Sorption of nitrates to activated carbon
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Stormwater is an increasing global threat to water quality in water bodies. Urbanization is expanding, and so is the amount of impermeable surfaces that prevents water seepage into the ground. This is disturbing the natural ... -
Stability of anisotropic perfect fluid spheres with electrical charge when the cosmological constant is included
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06)The main task of this thesis is to investigate the stability of anisotropic perfect fluid spheres with electrical charge when the cosmological constant is included. However, before we get so far we needed to read articles ... -
Stratigraphy and play models of Madagascar
(Masteroppgave/UIS-TN-IMN/2009;, Master thesis, 2011)Three western sedimentary basins (Morondava, Majunga and Ambilobe) constitute the main area of interest regarding the hydrocarbon potential of Madagascar. They result from the separation of the island from Africa. Nine ... -
Study of Environmental Regulations for Emissions to Air in the EU and the US, and to understand guidelines of regulations in the EU by considering a case of aluminum industry
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06)Climate change and high level of atmospheric pollution is a global problem that has taken on particular significance in recent years and will continue to grow in the near future. To deal with this problem, it is very ... -
