This thesis deals with two types of agrarian remains in relation to settlement remains; clearance cairns, low stone walls and house terraces in the area of Northeastern Uppland and the area north of Lake Mälaren, during the middle Iron Age. The aim whit this thesis is trying to get a better understanding of the relation between agrarian and settlement remains in Uppland. Three places have been chosen where these three elements are present and they are interpreted through Richard Whites concept of middle ground but also Landesque capital. The three elements have shown to be expressed in different ways in all three sites. It is possible to see two areas with different traditions, but also to see two areas that closely interact with each other, this opens up for a new discussion around agrarian remains in both areas.

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.

The goal of the society to increase the proportion of renewable energy has led to an increased demand of bioenergy e.g. forest biomass. However, there are concerns that removal of biomass will lead to decreased base cation concentrations in the soils and acidification of streams. In order to find in which types of landscape removal of branches and tops could have such negative effects, this study aims to analyse the relations between pH-sensitivity and landscape variables in the Bothnia Bay water district. GIS and digital geographical data were used to analyse the landscape in subcatchments.

I denna undersökning har jag granskat de tre tal som kung Carl XVI Gustav, ärkebiskop K.G. Hammar och statsminister Göran Persson höll till minne av flodvågskatastrofens offer, i Stadshuset den 10 januari 2005. Av de tre talen var det främst kungens som satte spår i mitt med-vetande. Kungens tal hyllades också i pressen medan de andra talarna knappt nämndes.Undersökningens övergripande syfte blev därför att försöka utröna vad det är som gör att vissa tal berör och direkt fastnar i medvetandet medan andra glöms bort. Mer specifikt studerades detta genom att likheter och olikheter lyftes fram i de tre talen och i kontexten dessa hölls i.

A great number of tourists visits each day the Fox Glacier in New Zealand and are subjected todangers such as jökulhlaups. This phenomena can occur suddenly and in a destructive way when abuilt up of water suddenly bursts and releases large amounts of water. This is well known to happen atthe near by Franz Josef Glacier which has similar settings to Fox Glacier, but sparse previous researchon the subject indicates different results of whether jökulhlaups are present or not by Fox Glacier. Thisthesis therefore aims to study the conditions for jökulhlaups at the glacier. This is done by remotesensing and field observations of the sandur in the Fox Glacier Valley, qualitative interviews andliterature studies with a comparison with Franz Josef Glacier.

This essay deals with the results and observations made during excavations in an iron age cemetery in Alsike hage, located in Alsike parish. The excavations took place in 2005 and 2006 and the investigated area comprised two adjacent, but secluded burial-constructions; a square stone setting with a secondary grave, and a stone-built terrace with at least one secondary grave. The artifacts suggests that the TPQ of the stone setting, and the construction date of the rest of the graves, is 900-950 A.D. The aim of this study was to comprehend the course of events in the investigated area, and toanalyse the archaeological finds - in comparison to the well documented an discussed material burial culture in the lake Mälar area ? in order to discuss indicators of gender and social status.Metal artefacts has been preserved as a part of the analysis..

The travelling sector is expanding worldwide, which puts all destinations under pressure to have a functioning social system and good resources to manage the problems and take advantage of the opportunities that the tourism sector can offer a community. The area around Kisumu in Kenya, like much of Africa, tourism can simultaneously ensure a stable financial future while it removes, as a result of a growing population, more and more of the scenery that many tourists want to experience. Responsible travel to natural areas that promotes conservation of the environment and improves the welfare of local people is what defines ecotourism. A concept that implies a closed cycle, where visitor?s needs are met in balance with what can be given back, without risking creating imbalances in society. Along the coast of Lake Victoria, valuable papyrus wetlands provide Kisumu vital ecosystem services such as water purification, climate adaptation while it also serves as a reservoir for biodiversity.

The European Council agreed in 2008 on a climate and energy package to combat global warming. This package is valid for each EU member country and means that greenhouse gas emissions must fall by at least 20% and the EU's energy use to 20%, consisting of Renewable Energy in 2020. The Swedish Government has set stringent climate and energy with the intention to set an example for the rest of Europe. For example, renewable energy sources account for at least 50% of energy use and our climate emissions to fall by 40% by 2020. A combination of these goals and a steadily rising oil price has led to an increased demand for wood fuel in the form of such branches and tops.

Examensarbetets mål var att utforma två förslag på ett musik- och konsthus för placering i Växjösjön. Konstruktionen ämnas vara flytande och mobil.Gemensamt undersökte författarna byggnadens förutsättningar och möjligheter, i syfte att underlätta utformningsprocessen.Författarna utformade var sitt förslag. Det resulterade i två förslag med skilda arkitektoniska särdrag, skapade utifrån gemensamt stipulerade avgränsningar.Det ena förslaget är utformat med hjälp av geometriska former med raka sidor. Det kontrasterar mot det andra förslaget som har organiska och mjuka former..

AbstractStormwater is defined as rain- and melted water. Ludvika kommun had little knowledgde about the stormwater that reaches a specific recipient Lyviken. Therefore they intended to do an research of the stormwater that leads down to Lyviken. The aim with this study was to assess the quality of the contents in the stormwater based on pH, conductivity, phosphorous, nitrogen, bacterias, oil and one sample that meassured the value of several methals. Since the population has increased for decades, the area of hard surfaces and asphalts areas also has increased. This can increase the pollutions that finally ends up in the recipient.

This thesis aims to analyse a time series containing the annual accumulation rate of minerogenic matter in the lake Kassjo?n. First there is a theoretical survey of some frequently used tools for the analysis of time series in the time domain and in the frequency domain. This survey is followed by a simulation study that illustrates how the theoretical tools work in practice. After this, the time series "toolbox" is used to analyse the time series from Kassjo?n (5701 data points).

My intention with this paper is to try to understand the meaning of the double sex symbols which can be identified on a number of Neolithic so called battle axes from the region round the lake Mälaren in Sweden. My conclusions are drawn after having studied a number of archaeological thesises. I have realized that the society was egalitarian from what is said about the funeral habits since women and men were buried with the same care. Ceramics from the Skogsmossen site show a very long continuity over 15-20 generations. These facts indicate a peaceful society without traumatic breaks where knowledge would have been lost.

ABSTRACTThe fauna of the Lower Cambrian is far from fully understood, as is the environment of that epoch. Some of the most crucial moments in the history of evolution takes place during this epoch; the Cambrian explosion and the appearance of ecosystems as we know them. That makes it an important period to investigate. Doing so, the Lower Cambrian offers a lot of problems, one of which is that body fossils are seldom preserved. That has often left us with trace fossils to create an image of the Lower Cambrian life, but also some bedrock features such as ripple marks.The main purpose of this work has been to investigate the possibilities of relating the wave lengths and forms of recent wave-generated ripples to fossil ones, and also to evaluate the methods for that kind of comparison.

The plants in the genus Elatine are characteristic for oligo and mesotrophic lakes. This study focuses on Elatine hexandra one of the four species in Sweden. It is stated as vulnerable by the National Environment Agency and a conservation plan with guidelines to preserve the plant in Sweden is under preparation. There have been a few previous studies investigating this plant in other countries but this is the first one for Sweden. The aim of this study was to investigate the distribution, growth and reproduction of E.
