11. Alkaline wet oxidation of biorefinery lignin from wheat straw
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Climate change and depletion of fossil resources have generated a need for energy production based on renewable resources such as lignocellulosic biomass. Agricultural residues, like wheat straw, is lignocellulosic biomass that could contribute to the energy supply if it was used for biogas production. LÄS MER
12. Influence of land cover changes on organic carbon and organic nitrogen concentrations in Swedish rivers
Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : There is increasing pressure on freshwater systems due to excessive nutrient loading by anthropogenic sources. In Sweden, freshwaters have become browner due to increasing exports of organic matter from soils into streams, rivers, and lakes. LÄS MER
13. From dust to a must: Investigating the social barriers to farmers’ adoption of soil conservation practices in Hungary, with recommendations for an effective information-based soil governance
Master-uppsats, Lunds universitet/Internationella miljöinstitutetSammanfattning : Soil as a fundamental, conditionally renewable natural resource is increasingly under threat from unsustainable farming practices in a changing environment. In Hungary, expansive areas of land are susceptible to soil degradation, while only a small percentage of farmers currently applies soil conservation practices (SCPs). LÄS MER
14. Anomaly Detection in User Authentication Logs using Long Short-Term Memories and Word Embeddings
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : As an increasing amount of sensitive data is being stored at various connected services and platforms, the need for robust user authentication mechanisms that maintain the users’ safety and personal integrity online are growing. Meanwhile, too strict and simplistic user authentication policies may result in a degraded user experience which increases the demand for a sharp user authentication security tool that flags login events as abnormal with high accuracy.

15. Photodegradation of macroplastics to microplastics : A laboratory study on common litter found in urban areas
Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : During the last 60 years the plastic production has increased more than 190 times and plasticpollution both at sea and land is a growing issue. Every year millions of tons of plastic waste fromland reaches the oceans, but the land-based sources are diffuse. LÄS MER
