1. Power Reconstruction Uncertainties in European Pressurized Reactor Impact of Partial. Unavailability of Sensors
Master-uppsats, KTH/FysikSammanfattning : This study is part of a theme related to the physical tests performed on the core of nuclear reactors and particularly the EPR, a new French reactor under construction on the Flamanville site. The peaking factors of this reactor are continuously monitored by an instrumentation located both inside (collectrons) and outside (external fission chambers) the core. LÄS MER
2. Methane and Carbon Dioxide Emissions From Three Smallscale Hydropower Stations in South of Sweden
M1-uppsats, Linköpings universitet/Tema MiljöförändringSammanfattning : Over the past decades, evidence show that the anthropogenetic greenhouse gases (GHG) emissions of carbon dioxide (CO₂) and methane (CH₄) are the main drivers behind global warming and are becoming stronger. Globally, hydropower is among the main sources of renewable energy and the popular notion that hydropower electricity is carbon neutral has been under debate as evidence from measurements in different regions of the globe show significant and highly variable carbon emissions from hydropower reservoirs.

3. Greenhouse gas emissions from three large lakes during the autumn 2020
Kandidat-uppsats, Linköpings universitet/Institutionen för temaSammanfattning : Methane (CH4) and carbon dioxide (CO2) are two greenhouse gases and main drivers of global climate change. Lakes are known to be a source of CH4 and CO2 to the atmosphere. While the importance of these emissions is clear, their magnitudes and regulation are still uncertain due to the scarcity of flux measurement data from lakes. LÄS MER
4. Variability of summer CH4 and CO2 flux rates in and between three large Swedish lakes : A spatio-temporal field study
Kandidat-uppsats, Linköpings universitet/Tema MiljöförändringSammanfattning : Understanding of natural greenhouse gas (GHG) cycles is crucial for making GHG budgets, which work as basis in climate change and global warming policy programs. Lakes as a source for GHG activity have only recently been included in global GHG budgets, and most studies of lake GHG flux rates are conducted on lakes <10 km2, which only comprise roughly half of the global lake area—making data of large lake flux rates scarce.

5. Stora sjöars metanutsläpp till atmosfären : En studie på tre svenska sjöars rumsliga variation av diffusion och ebullition
Kandidat-uppsats, Linköpings universitet/Institutionen för temaSammanfattning : Sedan förindustriell tid har atmosfärens metankoncentration ökat med 150 % vilket bidragit och fortsätter att bidra till en global medeltemperaturökning. En stor andel av metanet släpps ut från sjöar, detta trots att sjöar utgör en liten del av jordens yta. LÄS MER
