i. The paper will try to identify the various concurrent factors which, in the last years, have contributed to the increasing attention paid to the issue of reusable linguistic resources for natural language processing. The role of various major Organisations (EEC, Council of Europe, DARPA, NEH, etc.) will be examined, taking into account the reasons which seem to have stimulated their active p...

Planning and management of water resources is crucial to enhance agricultural productivity ensure food security in drylands. For this, adaptable reliable runoff prediction models are urgently needed support harvesting irrigation development. In this study we explored the potential Curve Number (CN) method estimate daily surface from representative land use types conditions Tigray (north Ethiopi...

Limited previous experience with the mean value total dressing ~MVTD! method had shown that MVTD energies for closed shell systems are generally better than CCSD~T! ones compared to FCI. The method, previously published as total dressing 28(td-28), is based on the single reference intermediate Hamiltonian theory. It is not a CC method but deals in a great part with the same physical effects tha...

Aims. We describe the assignment of a previously unidentified interstellar absorption line to ArH and discuss its relevance in the context of hydride absorption in diffuse gas with a low H2 fraction. The confidence of the assignment to ArH is discussed, and the column densities are determined toward several lines of sight. The results are then discussed in the framework of chemical models, with...
