Deaktivering av metanisering katalysatorer

A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon Formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon Formation of this catalyst was performed.

Är variation i STFI-tjocklek ett bra mått på kartongs bulighet? : Are variation in STFI-thickness a good measure of uneven surface, bumpiness, on cardboard?

This degree project aim to evaluate if variations of the STFI thickness can be used to assess bumpiness on cardboard. During the project cardboard samples were measured using Bendtsen, PPS, a L&W Formation tester, OptiTopo, Ambertec Formation, the STFI thickness tester and a visual comparison. The different methods were then compared to see if there is any correlations between them. The results showed that the visual comparison and OptiTopo correlates. The STFI thickness tester shows however no correlation with the OptiTopo and visual comparison, thus aren't suitable measuring bumpiness..

Karolinsk Stridstaktik : artilleriets och pikens roll 1700-1712 samt bataljonens stridsformering

From a new perspective, this paper will examine the artillery and the pike role in the period 1700-1712 and the battalion´s battle Formation in the Caroline combat tactics. Carolinian battle tactics were practiced during the period 1700-1721. The results from my study will be compared to existing research opinion regarding the selected subject areas, if the result confirms the thesis or question the existing research opinion. The source material used consists of eyewitness accounts from the period consisting of diaries, memoir, biography, general muster rolls and historical literature covering the subject. The analysis shows that the Caroline artillery took part in 12 battles during the period of 1700-1712.

?Oh shit, kan jag få skägg?? : -

The aim of this study was to explore transsexuals? identity Formation and experiences related to cross-sex hormone treatment, as well as to become absorbed in the narrative approach. To be able to participate in transsexuals? identity Formation, life stories were well suited as a theoretical approach. Life stories can be seen as socially situated actions according to Mishler, where individuals? identity Formation can be seen as both identity performances and identity claims.

Man måste inte tro nånting ? men man måste samtala : Ärkebiskop KG Hammars syn på kommunikation och språk

Archbishop KG Hammar has attracted attention for his liberal position in theology. His view on the role of language and communication is central in several books and articles he has published as leader of the Church of Sweden. One of his main theses is the fact that meaning is created in the encounter between text and reader. He often reiterates: God is relation. This non-traditional dynamic stance has a broad impact not only on theology.

Lycksabäcken, ett riksintresse med komplext deglaciationsförlopp : Presentation av ett möjligt scenario över deglaciationen i området

The area of Lycksabäcken northwest of Lycksele is a national interest of natural conservationbecause of its geological values with many unique landforms. Many of these landforms indicatethat the deglaciation process in the area was very complex. However, the deglaciation process inthe area has not previously been fully understood. The aim is to add to the knowledge of theevents that took place during the last deglaciation. To do this, the glaciofluvial landforms in thearea were mapped by studying aerial photographs with a Wild Aviopreter and a five-day fieldinventory of key areas for the interpretation.

Oosporbildning av Phythophthora infestans i potatis och bägarnattskatta

Potato late blight is one of the most important potato diseases worldwide. The disease is caused by an oomycete called Phytophthora infestans. The host range of P. infestans includes potato (Solanum tuberosum) and hairy nightshade (Solanum physalifolium). Hairy nightshade has recently established itself as an important weed in the southernmost part of Sweden.

"Inte som alla andra" : En kvalitativ studie om en grupp vuxna med Asperger syndrom

Normal children acquire the necessary social habits without being consciously aware of this, they learn instinctively. (Author?s translation from Swedish to English) (Asperger & Frith, 1998, s. 21) This essay is about people who do not learn to socialize, the social habits, instinctively but through conscious learning. We have interviewed three adults with the diagnosis of Asperger syndrome with the aim to let them tell us about what it means to have a neuropsychiatric disability.

Hur maten blev begriplig : En analys av matens diskursiva formationen bland Slow Foodmedlemmar i Göteborg

The aim of this essay is to analyze the discursive production of Food, within the Slow food movement, by its members. Through a discourse analysis inspired, theoretically and methodically, by Michel Foucault, this essay examines how the idea of food ? that is ?what should be eaten? ? in opposite to what can be eaten, is constructed within by Slow Food members in the Gothenburg area. The essay analysis how Slow Food?s food discourse is structured and what results this Formation has on food within this discourse.

Pensionärers identitetsskapande i åldrandeprocessen

The study investigated pensioners? forming of identity during the ageing process and the correlation between norms and identity. Previous research has shown that there are norms and notions about elderly and what growing old well implies. There is missing research on the level of the individual with norms, ageing and the process of identity Formation. There is a large population of pensioners in Sweden and the authors behind this study wish that the results of it will help study counsellors to approach pensioners? in a norm critic way.

Elevers användande av strategier inom tal i bråkform vid behandling av diskreta mängder

Syftet med denna kvalitativa studie är att beskriva variationen av strategier som elever använder sig av vid behandling av diskreta mängder inom tal i bråkform, då uppgifterna är av varierad art och där objekten är ordnade såväl som oordnade. För att erhålla ett brett underlag genomfördes uppgiftsdiagnoser, på 78 elever i årskurs sex, vilka utifrån elevernas svar och anteckningar analyserades för att identifiera förekommande strategier. Analysen resulterade i elva skilda strategier inom fyra övergripande kategorier: heltalstillämpning av tal i bråkform, Formation av helhet, Formation av enhet och operation på och med tal i bråkform.De ingående strategierna i kategorin heltalstillämpning av tal i bråkform nyttjar bråkuttryck som heltal på så vis att de ingående talen antingen utgör ett antal objekt eller ses som föremål för en operation. Inom Formation av helhet ingår strategier inom vilka eleverna på olika sätt delar upp helheten utifrån nämnarens storlek medan strategierna inom Formation av enhet har det gemensamt att eleverna utifrån sin förförståelse grupperar de ingående objekten i enheter. I vissa fall samlar eleverna objekten i större grupper medan elever i andra fall ser till varje enskilt objekt.

Dataspelsarvet - klassiker och kanonisering

This master thesis deals with computer game classics and a possible computer game canon. It looks closer at four computer game genres - adventure, RPG, action and strategy - in order to discern which games are considered classics and what characterizes them. To answer the first question a quantitative research method was used. 675 computer game reviews from 5 Internetsites were examined in order to see which games are mentioned most often in this context and therefore might be considered classics. To answer the second question a qualitative research method was used.

I väntan på framtiden : en studie av mindre företags förberedelseinför framtiden

Introduction: The world is changing rapidly and the uncertainty that characterizes today´s society makes companies preparations for the future crucial. Purpose: To examine how CEO:s in small companies look at the future and what kind of preparations they make in order to meet it. Hereby, our ambition is to find out whether there is a difference between companies working in industries characterized by different degrees of stability. Mode of procedure: The purpose of this thesis has been fulfilled by interviews with four CEO:s from industries characterized by different degrees of stability. Result: The companies working in relatively unstable environments tended to be relatively more flexible and have an emergent strategy Formation process, whereas companies working in relatively stable environments displayed relatively less flexibility and tended to have a planning strategy Formation process..

Kemin bakom framtidens avgasrening : En studie av ureasönderfall under kvävgasatmosfär

The purpose of this work was to provide a better understanding of urea?s decomposition and byproduct Formation in an SCR system on heavy trucks. In my experimental setup with TGA-DSC-FTIR (a combination of two thermal analysis methods and a method for gas phase detection), an FTIR method for urea in the gas phase was developed for the qualitative and quantitative determination of urea and its decomposition products. Chemicals such as urea, biuret, cyanuric acid and melamine of p.a. quality were used in this method development. Beforehand, there was no FTIR method available to detect these substances; hence, the aim of this work was to develop an FTIR method to understand the degradation chain of urea. The combination of TGA and DSC was used for analysis of different samples, where urea, biuret, cyanuric acid and melamine in varying amounts have been weighted in for various experiments in order to study the temperature at which a phase transition or reaction occurs, i.e.
