1. 1. The visibility of stellar transients in the Galactic Centre

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Astrofysik

   Author : Jonathan Ström; [2024]
   Keywords : Physics and Astronomy;

   Abstract : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. READ MORE

3. 2. Thermal Conversion of Cellulose-Lignin Precursors into Carbon Fibres

   University essay from Uppsala universitet/Nanoteknologi och funktionella material

   Author : Sofia Westberg; [2023]
   Keywords : Carbon fiber; lignin; cellulose; continuous conversion;

   Abstract : Carbon fibres are used in many applications thanks to their exceptional tensile properties in relation to their relatively low weight. These thin strands of at least 90% carbon are mixed with a matrix such as epoxy to form composites used for cars, wind turbines, prosthetics, and many other things. READ MORE

4. 3. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Ahsan Ali; [2023]
   Keywords : High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

   Abstract : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

5. 4. Energy retrofitting effect on perceived indoor climate: A case study of Estonian multi-family buildings

   University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Author : Kadri Reinumägi; [2023]
   Keywords : Indoor environment; Thermal comfort; Indoor Air Quality; Window airing habits; Energy renovation; Occupant survey; Technology and Engineering;

   Abstract : Energy renovations are an important measure for achieving the European Union’s target of climate neutrality by 2050. To meet the EU goal, Estonia needs to fully renovate 14 000 multi-family buildings by that time, affecting the indoor environment conditions of a large number of people. READ MORE

6. 5. Edible fungal biomass production using banana peel

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Jennifer Fredes Skogh; Carolina Johansson; [2023]
   Keywords : Animal feed; filamentous fungi; bio-circular economic; mycoprotein; pretreatment;

   Abstract : Banana peels account for about 61 million tons of waste each year globally. The aim of this project was to investigate the possibility of using banana peels as a substrate to cultivate edible filamentous fungi. READ MORE
