A documentary contribution to the cultural history: transcription of the annual ordinary functions of the cathedral cordobesa in the 19th century

Parte de un trabajo de Fin de Máster dedicado al estudio del ceremonial religioso catedralicio cordobés en el siglo XIX, donde se observaba su parafernalia, desde la participación de la jerarquía eclesiástica (cabildo e instituciones civiles) que asisten y que son el centro de atención de la procesión, hasta su modo de presentación pública, según tiempos litúrgicos, la presente transcripción documental se centra en un grupo de ese amplio conjunto de ceremonias litúrgicas analizadas en su momento: las funciones anuales ordinarias. Elegidas porque también sus diversos contenidos llevan consigo la autoafirmación del poder eclesiástico decimonónico y su singular influencia en la sociedad de la época, su publicación pretende ser apoyo heurístico a la investigación de uno de los ejes más significativos de la nueva Historia Cultural.Part of a Masters End of work devoted to the study of religious ceremonial Cordoba cathedral in the nineteenth century, where he watched his paraphernalia, from involvement of the hierarchy (chapter and civil institutions) who attend and are the focus of the procession to their mode of public presentation, as liturgical, this transcript documentary focuses on a group this large range of religious ceremonies in their time tested: regular annual features. Chosen because its various content carry the nineteenth-century self-assertion of ecclesiastical power and its unique influence on society of the time, its publication is intended to be heuristic support to the investigation of one of the most significant axes of the new cultural history

Estudio comparativo in vitro de la resistencia a la tracción y compresión en restauraciones estandarizadas realizadas conresinas compuestas v/s vidrio ionómero de alta densidad en dientes temporales

Tesis (Cirujano Dentista)Actualmente la odontología pediátrica tiene un enfoque orientado principalmente a la promoción de la salud oral y prevención de enfermedades orales prevalentes en niños. La enfermedad bucal más prevalente en la población infantil es la caries dental, la cual está directamente relacionada con factores de riesgo tales como la dieta, biofilm, factores salivales, exposición al flúor, factores conductuales, estructura dentaria y experiencia previa de caries, entre otros. Estudios epidemiológicos nacionales realizados en el año 2007 en niños de 6 años demuestran que la prevalencia de caries sigue siendo alta (70,36%) en comparación a la estadística obtenida en el año 1992 (70,8%)1. Otros estudios han demostrado que la prevalencia de este tipo de lesiones cariosas en pacientes pediátricos menores a 48 meses es de 35%, porcentaje que aumenta con la edad2. La Academia Americana de Odontología Pediátrica (AAPD) define caries temprana de la infancia a la presencia, en dientes temporarios, de 1 o más superficies cariadas (cavitadas o no), perdidas (por caries) u obturadas en niños menores de 71 meses de edad (5 años y 11 meses), por lo que en menores de 3 años, cualquier signo de caries en una superficie lisa, es indicativo de presencia de caries temprana de la infancia severa (CTIs)3. Sin embargo en la mayoría de los casos es indispensable restaurar estas lesiones debido al gran compromiso de estructura dentaria que ellas presentan. Es este el motivo por el cual se ha intentado buscar o generar a través de los avances científicos materiales compatibles con las características de los tejidos dentales. Dentro de los materiales restauradores estéticos para este tipo de lesiones encontramos vidrios ionómeros convencionales, vidrios ionómeros modificados con resinas, vidrios ionómeros de alta densidad y resinas compuestas. 5 Los vidrios ionómeros han ido evolucionando en el tiempo, mejorando sus propiedades. Actualmente los vidrios ionómeros de alta densidad (Ketac Molar EM, 3M-ESPE; Fuji IX GP, GC; Ionofil Molar ART, VOCO) permiten tiempos de trabajo más convenientes, mejor resistencia compresiva, resistencia flexural y al desgaste, junto con una solubilidad mínima, manteniendo su activación química4. Por otro lado las resinas compuestas tienen un lugar fundamental en la odontología restauradora debido a sus múltiples propiedades y variadas indicaciones. La disponibilidad de sistemas adhesivos eficaces ofrecen alternativas conservadoras a los tratamientos, proporcionando mejor durabilidad, resistencia y estética satisfactoria5. El siguiente estudio tiene como objetivo comparar la resistencia a la tracción y compresión in vitro de la resina compuesta v/s vidrio ionómero de alta densidad como material de restauración en preparaciones cavitarias estandarizadas en dientes temporales extraídos

Export of Commercial Hass Avocados From Argentina Poses Negligible Risk of Ceratitis capitata (Diptera: Tephritidae) Infestation

Argentina has to meet quarantine restrictions because of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), to export 'Hass' avocados, Persea americana Miller, to certain countries. Hass avocado at the hard, mature green stage is potentially a conditional nonhost for C. capitata and could open export markets without the need for a quarantine treatment. Trapping data from 1998 to 2006 showed that C. capitata was present in avocado orchards, particularly early in the harvest season. The host status of hard, mature green Hass avocado to C. capitata was evaluated using laboratory and field cage tests under no-choice conditions and by assessing natural levels of infestation in commercially harvested fruit from the main avocado production area. In total, 2,250 hard, mature green avocado fruit were exposed to 11,250 gravid females for 24 or 48 h after harvest in laboratory or field cages, and no infestations were found. During 11 seasons, 5,949 fruit in total were sampled from the trees and 992 fruit were collected from the ground, and in none of them were any live or dead fruit fly larvae found. Inspection of >198,000 commercial fruit at the packinghouse from 1998 to 2011 showed no symptoms of fruit fly infestation. These data exceed the published standards for determination of nonhost status, as well as the Probit 9 standard for development of quarantine treatments. Hass avocado harvested at the hard, mature green stage was not infested by C. capitata and seems to pose a negligible quarantine risk. As a consequence, no postharvest treatment or other quarantine actions should be required by importing countries.Fil: Elvira Villagrán, M.. Gobierno de Tucumán. Ministerio de Desarrollo Productivo.

Antler velvet is thicker in adult than in yearling pampas deer (Ozotoceros bezoarticus): a histological study

Background: Antlers are lined by soft velvet tissue during antler growth. Later, the velvet is shed before rut onset. There are no detailed histological descriptions of the growing velvet, nor whether the velvet changes according to stag age. Our aims were to: 1) describe the basic histology of pampas deer antler velvet from adult and yearling males; and 2) determine the influence of age and time of antler growth on velvet’s tissues morphometry. Materials and methods: Samples were collected from 10 stags allocated in two groups, either adult (3–5 years old, n = 5) or yearling males (2 years old, n = 5). The day of antler cast was recorded for each animal. In spring, the stags were anaesthetised and velvet samples were collected from the third tine’s distal end. Samples were described qualitatively and a restricted morphometrical analysis of the antler velvet was performed. Results: The number of keratinocyte layers and the thicknesses of: total epidermis, corneum, intermediate and basale epidermal strata, total dermis, superficial and deep dermis were determined. Age and days after antler casting positively influenced in conjunction epidermal thickness (p = 0.037), and tended to influence both stratum intermedium (p = 0.076) and stratum corneum (p = 0.1) thicknesses. Age influenced stratum corneum thickness (p = 0.04). The pampas deer antler velvet lacked both sweat glands and arrector pili muscles. Conclusions: The deep dermis was densely irrigated but displayed abundant and well developed collagen bundles. Both total epidermal and stratum corneum thicknesses related positively to the age of the animals but were not to the time since antler cast.

Microsatellite analysis of populations of the endangered tree Gomortega keule suggests pre-Columbian differentiation

Temperate forests have been affected extensively by human activities, resulting in land cover changes and population fragmentation. However, these anthropogenic effects can be superimposed onto the natural history of species, making it difficult to determine which effect is more important for a particular species. Gomortega keule is an endangered tree that is found in one of the world’s biodiversity hotspots in central–south Chile. Human activities have significantly impacted on the original habitat in this region in recent years and are commonly considered to be the main cause of the scarcity of this species. However, aspects of the natural history of this evergreen tree may also help to explain its present-day genetic structure. In this study, we undertook microsatellite genotyping of the two southernmost populations of G. keule, which are 7.5 km apart and well isolated from other populations. We found that there was genetic differentiation between these populations, suggesting that they exhibited at least some differentiation before becoming isolated, most likely before human activities first impacted the region some two centuries ago. Molecular estimates of their divergence time supported a more ancient differentiation of the populations than would be explained by human activities alone. It is possible that their isolation may have followed the extinction of megafaunal seed dispersers around 12,000 years before present in this region, as indicated by fruit characteristics, the absence of recruitment by seedlings and the existence of clonal trees

Photocatalytic reactions of a nickel(II) annulene complex incorporated in polymeric structures

The photochemical reactions of the Ni(II) annulene complex, [NiII([5,7,12,14]-tetra methyl dibenzo[2,3- b:2,3-b,i][1,4,8,11]tetraaza[14]annulenate)], grafted into a poly(isobutylene-alt-maleate) backbone were investigated in aqueous media. The grafted Ni(II) complex becomes soluble in aqueous and organic solvents where the strands form aggregates with medium-dependent shapes. Irradiation of the polymer at 532 or 351 nm produce charge-separated macrocyclic pendants, CS, with a lifetime s 30 ns. CS reacts with electron donors and acceptors before it decays with a lifetime s 1 ms. In parallel to the decay of CS, an excited state-excited state annihilation process gives rise to luminescence whose spectrum spans wavelengths shorter than the wavelength of the irradiation, lex > 500 nm. Theoretical calculations were carried out with the aim of understanding the morphology and structures of strand aggregates, to confirm the nature of reaction products and to account for the spectroscopic and photochemical properties of the Ni(II) pendants. The endothermic reduction of CO2 to CO by S(IV) species was used as a test of the Ni(II) complex´s ability to photocatalyze the reaction. In the photoprocess, the Ni(II) complex fulfills the double role of antenna and catalyst.Fil: Estiu, G.. University Of Notre Dame-indiana; Estados UnidosFil: Ferraudi, G..

Solution and Asymptotic Behavior for a Nonlocal Coupled System of Reaction-Diffusion

This paper concerns with existence, uniqueness and asymptotic behavior of the solutions for a nonlocal coupled system of reaction-diffusion. We prove the existence and uniqueness of weak solutions by the Faedo-Galerkin method and exponential decay of solutions by the classic energy method. We improve the results obtained by Chipot-Lovato and Menezes for coupled systems. A numerical scheme is presented
