Reconstruction of rift basins in the Eastern Cordillera and Middle Magdalena Valley, Colombia: Analysis of the extensional phase and structural styles of tectonic inversion
(2022-11-28)The Middle Magdalena Valley (MMV) and the Eastern Cordillera (EC) are regional tectonic units of the northern Andes in Colombia that comprise a total area of about 100.000 km2. The MMV is an intermontane basin located ... -
Political Change and Urban Growth in a Medium-sized Outer Island Capital in Indonesia: The Case of Palu, Central Sulawesi
(2022-11-28)Purpose: This study examines how Palu’s urban development was affected by centralization and subsequent decentralization policies as well as how these shaped the local government and society. This study also explores local ... -
Modelling the porosity loss in granular iron based permeable reactive barriers
(2022-11-24)The quality of groundwater resources globally has been under serious threat due to their exposure to a broad spectrum of anthropogenic pollutants. Permeable reactive barriers (PRBs) are an innovative technology being used ... -
Numerical simulation of permeability heterogeneity in single- and two-phase flow systems to assess the performance of enhanced geothermal system
(2022-11-09)The development of Enhanced Geothermal System (EGS) technology leads to the possibility of an extensive application of geothermal energy, which is attractive because of its ability to reduce CO2 emissions and dependence ... -
Violence and volume: an experimental study of CO2 driven eruptions of Colli Albani
(2022-04-07)This thesis presents the first rheological investigations of melts from the Colli Albani Volcanic District (CAVD) near Rome (Italy). Despite their silica-poor (< 45 wt%) and ultrapotassic composition – indicating a low ... -
Triple oxygen isotope ratios of bioapatite
(2022-04-07)Bioapatite is the major crystalline component of bone and tooth materials. Recent studies demonstrated that bioapatite carries information of animals’ physiology and living environmental conditions and retains its original ... -
A geobiological approach to carbonate factories and ecosystem changes across the Permian–Triassic boundary
(2022-04-05)Contemporary climate change is accelerating. Meanwhile, “Has the Earth’s sixth mass extinction already arrived?” is inquired. The Permian–Triassic crisis, as a possible analog in the Earth history, has aroused great ... -
Triple oxygen isotope study on the Earth-Moon system
(2021-12-23)Triple oxygen isotope systematics (Δ'17O) are an established tool to trace and classify extraterrestrial material. This tool is used in the field of cosmochemistry to study the genetic link between different Solar System ... -
Volcanic tuffs as natural building stones
(2021-11-19)The present thesis deals with the deterioration and durability of volcanic tuff rocks used as building stones in historical architecture and presents a combined approach on identifying the main parameters responsible for ... -
Experimentelle Untersuchungen zu Mechanismen von druck- und temperaturinduzierten Phasenübergängen
(2021-10-18)Under the influence of pressure and/or temperature changes, crystalline materials undergo a phase transition. The directions of the crystalline unit cell before and after the phase transition can show orientation relations. ... -
Geoecological analysis of forest distribution and post-disturbance tree regrowth in the forest-steppe of central Mongolia
(2021-09-09)The Mongolian forest-steppe is an ecotone at the transition between the Siberian Taiga in the north and the Gobi Desert in the south. The highly continental, semiarid climate magnifies the importance of water availability ... -
Forest Landscape Restoration and Ecosystem Services in A Luoi District, Thua Thien Hue Province, Vietnam
(2021-07-23)Abstract The Government of Vietnam has invested efforts to increase the forest cover, and to conserve biodiversity through different forest development projects and programs. Losing natural forests and landscapes in the ... -
