskapen och på sikt förbättra och förenkla processen angående personsäkerhet i tunnlar. Rapporten beskriver det inventeringsarbete som utförts med avseende på både befintliga och nya tunnlar med fokus på personsäkerhet...

Lidforss liv i AF-borgen

Genomgång av de tre arenor på vilka Bengt Lidforss agerade inom Akademiska Föreningen (AF): en privat (hans bostad i ett av AF:s studentrum), en offentlig (hans verksamhet som debattör och talare vid AF:s publika tillställningar) och en semioffentlig (umgänget inom det s k Tuakotteriet).

The Role of Carbon-Nitrogen Interactions for Terrestrial Ecosystem Dynamics under Global Change - a modelling perspective

Popular Abstract in Swedish Framtida klimatförändringar påverkas till stor del på människans utsläpp av CO2, samt av klimat- och CO2-relaterade återkopplingar genom kolcykeln i både landbaserade ekosystem och hav. Landbaserade ekosystem tar för tillfället upp omkring 25% av de antropogena utsläppen av CO2 från förbränning av fossila bränslen och markanvändning, men att tillskriva vilka mekanismer The nature of future climate change will depend on anthropogenic emissions of CO2, as well as climate- and CO2-mediated feedbacks through carbon (C) cycling in both terrestrial ecosystems and oceans. Terrestrial ecosystems remove presently about 25% of the anthropogenic CO2 fossil-fuel and land-use change emissions, but to attribute which mechanisms cause this uptake, and the key regions where it
