Redes neuronales convolucionales en la detección de afecciones respiratorias de los sistemas locales de salud: una revisión sistemática entre los años 2010 y 2020

El presente trabajo de investigación se llevó a cabo con el fin de dar a conocer los enfoques de las redes neuronales convolucionales en la detección de afecciones respiratorias de los sistemas locales de salud, tomando como base la revisión de la literatura científica de los últimos 10 años. Esta investigación utilizó las indicaciones definidas por la estrategia PRISMA. Luego de hacer una búsqueda sistemática de los estudios publicados en el periodo de tiempo antes mencionado, se seleccionaron 23 investigaciones extraídas de bases de datos internacionales, haciendo uso de criterios de búsqueda como convolutional neural networks, pneumonia, coronavirus, pulmonary, lungs, chest disease, covid-19 y lung disease. Los resultados obtenidos muestran distintas estrategias del uso de las redes neuronales convolucionales en la detección de afecciones respiratorias, las cuales pueden ser agrupadas en dos categorías: detección de afecciones respiratorias en tomografías de tórax y detección de afecciones respiratorias en radiografías de tórax. De acuerdo con lo mencionado, se concluye que el empleo de las redes neuronales convolucionales es relevante, debido a la gran cantidad de resultados favorables que se han dado a lo largo del tiempo en el campo de la imagenología

Restoration prioritization framework for roadway high cut slopes to reverse land degradation and fragmentation

[EN] Land degradation is one of the most critical global environmental threats. The EU Biodiversity Strategy to 2020 has appointed land degradation and ecosystems fragmentation caused by transport infrastructures as crucial threats to biodiversity. Implementing environmental criteria in roadway project conception phase for restoring large cut slopes will prevent this threat. There is a lack of decision support systems to implement environmental criteria in the decision making procedure to restore high cut slopes. The major difficulties have been building consensus and ensuring traceability and transparency from the panel of experts. This paper presents a hybrid framework capable of dealing with environmental criteria and also with conventional territorial and economic criteria. The decision support procedure combines the Analytical Hierarchy Process with the Delphi technique and the VIKOR procedure. The experts' consensual decision-making process is properly documented, unambiguous and verifiable. The results of this study yielded that the functional and environmental criteria are the key factors in the decision-making process of large cut slope restoration projects. And it has been found the suitability of the cut-and-cover tunnels despite their higher cost and complexity of its construction.Canto-Perello, J.; Morera Escrich, JL.; Martín Utrillas, MG.; Curiel-Esparza, J.

Estimating soil organic carbon in agricultural gypsiferous soils by diffuse reflectance spectroscopy

Contents of soil organic carbon (SOC), gypsum, CaCO3, and quartz, among others, were analyzed and related to reflectance features in visible and near-infrared (VIS/NIR) range, using partial least square regression (PLSR) in ParLes software. Soil samples come from a sloping olive grove managed by frequent tillage in a gypsiferous area of Central Spain. Samples were collected in three different layers, at 0-10, 10-20 and 20-30 cm depth (IPCC guidelines for Greenhouse Gas Inventories Programme in 2006). Analyses were performed by C Loss-On-Ignition, X-ray diffraction and water content by the Richards plates method. Significant differences for SOC, gypsum, and CaCO3 were found between layers; similarly, soil reflectance for 30 cm depth layers was higher. The resulting PLSR models (60 samples for calibration and 30 independent samples for validation) yielded good predictions for SOC (R2 = 0.74), moderate prediction ability for gypsum and were not accurate for the rest of rest of soil components. Importantly, SOC content was related to water available capacity. Soils with high reflectance features held c.a. 40% less water than soils with less reflectance. Therefore, higher reflectance can be related to degradation in gypsiferous soil. The starting point of soil degradation and further evolution could be established and mapped through remote sensing techniques for policy decision makingThis research was funded by regional and national funding projects AGRISOST-CM (S2013/ABI-2717); FP12-CVO; ACCION Project, GO-LEÑOSOS

Characterization of nanostructured SnO2 films deposited by reactive DC-magnetron sputtering

Nanostructured tin oxide thin films were deposited on silicon and glass slides substrates by reactive DC-Magnetron sputtering using a tin target in a mixture of argon and oxygen gases. The substrate temperature was varied in the range from 53 to 243 oC, keeping the other deposition parameters constant. The tin oxide films were characterized by: Scanning Electron Microscopy, Energy Dispersive Spectrometry, X Ray Diffraction, microRaman spectroscopy and UV-VIS spectroscopy. It was found that the substrate temperature has an effect mainly on the structural, morphological and optical properties of the thin films. At 53 and 90 oC the tetragonal crystalline phase was obtained while a mixture of crystalline phases (o-SnO2 and t-SnO2) was obtained at 148, 185 and 243 oC

Microstructural Study of a Zn-Ni Alloy Prepared by Ball Milling Using Two Different Devices

Metallic zinc (Zn) has ben extensively used as protective coating of iron and steel for decades, but problems related with its high permeability has reduced its application. It was found that the corrosion resistance of zinc in form of alloys is increased by adding some transition metals. Recently, the Zn-Ni system is under research as an efficient alternative as anticorrosion coating for metals. Zn-Ni is mostly prepared by electroplating or thermal spray technologies, but there are some problems like: (i) fluctuation of Zn-Ni contents, (ii) the pollution caused by plating solutions and (iii) irregular thickness of the coating. The mechanical alloying (MA) technique can be used to fulfill the above issues because this route facilitates the synthesis of homogeneous materials from powder mixtures . Also, MA is frequently employed for the preparation of new materials based on mechanochemical reactions performed at room temperature, while avoiding the conventional ingot metallurgy [3]. This work deals with the preparation and study of a Zn-Ni alloy prepared by MA using two types of milling devices: a planetary which works manly through abrasion and impact of grinding balls and the Spex which works through the high-energy impact of balls. Zn-Ni was prepared from pure Ni and Zn powders, the equiatomic compositions were weighed and milled for 4 hours followed by sintering at 357°C during 1h
