Estudos anatômicos e histológicos, principalmente do aparelho genital de Bulimulus corumbaensis Pilsbry, 1897: (Gastropoda, Pulmonata, Bulimulidae)

No trabalho apresentado os autores fazem um estudo sôbre a estrutura anatômica e histológica do aparelho genital de Bulimulus corumbaensis Pilsbry, 1897, considerando também a descrição da concha, mandíbula, rádula e câmara paleal. Esta espécie, que era conhecida apenas pelos seus caracteres conchiológicos, apresenta como caracteres importantes para a sua diagnose a morfologia e a estrutura das seguintes partes: 1 - Conchas de adultos com comprimento variando entre 19 mm e 29 mm. Muito característico nesta espécie é sua ornamentação com faixas axiais translúcidas e opacas. As primeiras variam de incolores a castanhas com tôdas as tonalidades. Devido a isto, conforme a intensidade da pigmentação e a freqüência das faixas translúcidas, a coloração da concha fica entre o branco e o castanho. Nas conchas totalmente brancas, existem faixas axiais translúcidas (desprovidas de pigmentação castanha) e faixas branco opacas intercaladas. As conchas intensamente castanhas, apresentam esta tonalidade pela proximidade das faixas castanhas translúcidas. 2 - Ovotestis constiuído por numerosos grupos de folículos bem individualizados, variando nos exemplares dissecados de 4 a 6. 3 - "Talon" aproximadamente três vêzes menor que o canal hermafrodita, apresentando-se dividido em dois tubos. O menos, situado no lado oposto à entrada do canal hermafrodita, histològicamente, é constituído por um único tupo de luz ampla. O maior, situado entre o canal hermafrodita e o tubo acima referido, microscòpicamente mostra 7 túbulos, que em alturas diferentes vão desembocar no tubo menor. O canal hermafrodita, por sua vez, desemboca um pouco mais abaixo. 4 - A bainha muscular do pênis, que é bem desenvolvida, é atravessada aproximadamente na metade do seu comprimetno pelo canal deferente. 5 - Porção proximal do falus apresentando 5 glândulas tubulosas ramificadas, distribuídas do seguinte modo: posteriormente são em número de 4, dispostas envolvendo a luz central do pênis e nela desembocando em alturas variáveis. A outra glândula, anteriormente situada, tem numerosos septos e resulta de uma divisão da luz central do pênis, com modificação do epitélio que se tornou glandular. 6 - A inserção do músculo retrator no flagelo é subterminal.

La Mayor dotación de capital humano y sus problemas de adaptación en el mercado de trabajo español, 1986-2005

Desde 1975 y sobre todo a partir de su incorporación a la Unión Europea en 1986, los cambios que se han producido en la estructura económica y productiva española han favorecido la convergencia de la mayoría de sus indicadores económicos con los de los países de la Unión. Sin embargo, no ha habido el mismo éxito por lo que se refiere al mercado de trabajo. Esta comunicación es, por una parte, el resultado de mi trabajo de investigación sobre la evolución de la educación superior y el mercado de trabajo en España durante las últimas cuatro décadas del último siglo y, por otra parte, el punto de partida de un estudio más profundo sobre las diferencias regionales en la correspondencia entre la oferta y la demanda de trabajo cualificado en España y en Europa. El objetivo de esta comunicación es comparar la evolución de los niveles educativos y de los principales indicadores del mercado de trabajo en España y en otros países europeos (Alemania, Francia, Grecia, Italia, Portugal y Reino Unido) desde 1986, año de incorporación de España a la Unión Europea, hasta la actualidad, para determinar los factores o mecanismos que influyen en el mercado de trabajo cualificado español y su difícil convergencia con los de otros países europeos.

La producción científica sobre comportamientos demográficos diferenciales de la población extranjera en España (1986-2006)

L’objectiu d’aquest treball és l’anàlisi de la producció científica sobre els comportaments demogràfics diferencials de la població estrangera a Espanya durant el període 1986-2006. Per aquest motiu, s’ha realitzat una exploració bibliogràfica sobre migracions internacionals en general amb més de 1.800 referències; analitzant de forma exhaustiva la producció dedicada a l’estudi de les dinàmiques demogràfiques dels estrangers (natalitat i fecunditat, nupcialitat, mortalitat i migracions internes). Així mateix s’ha realitzat un recorregut per l’evolució recent dels tres factors que es consideren que incideixen en la producció científica: l’activitat legislativa, les mesures institucionals i la producció estadística.

An outbreak of dengue virus at Rio de Janeiro - 1986

Dengue virus type 1 has been isolated in Aedes albopictus cell strain, from sera of patients living in the Nova Iguaçu county, by Rio de Janeiro. The clinical picture was characterized by fever, headache, retrobulbar pain, backache, pains in the muscles and the joints and prostration. Studies in paired sera confirmed the presence of recent infection by dengue virus type 1. The outbreak reached adjacent areas, including Rio de Janeiro city (May, 1986).

La reconfiguració de la frontera hispano-marroquina (1986-2010)

Projecte de recerca elaborat a partir d’una estada a la Universitat Abdelmalek Essaadi, Marroc durant gener i febrer de 2007. S’analitzen els principals aspectes del procés de reconfiguració de la frontera hispano-marroquina, que segueix l’accés d’Espanya a la Unió Europea, l’any 1986. L'estudi s’estructura en tres parts, a través de les quals s’exploren les dimensions geopolítica, funcional i simbòlica del procés de refronterització. Partint de l’escenari general de la frontera hispano-marroquina, l’anàlisi s’aproxima gradualment als escenaris particulars construïts a l’entorn de les fronteres euro-africanes de Ceuta i Melilla –les dues ciutats magribines sota sobirania espanyola. D’aquest manera es descriu com el procés tripartit de refronterització ha forjat la geografia actual d’aquest peculiars segments de la frontera entre la UE/Espanya i el Marroc. L'anàlisi conclou tot subratllant com la frontera hispano-marroquina està condicionada per la creixent divergència entre la implementació de les necessitats securitàries de la frontera exterior de la UE i la gestió fronterera del lliure comerç.

Influência do hospedeiro no ciclo e comprovação do ciclo heteroxeno de Anocentor nitens (Neumann, 1897)

Steers and rabbits were used as experimental hosts for Anocenter nitens during scheduled infections, when ticks were recovered from naturally infected horses. Thus, the influence of the host species on the parasite was evaluated mainly considering parameters related to the engorgement period and pre molting of evolutive stages. It was also observed that almost 5% if the metanymphae and a few more than 1% of metalarvae fall off from the host to molt in the evironment, characterizing cycles in one or more hosts. The heteroxenous cycle is reported for the first time occuring in A. nitens.

Agronomic and commercial performance of four Spanish carob cultivars

The carob tree (Ceratonia siliqua) shows interesting prospects for some coastal Mediterranean growing areas and is widely used for industrial, agricultural, and ornamental purposes. It can be an alternative crop adapted to part-time farming and can also be used to regenerate vegetation in areas with a mild climate and erosion problems. Four Spanish carob cultivars were examined (Banya de Cabra, Duraio, Matalafera, and Rojal) to determine the one that performed the best for planting new orchards in northeastern Spain (Catalonia). The trees in this rain-fed trial (average rainfall of 500 mm) were planted in 1986 using seedling rootstocks that were budded in 1987. The trees were trained using the free-vase system and were spaced 8 x 9 m (138 trees/ha including 12% pollinators). The results showed that ‘Rojal’ was the earliest bearing cultivar. However, no significant differences were observed for cumulative pod production 18 years after budding. With respect to cumulative seed yield, ‘Duraio’ had the highest production (95 kg/tree). The lowest tree vigor (trunk cross-section) was observed in ‘Matalafera’. ‘Rojal’ trees produced the largest pods (average fruit weight of 18.9 g) and lowest seed content (11.8%), while ‘Banya de Cabra’ and ‘Duraio’ produced the smallest fruit (weighing 15.3 and 16.2 g, respectively) with the highest seed content (15.2% and 17.3%, respectively). Gum content, expressed as a percentage of the dry weight, was highest in ‘Duraio’ (56.9%) and was lowest in ‘Rojal’ (54.1%). Thus, in terms of kernel and pod production, ‘Duraio’ appeared to be the best-performing female cultivar for planting new carob orchards

El presente trabajo ofrece un estudio exhaustivo de la Antología de cuentistas españoles contemporáneos, de Francisco García Pavón, obra que contribuyó en su día a la difusión y consolidación del cuento en nuestro país. A través del análisis de las piezas contenidas en sus tres ediciones y de las relaciones que se establecen entre ellas, así como del estudio de la vida y la obra de cada uno de sus autores, puede observarse la evolución que ha experimentado el género en España desde los años de la primera posguerra hasta la década de los ochenta.

Intermediate hosts of schistosoma mansoni in Brazil

The Brazilian planorbidical chart is slowly but progressively been increased by new data. Distribution of vector species of Schistosoma mansoni, according to Paraense, 1986, may be thus resumed: Biomphalaria glabrata - delimited by paralells 13 and 21-S and meridians 39 and 45-W, area of greater dominance (Southerst Bahia, oriental half of Minas Gerais and Espírito Santo). It is observed along the coast line of the state of Sergipe, Alagoas, Pernambuco, Paraíba and Rio Grande do Norte. Starting from there, it is found towards the southwest, in the direction to the Sao Francisco River and South-Center of Minas Gerais. Isolated population may be observed in other states. Its presence is probably, associated to the transmission of schistosomiasis in all areas where it occurs. B. tenagophila - extends it self through a wide strip of coast-line the South of Bahia (17-45"S, 39-15'W), RS(33-41'S, 53-27'W). In Sao Paulo and Rio Grande do Sul states it is found further inland. It is important in schistosomiasis transmission in the Paraíba valley (SP). Isolated populations are observed in the Federal District and Minas Gerais state. B. straminea - better adapter species to climatic variation, having a more dense ditribution in the northeast (41-Wand 110-S), south of Bahia and northeast of Minas Gerais (150 and 180-S, 400 and 440-W) It is less susceptible than B. glabrata, being however the most important responsible for the transmission of S. mansoni in the northeast, chiefly in the northeastern dry area, where it is almost the only transmissive species.

Dengue in the State of Rio de Janeiro, Brazil, 1986-1998

This paper presents epidemiological, laboratory, and clinical data on 12 years of dengue virus activity in the State of Rio de Janeiro from the time the disease was first confirmed virologically in April 1986 through April 1998. DEN-1 and DEN-2 viruses are the serotypes circulating in the state and were responsible for the epidemics reported during the last 12 years. The results published here show both the impact of dengue virus infections on the population and laboratory advances that have improved dengue diagnosis.

Ultrastructure of spermatogenesis and sperm development in Saccocoelioides godoyi Kohn & Froes, 1986 (Digenea, Haploporidae)

Ultrastructural observations of spermatogenesis and sperm development of Saccocoelioides godoyi, an intestinal parasite of Leporinus friderici (Bloch, 1794) are described. The irregular-shaped spermatogonia form a peripheral layer, and show a prominent nucleus. Spermatocytes are larger than spermatogonia, and in the early stage present synaptonemal complex. Spermatids show nuclei smaller than the spermatocytes. Spermiogenesis is characterized by outgrowth of the zone of differentiation, presenting basal bodies, separated by an intercentriolar body. At the end of this process, the spermatozoa are released into the residual cytoplasmic mass. The spermatozoa of S. godoyi are elongate, similar to the pattern described for other Digenea, showing nuclei, mitochondria and two axonemes with the 9+1 configuration. The peripheral cortical microtubules on the dorsal and ventral faces are laterally interrupted.

Seasonal analysis of the number of aeropiles in Anocentor nitens (Neumann, 1897) (Acari: Ixodidae) from the State of Rio de Janeiro, Brazil

Variation between aeropile numbers of the right and left peritrematic plate in male and female Anocentor nitens (Neumann, 1897) is reported from a site in Brazil. From January to December 1998, 146 males and 247 females of A. nitens were recovered from Equus caballus L. in Silva Jardim District, State of Rio de Janeiro. Asymmetry of numbers of aeropiles between right and left plates occurred in 83.6% of the males and 82.2% of the females. Differences in the number of aeropiles between the sexes were not significant. Quantitative variation of aeropiles was correlated to the period of recovery, with significant asymmetry detected in August-September and November-December, mainly in males. Results suggest an adaptation, especially in the male ticks, that expresses itself as greater variation in the number of aeropiles in some periods of the year.
