1. Observation strategies for current and future geodetic very long baseline interferometry
Detta är en avhandling från ; Chalmers tekniska högskola; GothenburgSammanfattning : Geodetic Very Long Baseline Interferometry (VLBI) is an essential technique for space geodesy. It is uniquely capable of simultaneously observing all Earth Orientation Parameters (EOP) and directly giving access to the Earth’s rotation angle (related to Universal Time, UT1). LÄS MER
2. Coal and Oil: The Dark Monarchs of Global Energy Understanding Supply and Extraction Patterns and their Importance for Future Production
Detta är en avhandling från Uppsala : Acta Acta Universitatis UpsaliensisSammanfattning : The formation of modern society has been dominated by coal and oil, and together these two fossil fuels account for nearly two thirds of all primary energy used by mankind. This makes future production a key question for future social development and this thesis attempts to answer whether it is possible to rely on an assumption of ever increasing production of coal and oil.

3. Depletion and decline curve analysis in crude oil production
Detta är en avhandling från Uppsala : Global Energy Systems, Department for Physics and Astronomy, Uppsala UniversitySammanfattning : Oil is the black blood that runs through the veins of the modern global energy system. While being the dominant source of energy, oil has also brought wealth and power to the western world. Future supply for oil is unsure or even expected to decrease due to limitations imposed by peak oil. Energy is fundamental to all parts of society. LÄS MER
4. Particle Emissions from Ships
Detta är en avhandling från Uppsala : Global Energy Systems, Department for Physics and Astronomy, Uppsala UniversitySammanfattning : Since 1st of January 2015 ships operating in sulphur emission control areas (SECAs) have to use marine fuels with a fuel sulphur content less than 0.1 %m/m. This regulation forces the ship owners to make a fuel shift and use low-sulphur marine fuel oils, use alternative fuels or use scrubbers on-board their ships. LÄS MER
5. Origin of organic compounds in fluids from ultramafic-hosted hydrothermal vents of the Mid-Atlantic Ridge
Detta är en avhandling från Stockholm : Department of Geology and Geochemistry, Stockholm UniversitySammanfattning : Natural gas, primarily methane (CH4), is produced in substantial amounts in ultramafic-hosted hydrothermal systems. These systems could also generate oil (heavier hydrocarbons) and the first building blocks of life (prebiotic molecules). In the presence of iron bearing minerals, serpentinisation reactions generate H2. LÄS MER
