En este trabajo me propongo analizar la influencia de la revolución de Haití en las independencias de Venezuela y Colombia durante los años 1804-1825. Miintención es demostrar que las repercusiones del proceso haitiano fueron vastas, complejas y sufrieron importantes cambios durante el transcurso de los años. En líneas generales, la revolución generó pánico entre las elites criollas y peninsulares y esperanzas entre grupos de esclavos y pardos. Inicialmente los sectores criollos revolucionarios buscaron evitar todo contacto con la isla y eludir el modelo insurgente haitiano por considerar que produciría en la Tierra Firme una "guerra de razas" y una hecatombe similar a la que, en su opinión, allí había acontecido. Sin embargo, a partir de 1812-1813 debido a las dificultades de la guerra de independencia una fracción de la elite criolla comenzó a estrechar vínculos con la República del Sur de Haití a través de contactos diplomáticos y corsarios. Estas primeras relaciones, más bien tímidas, fueron la condición de posibilidad de un cambio importante que sobrevino en 1816. En dicho año, debido a la reconquista de la expedición realista, la mayoría de los líderes independentistas huyeron de Tierra Firme y tuvieron que exiliarse en Haití, uno de los pocos lugares donde encontraron refugio y apoyo. En aquel contexto, se dio el pacto entre Alexandre Petión y Simón Bolívar, por el cual el primero se comprometió a aportar armas, barcos y hombres a la causa patriota a cambio de la emancipación de los esclavos hispanoamericanos. Este acuerdo fue fundamental ya que no sólo posibilitó la exitosa contraofensiva independentista, sino que además le dio un cariz social al proceso revolucionario de Venezuela y Colombia. Así, a partir de 1816 y hasta 1821, se dieron numerosos contactos e incluso el gobierno de Jean Pierre Boyer (sucesor de Alexandre Petión) colaboró con otras dos expediciones a cargo de Gregor Mac Gregor para liberar Panamá y Río Hacha. Sin embargo, el cambio no fue total y aún durante estos años, los líderes criollos continuaron teniendo reparos frente al peligro de la explosión de un nuevo Haití en la Tierra Firme hispana. Por último, el fin de la guerra de independencia abrió un nuevo contexto en el cual aquellos miedos se intensificaron debido a la movilización social interna. Esto derivó en nuevo alejamiento y el gobierno de Colombia no sólo se negó a mantener relaciones con Haití, sino que incluso lo excluyó del Congreso de Panamá.

Factors influencing the rate of cannibalism in juvenile blue-swimmer crabs Portunus pelagicus were investigated under controlled conditions using time-lapse video recordings. This study was undertaken to improve blue-swimmer crab culture and experimentally addressed (1) prey vulnerability (2) cannibal-victim interactions, and (3) activity patterns of juveniles in varying degrees of refuge. Crabs used in the study were aged 15 weeks and sorted into two size classes; small (less than or equal to 60 mm carapace width (CW)) and large (greater than or equal to65 mm CW) of a similar sex ratio. Vulnerability and thus survival was influenced by body size variation, moult stage and refuge availability. Crabs with carapace width less than or equal to 60 mm were more vulnerable than larger individuals, as indicated by significant differences in survival rates. As predicted, juveniles in transition stages associated with ecdysis were especially vulnerable. Premoult (redliner) crabs appeared to be in a high state of agitation as evidenced by the frequency of agonistic encounters and this may be a contributing factor to the high mortality observed at this critical premoult stag. increases in refuge density increased survival of juveniles proportionally, indicating that the quantity of shelter is important for reducing cannibalism in this species. Cannibal-victim interactions were frequently asymmetrical in terms of size and moult stage. Cannibals were significantly heavier than victims, and were predominantly at intermoult stage. Sexual biases among cannibals and victims were not found in this study. Activity patterns of juveniles were influenced by the experimental conditions. Crabs provided with high refuge showed reduced aggressive activity and increased time spent resting, but unchanged locomotion or feeding activity. Regular grading as well as the presence of suitable shelter for newly moulted crabs is recommended for improving culture of P. pelagicus. Research into inducing synchronous moulting may also yield promising results. (C) 2004 Elsevier B.V. All rights reserved.

Sarah Poulton Kalley é conhecida, em quase todos os segmentos do protestantismo do Brasil, devido à organização e compilação d e Salmos e Hinos, o mais antigo hinário protestante editado no vernáculo em nosso país. Seus hinos, ainda em uso em muitas igrejas, marcaram por mais de um século a teologia do protestantismo no Brasil. Apesar desta notoriedade, sua influência na gênese do protestantismo brasileiro nunca foi objeto de estudo. Assim, o objetivo desta pesquisa é resgatar e visibilizar áreas e estratégias de atuação que conferem a esta mulher um perfil de atuação relativamente autônomo. Contudo, centrada no estudo da trajetória intelectual e biográfica de um sujeito histórico, a investigação se defronta com um universo de personagens anônimos, envoltos numa complexa teia de relações, através das quais o protestantismo se insere no Brasil em um contexto especifico: huguenotes, puritanos, luddistas, famílias não-conformistas inglesas, líderes políticos e eclesiásticos, exilados madeirenses, brasileiros, portugueses, imigrantes alemães e, principalmente, a mulher protestante brasileira. A busca por informações sobre este universo relegado ao anonimato pela historiografia do protestantismo no Brasil, reve lou alguns documentos inéditos, inclusive um livro escrito por Sarah Poulton Kalley, em 1866: o A Alegria da Casa. Muito além do papel de esposa de um missionário e médico, Sarah Poulton Kalley emerge de uma rede de relações e práticas como professora, missionária e poetisa. Nestes três campos de atuação e através do desenvolvimento de múltiplos contatos e relacionamentos, procurava transformar e influenciar atitudes e crenças de seus interlocutores. Junto com a nova fé divulgava uma cosmovisão própria da cultura anglo-saxã, protestante e puritana, adaptando-a seletivamente ao universo cultural e social de seus interlocutores.(AU)

Approaches to quantify the organic carbon accumulation on a global scale generally do not consider the small-scale variability of sedimentary and oceanographic boundary conditions along continental margins. In this study, we present a new approach to regionalize the total organic carbon (TOC) content in surface sediments (<5 cm sediment depth). It is based on a compilation of more than 5500 single measurements from various sources. Global TOC distribution was determined by the application of a combined qualitative and quantitative-geostatistical method. Overall, 33 benthic TOC-based provinces were defined and used to process the global distribution pattern of the TOC content in surface sediments in a 1°x1° grid resolution. Regional dependencies of data points within each single province are expressed by modeled semi-variograms. Measured and estimated TOC values show good correlation, emphasizing the reasonable applicability of the method. The accumulation of organic carbon in marine surface sediments is a key parameter in the control of mineralization processes and the material exchange between the sediment and the ocean water. Our approach will help to improve global budgets of nutrient and carbon cycles.

The dog-eating fox (Cerdocyon thous - Linnaeus, 1766) is a medium sized canid widely distributed in South America and occurs in almost all of Brazil. Among the main threats to their conservation are the roadkill mainly caused by habitat loss. The shortage of laboratory bush dogs data affect the veterinary medical care hindering the application of appropriate therapies. This study aimed to evaluate the levels of C-reactive protein, albumin, pre-albumin, ceruloplasmin, haptoglobin and Afla 1 acid glycoprotein and the Prognostic Index Inflammatory Nutritional (IPIN) in this species, thus obtaining a first description of these prognostic markers. They collected 1.5 ml of blood by jugular access 8 of Mato Dogs copies (thous thous) from the Laboratory of collection of Teaching and Research in Wildlife (limpets), Faculty of Veterinary Medicine, Federal University of Uberlândia for exams routine. The samples were collected via the jugular vein after physical restraint of animals and trichotomy of the region. After statistical analysis, the values were: albumin: between 2.7 and 3.0 g / dl, alpha 1-acid glycoprotein: between 0.19 and 0.21 g / l, C-reactive protein: between 1.7 and 2 2, prealbumin between 30 and 35 mg / l haptoglobin: between 0.078 and 0.156 and IPIN ≤ 0.006 being considered normal and values ≥ 0.006 considered high. This press description will serve as a basis for studies where animals may be used with specific diseases and, after analysis, compared with the values found in this study and verified the behavior follows the likeness of domestic dogs.

The objective of this research is to study the origin of the lumbosacral plexus and its nerves in coatis (Nasua nasua). Six adult specimens, three males and three females, were used in this research. The animals were donated by IBAMA / GO or were collected when found dead by the edges of highways in Southeast Goiás. The specimens were fixed in aqueous 10% formaldehyde solution and preserved in the same solution. The observations reveal that the lumbosacral plexus of the coati has a structure with few intercommunications between its components. There are no typical handle formations, but the roots or its branches converge to form the nerves that are driven to the pelvic limb. The components of the Lumbosacral Plexus are ventral branches of L4 to S3. The Lumbosacral plexus generates several short nerves destined to pelvic structures and, at the same time, three long nerves: femoral, obturator and sciatic, all destined to the hind limb.
