  1. 1. 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

  3. 2. Vantar av läder från det svenska örlogsskeppet Vasa 1628 : Arbete och materiell kultur i en maritim kontext

    Kandidat-uppsats, Uppsala universitet/Konstvetenskapliga institutionen

    Författare :Emil Lagerquist; [2023]
    Nyckelord :Leather mittens; early modern; marine archaeology; shipwreck; warship; Vasa; craft history; leatherwork; shoemaking; cobblers; tanners; maritime labour; material culture; sailors; 17th century; Swedish Marine; museum archaeology;

    Sammanfattning : The collections of the Vasa Museum in Stockholm Sweden not only include the world’s only complete 17th century warship, the famous Vasa who sank on her maiden voyage outside Stockholm in the summer of 1628, but also a unique and extensive collection of dress artifacts, fragments from clothes in textile and leather recovered during the excavation of the ship. This study aims to present historical narratives about the labour, knowledge of craft and everyday life of the ship’s crew by analysing leather mittens and other types of artifacts related to the work on board as material culture, aided by early modern Dutch depictions in art showing work being done on large ships contemporary with Vasa.

  4. 3. Error propagation in nuclear models

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Artis Mucenieks; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In this thesis we perform error analysis of a nuclear model based on density-functional theory developed in Lund. The Lund model allows us to perform calculations of nuclear spectra more efficiently by constructing a simple effective Hamiltonian reproducing the quadrupole deformation and pairing interaction strength parameters of a spherical Hartree-Fock reference functional.

  5. 4. Optimal peptide quantification via machine learning enhanced fragment ion ranking in DIA-MS proteomics

    Master-uppsats, Lunds universitet/Examensarbeten i bioinformatik

    Författare :Lina Lu; [2022]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : In a standard mass spectrometry workflow, acquired mass spectra are searched against a library of peptides to extract peptide spectra matches (PSMs). Peptides are normally quantified by aggregating the intensities of fragment ions extracted from MS/MS spectra. LÄS MER

  7. 5. Spectroscopic model characterisation of hot exoplanet atmospheres

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Författare :Elin Sandvik; [2022]
    Nyckelord :Transit method; Transmission spectroscopy; Exoplanets; Hot Jupiter; Modelling; Physics and Astronomy;

    Sammanfattning : Hot Jupiters are gas giants under intense stellar radiation with short orbital periods of only a few days. Due to their large radii, hot temperatures, and large scale heights, hot Jupiters can be observationally characterised in detail through spectroscopy over an entire orbital phase. LÄS MER
