Anopheles (Shannoniezia) costalimai Fonseca e Ramos, 1940, novo nome e a redescrição da espécie (Diptera-Culicidae)

O autor trabalhando com material de Paranaguá (Paraná, Brasil) identificou varios exemplares de A. (Sh.) costalimais (=limai). Redescreveu a espécie, apresentando descrição da larva e pupa. Por sua solicitação os autores da espécie propuzeram um nome novo para a espécie pro achar-se o nome limai ocupado com uma variedade de A. (N) albitarsis descrita por Galvão de Lane, 1937. Conservou valido o sub-gênero Shannoniezia criado por Fonseca e Ramos 1940. Discute no trabalho o diagnóstico diferencial entre A. (Sh.) costalimai e A. (Sh.) mediopunctatus. Refere-se de passagem a A. (Sh.) costai não opina por sua validade. Refere-se ao material com que trabalharam Bonne e Bonne Webster achando que estes autores trabalharam com mais de uma espécie, pois não há concordância nas descrições para especimens de localidades diversas.

Demand and revenue implications of an integrated public transport policy: the case of Madrid

One of the most popular options for promoting public transport use is the provision of an integrated and high quality public transport system. This was the strategy adopted by the regional government in Madrid in 1986 and since then public transport patronage has increased by more than 50%. This paper has two objectives. The first is to identify the factors underlying the significant increase in the demand for public transport in Madrid. To do this we estimate an aggregate demand function for bus and underground trips, which allows us to obtain the demand elasticities with respect to the main attributes of public transport services and also to calculate the long-term impact of changes in those explanatory variables on patronage. The second objective is to evaluate the impact on revenue derived from the introduction of the travel card scheme, and to discuss the consequences on revenue of changes in the relative fare levels of different types of ticket without substantially affecting patronage. This latter issue is addressed by estimating a matrix of own and cross-price elasticities for different ticket types.

Insecta Amapaensia: Diptera conopidae: espécies do gênero Stylogaster macquart, 1835

Dans le présent travail quatre espèces nouvelles de Stylogaster Macq. ont été décrites avec le dessin des respectives "genitalia" pour mieux déterminer les espéces. Ils ont été faits aussi dessins du mâle de Stylogaster stylata Fabricius pour la comparaison avec S. souzai sp. n. Nous avons utilisé, pour cette étude, le matériel collecté par John Lane au Território do Amapá, Brasil en 1957, 1958 et 1959.

Modelo de comunicación basado en el estándar AMBA AHB

Amb aquest projecte es presenta un model de comunicacions basat en ARM AMBA AHB, escrit en SystemC i dissenyat per a utilitzar-se en qualsevol sistema que necessiti una solució per a les seves comunicacions. Amb aquest objectiu s'escriu de manera que es llancin els seus processos com a processos "threads" i així puguin ser programats des del codi utilitari per mitjà de variables compartides. Per assegurar el correcte funcionament, inicialment es prova en un bus AMBA AHB complet per, un cop comprovat el compliment de l'estàndard, provar-ho en un codi que realitzi el càlcul de la transposició de matrius.

Dysproteinaemia in the differential diagnosis of kala-azar

Serum protein abnormalities were examined in six kala-azar (KA) patients, six controls with positive immunofluorescence tests with Leishmania donovani antigens, and six seronegative controls. KA patients were clearly distinguishable from controls by several parameters, including A/G ratio, albumin and globulin levels, IgM and IgG titers, and positive rheumatoid factor (RF) tests. A positive relationship was noted between RF titers and serum levels of IgM. The diagnostic value and possibel pathologic significance of serum abnormalities in KA is discussed.

Host factors influencing outcome of Leishmania mexicana infection in mice

Studies were undertaken to determine the influence of several host-related parameters on the course of Leishmania mexicana mexicana infection in inbred C57B1/10 (C57) and outbred albino (OA) mice. An important influence of the following variables was demonstrated: Host strain: lesions in C57s were significantly less variable in size and outcome than those of OAs under the conditions studied and even when persistent developed at a slower rate. Host age: Subcutanous injection of 2 x 10 [raised to the power of 4] to 2 x 10 [raised to the power of 6] amastigotes into the dorsum of the rear paw produced significantly larger lesions which healed more slowly in 2 mo. old C57s than in 4 mo. old mice. Reduced healing ability was observed in older (8 mo. old) female C57s, and low mortality occurred after 15 months of age in infected mice of both sexes. Lesion site: Following amastigote infection, lesions in paws of most C57s regress within 15 - 25 wks. In contrast, perinasal legions produced with the same number of parasites tend to persist for the life of the animal as slowly spreading irregular nodules. In animals infected in both locations, each lesion site behaves similarly to that in singly infected animals of the same age, i.e. regression in the two sites is independent. Our results indicate that while host strain may strongly influence infection outcoem, such variables as lesion site and host age play important roles and may explain, in part, reported inter- and intraexperimental variability in responses of murine hosts to a given leishmanial parasite.
