In this dissertation the GEONTO–MET methodology is presented. It is oriented to formalize the geographic domain conceptualization according to the specifications of the Instituto Nacional de Estadística, Geografía e Informática (INEGI). The main goal is to provide semantic descriptions, which represent the properties and relations describing so the behavior of geographic objects and taking into...
متن کاملGenome sizes of 227 accessions of Gagea (Liliaceae) discriminate between the species from the Netherlands and reveal new ploidies in Gagea
Nuclear genome size, as measured by flow cytometry with propidium iodide, was used to investigate the relationships within the genus Gagea (Liliaceae), mainly from the Netherlands. The basic chromosome number for Gagea is x = 12. The inferred ploidy in the Dutch and German accessions varies from diploid to decaploid. Consequently there is a large range of genome sizes (DNA 2C-values) from 14.9 ...

We study topological defects arising in the Grand Unification Model SU(6)L ⊗SU(6)c⊗SU(6)R ×Z3. In particular we show the existence of massive magnetic monopoles, cosmic strings and global textures in a particular symmetry breaking chain. We comment on the possible relation to astrophysical problems, in particular to the explanation of the origin of the highest energy cosmic rays reported recent...
متن کاملMolecular systematics of Gagea and Lloydia (Liliaceae; Liliales): implications of analyses of nuclear ribosomal and plastid DNA sequences for infrageneric classification.
BACKGROUND AND AIMS Gagea is a Eurasian genus of petaloid monocots, with a few species in North Africa, comprising between 70 and approximately 275 species depending on the author. Lloydia (thought to be the closest relative of Gagea) consists of 12-20 species that have a mostly eastern Asian distribution. Delimitation of these genera and their subdivisions are unresolved questions in Liliaceae...
متن کاملStudio sull'Ordine dei Costituenti nel Confronto tra Generi e Complessità (Analysis of Constituents Order Across Textual Genres and Complexity)
Italiano. In questo articolo presentiamo uno studio sull’ordine dei costituenti in italiano basato su corpora annotati in maniera automatica fino all’analisi sintattica a dipendenze. L’indagine comparativa ha permesso di valutare l’influenza sia del genere testuale sia della complessità linguistica nella distribuzione dei fenomeni di marcatezza sintattica. English. In this paper we present a st...
