Contenido de Cadmio y Plomo en tejido de Hígado y Riñón en el Jote de Cabeza Colorada Cathartes aura (Linneo, 1758) de Chañaral, Desierto de Atacama, Chile

Indexación: Web of Science; ScieloThe Atacama region, Chile, presents one of the highest levels of mining exploitation of the country, which leads to high levels of contamination from mine tailings and other related environmental liabilities. One of the most complex situations occurred in the Chañaral city, north of Chile, where for over 50 years mine tailings were dumped on the coast, causing severe damage in the ecosystem. To evaluate the effects on terrestrial biota, we analyzed the concentration of cadmium and lead in tissues of Turkey Vulture (Cathartes aura). The results indicate that accumulation of cadmium in kidney was 10.31 μg/g (SD 8.00, range 0.27 to 20.73 μg/g) while in the liver was 5.24 μg/g (SD 8.00, range 0.49 to 19.70). There values are very high when compared to data for other birds with similar ecological role. In relation to the lead, concentration in liver was 0.86 μg/g (SD 2.03, range 0.15 - 7.90), while in kidney was 1.05 μg/g (DS 2.54, range 0.044 to 9.86), values considered within the normal range. It is interesting to analyze from the perspective of the availability of these metals in the mining tailings, where lead (1.57 to 21.2 μg/g) presented higher levels than cadmium (0.061 to 1.085 μg/g). The difference between organs may be related to the role of metallothionein. We discuss the role of Turkey Vulture as a bioindicator of environmental liabilities.La Región de Atacama, Chile, presenta uno de los mayores niveles de explotación minera del país, el cual a su vez genera altos niveles de contaminación por relaves mineros y otros pasivos ambientales relacionados. Una de las más complejas situaciones ocurrió en la ciudad de Chañaral, norte de Chile, donde fueron liberados relaves mineros a sus costas por sobre 50 años, causando graves daños en el ecosistema. Para evaluar los efectos en la biota terrestre, nosotros analizamos la concentración de Cadmio y Plomo en tejidos del Jote de Cabeza Colorada (Cathartes aura). Los resultados indican que la acumulación de Cadmio en el Riñón fue 10,31 μg/g (DS 8,00, rango 0,27 a 20,73 μg/g) mientras en el Hígado fue 5,24 μg/g (DS 8,00, rango 0,49 a 19,70). Estos valores son muy altos si se compara con datos de otras aves de similar rol ecológico. En relación al Plomo, la concentración en Hígado fue de 0,86 μg/g (DS 2,03, rango 0,15 a 7,90), mientras que en Riñón fue de 1,05 μg/g (DS 2,54, rango 0,044 a 9,86), valores considerados dentro del rango normal. Estos resultados son interesantes de analizar desde la perspectiva de la disponibilidad de estos metales en el relave minero, donde el Plomo (1,57 a 21,2 μg/g) presentó mayores niveles que el Cadmio (0,061 a 1,085 μg/g). La diferencia entre órganos puede ser relacionado al rol de las metalotioneinas. Discutimos el rol del Jote de Cabeza Colorada como bioindicador de contaminaciones ambientales.http://ref.scielo.org/86hcb

Después de la inundación, el desastre continúa: fraccionamiento nuevo mirador en Chilpancingo, Guerrero

El presente ensayo aborda el tema del desastre originado en la ciudad de Chilpancingo de los Bravo, capital del estado de Guerrero, en donde 1,295 viviendas fueron afectadas por los fenómenos meteorológicos Íngrid y Manuel, en septiembre de 2013. En el documento se analizan las acciones para reparar los daños, realizadas por el Estado, tomando como caso de estudio el Fraccionamiento Nuevo Mirador, un conjunto habitacional creado ex profeso para alojar a los afectados por el desastre. Considerando que los desastres no son producto de las manifestaciones de la naturaleza, sino que el causante principal es el ser humano, quien al intervenir el hábitat natural de manera inadecuada fomenta el riesgo de provocarlo, en este texto se hace una reflexión histórica, crítica y teórica sobre acciones implementadas por diversos actores políticos y sociales vinculados con el ordenamiento territorial de Chilpancingo, la segunda ciudad más poblada de la entidad (la primera es Acapulco, que cuenta con 725,549 habitantes en su área urbana),1 la cual se encuentra ubicada en una zona altamente sísmica, y en las inmediaciones del corredor de huracanes que anualmente afectan la costa del Pacífico mexicano, además de ser la sede económica-administrativa del gobierno estatal a la cual diariamente arriban miles de personas en busca de solucionar sus demandas sociales. Con el tiempo gran parte de esta población demandante se ha asentado en diversas partes de la ciudad, la mayoría no aptas para el desarrollo urbano por ser zonas con altas pendientes, susceptibles a deslaves e inundaciones

Association between Level of Empathy, Attitude towards Physical Education and Victimization in Adolescents: A Multi-Group Structural Equation Analysis

[Abstract] Currently, there is a problem related to violence and tolerance towards violence, and the levels of empathy of the subjects can affect this, in addition to the practice of physical activity. The present study sought to define and contrast an explanatory model of victimization, empathy and attitude towards physical education, and to analyze the existing relationships between these variables as a function of engagement with physical activity. A total of 2388 adolescents from Spain participated in this research. The sample was made up of both sexes (43.39% males and 56.61% females), with ages reported between 11 and 17 years (M = 13.85; SD = 1.26). Empathy (TECA), attitude towards physical education (CAEF) and victimization (EV) were measured. A multi-group structural equation model was developed, which showed excellent fit to the empirical data (x² = 559.577; DF = 38; p < 0.001; comparative fit index (CFI) = 0.957; normalized fit index (NFI) = 0.954; incremental fit index (IFI) =0.957; root mean squared error of the mean (RMSEA) = 0.054). A direct positive relationship exists between affective and cognitive empathy. A positive association was found between motivational climate and engagement in physical activity. With regards to victimization, the verbal dimension obtained the highest correlation score, followed by the relational and physical dimensions. In the case of adolescents who regularly engaged in physical activity, the verbal and physical dimensions presented the weakest correlations, whilst the relational dimension was the most strongly associated in the case of sedentary adolescents. The main conclusions of the present study it is that the relationship between affective empathy and cognitive empathy is positive and direct, however, this relationship is slightly stronger and differentiated in sedentary adolescents than in those who practice physical activity on a regular basis

Adaptive Pitch Controller of a Large-Scale Wind Turbine Using Multi-Objective Optimization

This paper deals with the control problems of a wind turbine working in its nominal zone. In this region, the wind turbine speed is controlled by means of the pitch angle, which keeps the nominal power constant against wind fluctuations. The non-uniform profile of the wind causes tower displacements that must be reduced to improve the wind turbine lifetime. In this work, an adaptive control structure operating on the pitch angle variable is proposed for a nonlinear model of a wind turbine provided by FAST software. The proposed control structure is composed of a gain scheduling proportional–integral (PI) controller, an adaptive feedforward compensation for the wind speed, and an adaptive gain compensation for the tower damping. The tuning of the controller parameters is formulated as a Pareto optimization problem that minimizes the tower fore-aft displacements and the deviation of the generator speed using multi-objective genetic algorithms. Three multi-criteria decision making (MCDM) methods are compared, and a satisfactory solution is selected. The optimal solutions for power generation and for tower fore-aft displacement reduction are also obtained. The performance of these three proposed solutions is evaluated for a set of wind pattern conditions and compared with that achieved by a classical baseline PI controller

Introduction: Triathlon is a sport that combines three different disciplines. The most widespread triathlon is the Olympic modality, which is used in the Olympic Games, consisting of swimming 1.5 km, cycling 40 km and running 10 km. Aims: To determine the influence of the duration and order of the different stages on the final result of the men’s triathlon race in London 2012 Olympic Games. Method: Data from 54 athletes who finished was analysed. Results and conclusions: The final result is not determined neither by the order of the stages, nor by their duration, the least influential discipline being Bike without correlation with result; however being the most time consuming, 53.76%; the most influential stage was Run with rs = 0.913; and p = 0.000; and R2 =0 .833, with 28.93% duration

MVPAlab: A machine learning decoding toolbox for multidimensional electroencephalography data

This research was supported by the Spanish Ministry of Sci- ence and Innovation under the PID2019–111187GB-I00 grant, by the MCIN/AEI/10.13039/50110 0 011033/ and FEDER “Una manera de hacer Europa’’ under the RTI2018-098913-B100 project, by the Consejería de Economía, Innovación, Ciencia y Empleo (Junta de Andalucía) and FEDER under CV20-45250, A-TIC-080-UGR18, B- TIC-586-UGR20 and P20-00525 projects. The first author of this work is supported by a scholarship from the Spanish Ministry of Science and Innovation (BES-2017–079769). Funding for open ac- cess charge: Universidad de Granada / CBUA. The sample EEG dataset was extracted from an original experiment previously ap- proved by the Ethics Committee of the University of Granada.Background and Objective: The study of brain function has recently expanded from classical univariate to multivariate analyses. These multivariate, machine learning-based algorithms afford neuroscientists extracting more detailed and richer information from the data. However, the implementation of these procedures is usually challenging, especially for researchers with no coding experience. To address this problem, we have developed MVPAlab, a MATLAB-based, flexible decoding toolbox for multidimensional electroencephalography and magnetoencephalography data. Methods: The MVPAlab Toolbox implements several machine learning algorithms to compute multivariate pattern analyses, cross-classification, temporal generalization matrices and feature and frequency contri- bution analyses. It also provides access to an extensive set of preprocessing routines for, among others, data normalization, data smoothing, dimensionality reduction and supertrial generation. To draw statisti- cal inferences at the group level, MVPAlab includes a non-parametric cluster-based permutation approach. Results: A sample electroencephalography dataset was compiled to test all the MVPAlab main function- alities. Significant clusters (p < 0.01) were found for the proposed decoding analyses and different config- urations, proving the software capability for discriminating between different experimental conditions. Conclusions: This toolbox has been designed to include an easy-to-use and intuitive graphic user interface and data representation software, which makes MVPAlab a very convenient tool for users with few or no previous coding experience. In addition, MVPAlab is not for beginners only, as it implements several high and low-level routines allowing more experienced users to design their own projects in a highly flexible manner.Spanish Government PID2019-111187GB-I00 BES-2017-079769MCIN/AEIFEDER "Una manera de hacer Europa'' RTI2018-098913-B100Junta de AndalucíaEuropean Commission CV20-45250 A-TIC-080-UGR18 BTIC-586-UGR20 P20-00525Universidad de Granada/CBU

A multi-class classification model with parametrized target outputs for randomized-based feedforward neural networks.

Randomized-based Feedforward Neural Networks approach regression and classification (binary and multi-class) problems by minimizing the same optimization problem. Specifically, the model parameters are determined through the ridge regression estimator of the patterns projected in the hidden layer space (randomly generated in its neural network version) for models without direct links and the patterns projected in the hidden layer space along with the original input data for models with direct links. The targets are encoded for the multi-class classification problem according to the 1-of- encoding ( the number of classes), which implies that the model parameters are estimated to project all the patterns belonging to its corresponding class to one and the remaining to zero. This approach has several drawbacks, which motivated us to propose an alternative optimization model for the framework. In the proposed optimization model, model parameters are estimated for each class so that their patterns are projected to a reference point (also optimized during the process), whereas the remaining patterns (not belonging to that class) are projected as far away as possible from the reference point. The final problem is finally presented as a generalized eigenvalue problem. Four models are then presented: the neural network version of the algorithm and its corresponding kernel version for the neural networks models with and without direct links. In addition, the optimization model has also been implemented in randomization-based multi-layer or deep neural networks.Funding for open access charge: Universidad de Málaga / CBU

Exergames e deficiência

Introducción: En la actualidad, las nuevas tecnologías están cambiando la forma de ver el mundo, aunque cuentan con diversas implicaciones negativas derivadas de su mal uso. Dentro del mundo de los videojuegos se encuentran los Exergames, que son un tipo de videojuegos que implican el movimiento corporal como medio de control, por lo que se sustituye el concepto de videojuego tradicional que se asocia a conductas sedentarias por un juego virtual mucho más activo. En sus inicios los Exergames pretendías ser una herramienta que fomentase la práctica de actividad física, pero fueron utilizando una tecnología cada vez más compleja, que permitió la creación de un sinfín de posibilidades. Debido al potencial de los Exergames, se comenzó a investigar en diferentes campos, como el de la medicina y rehabilitación o educación entre otros, comprobando las múltiples posibilidades de este tipo de videojuegos. Se comenzó a utilizar estos dispositivos con personas con discapacidad, utilizándolos como apoyo para sus terapias e investigando su funcionalidad para hacer más accesibles la tecnología a personas discapacitadas.Currently, new technologies are changing the way people see the world, although they have different negative implications derived from their misuse. Within the world of videogames are the Exergames, which are a type of videogames that involve body movement as a means of control, so the concept of traditional videogame that is associated with sedentary behavior is replaced by a much more active virtual game. In its beginnings, the Exergames pretended to be a tool that fostered the practice of physical activity, but they were using an increasingly complex technology, which allowed the creation of endless possibilities. Due to the potential of the Exergames, research began in different fields, such as medicine and rehabilitation or education among others, proving the multiple possibilities of this type of videogames. It began to use these devices with people with disabilities, using them as support for their therapies and investigating their functionality to make the technology more accessible to people with disabilities.Atualmente, as novas tecnologias estão mudando a maneira como as pessoas vêem o mundo, embora tenham diferentes implicações negativas derivadas do uso indevido.
