… the capacity of this system is limited, therefore LKAB wants to expand the surface of the sedimentationbasin by moving one of the basin walls further out in to the nearby lake, Naalojärvi. A lake investigation has been preformed, with focus on parameters important for lake …

… measures. The condition of this section was most likely due to erosion from surface runoff and from bank failure. This was probably caused by unsatisfactory dimensions for today’s larger precipitation. A clean out is recommended as well as starting to use protection zones on the …
… technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation …
Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and …
… when the ground becomes saturated, phosphorus leakage could be seen in surface runoff or in point sources resulting from inadequate manure storage management. In the municipality of Växjö there is still many bodies of water that do not reach the Swedish environmental water …
ett gis-baserat försök med dtw-index och laserskannad övre höjd
… elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed …
… from dead algae, which is stimulating sulphate reducing bacteria, at the surface. As a result, Hg is transformed to MeHg. This conclusion was supported by incubation experiments, verifying that the methylation rates were highest in the top 0-5 cm sediment layer. The solubility …
… with hot water and whose only possibility to release heat is to the floor surface. By studying the temperature decrease process you can determine the thermal resistance of different floors without knowledge of the floor insulation, thickness of the concrete and the surface …
… fill material consists mainly of sand that becomes finer below the groundwater surface at the depth of about 2.3 m. Above the groundwater surface pyrite cinders was encountered. Underneath the cinders, lime sludge, bark and wood fiber were found at different depths. The deepest …
… However, that causes phosphorus leaching from arable land to surrounding surface waters and lakes and contributes to the eutrofication. There are three types of soils in Sweden that are at higher risk of contributing to phosphorus leakage. There are clay soils with an extended …
metodutveckling med GIS
… (GIS) to identify areas with risk for phosphorus losses due to surfacerunoff. This tool can act as a decision support to decide where appropriatemeasures should be applied with the aim of reducing phosphorus losses and bythat the eutrophication.The method that has been used is a …
… and additives) and persistent organic pollutants (POPs) gathered on their surface. The latter because micro plastics have a large hydrophobic surface, which accumulate POPs to a great extent, leading to up to 105-106 times more POPs on micro plastics than in the surrounding …
… post-treatment methods examined are soaking the objects in deionized water and surface rinsing with deionized water. The comparative analysis included photographs under normal and UV-light exposure to assess stain visibility, weight measurements before and after treatments to …
… part goes to the diffuse sinks where the de-icing fluids degrade on the soil surface or percolate into the soil. In the case study there is also an investigation of the probable impacts on the surrounding environment due to aircraft de-icing at Stockholm-Bromma Airport and …
… clay and talc. Thequestion remains how these material bond to the blanket surface. The chalk and clay comes from thepaper. The talc comes from the ink. Deposits from image areas contain pigment and talc from the printingink. The dampening water has also been analyzed. The result …
