Esta dissertação propõe a análise da metáfora na construção poética de Carlos Drummond de Andrade, poeta modernista brasileiro, especificamente, nos poemas que tratam da temática do Amor. São analisados trinta e um poemas que compõem a Antologia poética, por ele mesmo organizada. O estudo proposto toma como fundamentação teórica a perspectiva cognitivista de Lakoff e Johnson e Ricoeur, partindo da temática do Amor, em duas perspectivas: a discursiva e a da palavra. Na perspectiva discursiva postulam-se três grandes metáforas: das relações humanas, das relações sociais e das relações com a terra. O conjunto das três metáforas revela uma temática maior: a metáfora do SER, que concretiza o mistério do homem, na poesia de Drummond. A par dessa perspectiva discursiva, postula-se a existência de categorias metafóricas centradas nas palavras e nas expressões linguísticas. Dessa forma, apresenta-se a indissociabilidade das duas perspectivas, mostrando-se que o conceito de metáfora se associa a uma concepção sociocognitivista de língua e que as estratégias linguísticas revelam as categorias metafóricas. Por fim, questiona-se a abordagem na escola básica, especificamente, nos estudos literários da metáfora como ferramenta para o desenvolvimento da competência discursiva dos estudantes dissociado do ensino específico de língua materna

This paper collects most of the information gathered between October 1974 and July 1976 within the framework of a research program concerning the hydrobioclimate of ivorian lagoons and especially the Ebrié lagoon. Monthly surveys concerning the latter were carried out during 1975. The following parameters - and their vertical distribution wherever it had a meaning - were systematically gathered in a system of fifty-five stations: Transparency (Secchi), Temperature, Salinity, Chlorophylla, Dissolved oxygen, phosphate, nitrate, nitrite. These data provide an outline of the annual cycle of nutrients and primary production of the Ivoirian lagoons

This data report contains all the meteorological, hydrological and dynamic data gathered during the VASPI cruises (I : from December 8th to December 13th 1982, II : from March 5th to March 9th 1983, and III : from October 6th to October 10th 1983) carried out along the continental shelf of Ivory Coast by the oceanographic ship "Andre NIZERY". These cruises, which represent a part of a coastal programme, are included in the more general scientific program FOCAL, whose main scientific objective is the study of the thermal context of the intertropical atlantic area.

This work summarizes the present knowledge on biology and fisheries of Atlantic tuna such as yellowfin (Thunnus albacares), skipjack (Katsuwonus pelamis) and to a lesser extent, bigeye (Thunnus obesus) and albacore (Thunnus alalunga). Current appraisal of these stocks

Beach surface temperature is recorded every morning between 7h30 and 8h00 at each coastal station. On figure 2, 3, 4 and 5 it has been plotted daily variation and mean variation computed on 7, 15 and 30 days basis of sea surface temperature. However it seems that variations of dynamic height anomaly are reflecting more accurately the stages of the coastal upwelling than the sea surface temperature.

The Centre de Recherches Océanographiques d'Abidjan has carried out the HYDROBIOCLIMAT program in order to study the seasonal and interannual fluctuations of the physical and biological parameters over the continental shelf of Ivory Coast ; two subsurface moorings with from one to three AANDERAA current meters fixed on the lines, were deployed in front of Abidjan and San Pedro. Temperature and current measurement records are presented at these two locations.

The exploitation of fish stocks in Aby lagoon was marked by an increase of total fishing effort, yields and therefore by the increase of total production. Fishing effort evolution was due to: the increasing of the number of beach seines which has increased from 26 in 1987 to 32 in 1988, the reappearance of syndicat seines and finally the importance of fishing teams activity.
