1. 6. Global Warming Induced by Oceanic Anoxic Event 1a Had a Pronounced Impact on the Early Cretaceous Terrestrial Vegetation of Southern Sweden

   University essay from Uppsala universitet/Paleobiologi

   Author : Marcos Amores; [2022]
   Keywords : palynology; spore-pollen; biostratigraphy; oceanic anoxic event 1a; high-latitude; Early Cretaceous;

   Abstract : The Mesozoic is punctuated by several rapid global warming events that are marked by the worldwide deposition of organic-rich marine sediments. These events, known as oceanic anoxic events (OAEs), are characterised by intervals where the worldwide carbon cycle suffers a disruption due to major palaeoceanographic and climatic shifts, leading to anoxic marine environments and the creation of black shales.

3. 7. Electrochemical Behavior of the High Entropy Oxide (Mg,Co,Ni,Zn)1-xLixO (x=0,35)

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Rasmus Sandström Kinnane; [2022]
   Keywords : high entropy oxides; lithium-ion battery; x-ray diffraction; scanning electron microscopy; cyclic voltammetry;

   Abstract : Today's society is currently developing lithium-ion batteries to eventually replace the use of fossil fuels. High entropy oxides is a new type of material to use as an anode in the lithium-ion battery. These high entropy oxides may consist of a few different transition metals including lithium and oxygen.

4. 8. Alternative fuels for Swedish short sea shipping and inland waterways: Techno-economic study

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Julien Maszelin; [2022]
   Keywords : Alternative fuels Comparison Short sea shipping Inland waterways Sweden Biofuels Fischer-Tropsch Methanol Hydrogen Ammonia Fossil fuels Sustainable transportation;

   Abstract : Climate change is raising huge challenges for all industries worldwide. It is mainly due to anthropogenic activity and energy consumption which is the cause for emissions of greenhouse gas (GHG) among other environmental impacts and is expected to have huge impact on our societies globally.

5. 9. Measuring the [C II]-to-H I connection in high-redshift absorption-selected galaxies

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Gaurav Senthil Kumar; [2022]
   Keywords : QSO; Quasar; Black Hole; AGN; Active Galactic Nuclei; DLA; Damped Lyman Alpha; C II; [C II]; H I; Sightline; HST; X-shooter; Spectroscopy; Echelle Spectroscope; Hyperfine transition; Hyperfine; Physics and Astronomy;

   Abstract : HI neutral gas is the basic building block of galaxies. It dictates the star formation rate and hence the metal enrichment rates within high redshift galaxies. HI neutral gas cannot be directly observed beyond z ≈ 0. READ MORE

6. 10. Exploring improvements of wind power forecasts using Convolutional Neural Networks and Time Series Analysis

   University essay from Lunds universitet/Matematisk statistik

   Author : Jakob Nabialek; [2022]
   Keywords : wind power forecasting; convolutional neural networks; kalman filter; electricity market; day-ahead market; Mathematics and Statistics;

   Abstract : Due to environmental considerations, volumes of renewable power production are rapidly growing, and its share of the energy pool is increasing. The inter- mittent nature of wind power, being one of the main renewable energy sources, is a challenge when generating production forecasts. READ MORE
