1. 1. Flexural strength of dental restoratives

   Master-uppsats, Umeå universitet/Institutionen för odontologi

   Författare :Mikael Blennow; Ahmed Al-Ahmed; [2023]
   Nyckelord :Flexural strength; porosity;

   Sammanfattning : Background: New dental restorative material, “Cention Forte” and “Admira Fusion” have been available on the market for quite some time but are still new in comparison with traditional resin-based composite, “Ceram.x Spectra ST” and glass ionomer cement, “GC Fuji II LC”. LÄS MER

3. 2. SURVEY OF SULPHATE-BEARING MINERALS IN LKAB'S TAILING POND

   Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

   Författare :CELESTINE IFEANYI UGWUOKE; [2023]
   Nyckelord :Tailings; Sequential extraction; Mineralogy; Sulphate;

   Sammanfattning : This research project investigated the high concentration of sulphate in a tailing pond at LKAB and the characteristics and behavior of sulphate minerals in different areas of the pond. The sampling of the tailings was carried out at Nine stationary sampling points. LÄS MER

   Nyckelord :geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

   Sammanfattning : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. LÄS MER

5. 4. Iron Pieces from The Copper Wreck : An archaeometallurgical analysis of iron bars, billets and osmund iron found in Gdansk, Poland

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Mikael Ghaysari; Benjamin Tiberghien; Maximilian Åkerblom Jonsson; [2022]
   Nyckelord :The Copper wreck; W5; Miedsiowiec; Osmund; Slag analysis; SEM; EDS; LOM; Medieval iron production; Blast furnace; Indirect reduction; Direct reduction; Kopparvraket; W5; Miedsiowiec; Osmund; Slagg; SEM; EDS; LOM; Medeltida järnproduktionen; Masugn; Indirekt reduktion; Direkt reduktion;

   Sammanfattning : The topic of osmund iron is of great interest in both historical and metallurgical perspective. Between the 14th and the 17th century osmund iron was exported extensively from Sweden but it has been difficult to characterize and confirm what exactly osmund iron is. LÄS MER

7. 5. Performance Analysis of Environmentally Adaptable Grease in Large open gears

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

   Författare :Victor Ogunmoye; [2022]
   Nyckelord :Grease; Large open gears; tribology; lubrication; wear; friction; Twin disc; Material surface;

   Sammanfattning : Environmentally adaptable grease (EAG) lubricants are essential in applications with loss lubrication due to their biodegradable nature. This is because the lubricants could be expelled into the environment during usage in some applications e.g., marine and mining applications. LÄS MER
