Serrasentis sagittifer (Linton, 1889) (Acanthocephala)

Dans le travail présent, Serrasentis sagittifer est redécrit et la validité du nom et des espèces qui lui sont assimilées est discutée.

Quatro especies nuevas de nematodos del sur del Perú y redescripción de Hedruris Orestiae Moniez, 1889

En el estudio helmintológico de anfibios del género Telmatobius Wiegmann, 1834, y del pez Orestias luteus Valenciennes, 1839, de las zonas de Arequipa, Puno y del Lago Titicaca, se han encontrado nematodes de los géneros Hedruris Nitzsch, 1821 y Falcaustra Lane, 1915. Se redescribe Hedruris orestiae Moniez, 1889 y se describen cuatro especies nuevas: Hedruris moniezi sp. n., Falcaustra condorcanquii sp. n., Falcaustra pumacahuai sp. n. y Falcaustra tiahuanaquensis sp. n.

Maritremopsis mariettavogeae sp. n. (Trematoda, Microphallidae) and Amphimerus lancea (Diesing, 1850) (Trematoda, Opisthorchiidae) parasites of Nectomys Squamipes (Rodenta) in Brazil

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.

What is paragonimus rudis (diesing, 1850)?: report on a field study in Mato Grosso, Brazil

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.

Estudo das espécies brasileiras do genêro Diplotriaena Henry & Ozoux, 1909 (Nematoda, Filarioidea)

Vinte espécies do gênero Diplotriaena Henry & Ozoux, 1909 que ocorrem no Brasil, foram estudadas. A taxonomia desse grupo de nematódeos parasitos de aves é baseada na forma e tamanho dos tridentes e espículos. Para todas as espécies forma registradas suas dimensões, hospedeiros e distribuição regional, através de tabelas comparativas. Comentários a respeito de algumas espécies foram feitos, de modo a fornecer dados adicionais. É também apersentada uma chave para a determinação das espécies.

Lampas y el espíritu de la naturaleza: estudio de la controversia entre Henry More y Robert Hooke

“Lampas y el Espíritu de la Naturaleza” estudia la controvèrsia entre Henry More i Robert Hooke a propòsit de la filosofia mecànica de la naturalesa en el context del pensament filosòfic i científic del segle XVII a Anglaterra, una controvèrsia que malgrat que es pugui considerar obsoleta en la seva forma no ho és en el seu fons, ja que tant les qüestions plantejades per More com les observacions de Hooke són pertinents i no són lluny, mutatis mutandis, de determinats plantejaments del nostre present.

El Real Conservatorio de Artes (1824-1850): Orígenes y gestación de la ingeniería industrial moderna

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.

Redescrição de Pterobothrium crassicolle Diesing, 1850 (Cestoda: Trypanorhyncha) e revalidação da espécie

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 and future well-being in Germany, 1850-2000

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.
