Distribution of Idanthyrsus cretus(Polychaeta:Sabellariidae) in the Tropical Eastern Pacific and application of PCR-RAPD for population analysis.
No full textSabellariid polychaetes, commonly known as honeycomb worms, are capable of forming large reef-like aggregations. One species, Idanthyrsus cretus, has recently been found in several localities during surveys of Las Perlas Archipelago, Pacific Panama. Large reefs of this species have not been recorded elsewhere in the Tropical Eastern Pacific. The reef distribution patterns were examined and mapped with the aid of Geographical Information Systems. Principal Component Analysis showed that the distribution of polychaete reefs in Las Perlas Archipelago and the reef building itself seem to be mainly dependent on depth, suitable substrate, and topography,the potential particle size for tube building, and wave exposure. Cluster analysis of Random Amplified Polymorphic DNA with Polymerase Chain Reaction molecular techniques demonstrated that the polychaete reefs in Las Perlas Archipelago may be derived from one population

La venta de perlas en la ciudad de Roma durante el Alto Imperio
No full textResumen: El comercio de perlas en la ciudad de Roma se atestigua por primera vez a inicios del periodo imperial. Fue necesaria una amplia red comercial que posibilitase la extracción de perlas desde lugares tan remotos como la India, el Mar Rojo, etc., para poder distribuirlas en la capital. Comercio de lujo encargado en última instancia de su venta al por menor a los margaritarii , o vendedores de perlas. Para un mayor conocimiento de estos personajes hemos realizado un estudio sobre la epigrafía lapidaria referida a ellos en Roma. Abstract: Pearl trade in Rome is attested in the early imperial period. For distribution in the capital was required extensive sales network able to extract these pearls from places like India, the Red Sea, etc. The sellers of pearls or margaritarii were responsible for the luxury trade. For a better understanding of these characters we have made a study of lapidary inscriptions concerning them

Las perlas de esmalte son una anomalía del desarrollo dental, que se presentan como glóbulos ectópicos de esmalte en la superficie radicular. La prevalencia media de perlas de esmalte es 2,69%; teniendo predilección por los molares y rara vez se asocian con premolares, caninos o incisivos. La teoría sugiere que se desarrollan debido a presencia de remanentes de la vaina epitelial radicular (de Hertwig). Adquieren real relevancia debido a su asociación como factor retentivo de placa subgingival y a enfermedad periodontal localizada.Publicada en la categoría "Imagénes en Odontología Clínica" de la revista Mouth.

BANKING RATING IN ROMANIA. A COMPARATIVE ANALYSIS BETWEEN CAAMPL AND PERLAS MODELS
No full textIn this paper the author presents the evaluation method of the crediting risk in 20 Romanian banks, based on the
unique rating systems called CAAMPL and PERLAS models. The content of each component of this system is taken into
consideration and also the group of values attached to every component of credit risk analysis is highlighted. Finally, the

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
