Background Despite high incidence of ankle fractures in the elderly, studies evaluating outcome and impact of quality of life in this age group specifically are sparse. The aim of this study was to evaluate outcome and quality of life 6 and 12 months after injury in patients 65 years or older who had been operated on due to an ankle fracture. Methods Sixty patients 65 years or older were invited

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

This paper argues in line with recent work by Pesetsky and Torrego that given the operation Agree there is no need for the concept Abstract Case in Narrow Syntax. Morphological case exists in many languages, and is here, following a suggestion by Halldór Sigurðsson, seen as the result of an instruction to PF how to translate syntactic structure into morphology. I will call this instruction CAM, sh

During the process of migration, many immigrants undergo a number of changes in their relationships to their religious organisations. One factor that has emerged as especially important in immigrants’ congregational affiliation is the availability of language groups in immigrants’ mother tongues. This article examines how these groups are formed and the roles they play in the lives of their member

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

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

In the first essay of this thesis we develop a model for calculating the net expected value of a swap agreement subject to dual-default risk. The main explanatory variable for the net expected return of a swap is the default intensity of each party measured by the credit rating of the firm. We derive the net expected return of the swap as a function of the credit rating of the firm receiving the f

Ecosystems along the 0degreesC mean annual isotherm are arguably among the most sensitive to changing climate and mires in these regions emit significant amounts of the important greenhouse gas methane (CH4) to the atmosphere. These CH4 emissions are intimately related to temperature and hydrology, and alterations in permafrost coverage, which affect both of those, could have dramatic impacts on t
