  1. 1. Greenhouse gas emissions from peat soil thawing in spring : a comparison between fertilized and unfertilized soil

    University essay from SLU/Dept. of Soil and Environment

    Author : Fanny Otterlin Karlsson; [2024]
    Keywords : agricultural soil; carbon dioxide; freeze-thaw cycles; nitrous oxide; soil temperature; water content;

    Abstract : Peat soils drained for agriculture and forestry contribute to a significant amount of greenhouse gas emissions. Nitrous oxide is a greenhouse gas with high warming potential and agriculture in general accounts for about 70 % of nitrous oxide emissions. READ MORE

  3. 2. Temperaturens inverkan på tillväxt av olika mikroorganismer på frysta livsmedel

    University essay from SLU/Department of Molecular Sciences

    Author : Almohannad Alahmad; [2022]
    Keywords : Frysning; ; förskämning; hållbarhet; mikroorganism; upptining;

    Abstract : Metoder för att bevara mat har varit en viktig aspekt för att säkra livsmedelsförsörjningen genom historien. Frysning och andra konserveringsmetoder har använts med framgång under årens lopp för att förlänga livsmedels hållbarhetstid, men det finns ibland mikroorganismer på livsmedel som kan växa till mängder som kan leda till sjukdom och utgöra problem för individers hälsa, eller så kan de förskämma livsmedel.

  4. 3. Developing and validating assay-ready HEK-Blue CD40L cells : For a more flexible and faster screening of Affibody® molecules

    University essay from Uppsala universitet/Institutionen för farmaceutisk biovetenskap

    Author : Erika Könberg; [2022]
    Keywords : cell biology; assay-ready cells; HEK-Blue cells;

    Abstract : Cell assay that evaluates a biologics’ potency and efficacy is an important part in the discovery and development of drug candidates. However, it requires regular maintenance of cell cultures, and the cell assays can only be performed when the cells have reached 70-80% confluency. READ MORE

  5. 4. Laboratory Investigation of Quarry Fines for Use in the Construction Industry

  6. 5. Use of a Sperm-Hyaluronan Binding Assay for evaluation of sperm quality in dromedary camels

    University essay from SLU/Dept. of Clinical Sciences

    Author : Anna Kotila-Ioannou; [2022]
    Keywords : Camel Semen; Dromedary camel; Sperm-Hyaluronan Binding Assay; sperm quality analysis;

    Abstract : The objective of this study was to assess the potential of Hyaluronan Binding Assay (HBA) to predict freezability and fertilization capacity of dromedary camel spermatozoa, and to determine if conventional sperm quality parameters and precursor of A-Kinase Anchoring Protein 4 (proAKAP4) values correlate with HBA results. Two semen samples were collected from each of six male camels. READ MORE
