The interest for wind power has increased in Sweden. Northern Sweden is especially interesting due to that a new wind resource map shows that there are areas in Northern Sweden that have more potential for wind power than what have been known before. Therefore E.ON Vind is interested in finding out if, and where, there are suitable places for establishment of wind power in Northern Sweden. The purpose of this master thesis is therefore to perform an inventory of Northern Sweden for suitable places for wind power. The master thesis is performed at E.ON Vinds office at Vasagatan in Stockholm.

This master thesis was initiated with the aim to answer at what level of installed capacity of wind power in the northern parts of Sweden it would be beneficial to improve the transmission capacity from the Northern Sweden. During the process of this work the aim has changed to try and create a model that can be used to analyze how well the hydro power installed in the Northern Sweden can even out the quick changes in wind power production.To create a good model of all hydro power in Northern Sweden is a very large job, unfortunately too large for a master thesis. This report therefore ends with an extensive analysis of the simplifications that have been made and their effects as well as a list of the future work that has to be done.The model that has been created have shown to be effective and produce good results. The conclusions that can be made is that the northern Swedish hydro power have very good possibilities to balance the wind power production. Only a few cases where water have been spilled even though there has been some free capacity has been discovered.

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

Hommage till slit och släp is a tribute and a resarchabout patterns relation to clothes. The primary goalof the project was to examine how a pattern couldchange the apperance of a garment and how thegarment?s construction and material would impactthe pattern. The formative survey was about thesparsely populated areas in the north of Sweden andhow theese areas have been treated by the swedishgovernment. The issue worked as an inspiration andmethod which I used in the patternresearch.

An analysis of Konstvägen Sju Älvar, an exhibition of modern Nordic sculpture along a road trough the wilderness of Northern Sweden. Konstvägen is a project for public art and contemporary art in Northern Sweden. The intention is to see what happens when you exhibit art alongside a road and what function it fills. By comparing the qualities of Konstvägen to the qualities of a monument Konstvägen and it?s exhibitional functions are sought to be understood..

AHA is a Swedish abbreviation of "reveal threatened park and avenue trees" and is a method to assess the conservation value of individual trees, mainly in the park environments but also in natural stands. This method has previously only been practiced in southern Sweden (Sörensson 2008). To see if this method could provide satisfactory results in Northern Sweden, I have studied it in areas around the Umeå River. This was done by studying the relationship between trees with different classifications of conservation value (as classed by the AHA method) and their content of species (species richness and abundance). Insects were collected using trunk window traps in a period of 13 weeks during the summer of 2014.

Restoration projects are planned and carried out in order to reduce the impact due to anthropogenic influence and to achieve at least good ecological status according to the EU Water Framework Directive. The resilience effort of such restorations is however ambiguous. The aim of this study was to evaluate the potential of follow up restoration measures in Swedish lakes and streams. In particular, we visualized the geographical spread of restoration measures in Sweden and quantified the different types of measures that were implemented so far. Further, we evaluated the extent of sampling of biological factors before and after the restoration measures have occurred. For the purpose of our study, we used the recently compiled national database of restoration measures in Swedish lakes and streams.

The number of sawmills in Sweden has decreased dramatically since the 1980s and the trend looks set to continue. The sawmills that are left instead becomes larger and are situated farther apart. In Northern Sweden, they are concentrated along the coastline.In our study, we compared conditions for running a sawmill in inland areas and coastal areas and looked at what factors have the greatest impact on the profitability of the sawmill in Northern Sweden.We chose to compare different locals conditions for a sawmill that only sawn pine timber and had an annual raw material requirements of 300 000 m3ub per year. By analyzing the kNN-data from the Swedish National Forest Inventory we have taken out the size of the timber volume at each site and its catchment. We have also looked at possible competitors in the areas that may affect the purchase price of the commodity.

Productivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) was studied on 12 sites in coastal areas of Northern Sweden. On each site, sample plots were placed in adjacent Norway spruce and Scots pine stands with similar ages in between. Basal area, tree height, Site Index, volume production, simulated maximum mean annual increment (MAImax) and tree vitality were compared for the two species. Average basal area at the time of measurement was 30.4% larger for Scots pine stands than for Norway spruce stands. The difference between the two species in basal area increment during the last 10 years was related to stand age.

Acidification is a central concept in the environmental debate. The effect of acidification of the soil is a matter of a decreasing amount of cations and thereby a decreasing ability to resist a supply of hydrogen ions to the soil. Acidification has gradually increased in the O horizon in Västerbotten over a 30-year period from the 1970th to the 1990th. The aim of this study was from inventories of The Swedish National Forest Soil Survey and The Swedish National Forest Inventory explain and quantify the acidification that has occurred in the O horizon of two regions in the north of Sweden. Data from SMHI, The Swedish Meteorological and Hydrological Institute, has also been used.

The countries in the European Union have agreed to increase their percentage renewable energy sources to 20 %. To reach this goal an increase of biomass production needs to be made. One way of achieving this is by using nonnative species. Poplar in Sweden produces biomass faster than the domestic trees. In the southern parts of Sweden plantations has been made with good results. In the northern parts survival is a problem that needs to be solved before plantations can be made for commercial use.

Media affects our views of the world and plays a large part in creation and dissemination of social representations. Through media?s increasing importance, people and organizations need to work harder to stand out among the large amounts of brands that exists today.In 2013, Umea? Energi launched a commercial concept about Dolf and Ja?rven, two characters living in Lill-Grobban, a fictional village outside of Umea?. The aim of this qualitative study is to examine how Umea? Energi uses stereotypes in the commercial concept Dolf and Ja?rven and how this affects the respondents, and in the long run the stereotypification of norrlandians.

The aim of this study was to map and date glacial flutings with ice flows deviating from the predominating northwesterly ice flow direction in the southern part of Norrbotten County in Northern Sweden, and also to investigate if parts of the glacial landscape are older than previously thought. The traditional view is that most landforms in the area were formed during the late Weichselian (W3). Analysis of the new high resolution elevation model (2 m grid) derived from laser scanning was performed after treating the data with a hillshade tool in ArcMap to reveal terrain features such as flutings. The analysis resulted in a map showing four main groups of deviating ice flows (N-S, NO-SV, SO-NV and S-N) and several westerly ice flows. The majority of flutings with deviating ice flows were found in low terrain.
