The demand for district heating is expected to decrease in the future, due to competition from heat pumps and energy efficiency measures in buildings. Development of existing district heating systems is therefore necessary for district heating companies to maintain market shares. This Master?s thesis describes and investigates the heat and electricity production and profitability of a combined Organic Rankine Cycle (ORC) and heat pump that is integrated with an existing district heating system. The studied district heating system is utilizing heat from waste incineration. In Sweden waste constitute 20 % of the fuel mix used in district heating systems, and this share is expected to increase in the future.

AbstractAn approaching overproduction of cereals and a future uncertain supply of non genetic modified vegetable protein feedstuffs have increased the interest in an expansion of the domestic production of protein feedstuffs in Norway. Besides rapeseed (Brassica campestris), peas (Pisum sativum) may be the most suitable crop for this purpose. Peas are characterized by having a relatively high content of crude protein, ranging between 20-26%, a high content of starch, 42-51%, and a low content of fat. In general, the energy value for peas is higher than for barley but lower than for rapeseed and soybean meal.Pea protein consists of albumins and globulins to 85-100%, which leads to the fact that a large part of the pea protein is soluble and degradable in the rumen. Starch in peas is on the other hand to a large extent resistant to rumen degradation compared to starch from other starch rich feedstuffs.

A foundation of our welfare state is that we have a social safety net. This safety net is designed to pick up individuals who are in need of help and support to manage their way of life. This essay regards people who need help with care or people who need help with an addiction. This essay is a qualitative text analysis, which aims to see whether, and if so how, help-seekers are constructed in 40 social service documents within a municipality in central Sweden. We have endeavored to illustrate the power that the written word possesses and which categories of people are constructed depending on the language and content of the social documents.

The purpose of this BA-thesis was to learn the differences in news broadcasts between one public service radio channel and two commercial radio channels. To do this we used a quantitative analysis method to examine the content of the news broadcasts and then we conducted in-depth interviews with several people working with the different radio channels using a qualitative research interview method to learn their views on news and news broadcasting.We measured the differences between the channels in six areas: subject, headline, news presentation, gender, advertising and sources.Our two main theories were normative theory and media logic.The results found that there were several major differences between the public service radio channel and the two commercial radio channels. Apart from several important differences in the six measured categories we also found that the sound and tone in the public service radio channel was very different from the two commercial radio channels.We also found the public service radio channels news broadcasts to be more serious than the two commercials ones?..

The main aim in this Master thesis is to analyse how an ideological view may have influenced the shape of hierarchies with a specific concentration on the concept of fiction genre in the latest versions of the systems SAB and DDC. Our thesis is that no theoretical classification scheme can be recognized as objective. With an ideological/institutional perspective we look at the structures behind these systems. As a vehicle we use the hermeneutic circle to show the play between part and unit by focusing and analysing three different levels: the content level the concept level the ideological level. The first level is in the shape of a historical background and an analysis of concept with focus on content.

Before the autumn term 2011 the Swedish compulsory school adopted new syllabuses in relation to, inter alia, religion. Changes within the religion topic have historically been a heavily debated issue among decision-makers, interest groups and the church, where the role of the Christianity has been particularly controversial.The main purpose of this study is therefore to investigate how the Swedish compulsory school?s teaching of Christianity has changed over the years. I have in order to conduct this study applied a descriptive method as well as a content analysis. The Swedish compulsory school?s current and historical syllabuses in religion have served as basis for this study.The outcome of this study clearly shows that the Christianity has received less influence to the benefit of other topics.

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.

AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power.  ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant.  As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol.  Etanolens framtid vilar på bra lösningar för framställning.  I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle.  Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.

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.

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.

This report is the result of a thesis work carried out on the Risifrutti production at the company Procordia Food AB. The thesis is at a master level and is the final work for the author to receive a Master of Science in Innovative production at Mälardalen University. The thesis comprises 30 credits and has lasted for 18 weeks. The thesis is mainly a research on whether it is possible to perform an Environmental Value Stream Map (E-VSM) in a food processing industry and an evaluation if the tools E-VSM and Green Performance Map (GPM) are useful in this type of industry. An extra part to this research is to use the results from the E-VSM and give Procordia Food AB information on improvement potentials in the Risifrutti production. The author has found it difficult to collect some of the quantitative data to the E-VSM, mainly regarding energy, but by using the Value Stream Mapping (VSM) tool and other Lean tools the author was able to identify and quantify several wastes in the Risifrutti production. Recommendations for improvements based on these wastes have been given to the company. In the research part of this report the utility of the Value Stream Map, Environmental Value Stream Map and Green Performance Map in a food processing industry have been analyzed. The author has found that the Value Stream Map has been a useful tool since waste and unevenness in the tact of the production has been identified. The Environmental Value Stream Map and the Green Performance Map are also great tools when a company wants to analyze their environmental impact and then invest in environmental improvements. However, no profound energy analyzes has been done in the Risifrutti production because of the lack of energy meters for steam, electricity and compressed air in the production lines..

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.
