1. Investigating the potential correlations between metal and metalloid concentrations and soil color : A Minor Field Study on the island province of Marinduque, Philippines
Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : This study was carried out as a bachelor's thesis at KTH Royal Institute of Technology during the spring of 2023, investigating the correlation between the color with the concentration of various metal and metalloids (MMs) in the soil of Marinduque, The Philippines. With a history of mineral exploitation, notably copper and gold, the island has faced persistent environmental challenges, exemplified by the catastrophic waste spills in 1993 and 1996 that contaminated the Boac and Mogpog Rivers.

2. The chemical evolution of the Milky Way: pushing APOGEE to higher precision and accuracy
Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : In the recent decade, a rapid increase in all-sky spectroscopic surveys has occurred, and with it, the wealth of observational data and information on our Galaxy. Consequently, numerous detections of new structures, such as new open clusters, accreted and in-situ components, are discovered. LÄS MER
3. The Psycho Mantis Effect : Redefining Immersion in Conjunction with the Fourth Wall
Kandidat-uppsats, Uppsala universitet/Institutionen för speldesignSammanfattning : This thesis broadens the discussion surrounding the fourth wall and immersion in games; the hypothesis being that there are more ways to manipulate the fourth wall other than breaking it, and that manipulation of the fourth wall does not necessarily break immersion. Four types of fourth wall manipulation have been labeled in this body of work: breaking, expansion, contraction, and grazing. LÄS MER
4. Influence of Post-treatments on Corrosion Properties of 3D printed Metal Components for Bioprocessing Applications
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Additive manufacturing (AM) has the potential to overtake the conventional production of pipe systems of stainless steel grade 316L intended for bioprocessing applications by utilising powder bed fusion laser beam (PBF-LB) technologies. However, challenges such as high surface roughness need to be overcome and corrosion properties improved to meet industry standards. LÄS MER
5. Pre-Straining Operation : Prediction of Strain Paths Within a Forming Limit Diagram
Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknikSammanfattning : In a Sheet Metal Forming (SMF) operation, complex geometries in multi-stage forming processes are mostly common. Forming a blank, major and minor straining willoccur. Follow the straining of the blank elements over the forming process will provide its strain paths. LÄS MER
