Kraftspelsanalys av transportstag : Prefabricerade väggelement i betong
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.

Några grundskollärares uppfattningar om kulturell mångfald, värden och kunskap tolkade som ideologi
AbstractIn this study, the conceptions of a number of teachers in the Swedish primary and lower-secondary school about cultural pluralism, the values connected to this pluralism by the Curriculum for the Compulsory School System, the Pre-School Class and the Leisure-time Centre, Lpo 94, and the possibilities for pupils to gain knowledge about these values, were studied. The conceptions of the teachers were regarded and interpreted as ideology, since the study was made from a point of departure containing an assumption about how the content of the curriculum is of importance for the development of relations of power and dominance between different groups in society. The purpose of the study was to interpret the statements of a limited number of teachers about cultural pluralism, values and knowledge, regarding the ontological, axiological and epistemological assumptions and conceptions expressed therein. The empirical data of the study was gathered through qualitative interviews with eleven teachers working in six different primary and lower-secondary schools in the Mid-Sweden region. The conceptions expressed in the statements given by the respondents were categorized.
Gis och realtids-GPS på renar : renens habitatanvändning i brukad skog - två vintersäsonger i Vilhlemina Norra Sameby
This study is commissioned by the Swedish University of Agricultural Science (SLU - Department of Forest Resource Management) in coorporation with Sveaskog and Vilhelmina Norra Sami reindeer herding community. The purpose of this study is to analyse movement patterns and habitat use of reindeers during two winter seasons (2005/2006 and 2006/2007) in areas affected by forestry activities such as clearcutting. This study examines the possibilities of analysing information from Reindeer husbandry plans and forest variable data from kNN and SMD, in relation to GPS collar points from reindeers by using Geographical Information System (GIS). Lack of knowledge and understanding between the reindeer industry and the timber industry has often led to heated debates. The possibilities of using this type of technique are very interesting and could increase knowledge concerning land-use issues to different resource users.
The main results from analyses comparing SMD, kNN, data about clearcuts, and GPS collar points from reindeers indicates that clearcut areas, younger forest, coniferous forest on lichen-dominated areas and areas dominated by pine was preferred by reindeers during the winter period.
Demokratisk fred : Resultatet av FN-interventioner ur ett demokratiskt perspektiv
The UN was established after the Second World War. The organization?s primary goal was to maintain peace among all nations. When the UN intervenes in other states affairs, it is violat-ing the principles it is set to defend, principles of non-intervention and respect for sover-eignty. The outcome from such interventions is very important, a result that can legitimize the action.
Den oväntade kändisen: - Effekterna av överraskande kombinationer mellan varumärke och kändis i reklam
The effect of moderate incongruency between a celebrity endorser and an advertised brand is considered in an experiment with celebrities, both congruent and moderately incongruent with the investigated brands. In addition, the influence of possible moderator variables was examined, as well as the potential impact of the celebrities? gender. It was found that an ad exposing a moderately incongruent combination of celebrity and brand generated a more positive result on attitude towards the ad, brand attitude and word of mouth. Furthermore, under some conditions certain moderator variables influenced the relationship between moderate incongruency and responses evoked by the ad..
Escherichia coli-mastitis in dairy cows :
Escherichia (E) coli is one of the most common udder pathogens associated with acute clinical mastitis in Swedish dairy cows. The aim of this study is to review some of the existing literature on E coli mastitis from a Swedish perspective. The bacteria, its most important characteristics, and diagnostics under field conditions is covered, as well as what happens during infection, how E coli affects the cow and which consequences this have. Clinical symptoms associated with E coli mastitis are described and information on when these cases of mastitis usually occurs is given. Risk factors in the cow?s enviroment are described as well as the importance of the cow?s immune defence.
Effektiva lösningsmetoder för Schrödingerekvationen : En jämförelse
In this paper the rate of convergence, speed of execution and symplectic properties of the time-integrators Leap-Frog (LF2), fourth order Runge-Kutta(RK4) and Crank-Nicholson (CN2) have been studied. This was done by solving the one-dimensional model for a particle in a box (Dirichlet-conditions). The results show that RK4 is the fastest in achieving higher tolerances, while CN2 is the fastest in achieving lower tolerances. Fourth order corrections of LF (LF4)and CN (CN4) were also studied, though these showed no improvements overLF2 and CN2. All methods were shown to exhibit symplectic behavior..
Herrelösa katter i Skåne : problem och hantering
The large number of surrendered and feral cats is a big animal welfare problem all over the world. Populations of feral cats arise through a large number of unwanted cats which can lead to surrender of these, through cats allowed to roam free outside which can lead to the owner losing these and through the reproduction that occurs amongst these surrendered or lost cats. One aim of this study is to give an account of this problem. It is however difficult to draw general conclusions about these populations of cats since studies all over the world has been carried out on different types of populations, during different conditions and different periods of time. The welfare of many of these cats is presumably low because they are exposed to risks as disease, starvation, climate, traffic, other animals and humans.
ISO 9001 : En fallstudie om hur de ständiga förbättringarna, som är införda i företagets verksamhetssystem, är anpassade efter medarbetarna
MPC is the company Exova Metech?s operating system that contains all the information needed for the company's objectives and guidelines to permeate the company. How changes in the MPC should be communicated with the company's employees can be seen as problematic. Routines that have been changed in practice, the process owners do not always update in the MPC, it leads to that the employees can not ensure that duties are performed properly. It is therefore important that management takes its responsibility by providing updated information.
Arbetsgivares ansvar för rehabilitering : Vägen tillbaka i arbete, lång eller kort?
Aim and questions: The purpose of this paper is to clarify the responsibilities employers have for rehabilitation and to explore how it conforms to an employers' actual condi-tions. Furthermore, the intention is to increase knowledge of how employers interact with other partners in the rehabilitation process and what affects sick people to return to work. The following three questions form the basis of this paper: What are employers? responsibilities for rehabilitation under the law and how is it consistent with an employer's actual conditions? What is the role of employers in the rehabilitation co- operation with other actors? What factors influence sick people to return to work?Method: The paper has used a true scientific and a legal sociological method to examine how the regulated employer responsibility for rehabilitation relates to what is practical in re-ality. To achieve the purpose, four empirical interviews were conducted with Örebro Municipality, Insurance, occupational health Previa and a doctor, which all of them have an important role in the rehabilitation process.

Ett brev från Herr P : om det personliga hos Björn Lövin
For the Swedish artist Björn Lövin, the personal was a problem. In his first exhibition in Moderna Museet, Lövin observed through the fictitious character Mr. P (for »Personality«) the ruptures in the Swedish welfare state. The exhibition Konsument i oändligheten och Herr P:s penningar (Consumer in Infinity and Mr. P?s Money) (1971) was composed of two environments, through which a veridical working class apartment and a high street with life-sized mannequins and furniture characteristic of its time, visualized the societal discrepancies in the welfare state as well as the art world of the early 1970s.
