Malófagos encontrados sobre pollos de Garza imperial Ardea purpurea y Garceta común Egretta garzetta en la Albufera de Mallorca

Mallophaga found on chicks of purple heron Ardea purpurea and little egret Egretta garzetta at S’Albufera de Mallorca. We describe the species of chewing lice found on ten purple heron Ardea purpurea) chicks and seven little egret Egretta garzetta chicks inspected in S’Albufera de Mallorca Natural Park (Balearic Islands, Spain) in 2008. Ardeicola leucoproctus was found on the head of one of the herons, whereas Ciconiphilus decimphastiatus was detected on the wings of two other herons and in five egrets. This is the first observation of A. leucoproctus in Europe, though it is known to parasitize the purple heron in other locations. Ciconiphilus decimphastiatus has been described parasitizing Ardeid species in the Iberian peninsula but not in the Balearic Islands. The transmission of these parasites probably follows a vertical route. The low prevalence observed, together with the detection of species typical of Ardeidae, may indicate that the birds inspected were in a condition of good health

The Correlation between Bone Density and Mechanical Variables in Bone Remodelling Models: Insights from a Case Study Corresponding to the Femur of a Healthy Adult

Bone remodelling models (BRM) are often used to estimate the density distribution in bones from the loads they are subjected to. BRM define a relationship between a certain variable measuring the mechanical stimulus at each bone site and either the local density or the local variation of density. This agrees with the Mechanostat Theory, which establishes that overloaded bones increase their density, while disused bones tend to decrease their density. Many variables have been proposed as mechanical stimuli, with stress or strain energy density (SED) being some of the most common. Yet, no compelling reason has been given to justify the choice of any of these variables. This work proposes a set of variables derived from the local stress and strain tensors as candidates for mechanical stimuli; then, this work correlates them to the density in the femur of one individual. The stress and strain tensors were obtained from a FE model and the density was obtained from a CT-scan, both belonging to the same individual. The variables that best correlate with density are the stresses. Strains are quite uniform across the femur and very poorly correlated with density, as is the SED, which is, therefore, not a good variable to measure the mechanical stimulus

Materialities, Space, Mind: Archaeology of Visual Cognition

A perceptual study of different styles of prehistoric Galician ceramics (from 6000 to 2000 BP) conducted by eye-tracking, underpins the material engagement of mind by showing that the visual world fosters the entanglement between doing, seeing, and designing through history. This text examines how materializations of human practices relate to cognition and to socio-cultural contexts. By combining evidence on the relationship between material culture and perceptual reactions, our text aims to understand the entanglement between the mind, objects and the world. We apply measurable and numeric techniques, providing an archaeometric approach to cognitive topics by combining neurosciences with interpretive and reflective research. This research provides new insights into the material culture, contributes to the understanding of the relationship between mind and the material world, and accounts for the transitive engagement between the way of thinking, seeing and making things. Thus, the text contributes to an understanding of the material forces driving perception and thought

Religious tourism in Los Altos de Jalisco and Andalucía: comparison of the supply and demand between two Marian sanctuaries

En los últimos años se asiste a un redescubrimiento turístico de lugares y eventos de carácter religioso y espiritual, generando una nueva modalidad de turismo, el religioso, siendo esta una opción estratégica de desarrollo económico sostenible de las zonas donde se ubican los centros de peregrinación. Los Altos de Jalisco en México, es una Región ubicada al centro occidente del país que cuenta con un importante flujo de turistas con motivo del peregrinaje religioso que miles de personas realizan cada año para visitar el segundo Santuario Mariano más visitado de México, el de la Virgen de San Juan de los Lagos, así como varios otros dedicados a los mártires de la Guerra Cristera, canonizados por la Iglesia Católica en el año 2000. En este estudio se pretende hacer una comparativa a partir de la experiencia española en la creación de productos turísticos y determinar cuáles son los elementos que existen en Los Altos de Jalisco, para la creación de una Ruta Religiosa de características similares a las que actualmente se ofertan en la Península Ibérica, especialmente en Andalucía.In recent years there has been a touristic rediscovery of religious and spiritual places and events, creating a new kind of tourism, the religious, this being a strategic option for sustainable economic growth on the areas where pilgrimage centers are located. Los Altos de Jalisco in Mexico, it a Region located in the west central part of the country and has an important influx of tourists on religious pilgrimages. Every year thousands of people come to the second most popular Marian Sanctuary in Mexico, the Sanctuary of The Virgin of San Juan de los Lagos, and to several other sanctuaries dedicated to the martyrs of the Cristera War, canonized by the Catholic Church in the year 2000. This research will make a comparison between the Spanish way of creating tourist interests and determine which elements exists in Los Altos de Jalisco for creating a Religious Route with similar characteristics to those that are found today on the Iberian Peninsula, especially in Andalucía

Aerosol analysis by micro laser-induced breakdown spectroscopy: A new protocol for particulate matter characterization in filters

Atmospheric aerosols (particulate matter – PM) affect the air quality and climate, even in remote areas, such as the Antarctic Region. Current techniques for continuous PM monitoring are usually complex, costly, time consuming and do not provide real-time measurements. In this work, based on micro laser-induced breakdown spectroscopy (LIBS), an innovative method with an optical design and multi-elemental scanning imaging, is presented to characterize PM collected in filters from Antarctica. After following a simple protocol and under atmospheric pressure, the new approach allows to obtain a global visualization of the elemental PM composition of the filters with a minimum sample destruction and preparation. For the first time, we were able to map the localization of pollutants in filters at high spatial resolution and speed. This recent method offers a new insight on the characterization of PM, particularly in isolated areas, where no complex equipment and real time measurements are demanded

Extending Graph (Discrete) Derivative Descriptors to N-Tuple Atom-Relations

In the present manuscript, an extension of the previously defined Graph Derivative Indices (GDIs) is discussed. To achieve this objective, the concept of a hypermatrix, conceived from the calculation of the frequencies of triple and quadruple atom relations in a set of connected sub-graphs, is introduced. This set of subgraphs is generated following a predefined criterion, known as the event (S), being in this particular case the connectivity among atoms. The triple and quadruple relations frequency matrices serve as a basis for the computation of triple and quadruple discrete derivative indices, respectively. The GDIs are implemented in a computational program denominated DIVATI (acronym for DIscrete DeriVAtive Type Indices), a module of TOMOCOMD-CARDD program. Shannon‟s entropy-based variability analysis demonstrates that the GDIs show major variability than others indices used in QSAR/QSPR researches. In addition, it can be appreciated when the indices are extended over n-elements from the graph, its quality increases, principally when they are used in a combined way. QSPR modeling of the physicochemical properties Log P and Log K of the 2-furylethylenes derivatives reveals that the GDIs obtained using the tripleand quadruple matrix approaches yield superior performance to the duplex matrix approach. Moreover, the statistical parameters for models obtained with the GDI method are superior to those reported in the literature by using other methods. It can therefore be suggested that the GDI method, seem to be a promissory tool to reckon on in QSAR/QSPR studies, virtual screening of compound datasets and similarity/dissimilarity evaluations

Reduced membrane-bound alkaline phosphatase does not affect binding of Vip3Aa in a Heliothis virescens resistant colony

The Vip3Aa insecticidal protein from Bacillus thuringiensis (Bt) is produced by specific transgenic corn and cotton varieties for efficient control of target lepidopteran pests. The main threat to this technology is the evolution of resistance in targeted insect pests and understanding the mechanistic basis of resistance is crucial to deploy the most appropriate strategies for resistance management. In this work, we tested whether alteration of membrane receptors in the insect midgut might explain the >2000-fold Vip3Aa resistance phenotype in a laboratory-selected colony of Heliothis virescens (Vip-Sel). Binding of 125I-labeled Vip3Aa to brush border membrane vesicles (BBMV) from 3rd instar larvae from Vip-Sel was not significantly different from binding in the reference susceptible colony. Interestingly, BBMV from Vip-Sel larvae showed dramatically reduced levels of membrane-bound alkaline phosphatase (mALP) activity, which was further confirmed by a strong downregulation of the membrane-bound alkaline phosphatase 1 (HvmALP1) gene. However, the involvement of HvmALP1 as a receptor for the Vip3Aa protein was not supported by results from ligand blotting and viability assays with insect cells expressing HvmALP1
