    Sammanfattning : I dagens samhälle finns alla möjliga sorters sjukdomar - alltifrån den vanliga säsongsinfluensan till mer allvarliga infektioner och kroniska sjukdomar som cancer och Alzheimers. Därför finns även ett stort intresse för att kunna ställa rätt diagnos samt söka möjliga behandlingar och att bota dessa sjukdomar. LÄS MER

  3. 22. Surviving ratio of milk microflora during storage at freezing temperature : a pilot study

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Louise Gustafsson; [2022]
    Nyckelord :Raw cow´s milk; raw milk quality; milk microflora; culturing methods; MALDI-TOF MS; cold storage of milk;

    Sammanfattning : Milk contains beneficial and non-beneficial bacteria which contribute with different outcomes to milk and dairy products. Beneficial bacteria are important during manufacturing while non-beneficial bacteria cause spoilage, food related outbreaks but also economical losses for the dairy industry. LÄS MER

  4. 23. Accelerator-Based Analysis of Rough Wall Materials From Fusion Devices

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

    Författare :Fabian Persson Djurhed; Vilhelm Forkman; [2022]
    Nyckelord :Potku; TRIM; SIMNRA; ToF-ERDA; Roughness; Simulations;

    Sammanfattning : Time of Flight - Elastic recoil detection analysis (ToF-ERDA) is a method used to analyse the composition of wall samples from fusion devices. All current analysing software for ToF-ERDA assumes that the target is perfectly flat which could create inaccuracies when rough surfaces are analysed. LÄS MER

  5. 24. Bacterial contamination on pork necks and loins

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Henrik Johansson; [2022]
    Nyckelord :Pork meat; Pork loins; Pork necks; chops; food safety; food control; contamination;

    Sammanfattning : The aim of the study was to investigate if there is a difference in the quantity of bacteria that could affect the shelf life of pork loins and pork necks. Samples from pork loins and pork necks from a cutting plant was analysed during three occasions during three weeks. LÄS MER

  7. 25. Screening for carbapenemase-associated biomarkers in Klebsiella oxytoca using matrixassisted laser desorption/ionization time of flight mass spectrom

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Hannah Uppström; [2022]
    Nyckelord :MALDI-TOF MS; carbapenems; Verona integron-encoded metallo-β-lactamase; carbapenem resistance; AST biomarkers;

    Sammanfattning : Antibiotic resistant bacteria are threatening human health, and the resistance is progressingfaster than the development of new antimicrobial compounds. Antibiotic resistant infections cost enormous sums of money and resources, but most importantly human lives. LÄS MER
