Despite various ongoing international initiatives, the intensity and frequency of weather-related natural hazards is expected to continue to increase globally. Increasing our understanding of how to mitigate the consequences of such natural hazards through better detection, planning and preparedness, has constituted the overarching objective of this thesis. The thesis is based on three papers: Pap
Hydropower is a renewable, reliable, and highly predictable source of energy. It has been used for centuries. The tariff of energy generation is divided into two parts: fixed charges and variable charges. Fixed charges are based on the availability of machinery (i.e., plant availability factor) and variable charges are based on the actual energy generation. The energy generation targets are decide

Earth-abundant transition-metal complexes are desirable for sensitizers in dye-sensitized solar cells or photocatalysts. Iron is an obvious choice, but the energy level structure of its typical polypyridyl complexes, featuring low-lying metal-centered states, has made such complexes useless as energy converters. Recently, we synthesized a novel iron-N-heterocyclic carbene complex exhibiting a rema
Li-rich nickel cobalt manganese oxides (LNCM) cathode with full gradient compounds is prepared by using an ethanol assisted co-precipitation method. The rationally designed procedure involves gradient distributions of transition-metal ions, in which the Ni content increases continuously, Mn content decreases gradually and Co keeps at a low level. The employing ethanol during the synthesis adjusts
The primary route to hydrogen production from fossil fuels involves the water-gas shift (WGS) reaction, and an improvement in the efficiency of WGS catalysts could therefore lead to a major leap forward in the realization of hydrogen economy. On the basis of a combination of high-resolution scanning tunneling microscopy, X-ray photoelectron spectroscopy, and density functional theory (DFT) calcula
We examined the association between sports and other leisure-time physical activities during pregnancy and birth weight of babies born after 37 completed weeks of gestation. All Danish-speaking pregnant women attending routine antenatal care at the Department of Obstetrics, Aarhus University Hospital, Denmark, from August 1989 to September 1991 were invited to participate in the study. A total of
Wood components such as cellulose, lignin and hemicelluloses all have potential to be used in biobased value-added products. Once extracted from the wood these components have to be separated and purified from co-extracted compounds. Membrane filtration can be used to achieve this separation and is believed to play an important role in biorefineries.Fouling is the single greatest obstacle to the i
This paper discusses urban sustainable development by comparing two approaches: a place-based sustainability approach which focuses the direct and often production based impacts on a region, and a system-based approach which reveals the indirect and consumption based effects of globalised patterns of production, consumption and trade. Malmö, a small/middle-sized city in Sweden, is used as a case s
Hydropower is one of the renewable energy sources having the highest conversion efficiency than other renewable energy sources. The hydro turbine is considered as the main component of a hydropower plant and operation and maintenance of various components are the critical issues for optimal energy generation. Under the present paper, a comprehensive literature review on the operation and maintenan
This paper investigates the challenges of gender mainstreaming in Swedish municipalities, with a focus on the initial implementation. Since the mid-1990s, gender mainstreaming has been the prevailing strategy within Swedish authorities and public administration to increase gender equality in society. In simple terms, this means that a gender equality perspective must be integrated into all decisio

Fuel cells are promising for future energy systems, because they are energy efficient and able to use renewable fuels. A fully coupled computational fluid dynamics (CFD) approach based on the finite element method, in two-dimensions, is developed to describe a solid oxide fuel cell (SOFC). Governing equations for, gas-phase species, heat momentum, ion and electron transport are implemented and cou
