1. Effects of Prolonged Electricity Supply Disruptions on Critical Entities
Master-uppsats, Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och SamhällssäkerhetSammanfattning : This study investigates Swedish critical entities (CEs) ability to maintain function during up to three months of electricity supply disruptions. It also examines possible improvement measures, and how contextual cases (grey zone, heightened state of alert, war) influence CEs’ ability to maintain function during electricity supply disruptions.

2. Analysis of a high step-up gain DC-DC converter for fuel cell and battery application
Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : In sustainable energy systems those using fuel cells, high step-up gain converters are widely used to increase the output voltage to levels that can be used by other converters, such as inverters for grid connection or powering other AC loads. In order to obtain a higher voltage gain, in comparison to a traditional boost converter, often different topologies techniques are involved. LÄS MER
3. Distributionssystem för lågtempereradfjärrvärme i framtida bostadsområden : Fallstudie för stadsomvandlingsprojektet Näringen iGävle
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljöSammanfattning : In Europe, the prices of natural gas and electricity reached an all-time high during 2022. An approach tomitigate these high prices is to expand the district heating systems in urban areas, this will reduceelectric load as well as to increase the power production in combined heat and power plants.

4. Revidering av Strålskyddshandboken hos Region Blekinge och skapande av ny hemsida för strålskyddshandbok genom att använda sig av programvaruverktyget SharePoint server.
Magister-uppsats, Umeå universitet/Institutionen för fysikSammanfattning : Background: Protecting against ionizing radiation is important, since ionizing radiation can break the DNA molecule. This in turn can cause acute injuries such as burns to the skin or cause late effects such as cancer development in the future. Radiation can be useful, but it can also be harmful to humans in wrong handling. LÄS MER
5. Spatial and temporal variability in grassland structure associated with different densities of the white rhinoceros (Ceratotherium simum) in a South African savanna
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : The direct and indirect relationships between species in different trophic levels are referred to as trophic dynamics and are important in maintaining the function of ecosystems. Megaherbivores may have effects both directly and indirectly on other species since their impact may be disproportionately large relative to their population size. LÄS MER
