The Productivity of Crop Rotation Depending on the Included Plants and Soil Tillage

open access: yesAgriculture, 2023
Crop diversification in rotations is an important part of sustainable crop production. The aim of this research was to analyse soil tillage and crop rotation influence on the yield (t ha−1) of different field crops, their energy yield (GJ ha−1) and the ...

Cold-fission yields at effective excitation energies [PDF]

open access: yesPhysical Review C, 1995
The experimental cold-fission yields for the systein 23'~(n,h ,f) are analyzed as function of the effective total excitation energy (TXE). The nuclear level density effect is taken into account at higher TXE, in order to benefit by the lower experimental data uncertainty as well as to avoid the quantitative account of the level densities close to ...

The Mineral Question: How Energy and Technology will determine the Future of Mining

open access: yesFrontiers in Energy Research, 2013
Almost 150 years after that William Stanley Jevons published his paper The Coal Question (Jevons, 1866) the debate on mineral depletion has been ongoing between two main schools of thought: one that sees depletion as an important problem for the near ...
