The metal base was selected was Aluminium 6082 and it is reinforced with varying volume percentage of Alumina oxide and Fly ash. LÄS MER

3. 7. Evaluation of novel climate-friendly feed for Nile tilapia in Tanzania

   Master-uppsats, SLU/Dept. of Animal Nutrition and Management

   Författare :Vilma Johansson; [2023]
   Nyckelord :Black soldier fly; novel fish feed; circular aquaculture; sub-Sahara aquaculture; greenhouse gas emissions; LCA; Nile tilapia;

   Sammanfattning : Tanzania is a country located in sub-Sahara Africa by the Indian Ocean. Tanzania's aquaculture sector is small but has the potential to grow. As the population grows, so does the demand for food. Nile tilapia is the most cultured fish in Tanzania due to its hardiness, fast growth and tolerance to many environmental conditions. LÄS MER

4. 8. The Application of Multivariate Statistical Process Control during Industrial Hot Isostatic Pressing Sintering Processes : A Case study at Seco Tools AB

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Författare :Karl Ericsson; [2023]
   Nyckelord :Multivariate statistical process control; Batch processes; Quality prediction;

   Sammanfattning : This Master's thesis focuses on improving the understanding and monitoring of the Hot Isostatic Pressing (HIP) sintering process used by Seco Tools AB to manufacture cemented carbides for cutting tools. While essential for producing cutting tools with superior hardness and toughness the HIP sintering process introduces a complex relationship between the selected process parameters and the achieved materials properties.

5. 9. Evaluation of five hardwood species from Zambia to produce fuel pellets for cooking purposes : Study with a single pellet press including pellet production, post production testing and X-ray examinations

   Kandidat-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

   Författare :Annika Silvennoinen; [2023]
   Nyckelord :Pelletizing; Pellet Production; Wood Species; X-Ray examinations; Pelletisering; Pelletstillverkning; Träslag; Röntgenundersökningar;

   Sammanfattning : 81% of the population in sub-Saharan Africa relies on charcoal and firewood to cover their energy needs for cooking. In Africa charcoal is usually produced by burning tree in a traditional kilns and then the food is cooked with a carbon-fired stoves indoors. LÄS MER

7. 10. WEAR RESISTANT MULTI FUNCTIONAL POLYMER COATINGS

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Pranay Kumar Parsi; [2023]
   Nyckelord :Polymer coatings; Materials; Tribology; Wear resistant; Ice adhesion; Freezing delay; Anti-icing de-icing;

   Sammanfattning : This study aims to develop coatings which show wear resistant behaviour along with multiple functions such as improved ice adhesion, better freezing delay etc which help in improving the effectiveness of the wind turbine efficiency. The significance of anti-icing/de-icing solutions for wind turbines is emphasized since ice accretion can cause serious issues in generation of power and might lead to damage of blades. LÄS MER
