Diet and lifestyle in Bronze Age Northwest Spain: the collective burial of Cova do Santo

A multidisciplinary investigation of the collective burial of Cova do Santo is presented as a novel approach to understand daily life during the Bronze Age in Northwest Iberia. The research is focused on three main aspects: i) taphonomy and patterns of disposal, ii) paleopathology and -demography as indicators of health status and lifestyle, and iii) stable isotope analysis to reconstruct paleodiet and to investigate the timing of the introduction of millet to the Iberian Peninsula. Osteological analyses were performed on 64 bones (61 human and 3 animal); additionally, bone collagen was extracted from 15 samples (13 human and 2 animal) and analyzed for its carbon and nitrogen stable isotopes composition. The radiocarbon age of the human remains is consistent with the Middle Bronze Age (c. 1890 to 1600 cal BC). The recovered remains belonged to a minimum number of 14 individuals with an estimated age at death of forty years or younger. This relatively young age is in contrast to a high prevalence of degenerative joint disease in the group. The isotopic results suggest a very homogeneous diet, which was almost exclusively based on C3 plants and terrestrial animal products. Overall, the data suggest that the studied population belonged to a period prior to the introduction of spring or summer-grown crops such as millets. The collective burial from the cave of Cova de Santo, Galicia, currently represents the largest assemblage of prehistoric human remains from Northwest Spain and the relatively good preservation of the bones offers a unique opportunity to investigate daily life in Northern Iberia during the Bronze Age.

First record of Stygnidae for the state of Espirito Santo and description of a new Protimesius (Arachnida : Opiliones : Laniatores)

Protimesius osvaldoi sp. nov. is described from the Reserva Biologica de Sooretama, state of Espirito Santo, Southeastern Brazil, being the First record of Stygnidae from this State and the southernmost record of the family in the Brazilian Atlantic Forest (hitherto, the family was recorded down to Bahia only), extending in 210 km south of the previously known distribution. This is a large species, with armature of leg IV very reduced and penial morphology differing from the closest counterparts mainly in the ventral plate, which recedes deeply at the lateral borders and has the distal margin curved ventrally and by the presence of two small intermediate setae. Protimesius Roewer, 1913 consisted hitherto of 17 species, recorded from northern/northeastern Brazil and Amazonia of adjacent Countries. A key is given for the 17 species of Protimesius for which males are known.

A new species of Lauromacromia (Odonata: Corduliidae) from Southeastern Brazil, with a cladistic analysis of the genus and comments on Neotropical dragonfly biogeography

Lauromacromia melanica sp. nov. from Conceicao da Barra municipality, Espirito Santo State, Brazil, is described and illustrated based on two males (both in MNRJ n degrees 135). The new species is similar to L. picinguaba differing from it mainly by the absence of pale spots on S3-6 and by the ellipsoid shape of metepisternal pale stripe. A key for males of all species of the genus is provided. A cladistic analysis encompassing 43 external morphological male characters carried out in two distinct procedures, the first with all characters unordered and the second with two or three state characters ordered. The unordered analysis generated only one most-parsimonious tree (66 steps of length, CI = 0.69, RI = 0.62). The hypothesis of monophyly of Lauromacromia is supported and includes three groups, one formed by the Atlantic Forest species (L. melanica sp. nov. + L. picinguaba), and another by the Cerrado species (L. flaviae + (L. bedei + L. luismoojeni)), and L. dubitalis, positioned in polytomy with these two groups. The ordered analysis also generated only one most-parsimonious tree (68 steps of length, CI = 0.70, RI = 0.67), which maintained the monophyly of Lauromacromia but L. dubitalis positioned basally as sister-group to the Atlantic Forest + Cerrado species groups. The geographic distribution of Lauromacromia is updated with a new record of L. luismoojeni based on one adult male (Brazil: Mato Grosso do Sul State) and probable first Brazilian records for L. dubitalis (Amazonas and Para States) based on two larvae. A vicariance hypothesis is proposed to explain spatial evolution of Lauromacromia, and based on current biogeographical classifications we consider Gomphomacromia and Rialla apart from Neotropical biota. Some aspects of biology and ecology of Lauromacromia are also discussed.

The magnetized steel and scintillator calorimeters of the MINOS experiment

The Main Injector Neutrino Oscillation Search (MINOS) experiment uses an accelerator-produced neutrino beam to perform precision measurements of the neutrino oscillation parameters in the ""atmospheric neutrino"" sector associated with muon neutrino disappearance. This long-baseline experiment measures neutrino interactions in Fermilab`s NuMI neutrino beam with a near detector at Fermilab and again 735 km downstream with a far detector in the Soudan Underground Laboratory in northern Minnesota. The two detectors are magnetized steel-scintillator tracking calorimeters. They are designed to be as similar as possible in order to ensure that differences in detector response have minimal impact on the comparisons of event rates, energy spectra and topologies that are essential to MINOS measurements of oscillation parameters. The design, construction, calibration and performance of the far and near detectors are described in this paper. (C) 2008 Elsevier B.V. All rights reserved.

Upper limit on the cosmic-ray photon flux above 10(19) eV using the surface detector of the Pierre Auger Observatory

A method is developed to search for air showers initiated by photons using data recorded by the surface detector of the Auger Observatory. The approach is based on observables sensitive to the longitudinal shower development, the signal risetime and the curvature of the shower front. Applying this method to the data, tipper limits on the flux of photons of 3.8 x 10(-3), 2.5 x 10(-3), and 2.2 x 10(-3) km(-2) sr(-1) yr(-1) above 10(19) eV, 2 x 10(19) eV, and 4 x 10(19) eV are derived, with corresponding limits on the fraction of photons being 2.0%, 5.1%, and 31% (all limits at 95% c.l.). These photon limits disfavor certain exotic models of sources of cosmic rays. The results also show that the approach adopted by the Auger Observatory to calibrate the shower energy is not strongly biased by a contamination from photons. (C) 2008 Elsevier B.V.

Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei

Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival directions of the cosmic rays with the highest-energies, which are correlated with the positions of relatively nearby active galactic nuclei (AGN) [Pierre Auger Collaboration, Science 318 (2007) 938]. The correlation has maximum significance for cosmic rays with energy greater than similar to 6 x 10(19) eV and AGN at a distance less than similar to 75 Mpc. We have confirmed the anisotropy at a confidence level of more than 99% through a test with parameters specified a priori, using an independent data set. The observed correlation is compatible with the hypothesis that cosmic rays with the highest-energies originate from extra-galactic sources close enough so that their flux is not significantly attenuated by interaction with the cosmic background radiation (the Greisen-Zatsepin-Kuz`min effect). The angular scale of the correlation observed is a few degrees, which suggests a predominantly light composition unless the magnetic fields are very weak outside the thin disk of our galaxy. Our present data do not identify AGN as the sources of cosmic rays unambiguously, and other candidate sources which are distributed as nearby AGN are not ruled out. We discuss the prospect of unequivocal identification of individual sources of the highest-energy cosmic rays within a few years of continued operation of the Pierre Auger Observatory.

Advanced functionality for radio analysis in the Offline software framework of the Pierre Auger Observatory

The advent of the Auger Engineering Radio Array (AERA) necessitates the development of a powerful framework for the analysis of radio measurements of cosmic ray air showers. As AERA performs ""radio-hybrid"" measurements of air shower radio emission in coincidence with the surface particle detectors and fluorescence telescopes of the Pierre Auger Observatory, the radio analysis functionality had to be incorporated in the existing hybrid analysis solutions for fluorescence and surface detector data. This goal has been achieved in a natural way by extending the existing Auger Offline software framework with radio functionality. In this article, we lay out the design, highlights and features of the radio extension implemented in the Auger Offline framework. Its functionality has achieved a high degree of sophistication and offers advanced features such as vectorial reconstruction of the electric field, advanced signal processing algorithms, a transparent and efficient handling of FFTs, a very detailed simulation of detector effects, and the read-in of multiple data formats including data from various radio simulation codes. The source code of this radio functionality can be made available to interested parties on request. (C) 2011 Elsevier B.V. All rights reserved.

Ixolaris, a tissue factor inhibitor, blocks primary tumor growth and angiogenesis in a glioblastoma model

Background: The expression levels of the clotting initiator protein Tissue Factor (TF) correlate with vessel density and the histological malignancy grade of glioma patients. Increased procoagulant tonus in high grade tumors (glioblastomas) also indicates a potential role for TF in progression of this disease, and suggests that anticoagulants could be used as adjuvants for its treatment. Objectives: We hypothesized that blocking of TF activity with the tick anticoagulant Ixolaris might interfere with glioblastoma progression. Methods and results: TF was identified in U87-MG cells by flow-cytometric and functional assays (extrinsic tenase). In addition, flow-cytometric analysis demonstrated the exposure of phosphatidylserine in the surface of U87-MG cells, which supported the assembly of intrinsic tenase (FIXa/FVIIIa/FX) and prothrombinase (FVa/FXa/prothrombin) complexes, accounting for the production of FXa and thrombin, respectively. Ixolaris effectively blocked the in vitro TF-dependent procoagulant activity of the U87-MG human glioblastoma cell line and attenuated multimolecular coagulation complexes assembly. Notably, Ixolaris inhibited the in vivo tumorigenic potential of U87-MG cells in nude mice, without observable bleeding. This inhibitory effect of Ixolaris on tumor growth was associated with downregulation of VEGF and reduced tumor vascularization. Conclusion: Our results suggest that Ixolaris might be a promising agent for anti-tumor therapy in humans.

Un estudio de La Sombra del Viento de Carlos RuizZafón desde una perspectiva de género

Esta tesina tiene el propósito de analizar las características de algunos de lospersonajes principales de La Sombra del Viento de Carlos Ruiz Zafón desde un punto de vistade género. El estudio se basa en diferentes teorías de género que pretenden funcionar comoherramientas para poder destacar las diferencias entre las descripciones femeninas y lasmasculinas que aparecen en la obra. Primero, definimos y concretamos el término género conla ayuda de las teorías de Yvonne Hirdman. En segundo lugar, presentamos la teoría deldualismo, de acuerdo con la cual Lena Gemzöe hace una división entre las cualidadesmasculinas y femeninas. El objetivo de nuestro estudio ha sido hacer un análisis de lascaracterísticas de algunos de los personajes principales de para demostrar si existenconstrucciones de identidad de género desde una perspectiva dualista. Como resultado denuestro estudio podemos afirmar que Zafón refuerza la división entre las cualidadesmasculinas y femeninas. Los personajes masculinos son descritos como fuertes, valientes,lógicos, intelectuales e independientes. Paralelamente, las mujeres son descritas como débiles,cobardes, intuitivas y dependientes. Además, consideramos que Zafón da a todos lospersonajes masculinos mayor espacio, estatus y protagonismo en el desarrollo de la historia.En todo momento, queda claro que Zafón crea de forma inconsciente el orden de género yrefuerza así las diferencias sexuales.

Contribuição ao estudo petrográfico e geoquímico dos carvões da jazida de Chico Lomã Santo Antônio da Patrulha

São apresentados os resultados dos estudos petrográfico e geoquímico dos carvões da jazida de Chico Lomã, localizada no município de Santo Antônio da Patrulha, no nordeste do Rio Grande da Sul, situada entre as jazidas de Morungava (limite oeste) e Santa Terezinha (limite leste). Na sondagem estudada - 02-TG-88-RS - foram identificadas 7 camadas e 5 leitos de carvão. Entre estes, apenas as camadas E e F apresentam suficiente extensão lateral para serem consideradas economicamente exploráveis. Os carvões são ricos em matéria mineral, constituída, principalmente, de argila. O grupo maceral mais freqüente é o da vitrinita. No que diz respeito aos microlitotipos, ocorre, em geral, o predomínio de carbominerita. Foram identificadas 3 associações de microlitotipos, determinando a existência das seguintes faciologias: ambiente telmático (predomínio de vitrita-clarita), limo-telmático (predomínio de carbargilita-vitrita) e límnico (predomínio de carbargilita-durita-trimacerita). Os carvões apresentam rank que varia de betuminoso alto volátil C/sub-betuminoso A a betuminoso alto volátil A (ASTM). A utilização tecnológica dos carvões das camadas E e F, na siderurgia, pode ser sugerida, mesmo considerando-se seu elevado teor em cinza, desde que sejam submetidos a processos de beneficiamento. Em relação aos argilo-minerais, constatou-se a presença de caolinita, aparentemente relacionada ao conteúdo da matéria orgânica, e do interestratificado ilita-montmorilonita, provavelmente de origem detrítica. Foram identificados 3 grupos de elementos traços : associados à fração orgânica (Co, Ge, Ni, V e Zr), elementos intermediários (Cr, Cu e Sr) e associados à fração inorgânica (B, Ba e Ga). Observou-se, também, que os elementos do primeiro grupo, de maneira geral, se enriquecem nos litotipos com maior conteúdo de vitrênio, ao contrário dos elementos do último grupo que tendem a se enriquecer no carvão fosco e nos folhelhos. Os estudos realizados indicam um paleoambiente de água doce, no qual, provavelmente, tenham ocorrido pequenas ingressões marinhas entre as fases de formação de turfa.
