Refrigeration Capacity and Effect of Ageing on the Operation of Cellulose Evaporative Cooling Pads, by Wind Tunnel Analysis

This study investigates the temperature reduction capacity and water consumption of a fan-pad system installed in a greenhouse located in the coastal regions of Almería. The suitability of this system for coastal zones with high environmental humidity during the summer is analyzed. Historical temperature and relative humidity series are studied, obtaining the thermal difference and maximum, medium, and minimum monthly water consumption of the pads based on the operation data of the pads. Despite the high relative humidity of the air in the hottest hours of the day, a decrease of 5.92 ºC in the mean temperature and a water consumption of 13.55 l/h per square meter of an evaporative cooling pad are obtained in the month of August. Additionally, the operation of a cellulose evaporative cooling pad installed for 3 years in a greenhouse is analyzed in a wind tunnel and compared with that of a new pad of the same model. Over time and with low maintenance, the porosity of the pad decreases due to salt incrustation. The salt incrustation makes airflow more difficult in the pad, increasing the pressure drop by 170.04%; however, the air saturation efficiency of the pad increases by 6.6% due to the greater contact time between the air and the waterMinisterio de Economía y Competitividad de España AGL2015-68050-RUnión Europea (FEDER) AGL2015-68050-

Energy Efficiency in Greenhouse Evaporative Cooling Techniques: Cooling Boxes versus Cellulose Pads

Evaporative cooling systems using a combination of evaporative pads and extractor fans require greenhouses to be hermetic. The greatest concentration of greenhouses in the world is located in southeast Spain, but these tend not to be hermetic structures and consequently can only rely on fogging systems as evaporative cooling techniques. Evaporative cooling boxes provide an alternative to such systems. Using a low-speed wind tunnel, the present work has compared the performance of this system with four pads of differing geometry and thickness manufactured by two different companies. The results obtained show that the plastic packing in the cooling unit produces a pressure drop of 11.05 Pa at 2 m·s−1, which is between 51.27% and 94.87% lower than that produced by the cellulose pads. This pressure drop was not influenced by increases in the water flow. The evaporative cooling boxes presented greater saturation efficiency at the same flow, namely 82.63%, as opposed to an average figure of 65% for the cellulose pads; and also had a lower specific consumption of water, at around 3.05 L·h−1·m−2·°C−1. Consequently, we conclude that evaporative cooling boxes are a good option for cooling non-hermetic greenhouses such as those most frequently used in the Mediterranean basin

Stabilization method in two-body systems with core excitations

The validity of the stabilization method in core+valence systems including the possibility of exciting the core is studied. A pseudostate method, based on the transformed harmonic oscillator basis, is extended to include the core degrees of freedom. The method is applied to the case of 11Be structure considering the 0+ ground state and the 2+ first excited state of the 10Be core. The stabilization method is defined in terms of one parameter that can be chosen either discrete or continuous. In the application to 11Be, both cases are analyzed.Ministerio de Ciencia e Innovación FIS2011-28738-c02-01, FPA2009-07653, FPA2009-08848, CSD2007-00042Junta de Andalucía FQM160, P07-FQM-0289

Core excitation effects in halo nuclei using a transformed oscillator basis

A recent generalization of the Transformed Harmonic Oscillator basis, intended to consider core excitations in the structure of one nucleon halo nuclei, is applied to the break up of 11Be. The reaction studied is 11Be+208Pb at 69 MeV/nucleon. The experimental set up is designed to ensure pure dipole Coulomb excitations. Making use of the Equivalent Photon Method and the electromagnetic transition probabilities obtained with the transformed oscillator basis, a relevant contribution of the quadrupole excitations of the core is found. The inclusion of core excitations is, therefore, necessary for the correct extraction of the dipole electromagnetic transition probability of halo nuclei.Ministerio de Ciencia e Innovación FIS2011-28738-c02-01, FPA2009- 07653, FPA2009-08848, CSD2007-00042Junta de Andalucía FQM160, P07-FQM-0289

Automatic Bayesian Density Analysis

Making sense of a dataset in an automatic and unsupervised fashion is a challenging problem in statistics and AI. Classical approaches for {exploratory data analysis} are usually not flexible enough to deal with the uncertainty inherent to real-world data: they are often restricted to fixed latent interaction models and homogeneous likelihoods; they are sensitive to missing, corrupt and anomalous data; moreover, their expressiveness generally comes at the price of intractable inference. As a result, supervision from statisticians is usually needed to find the right model for the data. However, since domain experts are not necessarily also experts in statistics, we propose Automatic Bayesian Density Analysis (ABDA) to make exploratory data analysis accessible at large. Specifically, ABDA allows for automatic and efficient missing value estimation, statistical data type and likelihood discovery, anomaly detection and dependency structure mining, on top of providing accurate density estimation. Extensive empirical evidence shows that ABDA is a suitable tool for automatic exploratory analysis of mixed continuous and discrete tabular data.Comment: In proceedings of the Thirty-Third AAAI Conference on Artificial Intelligence (AAAI-19

Genetic conservation index in the Carthusian strain of the andalusian horses

In this work we have analysed the evolution of the effective number of the population base or founding of the Carthusian strain of the Spanish Pure Breed Horse (P.R.E.). The Stud Book has supplied the necessary information to constitute the data base formed with the set of Carthusian horses (2673 animals registered up to 1991). Concerning the base or founding population of the Carthusian strain, being 220 the number of animals that integrates the foundational group. At present and due to the selection policy of the individuals more significants, as well as to the type of line inbreeding employed within a strain with a low effective number of reproducers, only exist effective genetic representation of 22 antecedent (11 sires and 11 mares). The mean Genetic Conservation Index, seems have arrived to a stabilisation phase after a gradual increasing throughout the successive generations analysed. The interval 1980-1990 is emphasised, then takes a value of 14.23 the one which can be considered a good conservation level of those genetic lines that they were constituted by the group of founding ancestors.En este trabajo se ha analizado la evolución del número efectivo de la población base o fundadora de la estirpe Cartujana del caballo de P.R.E. El Libro Genealógico de la raza ha suministrado la información necesaria para constituir la base de datos formada por los 2.673 caballos Cartujanos inscritos hasta el año 1991. En cuanto a la población base o fundadora de la estirpe Cartujana, está constituida por aquellos antecesores que cierran los pedigríes de los animales que forman la estirpe. Según nuestros resultados es de 220 el número de animales que integra el grupo fundacional. En la actualidad y debido a la política de utilización exhaustiva de los individuos más emblemáticos y al tipo de endocría en línea empleada dentro de una estirpe con un bajo número efectivo de reproductores, sólo existe representación genética efectiva de 22 antecesores (11 sementales y 11 yeguas). El Índice de Conservación Genético medio parece haber llegado a una fase de estabilización después de un paulatino incremento a lo largo de los sucesivos periodos generacionales, siendo en el último intervalo analizado (1980-1990) de 14,23

Influence of the Carthusian strain in the andalusian horses

In this work the evolution of the Carthusian influence has been analysed in 33.486 Andalusian horses (P.R.E.) registered in the Stud Book from its opening in the year 1912 until 1990. It has been able to verify that the maximum number of the Carthusian predecessors, in a given generation level is reflected, in the form of greater percentage of influence, in three subsequent generations. The level of Carthusian influence in the set of the P.R.E. horses population has been increased in the successive generation intervals, being produced the four increases more meaningful in successive decades, from the years 30 until the years 70, with a total increase of the 55.28 percent of influence. In summary, more than 70 percent of the P.R.E. reproducers posses some Carthusian forefather between their registered antecedent in the Stud Book, being included in the level of the 80-100 percent of Carthusian blood the greater group of P.R.E. reproducers.En este trabajo se ha analizado la evolución de la influencia Cartujana en los 33.486 caballos de P.R.E. inscritos en el Stud Book hasta el año 1990. Se ha podido constatar que el máximo número de antecesores Cartujanos en un determinado nivel generacional se refleja, en forma de mayor porcentaje de influencia, en tres generaciones posteriores. El nivel de influencia Cartujana en el conjunto de la población de caballos de P.R.E. se ha visto incrementada en los sucesivos intervalos generacionales, produciéndose los cuatro incrementos más significativos en décadas sucesivas, desde los años 30 hasta los años 70, con un incremento total del 55,28 p.100 de influencia. En suma, más del 70 p.100 de la población de reproductores del P.R.E., posee algún antepasado Cartujano entre sus antecesores inscritos en el Libro genealógico, incluyéndose en el nivel del 80-100 p.100 de sangre Cartujana el mayor grupo de animales reproductores de la población del P.R.E

Laboratorio de Referencia Regional de Salud Pública de San Martín

Un Laboratorio de Referencia Regional de Salud Pública es el responsable de realizar acciones de diagnóstico, control de calidad, investigaciones y vigilancia epidemiológica dentro de la región San Martín a fin de contribuir con el control y vigilancia de la salud pública en la región. Su infraestructura debe considerar requerimientos de alta calidad, siguiendo los criterios establecidos por las normativas nacionales e internacionales vinculadas a la calidad de laboratorios, y considerando el equipamiento y las condiciones ambientales óptimas para el desarrollo de sus acciones dentro de cada uno de los ambientes de laboratorio, garantizando la calidad de sus procedimientos y el control biológico. En la actualidad, en el Perú, gran parte de los laboratorios que desempeñan funciones de vigilancia en el sector público no se encuentran en correctas condiciones para realizar las funciones que les corresponden ya que no cuentan con la infraestructura apropiada, lo cual pone en riesgo la eficacia de sus procedimientos de diagnóstico, control de calidad, investigaciones y vigilancia epidemiológica. Si bien existen laboratorios con óptimas condiciones de infraestructura y equipamiento adecuado, éstos se encuentran en el sector privado, lo cual genera que la población demandante tenga que pagar altos costos para obtener los servicios de diagnóstico, control de calidad y otros. El planteamiento arquitectónico permite el correcto desarrollo de las funciones de diagnóstico, control de calidad, investigaciones y vigilancia epidemiológica, en favor de la salud pública, a través de zonas de laboratorios óptimamente diseñados mediante una organización unidireccional, en donde todos los procedimientos se podrán realizar de manera eficaz y cumpliendo con los requerimientos establecidos en las normativas nacionales e internacionales. El proyecto desarrolla el diseño arquitectónico y las especialidades de ingeniería de la solución técnica del Laboratorio de Referencia Regional de Salud Pública de San Martín, haciendo énfasis en el desarrollo a detalle de las infraestructuras de los bloques del Laboratorio de Enfermedades Infecciosas y Laboratorio de Control de Calidad de Alimentos y Aguas.A Regional Public Health Reference Laboratory is in charge of carrying out diagnostic actions, quality control, investigations, and epidemiological surveillance within the San Martín region in order to contribute to the control and surveillance of public health in the region. Its infrastructure must consider high quality requirements, following the criteria established by national and international regulations related to the quality of laboratories, and considering the equipment and appropriate environmental conditions for the development of its activities within each of the laboratory environments, guaranteeing the quality of its procedures and biological control. At present, in Peru, a large part of the laboratories that carry out surveillance functions in the public sector are not in good conditions to carry out the functions that correspond to them since they do not have the appropriate infrastructure, which puts the quality of its diagnostic procedures, quality control, investigations and epidemiological surveillance at risk. Although there are laboratories with optimal infrastructure conditions and adequate equipment, they are in the private sector, which means that the demanding population has to pay high costs to obtain diagnostic, quality control and other services. The architectural plan allows the correct development of the functions of diagnosis, quality control, investigations and epidemiological surveillance, for the benefit of the public health of the population, through blocks of laboratories correctly designed through a unidirectional organization, where all the procedures can be carried out efficiently and complying with the quality requirements of national and international regulations. The project develops the design of the architecture and specialties of the general plan of the San Martín Regional Public Health Reference Laboratory, emphasizing the detailed development of the infrastructures of the blocks of the Infectious Diseases Laboratory and Quality Control Laboratory of Food and Water.Tesi

Non-destructive characterization of archeological Cu-based artifacts from the early metallurgy of southern Portugal

In this study, Monte Carlo (MC) simulations combined with energy dispersive X-ray fluorescence (EDXRF) spectroscopy have been used to characterize non-destructively a collection of Cu-based artifacts recovered from two archeological sites in southern Portugal: (a) the Chalcolithic E.T.A.R. site of Vila Nova de Mil Fontes and (b) the Middle Bronze Age site of Quinta do Estácio 6. The metal artifacts show a multilayered structure made up of three distinct layers: (a) brownish carbonate soil-derived crust, (b) green oxidized corrosion patina, and (c) bulk metal. In order to assess the reliability of the EDXRF-based Monte Carlo simulations to reproduce the composition of the alloy substrate in archeological bronze artifacts without the need to previously remove the superficial corrosion and soil derived patinas, EDXRF analysis together with scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS) was also performed on cleaned and patina-/crust-coated areas of the artifacts. Characterization of the mineralogical composition of the corrosion products in the surface patinas was further determined by means of X-ray diffraction (XRD). Results suggest that the adopted EDXRF/Monte Carlo protocol may represent a safe and fast analytical approach in the quantitative characterization of the bulk chemical composition of Cu-based metal artifacts even in the presence of fairly thick corrosion patinas and/or soil-derived encrustations at the surface of the archeological objects
