1. 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 teknik

   Författare :Ivana Pia Saric Söderholm; Erik Readwin; [2023]
   Nyckelord :Marinduque; Metal and Metalloid; Nix Pro 2 Color Sensor; Philippines; Soil color; X-Ray Fluorescence XRF ; Filippinerna; Jordfärg; Marinduque; Metall och Metalloid; Nix Pro 2 Color Sensor; Röntgenfluorescens XRF ;

   Sammanfattning : 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.

3. 2. The chemical evolution of the Milky Way: pushing APOGEE to higher precision and accuracy

   Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Författare :Erik Fridén; [2023]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : 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

4. 3. The Psycho Mantis Effect : Redefining Immersion in Conjunction with the Fourth Wall

   Kandidat-uppsats, Uppsala universitet/Institutionen för speldesign

   Författare :Thérèse Lundqvist; Nora Ekeblad; [2023]
   Nyckelord :Diegesis; fourth wall manipulation; immersion; ludonarratology; Metal Gear Solid; NieR: Automata; the Magic Circle; video game;

   Sammanfattning : 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

5. 4. Influence of Post-treatments on Corrosion Properties of 3D printed Metal Components for Bioprocessing Applications

   Master-uppsats, KTH/Materialvetenskap

   Författare :Leyla Koort; [2023]
   Nyckelord :PBF-LB 316L; surface post-treatments; as-built; tumbling; Hirtisation; DLyte; electropolishing; chemical milling; pitting corrosion; CPT; cyclic potentiodynamic polarisation curves; immersion test in 1M NaCl and 1M NaOH;

   Sammanfattning : 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

7. 5. Pre-Straining Operation : Prediction of Strain Paths Within a Forming Limit Diagram

   Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :Elin Olofsson; Mohammed Al-Fadhli; [2022]
   Nyckelord :Forming Limit Diagram; Forming Limit Curve; Non-Linear Strain Paths; Pre-Straining; Sheet Metal Forming.;

   Sammanfattning : 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
