Atypical modulations of N170 component during emotional processing and their links to social behaviors in ex-combatants

ABSTRACT: Emotional processing (EP) is crucial for the elaboration and implementation of adaptive social strategies. EP is also necessary for the expression of social cognition and behavior (SCB) patterns. It is well-known that war contexts induce socio-emotional atypical functioning, in particular for those who participate in combats. Thus, ex-combatants represent an ideal non-clinical population to explore EP modulation and to evaluate its relation with SCB. The aim of this study was to explore EP and its relation with SCB dimensions such as empathy, theory of mind and social skills in a sample of 50 subjects, of which 30 were ex-combatants from illegally armed groups in Colombia, and 20 controls without combat experience. We adapted an Emotional Recognition Task for faces and words and synchronized it with electroencephalographic recording. Ex-combatants presented with higher assertion skills and showed more pronounced brain responses to faces than Controls. They did not show the bias toward anger observed in control participants whereby the latter group was more likely to misclassify neutral faces as angry. However, ex-combatants showed an atypical word valence processing. That is, words with different emotions yielded no differences in N170 modulations. SCB variables were successfully predicted by neurocognitive variables. Our results suggest that in ex-combatants the links between EP and SCB functions are reorganized. This may reflect neurocognitive modulations associated to chronic exposure to war experiences

Possibilities of the use of CeBr3 scintillation detectors for the measurement of the content of radionuclides in samples for environmental monitoring

The investigation of radioactivity in samples is an application of gamma-ray spectrometry dealing with low and very low level gamma-ray activities of different isotopes. Gamma-ray spectrometry performed in the framework of radiological environmental monitoring may be done after selective sampling processes or after a chemical purification of a sample. Both cases imply that only some specific radionuclides should contribute to the obtained spectrum. Gamma-ray spectrometry performed with medium energy resolution detectors may allow the possible distinction of their photopeaks. Therefore, a cerium bromide (CeBr3) detector can be particularly attractive for routine tasks in radiological environmental monitoring as it has a high efficiency, medium energy resolution and it can work at room temperature. This study describes the conditions under which a CeBr3 detector can serve for some routine analysis in radiological analysis of samples collected in the environment or collected by airsamplers in environmental radiological monitoring programmes

Quantification of the influence of the C, Cr and P contents on the permeability of hydrogen through Fe alloys

[EN] Ferritic-martensitic steels are candidate materials for blanket structural components of future thermonuclear fusion reactors. However, the tritium inventory that can be retained in different components of the reactor and its ability to migrate through the walls of any material may affect the correct operation of any fusion device. Therefore, the permeability of hydrogen isotopes through ferritic-martensitic steels, which depends on its metallurgical composition, becomes a key issue. The European Fusion Development Agreement (EFDA) supplied 9 Fe alloys with controlled chemical alloying element contents and microstructure. The main alloying elements were C, Cr and P and they appeared in various concentrations in the 9 alloys. They were experimentally analyzed by means of the gas evolution permeation technique with temperatures ranging from 423 K to 823 K and for high purity hydrogen loading pressures ranging from 5.0 x 102 Pa to 1.5 x 105 Pa. The transport regime turned out to be diffusive and it was studied in depth, so that the permeability of each alloy was characterized by an Arrhenius-type regression for the aforementioned temperature range. This work summarizes all the experimental measurements carried out for the permeability of hydrogen through the 9 alloys. It provides a quantification of the influence of the composition of the alloy on this transport parameter, posing different mathematical expressions for the variation of the permeability as a function of the contents of C, Cr and P.This work has been carried out in the framework of research projects funded by the Spanish Ministry of Science and Innovation (MEC08/98) , the University of the Basque Country (UPV/EHU-EHU08-34) and the European Fusion Development Agreement (EFDA MAT-REMEV) .

Meteorological Factors Controlling 7Be Activity Concentrations in the Atmospheric Surface Layer in Northern Spain

This work presents the analysis of weekly 7Be activity concentrations in the air measured in Bilbao (northern Spain) by collecting aerosols in filters over a ten years period (2009–2018). 7Be level is in the 0.35–7.3 mBq/m3 range, with a mean of 3.20 ± 1.12 mBq/m3. The trend, cycle, seasonal and monthly variability are evaluated using time series analysis techniques. The results indicate the impact of sunspots (24th solar cycle) on interannual 7Be activity concentrations, and a significant seasonal and monthly variation, with maximum concentrations occurring in spring-summer and minimum in the winter. The correlation of different 7Be ranges with local meteorological parameters, such as precipitation, temperature, relative humidity, and pressure, is also addressed, with precipitation having the greatest impact on 7Be activity values. The analysis of synoptic airflows, by calculating the back-trajectory clusters, and local winds at surface level reveals the important influence of the arrival of slow northwest Atlantic flows and the development of breezes on reaching high 7Be activity concentrations in this area

Five Years (2014–2018) of Beta Activity Concentration and the Impact of Synoptic and Local Meteorological Conditions in Bilbao (Northern Spain)

The aim of this paper is to statistically characterize gross beta activity concentrations in ground-level air in Bilbao (northern Spain) by analysing five years (2014–2018) worth of weekly measurements in aerosols collected in filters to analyse the impact of local meteorological parameters on concentrations. In addition, synoptic meteorological scenarios associated with anomalous beta surface activity concentrations were identified. Over this five-year period, beta activity concentrations ranged from 35.45 µBq/m3 to 1778 µBq/m3 with a mean of 520.12 ± 281.77 µBq/m3. A positive correlation was found with the alpha concentrations (0.67), with an average of 0.138 for the alpha/beta ratio, and a low correlation was found with 7Be (0.16). Statistical analysis identified a seasonal component in the time series, increasing, on average, beta activity concentrations from winter to autumn. The highest beta activity concentrations were measured under the arrival of southerly land winds with low wind speeds, while the wind analysis (surface winds and air masses) of two different seasonal periods (autumn 2015 and winter 2017) have highlighted how small variations in synoptic and local winds highly influence beta activity concentrations. These results are relevant to understand the meteorological factors affecting beta activity concentrations in this area and hence to define meteorological scenarios that are in favour to high/anomalous surface activity concentrations that are harmful to the environmental and public health

Joint use of piezometric surfaces and chemical and isotopic tracers to identify recharge areas in arid environments: Agrelo fan area, Mendoza province, Argentina

Si bien el área del Abanico de Agrelo cuenta con numerosos estudios de carácter hidrogeológico por su importancia desde el punto de vista de la recarga del acuífero de Cuenca Norte de Mendoza, aún existen incertidumbres por resolver. El objetivo de este trabajo es incrementar la información disponible para actualizar y mejorar el modelo conceptual del acuífero, reconociendo las posibles zonas de recarga a partir del uso de piezometría y datos hidroquímicos e isotópicos. Para ello se realizó la recopilación de antecedentes y se redefinió la dinámica de flujo del acuífero estudiado. Sobre la base de estos antecedentes, se planificó y llevó a cabo un muestreo hidroquímico e isotópico con el fin de corroborar la dinámica hidrológica. Los resultados indican que el flujo predominante del sistema tiene sentido NO-SE y que, si bien el río Mendoza es la principal fuente de recarga, podrían existir otras áreas de aporte. Los datos hidroquímicos corroboran la dinámica, mostrando un enriquecimiento paulatino de sales en el sentido del flujo. El patrón hidroquímico subterráneo es similar al del río, pero con valores de conductividad menores en la zona proximal, indicando posible mezcla de aguas a partir de otra fuente de recarga adicional. El modelo conceptual resultante considera que el sistema hidrogeológico del Abanico de Agrelo se extiende hacia ambas márgenes del río Mendoza y que el río no constituye un borde del sistema acuífero en sí, ya que funciona como una zona de recarga. Además, muestra la existencia de fuentes de recarga adicionales al río.Although there are numerous hydrogeological papers on the Abanico de Agrelo area due to its importance from the point of view of recharge to the Mendoza Northern Basin, many uncertainties still remain to be sol-ved. The aim of this study is to obtain new data to update and improve the conceptual model of the aquifer. For this purpose, we have carried out a desktop review of the previous data and the aquifer dynamics have been redefined. Based on this information, a hydrochemical and isotopic sampling was carried out in order to confirm the hydrogeological dynamics. Our results indicate that the main flow of the aquifer is NW-SE and that although the river is the main source of recharge, there could be other input areas. The hydrochemical data confirm this dynamic, showing a gradual enrichment of salts in the flow direction.The hydrochemical underground pattern is similar to that of the river, but it shows lower conductivity values ​in the nearby areas, in-dicating a probable mixture of water from another recharge source.The resulting conceptual model considers that the hydrogeological system of the Abanico de Agrelo extends to both banks of the Mendoza River and that the river is not an edge of the aquifer itself as it works as an indirect recharge area. The existence of ad-ditional recharge sources is also proposed in this paper.Fil: Tognoli, Pabla Natalia. Universidad Nacional de Cuyo. Facultad de Ingeniería.
