   Abstract : This master thesis presents a theoretical investigation of the energy and stability of interfaces in iron-carbide compounds, specifically focusing on the α-Fe/Cr7C3 system. The study aims to fill the gap in knowledge regarding the surface energetics of these interfaces using Density Functional Theory (DFT). READ MORE

4. 13. Streamlining 3D City Modeling for Urban Flow Simulations by Automatic Integration of Multisource Topography

   University essay from Umeå universitet/Institutionen för fysik

   Author : Klara Lindroth; [2023]
   Keywords : automatic 3D city models; surface reconstruction; geometry pre-processing; CFD; OSM height attributes;

   Abstract : In the workflow of computational fluid dynamics, geometry preparation is commonly the most time-consuming step. For a fast CFD simulation, automatic surface reconstruction to obtain 3D city models for a chosen area is essential. To address this need, a literature study was conducted to map available data suitable for 3D city models. READ MORE

5. 14. Suspensions of Calcium Phosphate : Interactions of milk proteins to hydroxyapatite

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Ying Chen; [2023]
   Keywords : Calcium fortification; Milk proteins interactions; Colloid chemistry; Food technology; engineering and nutrition; Agriculture and Food Sciences;

   Abstract : Capolac is a product containing hydroxyapatite (HA) from Arla Food Ingredients, to be used for calcium fortification. The adsorption of casein and whey proteins onto the Capolac was investigated, aiming to solve the sedimentation problem of this insoluble calcium phosphate. READ MORE
