Relaciones interétnicas en el Fuerte San José (Patagonia, siglo XVIII). Una aproximación comparativa

El presente trabajo tiene por objeto presentar la primera aproximación a las relaciones interétnicas en el escenario del Fuerte San José y el Puesto de la Fuente, desde una perspectiva histórica y arqueológica. En particular, presentaremos los primeros resultados de las investigaciones históricas respecto de la problemática mencionada, sobre la base de información inédita analizada hasta el momento. Para ello nos centraremos en los primeros diez años de vida en el Fuerte (1779-1789) y estableceremos una comparación con los otros dos asentamientos que formaron parte del plan de poblamiento español de las costa patagónica (siglo XVIII): el Fuerte Nuestra Señora del Carmen y la Nueva Colonia de Floridablanca, a los efectos de destacar la particularidad del Fuerte San José en el marco de la variabilidad de la estructuración de las relaciones interétnicas en las colonias patagónicas.

Eighty years 'Owre the Sea': Robert Burns and the early United States of America, c. 1786-1866.

This thesis represents the first extensive critical study of the relationship between Robert Burns and the early United States of America. Spanning literature, history and memory studies, the following chapters take an interdisciplinary approach towards investigating the methods by which Burns and his works rose to prominence and came to be of cultural and literary significance in America. Theoretically, these converging disciplines intersect through a transnational, Atlantic Studies perspective that shifts emphasis from Burns as the 'national poet of Scotland' onto the various socio-cultural connections that facilitated the spread of his work and reputation. In addition to Scottish literary studies, the thesis contributes to the broader fields of Transatlantic, Transnational and American Studies. Previous studies have suggested that Burns's popularity in the early United States might be attributed to his kinship with 'national' American ideals of freedom, egalitarianism and individual liberty. While some of the evidence supports this claim, this thesis argues that it also wrongly assumes a spatiotemporal unity for the nineteenth-century American nation. It concludes by suggesting that future critical studies of the poet must heed the multifarious complexities of 'national' paradigms, pointing the way to further work on the reception and influence of Burns in other 'global' or, indeed, transnational contexts.

Biologia reprodutiva da Tainha, Mugil curema valenciennes, 1836 (osteichthyes: mugilidade) nas águas costeiras do Rio Grande do Norte

The marine fish white mullet, Mugil curema Valenciennes, 1836 (Osteichthyes: Mugilidae) exhibits a wide geographical distribution, being common in the Brazilian coast and is an important component of the artisanal fisheries. The objective of this study was to investigate the reproductive biology of M. curema in the coastal waters of Rio Grande do Norte. Fish samples were captured on a monthly basis during August, 2008 to July, 2009. The fish specimens were numbered, weighed, measured, dissected and their gonads were removed, weighed, their sex and gonadal development were identified. The length-weight relationship was determined for males and females. The sex ratio, the size at first gonadal maturation and gonadosomatic index (GSI) were calculated and ovarian development was investigated using macroscopic and histological techniques. The fecundity, spawning type and the reproductive period of the species were determined. A total of 366 specimens (186 males and 180 females) were captured. The sex ratio was 1:1 and the females were heavier than males. The estimated values of the angular coefficient for both sexes suggest that the species has isometric growth. The size at which 50% of the population began the process of maturation was 25.9 cm of total length for grouped sex. The macroscopic characteristics of the ovaries showed four stages of development: immature, maturing, mature and spent. However, the microscopic characteristics of the ovaries showed five stages of development: immature, early maturing, late maturing, mature and spent. The development of oocytes indicated five phases: Chromatin-nucleolus (phase I), initial perinucleolar (phase II), final perinuclear (phase II), formation of vitelline vesicle or yolk (phase III), vitellogenic (phase IV) and complete vitellogenesis (phase V). The species has a prolonged spawning period, with two peaks coinciding with the rainy season.

Scrittura, sociabilità e strategie di persuasione: Marie-Anne Paulze-Lavoisier, secrétaire (1758-1836)

Attraverso uno studio di caso, centrato su Marie-Anne Paulze-Lavoisier (1758-1836), la tesi tratta di pratiche legate all’annotazione e, più in generale, alla registrazione di informazioni su supporti cartacei tra gli anni ’70 del Settecento e gli anni ‘30 dell’Ottocento. Nota oggi come moglie e collaboratrice del chimico Antoine-Laurent Lavoisier (1743-1794), di cui avrebbe promosso le teorie attraverso un’attività di traduttrice e illustratrice, Paulze-Lavoisier è qui presentata nella veste di “secrétaire”, ossia di figura incaricata di mettere per iscritto osservazioni di varia natura. Ci si concentra, in particolare, sui Registres de laboratoire di Lavoisier, 14 quaderni petit in-folio a cui sono affidati i resoconti di esperimenti condotti a Parigi tra il 1772 e il 1788 e che rilevano in misura significativa della mano di lei. Oggetto finora di una storia del pensiero scientifico, interessata alle “idee” in essi contenute, i Registres sono da noi riletti alla luce di un approccio “materiale”, attento alle pratiche e alle condizioni della loro compilazione e del loro riutilizzo nel tempo. Si indagano quindi le funzioni di questi quaderni rispetto alla pratica sperimentale, ricostruendo al contempo i tratti e le evoluzioni del ruolo di segretaria affidato a Paulze-Lavoisier. Il focus su Paulze-Lavoisier permette da un lato a sollevare nuove domande in merito al rapporto tra scrittura delle note, genere e sociabilità ma anche, ad un altro livello, alla cosiddetta “invisibilità” degli assistenti; dall’altro offre la materia per una storia lunga dei Registres, che dai primi gesti in essi da lei operati agli inizi degli anni ’70 del Settecento arriva fino alle manipolazioni a cui sono sottoposti, per sua volontà, nei primi decenni dell’Ottocento.

Analytical procedures for determining Pb and Sr isotopic compositions in water samples by ID-TIMS

Few articles deal with lead and strontium isotopic analysis of water samples. The aim of this study was to define the chemical procedures for Pb and Sr isotopic analyses of groundwater samples from an urban sedimentary aquifer. Thirty lead and fourteen strontium isotopic analyses were performed to test different analytical procedures. Pb and Sr isotopic ratios as well as Sr concentration did not vary using different chemical procedures. However, the Pb concentrations were very dependent on the different procedures. Therefore, the choice of the best analytical procedure was based on the Pb results, which indicated a higher reproducibility from samples that had been filtered and acidified before the evaporation, had their residues totally dissolved, and were purified by ion chromatography using the Biorad® column. Our results showed no changes in Pb ratios with the storage time.

Cladistic analysis of Hemirhipini with establishment of Propalaus gen. nov. (Coleoptera, Elateridae, agrypninae)

This article includes a cladistic analysis of the tribe Hemirhipini. Are included 20 Hemirhipini genera (sensu Casari-Chen 1994), Saltamartinus Casari (1996b) (Hemirhipini), 6 genera excluded from Hemirhipini and kept in Agrypninae (formerly Pyrophorinae) (Casari-Chen 1993) and also, Aphileus Candèze (1857), Pyrophorus Billberg (1820) and Thoramus Sharp (1877). The type-species of the majority of genera and all species of the American genera (except Saltamartinus viduus (Chevrolat 1867)) are included. This analysis demonstrates that 30 genera belong to Hemirhipini: Abiphis Fleutiaux (1926), Alaolacon Candèze (1865), Alaomorphus Hauser (1900), Alaus Eschscholtz (1829), Aliteus Candèze (1857), Anthracalaus Fairmaire (1888), Aphileus Candèze (1857), Austrocalais Neboiss (1967), Calais Castelnau (1836), Catelanus Fleutiaux (1942), Chalcolepidius Eschscholtz (1829), Chalcolepis Candèze (1857), Conobajulus Van Zwaluwenburg (1940), Coryleus Fleutiaux (1942), Cryptalaus Ôhira (1967), Eleuphemus Hyslop (1921), Eumoeus Candèze (1874), Fusimorphus Fleutiaux (1942), Hemirhipus Latreille (1829), Lacais Fleutiaux (1942), Lycoreus Candèze (1857), Mocquerysia Fleutiaux (1899), Neocalais Girard (1971), Pherhimius Fleutiaux (1942), Phibisa Fleutiaux (1942), Propalaus gen. nov., Pseudocalais Girard (1971), Saltamartinus Casari (1996), Tetrigus Candèze (1857) and Thoramus Sharp (1877). The species included in Alaus do not make a monophyletic group and Propalaus gen. nov. is established to include Alaus alicii (Pjatakowa 1941) and A. haroldi (Candèze 1878). A description of Propalaus gen. nov. (type-species: Chalcolepidius haroldi Candèze, 1878) and a new key to Hemirhipini genera are also presented.

Anabolic steroid associated to physical training induces deleterious cardiac effects

DO CARMO, E. C., T. FERNANDES, D. KOIKE, N. D. DA SILVA JR., K. C. MATTOS, K. T. ROSA, D. BARRETTI, S. F. S. MELO, R. B. WICHI, M. C. C. IRIGOYEN, and E. M. DE OLIVEIRA. Anabolic Steroid Associated to Physical Training Induces Deleterious Cardiac Effects. Med. Sci. Sports Exerc., Vol. 43, No. 10, pp. 1836-1848, 2011. Purpose: Cardiac aldosterone might be involved in the deleterious effects of nandrolone decanoate (ND) on the heart. Therefore, we investigated the involvement of cardiac aldosterone, by the pharmacological block of AT1 or mineralocorticoid receptors, on cardiac hypertrophy and fibrosis. Methods: Male Wistar rats were randomized into eight groups (n = 14 per group): Control (C), nandrolone decanoate (ND), trained (T), trained ND (TND), ND + losartan (ND + L), trained ND + losartan (TND + L), ND + spironolactone (ND + S), and trained ND + spironolactone (TND + S). ND (10 mg.kg(-1).wk(-1)) was administered during 10 wk of swimming training (five times per week). Losartan (20 mg.kg(-1).d(-1)) and spironolactone (10 mg.kg(-1).d(-1)) were administered in drinking water. Results: Cardiac hypertrophy was increased 10% by using ND and 17% by ND plus training (P < 0.05). In both groups, there was an increase in the collagen volumetric fraction (CVF) and cardiac collagen type III expression (P < 0.05). The ND treatment increased left ventricle-angiotensin-converting enzyme I activity, AT1 receptor expression, aldosterone synthase (CYP11B2), and 11-beta hydroxysteroid dehydrogenase 2 (11 beta-HSD2) gene expression and inflammatory markers, TGF beta and osteopontin. Both losartan and spironolactone inhibited the increase of CVF and collagen type III. In addition, both treatments inhibited the increase in left ventricle-angiotensin-converting enzyme I activity, CYP11B2, 11 beta-HSD2, TGF beta, and osteopontin induced by the ND treatment. Conclusions: We believe this is the first study to show the effects of ND on cardiac aldosterone. Our results suggest that these effects may be associated to TGF beta and osteopontin. Thus, we conclude that the cardiac aldosterone has an important role on the deleterious effects on the heart induced by ND.

A positive growth response to NaCl applications in Eucalyptus plantations established on K-deficient soils

Contrasting responses of Eucalyptus trees to K fertilizer applications have been reported on soils with low K contents. A complete randomized block experiment was set up in Brazil to test the hypothesis that large atmospheric deposits of NaCl in coastal regions might lead to a partial substitution of K by Na in Eucalyptus physiology and enhance tree growth. Treatments with application of 1.5, 3.0, 4.5 kmol K ha(-1) (K(1.5), K(3.0), 1(4.5, respectively) as KCl, 3.0 kmol K ha(-1) applied as K(2)SO(4), 3.0 kmol Na ha(-1) (Na(3.0)) as NaCl commercialized for cattle feeding, and a mixture of 1.5 kmol K + 1.5 kmol Na ha(-1) (K(1.5) + Na(1.5)) were compared to a control treatment (C) with no K and Na applications. All the plots were fertilized with large amounts of the other nutrients. A positive effect of NaCl applications on the growth of E. grandis trees was observed. NaCl and KCl additions in treatments Na(3.0) and K(3.0) increased above-ground biomass by 56% and 130% three years after planting, respectively, in comparison with the C treatment. By contrast, accumulated litterfall up to age 3 years was not significantly modified. NaCl applications in the Na(3.0) treatment significantly increased Na accumulation in above-ground tree components but did not modify K accumulation, whatever the sampling age. A partial substitution of K by Na in tree physiology, as observed for various agricultural crops, might explain this behaviour. Our results suggest the possibility of applying inexpensive K fertilizers, which are less purified in Na, and explain why high yields are achieved without K fertilizer applications in areas with large dry depositions of marine aerosols. Further investigations are necessary to identify the processes involving Na in Eucalyptus tree physiology. (C) 2009 Elsevier B.V. All rights reserved.
