  1. 1. Artisanal Perspectives on Valsgärde : A technical analysis of scabbards

    University essay from Linnéuniversitetet/Institutionen för kulturvetenskaper (KV)

    Author : Robert Sven Guildford; [2023]
    Keywords : artisanship; crafting; interdisciplinary; Late Iron Age Scandinavia; tacit knowledge;

    Abstract : The scabbards from the Valsgärde boat-graves are fine works of artisanship, the person who made them put many hours of work into them. It is easy to get lost in typologies and books,but one must not forget that some crafts are still being practiced to this day. READ MORE

  3. 2. Facilitating Statistical Analysis for LKAB : A User-friendly Digital Tool

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Jenny Gräsvik; [2023]
    Keywords : Industrial design engineering; usability; user experience; user interface;

    Abstract : Conducting laboratory trials is crucial for the product and process development for a company active within the iron and steel industry. This is one way ensuring consistent high quality within the work and furthermore trustworthy trial results to present to internal and external clients. READ MORE

  4. 3. Material decomposition using a photon counting X-ray detector in low energy range

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Rasmus Solem; [2021]
    Keywords : Medicine and Health Sciences;

    Abstract : Material decomposition in X-ray imaging is used to separate different materials or elements in an image and to quantify their respective concentration. The material decomposition and quantification are made possible by the dependency of attenuation on the attenuating material and photon energy. READ MORE

  5. 4. Purification, functional characterization and crystallization of the PerR peroxide sensor from Saccharopolyspora erythraea

    University essay from Uppsala universitet/Strukturbiologi

    Author : Grim Elison Kalman; [2019]
    Keywords : structural biology; cell culture; protein expression; genetic engineering; spectroscopy; X-ray crystallography; small angle X-ray scattering; SAXS; transcription factor; PerR; metal binding; antibiotics; Saccharopolyspora erythraea; S. erythraea; soil bacterium; actinobacteria; actinomycetes; oxidative stress; peroxide stress; structure determination; characterization; stabilization; peroxide sensor; iron sensor; manganese sensor; metalloprotein; metal ion homeostasis; metal ion; prokaryotic; strukturbiologi; cellodling; proteinuttryck; genteknik; spektroskopi; röntgenkristallografi; småvinkel-röntgenspridning; SAXS; transkriptionsfaktor; PerR; metallbindande; antibiotika; Saccharopolyspora erythraea; S. erythraea; jordartsbakterie; Aktinobakterier; Actinobacteria; Actinomycetes; oxidativ stress; peroxid stress; strukturbestämning; karaktärisering; stabilisering; peroxidsensor; järnsensor; mangansensor; metalljonshomeostas; metalljoner; prokaryot;

    Abstract : This report summarizes the work on the cloning, expression, and purification of PerR, a metal sensing regulator from Saccharopolyspora erythraea and the subsequent characterization using small angle X-ray scattering and other biochemical methods. The report aims to provide an insight into prokaryotic metal homeostasis, provide a better understanding of how PerR works and provide valuable information for the continued work on the crystallization of PerR.

  6. 5. The Magnetic Characterization of Iron-Chrome nanoparticle

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Angga Virdian; [2018]
    Keywords : Nanomagnetism; Nanoparticle; Physics and Astronomy;

    Abstract : In this thesis, the intrinsic magnetic characteristic of 10 nm FeCr oxide nanoparticles is studied. The nanoparticles is produced using the method of Spark discharge generation. Scanning electron microscope (SEM) is used to characterize the size distribution and coverage of deposited particle. READ MORE
