  1. 1. Undersökning av en ny agitationsmetod för trombocytframställning : En jämförelse mellan Trombomixer 307 och trombocytvagga (Helmer)

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

    Författare :Souha Abdoulkader; [2023]
    Nyckelord :Trombomixer 307; platelet-rocker; intreim platelet unit; platelet-concentrate; Trombomixer 307; trombocytvagga; interim platelet unit IPU ; trombocytkoncentrat.;

    Sammanfattning : Trombocyttransfusion är en viktig behandlingsmetod för att antingen förebygga eller förhindra blödning. Trombocyter för transfusion (trombocytkoncentrat) framställs med två metoder: antingen genom aferesteknik eller genom att separera helblodet i erytrocytenhet, plasma, leukocytenhet och interim platelet unit (IPU).

  3. 2. From Ocean to Table: Microplastic contamination in Nordic salts

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Anna Nyika; [2023]
    Nyckelord :Microplastic MP ; MP pollution; plastic pollution; sea salt; rock salt; Nordics; Iceland; Denmark; plastic waste management; human health; marine environment.; Earth and Environmental Sciences;

    Sammanfattning : Large amounts of plastic in the oceans originate from mismanaged plastic waste, and microplastics (MPs) are the most common type of waste. They can be found in household products, such as sea salts. Therefore, monitoring pollution levels is essential to improve marine health and food safety. LÄS MER

  4. 3. Testing aerosol vertical profiling methods with portable instruments on unmanned and manned aircraft

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Ellen Grace Soroka; [2023]
    Nyckelord :Physical Geography; Ecosystem Analysis; Aerosols; Vertical Profile; Black Carbon; PM2.5; Nanoparticles; UAV; Drone; Master degree thesis; 30 credits in Atmospheric Science Biogeochemical Cycles; Earth and Environmental Sciences;

    Sammanfattning : This thesis employed several portable sensors on board an unmanned aerial vehicle (UAV) and manned aircraft in order to test new methods of measuring vertical profiles of aerosol particles and contribute to knowledge of aerosol distributions in the atmosphere. More data in this area is required to improve atmospheric modelling and future climate scenarios. LÄS MER

  5. 4. Influence of Peristaltic Pump Tubes on Protein Particles Formation for Lipase Enzyme Therapeutic Protein

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Salah Elden Omer; [2023]
    Nyckelord :Dynamic Image analysis; Protein aggregation; Peristaltic pump tubing; Particle characterization; PVC tubing; Silicone tubing; Surfactant; QICPIC; Pharmaceutical technology; Biology and Life Sciences;

    Sammanfattning : Introduction: In Bio-pharmaceutical production, peristaltic pump tubing is considered one of the factors that influence protein aggregation. Background: Protein particles present challenges for the control and analysis of various manufacturing processes in the biopharmaceutical industry for their significant effects on safety and quality.

  7. 5. Effects of temperature and microplastic concentration on the consumption of microplastic particles by the detritivore Asellus aquaticus

    Kandidat-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Yasmin Screech; [2023]
    Nyckelord :Microplastic; Asellus aquaticus; concentration; temperature; faecal pellets;

    Sammanfattning : Microplastic (MP) pollution has now reached a point where particles can be found in every environmental compartment across the globe. However, the ecological and long-term consequences of MPs are largely unknown. LÄS MER
