Lack of dead wood is the main cause of decaying or loss of populations for many forest species. To increase the amount of dead wood is a prerequisite to maintain biodiversity in forests of northern Europe. In summer 2006 the recreation area Klåveröd, at Söderåsen in Skåne, Sweden, has been inventoried for high stumps (snags) of beech, (Fagus sylvatica). The result of the inventory has been compared with data of the real estate and forest management directories from the owner, region Skåne. The results have also been matched with the results from an inventory of saproxylic beetles in 2005, performed with windowtraps on selected snags both in the area and the adjacent national park Söderåsen. 594 snags were found on 747 ha.

AbstractIn my study I have investigated how a constructed outdoor green environment can beused, managed and how it works. The study also investigates the concept of socialsustainability, where, for example, civil dialogue is a method to promote this. Thisinvestigation mainly gives account for the inhabitants viewpoint but also a gardenersperspective. The study focuses on the planning process of the study object, what theoutcome has been and how the users of the green environment, think about the result. Inthe process there has been a strong concern of involving the residents and others usingthe area.

In the west part of Trelleborg, on previous farmland a new society is under construction. It is situated right next to the ocean and close to the European freeway. Eight types of villages, all with different kind of architecture will be built in the area, one of them is Torns Village built by Skanska and Ikea. A concept called BoKlok. This specific village consists of twelve houses and five apartment buildings. They are all somewhat classical in their appearance with wooden panel, but at the same time they have a modern touch.

The purpose of this study is to explore how preschool teachers succeed in their mission to conduct work that will enhance children's interest and knowledge in technology. The study was conducted by qualitative semi-structured interviews among eight teachers at seven preschools in the same municipality. The method was chosen because I wanted to get as detailed and full answers as possible. I also wanted to find out their individual perceptions. The result shows that most of the teachers think that they have insufficient knowledge to practically work with technology. At the same time they?re expressing that technology is a broad area that sometimes is a little more complicated than it needs to be.

There are records of lowering of the water level in a lot of the Swedish lakes from the middleof the 1700th century. The aim was gaining more areable land to meet the needs of more foodto support the expanding population. In areas with top soil which contents of clay or loam asin the southwest of Scania in southern Sweden this was proven to be a successful wayexpanding the total outcome of the harvest.The studied area in the northeast of Scania, though, consists of morain with a lot of mires -much less nutritious conditions. When the water level is lowered the atmosphere gets accessto the peat. The dissolving of the organic matter that has been suppressed by the lack ofoxygene below water level continues.

The concentration and storage of organic chlorine and chloride were determined in soil, to a depth of 40 cm, in a coniferous forest in the Stubbetorp catchment area in south-east Sweden. Also, the spatial distribution of the two forms of chlorine was determined. Soil samples were collected at 49 of the nodes in a grid with approximately 105 m between the nodes. The analysis of spatial variability suggested that no spatial autocorrelation was present either within the variable organic chlorine or chloride. This means that no sample was more influenced by another nearby sample, as compared to other samples further away.

This report is a thesis for collegeengineering program in structuralengineering at Uppsala University andwas commissioned by the Swedishcontractor Svevia. The study aims toprovide an overview of the mostbeneficial bridge material from bothenvironmental and economic point ofview.The life-cycle analysis covers onlycarbon dioxide emissions, since it isthe most spoken of in today?s climateagenda. Furthermore, this study aims tohighlight which parts, of the systemboundary, that contributes to greatercarbon emissions for the wood- and theconcrete bridge.The life-cycle cost analysis wascalculated with a lifespan of 40 yearsand covers the basic cost of investment,operating and maintenance, anddecommissioning costs.The analyzed constructions in this studyare existing projects that are almostcompleted. Both bridges were designed tohandle loads up to 60 tons.

By using pollen analysis and 14C-dating, the history of vegetation and land use at the old shieling place (Sw: fäbodställe) Öjingsvallen in Ängersjö parish, central Sweden, was studied. The aim of the study was to answer the following questions: 1) When was Öjingsvallen established as a shieling place? 2) What was the land use at Öjingsvallen? 3) Was the use of Öjingsvallen as a shieling place affected by the agricultural crisis in the 14th and 15th centuries? 4) Is there any relation between the establishment and land use of Öjingsvallen as a shieling place and the historically known increase in the number of shieling sites known to have taken place in the 16th and 17th centuries? 5) Was the use of Öjingsvallen as a shieling place affected by the iron production in the area? According to the study, Öjingsvallen was probably established as a shieling place during the period A.D. 300-700. The main land use at this time was forest grazing.

Today Holmen Skog finds and selects suitable thinning stands using data on upper height and basal area. These figures are often based on basic forest data that has been updated with the help of growth prediction models. The problem is that these figures are not always correct. The aim of this study was to investigate if a combination of data from a profiling laser and a digital camera for low elevation photography, can be used for collecting data on number of stems per ha, tree species mixture as well as basal area weighted mean height and upper height for stands. The possibility to use these data to assess the need for thinning cutting was also investigated.Laser data and aerial photographs were collected from a helicopter operating at an approximate height of 100 meters.

Älvkarleby, landscape character and design proposal is a Graduated Thesis (30 ECCcredtis), in the subject of landscape planning at the Swedish University of Agricultural Sciences, the Department of Rural and Urban Development. This thesis is a study and implement of the method "Landscape Character Assessment" (LCA), developed in England and Scotland as tool to analyse and highlight the landscape in different planning processes. The purpose of LCA is to increase the understanding and strengthen the role of the landscape. The thesis consists of three main parts: landscape characterization, guidelines and a design proposal. The landscape characterization emphasizes the values of the landscape in different types of planning processes, a documentation to base estimations on in any kind of change in the area. Theese estimations have resulted in guidelines that give proposals to the development of the landcape, focusing at the desingproposal.

The aim of this paper is to find an algorithm to establish and maintain a virtual enclosure around a mobile unit. The area may take any form and should be scalable up to and including national borders. The enclosure is managed on the mobile unit. The target system is Android. Smartphones, tablets and more recently, cameras is examples of mobile units. A modern mobile unit is part of a computer network.

Diversity of ground beetles (Col: Carabidae) in managed riparian grasslands. The carabid community in moist seminatural grasslands was studied at three different sites in mid-Sweden. Pitfall trapping was carried out during six weeks in spring and early summer 2003. Eight transects, each containing seven pitfall traps, were placed in three different management regimes, either late or continous grazing, or meadow. The species composition was analysed by ordination analyses, i.e. DCA and CCA.

This thesis raises the problem with acid mine drainage around the closed mine Finngruvan.The purpose of the investigation was to compare metal content in surface water in the areaand its catchments between year 2010 and 2003, also to make calculation of specific runoffand metal load, furthermore determine the recipients in the area. Surface water samplingwhere preformed at the same place as 2003 and also at a few other places of interest. Adigital elevation file were used in GIS to calculate the area of the watersheds in the region,observations in the field where also made. The collected data were used to make comparisons,calculations and conclusions. The result showed that the surface water 2010 had somewhatlower metal concentrations.

AbstractThe purpose of my study is to examine how preschool children experience nature and how the educationalists at the preschool can make nature more exciting and support the children?s personal growth. I have also studied what the educationalists of the preschool do and what they can do to make nature more interesting and playful for the children. Observations and interviews have been conducted at a preschool in a small town. The preschool is situated close to nature, that is, close to a small forested area.

The goal with this master thesis has been to evaluate and to examine the stationary resistance bridge. The resistance bridge uses a 4-point measuring to determinate the resistance, which is used in the manufacturing of the conductor. It is then used when the resistance is to be decided for coarser aluminium conductors. A conductor has to fulfil certain demands to be able to move forward in the process. One of these demands is the resistance in ohm/km, which has demands that the measure values of the resistance bridge are as true and precise as possible.
