Morphology of copper deposits obtained by metallic electrodeposition

Electrochemical deposition of copper from copper nitrate aqueous electrolyte on graphite substrate was investigated at current densities between 0.03 mA/cm2 - 1.36 mA/cm2 and in the voltage range of 3 V to 15 V. The surface morphology and elemental composition of the resultant deposit were characterized by electron microprobe analysis (EMPA). These images illustrate the influence of current density on the shape of copper electrodeposited on the electrode surface. Rods, polyhedral bodies, pentagonal pyramids, dendritics, spiked spheres or cauliflower-like shapes are observed depending on the electrodeposition conditions.Fil: González Mercado, Griselda Verónica.

The Informational Consequences of Populism: Social Media News Use and "News Finds Me" Perception

Prior studies have theorized a positive association between people’s populist attitudes and an increased use of social media to consume news, which will be mainly driven by individuals' engagement with news that reflects their people-centered, anti-elitist, and Manichean understanding of politics. However, such general connection remains elusive. This research seeks to further clarify this strand of the literature by incorporating people’s belief that important political information will find them without actively seeking news - "News Finds Me" perception (NFM). For that, we use online survey data from two European countries that differ regarding the ideological political supply side of populism (Italy and Portugal). The main results suggest that citizens who hold stronger populist attitudes will also develop stronger NFM. Furthermore, findings reveal a mediating effect of social media news use on the effects of populist attitudes over NFM. That is, those who hold stronger populist attitudes tend to use social media to get exposed to public affairs news more often, which in turn explains the development of the NFM. These results emphasize the importance of systematically exploring citizens populists’ attitudes within today's social media, social networks, and complex information systems

Object detection in traffic videos: an optimized approach using super-resolution and maximal clique algorithm

Funding for open access publishing: Universidad Málaga/CBUA

Automate d lab eling of training data for improved object detection in traffic videos by fine-tuned deep convolutional neural networks

The exponential increase in the use of technology in road management systems has led to real-time vi- sual information in thousands of locations on road networks. A previous step in preventing or detecting accidents involves identifying vehicles on the road. The application of convolutional neural networks in object detection has significantly improved this field, enhancing classical computer vision techniques. Al- though, there are deficiencies due to the low detection rate provided by the available pre-trained models, especially for small objects. The main drawback is that they require manual labeling of the vehicles that appear in the images from each IP camera located on the road network to retrain the model. This task is not feasible if we have thousands of cameras distributed across the extensive road network of each nation or state. Our proposal presented a new automatic procedure for detecting small-scale objects in traffic sequences. In the first stage, vehicle patterns detected from a set of frames are generated automatically through an offline process, using super-resolution techniques and pre-trained object detection networks. Subsequently, the object detection model is retrained with the previously obtained data, adapting it to the analyzed scene. Finally, already online and in real-time, the retrained model is used in the rest of the traffic sequence or the video stream generated by the camera. This framework has been successfully tested on the NGSIM and the GRAM datasets.Funding for open access charge: Universidad de Málaga/CBU

Percepción de la Calidad en Atención de las Usuarias en el Servicio de Ginecología y Obstetricia de un Hospital Público de alta Especialidad en Veracruz

Background: It is known that measuring the perception of the quality of care in a hospital has become a growing and important indicator of the efficiency of the health system; however, so far, Mexico has not set a precedent for it. Objective: To report the results obtained in order to evaluate its importance and impact. Material and Methods: A qualitative cohort, prospective longitudinal study was carried out in the High Specialty Hospital of the Secretary of Health and Assistance (SSA) of the state of Veracruz, in the different areas of the gynecology and obstetrics service (GYO), using the surveys provided by the official website of the State Government:  http://www.calidad.salud.gob.mx/site/calidad/encuesta_satisfaccion_trato_digno.html as a measurement instrument. Unit of Analysis: 450 people following pertinent inclusion and exclusion criteria, with a confidence level of 99% and a confidence limit of 1.7%. Discussion: Given the growing demand for health services by users, it is imperative that both public and private institutions are up to the task, both in terms of quantity and quality of human capital. Conclusions: we consider it necessary to generate analysis and reflection devices that redefine the model of relationship between professionals and patients, considering the political, social and cultural variables in which this relationship is formed.Antecedentes: Se sabe que, medir la persepción de la calidad en la atencion de un nosocomio se ha convertido en un indicador creciente e importante de la eficiencia del sistema de salud, sin embargo hasta el momento, México no ha marcado antecedente del mismo.

Caracterización productiva y territorial de las ganaderías de bovino de leche en Cantabria, según el contenido de forraje verde en la dieta (póster)

En los últimos años, están apareciendo en el mercado leche en la que se indica “de pastoreo” o “de pasto”, debido al interés creciente de la sociedad hacia productos más saludables y respetuosos con el medioambiente. El objetivo de este trabajo es profundizar en la relación entre las características territoriales de las ganaderías de bovino de leche y su manejo alimentario. Se clasificaron 99 ganaderías en función del porcentaje de forraje verde (FV) en la dieta -de primavera- de las vacas en lactación (No pasto <25% FV; Pasto ≥25% FV). Como variables se incluyeron el porcentaje de materia seca de los distintos componentes de la dieta, las principales características productivas y la información territorial contenida en la base de datos oficial SIA (Sistema integrado de ayudas) para 41 variables territoriales. Las ganaderías pertenecientes al modelo en base a pasto (≥25% FV) constituyen el 33% y presentan una menor dimensión productiva, carga ganadera y consumo de concentrado, con una mayor dedicación al pastoreo. Además, presentan mayor altitud de las parcelas, parcelas de mayor dimensión, más homogéneas y con mejor geometría, pero también un suelo de baja capacidad de uso agrícola. Este trabajo abre la posibilidad a analizar el potencial productivo y territorial de Cantabria para la producción de leche en base a pasto, como estrategia de valorización de los sistemas extensivos de producción de leche ligada al territorio

Physiotherapists’ knowledge on the provision of physiotherapy to people with mental illness. A study from Paraguay

Introduction: Physiotherapy improves the quality of life in people with mental disorders through the optimization of their physical and mental health. This study aimed to determine the knowledge of physiotherapists about the provision of Physiotherapy services to people with mental disorders, about the role of Physiotherapy in the treatment of physical illnesses of mentally ill persons and in the treatment of the mental disorder itself. Methodology: A descriptive, observational, cross-sectional, and prospective study was conducted. 187 physiotherapists practicing in Paraguay, of both sexes, were surveyed. The data collection instrument was a Spanish version of the survey used by Andrew et al., which was adapted. Results: 46.52% of physiotherapists stated that Physiotherapy is useful to manage the physical symptoms of people with mental disorders. 55.61% reported that they needed more information and/or training on managing physical conditions affecting these people. 75.94% declared that they were aware that Physiotherapy can be used as treatment for some mental disorders, mainly as an adjuvant treatment to both pharmacotherapy and psychotherapy (54.55%). Participants scored anxiety disorders (23.88%), major depression disorder (21.99%) and Alzheimer's disease (21.48%) as those conditions that could most benefit from a physiotherapeutic intervention. Also, 21.93% of the respondents reported the need of more information on how to interact and communicate with people with mental disorders. Conclusion: There are gaps in the knowledge of physiotherapists in Paraguay about the provision of Physiotherapy to people with mental disorders. An adequate training and education of physiotherapists on mental illness is encouraged

Mulching treatments favour the recovery of ecosystem multifunctionality after a large wildfire in Northwest Spain

[EN] Wildfires are a widespread phenomenon in forests across the Mediterranean Basin but have increased in risk and severity in recent decades. Post-fire treatments are measures that help recover burned vegetation and their functionality but to what extent they also help recover soil functionality is currently unknown. The main objective of this study was to assess the effect of post-fire treatments on ecosystem multifunctionality after a large wildfire in the Cabrera mountain range in 2017 (NW Spain) where close to 10000 Ha of forest were burnt. At the end of 2017 and during 2018, the administration applied different post-fire treatments in high fire severity affected areas: i) straw mulching, ii) woody debris and iii) subsoiling and iv) mechanical hole afforestation. In each treatment, we established ten 2 x 2 m plots and ten adjacent untreated burned plots and collected a composite soil sample from each plot four years after the fire (2021). We calculated regulating services as the standardized mean of total soil organic C (climate regulation), soil water repellence (water regulation) and soil aggregation (soil protection). Supporting services were measured as the standardized mean of mineral N-NH4+ and N-NO3- and available P (soil fertility), β-glucosidase, urease and acid phosphatase (nutrient cycling) and microbial biomass (soil quality). Ecosystem multifunctionality was measured as the standardized mean of all functions measured. Application of straw mulch and woody debris increased regulating ecosystem services in relation to burned control plots. Afforestation with holes had no impact but subsoiling decreased regulating ecosystem services in relation to burned control plots. Post-fire treatments did not have any effect on supporting services. Straw mulch, Woody debris and afforestation with holes improved ecosystem multifunctionality when compared with subsoiling methods. These results show that post-fire stabilisation treatments, in particular straw mulching have a significant positive impact on regulating services and are effective measures in restoring the ecosystem multifunctionality, helping develop effective management based-decisions for the recovery of ecosystem services and functioning after large wildfiresThis research was financially supported by the Spanish Ministry of Economy and Competitiveness in the framework of the FIRESEVES (AGL2017-86075-C2-1-R) project, and by the Regional Government of Castilla and León in the framework of the WUIFIRECYL (LE005P20) projec
