Short Course for Focused Assessment with Sonography for Human Immunodeficiency Virus/Tuberculosis: Preliminary Results in a Rural Setting in South Africa with High Prevalence of Human Immunodeficiency Virus and Tuberculosis

In Africa, human immunodeficiency virus (HIV)–associated extrapulmonary tuberculosis (TB) is common and poses diagnostic difficulties. Ultrasound is useful to find suggestive signs such as effusions or abdominal lymphadenopathy. Because trained radiologists are scarce in resource-poor settings, even this simple and relatively inexpensive diagnostic tool is frequently unavailable to patients in district hospitals in sub-Saharan Africa. We developed a focused protocol for assessment with sonography for HIV/TB and trained physicians in a rural district hospital in South Africa. In this pilot study, high levels of confidence in identifying specific signs were rapidly achieved and ultrasound was introduced into routine clinical practice

The mitochondrial genome of the springtail Bourletiella arvalis (Symphypleona, Collembola)

The complete mitochondrial genome of the springtail Bourletiella arvalis (Fitch, 1863) is herein described and applied to a Bayesian phylogenetic analysis, inclusive of all the Collembola mitochon- drial DNAs sequenced so far. The gene content and order, as well as the nucleotide composition, con- form with the well-known features of hexapods’ mitochondrial genomes. The phylogenetic analysis supports the monophyly of Collembola, Poduromorpha, Entomobryomorpha and Symphypleona. However, no mtDNA from Neelipleona is available to date, therefore limiting the application of mito- chondrial genomes to further investigate springtail systematics

The mitogenome of the jumping bristletail Trigoniophthalmus alternatus (Insecta, Microcoryphia) and the phylogeny of insect early-divergent lineages

The complete mitochondrial genome of the machilid Trigoniophthalmus alternatus (Silvestri 1904) is herein described and applied to phylogenetic analyses, inclusive of the most early-divergent lineages of hexapods. Both gene content and order generally conform with the organization of the arthropods’ mitochondrial genome. One gene translocation involving trnA is the autapomorphic character observed in this species. Another peculiar molecular feature is the long size of the A + T-rich region, due to the occurrence of repeat units. The phylogenetic analyses support the typical placement, along the hexapods’ tree, of Ectognatha, Monocondylia and Dicondylia, with Diplura as the adelphotaxon of all true insects

Variación espacial de las temperaturas medias mensuales (máximas y mínimas) en España (1981-2010)

Ponencia presentada en: IX Congreso de la Asociación Española de Climatología celebrado en Almería entre el 28 y el 30 de octubre de 2014.[ES]En este trabajo se analiza la variabilidad espacial de los promedios mensuales de las temperaturas diurnas (máximas, Tmax) y nocturnas (mínimas, Tmin) en la España peninsular (1981-2010), por medio de la función denominada Correlation Decay Distance (CDD), que estima la distancia a la que se mantiene un valor de varianza común entre observatorios vecinos.[EN]The spatial variability of the average monthly diurnal (maximum, Tmax) and nocturnal (minimum, Tmin) temperatures is analyzed in the Spanish conterminous land (1981- 2010). To this end, the Correlation Decay Distance function (CDD) is used. The CDD estimates the distance at which a common variance value, determined by the neighboring stations, is maintained.Apoyo financiero del Gobierno de España-FSE, Proyecto CGL2011-27574-C02-01, y Gobierno Regional de Aragón DGA-FSE, y el grupo de investigación consolidado "Clima, Agua y Cambio Global y Sistemas Naturales" (BOA 69, 11-06-2007)

Variación espacial de las tendencias de los promedios estacionales de las máximas y de las mínimas en España (1951-2010)

Ponencia presentada en: IX Congreso de la Asociación Española de Climatología celebrado en Almería entre el 28 y el 30 de octubre de 2014.[ES]El análisis espacial de las tendencias de las temperaturas estacionales de la base de datos MOTEDAS, (MOnthly TEmperature DAtaset of Spain) muestra un aumento significativo y generalizado de los promedios de las máximas en invierno y verano en más del 80% del territorio y en menor extensión en primavera (57%), mientras se ha detectado tendencias positivas y significativas en los promedios de las mínimas en más del 75% del territorio en verano y primavera, y en menor extensión en otoño (47% del territorio) y en invierno (30,1% del territorio). La evolución de las tasas en intervalos secuenciados de treinta años (inicio 1951-1980) indica desde el máximo periodo de calentamiento (1971-2000) que solamente el verano mantiene una evolución positiva. Se discute la posible naturaleza de la variación espacial observada en las tendencias y su posible relación con los cambios de uso del suelo.[EN]Seasonal trend analyses of temperature dataset MOTEDAS (MOnthly TEmperature DAtaset of Spain) show a significant and positive evolution of diurnal winter and summer (>80% of land) and to a lesser extend during spring (57% of land), while significant and positive trend were detected over 75% of land in summer and spring minimum, only in 47% of land in autumn and 30.1% of land in winter. Temporal analyses of rates shows only positive rates persist in summer. We discuss different explanations and suggest the eventual effects of land use changed occurred in Spain as a factor to be considered.AEMet (disponibilidad de datos), financiación: Gobierno de España-FSE, Proyecto CGL2011-27574-C02-01, Gobierno Regional de Aragón DGA-FSE, Grupo de Investigación Consolidado "Clima, Agua, Cambio Global y Sistemas Naturales" (BOA 69, 11-06-2007).

Castro Lusitano Virtual: Software Livre e Património Virtual

O presente texto apresenta os objetivos e atual estado de desenvolvimento do projeto Castro Lusitano Virtual, um ambiente tridimensional interativo representativo de um povoado da Idade do Ferro da região Centro de Portugal, juntamente com a descrição de alguns conceitos que constituem o respetivo enquadramento e fundamentos do projeto. A Arqueologia e o Património Virtual são convocados nesse sentido, assim como a ecologia de conceitos e práticas em torno do Software Livre, incluindo cultura livre. O Castro Lusitano Virtual pode ser considerado como um recurso educacional aberto (Open Educational Resource), discutindo-se ideias sobre a sua utilização, nomeadamente distinguindo o aluno como explorador e como criador de ambiente tridimensionais. A utilização do projeto é focada, neste artigo, no contexto escolar, nomeadamente no ensino da História

Overlooked species diversity and distribution in the Antarctic mite genus Stereotydeus

In the harsh Antarctic terrestrial ecosystems, invertebrates are currently confined to sparse and restricted ice free areas, where they have survived on multi-million-year timescales in refugia. The limited dispersal abilities of these invertebrate species, their specific habitat requirements, and the presence of geographical barriers can drastically reduce gene flow between populations, resulting in high genetic differentiation. On continental Antarctica, mites are one of the most diverse invertebrate groups. Recently, two new species of the free living prostigmatid mite genus Stereotydeus Berlese, 1901 were discovered, bringing the number of Antarctic and sub-Antarctic species of this genus up to 15, of which 7 occur along the coast of Victoria Land and in the Transantarctic Mountains. To examine the biodiversity of Stereotydeus spp., the present study combines phylogenetic, morphological and population genetic data of specimens collected from nine localities in Victoria Land. Genetically distinct intraspecific groups are spatially isolated in northern Victoria Land, while, for other species, the genetic haplogroups more often occur sympatrically in southern Victoria Land. We provide a new distribution map for the Stereotydeus species of Victoria Land, which will assist future decisions in matters of the protection and conservation of the unique Antarctic terrestrial fauna
