  1. 16. Size and Abundance of Late Pleistocene Reticulofenestrid Coccoliths from the Eastern Indian Ocean in Relation to Temperature and Aridity

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jeroen van Dijk; [2017]
    Keywords : coccoliths; abundance; biometry; circular polarized light microscopy; Late Pleistocene; Marine Isotope Stage 11; kokkoliter; mängder; biometri; cirkulär polariserat ljus; pleistocen; Marine Isotope Stage 11;

    Abstract : Measurements on coccolith abundance and mass can be used as a signal of primary productivity and pelagic calcification in response to environmental change. The Leeuwin Current (LC) is known to transport warm and low-salinity waters from the Indo-Pacific Warm Pool (IPWP) southwards along the coast of West Australia. READ MORE

  3. 17. Optical Imaging and Spectroscopy of Airborne Nanowires

    University essay from Lunds universitet/Fysiska institutionen

    Author : Eleni Gompou; [2017]
    Keywords : Physics and Astronomy;

    Abstract : Semiconductor nanowires are the potential base for building many future devices like solar cells and light emitting diodes. To reach the level of commercialization of such devices, mass production of NWs at low cost with reproducible high quality properties in terms of crystallinity, material and dimensions is a prerequisite.

  4. 18. Standardization of the Compass Neuropils of the Australian Bogong Moth, Agrotis infusa

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Liv de Vries; [2016]
    Keywords : Biology and Life Sciences;

    Abstract : Every summer the Australian Bogong moth migrates from southern Queensland to the Australian Alps in southern New South Wales. Other migrants such as the monarch butterfly use a time-compensated sun compass. However, the Bogong is nocturnal and only has access to skylight cues such as the moon, polarized light or the Milky Way. READ MORE

  5. 19. To be, or not to be Melanoma : Convolutional neural networks in skin lesion classification

    University essay from KTH/Medicinsk teknik

    Author : Andreas Nylund; [2016]
    Keywords : Clinical Decision Support; Convolutional Neural Networks; Deep Learning; Dermoscopy; Machine Learning; Melanoma;

    Abstract : Machine learning methods provide an opportunity to improve the classification of skin lesions and the early diagnosis of melanoma by providing decision support for general practitioners. So far most studies have been looking at the creation of features that best indicate melanoma. READ MORE

  6. 20. The role of Sema3A in inflammation mediated tumor progressions

    University essay from KTH/Skolan för bioteknologi (BIO)

    Author : Emma Nygren; [2015]
    Keywords : macrophage; T-cells; Tumor ummunology; angiogenesis;

    Abstract : In the tumor microenvironment there are many different cell types present and among these, immune cells display a large proportion. Central players in the tumor immunity are macrophages that come in two different phenotypes, the M1 and M2 macrophages. READ MORE
