1. THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN
University essay from Göteborgs universitet/Institutionen för geovetenskaperAbstract : Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic environments, which in turn may harm the ecological conditions. READ MORE

2. Enhancing Geophysical Applications with Electrical Resistivity Tomography Inversion : Uncovering the mysteries that lies beneath us
University essay from Umeå universitet/Institutionen för fysikAbstract : Geophysical methods have been widely used to investigate the subsurface in various ap-plications, such as mineral exploration, geotechnical and environmental studies. Among these methods, electrical resistivity tomography (ERT) has gained popularity due to its non-invasive and high-resolution capability in mapping subsurface resistivity variations. READ MORE

3. First principles investigation of the thermal conductivity of Zr, ZrC, and ZrN
University essay from KTH/FysikAbstract : The thermal conductivity and electrical resistivity of Zr, ZrC, and ZrN were calculated using first-principles density functional theory (DFT) and the Boltzmann transport equation. The electron-phonon scattering was modeled via the self-energy relaxation time approximation (SERTA), and the phonon-phonon scattering via the analogous single-mode relaxation time approximation (SMRTA).

5. The Influence of Roughness on Electrical Properties of Single Rock Fractures
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : To investigate the relationship between the structural characteristics of rough single fracturesand the electrical properties of the rock. In this study, a series of physical models of roughand smooth single fractures were established using the finite element method and Ohm's lawto test the electrical conductivity. READ MORE
