1. Växtsubstrat för en hållbar stad
Kandidat-uppsats, SLU/Department of Landscape Architecture, Planning and Management (from 130101)Sammanfattning : Syftet med arbetet är att undersöka två befintliga växtsubstratsystem som används för perenner och lignoser i urbana miljöer. Detta görs i syfte med att städerna utvecklas och förtätas i en allt snabbare takt. Förtätade städer kräver fler nya och innovativa gröna lösningar för att uppnå kvalitativa resultat. LÄS MER
2. Temporal and spatial trends of heavy metal leakage from acid sulfate soils : Leakage of Ni, Zn, Cu and Fe to freshwater and marine sediments, North-eastern Sweden
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Acid Sulfate soils (AS) are recognized for being a source of acidity in freshwaters in America, Europe, Australia, and Asia. Apart from the problematic acid leachate, AS soil serves as a possible source of toxic heavy metals in freshwaters, a problem which has received far less attention than problems related to acid leachate.

3. An investigation of the interactions between clay nanoplatelets in the presence of monovalent and divalent salts, as well as cationic peptides utilising atomistic molecular dynamics
Master-uppsats, Lunds universitet/Kemiska institutionenSammanfattning : Clays are negatively charged nanoplatelets with a layered silicate structure. It has been observed from small angle X-ray scattering measurements, and coarse-grained molecular dynamics simulations (CG-MD) that clay nanoplatelets are able to form stacks, known as tactoids, in the presence of divalent or multivalent counterions [8, 5].

4. The feasibility of using macroalgae from anaerobic digestion as fertilizer in Grenada : A literature study of the potential use of residue as fertilizer in Grenada, and a complementary laboratory study to evaluate the biogas potential
Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik; KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Coastal areas in Grenada and the Caribbean are experiencing an abundance of stranded macroalgae. Climate change and eutrophication are probable causes of this inconvenience. This leads to logistic and economic dilemmas for the Caribbean societies. LÄS MER
5. Utvärdering av strategier för provtagning av förorenad mark
Magister-uppsats, Lunds universitet/Miljövetenskaplig utbildningSammanfattning : By using statistical analysis of measured data more information can be acquired about a contaminated site in comparison to using the measured data alone. This study shows that the choice of model for the distribution of the contamination is vital in getting a reliable estimation of the contaminated area. LÄS MER
