  1. 21. Design and Modelling of a Container for Optimal Flow Rate and Wastewater Purification

    University essay from Umeå universitet/Institutionen för fysik

    Author : Olle Stenlund; [2021]
    Keywords : CFD Simulation; Design; Construction; Pumping System; Water purification;

    Abstract :   Industries are becoming more aware of how they use water in their production process. In many cases, they release wastewater back into the water supply untreated, which can cause adverse side effects to the ecosystem. A sustainable environment requires efficient water purification. One approach to purify wastewater uses rotating bed reactors. READ MORE

  3. 22. Evaluation of Wet Spinning of Fungal and Shellfish Chitosan for Medical Applications

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

    Author : Ghasem Mohammadkhani; [2021]
    Keywords : Chitosan fiber; Fungal fiber; Wet spinning; Hydrogel; Suture applications;

    Abstract : The aim of this project was to address the food waste problem, particularly bread waste, to some extent by producing monofilaments obtained from wet spinning of fungal hydrogel through the cultivation of Rhizopus delemar on bread waste. The project had two phases. READ MORE

  4. 23. Superradiant axion clouds and their interaction with astrophysical plasma

    University essay from KTH/Fysik

    Author : Erik Engstedt; [2021]
    Keywords : axions; superradiance; black holes; black hole accretion; astrophysical plasma; axioner; strålningsförstärkning; svarta hål; svart hålansamling; astrofysikalisk plasma;

    Abstract : Axions are one of the best-motivated particles beyond the standard model of particle physics and a promising candidate for dark matter. Through the superradiant instability, axions can extract a significant amount of rotational energy from spinning black holes resulting in dense axion clouds. READ MORE

  5. 24. Fibres from Reindeer Tendons : Mechanical and retting processes for extractning collagen fibres

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

    Author : Alice Lindh; Pontus Blomberg; [2021]
    Keywords : reindeer; extraction; fibre; fibre extraction; collagen; collagen fibre; reindeer thread; yarn; epitenon; endotenon; slaughter; waste; ánjis; čeavžesuotna; craft;

    Abstract : Collagen fibres from reindeer tendons can be used to create threads. These threads have traditionally been used in Sápmi crafts. Due to the high cost of manual extraction, tendon-based threads have been replaced with cheaper synthetic threads. READ MORE
