The field trial Exploatering av höga P-AL-tal (Exploiting P in heavily P dressed soils) started in 1982-1983 and included seventeen study sites placed across Sweden. Each site included three treatments, one unfertilized control (A), one aiming at replenishment of harvest removal, i.e. fertilized with 15 kg P ha-1 year-1 (B) and one over-fertilized (C) with 30 kg P ha-1 year-1. In this thesis data from the five longestrunning study sites are analysed based on four hypotheses. The hypotheses stated that in soils with high P-AL values and a pH over 6.0 P-AL will not decrease over time in the control (A) or in the replenishment treatment (B), that P-AL and P-HCl in the top soil will increase at all sites for the over-fertilized treatment (C) and that yields will not decrease as long as the P-AL is above 12 mg P 100 g-1 soil. My conclusions from the analysis of data from the selected sites are as follows: - A pH above 6.0 cannot guarantee a stable P-AL value in an unfertilized but phosphorus-rich soil. - The P-AL of unfertilized soils decreased faster at lower soil pH than at higher pH. - In the replenishment treatment (B) the rate of P-AL decrease seems to fall at a pH of 6.5. However, the influence of the soil type cannot be ignored. - P-AL and P-HCl did not increase in all over-fertilized treatments.

Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements,  used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.

This paper examines and compares several different sites in Sweden in addition to one in Mexico regarding whether the ecological requirements theses sites have had during planning and construction has affected the design in any way. Is it possible that, for different reasons, one thinks ?like nature? when one thinks of ecology and, if true, how does this reflect on the spatial and structural design? This paper tries to identify if some sort of general design expression is used in projects with requirements on ecological sustainability. In total, five projects have been compared in different areas such as choice of materials and their composition. These projects have an ecologically sustainable processing of water in common, although most also have ecological consideration in other areas as well.

The connection between rune stones and churches is a known phenomenon. Unfortunately, very little is known about the previous function of the church sites, and consequently very little is known about what the connection between rune stones and churches means. The purpose of this study is to examine the rune stones connected to churches in the administrative province of Jönköping, in an effort to ascertain their purpose, symbolism and function. The aim is to find out if the rune stones connected to churches were primarily or secondarily placed on the site where the church was later built, and why some rune stones were built into the churches. Further, the inscriptions and iconography of rune stones have been analysed, and also their relation to their immediate surroundings.

This paper deals with the early mesolithic sites in Gladö, a part of Hanveden situated south of Stockholm. It tries to explain the big amount of sites, why people came to these islands and what they were doing there. The large shore displacement together with the topography of the mesolithic islands resulted in a rapid change of suitible areas for camping. The prime occupation was sealhunting on the ice of the Ancylus lake in early spring. As the archipelago became larger other activities as fishing and birdhunting got more important and people stayed for longer periods..

The thick shelled river mussel (Unio crassus) has a fragmented distribution in southern Sweden. It is a threatened and protected species. In both the Swedish red list and the IUCN Red List of Threatened Species Unio crassus is classified as Endangered (EN). Causes for this classification are for instance differentiated bottom substrate and deterioration in water quality. In this study, habitat preferences of Unio crassus were investigated to assist in future restoration work.

The county administration asked LKAB to make an inventory of possibly contaminated sites caused by their mining activity. The inventory should be performed according to the MIFO model, a method from SEPA which is used to assess a contaminated site. The first phase involves collection of information through interviews and site inspections and in phase 2 a general survey with field sampling is conducted. LKAB started the work with the first phase of the survey during 2003. During this project the information collected in Phase 1 was evaluated and 16 of the sites were chosen to proceed to MIFO Phase 2 (six sites in Kiruna, and 5 sites respectively in Svappavaara and Malmberget). The sampling of these 16 sites was performed during week 27 2004.

There is a need for examining the accessibility of public web sites and for several reasons. First, public organizations possess considerable amounts information of interest to its citizens and which ought to be easily accessible. Secondly, international and national guidelines for web publishing support the different types of requirements experienced by web users and, in particular, with regard to accessibility for people with disabilities. The thesis examines the design of public Web sites from two different aspects. Web sites can be built up and structured from the management view of the public organization, or, they can be constructed with a view to user needs and requirements.

This essay is about two areas called Hackås and Myrviken, situated in the middle of Sweden around the lake Storsjön. In Hackås we can see traces after an early agrarian settlement, and in Myrviken we find Jämtlands largest concentration of ironmaking sites from around 400 AD. There are no clear evidence of the agrarian settlement in Myrviken, and only two ironmaking sites in Hackås. These two economies functioned at the same time, but were clearly separated. My purpose is to discuss if it was the farmers of Hackås who made iron in Myrviken, or if it was somebody else..

A new site- and construction-law came into effect in May 2011. The new law, PBL2010:900 implies several different changes of the law. These changes concern bothconstructors, people working in municipality and county councils and other peoplethat in some way are related to the building sector. Except from the change in orderof the chapters and the renewed and modernized language, the law has now beenextended with a few new phases.According to the new law a certificate has to be issued to start and finish theconstruction; the construction consulting has changed name into technical consultingand the protocol for the controls has to show what the control is being compared to.This diploma work concerns control visits on construction sites as related to the newlaw. The reason why visits on construction sites are now implemented in the law isbecause the government saw a lack of trustworthiness in the old law.

Inventories of epiphytic lichens on Scots pine (Pinus sylvestris) were conducted at three sites in east central Sweden: along the newly build motorway (Road E4), along the old road (Road 600) and in a reference site, to compare the effects of traffic pollution on lichen diversities. At each site, species richness, lichen mean sensitivity value (MK), air quality index of the forest stand/sample plot (LKI) and nitrogen impact value (N) were calculated and it was tested if there was any difference between the sites. Twenty-four species were observed in total, and Parmeliopsis ambigua and Hypogymnia physodes were the most common species at all sites. At Road E4, fewer lichen species were observed than at the other sites and this might be due to the impact of air pollution. The species richness at Road 600 was similar to that of the reference site, which might be explained by the improved air quality.

This thesis analyses the decoration on the pots of the Pitted Ware Culture on Gotland. The pottery from this period is richly decorated with various ornaments, the most common are the pits but other types of decoration occur. The purpose of this study is to get an insight into what the patterns meant to the people that made and used them and what role these may have played in their lives. The author will analyse the decoration on potsherds found from the three Pitted Ware sites of Visby, Ajvide and Hemmor on Gotland. This will be used in a comparative analysis to investigate if differences and/or similarities of the pattern occur between and among the sites.

The snow leopard (Panthera uncia) is an elusive felid, native to the mountains in central Asia. Basic knowledge about the snow leopards? ecology has long been lacking but is advancing with the help of the GPS-technology. GPS cluster analysis can provide insight in the diet and prey selection of elusive predators, such as the snow leopard. Acceleration data from GPS collars can be used to study animal behavior but the two have never been combined to gain more detailed information of the feeding behavior of large carnivores.
