Multikanalsljud, surround, har ökat i popularitet de senaste åren och har gått från att vara en upplevelse som endast kunde fås på biograf till något som finns i många människors vardagsrum. Formatets styrka är att den upplevda rumsupplevelsen ökar samt att olika ljudkällor kan få större och bättre separation. Då man sammankopplar det visuella intrycket av en persons position med det ljudande får lyssnaren lättare att separera olika ljudkällor. Upplevelsen blir därmed mer lik den situation som uppträder i verkligheten. I detta arbete ville vi hitta en praktisk lösning som möjliggör att surroundljud också kan erhållas ur livesituationer, t.ex.

Water hardness indicates the concentration of calcium and magnesium ions in water. Water with high concentrations of these ions is described as hard water and water with low concentrations is described as soft water. Water that is too hard or too soft can lead to technical and economical problems. In collaboration with Midvatten AB, groundwater hardness in the Badelunda esker between Leksand and Avesta has been mapped, and an attempt has been made to explain the variations. For this purpose, different GIS programs, such as ArcView, ArcInfo, IDIRISI, and one geochemical modelling program, PHREEQC, has been used.

Arbetet beskriver en analys av innehållet av membranbundna och periplasmiska c-cytokromer hos perkloratodlade GR-1 och jämförelser med c-cytokrominnehållet hos Ideonella dechloratans och andra kända c-cytokromer, samt med genomet för Dechloromonas aromatica. Den jämförande studien av c-cytokromer gjordes med syftet att undersöka en hypotes om att bakterierna använder olika vägar för elektronöverföring till det periplasmiska enzymet (per)kloratreduktas. Cellmembran från GR-1 renframställdes genom ultracentrifugering och periplasma preparerades fram med hjälp av osmotisk chock. Fraktionerna analyserades sedan med SDS-PAGE och peptider med kovalent bundet hem (c-cytokromer) detekterades med hjälp av en specifik färgreaktion. Även Touchdown PCR med degenererade primrar genomfördes på isolerat DNA från GR-1 i ett försök att finna en gen kodande för ett NapC/NirT-liknande protein.

Akademiska Hus owns and manages the university facilities in most university towns in Sweden. Bilbergska house in Örebro was built in 2008 by Akademiska Hus, and designed by White Architects. Today's buildings must meet accessibility requirements determined by Swedish Board of Housing, and it is the developer who must ensure that they are fulfilled. Swedish Board of Housing requirements are often vaguely written and interpretation space is large.This report aims to investigate how much of the requirements which are set towards the University and landlord Akademiska Hus are being achieved. This is done by studying the requirements that are set.

I was assigned to the thesis as part of a project GMA AB (Ground Machinery Applications AB) is running. The project aims to develop a new method for injection of drilled holes in rock walls. Currently, the injections usually involve cement but the basic idea of the project is to replace cement with a supplement called Silica sol.Silica sol is known as a gelling liquid. The gel time is controlled by a mixing of saline. Depending on the amount saline that gets mixed in, the gel time varies.

This study focuses on romantic friendship between women in three Swedish novels written between 1836 and 1857: Sophie von Knorring?s (1797?1848) Illusionerna (1836), Fredrika Bremer?s (1801?1865) En dagbok (1843) and Marie Sophie Schwartz? (1819?1894) En fåfäng mans hustru (1857). Also, the connection between women and passion as well as the interesting occurrence of step- and foster mothers is looked upon in the study.The romantic friendship is freely expressed in these novels; love between women is neither presented as unnatural or unchaste. It both challenges the heterosexual matrix? claim on intelligibility and its rules for how desire should be expressed.

Discharge of untreated wastewater leads to unnaturally high levels of nitrogen and phosphorus in rivers, lakes and the sea, which results in unbalanced ecosystems with eutrophication and lack of oxygen. Part of the phosphorus in surface waters is coming from on-site wastewater treatment from scattered households with unsatisfactory purification. Blast furnace slag is a by-product from iron production, and has in laboratory trials showed good phosphorus binding capacity. To test blast furnace slag as a reactive filter media for phosphorus separation in a full scale experiment, a wastewater treatment plant has been built behind the picnic area at Ångersjön alongside the road E4 in central-eastern Sweden. The plant contains two parallel lines, one with blast furnaces slag and the other with Filtralite-P as phosphorus sorbent. Both filters have showed decreasing phosphorus purification effect with time in spite of a low wastewater load.

The strategy when you change the visual part of the brand identity is often referred to as Corporate rebranding and is seen as a good way to show that a company has undergone a change. Despite high risks and high costs, this strategy has become more common and there are companies today who make the choice to change an already well-known graphic profile. This phenomenon is what underlies this essay?s problem statement: Why does a company with an already well-known graphic profile choose to change it and how does the process behind the change occur? In what way have the company?s customers recognized the change and how has the company?s image changed in this context? The purpose of this essay is therefore to explore the process that occurs when a company in the sport and fashion industry changes its visual identity and to explore how the company?s customers have perceived the change.To fulfil the purpose of the essay a case study was carried out on a company?s Corporate rebranding process. The company that was chosen was the Swedish sports retail chain Stadium Sweden AB who decided to change its graphic profile even though their logo was one of the two most recognized in their field.

The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

This report covers the conceptual design of a new one person hybrid vehicle that is to be fast and convenient to drive on the roads. The vehicle is most of all supposed to be used as a commute vehicle but can also be used at other occasions as well.During the work with this project the group has focused on three larger areas, the outer design (body), wheel chassis and an ergonomically designed interior. The group was not able to just create these parts in 3D to get a trustworthy vehicle, hence number of other components and details were also created to get a better entirety.The outer design starts with idea generation and sketches and ends with a 3D model which is rendered to show how the final product is going to look. The design of the body has been going on during the entire work process due to new ideas and improvements that seemed interesting and had to be changed.The wheel chassis also started with idea generation, research and sketches. It ended up with a simulated 3D model which later on was mounted on the vehicle body to show how the vehicle is going to perform during usage.

AbstraktHaving influence over questions that concern us is a part of the society that we live in, where every individual have the right to make her voice heard (Danell, 2006). For many decades, the school has had many different ways to give the students influence. Rönnlund (2013) is giving a historical overview of the history of students influence and enlighten us how the influence has changed over time. The influence from the students is very important and it is the students right to make their voices heard about things that concerns their work environment but also to affect their curriculum. The education in school should be fitted to every individual student (Danell, 2006).   According to Aaron Antonovsky (2007) our wellbeing is based on that we all can take part and deicide about the things we are meant to do.

Haemonchus contortus is the most important bloodsucking gastrointestinal nematode in small ruminants worldwide. It is often controlled by anthelmintics. Even though other methods to control are available, the most efficient way to treat an animal with clinically manifested haemonchosis is to use one of the available broad spectrum anthelmintics: benzimidazoles (BZ), macrocyclic lactones (ML) or imidothiazoles-tetrahydropyromidines or the narrow spectrum drugs salisylanilides or nitrophenols. Anthelmintic resistance (AR) against all groups of anthelmintics in nematode parasites has been reported from many countries, and even multiple AR has been observed. In this study I have investigated the resistance levels to all major classes of broad spectrum anthelmintics in a naturally infected flock of sheep of Red Maasai sheep (RM), Dorper sheep (D) and their offsprings on a research farm in Kenya.

The aim of this study was to explore and gain understanding of the situation between managers in different forms of human service organizations. I chose to use a qualitative method and conducted semi-structured interviews with five professional middle managers in the public sector. To accomplish my purpose, I worked on the basis of several questions. The questions dealt with the role of middle management and what it involves, how it is perceived and what the middle managers think of the specific requirements for them and their leadership in organizations that provide services relating to people.  As a result of the analysis I have used the theory of social roles that describes the meaning of the different roles and role conflicts that arise in connection with various and conflicting expectations. The review of the results shows that middle managers in human service organizations experience to have to deal with a complex leadership role.
