Förbränning av träpellets och pelleterad halm i en 40 kW rosterreaktor
The project focus on combustion of softwood pellets and pellets in a 40 kW grate fire reactor at TEC-Lab. Dept Applied Physics and Electronics at Umeå University. Experiments were performed at four primary airs to fuel ratios (0.7 to 1.3), where aspects such as temperature profile, levels of gases (CO and NO), sintering-/-slagging and unburned fraction of the ashes were studied. Four different fuel loads were used for wood pellets (10, 20 and 30 kW) and one fuel load for straw (10 kW). Combustion of straw proved very difficult to ignite, and also led to other combustion-related technical problem such as slag formation due to the relatively low melting temperature-/-slag temperature of the straw.

Kunskaper om, och erfarenheter av munhålecancer hos tandhygienister i Sydöstra Sverige - en enkätstudie
Year 2004 nearly 1000 new cases of oral cancer were diagnosed in Sweden. An early discovery increases the chances for survival remarkably. The dental profession has an important role in detecting oral cancer. Considering that dental hygienists probably will have a greater responsibility in the future when it comes to examinations, knowledge of oral cancer will be important for this profession. The aim of this study was to examine the dental hygienists knowledge of Oral Cancer in the county of Blekinge, Kalmar and Kronoberg, as well as their experiences in detecting oral cancer.
Släktforskare ett nödvändigt ont? En undersökning av bibliotekariers och släktforskares attityder gentemot släktforskning på bibliotek.
The aim of this thesis is to examine how librarians and family historians experience their interaction at the reference encounter, what influences these views and how they affect the service; whether the family historians are aware of these views; which subject knowledge is needed and how this knowledge affects work performance; if there is a need for continuing education, and finally, if the family historians themselves can work as a resource for the library or the librarians? The thesis consists of three parts; in the first a theoretical frame was constructed around the concepts service, continuing education, subject knowledge and attitudes. Role theory was used as a theoretical background to show how expectations influence professional roles. The second part consists of the results given from the qualitative interviews with librarians and surveys with family historians that were performed. In the last part a discussion from the theoretical and empirical information earlier received was made.

Gradering av vindkraftslägen i Lerums kommun med hänsyn till infrastruktur och läge
The aim of this master thesis was to find and grade suitable sites for wind turbines in the rural district of Lerum at the reguest of Göteborg Energi. The rural district of Lerum consists of very complicated terrain which was the reason why we picked Lerum.The assignment was achieved by using the software program ArcGIS and its attendant tools. In step 1 an overall analysis was made in order to sort out the least suitable sites. Step 2 consisted of a 3D analysis in ArcScene together with a more precise analysis in ArcMap. As result we found two interesting sites, which met our demands and specific constraints.

Aegishjalmur, tyrrunan och valknuten : En kvalitativ studie i användandet av fornnordiska symboler bland nationalistiska rörelser.
The students participating in my development work will work with a process book for handicraft studies. In the beginning of their studies, the students need practical knowledge about the development of the profession itself, but they also need to be challenged and learn how to solve problems on their own which will help them gain a deeper knowledge of the subject. I focus on open questions to create a process with the students. This process is created when working with Solution-Focused-Education. Through ?assessment for learning? we can help the students to improve their self-assessment and understanding of the learning process.
