Gure gizartean, hidrogenoa gero eta garrantzia handiagoa duen energia-iturria da. Ekoizpen-teknika guztien artean, metanoaren ur-lurrun bidezko erreformatzea da erabiliena. Prozesua hurrengo urratsetan oinarritzen da: gas naturalaren garbiketa, beroketa-prozesua, labe erreformatzailea, ur-lurrunaren bihurketa hidrogenoaren bereizketa; erreformatzailea elementurik garrantzitsuena izanik. Dena de...

We present an implementation of a discourse parsing system for a lexicalized Tree-Ajoining Grammar for discourse, specifying the integration of sentence and discourse level processing. Our system is based on the assumption that the compositional aspects of semantics at the discourse-level parallel those at the sentence-level. This coupling is achieved by factoring away inferential semantics and...

We calculate the rate for D s → Dsπ decay using Chiral Perturbation Theory. This isospin violating process results from π η mixing, and its amplitude is proportional to (md − mu)/ ( ms − (mu + md)/2 ) . Experimental information on the branching ratio for D s → Dsπ can provide insight into the pattern of SU(3) violation in radiative D decays.
