In this paper two species of trematodes recovered from nectomys squamipes from Goiás State, Brazil, are presented. Maritremopsis mariettavogeae sp. n. is compared to M. proxilum (Caballero & Montero-Gei, 1961) and M. belopolskaiae (Caballero, 1964). Amphimerus lancea originally described from a cetacean host, is for the first time referred in a rodent.

Paragonimus rudis was found in the lungs of a giant otter Lutra (pteronura) brasiliensis by Natterer in 1828, who dissected the animal in the former capital Mato Grosso (=Vila Bela), Brazil. The flukes were described by Diesing in 1850, and redescribed by Braun in 1901. Both descriptions do not allow to identify the species. Therefore, P. rudis must be regarded a "nomen nudum". Because its rediscovery is desirable with regard to historical reasons and nomenclatoric questions, a field study was performed in Mato Grosso in 1980. Of 354 freshwater crabs from 24 localities collected and examined for parasitic infections, about 25% were found to be infected with 7kinds of trematode larvae, which differed distincly from Paragonimus-metacercariae. The question, whether P. rudis or other lung fluke species do not seem to occur or cannot be found any longer in the area investigated by us, is discussed.
El Real Conservatorio de Artes (1824-1850): Orígenes y gestación de la ingeniería industrial moderna
Resumo:
El "Conservatorio de Artes" tuvo un origen Ilustrado, emulando a su homónimo parisino, pero nació durante el absolutismo (1824), tras un frustrado intento afrancesado (1810). Absorbió al "Gabinete de Máquinas" y tuvo como primer director a López de Peñalver. Supuso un puente entre la Ilustración y la Ingeniería Industrial decimonónica, sobre todo, a partir de la institucionalización del envío de pensionados a la "École Centrale des Arts et Manufactures" parisina, con cuyo retorno consigue transformarse en "Real Instituto Industrial" (1850). Aparte destaca su proyección social, tanto en su papel de oficina de patentes como en la promoción de exposiciones industriales.

É feito um estudo dos plerocercos, larvas de Trypanorhyncha, coletados de peixes estuarinos (Bagrus marinus) e de peixes fluviais, da região de Belém, Pará; os peixes fluviais foram a dourada (Brachyplatystoma flavicans) e a piramutaba (Brachyplatystoma vaillanti). Estes plerocercos foram comparados com outros coletados de pescadas (Cynoscion) e corvinas (Micropogonias), do litoral do Rio de Janeiro. Foram identificados à espécie Pterobothrium crassicolle Diesing, 1850; é dada uma redescrição, uma vez que se considerava como espécie imperfeitamente conhecida.

Genuine Savings (GS), also known as ‘net adjusted savings’, is a composite indicator of the sustainability of economic development. Genuine Savings reflects year-on-year changes in the total wealth or capital of a country, including net investment in produced capita, investment in human capital, depletion of natural resources, and damage caused by pollution. A negative Genuine Savings rate suggests that the stock of national wealth is declining and that future utility must be less than current utility, indicating that economic development is non-sustainable (Hamilton and Clemens, 1999). We make use of data over a 150 year period to examine the relationship between Genuine Savings and a number of indicators of well-being over time, and compare the relative changes in human, produced, and components of natural capital over the period. Overall, we find that the magnitude of genuine savings is positively related to changes in future consumption, with some evidence of a cointegrating relationship. However, the relationships between genuine savings and infant mortality or average heights are less clear.

Este trabajo responde a la réplica de Leandro Prados de la Escosura acerca de mi estimación de la serie histórica del Producto Interior Bruto de España (R.E.A., 49 (XVII), 2009, págs. 5 a 45). Demuestra que el IPC es el mejor deflactor disponible para reconstruir el PIB antes de la CNE porque mide correctamente las variaciones interanuales del nivel general de precios. Emplea un procedimiento de enlace de la serie histórica de la contabilidad nacional que es consistente con los nuevos sistemas de cuentas nacionales SCN-93 y SEC-95 y coincide con los empleados por todos los organismos económicos internacionales. La actualización del sistema contable, con la inclusión de la economía sumergida y de la producción para uso final propio, ha dejado obsoletas las estimaciones anteriores y exige estimaciones de segunda generación, con la inevitable readaptación de los niveles relativos de las distintas economías.

Prosthenhystera obesa (Diesing,1850) Travassos, 1922 from the gall bladder of Astyanax bimaculatus, Caranx gibbosus, Galeocharax humeralis, Leporinus copelandii, Pimelodus fur, Pseudopimelodus roosevelti, Salminus brevidens, Salminus maxillosus and from the new hosts, Cynopotamus amazonum and Triurobrycon lundii is redescribed, demonstrating a large morphological variation, mainly in body and testes size and shape. New hosts harbouring immature specimens of P. obesa are presented: Brycon sp., Leporellus vittatus, Pachyurus squamipinnis, Pimelodus clarias, Pseudoplatystoma corruscans and Salminus hilarii. Scanning electron microscopy micrographies, original figures and measurements of adult and immature specimens from different Brazilian hosts and localities are presented

During investigation on the helminth parasites from Brycon hilarii Valenciennes, 1850 (Characiformes, Characidae), from River Juba, Tangará da Serra, state of Mato Grosso, Brazil, several specimens of the nematode Neocucullanus Travassos, Artigas et Pereira, 1928 were detected. A detailed study of this material, including scanning electron microscopy, allowed to identify these nematodes as N. neocucullanus Travassos, Artigas et Pereira, 1928 and to confirm N. multipapillatus Petter, 1989 as a junior synonym of N. neocucullanus.

The skeletal remains of 17 people buried in the Eaton Ferry Cemetery in northern North Carolina provide a means of examining health and infectious disease experience in the XIX century South. The cemetery appears to contain the remains of African Americans enslaved on the Eaton family estate from approximately 1830-1850, and thus offers a window into the biological impacts of North American slavery in the years preceding the Civil War. The sample includes the remains of six infants, one child, and one young and nine mature adults (five men, four women, and one unknown). Skeletal indices used to characterize health and disease in the Eaton Ferry sample include dental caries, antemortem tooth loss, enamel hypoplasia, porotic hyperostosis, periosteal lesions, lytic lesions, and stature. These indicators reveal a cumulative picture of compromised health, including high rates of dental disease, childhood growth disruption, and infectious disease. Specific diseases identified in the sample include tuberculosis and congenital syphilis. Findings support previous research on the health impacts of slavery, which has shown that infants and children were the most negatively impacted segment of the enslaved African American population.

Switzerland appears to be a privileged place to investigate the urban political ecology of tap water because of the specificities of its political culture and organization and the relative abundance of drinking water in the country. In this paper, we refer to a Foucauldian theorization of power that is increasingly employed in the social sciences, including in human geography and political ecology. We also implement a Foucauldian methodology. In particular, we propose an archaeo-genealogical analysis of discourse to apprehend the links between urban water and the forms of governmentality in Switzerland between 1850 and 1950. Results show that two forms of governmentality, namely biopower and neoliberal governmentality, were present in the water sector in the selected period. Nonetheless, they deviate from the models proposed by Foucault, as their periodization and the classification of the technologies of power related to them prove to be much more blurred than Foucault's work, mainly based on France, might have suggested.
