Iberia-Latin-American Symposia of Morphological Terminology (SILAT). First Two Years and Statute

On the occasion of meeting the first two years of life, it makes a review of SILAT as scientific and educational program that serves as a tool to analyze and solve the problems of morphological medical terminology in the countries of Hispanic and Portuguese-speaking America. It describes the basis of its creation, strategy and scope in the region, the founding years and its immediate future. Finally, some conclusions are indicated and it Statute is annexed.

Ibero-Latin-American Symposium of Morphological Terminology. General Characteristics

It describes the main features of SILAT as a multinational scientific and educational program that serves as a tool to analyze and solve the morphological medical terminology problems in Spanish and Portuguese speaking countries of America. It treated history and creation, members, aims and functions, resources, activities, organizational structure, board, relations with other organizations and publications.

Non-lignified parenchyma in Cactaceae and Portulacaceae

This work describes the occurrence and distribution pattern of non-lignified parenchyma in species of Cactaceae and Portulacaceae, of which samples of roots and stems of six species of Cactaceae and four species of Portulacaceae were analysed. The first records of non-lignified parenchyma in Portulacaceae were obtained and, in the case of Cactaceae, an in-depth discussion is given on the characterization of this tissue by various authors, as well as new information on the occurrence and distribution pattern of the non-lignified parenchyma. The terminology used to characterize the non-lignified parenchyma cells in the wood of Cactaceae is extremely diversified and often not very descriptive, which makes it difficult to establish homologies and better characterize this tissue. Non-lignified parenchyma cells in the secondary xylem in Cactaceae and Portulacaceae occur in association with the fibrous phase of the wood, often forming true continuous bands. This resembles what some authors call parenchyma wood. The proposal of this study is to demonstrate that, independent of the distribution pattern of the non-lignified parenchyma cells, the terminology used should follow that of the International Association of Wood Anatomists (IAWA) Committee as non-lignified parenchyma and not refer to a parenchymous phase of the wood.

Comparative Internal Structure of Dorsal Lips and Radiolar Appendages in Sabellidae (Polychaeta) and Phylogenetic Implications

Fan worms (Sabellidae) possess paired modified prostomial structures at the base of the radiolar crown, dorso-lateral to the mouth, called dorsal lips. The dorsal lips are involved in the sorting of particles collected by the radiolar crown. The range of variation in the morphology of dorsal lips is extensive, and probably this is not only due to adaptations to different environments and feeding preferences but also due to phylogenetic constraints. In this study, we describe and compare the morphology of dorsal lips in a range of sabellid taxa based on histological cross-sections of these structures, and compare our data and terminology with those of previous studies. Dorsal lips are maintained erect in most taxa by a modified radiole fused to them known as dorsal radiolar appendage. We suggest that dorsal radiolar appendages with an internal supporting axis (cellular or acellular) and probably also the ventral lips are synapomorphies of the family. J.

Alignment-based extraction of multiword expressions

Due to idiosyncrasies in their syntax, semantics or frequency, Multiword Expressions (MWEs) have received special attention from the NLP community, as the methods and techniques developed for the treatment of simplex words are not necessarily suitable for them. This is certainly the case for the automatic acquisition of MWEs from corpora. A lot of effort has been directed to the task of automatically identifying them, with considerable success. In this paper, we propose an approach for the identification of MWEs in a multilingual context, as a by-product of a word alignment process, that not only deals with the identification of possible MWE candidates, but also associates some multiword expressions with semantics. The results obtained indicate the feasibility and low costs in terms of tools and resources demanded by this approach, which could, for example, facilitate and speed up lexicographic work.
