Morphological and geological features of Drake Passage, Antarctica, from a new digital bathymetric model

The Drake Passage is an oceanic gateway of about 850 km width located between South America and the Antarctic Peninsula that connects the southeastern Pacific Ocean with the southwestern Atlantic Ocean. It is an important gateway for mantle flow, oceanographic water masses, and migrations of biota. This sector developed within the framework of the geodynamic evolution of the Scotia Arc, including continental fragmentation processes and oceanic crust creation, since the oblique divergence of the South American plate to the north and the Antarctic plate to the south started in the Eocene. As a consequence of its complex tectonic evolution and subsequent submarine processes, as sedimentary infill and erosion mainly controlled by bottom currents and active tectonics, this region shows a varied physiography. We present a detailed map of the bathymetry and geological setting of the Drake Passage that is mainly founded on a new compilation of precise multibeam bathymetric data obtained on 120 cruises between 1992 and 2015, resulting in a new Digital Bathymetric Model with 200 × 200 m cell spacing. The map covers an area of 1,465,000 km2 between parallels 52°S and 63°S and meridians 70°W and 50°W at scale 1:1,600,000 allowing the identification of the main seafloor features. In addition, the map includes useful geological information related to magnetism, seismicity and tectonics. This work constitutes an international cooperative effort and is part of the International Bathymetric Chart of the Southern Ocean project, under the Scientific Committee on Antarctic Research umbrella.This work was supported through projects CTM2014- 60451-C2-02/01, CTM2017-89711-C2-2/1-P and special action CTM2011-13970-E from “Ministerio de Ciencia, Innovación y Universidades” of Spain

Propuesta de intervención en homofobia interiorizada y necesidad de aprobación en hombres adultos homosexuales

43 p.A pesar del avance en las actitudes hacia la diversidad sexual por parte de la ciudadanía, aún sigue habiendo un gran estigma en torno a la homosexualidad. Este estigma ha generado sobre las personas no-heterosexuales lo que se denomina estrés de minorías, favoreciendo el desarrollo de trastornos de ansiedad, depresión o de personalidad. Estas consecuencias llevan a una interiorización de la homofobia exponiendo a las personas a un mayor nivel de necesidad a aprobación y temor a la valoración negativa de los demás, llegando a desarrollar un trastorno de fobia social. En este trabajo se propone un programa de intervención cognitivo-conductual desde la Psicología Afirmativa Gay, cuyo objetivo es la reducción de homofobia interiorizada y necesidad de aprobación en hombres adultos homosexuales.Despite the improvement on attitudes towards sexual diversity by society, there is still a great stigma around homosexuality. This stigma has made non-heterosexual people suffer from minority stress, increasing the development of anxiety, depression or personality disorders. This leads to an internalization of homophobia by exposing people to a higher level of need for approval and fear of negative assessment of others, which could eventually lead to social phobia disorder. This project settles a cognitive behavioral intervention program based on Gay Affirmative Psychology, targeting both internalized homophobia and the need for approval in adult gay men.Máster en Psicología General Sanitari

Different peach cultivars and their suitability for minimal processing

El consumo de frutas mínimamente procesadas se ha incrementado recientemente debido principalmente a su carácter de calidad fresco. Una de las principales alteraciones que limitan la vida útil de estos productos es el dorado causado por la actividad de polifenol oxidasa (PPO) sobre los compuestos fenólicos. Se seleccionaron seis cultivares de melocotón de color amarillo, Spring Lady, Royal Glory, Ruby Rich, Summer Rich, Ryan Sun y O'Henry. Los melocotones fueron higienizados y luego las muestras fueron procesadas en una habitación limpia. Las rebanadas se lavaron en agua fría del grifo, se secaron, se envasaron en atmósfera modificada y se almacenaron a 4ºC durante 9 días; se estudiaron sus parámetros de calidad y los fisicoquímicos. Se realizó el Análisis de Componentes Principales (PCA) y el estudio de correlación para evaluar la relación entre variables y cultivares. En conclusión, las variedades Spring Lady, Royal Glory y Ruby Rich fueron los cultivos que ofrecieron las frutas más adecuadas para el procesamiento de corte fresco, principalmente debido a su baja actividad BP y PPO.Consumption of minimally processed fruits has been increased lately mainly due to their fresh-like quality character¬istics. One of the major alterations that limit the shelf-life of these products is browning caused by polyphenol oxidase (PPO) activity on phenolic compounds. Six yellow-flesh peach cultivars, Spring Lady, Royal Glory, Ruby Rich, Summer Rich, Ryan Sun, and O’Henry, were selected. Peaches were hygienised and then samples were processed in a clean room. Slices were washed in cold tap water, dried, packaged in modified atmosphere, and stored at 4°C during 9 days; physicochemical and other quality parameters were studied. Principal Component Analysis (PCA) and correlation study were carried out in order to evaluate the relation between variables and cultivars. In conclusion, Spring Lady, Royal Glory, and Ruby Rich cultivars were the cultivars that offered the most suitable fruits for fresh-cut processing, mainly due to their low BP and PPO activity.Proyecto RITECA, Red de Investigación Transfronteriza de Extremadura, Centro Alentejo, cofinanciado por Fondos FEDER y el Programa Operativo de Cooperación Transfronteriza España-Portugal Gobierno de Extremadura.

Insight into the role of guanidinium and cesium in triple cation lead halide perovskites

The overall impact of the partial replacement (5–15%) of methylammonium (MA)in the MAPbI3perovskite by cesium or guanidinium (Gua) cations to fabricatethinfilms of triple cation CsxGuayMA1–x–yPbI3perovskites is studied.The structural changes are investigated by using X-ray diffraction measurementsrevealing shrinkage or expansion of the unit cell upon Cs or Gua incorporation,respectively. The optoelectronic properties are characterized with photolumi-nescence (PL) time-resolved spectroscopy and the space charge limited current(SCLC) method. Shorter PL time constants are obtained for the samples with onlyCs, while longer PL decays are measured for the perovskites containing additionalGua cation. The SCLC measurements reveal a larger density of trap states in theCsxMA1–xPbI3perovskites compared to the MAPbI3material. The PSCs fabricatedwith the different mixed cation CsxGuayMA1–x–yPbI3perovskites reveal a goodcorrelation with the measured optoelectronic properties. The power conversionefficiency (PCE) improves from an average value of 18.6% for the MAPbI3to avalue of 20.0% for the Cs0.05Gua0.05MA0.90PbI3perovskite with a champion celldelivering 21.2%. On the opposite, the PCE decreases to a value of 17.3% for thedouble cation perovskite with Cs

Behaviour of fresh cut broccoli under different modified atmosphere conditions

El brócoli recién cortado es un producto con una demanda creciente debido a su conveniencia y beneficios comprobados para la salud humana, pero es muy perecedero debido a su alta tasa de respiración. Con el fin de mantener la calidad y extender la vida útil, se llevaron a cabo dos enfoques diferentes. En primer lugar, las muestras se empaquetaron en bandejas selladas bajo una atmósfera modificada pasiva, y la mitad de ellas se calentaron con aire (48 ° C durante 3 horas). Todas las bandejas se almacenaron a 5 ° C y se analizaron a 0, 7, 14 y 21 días. Se evaluaron parámetros físico-químicos básicos, clorofila a y concentraciones b, fenólicos totales, actividad antioxidante, calidad microbiológica y sensorial. Los resultados mostraron que el brócoli tratado térmicamente mostró una calidad sensorial deficiente debido a los malos olores y no se observó un aumento en la vida útil del producto. Por esta razón, se realizó un segundo experimento utilizando atmósferas pasivas y activas modificadas (10% de O2 y 5% de CO2) y se comparó con un control en aire. Las muestras también se almacenaron a 5 ° C y se analizaron a 0, 5, 10 y 21 días. La atmósfera modificada, ya sea activa o pasiva, permitió mantener la vida útil de los flósculos de brócoli hasta 21 días, con una mayor calidad en comparación con el control, siendo la atmósfera pasiva modificada más adecuada debido a su simplicidad y menor costo.Fresh cut broccoli is a product with an increasing demand due to its convenience and proved benefits on human health, but is very perishable due to its high respiration rate. In order to maintain quality and extend shelf-life, two different approaches were carried out. Firstly, samples were packaged in sealed trays under passive modified atmosphere, and half of them were heated with air (48°C for 3 hours). All trays were stored at 5 °C, and analyzed at 0, 7, 14 and 21 days. Basic physical-chemical parameters, chlorophyll a and b concentration, total phenolics, antioxidant activity, microbiological and sensory quality were assessed. Results showed that heat treated broccoli showed poor sensory quality due to off-odors and no increase in the shelf-life of the product was observed. For this reason, a second experiment was carried using passive and active modified atmospheres (10% O2 and 5% CO2) and compared to a control in air. Samples were also stored at 5 °C and analyzed at 0, 5, 10 and 21 days. Modified atmosphere, either active or passive, allowed maintaining broccoli florets shelf-life up to 21 days, with higher quality compared to the control, being most suitable the passive modified atmosphere due to its simplicity and lower cost.• Fundación Carolina (España).

Bouguer anomalies of the NW Iberian continental margin and the adjacent abyssal plains

The NW Iberian continental margin has a complex structure, resulting from the succession of several rifting episodes close to a ridge triple junction, and a superimposed partial tectonic inversion stage. The wide-ranging physiography matches the diverse tectonic deformation domains related to its evolution. Each deformation domain has a distinctive gravity signal, so the detailed Bouguer anomaly map presented here is a good first approach to the regional study of the whole margin. Moreover, as the presented chart is a complete Bouguer anomaly map (including terrain corrections), its analysis and interpretation can be done in terms of density, geometry and depth variations below the seafloor. This map is mainly based on the dataset obtained during seven one-month surveys carried out in the frame of the Spanish Economic Exclusive Zone project, and also includes two 2 + 3/4D density models illustrating the deep structure of the marginThe marine surveys are supported by the Spanish Defense Ministry, as this is the managing body of the Spanish Exclusive Economic Zone Project (SEEZ). Additionally, the Universidad Complutense de Madrid funds travel expenses of its personnel embarking on the surveys, as does the Instituto Geológico y Minero de España in the frame of the internal project entitled ‘Plan de Investigaciones Geológicas y Geofísicas de la Zona Económica Exclusiva Española (ZEEE)
