2. 1. Analysis of adhesively bonded joints : an asymptotic approach

   Author : Peter Schmidt; Anders Klarbring; Anders Boström; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive Joints; Asymptotic Expansion; Engineering mechanics; Teknisk mekanik;

   Abstract : Simulations using the Finite Element Method (FEM) play an increasingly important role in the design process of joints and fasteners in the aerospace industry. In order to utilize the potential of using adhesive bonding, there is an increasing need for effective and accurate computational methods. READ MORE

4. 2. Epidemiological Studies of Multiple Sclerosis in Sweden with focus on the County of Värmland

   Author : Inger Boström; Anne-Marie Landtblom; Trond Riise; Anders Svenningsson; Linköpings universitet; []
   Keywords : ;

   Abstract : The aim of this thesis was to study the frequency of MS in the suggested high-risk area of Värmland county by investigating the current prevalence and analyzing the development over time; secondly to investigate some aetiological factors – the pattern of industry, both in relation to MS in Värmland and in the whole country, and also to examine the possible relation between the distribution of MS and ALS, as it has previously shown a positive correlation in two studies; finally to analyze the women-to-men ratio of MS in Sweden because of international reports of an increasing ratio.Clinical data was collected from hospitals and other health care units in the county of Värmland, to calculate the prevalence ratio.

   Abstract : The overall aim of this thesis was to elucidate haw persona with muscular dystrophy (MD) and their next of kin experience and describe their daily lives over the last ten years. MD is a group of inherited disorders characterised by muscular weakness caused by muscle wasting. Both qualitative and quantitative methods were used. READ MORE

6. 4. Application of fuel design to mitigate ash-related problems during combustion of biomass

   Author : Anders Rebbling; Christoffer Boman; Dan Boström; Marcus Öhman; Nils Skoglund; Sonja Enestam; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermochemical energy conversion; biomass; combustion; ash chemistry; fuel design; ash transformation reactions; renewable energy;

   Abstract : The energy supply of today is, through the use of fossil energy carriers,contributing to increased net emissions of greenhouse gases. This hasseveral negative effects on our environment and our climate. In order toreduce the impact of this, and possibly to reverse some of the effects, allrenewable energy sources must be used.

   Abstract : The direct variable costs for heat and electricity production based on solid biomass fuel combustion is approximately 3-5 times lower than the costs in a fossil fuel-oil based boiler in Sweden. In addition waste derived biomass fuels are typically much cheaper than biomass not classified as waste. READ MORE
