41. Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes. LÄS MER
42. Spent Nuclear Fuel under Repository Conditions : Update and Expansion of Database and Development of Machine Learning Models
Master-uppsats, KTH/KemiSammanfattning : Förbrukat kärnbränsle är mycket radioaktivt och behöver därför lagras i djupa geologiska förvar i tusentals år innan det säkert kan återföras till naturen. På grund av de långa lagringsperioderna görs säkerhetsanalyser av de djupa geologiska förvaren. LÄS MER
43. Utvärdering av metod för beräkning av teoretiska sprickvidder för bestämning av tätningsresultat
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : When constructing a tunnel, the main challenges are geotechnical and hydrogeological. In the working process the aim in tunneling is to secure the rock mass by sealing the mass before blasting. This is done by grouting. LÄS MER
44. Electrochemical oxidation of PFAS in soil conditions : Using Boron-doped diamond electrodes and iron electrodes
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Per- and polyfluoroalkyl substances (PFAS) are a rising topic in the field of contaminated sites around the world, with destruction of these being an area in dire need of innovation. Previous experiments of destructive character have been proven efficient using boron doped diamond electrodes (BDD) in small scale electrochemical cells. LÄS MER
45. Forecast-based AI Decisions for Winter Road Maintenance
Master-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : In countries with freezing temperatures, proper road maintenance is an important intervention to reduce traffic accidents and fatalities and improves road passability. While de-icing using road salt can be an effective intervention, it may also lead to harmful side effects such as damage to vehicles, groundwater contamination and plant stress. LÄS MER
