Väneramplitud ? Lönsamhet? : Kvalitativ studie av åtgärder, genomförda för att reducera risker och kostnadspåföljder av en förändrad vattenregim
Tappningsstrategin för Vänern ändrades i ett beslut från Länsstyrelsen i Västra Götalands län och Vattenfall AB, på uppdrag av regeringen år 2008. Detta gjordes för att minska risken för översvämningar i Vänern. Åtgärden var föreslagen av Klimat- och sårbarhetsutredningen, som försökt utreda konsekvenser av klimatförändringar för Vänern i ett framtida förändrat klimat. I utredningen används en metod för att mäta kostnader. Metoden är en kostnads-nytto-analys (Cost-Benefit-Analysis; CBA) som användes för att utvärdera bland annat Vänern med omnejd. Enligt denna uppsats saknas det värdering för naturmiljö och sociala faktorer i denna utredning.
I djurisk skepnad : en studie av djurens rituella betydelse i södra Skandinavien under atlantisk kronozon
This thesis concerns the mesolithic relation towards animals and hunting habits among people in Skateholm, Tågerup and Vedbæk - Bøgebakken. The aim is to look at the societies from a cultural point of view and demonstrate that the people living there identified themselves with animals and adapted their lives, their hunting and their burial customs according to rituals and believes concerning animals in their surroundings. The result is convincing and clearly shows that animals where treated differently in manors which can only be explained with specific cultural relations towards different kinds of animals..
Individers upplevelse av att bo och leva i bostadsomra?det Kronoparken
This is a qualitative study made to find out individuals experience of life in the residential Kronoparken in Karlstad. The study is a part of a municipality supported project aiming to find points of improvement and work for the area's development. This study is a first step to hear in what way the residents themselves describe their neighborhood and their lives. A total of thirteen people participated in focus groups with semi-structured interviews as data collection and the study was based on an availability sample which in this case meant that citizens of the residential Kronoparken were asked to participate. Data were analyzed through thematic analysis and in the analysis three themes appeared that summed up what the participants talk about and emphasized most: a divided area, anticipation and valuation as well as a comfortable and healthy every day living.
Produktutveckling av koncept för isbanesystem
Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.
?R KUSTN?RA ALK?RR I BOHUSL?N ETT ?BLUE CARBON? HABITAT?
In coastal wetlands carbon/organic matter can be stored for long periods of time thanks to, among other things, the presence of water which slows down the decomposition. Because of this, restauration and management of such habitats have the potential to decrease the emission of greenhouse gasses and help mitigate climate. Internationally these environments are called ?blue carbon? ecosystems. In Sweden, alder (Alnus glutinosa and Alnus incanata) covered wetlands along the coast is a nature type that potentially could function as a ?blue carbon? habitat.
Konsumtion i den tredje åldern
In this thesis I try to examine the consumtion among people that are retired and therefore can be considered as being in the third age. This studie is carried out in Norrköping, with interviews of people living in or close to Norrköping. I have used theories about the third age, consumtion and the space of the city. I have examined the importance of the city space as a meeting place and where the elderly buy the things they need for there everyday life. I also try to examine if the things they buy has an importance that goes beyond the immediate use, such as communicating a persons status to others.
Kungsmarken, svart på vitt
Kungsmarken, a apartment area in Karlskrona has suffered the medias prying eye for decades. Today the area only maintains a very low position of status in the livinghierarchy in the community. The area in question was a part of the "Miljonprogrammet" and apperantly has suffered the same consequenses as similar areas since it was built. The onesided negative discourse that has persecuded areas of Miljonprogrammet, such as Kungsmarken, has put social problems as criminality, drugaddiction, dependancy on the social welfare system or cultural incompetence in the focus. The author´s previous understanding of the phenomena lies in private experience from living in Hjällbo, a similar area in Gothenburg also with the miljonprogram.
Passivhus av helväggselement i träull
Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.
En studie av projektet Datorn som pedagogiskt verktyg enligt modell 1?1 ur ett lärarperspektiv
In this essay I describe the development of my prose work entitled Jorden a?r platt (Earth is flat). In the text we encounter a woman whose 40-year-old brother is diagnosed with lung cancer. The brother has been living a hectic life of drug addiction. The relationship between brother and sister is characterized by ironic distance, but also a lot of love.
Utformning av hamnområdet i Arvika : stadsbild och offentliga miljöer
The harbour in Arvika is closed down and the industry that has been established in the area is now beeing wound up. A deepened comprehensive plan for the area is under progress in the municipality. The intentions are for instance that the harbour should be integrated with the city and that Arvika is facing a lake should be more apparent from the city center. The harbour should also contribute to a more attractive city. These intentions have hence been the starting point of my undergraduate theses, which has resulted in a proposal on how to develop the harbour.
During the process I have analysed the city image, how the area is used today and the public places in the city centre.
Ung och full : en kvantitativ studie om ungas riskbruk av alkohol
Recent statistic shows that about 28% of adolescents living in Stockholm drink alcohol at such a high level that their consumption counts as risky drinking. The correct term to use in this matter would be binge drinking adolescents. In the more wealthy areas of Stockholm this group of binge drinking adolescents counts for as much as a third of the population. In contrast, the adolescents living in exposed areas do not drink nearly as much. Binge drinking adolescents in these areas only counts for 15%, nearly half as much as in the wealthy areas.In light of this the intentions of this study is to investigate which explanatory factors that can clarify the range-rated differences in binge drinking between adolescents in Stockholm.
Systemlösningar för plus- eller passivhus : En studie med syftet att lösa energibehovet för ett specifikt hus.
The purpose of the house which is the basis of this report is to be able present itself on the market as a relatively cheap and at the same time a climate friendly choice. The house is supposed to be able to be built anywhere in Sweden and the rest of Scandinavia in a short period of time. This puts demand on what kind of heating system the house can have, since not all places have the geographic advantage of being able to use geothermal or district heating. Therefore the heating system choices will only include those that are not limited by their geographic location. The house will be built in modules which only require the groundwork to be done before the house can be erected. In this report "System solutions for plus or passive-housing" a comprehensive literature search has been conducted as well as a number of calculations.

Löslighet och metylering av kvicksilver i en förorenad sjö (Ala-Lombolo) i Kiruna kommun :
Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment.
The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.
