A promising technique for dating paleosols is reported based on radiocarbon (C-14) dating of asexual spores from vesicular-arbuscular mycorrizae (VAM). The soils are dispersed in water and some 6000-8000 spores separated by hand picking under a low power microscope. The dried spores are then dated by accelerator mass spectroscopy (AMS). A chronosequense of closely superimposed paleosols from an ar

Minimizing the use of energy is a central task in sustainable building. Minimizing the use of natural resources and maximizing the recycling potential are other important tasks to take into consideration. In low-energy buildings, the embodied energy accounts for a considerable part of the total energy use of the building. Therefore, it is also imperative to pay attention to the choice of building

Circadian rhythms are ubiquitous in biological systems and regulate metabolic processes throughout the body. Misalliance of these circadian rhythms and the systems they regulate has a profound impact on hormone levels and increases risk of developing metabolic diseases. Melatonin, a hormone secreted by the pineal gland, is one of the major signaling molecules used by the master circadian oscillato

Biomass gasification for energy or hydrogen production is a field in continuous evolution, due to the fact that biomass is a renewable and CO2 neutral source. The ability to produce biomass-derived vehicle fuel on a large scale will help to reduce greenhouse gas and pollution, increase the security of European energy supplies, and enhance the use of renewable energy. The Varnamo, Biomass Gassifica

Abstract in French Cet article pose la question de savoir s’il existe une corrélation entre le niveau grammatical et le niveau lexical dans la production écrite d’apprenants de français langue étrangère. Nous avons appliqué un certain nombre d’indices quantitatifs et lexicaux et un indice grammatical à 40 textes en français, écrits par deux groupes d’apprenants adultes suédophones se situant à des

Restyling Factual TV is about understanding genres in relation to each other and in relation to popular audiences. It takes as a starting point the idea that factual television is being restyled, that various kinds of news, current affairs, documentary and popular factual genres are part of a turbulent time in broadcasting. The boundaries between fact and fiction have been pushed to the limits in

To listen to the other: This phrase raises an incalculable number of issues. One of the central topics in teaching improvisation is learning how to listen to those with whom one plays, but in my experience the most difficult task is listening to the self. The point of listening to the other in performance is obviously not to completely give up the self, nor is it to become the other, but to attune

The combination of solar heat and ground-source heat pumps in dwellings gives opportunities for optimising the use of renewable energy sources and minimize the share of bought energy. Solar collectors in the system may give advantages for the operational conditions both for the solar collectors and for the heat pump. The aim of this project was to analyse different variables such as energy demand,
