1. Circular economy: : Sustainability assessment of circular business models basedon material flow analysis.
University essay from Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)Abstract : This study has contributed to the developing concepts of circular economy by assessing circular business models and to test different approaches for circularity in a measurable way. In our current era of time, we stand against environment challenges with a warming planet and resources scarcity. READ MORE

2. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. READ MORE

3. Methanobacterium cauma sp. nov., a hydrogenotrophic, halotolerant methanogen from an active serpintinization system at Chimaera seep
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : The archaeal branch of life represents some of the oldest life forms on Earth. Archaea are believed to have diverged from Prokaryotes roughly 3.5 billion years ago and it’s theorized that biological methane production started around this time as well. This would make methanogenesis one of the oldest metabolisms on our planet. READ MORE

4. Sustainable water treatment in the manufacturing industry : Investigation of the water treatment system at VCE, Hallsberg
University essay from Linköpings universitet/EnergisystemAbstract : Transitioning to circular flows is essential to economize the planet’s resources. One of the most important resources on earth is water as it is vital for all living things. However, water purification methods have proven to be very energy intensive, and increasing the circular water flows is therefore challenging. READ MORE

5. Investigating surface spring snow : Changes in the isotopic composition and conductivity along an orographic precipitation gradient in northern Fennoscandia
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Stable isotopes of oxygen (O18) and hydrogen (H2) are used as proxies of past climates when ice preserved in the polar icecaps. The main assumption when doing paleoclimatic reconstructions using these isotopes is that the isotopic composition of the snow that turned into ice reflect the present temperature of the planet during deposition.
