11. The cell wall ultrastructure of wood fibres : effects of the chemical pulp fibre line
Sammanfattning : Knowledge of the ultrastructural arrangement within wood fibres is important for understanding the mechanical properties of the fibres themselves, as well as for understanding and controlling the ultrastructural changes that occur during pulp processing. The object of this work was to explore the use of atomic force microscopy (AFM) in studies of the cell wall ultrastructure and to see how this structure is affected in the kraft pulp fibre line.

12. Adhesion Dependent Signals : Cell Survival, Receptor Crosstalk and Mechanostimulation
Sammanfattning : The integrin family of cell surface receptors is evolutionary conserved and found in all multicellular animals. In humans 8-alpha and 18-beta integrins are non-covalently associated into 24 dimers. Integrins mediate cell-extracellular matrix and cell-cell interactions and participate in cell signalling.

13. Novel insights into protist diversity and niche adaptation using single cell transcriptomics
Sammanfattning : Protists are a polyphyletic group of microbes that represents the vast majority of eukaryotic diversity. Despite this, most sequencing efforts targeting eukaryotes have been focused on animals, fungi and plants. LÄS MER
14. Studies of cell migration and matrix protease production in human lung cancer cell lines
Sammanfattning : Metastatic spread in cancer is a complex multistep process involving continuous, sequential interactions between tumour cells and their respective microenvironment. Invasiveness per se has not been studied in this thesis, only some of its major components, such as cell migration and matrix protease production. LÄS MER
15. Spatial Resource Allocation in Massive MIMO Communications : From Cellular to Cell-Free
Sammanfattning : Massive MIMO (multiple-input multiple-output) is considered as an heir of the multi-user MIMO technology and it has gained lots of attention from both academia and industry since the last decade. By equipping base stations (BSs) with hundreds of antennas in a compact array or a distributed manner, this new technology can provide very large multiplexing gains by serving many users on the same time-frequency resources and thereby bring significant improvements in spectral efficiency (SE) and energy efficiency (EE) over the current wireless networks.
