Acid sulphate soils is a wide spread problem along the northern coast of Sweden. This is causing great damage through low pH and leaching of metals out into the streams. These soils are estimated to be found in several places in Sweden but also in many other areas in the world. One of these areas in Sweden that are believed to contain these sediments is Mälardalen. The purpose of this study is to evaluate the extension of the acid sulphate soils in this area.

For research purposes Saab has developed a generic mathematical model denoted VEGAS of an aircraft with a configuration similar to JAS 39 Gripen. Today parts of Gripen backup control system are used also for VEGAS making the system subject to both corporate and defense secrecy. The main objective of this master thesis is to design, verify and implement public pitch axis flight control system for VEGAS. Furthermore, simplifications regarding the design process is to be examined. Design of pitch axis flight control system for the entire flight envelope has been carried out.

 In today?s society teachers will face students of foreign origin. It is up to the teachers to help these students gain the knowledge they need to flourish in society. Despite the fact that mathematics is a universal topic with high status in many countries, studies have shown that mathematics is a subject where a large proportion of foreign students fails. The purpose of this study was to see wherein the problem lies and describe teachers' perceptions of the barriers and the opportunities in mathematics for students with Swedish as a second language.

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

The purpose of this study was to examine the narrative skill of sixyear-olds in terms of macrostructure and cohesion, and its relation tonarrative content, auditory attention, auditory short-term memory and threemeasures of word retrieval. A group comparison of macrostructure andcohesion was also performed between children with and without epilepsy.The material consisted of audio recordings of 44 children (18 with epilepsyand 26 from a reference group) retelling the story Nelli-sagan (Holmberg &Sahlén, 2000). No correlation was found between content and macrostructureor cohesion, but several between the latter two. Auditory short-termmemory and word retrieval without pictures showed several correlationswith macrostructure as well as cohesion. No differences in macrostructure orcohesion were found between the children with epilepsy and the referencegroup.

Milk fat is an important feature in many different milk products and other foodstuffs and it is often crucial for the dairy plants that the milk fat is stable for different manufacturing processes. Lipolysis is the enzymatic degradation of fat and is the one of the causes for an elevated amount of free fatty acids (FFA) in milk. Further, the change in fatty acid (FA) composition in milk can affect the stability of the product and also the manufacturing process. Both internal and external factors, at farm level or at the dairy plants can affect both FA composition and content of FFA. Milking frequency (MF=number of milkings per cow and day) and the composition of feed are two examples of factors generally performed at farm level. The objective of the present study was to evaluate how FA composition of milk and amount of FFA are influenced by two different ingredients supplemented to concentrate.

Today electronics becomes more and more complex and to keep low costs and power consumption, both digital and analog parts are implemented on the same chip. The degree of automization for the digital parts have increased fast and is high, but for the analog parts this has not come through. This have created a big gap between the degrees of automization for the two parts and makes the analog parts the bottleneck in electronics develop. Research is ongoing at Electronics systems group at Linköping University target the increase of design automization for analog circuits. An optimizationbased approach for device sizing is developed and for this a good optimization method is needed which can find good solutions and meet the specification parameters.

A webpage can be perfectly usable but if users are unable to find the webpage it will remain unused. Nine out of ten Swedes use a search engine and the most popular one is Google, amongst other search engines. In this report I seek to answer which ranking factors that should be included in an SEO-audit of an existing webpage and also how to optimize a webpage for search engines. Applying the method heuristic evaluation normally used to discover usability issues in an existing interface, on TT News Agency?s campaign site I found issues having a negative impact on the visibility in Search Engines Page Results.

This is a study about source criticism in Swedish health magazines in 2014 which is based on Torsten Thuréns positivist philosophy of science and formulations about source criticism. The thesis was based on the hypothesis that the Swedish health magazines are inadequate in their source-critical approach. To prove or disprove the hypothesis a quantitative content analysis of one hundred articles was made. The quantitative content analysis was based on twelve variables and the results showed that the hypothesis to some extent was true. The magazines reported their sources in most cases, but the majority of the sources consisted of various authorities such as doctors, psychologists, and personal trainers.

The aim is to find out how teachers apply the knowledge they get from mathematics pilots in preschool and from mathematics developer in the municipality, as well as how they work further towards the children with mathematics.The study is based on qualitative interviews with two teachers, one mathematic pilot and one mathematic developer. I used the semi-structured interview questions.The results show that teachers believe that mathematics pilots will inspire the teachers in their work with mathematics in preschool. One of the teachers who were interviewed said:?Mathematics pilots should be those that have the strongest glasses and coming up with new ideas and they push the rest of the teachers in their work with mathematics in relation to children in preschool?.The teachers use the correct terms for mathematical concepts with the children. They also stressed how important it is to point out to the kids that it is mathematics that they are doing.The conclusion of the study is that the teachers agree that it is their approach towards the children that is important and how they can lead the children?s interest of mathematics forward.

EPiServer is a content management system where users can publish information on a website by using a web browser. EPiServer has a built-in search engine that is very simple. Many customers using EPiServer web publishing system is in need of more functionality than is offered by EPiServer's built-in search engine. The purpose of this thesis is to develop additional functionality extends that the built-in search engine in EPiServer. The assignment was also to identify what need to be developed in order to give customers a better  opportunity to help their visitors find the right information on their website.Since this thesis was started in 2005, a number of commercial search engine productsentered  the market and it has become more common for companies to invest inthese products instead of using the simple search engine that's built into EPiServer.These products have many of the features that have been developed in this thesis.Another crucial difference between EPiServer?s built in engine and other products isthe method used to index content.

This study examines the in-game encyclopaedia Codex as it appears within the videogame Mass Effect. The purpose of this study is to analyse the Codex with emphasis on how the reading process is affected by the videogame medium. In this regard the study seeks to uncover what characterises the Codex as a fictional encyclopaedia, what it entails and how it interacts with the rest of the game. The theoretical basis of this study is derived from a combination of the writings of Wolfgang Iser concerning the process of reading, Jesper Juul's writings on the relationship between games and narratives, and the concept of intermediality as discussed by Hans Lund and Jørgen Bruhn.      This study is based on a close examination of the PC and Playstation 3 versions of the videogame Mass Effect, created by Bioware, with particular emphasis placed on the Codex. Mass Effect is a science fiction third-person shooter and RPG set in a future where mankind has begun interacting with aliens civilizations and colonising new planets.
