[eng] According to the « Fundamental Consensus » which was at the bottom of the creation of the EEC, the Federal Republic of Germany was to benefit from the Common Market mainly in the field of industry while France was assumed to exploit market potentials by growing exports of agricultural...

Predictions, as made in Leach et al. (A low-energy strategy for the United Kingdom. Science Reviews Ltd., Austria: International Institute for Environment and Development, 1979.) have been compared with actual values for subsequent years. Their disparities are discussed, together with the...

Photovoltaic (PV) hybrid systems can make a positive contribution to the sustainability of rural communities in developing countries that do not have access to electricity grid. Integration of solar photovoltaic system with diesel generator for remote and rural areas would assist in expanding...

Solar food dryers are available in a range of size and design and are used for drying various food products. Testing a dryer is necessary to evaluate its absolute and comparative performance with other dryers and the test results provide relevant information for the designer as well as the user....

The study examines the fate of community forestry in the real-world context of pressures through the state and from the market, by using a combination of discourse analysis, actor analysis and net-work analysis.It deals with the views and interactions of a wide range of groups, including...

We study a tight binding model including both on site disorder and coupling of the electrons to randomly oriented magnetic moments. The transport properties are calculated via the Kubo-Greenwood scheme, using the exact eigenstates of the disordered system and large system size extrapolation of...

We propose a scheme for constructing classical spin Hamiltonians from Hunds coupled spin-fermion models in the limit J<Subscript>H</Subscript>/t →∞. The strong coupling between fermions and the core spins requires self-consistent calculation of the effective exchange in the model, either in the presence of...</subscript>
