    Nyckelord :Interaktion; Normalkraft; Böjmoment; Eurokod 3;

    Sammanfattning : Below in the report, the various methods available to calculate the interaction formulas for bending moment and normal force in steel columns are examined. The standards compared are SS-EN 1993-1-1:2005 Annex A, SS-EN 1993-1-1:2005 Annex B, SS-EN 1993-1-1:2022, CEN/TS 1993-1- 101:2022 and Fpr EN 1993-1-3:2023. LÄS MER

  3. 2. The Role of Functional Traits and Trade-offs in Seasonal Succession of Phytoplankton Community Structuring : A numerical investigation of resource acquisition traits of Lake Constance

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Ayesha Nagahage; [2024]
    Nyckelord :Phytoplankton; resource acquisition; traits; trade-off; resource limitation;

    Sammanfattning : Long-term ecological research in deep lakes offers valuable insights into understanding changes in trophic states and organization of phytoplankton assemblages. Utilizing five decades of phytoplankton taxonomic trait data from pre-alpine Lake Constance, a confirmed negative relationship was found between phosphate and light affinity at the annual community trait level.

  4. 3. Creating a High-Throughput Workflow for Automated Peptide Characterization using LC-MS

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Sara Forsberg; [2023]
    Nyckelord :High-throughput analysis; Impurity profiling; UHPLC-HRMS; Peptide characterization; Peptide descriptors; Analytical chemistry; Technology and Engineering;

    Sammanfattning : In the early stage of a drug discovery project, there is a need for efficient methods that can analyse peptides in short time. This includes methods that confirm the peptide’s identity and estimates its relative purity in an efficient and reliable way. LÄS MER

  5. 4. Screening of HETP test conditions and resin storage solutions for HIC

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Analytisk farmaceutisk kemi

    Författare :Lise-Lotte Ronnerfors; [2023]
    Nyckelord :Hydrophobic Interaction Chromatography; Pfizer Health AB; Column packing;

    Sammanfattning : Hydrophobic interaction chromatography (HIC) is a common purification method for biological drug substances. For continuous monitoring the quality of the purification, a column performance test is carried out to test the packing of the resin. LÄS MER

  7. 5. Interaction for flexural column buckling : Analytical procedures compared with FE-simulations

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Noah Norberg; [2023]
    Nyckelord :;

    Sammanfattning : This master's thesis presents a study on the stability of steel structures under flexural bucklingconstraints. The study focuses on the interaction and behaviour of flexural buckling formulas in SSEN-1993-1-1 and Swedish BSK and the performance of actual structural members subjected to suchconstraints. LÄS MER
