1. 1. Finite element density functional description of linear molecules

   University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Author : Malin Nygren; [2024]
   Keywords : ;

   Abstract : This report describes a project performed at Linnaeus University with the task of solving the Schrodinger equation for electrons in homonuclear diatomic molecules, using the finite element method in Python. The Schrodinger equation is solved for the hydrogen atom, nitrogen atom, hydrogen molecule and nitrogen molecule using a finite element method. READ MORE

3. 2. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Rasmus Staaf; [2024]
   Keywords : artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

   Abstract : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

4. 3. Behavioural response in pigs at gas stunning in foam

   University essay from SLU/Dept. of Animal Environment and Health

   Author : Madeleine Persson; [2024]
   Keywords : stunning methods; slaughter; animal welfare; carbon dioxide; high-expansion foam; nitrogen; argon;

   Abstract : There are several stunning methods used for the commercial slaughter of pigs. The two most common are electric stunning and stunning with carbon dioxide gas. It has been shown that there are several problems related to animal welfare in the stunning methods used today in commercial slaughter. READ MORE

5. 4. Exploring potential E-fuel production pathways for maritime and aviation sectors in France : a techno-economic and environmental assessment

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

   Author : Mathieu Minaud; [2024]
   Keywords : ;

   Abstract : The aviation and maritime industries pose significant challenges for decarbonization, having increased activity in the past decade. One promising solution to limit emissions in these sectors is Electrofuels (E-fuel), derived from water electrolysis hydrogen and captured CO2 or nitrogen. READ MORE

6. 5. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

   University essay from SLU/Dept. of Soil and Environment

   Author : Bella Strid; [2024]
   Keywords : nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

   Abstract : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. READ MORE
