Avena Sativa - En hyperackumulator? : En studie av havres kadmiumupptag
The aim of our research was to investigate if oat is capable of extracting cadmium to such extent that it is usable in decontaminating polluted soils. We grew oat in a hydroponic culture during 28 days in a controlled environment and a total of 30 plants were used. The nutrient solutions were contaminated with cadmium of ten different concentrations after seven days. After harvesting the plants, the roots were separated from the shoots, placed in separate containers and then turned to ashes. The cadmium content was measured three times per sample in an atomic absorption spectrometer.Our results indicate that the ability of oat to extract cadmium from a solution is linearly dependent of the cadmium concentration of the solution.
Datorn på fritidshemmet : Elevers och fritidspedagogers uppfattningar om datorns användning på fritidshemmet
Syftet med studien är att undersöka elevers och fritidspedagogers uppfattningar om datorn och användningen av den på fritidshemmet.En kvalitativ metod med en induktiv ansats har använts i studien.

The study is also looking for answers on whether and how the plates are used to develop children's scientific knowledge. There are six teachers and 14 children's statement that forms the basis for the analysis. The results indicate that tablets are used for two purposes.

Mortalitet och skottskjutningsförmåga hos ek (Quercus robur) efter brand :
In this study I analysed how burning affects sprouting ability and survival of oak (Quercus robur) during the first season after a burn in southern Sweden. The study
consisted of two separate field tests; in the first, two 300 m2- plots in western oak
dominated forest were burned to analyze the fire behavior and the immediate mortality of oak and beech seedlings defined as individuals (> 20cm of height). At the end of the season almost 50% of the oak seedlings had resprouted while the beech seedlings had 100% mortality. An attempt to investigate the effect of the burn of artificially sown acorns was totally ruined by wild boar grouting before any conclusive results could be seen.
In the second test the resprouting ability of oaks of varying diameters (average BHD 7-9 cm, range 2-42 cm) was examined one season after a prescribed burn in southeastern Sweden.

Design i fysisk gestaltning - Design in embodied communication
Studien undersöker hur fysisk gestaltning i pedagogiskt drama formas under ett lärotillfälle i skolmiljö. Studien använder sig av ett socialsemiotiskt synsätt och en multimodal ansats för att undersöka eleven som utövare av fysisk gestaltning. Fysisk gestaltning betraktas som ett medium och sammanhanget analyseras utifrån ett designteoretiskt perspektiv på lärande. Två grupper elever i 10 års-åldern har filmats och observerats. Resultaten visar att påverkan från regler i skolan, instruktioner och pedagogen beskriver elevernas formella design.

Implementation av ett kunskapsbas system för rough set theory med kvantitativa mätningar
This thesis presents the implementation of a knowledge base system for rough sets [Paw92]within the logic programming framework. The combination of rough set theory with logic programming is a novel approach. The presented implementation serves as a prototype system for the ideas presented in [VDM03a, VDM03b]. The system is available at "http://www.ida.liu.se/rkbs". The presented language for describing knowledge in the rough knowledge base caters for implicit definition of rough sets by combining different regions (e.g.
Att hitta Ett hem vid världens ände: Om sexualitet och könsidentitet vid ämnesordsindexering av skönlitteratur.
This master thesis aims to examine the process of indexing fiction when it comes to area of sexuality and gender identity. The empiric work that forms the basis of the thesis are three investigations:(a) examining the current status of indexing fiction within the catalogues of six Swedish medium-sized libraries;(b) interviewing librarians who allocate the subject headings; and(c) an analysis of the Swedish subject heading system Att indexera skönlitteratur.This will be concluded with an analysis of the gathered material through queer theoretic standpoint with the help of critical classification and its inclusion through separation, and marginalization where subjects that differs from the norm is included but only by being separated from the norm, or ignored totally. This will show that there are similarities with how different groups get treated within the classification systems and how they are treated in subject heading indexing. An example of this in Att indexera skönlitteratur is that heterosexuality never is mentioned in the subject heading but is always present as the silent norm, while gender identity is marginalized through exclusion of the subject heading, and related words are instead being included under sexual identity..

Arbetsplatsmobbning : - Är inte att kleta senap på någons brallor!
The focus of this thesis is on what is considered to be a suitable foster home. For the study to be carried out an application had to be made to get access to the foster home assessments in a medium-sized municipality in Sweden. With the support of attachment theory and theory of standards different categories have been picked out and analyzed in foster home assessements that have been approved. The conclusion to what is considered to be a suitable foster home is a complex issue, as there are many factors that are interacting. Social workers seem to focus on the importance of a family?s ability to provide some kind of stability and security for a child who is considered to be placed within their home.

Affischen - Ett döende medium? : En kvalitativ studie av evenemangsaffischering
As students of graphic design the craft of print is close to our hearts. One of the most essential mediums of the evolution of printing techniques is the poster. In a world where digital mediums are being utilized to a greater degree everyday, our love for the printed poster makes us wonder if the days of the poster are counted.What we did was to take a closer look at the role of the poster in promoting events. We focused on the Stockholm area and did qualitative interviews with three different event promoters. Live Nation which is an international live entertainment promoter, Dramaten which is one of Sweden?s most well respected theaters and Stockholm Live which is a stand up comedy promoter in Stockholm city.From doing this we learned that economics play an important part in defining the role of the poster.
