Popular Abstract in Swedish Det övergripande syftet med denna avhandling var att studera sambandet mellan skelettmuskulaturens struktur och funktion för att på sikt få ökade kunskaper om de bakomliggande mekanismerna vid muskulär svaghet och uttröttbarhet hos personer med olika skador eller sjukdomar. Mätningarna valdes att göras på musklerna på underbenets framsida, ankelns dorsalflexorer, dels sThe overall aim of this thesis was to increase our knowledge of the relationship between structure and function of human skeletal muscle, and about factors affecting strength. The ankle dorsiflexor muscles (DF) were chosen as a representative model of human skeletal muscle, and because these muscles have important roles in gait and maintenance of balance. Specific aims in this thesis were: i) to d

Popular Abstract in English Parasites and their host organisms have engaged in a desperate battle over millions of years to evolve strategies that enable continued survival of their respective species. Parasites require some key metabolites to be able to survive and reproduce inside the host that often results in damage to host, while host organisms attempt to limit or prevent this damage by severHaemosporidia is a well-studied group of parasites, which infect mammals, reptiles and birds and use blood sucking vectors for their transmission. By conducting natural population studies and experimental infections, We have been able to detect and quantify Haemosporidia from avian blood to investigate how these pathogens affect their avian hosts. We have used life history data of two long-term lo

Demands for efficient, economical and fast separation and purification methods for various target molecules have led to the development of new techniques and materials for bioseparation processes. Separation can be carried out in both batch and chromatographic modes. Running the separation step in a conventional chromatographic column is more efficient than batch mode, but there are some limitatio

An energy system that relies on fossil fuel is not sustainable. Emissions, such as carbon dioxide, nitric oxide and corpuscles, affect the climate and pollute the air. Furthermore, the supply of oil, coal and natural gas is located a few places worldwide, which can give rise to geopolitical conflicts for access to these areas. This is not a local issue for Tjörn, nor even a national issue for Swed

The present thesis presents pressure-temperature and geochronological data from the high-grade mafic rocks from the Southwest Swedish Granulite Region, which forms part of the southwestern Baltic Shield. The region is characterized by variably deformed and migmatized granitic to intermediate gneisses, metabasites and charnockites metamorphosed in granulite and upper amphibolite facies. The peak m

A 50-MS/s two-step flash-ΔΣ time-to-digital converter (TDC) using a 2-channel time-interleaved time-domain register with an implicit adder/subtractor demonstrates a 3rd order noise-shaping. The TDC is fabricated in 40-nm CMOS and consumes 1.2 mA from a 1.1 V supply. At frequencies below 1.25 MHz, the TDC error integrates to 103 fsrms, which is equal to an equivalent resolution of 1.6 ps.
