Storjuktan ? Rekonstruktion av ett sekels kvicksilverbelastning. : En undersökning av kvicksilverkoncentrationer i daterat bottensediment.

The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.

Fröåtjärns föroreningshistoria : Utredning av hur metallbelastningen varierat över tid med hjälp av sediment som ett naturligt historiearkiv

The metal mining history goes thousands of years back. The downside of the mining industry is the large amount of tailings created during the mining operations. Drainage and leaching of heavy metals from these tailings may cause major environmental problems including acid mine drainage and leaching of heavy metals. This study examines a pond located near an old mining site, where part of the old mining facility has been recently (1990) restored. The objective was to assess eventual metal contamination from historical mining and the recently performed restoration using a sediment core as a natural archive of historical metal inputs to the pond.

Från Snövit till Frost : En genusstudie av kvinnliga relationer iDisneyfilmer och hur dessa har utvecklats över tid.

This study examines how women are portrayed in four of Disney?s feature films, withthe focus on the presentation of relations between women. The films examined areSnow White and the Seven Dwarfs (1937), Sleeping Beauty (1959), The Little Mermaid(1989) and Frozen (2013). The aim is to analyse the development that has taken placefrom a gender perspective, from the earliest film, Snow White and the Seven Dwarfs(1937), to the latest, Frozen (2013), and to reveal the significance of the femalecharacters for each other. The films? portrayal of women and female relations isdiscussed in relation to previous criticism of Disney for their stereotyped portrayal ofwomen, and through a thematic comparison with the known fairytales on which thefilms are based.

Vattensork och åkersork - skadegörare i svensk fruktodling

There are two species of voles that cause damage in Swedish fruit production: the water vole (Arvicola terrestris) and the field vole (Microtus agrestis). Both species make the most damage during the winter season. The water vole makes subterranean burrows and cause serious damage by gnawing on the tree roots. The field vole seldom makes burrows and gnaws the bark at the base of the tree trunk. In recent years there have been several reports about increasing vole damage.

Levande material. En utforskande exposé över vårt förhållande till kroppen som organisk materia

In this project the author made an attempt to, in a short film, visualizean experience of the organic materials that our bodies consist ofand what becomes of it when we die. The intention was to dissect thismatter, break it down to see it in a simpler form and to explore ourrelationship to it, being part of a constant exchange between organicmaterials and having so much power over the environment and otherliving animals. At the very start, the idea was to deal with the relationshipdifferent people have with their bodies. Later in the process, a decisionwas made that the product would be communicating the author?sown experiences of the body materials after studying it and trying torecreate fragments and feelings of them.

Analysis of Quality of Service of Wireless LAN for IEEE 802.11e

Nowadays Wireless LAN is playing a more and more important role in network systems. After 1999, in which the IEEE organization published its Wireless Local Network standard 802.11[1], many people saw the advantages of the standard but also the lack of support for multimedia streaming. A lot of research work has been done on the proposed IEEE 802.11e standard draft during the past 4 years. It is supposed to be able to fully support Quality of Service. The final version will be published early in 2004.

Miljövärdering av resurssnål betong med införande i BIM

This thesis aims to illustrate how environmental impact can be reduced, through the use of lean concrete. It also illustrates how environmental data can be applied to a house through implementation with BIM. In this study a unique concrete structure developed by Swedish Cement and Concrete Research Institute is assessed for environmental impact, by calculating the carbon dioxide equivalents using LCA methodology. The construction is a sandwich element where the concrete is made ??up of three layers.

Flustret : en nattklubb utomhus

Flustret is a restaurant and an entertainment place situated by Svandammen in Uppsala. It all began in 1842 as a café serving coffee, tea, chocolate and pastry. During the years the building has had numbers of different owners. The owners of today are running Flustret in a same friendly spirit that has been characteristic from the beginning. The buldings history is now approaching an age of 165 years. Throughout the years different historical layers have been placed on top of each other, leaving a layer of patches.

Påverkan från den förväntade klimatförändringen på tillväxten i norra Sveriges skogar : En litteraturanalys

This is a literature review of how the climate change affects the forest growth innorthern Sweden. The temperature will rise about 5 °C with the largest increase in thewinter season (December - February) and the CO2level in the atmosphere is expected tobe doubled. Precipitation patterns will change and increase with 25-35 % and theprecipitation will be in form of rain rather than snow. Today the forests in northernSweden are entirely dominated by coniferous stands. This may shift with the climatechange and results in a larger number of deciduous trees, preferably birch will becomestronger and grow better and faster.

Effekter av upphörd hävd i Lurö skärgård : Har diversiteten av kärlväxtarter förändrats?

One of the main reasons for the massive loss in plant species diversity is the fragmentation of habitats. In Europe, open pastures and meadows are the habitats going through the most changes during the 20th century, according to the agricultural changes. In this study vascular plants were invented at five different islands in the Lurö archipelago, Vänern, Sweden. The aim of the study was to sort out whether the diversity of plants has gone through any changes in abandoned managed grasslands compared to continuous managed grasslands. The aim was also to study if a change in the landscape has made any differences for the species development or decline.

"And the World has Somehow Shifted." : En kvantitativ studie av genuskonstruktioner i Walt Disney Pictures animerade långfilmer

The Disney princess line includes nine films, in our study we have extended this line to include the latest three films from Walt Disney Pictures that follow the same pattern. These films are Tangled (2010), Brave (2012) and Frozen (2013). We have conducted our study using the same method used by England, Descartes and Collier-Meeks (2011) in their study of the first nine films, starting with Snow White and the Seven Dwarfs produced in 1937 to Princess and the Frog from 2009. A quantitative study was executed where we focused on gender role portrayal, the main characters behavioral characteristics and performed rescues. We applied the following theories to our result; the Social Constructivism, Laura Mulvey?s theory of the Male Gaze, Michel Foucault?s theory of power and discourse, intersectionality and Claude E.

Studier av habitatval och revirstrukturer hos vassångare (Locustella luscinioides) i Tåkern

The Savi?s Warbler (Locustella luscinioides) is a recently established bird species in a few reedy shallow lakes of southern Sweden and has only been found nesting for the last twenty years. Little is known about the species' habitat preferences, breeding biology and demands for specific territory structures at breeding sites in Sweden. Knowledge of a newly established species? habitat requirements is essential to maintain a viable population and design action plans.
