1. Towards a Fourth Food Regime? A sustainability analysis on modern agriculture in Schwäbisch Hall, Germany
Master-uppsats, Uppsala universitet/Institutionen för arkeologi och antik historiaSammanfattning : At my thesis’s core is the transformation of the agricultural industry based on the framework of food regimes established by Philip McMichael and Harriet Friedmann. The framework of food regimes will guide the analysis of recent agricultural developments towards sustainability. LÄS MER
2. Random Edge is not faster than Random Facet on Linear Programs
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : A Linear Program is a problem where the goal is to maximize a linear function subject to a set of linear inequalities. Geometrically, this can be rephrased as finding the highest point on a polyhedron. The Simplex method is a commonly used algorithm to solve Linear Programs. LÄS MER
3. The Role of Human Rights and Agroecology at the UN Food Systems Summit : A Study of Food Security Discourse in Global Food Governance
Kandidat-uppsats, Malmö universitet/Institutionen för globala politiska studier (GPS)Sammanfattning : The UN Food Systems Summit (UNFSS), held in September 2021, brought great expectations of a sustainable food systems transition in accordance with the UN Sustainable Development Goals (SDGs). It was, however, almost instantly criticised for failing to be transparent, implementing a Human Rights Based Approach (HRBA) and agroecological principles, and for not including the UN Committee of Food Security (CFS).

4. General Relativity and Dynamical Universes
Kandidat-uppsats, Uppsala universitet/Teoretisk fysikSammanfattning : The aim of this report is to explore different models of cosmology, depending on components as matter, radiation and dark energy. To be able to investigate the behaviour and age of these model universes, it is necessary to solve the Friedmann equation. LÄS MER
5. On the Interaction Between Electromagnetic, Gravitational, and Plasma Related Perturbations on LRS Class II Spacetimes
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : In this thesis, we investigate the interaction between electromagnetic, gravitational, and plasma related perturbations on homogeneous and hypersurface orthogonal Locally Rotationally Symmetric (LRS) class II spacetimes. By using these spacetimes, which allow for the inclusion of a non-zero magnetic field, as backgrounds in a perturbative approach, we are able to see interactions between the electromagnetic and gravitational variables already to first order in the perturbations.
