Building a Decision Support System for Agricultural Land Use Planning and Sustainable Management at the District Level in Vietnam
(2010-02-05)This research aims at developing a decision support system (DSS) to improve the decision-making capacity of administrators as well as other interested parties. The system will help develop ... -
Calcretes aus jungpaläozoischen Bodenbildungen - ein möglicher Proxy für die CO<sub>2</sub>-Konzentration der Paläoatmosphäre
(2003-04-03)The use of pedogenic carbonates (calcretes) in estimating CO2 concentrations in the Late Paleozoic atmosphere has been examined. For this purpose Cerling (1991,1999) submitted a theory based ... -
Carbon Dioxide un ultrapotassic silicate melts: Experimental insights on solubility and decompression induced vesicle nucleation
(2021-10-01)Until today, the explosivity of volcanic eruptions cannot be forecasted by even the most modern monitoring techniques. The processes causing these events, endangering the lives of millions of people, happen deep inside the ... -
Carbonate factories in the early Archean and their geobiological impacts
(2023-08-08)Paleoarchean carbonates in the Pilbara Craton (Western Australia) are important archives for early life and environment on early Earth. Amongst others, carbonates occur in interstitial spaces of ca. 3.5–3.4 Ga pillow basalts ... -
Cathodoluminescence and characterisation of defect structures in quartz with applications to the study of granitic rocks
(2001-03-06)The presented study contributes in solving the causes of cathodoluminescence (CL) of quartz. For this purpose a variety of quartzes from different geological environments has been systematically ... -
