Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

The construction of buildings and paved surfaces changes the natural water balance.Precipitation generates surface runoff and storm water instead of infiltrating into the soil.Storm water has come to be considered as a major source of pollution in lakes and streams inthe vicinity of urban areas. Reduction of pollutants in storm water is a key action in order toprotect sensitive recipients and maintain high water quality. Storm water is traditionallytransported by storm sewers to the nearest recipient. In recent years the approach to stormwater management has changed; storm water should primarily be disposed of on site, throughlocal disposal of storm water, LOD. LOD is created by a combination of the function ofseveral smaller local facilities and the general sewer system.

Syftet med vår studie är att undersöka hur människor där den kreativa processen är central i sitt yrkesutövande upplever denna process och se om det går att hitta ett mönster. Vi bestämde oss för att ta reda på vad som händer inuti människan runt det kreativa ögonblicket. Vår huvudfrågeställning är: Vad är den kreativa processen? Vi gjorde öppna intervjuer med fem verksamma kreatörer med hjälp av DV-kamera. Vårt resultat visade att det gick att se ett gemensamt mönster i den kreativa processen.

Two different methods for measuring biogas production were used, gas meter and gasbags. The gas meters were electronic and counted each time a certain gasvolume passed through them. The gasbags collected the gas that hade passed through the gas meter until a manual measuring could be done. The two different methods gave the same result for a volume at three liters but for a volume around 0,2 liters they did not. Accuracy and precision for the gasbags was more exact than for the gas meters even if the method was difficult with a lot of different elements that could affect the result.

One of the main tasks of the Swedish Armed Forces over the past few years has been International assignments, which increased the importance of the Lessons Learned process. Methods of simulator training with computers have become more frequent and the technical ability to collect digital data from sensors has been developed as well. This work demonstrates how the experience of Lessons Learned can be communicated with the computer simulator StriSimPC and how modern technology in future support experiences from the Lessons Learned process at the tactical level in the Army.Currently knowledge sharing consists of several processes and strategies in the Swedish Armed Forces. This is done by written reports, oral presentations and different practical exercises.This case study shows the functions of the simulator StriSimPC, methods of training and how it is used today. The study also describes the future opportunities, where digital metadata acquired from the modern combat vehicles could contribute sharing of experience in the Lessons Learned process.The summarized conclusions indicate that StriSimPC can combine the two strategies for personalization and codification of knowledge transfer to reach a higher level of learning.

This thesis is a qualitative study in which 12 award-winning printed adverts, awarded with either a Swedish ?Guldägg? or an international Clio Award, have been analyzed from a rhetorical perspective. Visual rhetorics were used to analyze the adverts in order to expose the rhetorical concepts and to find out whether the rhetorical concepts represented in the Swedish adverts are the same concepts represented in the international adverts. One of the conclusions drawn is that pathos-arguments, a rhetorical concept where the senders allude to the emotions of the receivers, are the most prominent in both Swedish and international adverts, but are used in different ways. Another conclusion drawn is that the adverts are overall characterized by their messages not being explicit.

Stump biomass is energy rich and stump harvesting for use as fuel become more and more interesting in Sweden. Swedish Forest Agency (2009) has estimated that stump harvesting in Sweden would respond to an annual energy supply of 57 TWh/year. However, stump has not been recognized as a bioenergy resource in Sweden. Suitable methods for pre-treatment of stump are probably of great importance to make it accepted as fuel. It is therefore rewarding to carry out an investigation in this area for stump. This report represents results from a diploma project, which was aimed to develop a fixed bed reactor for experimental study of biomass torrefaction, followed by TG analysis and kinetic modelling employing Ozawa method and different kinetic models including one-step and three-pseudo-component models.

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

The main objective of this thesis is to study how the structures of a sell dialog, via a web shop, should be designed in order to support and inspire the customer. To get the answer to this question I use a qualitative and quantitative method. The qualitative method is applied in connection with different interviews. The quantitative method is used to analyze different answers given from those who are interviewed. I also use the deductive method due to my interest of studying how reality can relate to the theories with the choice of the subject.Moreover, this thesis is structured by three main perspectives; company, customers and techniques.

This is a qualitative study of how some journalists on the Swedish national media are using social media in news work. The study, carried out by using interviews, also covers how these journalists' work is influenced by social media. For the journalists in the study social media has become a tool to do research, get news ideas and find interviewees. At the same time social media affects the work of the journalists, as the social media increases the speed of news and flow of information. Even though they involve some challenges, social media facilitates news work and the journalists in this study have a positive attitude towards the phenomenon.Keywords: Social media, news journalism, the national media..

Climate changing is a growing problem for many countries and communities over the world. The cities has a huge work to deal with in their reforcements of their cities to be resilient ones. This thesis makes an effort to investigate and illuminate some of the problem the cities has to solve related to flooding, hazards, erosions, rising sea levels and crotches. This thesis will help to find solutions that international and national efforts has produced and handed out to each other. A lot of communities are charing their excellent tools that works for them.

The purpose of this thesis is to analyse studies that evaluate Web search engines. This is done in four categories; the researchers? purpose, the evaluation measurements, the relevance, and the time aspect. Our method is based on a text analysis in which we use the direction of analysis of the content of sixteen evaluation experiments. Our results indicate fundamental differences in the way the researchers are tackling the problem of evaluation of Web search engines.

The market offers more and more products that are claimed to have medicallypositive effects (like increased blood perfusion etc.) due to their magneticproperties. The objective of this study was to investigate if blankets containingpermanent (static) magnets have a greater impact on cutaneous blood circulationthan ordinary blankets without magnets. Eight standard bred horses were used in across-over study. The cutaneous temperature was presumed to reflect blood flowin the skin and therefore thermography and local thermistors were used to indicatechanges in circulation. Baseline values were registered before the blanket wasapplied.
