"La paradisíaca estabilidad de la anteguerra". Elaboración de un índice de precios de consumo de España, 1830-1936.

Este artículo expone los aspectos básicos de la elaboración un nuevo, y auténtico, Índice de Precios de Consumo de España para el período 1830-1936. Los distintos apartados en que está organizado se dedican a definir el campo de observación y el ámbito analizados, las fuentes empleadas y la metodología utilizada, así como las similitudes y diferencias con otros índices actualmente disponibles. Contiene, asimismo, un contiene un primer y breve análisis de los resultados. La característica más sobresaliente desde la perspectiva de las tendencias de largo plazo del nuevo IPC es una gran estabilidad, quebrada de forma importante, tan sólo, durante los años 1914-1920 bajo la influencia de la Primera Guerra Mundial. La tasa de crecimiento para el conjunto del período no alcanzó siquiera el uno por cien anual, pese al cambio de nivel registrado en aquel breve brote inflacionista.

Diseminación de enteroparasitos por Calliphoridae (Insecta, Diptera)

It is establish the dissemination enteroparasite by Calliphoridae in a district situated around by Federal Capital of Argentina. The species implicated in this dispersal are: Phaenicia sericata (meigen, 1826); Calliphora vicina Robineau-Desvoidy, 1830; Chrysomya chloropyga (Wiedemann, 1818) and Phaenicia eximia (Wiedemann, 1819). Fifty two flies was studies, thirty four (65%) to belong at the family Calliphoridae. Of this thirteen (38%) have eggs of taeniid and cysts of Entamoeba coli (Grassi, 1879) and Giardia lamblia Styles, 1915.

Revisão das espécies neotropicais de Ophyra Robineau-Desvoidy, 1830 (Diptera, Muscidae, Azelinae)

Data on the genus Ophyra and on its known neotropical species are presented as well as a key to segregate them.

A critical edition of Joseph Conrad's "Because of the dollars" (Within the Tides, 1915)

Cette thèse de doctorat, écrite en anglais, propose la première édition critique de « Because of the Dollars », une nouvelle de l'écrivain anglais Joseph Conrad publiée dans le volume Within the Tides, en février 1915. Outre le texte critique de la nouvelle - le seul à ce jour reconstruit d'après une minutieuse étude des relations entre toutes les versions existantes - la présente édition offre aussi un vaste apparat éditorial. Le texte de la présente édition est éclectique. Sa ponctuation est essentiellement basée sur un texte proche du manuscrit de l'auteur, et donc non corrompu par le processus de transmission. Mais ses mots sont tirés des dernières versions révisées par l'auteur, étant donné qu'au cours de la transmission, les mots, contrairement aux marques de ponctuation, n'ont pas été contaminés. Le résultat de cette méthode est un texte reflétant, tant pour les mots que pour la ponctuation, les choix de l'auteur. L'apparat éditorial sert à placer la nouvelle dans la vie de Conrad, tracer l'évolution du texte, et offrir au lecteur des informations historiques et culturelles qui permettront une meilleure lecture de l'oeuvre. Cet apparat est composé de quatre parties : une introduction, une étude sur les textes de la nouvelle, une collation historique de toutes les variantes, et des notes explicatives. L'introduction place l'oeuvre dans le contexte de la vie de l'écrivain, en donne la réception critique de 1915 à nos jours, et en éclaire le contexte historique (un changement de monnaie à Singapour en 1903-4). L'étude sur les textes trace le développement et la transmission du texte, depuis son inscription sur pages manuscrites jusqu'à sa publication dans les oeuvres complètes de Conrad. La collation historique inventorie toutes les variantes textuelles entre les différentes versions existantes. Enfin, les notes explicatives glosent les allusions littéraires, historiques, et culturelles du texte. « Because of the Dollars » et Within the Tides n'ayant attiré que très peu d'attention critique, les informations contenues dans cet apparat éditorial sont complètement inédites, et jettent une lumière originale sur une période peu étudiée de la vie de Conrad.

Comparison of the reproductive behavior between isolated Peckia chrysostoma (Wiedemann, 1830) and Adiscochaeta ingens (Walker, 1849) (Diptera: Sarcophagidae) females reared in laboratory

In both species, maintained under laboratory environmental conditions, anautogeny was comproved and all females that had free access to proteic source were fertiles. We obtained the following average values for Peckiachrysostoma: 59.7 ± 15.6 and 81.8 ± 15.4 days of longevity in the respective cases of free access and no access to proteic source, 21.4 ± 4.3 days of pre-larviposition period and 35.2 ± 16.5 days of larviposition period, 5.3 ± 1.8 larvipositions female with 7.0 ± 1.1 days of periodicity, 35.7 ± 6.1 larvae per larviposition leading to a total number of 183.8 ± 69.2 viable larvae per female and 94.8% ± 5.3% of productivity. The mean number of ovarioles per female was 56.4 ± 9.8, resulting in a reproductive potential of 63.3%. For Adiscochaeta ingens, the obtained average values were: 41.3 ± 6.3 and 52 ± 13.1 days of longevity in the respective cases of free access and no access to proteic source, 15.3 ± 1.7 days of pre-larviposition period and 21.5 ± 7.5 days of larviposition period, 3 ± 0.7 larvipositions per female with 10.4 ± 0.8 days of periodicity, 30.3 ± 8.2 larvae per larviposition leading to a total number of 78.5 ± 21.7 viable larvae per female and 90.1% ± 16% of productivity. The mean number of ovarioles per female was 54.6 ± 5.2, resulting in a reproductive potential of 55.5%. Within applied parameters, the values obtained for P. chrysostoma demonstrate its superior productivity in comparison with A. ingens

Desenvolvimento Pós-embrionário de Ophyra aenescens (Wiedemann, 1830) (Diptera: Muscidae) em Diferentes Dietas, sob Condições de Laboratório

Post-embryonic Development of Ophyra aenescens (Wiedemann, 1830) (Diptera: Muscidae), in Different Diets, under Laboratory Conditions - The performance of various diets (bovine meat, fish- sardine, shrimp, dog faeces, and banana) in Ophyra aenescens development was evaluated. The biology was studied in an incubator (BOD) at 27±1oC and 80±10% of RH. The developmental time from larvae to adult, the developmental time and viability of larvae and pupae, the weight of pupae as well as the sex ratio of the emerging adults were also determined. Beef and shrimp were the more efficient diets for rearing O. aenescens.

Intestinal fibrovascular nodules caused by Schistosoma mansoni infection in Calomys callosus Rengger, 1830 (Rodentia: Cricetidae): a model of concomitant fibrosis and angiogenesis

Human schistosomiasis develops extensive and dense fibrosis in portal space, together with congested new blood vessels. This study demonstrates that Calomys callosus infected with Schistosoma mansoni also develops fibrovascular lesions, which are found in intestinal subserosa. Animals were percutaneously infected with 70 cercariae and necropsied at 42, 45, 55, 80, 90 and 160 days after infection. Intestinal sections were stained for brightfield, polarization microscopy, confocal laser scanning, transmission and scanning electron microscopies. Immunohistological analysis was also performed and some nodules were aseptically collected for cell culture. Numerous intestinal nodules, appearing from 55 up to 160 days after infection, were localized at the interface between external muscular layer and intestinal serosa, consisting of fibrovascular tissue forming a shell about central granuloma(s). Intranodular new vessels were derived from the vasculature of the external vascular layer and were positive for laminin, chondroitin-sulfate, smooth muscle alpha-actin and FVIII-RA. Fibroblastic cells and extracellular matrix components (collagens I, III and VI, fibronectin and tenascin) comprised the stroma. Intermixed with the fibroblasts and vessels there were variable number of eosinophils, macrophages and haemorrhagic foci. In conclusion, the nodules constitute an excellent and accessible model to study fibrogenesis and angiogenesis, dependent on S. mansoni eggs. The fibrogenic activity is fibroblastic and not myofibroblastic-dependent. The angiogenesis is so prominent that causes haemorrhagic ascites.

Infectious disease among enslaved African Americans at Eaton's Estate, Warren County, North Carolina, ca. 1830-1850

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.
