Morfometria dos forames mandibular, mentual e infraorbital de Lobo-guará Chrysocyon brachyurus, Illiger, 1815 aplicada a bloqueios anestésicos

CHAPTER II - The Chrysocyon brachyurus is the biggest South American canid which has a high frequency of dental injuries, both in wild and captivity. Thus, veterinary procedures are necessary to preserve the feeding capacity of hundreds of captive specimens worldwide. The aim of this study was to study the mandibular morphometry of maned wolf with emphasis on the establishment of anatomic references to the anesthetic blockage of the inferior alveolar and mental nerves. Therefore, 15 measurements in 22 hemimandibles of C. brachyurus adults were taken. For extra-oral technique of blockage of the inferior alveolar nerve at the level of the mandibular foramen, it is stated that the needle should be advanced, close to the medial surface of the mandibular ramus, by 11.4 mm perpendiculary from the palpable concavity. Alternatively, the needle can be introduced for 30.4 mm from the angular process at 20-25 degrees angle with the ventral margin. For blocking only the mentual nerve, it is recommended the introduction of needle for 10 mm, close to the lateral aspect of the mandibular body, at the level of the lower first premolar. The mandibular foramen showed similars position, size and symmetry in the maned wolfs specimens examined. The comparison of the data with those available for other carnivores reflects the necessity for determining these anatomical references specifically for each species.

Los costos de la expedición militar a Chile, 1815-1818

Este trabajo explora las estrategias utilizadas para financiar la creación y el sostenimiento del Ejército de los Andes y los instrumentos fiscales utilizados para conseguirlo. El análisis de los distintos rubros que integraban las cajas del ejército permite examinar el peso de los recursos aportados por el gobierno central y por la jurisdicción cuyana. Asimismo, analiza el destino de los fondos a través del estudio de los presupuestos del ejército, con el objetivo de ponderar el peso que tuvieron los salarios en el total de los gastos militares durante la etapa previa al cruce de los Andes, y en la posterior, cuando el ejército estaba en Chile bajo severas condiciones fiscales de los gobiernos patriotas.

Aerial line transect survey to estimate abundance of marsh deer (Blastocerus dichotomus) (Illiger, 1815)

A população de cervo-do-pantanal (Blastocerus dichotomus) está drasticamente reduzida no Brasil. O nosso objetivo foi o de estimar a abundância do cervo-do-pantanal na bacia do Rio Paraná e discutir a metodologia aplicada. Os resultados darão suporte para uma análise do impacto do enchimento da represa de Porto Primavera sobre essa população. Sessenta e nove animais foram registrados através de sobrevôo utilizando-se a metodologia de transecção linear com amostragem das distâncias. Os dados não corrigidos resultaram em uma densidade estimada de 0,0035ind/ha e uma população de 636 indivíduos. A correção de g para os animais que não foram vistos apresentou uma densidade de 0,0049 ind/ha e uma abundância de 896 (CV=0,27) indivíduos. A metodologia foi aplicada com sucesso na estimativa de cervo-do-pantanal. Esse resultado é importante para avaliarmos a população do cervo-do-pantanal na área e para futuramente analisarmos o impacto do enchimento da represa.

Eugenio de Ochoa (1815-1872). El hombre de letras en la España de Isabel II

El nombre de Eugenio de Ochoa siempre aparece en los libros sobre la cultura española del siglo XIX, aunque pocas veces con un papel protagonista. Su lugar en la historia de la literatura se halla asociado a otros personajes o a empresas periodísticas de importancia que son recordadas por los nombres de esos otros: El Artista, Federico Madrazo, Pedro Madrazo, Juan Eugenio Hartzenbusch, Victor Hugo, Balzac… Y así Ochoa es siempre el co-creador de una revista, el cuñado de, el amigo de, el traductor de, el editor de… Esta posición secundaria ha restado atractivo al estudio de un hombre que desempeñó un papel fundamental en la conexión de la cultura española con Europa, tanto por ser el vehículo por el que llegaron a España muchos autores contemporáneos como por llevar a cabo el recorrido contrario, mostrando al continente el patrimonio cultural nacional. Sin embargo, esa faceta de intermediario, y no la de literato, contemplada desde una perspectiva más centrada en el contexto y menos en el canon literario tradicional, ofrece unas posibilidades de análisis extremadamente interesantes. Además, la gran pluralidad de sus actividades le convirtió en su tiempo en un observador privilegiado de la realidad cultural y política del país. Ahí se halla el objetivo que ha guiado la realización de este trabajo. Por medio del estudio de su figura se ha pretendido llevar a cabo un análisis de la cultura española del siglo XIX, partiendo de un enfoque sociológico de la misma y prestando más atención a las prácticas en el campo literario que al contenido de la creación. Esa es la razón que explica que, metodológicamente, el trabajo se apoye en dos pilares, cada uno de los cuales sirve de soporte a las dos partes centrales del mismo: la reflexión acerca del “hombre de letras” en el reinado de Isabel II y el papel desempeñado por el mediador cultural en el proceso de transferencia de conocimientos e imágenes nacionales en la Europa del siglo XIX. Al comienzo de cada uno de estos bloques se realiza una reflexión más detallada sobre ambas líneas de análisis que, por supuesto, no son las únicas y no agotan el tema...

Molecular Systematics and Traits Evolution in Phasmatodea Leach, 1815 (Hexapoda; Insecta)

Phasmatodea Leach, 1815 (Hexapoda; Insecta) is a polyneopteran order which counts approximately 3000 described species, often known for their remarkable forms of mimicry. In this thesis, I provide a comprehensive systematic framework which includes over 180 species never considered in a phylogenetic framework: the latter can facilitate a better understanding of the processes underlying phasmids evolutionary history. The clade represents in fact an incredible testing ground to study trait evolution and its striking disparity of reproductive strategies and wing morphologies have been of great interest to the evolutionary biology community. Phasmids wings represent one of the first and most notable rejection of Dollo’s law and they played a central role in initiating a long- standing debate on the irreversibility of complex traits loss. Macroevolutionary analyses presented here confirm that wings evolution in phasmids is a reversible process even when possible biases - such as systematic uncertainty and trait-dependent diversification rates - are considered. These findings remark how complex traits can evolve in a dynamic, reversible manner and imply that their molecular groundplan can be preserved despite its phenotypical absence. This concept has been further tested with phylogenetic and transcriptomic approaches in two phasmids parthenogenetic lineages and a bisexual congeneric of the European Bacillus species complex. Leveraging a gene co-expression network approach, male gonad associated genes were retrieved in the bisexual species and then their modifications in the parthenogens were charachterized. Pleiotropy appears to constrain gene modifications associated to male reproductive structures after their loss in parthenogens, so that the lost trait molecular groundplan can be largely preserved in both transcription patterns and sequence evolution. Overall, the results presented in this thesis contribute to shape our understanding of the interplay between the phenotypic and molecular levels in trait evolution.

The Atomic Structure Of A Bare Buffer Layer On Sic(0001) Chemically Resolved.

A chemical-specific photoelectron diffraction structure determination of a carbon rich buffer layer on SiC is reported. In addition to the long-range ripple of this surface, a local buckling in the hexagonal sublattice, which breaks the local range order symmetry, was unraveled.

Acetatos homo e heterotrinucleares de ferro: um experimento para o laboratório de química de coordenação

Homo and heterotrinuclear acetates are unique compounds having μ3-oxo bridge and many interesting properties of such compounds are derived from this structure. Some undergraduate inorganic textbooks discuss several aspects of these compounds and we present here an undergraduate experiment for the high-yield synthesis of [Fe2MO(CH3CO2)6(H 2O)3], with M = Fe3+, Co2+ and Ni2+, as well as their characterization using infrared spectroscopy and cyclic voltametry. The proposed experiment gives the opportunity to discuss several concepts of coordination chemistry that follow the characterization techniques, such as: types of acetate coordination, reversibility of electrochemical processes, quelate and trans effects and lability.

Status of Early 19th-Century Names Authored in Parallel by Wied and Schinz for South American Reptiles and Amphibians, with Designations of Three Nomina Protecta

Prince Maximilian zu Wied's great exploration of coastal Brazil in 1815-1817 resulted in important collections of reptiles, amphibians, birds, and mammals, many of which were new species later described by Wied himself The bulk of his collection was purchased for the American Museum of Natural History in 1869, although many ""type specimens"" had disappeared earlier. Wied carefully identified his localities but did not designate type specimens or type localities, which are taxonomic concepts that were not yet established. Information and manuscript names on a fraction (17 species) of his Brazilian reptiles and amphibians were transmitted by Wied to Prof. Heinrich Rudolf Schinz at the University of Zurich. Schinz included these species (credited to their discoverer ""Princ. Max."") in the second volume of Das Thierreich ... (1822). Most are junior objective synonyms of names published by Wied. However, six of the 17 names used by Schinz predate Wied's own publications. Three were manuscript names never published by Wied because he determined the species to be previously known. (1) Lacerta vittata Schinz, 1822 (a nomen oblitum) = Lacerta striata sensu Wied (a misidentification, non Linnaeus nec sensu Merrem) = Kentropyx calcarata Spix, 1825, herein qualified as a nomen protectum. (2) Polychrus virescens Schinz, 1822 = Lacerta marmorata Linnaeus, 1758 (now Polychrus marmoratus). (3) Scincus cyanurus Schinz, 1822 (a nomen oblitum) = Gymnophthalmus quadrilineatus sensu Wied (a misidentification, non Linnaeus nec sensu Merrem) = Micrablepharus maximiliani (Reinhardt and Lutken, ""1861"" [1862]), herein qualified as a nomen protectum. Qualifying Scincus cyanurus Schinz, 1822, as a nomen oblitum also removes the problem of homonymy with the later-named Pacific skink Scincus cyanurus Lesson (= Emoia cyanura). The remaining three names used by Schinz are senior objective synonyms that take priority over Wied's names. (4) Bufo cinctus Schinz, 1822, is senior to Bufo cinctus Wied, 1823; both, however, are junior synonyms of Bufo crucifer Wied, 1821 = Chaunus crucifer (Wied). (5) Agama picta Schinz, 1822, is senior to Agama picta Wied, 1823, requiring a change of authorship for this poorly known species, to be known as Enyalius pictus (Schinz). (6) Lacerta cyanomelas Schinz, 1822, predates Teius cyanomelas Wied, 1824 (1822-1831) both nomina oblita. Wied's illustration and description shows cyanomelas as apparently conspecific with the recently described but already well-known Cnemidophorus nativo Rocha et al., 1997, which is the valid name because of its qualification herein as a nomen protectum. The preceding specific name cyanomelas (as corrected in an errata section) is misspelled several ways in different copies of Schinz's original description (""cyanom las,"" ""cyanomlas,"" and cyanom""). Loosening, separation, and final loss of the last three letters of movable type in the printing chase probably accounts for the variant misspellings.
