Gestaltningsförslag till ny förskola på Zakrisdal
Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.
Man och kvinna i tvåsamhet, Amen : en studie om debatten kring samkönade äktenskap i religiös media
The purpose of this thesis is to present a number of examples of how the debate concerning same-sex marriages in Sweden was conducted in religious media between the year of 2005 and May 1st 2009. I intend to examine if and how these debate articles can be descibes as examples of religion taking part in the public sphere according to José Casanovas theory of deprivitization and public religion (1994) and Jürgen Habermas theory of religion in the public sphere (1964, 1989, 2006, 2008). I will apply the theories to the material by using four criteria for public religion, based on Casanovas and Habermas two theories, designed by Marta Axner. I also intend to compare the arguments used in the material to the arguments found in Marta Axners dissertation Public Religions in Swedish Media (2013). To identify these arguments a textanalysis containing seven argumentschemes, designed by Gunnar Björnsson (1994), is applied.
Doula - Ett positivt komplement för fäder i samband med barnafödande : Kvalitativ intervjustudie med några fäder
Title: The nurse's dilemma in psychiatric inpatient care - a balancing act between good and evil Objective: To describe the nurse's experience of relieving patient suffering caused by coercive measures on a closed psychiatric ward . Frame of reference : The results are discussed in light of Eriksson´s theory of suffering and caring relationships Method: A qualitative analysis based on focus group discussions Results: The analysis resulted in six categories, to protect the patient , to involve the patient , not to lose control , to remain , to justify compulsion , and to be touched . The results showed that nurses had the experience of being able to relieve the suffering of patients caused by coercive measures. It was also found that the nurses had a tendency to justify coercive measures , the more experience they had of performing these . Conclusion: The results describe that nurses have the experience and knowledge of how to relieve patients' suffering caused by coercion but also their experiences of performing these .
"Säg mig vad du äter och jag ska säga vem du är" : En kvantitativ studie om efterfrågan av hälsosamma livsmedel
Obesity and overweight are today classified as one of the largest epidemics in the Western world and is threaten a large part of the population. As a reaction to this a major health trend has emerged in recent decades. Every day consumers are exposed to information from the media about what is healthy or unhealthy to eat and the recommendations change frequently.There is great interest in healthy food on the Swedish food market, but still healthy foods only represents a small proportion of the total food sales. The essay examines the gap between the current and potential demand for healthy food and if it can be explained by any of the following factors: lack of information, price, taste or cognitive behavioral.To study these questions a quantitative method have been used and 213 questionnaires were collected. The intention is to draw general conclusions about the entire population.
Slithållfastheten för dentin och cement i förhållande till emalj in vivo hos häst
The female dog has a unique reproductive endocrinology, with high levels of progesterone throughout the 70-day long luteal phase. In this project, markers of glucose metabolism were studied and compared from the aspects of breed group and time in oestral cycle. The parameters studied were: glucose, insulin, progesterone, fructosamine and the newly introduced analysis of HbA1c. Hba1c was also further evaluated and discussed as a diagnostic tool in canine medicine.No differences in terms of glucose markers were found between a group of purebreed dogs of various breeds compared to a group of dogs with high risk of dioestrus diabetes, namely the Norwegian and Swedish elkhounds.No differences were found between the two sample occasions, anoestrus and dioestrus, concluding that there is no need for relating test results to the time of the oestrous cycle in middle-aged intact female dogs.There were statistically significant higher values of all glucose markers in diabetic dogs than in non-diabetic dogs. When it came to HbA1c, however, there was a larger overlap between the two groups, compared to fructosamine.

This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.

"Vilka bilar är lika stora?" : insamling av referensdata för språkförståelse med hjälp av bedömningsmaterialet Sofialådan
I denna studie har insamling av referensdata över språkförståelse hos treåringar med typisk språkutveckling genomförts. Till detta har bedömningsmaterialet Sofialådan (Westerlund & Öfverholm-Engström, 1995) använts. Sofialådan bygger som flera andra språkförståelsematerial på den s.k. act-outmetoden där man låter barnet agera med föremål efter en given instruktion. Med hjälp av föremålen i Sofialådan bedöms barnets förmåga att identifiera grundfärger och storleksbegrepp, kategorisera, flytta föremålenligt olika prepositionsanvisningar samt att följa flerledade instruktioner.
Förbättrad lönsamhet i växtodlingsföretag! : en ekonomisk analys av ett samarbete i form av ett driftsbolag mellan två lantbruksföretag
The agriculture is today in a development that leads to bigger and bigger units in the primary production. To be able to follow this development many companies chooses to cooperate in different ways. The most radical change is when farmers fuses with other farmers and merge into to a big collectively owned operation firm. The reason behind this idea is that the firms achieve the big companies advantages by being complement to each other. The purpose of this essay is to make an economic analysis of two crop production companies who works together in an operation firm.
