  1. 1. Method Development for Evaluating Pitch Dispersing Agents Used in the Kraft Pulping Process

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Emma Olsson Månsson; [2020]
    Nyckelord :pitch deposit; dispersing agent evaluation; method development; calcium soaps;

    Sammanfattning : Depending on wood species and the extractives of the wood, the paper and pulp processes might suffer from problems caused by the formation of pitch deposits from calcium soaps. BIM Kemi is a specialty chemical producer supplying the pulp and paper industry with dispersing agents, which prevent these problems. LÄS MER

  3. 2. Fragment-screening by X-ray crystallography of human vaccinia related kinase 1

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Yousif Ali Rashid Majid; [2020]
    Nyckelord :Fragment based drug discovery; X-ray crystallography; screening; vaccinia related kinase 1; crystal optimization; fragment library design; differential scanning fluorimetry; Sprint Bioscience;

    Sammanfattning : Fragment-screening by X-ray crystallography (XFS) is an expensive and low throughput fragment drug discovery screening method, and it requires a lot of optimization for each protein target. The advantages with this screening method are that it is very sensitive, it directly gives the three-dimensional structure of the protein-fragment complexes, and false positives are rarely obtained.

  4. 3. The effect of the shoe sole on Plantar Pressure distribution

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Geraldine Ejimadu; [2020]
    Nyckelord :Peak Plantar Pressure; PP; pressure distribution; Diabetic Foot Ulcer; DFU;

    Sammanfattning : Patients affected by Diabetes Mellitus have reduced tactile sensitivity and atrophy of the small muscles in the foot, resulting in high-pressure points that may remain unnoticed. The increased pressure can cause micro-trauma leading to wounds. Because of the Diabetes Mellitus, DFUs do not heal easily. LÄS MER

  5. 4. Pulverkol som akut kemisk barriär för dricksvatten

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Alexandra Klerck; [2020]
    Nyckelord :Bensin; MGO; Hybridolja; Pulveriserat aktivt kol PAK ; oljeutsläpp; löslighet;

    Sammanfattning : På Norrvattens reningsverk, Görvälnverket, produceras dricksvatten genom rening av råvatten från Östra Mälaren. Dricksvattenverket ligger i direkt anslutning till Mälaren, vilket är bra då vattnet inte behöver transporteras för att renas. LÄS MER

  7. 5. Archaeologic inspection of the Milky Way using vibrations of a fossil : Seismic, spectroscopic and kinematic characterization of a binary metal-poor Halo star

    Kandidat-uppsats, Uppsala universitet/Observationell astrofysik

    Författare :Amanda Byström; [2020]
    Nyckelord :Milky Way; Halo; galactic archaeology; asteroseismology; binary star; CEMP stars; CEMP-r s stars; stellar age; stellar mass; chemical abundance pattern; Gaia-Enceladus; Gaia-Sausage; Sequoia; spectroscopy; metal-poor;

    Sammanfattning : The Milky Way has undergone several mergers with other galaxies during its lifetime. The mergers have been identified via stellar debris in the Halo of the Milky Way. The practice of mapping these mergers is called galactic archaeology. To perform this archaeologic inspection, three stellar features must be mapped: chemistry, kinematics and age. LÄS MER
