  1. 1. PLASTER CASTS AND CORROSION AN EXPERIMENTAL STUDY ON REMOVAL OF CORROSION PRODUCTS FROM PLASTER CASTS

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Gabriella Zimmerman; [2023-11-07]
    Nyckelord :plaster cast conservation; iron corrosion staining; xanthan gel; Arbocel®; latex cleaning; chelating agents;

    Sammanfattning : Conservation of plaster casts is complex due to the nature of the material itself. Corrosion of armature and metal structural supports is one of the most common causes of damage in plaster casts and subsequent corrosion staining. LÄS MER

  3. 2. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :William Gulding; [2023]
    Nyckelord :Adsorption; D-Rainclean; metal removal; Reactive filter; stormwater treatment;

    Sammanfattning : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. LÄS MER

  4. 3. Recombinant expression and purification of sugar beet Phytoglobins in Escherichia Coli BL21 (DE3) including metabolic engineering of the heme biosynthesis

    Master-uppsats, Lunds universitet/Tillämpad biokemi; Lunds universitet/Beräkningskemi

    Författare :Pennie Lindblom; Olivia Geel; [2023]
    Nyckelord :Phytoglobin; Heme; δ-ALA; qPCR; SDS-PAGE; Bacterial cultivation; Escherichia coli; BvPgb1.2; ÄKTA; Applied biochemistry; Biology and Life Sciences;

    Sammanfattning : The protein hemoglobin (Hb) is vital for us humans to ensure enough oxygen replacement in the body. Hb-resembling proteins also exist in plants, these are called phytoglobins (Pgbs). Pgbs are very interesting since they can play a considerable role in the development of blood substitutes and iron supplements for human use. LÄS MER

  5. 4. Chip Management in Milling and Drilling of Ductile Cast Iron

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Alexander Jönsson; Giacomo Aliboni; [2023]
    Nyckelord :Chip Carryover; Chip Management; Ductile Cast Iron; Chip Removal; Chip Asportation; Milling; Drilling; Technology and Engineering;

    Sammanfattning : This paper presents a comprehensive cross-functional analysis of machining operations for ductile cast iron components in the automotive industry, focusing on the problem of chip carryover and its impact on downstream processes. The research aims to understand the role of machining and identify the source of the issue, by analyzing different machining sequences and the chips that affect the final product or subsequent production stages.

  7. 5. Vakuugradning : Utvärdering av vakuumgradning som efterbearbetningsmetod

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för ingenjörsvetenskap, matematik och ämnesdidaktik (2023-)

    Författare :Ketil Wigg; [2023]
    Nyckelord :deburrning machine; granules; deburring; burrs; Ra; surface finish; gradningsmaskin; granulat; gradning; Ra; vakuumgradning; ytjämnhet;

    Sammanfattning : En av de mest oönskade bieffekterna vid metallbearbetning är att det blidas grader. Grader kan definieras som plastiskt deformerat material som bildas på en produkts kanter och hörn. De uppstår oftast vid skär- och skjuvande operationer och kan bero på många olika faktorer. LÄS MER
