21. A Chemical Perspective on the Tellurium Source Term in the Context of Severe Nuclear Power Plant Accidents
Sammanfattning : In the event of a severe nuclear accident, one of the biggest concerns is the release of radioactive nuclides. Typically, the most volatile is likely to be released. One that is considered among the most volatile is tellurium. Additionally, health implications towards the public by tellurium can be by itself or the decay product iodine. LÄS MER
22. Long-term metal retention processes in a peat bog : Field studies, data and modelling
Sammanfattning : The study was inspired by the need to assess long-term metal retention in municipal solid waste (MSW) landfills. The long-term processes in landfills are poorly known due to the relatively short time that such landfills have been in existence. Natural analogues where similar metal binding processes could be expected were therefore sought for. LÄS MER
23. Measuring long-term effects of a school improvement initiative
Sammanfattning : There is a growing demand for studies applying quantitative methods to large-scale data sets for the purpose of evaluating the effects of educational reforms (UVK, 2010). In this thesis the statistical method, Propensity Score Analysis (PSA), is presented and explored in the evaluating context of an extensive educational initiative within science and technology education; the Science and Technology for All-program (NTA).

24. Advanced measurement and modelling methods for noise source analysis
Sammanfattning : In daily life sound is a vital dimension for the perception of the world around us but can in some cases be considered as annoying, irritating, or even harmful. In these cases the sound is labelled as noise and can be addressed in two ways, either by insulating the noise problem from the receiver (person) or by altering the source. LÄS MER
25. Source, occurrence, and fate of pharmaceuticals in natural waters
Sammanfattning : The consumption of pharmaceuticals has increased in the last few decades. After usage, pharmaceuticals are excreted via urine and feces and transported to wastewater treatment plants (WWTPs) where they are subjected to treatment processes, and finally discharged into rivers. LÄS MER
