Apuntes sobre la percepción subconsciente en el cine: el ejemplo de Alien, el octavo pasajero (1979) y su propuesta orgánica de atracción/repulsión

En una revisión profunda en la que se aportan datos hasta ahora inéditos, el presente artículo analiza nuevas claves de por qué la película Alien, el octavo pasajero (Ridley Scott, 1979), ha causado una atracción sobredimensionada del espectador en su estreno y reposición a lo largo de más de tres décadas. Se propone la tesis de que el film emplea un conjunto de símbolos audiovisuales ocultos o semi-ocultos que provocan sensaciones de placer/displacer (eros y tanatos) y son las causantes directas de sus nutridas afinidades. Se explicita además cómo en el diseño/ presentación de un universo alienígena aparentemente nuevo (respecto al cine de ciencia ficción precedente) el espectador asume una mímesis identificativa y orgánica que se introduce en las profundidades del inconsciente, despertando un interés sorprendente entre audiencias de diferentes generaciones y edades. Se analiza el fenómeno subliminal o subconsciente en el cine, desde el punto de vista de la percepción, a partir de los experimentos publicitarios de los años 50 en una sala de exhibición de los Estados Unidos. También se estudia por primera vez el curioso paralelismo del argumento de la película con el impacto mediático previo y simultáneo del primer bebé probeta nacido el 25 de julio de 1978, en pleno inicio del rodaje de este film en los estudios londinenses Shepperton.

La infraestructura hidráulica y la gestión del agua en los regadíos tradicionales en la Vega Baja del Segura (Alicante)

La agricultura tradicional de la comarca de la Vega Baja del Segura se asienta sobre la llanura aluvial creada por el río a lo largo de la historia. Cuenta con una superficie regable de unos 190 km2 que se nutre con recursos propios de la cuenca del río Segura. Las aguas son desviadas del río mediante azudes y distribuidas, por simple gravedad, a través de un complejo sistema de acueductos, acequias y azarbes, que configuran sendas redes de aguas vivas y de aguas muertas, permitiendo la reutilización de las aguas. El presente trabajo tiene por finalidad el estudio de las infraestructuras hidráulicas y su papel en la gestión de los recursos hídricos para el riego en la comarca de la Vega Baja del Segura. A tal fin, se ha consultado la bibliografía y recabado información en diferentes juzgados de aguas, sindicatos de riego y comunidades de regantes, complementándose todo ello con visitas de campo para la toma de datos e imágenes. Los resultados obtenidos muestran una gestión eficiente de los escasos recursos hídricos disponibles y un aprovechamiento óptimo de los mismos, en cuanto que, al final, el sistema cede sus aguas sobrantes a otros regadíos para ser reutilizadas.

El sur también existe: las relaciones migratorias entre las islas Baleares y la Argelia francesa (1830-1962)

La Argelia francesa (1830-1962) constituyó un poderoso polo de atracción para los habitantes de las islas Baleares y del sudeste peninsular. En este artículo se analizan las relaciones migratorias y comerciales entre el archipiélago balear y su por entonces próspero vecino del sur. Además, también se estudian los diferentes exilios que vincularon las dos riberas del Mediterráneo. Para realizar este artículo se han combinado tanto fuentes primarias como la bibliografía existente.

Uso do zoneamento ambiental do Médio Rio Grande na sub-bacia hidrográfica do Ribeirão Bocaina - Passos/MG

Este trabalho é parte integrante do Projeto Grande Minas - União pelas Águas, que realizou o Zoneamento Ambiental das Sub-bacias Hidrográficas dos Afluentes Mineiros do Médio Rio Grande. Após a obtenção dos produtos finais do zoneamento, entra-se agora, na fase de “Implementação”, ou seja, de sua aplicação direta para contribuir no processo de gestão dos recursos hídricos das sub-bacias hidrográficas da área de estudo. Neste trabalho estuda-se, especificamente, a sub-bacia hidrográfica do Ribeirão Bocaina, considerada uma das 34 sub-bacias que envolvem a Bacia Hidrográfica dos Afluentes Mineiros do Médio Rio Grande e situa-se no município de Passos-MG, possuindo uma área de 457,9 km². O trabalho busca dar uma contribuição para a gestão dos recursos hídricos nesta sub-bacia, que vem sofrendo com a degradação do seu recurso hídrico. O objetivo é disponibilizar instrumentos cartográficos para subsidiar a gestão dos recursos hídricos e, com isto, contribuir com a sua preservação e uso sustentável. A sistemática metodológica envolve uma análise dos aspectos legais da área de estudo; a construção de um Banco de Dados Digital georreferenciado com informações sobre os meios físico, biótico e socioeconômico da sub-bacia e a produção de uma carta derivada, de cunho interpretativo e de fácil leitura, que possa ser utilizada diretamente pelo gestor público nas tomadas de decisões. A base digital produzida conta com uma série de mapas digitais, dentre eles: mapas climáticos, de solos, declividades, geomorfológico, geológico, de sistemas aquíferos, hidrográfico, uso e ocupação do solo. Com relação à carta derivada, destaca os terrenos que apresentam maior predisposição à alterações diretas nos recursos hídricos.

Tab. 1: Zircon isotopic data and rock ages from the Antarctic Peninsula

Morphological and U-Pb isotope studies on sedimentary zircons reflect the orogenic evolution of their former host rocks. The orogenic history of detrital zircons from the Trinity Peninsula Formation (TPF) defines the former geological surrounding of the sedimentation basin of the TPF. Same few weil rounded, polycyclic zircons of Precambrian age and Cambrian overprint give hints for an old cratonic source rock. Because of their very low frequency compared with euhedral types, the contribution of an cratonic shield area to the bulk of the sedimentary debris is neglectable low. Euhedral zircons of granitoid origin and Carboniferous age indicate a derivation from an area of widespread Carboniferous intrusions. Except for southern South America and unsurveyed regions in the Antarctic Peninsula itself, no region could deliver zircons with a Carboniferous age record. The only acceptable explanation for the origin of these zircons is a position of the Antarctic Peninsula during the sedimentation of the TPF approximately southwest of southern South America.

Hyperspace geography: Visualizing fitness landscapes beyond 4D

Human perception is finely tuned to extract structure about the 4D world of time and space as well as properties such as color and texture. Developing intuitions about spatial structure beyond 4D requires exploiting other perceptual and cognitive abilities. One of the most natural ways to explore complex spaces is for a user to actively navigate through them, using local explorations and global summaries to develop intuitions about structure, and then testing the developing ideas by further exploration. This article provides a brief overview of a technique for visualizing surfaces defined over moderate-dimensional binary spaces, by recursively unfolding them onto a 2D hypergraph. We briefly summarize the uses of a freely available Web-based visualization tool, Hyperspace Graph Paper (HSGP), for exploring fitness landscapes and search algorithms in evolutionary computation. HSGP provides a way for a user to actively explore a landscape, from simple tasks such as mapping the neighborhood structure of different points, to seeing global properties such as the size and distribution of basins of attraction or how different search algorithms interact with landscape structure. It has been most useful for exploring recursive and repetitive landscapes, and its strength is that it allows intuitions to be developed through active navigation by the user, and exploits the visual system's ability to detect pattern and texture. The technique is most effective when applied to continuous functions over Boolean variables using 4 to 16 dimensions.

MBORAYU, O ESPÍRITO QUE NOS UNE: UM CONCEITO DA ESPIRITUALIDADE GUARANI

Neste texto trato de um conceito da espiritualidade do povo Guarani que é o Mborayu , a força-espírito: que integra e desintegra os elementos que compõem o Ñande Reko (a maneira de ser Guarani); que aglutina ou dispersa os elementos e os corpos (rete kwere) que compõem o indivíduo; que catalisa ou dilui Ñamandu (a natureza de todos os mundos). O Mborayu também abarca o Aywu (a palavra) que nomina e organiza uma compreensão do Ñeem (termo-idéia), do espírito das coisas, que não é a realidade (ete), porque a última realidade (opa wa erã) pertence a Ñemi Guaxu (o grande mistério). Nesse tom, percorro neste estudo, todo um universo da mítica e da espiritualidade Guarani, porque o Mborayu reúne todos os elementos que compõem Ñamandu, em uma totalidade inacabada e, por sua força de atração a vida (ikowe) é gerada, encontrando, no entanto, sua última expressão, na morte (mano), na desintegração, seu derradeiro sentido.(AU)

Magnetic drive system for a new centrifugal rotary blood pump

The purpose of this investigation was to design a novel magnetic drive and bearing system for a new centrifugal rotary blood pump (CRBP). The drive system consists of two components: (i) permanent magnets within the impeller of the CRBP; and (ii) the driving electromagnets. Orientation of the magnets varies from axial through to 60° included out-lean (conical configuration). Permanent magnets replace the electromagnet drive to allow easier characterization. The performance characteristics tested were the axial force of attraction between the stator and rotor at angles of rotational alignment, Ø, and the corresponding torque at those angles. The drive components were tested for various magnetic cone angles, ?. The test was repeated for three backing conditions: (i) non-backed; (ii) steel-cupped; and (iii) steel plate back-iron, performed on an Instron tensile testing machine. Experimental results were expanded upon through finite element and boundary element analysis (BEM). The force/torque characteristics were maximal for a 12-magnet configuration at 0° cone angle with steel-back iron (axial force = 60 N, torque = 0.375 Nm). BEM showed how introducing a cone angle increases the radial restoring force threefold while not compromising axial bearing force. Magnets in the drive system may be orientated not only to provide adequate coupling to drive the CRBP, but to provide significant axial and radial bearing forces capable of withstanding over 100 m/s2 shock excitation on the impeller. Although the 12 magnet 0° (?) configuration yielded the greatest force/torque characteristic, this was seen as potentially unattractive as this magnetic cone angle yielded poor radial restoring force characteristics.

Coccolithophore abundance and biometry in the South China Sea, 2014

Coccolithophore contributions to the global marine carbon cycle are regulated by the calcite content of their scales (coccoliths), and the relative cellular levels of photosynthesis and calcification. All three of these factors vary between coccolithophore species, and with response to the growth environment. Here, water samples were collected in the northern basin of the South China Sea (SCS) during summer 2014 in order to examine how environmental variability influenced species composition and cellular levels of calcite content. The vertical structure of the coccolithophore community was strongly regulated by mesoscale eddies. All living coccolithophores produced within the euphotic zone (1 % of surface irradiance), and Florisphaera profunda was a substantial coccolithophore and coccolith-calcite producer in the Deep Chlorophyll-a Maximum (DCM), especially in most oligotrophic anti-cyclonic eddy centers. Placolith-bearing coccolithophores, plus F. profunda, and other larger and numerically rare species made almost equal contributions to coccolith-based calcite in the water column. For Emiliania huxleyi biometry measurements, coccolith size positively correlated with nutrients, and it is suggested that coccolith length is influenced by nutrient and light related growth rates. However, larger sized coccoliths were related to low pH and calcite saturation, although it is not a simple cause and effect relationship. Genotypic or ecophenotypic variation may also be linked to coccolith size variation.

Estudo in silico das interações da protease NS3-NS2B de DENV-2 com o inibidor peptídico Bz-nKRR-H com finalidades terapêuticas

Dengue virus is an important patogen that causes Dengue desease in all world, and belongs to Flavivirus gender. The virus consists of enveloped RNA with a single strand positive sense, 11Kb genome. The RNA is translated into a polyprotein precursor, wich is cleaved into 3 structural proteins (C, prM e E) and 7 non-structural proteins (NS1, NS2A, NS2B, NS3, NS4A, NS4B e NS5). The NS3 is a multifunctional protein, that besides to promote the polyprotein precursor cleavage, also have NTPase, helicase and RTPase activity. The NS3 needs a hydrophilic segment of 40 residues from the transmembrane NS2B protein (who acts like cofator) to realize this functions. Actually, there's no vacines available on the market, and the treatment are just symptomatic. The tetrapeptide inhibitor Bz-Nle-Lys-Arg-Arg-H (Ki de 5,8-7,0 M) was showed as a potent inhibitor μ for NS3prot in Dengue virus. That is a inteligent alternative to treat the dengue desease. The present work aimed analyse the interactions of the ligand bounded to the activity site to provid a clear and depth vision of that interaction. For this purpouse, it was conducted an in silico study, by using quantum mechanical calculations based on Density Functional Theory (DFT), with Generalized Gradient approximation (GGA) to describe the effects of exchange and correlation. The interaction energy of each amino acid belonging to the binding site to the ligand was calculated the using the method of molecular fragmentation with conjugated caps (MFCC). Besides energy, we calculated the distances, types of molecular interactions and atomic groups involved. The theoretical models used were satisfactory and show a more accurate description when the dielectric constant = 20 ε and 80 was used. The results demonstrate that the interaction energy of the system reached convergence at 13.5 A. Within a radius of 13,5A the most important residues were identified. Met49, Met84 and Asp81 perform interactions of hydrogen with the ligant. The Asp79 and Asp75 residues present high energy of attraction. Arg54, Arg85 and Lys 131 perform hydrogen interactions with the ligand, however, appear in BIRD graph having high repulsion energy with the inhibitor. The data also emphasizes the importance of residue Tyr161 and the involvement of the catalytic triad composed by Asp75, His51 and Ser135
