  1. 16. Vaccin mot SARS-CoV-2 – en utvärdering av effektivitet och säkerhet av ledande vaccin : En Litteraturstudie

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Sean Wrywood; [2021]
    Nyckelord :SARS-CoV-2; Covid-19; Vaccin; BNT162b2; mRNA-1273; AZD1222; ChAdOx nCoV-19; AD26.COV2.S; Pfizer BioNTech; Moderna; AstraZeneca; Johnson Johnson;

    Sammanfattning : Introduktion: Coronavirus är RNA-virus med ett lipidhölje som är täckt utav karaktäristiska spikprotein. De mest kända coronavirusvarianterna är SARS-CoV-1 som var aktiv mellan 2002-2004, MERS-CoV som har varit aktiv sedan 2012 och SARS-CoV-2 som har varit aktiv sedan 2019–tillsvidare. LÄS MER

  3. 17. Influence of different colormaps on the perceptual interpretation of numerical values produced by a self-organizing feature map

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Gabriel Ulander Voltaire; [2021]
    Nyckelord :;

    Sammanfattning : To visualize important information and generating a well suited colormap to represent the features of interest in a dataset is complicated. Some colormaps provide with less accurate insights of the data. Meanwhile other colormaps can provide effectively a stronger understanding and identifcation of features in the data. LÄS MER

  4. 18. Electrically powered manoeuvring of water jets

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Joel Engström; [2021]
    Nyckelord :Bachelor thesis; Thesis; Mechanical engineering; Uppsala University; Design; Product development; Marine Propulsion; Electrical Actuator; Water Jets; Water Jet Propulsion; Water Jet Manouvering; Steer-by-wire; Marine Technology; Examensarbete; Maskinteknik; Kandidatuppsats; Uppsala Universitet; Konstruktion; Design; Produktutveckling; Vattenjet; vattenjetaggregat; Elektrisk Manövrering; Steer-by-wire; Marinteknik;

    Sammanfattning : A shift towards electric and hybrid propulsion within the marine sector create new challenges for conventional water jet units manoeuvred by hydraulic systems. The high efficiency in high speed water jet crafts benefit from being powered by electricity but will be compromised by constantly running hydraulic pumps, draining available electric capacity on-board.

    Sammanfattning : It is inevitable that Structures become older and their intended use changes or the structuralcodes regulations change. In some regions the damage from seismic activities is a possibility.It becomes, therefore crucial to assess the structural capacity of such structures. LÄS MER

  7. 20. Aroma components of long ripened cheese and their origin, variation and contribution to flavour : with focus on propionic acid

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Sandra Carlsson; [2021]
    Nyckelord :cheese ripening; aroma components; volatile compounds; metabolism of lactose; lactate and citrate; ; proteolysis; lipolysis; propionic acid bacteria; sensory evaluation;

    Sammanfattning : Flavour compounds in cheese are formed by metabolism of residual lactose, lactate and citrate, proteolysis and lipolysis through the activity of e.g., starter bacteria. Generally identified aroma components in cheese are fatty acids, esters, alcohols, ketones, lactones, aldehydes, and sulphur compounds. LÄS MER
