1. Direct Sampling of the Pulsed Eddy Current Response From Non-Ferromagnetic Metals
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : The non-destructive testing method Pulsed Eddy Current, or PEC, can be used to measure the thickness and resistivity of conducting and non-ferromagnetic materials. In this project I investigated if a gauge at ABB, which uses PEC technology to measure the thickness of aluminium strips in rolling mills, can extract more information about the strip by sampling the direct signal with a higher resolution than before.

2. Evaluating abundance of deciduous trees in production forests along small stream : can Sweden meet current policy goals without intensive management
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Riparian zones are important for many ecological functions such as for providing shade to streams and leaf litter to instream organisms, as well as acting as filters for sediments and excess nutrients that are released during forestry operations. Riparian areas are also important for preservation of biodiversity. LÄS MER
3. OPEN STORMWATER SYSTEMS FOR REDUCTION OF HEAVY METALS : AN EVALUATION OF COMMONLY USED DIMENSIONING METHODS
Master-uppsats, Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggandeSammanfattning : In Östersund there are a few stormwater ponds and oil separation units connected to the stormwater network, but mostly there is no systems for filtration of stormwater before it is released into a nearby lake which acts as Östersund’s source of drinking water. In the Industrial area in Lugnvik there is an oil separation unit connected to the stormwater network but no other means of filtration. LÄS MER
4. Sequential phosphorus extraction using iron (hydr)oxide-impregnated filter paper strips
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : Phosphorus (P) is an important element for crop production. A low concentration limits crop growth whereas the residual quantity after fertilization contributes to eutrophication of surface waters. A key to success in the soil P management is its accurate estimation and potential supply to the plant. LÄS MER
5. Evaluation of Ce Addition by Different Wire inLiquid 316 Stainless Steel
Master-uppsats, KTH/MaterialvetenskapSammanfattning : It is well known that REMs are strong oxide and sulphide formers that can easily form large clusters which have harmful effect on the casting process as well as the quality of the final steel product. By adding these elements right before casting, the number of narrow transfer parts are eliminated (compared to if added in ladle) Also, the REM inclusions has less time to sinter together to form large clusters, preventing clogging.
