Energy efficiency in biomass production is a major challenge for a future transition to sustainable food and energy provision. This study uses methodologically consistent data on agroecosystem energy flows and different metrics of energetic efficiency from seven regional case studies in North America (USA and Canada) and Europe (Spain and Austria) to investigate energy transitions in Western agroecosystems from the late nineteenth to the late twentieth centuries.

6 p, 737.6 KB First-principles study of isomorphic ('Dual-Defect') substitution in kaolinite / He, Man-Chao (China University of Mining and Technology. State Key Laboratory for Geomechanics and Deep Underground Engineering) ; Zhao, Jian (China University of Mining and Technology. State Key Laboratory for Geomechanics and Deep Underground Engineering) ; Fang, Zhi-Jie (China University of Mining and Technology. State Key Laboratory for Geomechanics and Deep Underground Engineering) ; Zhang, Ping (Institute of Applied Physics and Computational Mathematics)
Kaolinite is often a cause of deformation in soft-rock tunnel engineering, leading to safety problems. In order to gain a better predictive understanding of the governing principles associated with this phenomenon, the physical and chemical properties of kaolinite were investigated using an efficient, first principles scheme for studying isomorphic substitution of Al ions in kaolinite by two kinds of other elements (namely, the dual defect). [...]

The conversion of volcanic glass to secondary alteration products is one of the most common mineralogical transformations during low-temperature hydrothermal alteration of submarine basalts. To better understand the mechanism and kinetics of this transformation, porphyritic and formerly glassy trachybasalt, recovered from Conical Seamount, Papua New Guinea, was studied in detail. [...]
