Undersökning av självspridning av contortatallen i norra Sverige
Over the past 40 years 600 000 ha of lodgepole pine (Pinus contorta ssp. latifolia (Engelm.) Critchf.) has been planted in Sweden (280 000 ha on SCA's forest land alone which represents about 15% of the company's total forest land area). In the early 70's SCA situated a number of experimental stands in order to investigate different aspects of the exotic tree, primarily growth rate. To be able to compare the two species plots with scots pine (Pinus sylvestris L.), this species was also planted at the same time and under the same conditions.
A number of questions should always be raised when exotic species are introduced in an ecosystem. Invasiveness, the pathogen situation and purely ethical issues should be discussed.
Den sovjetiska kulturkampen 1917-1932 sedd genom Bresjnevadministrationens lins. En historiografisk studie.
This Masters thesis is a historiographic study, which aim is to investigate how the Brezhnev administration 1964-82 describes the events taking place during the soviet cultural struggle 1917-32. The investigation is limited to how some of the literary groups, organisations and currents as well as a small number of Russian writers are viewed by the administration. The third and last edition of the Great Soviet Encyclopedia, which is considered as equivalent with the soviet official view, is used as source. The analysis made in this thesis is divided in two parts; the text analysis of the writers biographies is compared with the result of a discourse analysis, whose target is some of the literary groups, organisations and currents during the topical period. The discourse analysis is a pre-analysis, but its conclusions also have a value in itself.
Att främmandegöra det välkända
Our modern swedish society is charactarized by peoples and cultures from all over the world. In this perspective I believe that young pupils of today need culture studies in school in order to understand themselves and further to recieve knowledge about different cultures, traditions and lifestyles. The present study is an attempt to investigate the potential of the ethnological culture analysis as a pedagogical method. The paper is divided into two sections; one in which I (a student teacher in swedish language training) have applied the culture analysis in a literary context. By using the culture analysis on Emily Brontë´s classic book Wuthering Heights I have tried to let typical elements from the Victorian era appear.

Examination of mycorrhizal associations of Allanblackia stuhlmannii : a tree under current domestication
Allanblackia is a tree genus native to humid forests in West, Central and East Africa. Its fruits contain large seeds from which edible high-quality fat can be extracted. In order to create a sustainable supply chain of Allanblackia seeds, a domestication program has been initiated with the purpose to enable smallholder farmers to grow the tree as an agroforestry component and cash crop. More knowledge is required to understand the tree?s biology and possible symbioses involving soil microorganisms with plant growth enhancing poten-tial.
Val av tidpunkt för markberedning vid naturlig föryngring under skärm av Pinus sylvestris i Svealand : Timing of scarification when using natural regeneration in seed tree stands of Pinus sylvestris in Central Sweden
This thesis is built on a field study that was carried out in two seed-tree stands near by Götbrunna in Uppland, Sweden. The aim was to examine if scarification carried out in spring time could generate a more dense seedling establishment when using natural generation, than scarification carried out in autumn. It was also investigated whether there were differences in mortality the first season between the two plot-types. Plots were established block-wise with 50 blocks (pairs) on each site. The spring scarification was made with a hoe during 22-23 of April.
Den offentliga bilden av äldreomsorgen : en diskursteoretisk analys av artiklar i Dagens Nyheter under 2006
The purpose of this essay has been to examine the public`s view of the Swedish eldercare during 2006. This study uses discourse analysis as a research method, the reference material has been articles from the newspaper Dagens Nyheter. The aim of the research has been to find central themes, conflicts and consensus in the discourse of eldercare. The analysis resulted in four main subjects which were based on four main questions; the questions of responsibility and execution, the question of contents, and the question of where the eldercare should take place. The analysis of conflicts and relations of consensus in the discourse of eldercare resulted in two different main views; the traditional and a more modern.
25 år senare : en nyinventering av keramiken på Ajvide
This thesis examines a sample of Pitted Ware pottery from the Gotlandic site of Ajvide in regard to the spatial and temporal relationship of the shards. Ajvide Stone Age site have been extensively excavated over the past 25 years and the most recent analysis of pottery was carried out by Inger Österholm in 1987 and new analyses of the material are therefore greatly needed. Pottery from three sample areas was analysed in regard to their distribution, decoration, fragmentation, part of pot and quality of the goods. To analyse the material in a contextual way a multivariate statistical analysis called correspondence analysis was used. Two areas denominated ?dark areas?, which Österholm defined previously, as possible ritual sites, and one reference area with mixed material were chosen for the analysis.
Allmän barnvaccination mot humant papillomvirus för flickor, en cost- benefit analys.
Introduction: Every year about 450 women in Sweden are diagnosed with cervical cancer, almost 200 die and thousands undergo surgery because of cell changes in the cervix. A HPV infection can lead to cervical cancer and therefor costs for the society. The implementation of a vaccination program against HPV is a way to avoid these costs. Aim: The study aimed to calculate the economic impact of the HPV- vaccination program for children in Sweden through a cost-benefit analysis. Method: In this analysis, status quo was compared with non-administration of the HPV-vaccine for the selected cohort of ten-years-old girls in Sweden.
Konsekvensanalys av dammbrott vid Tjärnviksdalen
This report consists of an anlysis of the imapct of a dam failure at Tjärnviksdalen in Ragunda, Sweden. The analysis is conducted using the EU model for environmental impact assessments, as well as a group interview. The presentation of the results in the form of a map where the water level has been raised to the level that the County Board of Jämtland considers to be possible in case of a dam failure.The result of this work is a detailed analysis of the consequenses that a dam failure would cause, the result consider everything from the direct consequences of the water column to an analysis of the chemical changes that the water would undergo.Parts of the analysis have shown that the purification centre and the old deposits will have the biggest impact on Hammarstrand. Both the purification centre and the deposits will realise chemicals to its nearest environment and because of the flooded purification centre the city will not have the ability to clean the water. .
"om du vill ha en riktig vän - köp en hund" : en granskning av Aftonbladets framställning av Jan Stenbeck före och efter hans död
In this essay I have studied Aftonbladets portrayal of the Swedish businessman Jan Stenbeck and if the reporting changes before and after his death, and if so, in which ways. With help from a qualitative syntax analysis and a content analysis I studied my material about Stenbeck during the time period 2000-09-19 to 2004-09-19. In my quantitative analysis I studied 140 articles and in my syntax analysis I studied ten articles, five before and five after Stenbecks death. The theoretical perspectives that I applied in my study is Sigurd Allerns theory about tabloid papers novelty criteria and Adam Shehatas theory about Framing. Allerns theory describes what criteria the tabloid papers have on news and Shehatas theory about framing describes the political forces behind the news who wants to set their own agenda.
LIDAR-analys av flygsanddyner i Västerbottens inland : Har dynmorfologi bildad under tidigare interstadialer bevarats i landskapet?
The aim of this study was to map the prevalence of aeolian sand dunes in Västerbotten, northern Sweden to find dunes formed during earlier deglaciation phases, which was then preserved in cold-based conditions during the youngest stadial of the Weichselian glaciation. These preserved dunes were expected to be covered by a layer of till and have a rather faint morphology compared to dunes formed during the Holocene. Consequently, high resolution LIDAR-derived images from the Swedish mapping, cadastral and land registration authority (Lantmäteriet) was used to detect the dunes throughout an area covering most of Västerbotten, above the highest coastline and below the mountain range. The analysis resulted in several new findings of aeolian dunes compared to the findings in the quaternary soil map created by the Geological Survey of Sweden. Despite the fact some of the dunes at the LIDAR-derived image had a strange faint appearance, it was quickly evident during the fieldwork that the aeolian sand was not covered by till on any of the dunes visited.
Silver och vismut i plaster och färger : Källor till förhöjda halter i slam?
Chemical substances are spread diffusely and uncontrollably as a result of the increased consumption of goods. REVAQ is a certification system that works to reduce the flow of hazardous substances to Swedish treatment plants and to create a sustainable nutrient recycling. According to REVAQ, the yearly accumulating rate of metals should not exceed 0.2% in soil per year. Silver and bismuth are two metals that do not fulfill this requirement. The silver concentration in sludge decreased during the last decade, however the last few years, it has leveled off.
