1. Åtgärder mot förhöjda halter av per- och polyfluorerade alkylsubstanser (PFAS) i dagvatten : Styrande mål och riktvärden
Uppsats för yrkesexamina på avancerad nivå,Sammanfattning : Stormwater is a significant transport medium for pollutants to recipients located near cities. Substances commonly found in stormwater include nutrients, metals, organic substances and particles. A group of pollutants detected in stormwater are per- och polyfluoroalkyl substances (PFAS).

2. Trädplantering i den hårdgjorda staden : utmaningar och lösningsalternativ
Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)Sammanfattning : Träd är viktiga delar av våra städer. De bidrar med många ekosystemtjänster, som klimatreglering, dagvattenhantering och positiva hälsoeffekter. De är också viktiga identitetsskapande element. LÄS MER
3. Hormonal Influence on the Proliferation Potential of C17.2 Neuronal Progenitor Cells
Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : The brain is arguably the most complex organ of the body: Controlling muscles, maintaining homeostasis, processing information. It has the longest developmental period of any organ, and hormones are essential during its development. LÄS MER
4. Techno-Economic Analysis of Dye Separation in Textile Recycling
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. LÄS MER
5. Microbial production of chemical building blocks from lignin
Master-uppsats, Lunds universitet/Teknisk mikrobiologiSammanfattning : Plastics, derived from fossil fuels, have raised considerable environmental concerns. This has prompted the search for sustainable and safer plastic precursors alternatives. One alternative explored in the present study is vanillin, a phenolic compound derived from lignin, an abundant and renewable natural polymer. LÄS MER
