6. Contentious countrysides : social movements reworking and resisting public healthcare restructuring in rural Sweden
Sammanfattning : The broader aim of this thesis is to contribute to the understanding of the production and reproduction of spatial inequalities following from the restructuring of the public healthcare system. More specifically, by analyzing the contention around healthcare restructuring related to two cases spanning a longer period in northern Sweden, I aim to investigate the changing conditions for healthcare provision in rural and sparsely populated areas, and I explore the forms of collective action that local people engage in to sustain the access to healthcare, as well as how state authorities’ attitudes towards such collective action have shifted.

7. The effectiveness of a full-mobility architecture for wireless mobile computing and personal communications
Sammanfattning : The emergence of wireless mobile computing, especially the mobility of computers, introduces challenging new problems that were encountered in neither the design and implementation of conventional mobile networks or in fixed computer networks. A critical and challenging problem, for mobile computing and personal communications, is how to fully cope with the special characteristics of the mobile wireless environment, i. LÄS MER
8. Electrochemical (bio-)sensors operating in human physiological fluids
Sammanfattning : This thesis is focused on developing electrochemical (bio-)sensors specifically designed to detect biomolecules and bacteria in human physiological fluids. A more comprehensive understanding of their performance can be obtained by exposing the sensors to real human physiological fluids. LÄS MER
9. Facilitating electron transfer in bioelectrocatalytic systems
Sammanfattning : Bioelectrocatalytic systems are based on biological entities, such as enzymes, whole cells, parts of cells or tissues, which catalyse electrochemical processes that involve the interaction between chemical change and electrical energy. In all cases, biocatalysis is implemented by enzymes, isolated or residing inside cells or part of cells. LÄS MER
10. QPM Devices in KTA and RKTP
Sammanfattning : Even though KTiOPO4 (KTP) is considered to be one of the best nonlinear materials for quasi phase matched (QPM) frequency conversion in the visible and the near-infrared spectral regions, its use is often limited by poor material homogeneity, high ionic conductivity, a considerable linear absorption and photochromatic damage. On the other hand, the improved material homogeneity and the lower ionic conductivity of bulk Rb-doped KTP (RKTP) make this material an ideal alternative for fabrication of fine-pitch QPM gratings, while the arsenate isomorph KTiOAsO4 (KTA) promises a better performance in the green spectral region and adds the advantage of a wider transparency window in the infrared.
