Background: Hydroxyethyl starches have been withdrawn from the European market. In Sweden, dextran was the main colloid until 2000, when starches overtook the market. After the recent 6S-trial, it was suggested that dextran could be reinstituted, but concerns for greater coagulopathy, bleeding and anaphylaxis still remain. An experimental study from our department indicated that isovolemic substi
The pulp and paper industry is one of the most important industrial sectors worldwide. The focus of current pulp mills is on the production of cellulose pulp fibres and electricity. By converting traditional pulp mills into biorefineries they can be a keystone in a future bioeconomy based on renewable resources instead of fossil fuels. In order to achieve this, pulp mills have to close their loops
In the context of an international trend of claims for historical justice, several aspects of Swedish contemporary history were re-evaluated in the 1990s. One of the most well-known examples is the heated political and scholarly debate on involuntary sexual sterilization, sparked by a series of critical newspaper articles in August 1997 that attracted international media attention and resulted in
The level structure of 102Pd has been investigated using data collected with the Eurogam 2 array. Several cascades of γ-rays have been established up to high spins. Termination of rotational bands has been observed at Iπ = 28 - and 32 +, and tentatively at Iπ = 38+ and 42+. The nucleus 102Pd is the first case where rotational bands built on valence space configurations are followed from spin close
Central Africa has the lowest food production per capita, slow yield development and the fastest growing population in the world. This study aimed to develop a model, which estimates the grain surplus or deficit in Cameroon for 2015-2030. Grains form the main diet in Cameroon and the modelled grains in this project are sorghum, millet, rice and maize. Additionally, in the case of a deficit, the yi
An ever-increasing proportion of young males treated for cancer are cured. Therefore, one of the major challenges of modern Clinical Oncology is to ensure good quality of life. Cancer disease per se as well as cancer treatment may have a negative impact on androgen production, thereby leading to subclinical or clinically overt hypogonadism. Since the symptoms of androgen deficiency are rather unsp
THESE EXERCISES SERVE THE PURPOSE OF TRAINING THE UNDERSTANDING OF SEVERAL BASIC CONCEPTS IN ELEMENTARY UNIVERSITY-LEVEL MECHANICS. WHEREAS MECHANICS IS OFTEN TAUGHT AS A COURSE WHERE “PEN AND PAPER” ARE THE ONLY TOOLS, THESE EXERCISES ATTEMPT TO PROVIDE KNOWLEDGE ON HOW THE BASIC THEORY WORKS, ON PRACTICAL PROBLEMS, BY USING A MODERN SIMULATION COMPUTER SOFTWARE. BY SIMULATIONS THE GENERAL PERFOR
Popular Abstract in Swedish En stor del, kanske den största delen, av den information som vi dagligen får om världen tillhandahålls genom ett av våra fem sinnen: synen, med vilken ögat registrerar det ljus som vi omges av. Det ljus som vi kan registrera och uppfatta som färger är egentligen bara en bråkdel av den elektromagnetiska strålning som universum är uppfyllt av: Det finns även röntgenstrålThis thesis intends to provide spectroscopic information which may be of use in the investigation of low-density plasmas. Developed since the 19th century, the spectroscopic approach has proven to be a versatile method for measuring properties in hot gases, such as electron and ion temperatures and densities, the abundance of various elements in the gas, etc. However, such investigations rely on k
We explore whether off-the-shelf accounting solutions are used or not used in management control. This study explores the usage of accounting solutions such as ERP, “hybrid ERP”, and “best-ofbreed” (BoB). Previous research highlights the problem that ERP has a “moderate” impact on management control but no study addresses whether hybrid ERP and BoB adopters experience the same problem. The explora
Nocturnal vision is a demanding task for insects with small eyes. As it gets dimmer the noise imposed by the stochastic nature of photon arrival makes vision unreliable. Despite this, there are quite a number of animal species that are active at night and apparently see well. In this thesis I show that the compound eyes of nocturnal insects are sufficiently flexible to adapt to the particular wind
Consumers are pushing for higher data rates to support more services that are introduced in mobile applications. As an example, a few years ago video-on-demand was only accessed through landlines, but today wireless devices are frequently used to stream video. To support this, more flexible network solutions have merged in 4G, introducing new technical problems to the mobile terminal. New techniqu
This paper introduces a general logical framework for reasoning about diffusion processes within social networks. The new “Logic for Diffusion in Social Networks” is a dynamic extension of standard hybrid logic, allowing to model complex phenomena involving several properties of agents. We provide a complete axiomatization and a terminating and complete tableau system for this logic and show how t
Background and purpose In Sweden, surgery for knee osteoarthritis (OA) in patients younger than 55 years of age has doubled during the last 10 years. We evaluated the use of 3 surgical alternatives: high tibial osteotomy (HTO), unicompartmental arthroplasty (UKA), and total knee arthroplasty (TKA). We also examined the outcome, expressed by rate of revision. Methods The numbers of all procedures d
In this paper a constitutive model for glassy polymers is developed. Glassy polymers consist of a number of polymer chains that at a microscopic level form a network. If the distribution of the polymer chains shows some preferred direction, the mechanical response at a global macroscopic level will be anisotropic. To incorporate the orientational distribution of the polymer chains, a homogenizatio
The aim was to study the metabolic pathway for N-methyl-2-pyrrolidone (NMP) in humans. Three healthy male volunteers were administered 100 mg NMP orally. All urine was collected during nine consecutive days. The identification and quantification of the metabolites were performed by gas chromatography/mass spectrometry (GC/MS). NMP, 5-hydroxy-N-methyl-2-pyrrolidone (5-HNMP), N-methylsuccinimide (MS
