Un linguaggio di coordinamento per agenti logici abduttivi

In questa tesi si propongono estensioni del linguaggio LAILA di coordinamento tra agenti logico/abduttivi, con particolare riguardo alle primitive di comunicazione e ai meccanismi di consistenza. Delle estensioni verranno fornite sintassi e semantica in stile operazionale. Verranno inoltre forniti due esempi di applicazione, uno in campo medico e l'altro in campo legale, mettendo in luce la maggiore espressività del nuovo linguaggio

The Role of Cuticular Strata Nomenclature in the Systematics of Nemata

A system of cuticular nomenclature based on the strata observed in Enoplia is proposed. Nematode cuticle is divided into four fundamental strata: epicuticle, exocuticle, mesocuticle, and endocuticle. Application of this system allows the correlation of complementary strata throughout Nemata. The major taxonomic categories within Nemata are differentiated on the basis of their cuticular strata as compared with the Enoplia model cuticle

Tribune: Genus and Family: Concepts and Natural Groupings

A little over two hundred and fifty years ago Linnaeus (= Linne) began to maneuver his concepts of animal arrangement into Aristotle’s logic of classes. Twenty-three years elapsed between the publication of his first and tenth editions of Systema naturae. The tenth edition (1758) is the acknowledged starting point of zoological nomenclature. Often forgotten but highly significant is the fact that he spent those intervening twenty years orchestrating the then known animals into the world of philosophy

A Statistical Approach to the Objective Differenciation of \u3ci\u3eHirschmanniella oryzae\u3c/i\u3e from \u3ci\u3eH. belli\u3c/i\u3e (Nemata : Pratylenchidae)

Alternate English title: A Statistical Approach to the Objective Differentiation of Hirschmanniella oryzae from H. belli (Nemata : Pratylenchidae) English language abstract: California populations attributed to Hirschmanniella belli were compared i) to paratypes of this species, ii) to topotypes of H. oryzae, and iii) to other populations of the same genus from other parts of the world. Comparisons were made using discriminant function analyses. Some small differences between California populations and paratypes of H. belli were attributed to artifacts caused by the long storage of these paratypes. Several characters were selected that were not affected by these artifacts, but were successful in differentiating a l1 California specimens (including paratypes of H. belli) from topotypes of H. oryzae. It was verified that a discriminant function analysis using these seven characters was able to separate other California specimens from Hirschmanniella specimens from other origins. The discriminant functions defined by this analysis can be used for practical identification of Hirschmanniella from California. The significance of these results for the taxonomic validity of H. belli is discussed. French language title: Une méthode statistique pour la différentiation objective de Hirschmanniella oryzae et de H. belli (Nemata : Pratylenchidae) French language abstract: Des populations californiennes attribuées à l’espèce Hirschmanniella belli ont étě comparées à : 1) des paratypes de cette même espèce; 2) des totopypes de H. oryzae; et 3) d’autres populations du même genre provenant d’autres régions du monde. Ces comparaisons ont étě faites à l’aide d’analyses discriminantes. De petites différences observées entre les populations californiennes et les paratypes de H. belli ont étě attribuées à des artefacts résultant du grand âge des paratypes. Sept caractères ont étě sélectionnés qui n’étaient pas soumis à l’action de ces artefacts mais qui réussissaient à différencier tous les spécimens californiens (y compris les paratypes de H. belli) des topotypes de H. oryzae. Il a étě vérifié qu’une analyse discriminante utilisant ces sept caractères était capable de séparer d’autres spécimens californiens de spécimens d\u27Hirschmanniella d’autres origines. Les fonctions discriminantes définies par cette analyse peuvent être employées pour l’identification pratique de Hirschmanniella californiens. La signification de ces résultats en ce qui concerne la validité de H. belli est discutée

\u3ci\u3eMeloidogyne californiensis\u3c/i\u3e n. sp. (Nemata: Meloidogyninae), Parasitic on Bulrush, \u3ci\u3eScirpus robustus\u3c/i\u3e Pursh

Meloidogyne californiensis n. sp. is described and illustrated from bulrush Scirpus robustus in California. LM and SEM studies revealed that this species differs from other known species in the genus Meloidogyne especially by the prominent posterior cuticular protuberances in the female, the distinct shape of the perineal pattern which is marked by one prominent stria in the perineum, indistinct lateral lines, many broken discontinuous striae on both sides of the arch, and the excretory pore being located posterior to stylet base. Second-stage juveniles 448-628 μm long, stylet length 11-13 μm, styler delicate, with small knobs sloping posteriorly, cephalic region with 2 or 3 annuli, and inflated rectum. Males vary greatly in size (712-1,952 μm), stylet length 18-28 μm (mean 22 μm), cephalic region slightly set off the body with two or three annuli, spear heavy with massive rounded knobs, lateral field marked by four areolated incisures as seen by SEM
