1. 1. Measuring copper abundances in the Galactic Bulge

   Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Författare :Nikolei Höglinger; [2024]
   Nyckelord :Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

   Sammanfattning : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

3. 2. Virtual H&E Staining Using PLS Microscopy and Neural Networks

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Sally Vizins; Hanna Råhnängen; [2024]
   Nyckelord :Deep learning; Virtual staining; Skin tissue; Hematoxylin Eosin; H E; Pathology; Carcinoma; Point light source illumination; Neural Networks; GANs; Generative adversarial networks; CNNs; Convolutional neural networks; Relativistic generative adversarial network; Unet; Digital microscopy; Attention-Unet; Dense-Unet; Mathematics and Statistics;

   Sammanfattning : Histopathological examination, crucial in diagnosing diseases such as cancer, traditionally relies on time- and resource-consuming, poorly standardized chemical staining for tissue visualization. This thesis presents a novel digital alternative using generative neural networks and a point light source (PLS) microscope to transform unstained skin tissue images into their stained counterparts.

4. 3. Ecological Fashion Perspectives of the Green Generation: Examining Gen Z and Millennial attitudes towards the Swedish fashion industry's efforts to reduce emissions of greenhouse gases

   Kandidat-uppsats, Göteborgs universitet/Institutionen för globala studier

   Författare :Amanda Håkansson; [2023-10-18]
   Nyckelord :sustainable development; fashion industry; environmental discourses; greenhouse gas emissions; attitudes;

   Sammanfattning : This paper seeks to examine how young Swedish consumers appurtenant to Generation Z and the Millennial generation perceive the effort made by four leading Swedish fashion companies H&M, Lindex, Kappahl, and Gina Tricot to reduce their emissions of greenhouse gases. Further, it explores the general attitudes that these generations hold toward the Swedish Fashion Industry’s approach to sustainable dev elopment. LÄS MER

5. 4. Johannesört – effektiv behandling vid infektioner? : Medicinalväxten Hypericum perforatum L. och dess antibakteriella aktivitet mot multiresistenta Staphylococcus aureus 

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

   Författare :Amelie Carlsson; [2023]
   Nyckelord :antibakteriell aktivitet; buljongspädningsmetoden; antibiotikaresistens; Hypericum perforatum L.; Staphylococcus aureus; in vitro;

   Sammanfattning : Antibiotic resistance is a rapidly increasing and serious global problem, with infectious diseases currently being the second leading cause of death worldwide. The World Health Organization (WHO) has estimated that 700,000 people worldwide die each year as a result of antibiotic resistance, and this number is projected to rise to 10 million per year by 2050 if no action is taken.

7. 5. Effects of phosphorylation on the ADP-ribosylation activity of PARP16

   Kandidat-uppsats, Lunds universitet/Kemiska institutionen

   Författare :Virginia Martín Cristóbal; [2023]
   Nyckelord :ADP-ribosylation; Kinases; PARP16; Phosphorylation; UPR biochemistry; Biochemistry; Chemistry;

   Sammanfattning : PARP16/ARTD15 is an intracellular mono-ADP-ribosyltransferase that catalyzes auto- and heteromodification by transfer of a single ADP-ribose moiety. It belongs to the ADP-ribosyltransferase (ART) superfamily. LÄS MER
