Transient driftförhållande blir allt mer intressant för forskare och tillverkare och de största svårigheterna är att minska emissionerna utan att påverka bränsleförbrukningen eller motorns respons vid gaspådrag negativt. Huvudmålet med det här examensarbetet var utvärdera olika metoder för att mäta NOx och antal partiklar med hög tidsupplösning för att möjliggöra studier av emissioner under transient driftförhållande.I arbetet har en Horiba MEXA 120NOx NOx-sensor studerats med avseende på linearitet, mätsäkerhet och responstid. Försök för att öka noggrannheten har också gjorts genom att kompensera för varierande skalfaktor för utsignalen och för responstiden.Ett spädsytem har arbetats fram för att ge hög tidsupplösning och god repeterbarhet. I detta ingick en Rotating Disc spädare och en två-stegs Dekati spädare. Spädsystemet var kopplat till en TSI Ultrafine Condensation Particle Counter 3025 A (CPC) och var nödvändigt för att hålla koncentrationen inom det mätbara området.

This report will outline a proposal for the improvement of the baggage sorting facility at Arlanda airport. Swedavia is a state owned company group that operates, owns and develops airports in Sweden. One of their main roles is to create accessibility needed to facilitate and streamline the work at the airport.Swedavia is constantly working to develop new solutions and enhancements that will help to standardize and automate the work at airports without major impact on climate and above all adapt these solutions to work.The project has been aimed to identify and isolate the problem at the check-in counter, investigate the possibility of setting a speed control on the DC motor driving the luggage conveyer belt at the check-in desk so that the luggage does not lose tracking already there, as well as evaluate the new sorting systems planned to be introduce in the upcoming refurbishment of the sorting area.To determine the parameters that are used to regulate the speed of the baggage conveyor belt, information about the inputs and outputs that participated in the process was gathered. Information was collected both practically and theoretically. Process was followed and monitored by the supervisor of the company, and a theoretical study was done separately on my own.

Municipal Real Estate Companies runs by a political boarder who makes decisions in large investments. In some cases the municipal counter have to take the decisions about big and expensive investments. A successful investment needs to be built on solid ground.Media has lately focused on energy topics as a part of the environmental discussion and the real estate companies tries to use the new technology that the market has provided. Energy investments in new buildings are not longer a small part of the energy saving program. Long-term investment demands needs large knowledge and awareness about the energy topics that have recently grown in the municipal real estate companies.

Since the 9/11-attacks several nations have been confronted with a new international threat, its nature traces back to the political- and religious- radical movements of the 20th century Cold War. Ever since, various states have been under threat by terrorist organizations around the world due to mainly participating in worldwide counter-terrorist interventions created by western alliances. In Sweden, amongst other countries, the state took security-precautions that would imply total control of information throughout the territorial borders. The assigned proposition was accepted by the Swedish parliament in June 18th 2008, after this date wild spread criticism was still in effect ever since the Swedish government first publicly announced the proposition in May 8th 2007. This study emphasizes on understanding why the Swedish government chose to present this proposition to parliament, in order to complete this task the study will present the motives and the alleged threats that were the core of the proposition and its value-maximizing goal of creating a new surface for Swedish homeland security.

This thesis will deal with the development of the situation of the Roma minority in the Swedish school system in the period between 1954 to 2010, based on two Swedish Government Official Reports of the group's situation in the Swedish schools. The study is done by the report Zigenarfrågan (SOU 1956:43) and with the report Romers rätt (SOU 2010:55). The report Romers rätt was written by the Delegation for Roma issues and gives an updated picture of the situation of Roma in the Swedish school system. The state investigation Zigenarfrågan, is also important as the latter resulted in the Roma children enrolled in Swedish schools. This work will look at the various governmental investigations by the theory used for analysis called ?structural discrimination theory?.

The aim of the present paper was to see why a recommended course of action is not always followed in the way it is supposed to. The paper deals with a new method (SFA-metoden) used by The Social Insurance Agency in working with sick-listed people. Aspects that are elaborated on are local effects of the method at its introduction, case managers work conditions, and control of the implementation of the method. Two different methods of investigation have been employed. On the one hand, previous reports on the method have been analysed, and, on the other hand, two focus groups interviews, one consisting of case managers´ working with the method, and one constituted by their supervisors have been carried out.The results have been analysed in accordance with, on the one hand, the theory of street level bureaucrats and, on the other hand, certain concepts applied in the new institutionalism.

Syfte och frågeställning: Syftet med denna studie är att undersöka de eventuella fördelar styrketräning med yttre belastning kan ge kvinnliga truppgymnaster på juniornivå. Frågeställningar: Vilken effekt på explosivitet i nedre extremitet har sex veckors powerträning med yttre belastning på truppgymnaster? Skiljer resultaten sig från de som uppnås vid traditionell gymnastisk styrketräning?Metod: Två lag som representerar Sverige-eliten på damsidan i juniorklassen delades in i test- (n=7) och kontrollgrupp (n=8). Testgruppen genomförde under sex veckor ett specialdesignat träningsprogram riktat mot power medan kontrollgruppen genomförde traditionell gymnastisk styrketräning. För- och eftertester genomfördes för att utvärdera effekterna av programmen.

This paper is a critique of the hegemonic democracy ideal in France today, the myth of the Republic. Based on critical theory, the paper also contains a normative attempt giving the chance to subaltern groups to tell their, less often heard, version of the "truth".The theoretical foundation is the ontological narrative perspective, where identities and actions are understood as being constructed by the telling of stories. The interdependent relations of different narrative dimensions are analyzed. The power over who gets to tell the story of the "truth" is understood as decided in the interaction by dimensions of metanarrativity, public narratives, ontological narratives and conceptual narrativity. The author argues, inspired by Chantal Mouffe, that consensus is an illusion based on exclusion of those that differ.

The amount of cargo has since the 1970s increased in Sweden and the road traffic accounts for a large part of the transported volume. In Stockholm County the amount of cargo is calculated to be doubled in size from year 2001 to 2020 which means a greater need for transport is required. Much of these transports are being carried out by haulage companies of varying sizes which acts externally as carriers for their customers. All of this despite a greater awareness, laws and demands regarding environmental performance.The trend shows that the haulage industry in Sweden are moving towards fewer but larger haulage companies, which means that the competition is getting tougher for the smaller haulage companies. Smaller haulage companies and research about their competitive strategies is a neglected part of this industry.

No one believes in Åkesson - a comparative study on the evening press and the publicservice reporting on the Swedish Democrats before the 2014 election.The purpose of this essay was to study how Aftonbladet and Ekot reports about the SwedishDemocrats before the election 2014, as well as comparing the two medias and reasoningabout their agendas towards the party. The tabloid, Aftonbladet, is one of the biggestnewspapers in Sweden, which depends on counter sales and commercials. Ekot, which is apart of public service, is state-funded and regulated by certain guidelines. Using aquantitative method we studied 80 articles, and through a qualitative method, six of thearticles were analyzed to reach a deeper understanding. The theories primary used in thisstudy were agenda-setting and framing, to stress the power of media.

Det kan vara svårt att göra korrekta bedömningar i konflikter likt Afghanistan idag. Nato har definerat insatsen i Afghanistan som en Counter-insurgency (COIN)-operation. Osäkerhetsfaktorerna är många och där skiftningar i framgångarna varierar kraftigt över tiden. Det gör också att i många fall måste det finnas parallella processer för det säkerhetspolitiska arbetet. Komplexiteten med detta har gjort att det har utvecklats multifunktionella strategier.

This study aims to make out, which notions and ideas about gender and sexuality that comes into expression in the description of the deviant youth. This study is a narrative analysis, based on a queer theoretical approach. The queer theory directs attention to the normative frameworks on gender and sexuality. Queer theory also illustrates the relationship between the normative and what is considered abnormal/deviant. The study's empirical basis is 8 legal texts, legal documents formed in a Swedish context, which include the welfare state´s judiciary and social services.

The purpose of this study is to find out which attitudes, norms and values exists about lesbian, gay, bisexual, and transgender (LGBT) families in preschools. Based on five qualitative interviews with teachers that work at a LGBT-certified preschool and one that is active in their work with norm critical pedagogy. To be able to fulfil my purpose of this study I concentrated on why these teachers believed that it was of importance to counter society?s heteronormativity, to prevent discrimination and mistreatments towards children and their LGBT parents in preschool. I wanted to find out what the teachers thoughts were on the concept of what a family is and how the diversity of families is shown in the preschools material and pedagogy.When I analysed the results of my qualitative interviews I used queer theories that include heteronormativity and norm critical pedagogy.

Kvävgas kan inte tas upp direkt av växter men genom biologisk kvävefixering kan vissa symbiosbildande bakterier omvandla kvävgas till ammonium. Med bakteriens hjälp kan en växt tillgodogöra sig ammonium och på så sätt bilda protein. Ett exempel på denna typ av symbios är den som kan uppstå mellan en särskild grupp av bakterier, Rhizobium ssp och baljväxter, så kallad rotknölssymbios. Detta är ett exempel på en ekosystemtjänst, en fördelaktig interaktion mellan växt och mikroorganism, som gynnar alla parter, inklusive människan som odlar baljväxten. Hur allmän förekomsten av Rhizobium genotyper är i svenska odlingsjordar är ej klart dokumenterad och därför är frågan om behovet av inokulering av utsäden fortsatt aktuell.
