26. Comparative analysis of contact and non-contact method for determining the natural frequencies of a bolted joint
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : To ensure high assembly quality of components, a proper clamping force in bolted joints is essential. The existing tightening technology rely on torque and angle; however, this thesis proposes a method for obtaining the clamping force of a bolted joint based on measuring the natural frequencies.

27. Återvinning av hårdmetallstift : En studie av hårdmetallstiftens livscykel och hur volframet i stiften återvinns
Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : I det moderna samhället finns det ett stort behov av metaller och mineraler som används i allt från mobiltelefoner till bilar. Dessa mineraler och metaller finns under marken och behöver grävas upp och genomgå förädlingsprocesser för att användas. LÄS MER
28. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

29. Investigating the effect of grinding method on ore beneficiation behaviour
Master-uppsats, Luleå tekniska universitet/Mineralteknik och metallurgiSammanfattning : Commodity projection studies anticipate an exponential increase in copper demand and decreasein mill grade of deposits currently exploited globally. Most of this demand is driven by theindispensable use of copper in electrification and currently, the growing demand in the contextof the green transition. LÄS MER
30. Religiösa uttryck i metal : En analys av religiösa uttryck i låttexter och albumomslag från två jämförelsebara musikalbum av metalcorebandet Bring Me the Horizon
Uppsats för yrkesexamina på avancerad nivå, Södertörns högskola/LärarutbildningenSammanfattning : This analysis of material from two of metal band Bring Me the Horizon’s music albums aims to investigate religious expressions and references, how the band’s view on religion can be interpreted from that, and to what extent it can be seen as expressions of the band’s religiosity. The perspective of the analysis stands in relation to theories on post secularity, and the method used is content analysis which mainly functions to interpret meaning. LÄS MER
