  1. 11. A Molecular Dynamics Simulation Study of the Protein Stability of Reteplase in Formulation with Various Excipients during Freeze-Drying Processing

    University essay from Lunds universitet/Biofysikalisk kemi

    Author : Gabriella Björkengren; [2021]
    Keywords : Biophysical chemistry; protein stability; molecular dynamics simulation; Chemistry;

    Abstract : The purpose of this project was to investigate protein stabilization by formulation excipients during the process of freeze-drying using Molecular Dynamics (MD) simulation. A recombinant therapeutic protein, Reteplase, was used as a model and the study focused on a comparative analysis of two excipients, arginine and tranexamic acid (TXA), as included in commercially available formulations of Reteplase.

  3. 12. Unsupervised Feature Extraction from CT Images for Clustering of Geological Drill Core Samples

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Miquel Sven Larsson Corominas; [2019]
    Keywords : ;

    Abstract : Computed tomography (CT) scanned drill cores provide a high resolution view of the internal structure and composition of the rock, which is interesting for many analysis purposes. Although, this data is very high dimensional and difficult to analyze in an automatic way. READ MORE

  4. 13. Studies of pyridine in water clusters with synchrotron radiation and 3D momentum spectrometry

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Benjamin Bolling; [2017]
    Keywords : Physics and Astronomy;

    Abstract : By using the site-selectivity enabled by synchrotron radiation, we can choose the ionization site on a molecule. Core-ionization can result in that the molecule dissociates into charged (and uncharged) ions. With mass spectroscopy, the dissociated fragments’ mass-over-charge can be identified in a time-of-flight spectrum. READ MORE

  5. 14. A differential spectroscopic study of a faint solar twin in the open cluster M67

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Carlos Fernández Ortega; [2016]
    Keywords : Solar twin; difference spectrum; chemical composition; Bessó solar; espectre diferencia; composició química; Soltvilling; differensspektrum; kemisk sammansättning; Gemelo solar; espectro diferencia; composición química;

    Abstract : A solar twin is a star with characteristics very similar to those of the Sun. This is, a Sun-like star. Earlier studies show that M67-1194 is one of the best solar twins found to date. But this star is not exactly like the Sun. READ MORE

  6. 15. X-Ray Photoelectron Spectroscopy of Metal & Metal-based Clusters: Au, Ag & Sn Cases.

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Charles Wright; [2016]
    Keywords : Physics; Photoelectron; Spectroscopy; Cluster; Clusters; Gold; Silver; Tin; Synchrotron; X-Ray; Physics and Astronomy;

    Abstract : Clusters are particles which consist of a finite number (2 − 10 ^6−7 ) of atoms/molecules. For the work presented in this thesis free clusters have been produced in order to study their properties, free of interfering substrates, using photoelectron spectroscopy at the MAX-lab synchrotron facility in Lund, Sweden.
