Performance of passive application of PCM in Spain

Contemporary construction systems tend to be thinner, lighter and better insulated than ever, but usually lack thermal mass. In order to improve the indoor temperature and reduce the energy consumption in the lightweight building it is necessary to add thermal energy storage capacity to the construction elements. Phase change materials (PCM) have high a heat of fusion so they can absorb a lot of thermal energy before melting or solidifying without adding physical mass. The stored energy can be released later when it is necessary. The main purpose of this study is to quantify the effectiveness of PCMs as interior temperature stabilizers in the Spanish construction. Another goal was to identify the influence of the windows sizes and their shading factor in a PCM´s passive application, and find out the most convenient combinations. A comparative study has been made, simulating a Test Room, with and without PCM, to predict the annual interior temperature behavior in each case. The thermal performance of the test rooms was evaluated on an hour to hour basis, in several Spanish climate zones with diverse combinations of facade glazing ratio and window shadow factors (Fs). The results indicate that the addition of PCM to building partitions help to maintain the interior thermal comfort, reducing the high and low temperature peaks in all Spanish climates studied. The PCM thermal stabilizing capacity is more noticeable in summer. However, the Test Room in the warmer climate falls behind in the overall results. The PCM passive application has demonstrated to help to maintain a uniform interior temperature and to save energy, but its use is not a cost effective solution for all the cases in the study. This study helps to identify when, and where, the use of this PCM application should be more appropriate

Efecto de un programa de intervención en los procesos y estrategias para la comprensión lectora en estudiantes de 5º y 6º grado

Background: Various investigations have revealed that the promotion of cognitive and metacognitive strategies can improve reading comprehension and that when readers receive this type of instruction, they can use monitoring processes and regulation strategies adequately. The goal of this work is to analyze the effects of strategic and metacognitive instruction on reading comprehension processes and strategies, using the "Aprender a Comprender" [Learning to Understand] program. Method: Instruction was carried out in the classroom by two teachers during six months. Ninety-four students participated, 49 from 5th grade and 45 from 6th grade. A pretest-intervention-posttest-follow-up design was used with a comparison group by grade. Results: The analysis of variance shows an impact of the intervention and its differential maintenance in each grade. The 5th-grade intervention group scored higher than the comparison group in the reading comprehension test, both at posttest and at follow-up. The 6th-grade intervention group scored higher than the comparison group in the Planning scale, both at posttest and at follow-up. Conclusions: Textual strategy instruction favors reading comprehension and the progressive development of planning, which is necessary for supervision and regulation, and its effects are maintained over time.Antecedentes: diferentes investigaciones han evidenciado que el fomento de estrategias cognitivas y metacognitivas puede mejorar la comprensión lectora y su instrucción favorece la utilización adecuada de los procesos de monitoreo y de las estrategias de regulación.

Methodology in research on photovoltaic cogeneration integrated in building

There are currently various universities and institutions developing research into the integration of photovoltaic systems in buildings, internationally known by its abbreviation in English, BIPV (Building Integrated Photovoltaics). Within this technology, one aspect stands out, considered innovative, the integration of hybrid models or cogeneration. This technology, which we shall call BIPVT (Building Integrated Photovoltaics Thermal), integrates a hybrid module in the building, which not only generates electricity, but also uses residual energy that is lost in the form of heat or light, to increase the energy efficiency of the building, in applications with low temperature. However, the methods to test the efficiency of this investigation and evaluate its cost benefit, are not clear, and constitute a challenge for the investigation within an architectural framework

Epidemiological And Genetic Characteristics Associated With The Severity Of Acute Viral Bronchiolitis By Respiratory Syncytial Virus.

to assess the epidemiological and genetic factors associated with severity of acute viral bronchiolitis (AVB) by respiratory syncytial virus (RSV). the key words bronchiolitis, risk factor, genetics and respiratory syncytial virus, and all combinations among them were used to perform a search in the PubMed, SciELO, and Lilacs databases, of articles published after the year 2000 that included individuals younger than 2 years of age. a total of 1,259 articles were found, and their respective summaries were read. Of these, 81 were selected, which assessed risk factors for the severity of AVB, and were read in full; the 60 most relevant studies were included. The epidemiologic factors associated with AVB severity by RSV were prematurity, passive smoking, young age, lack of breastfeeding, chronic lung disease, congenital heart disease, male gender, ethnicity, viral coinfection, low weight at admission, maternal smoking during pregnancy, atopic dermatitis, mechanical ventilation in the neonatal period, maternal history of atopy and/or asthma during pregnancy, season of birth, low socioeconomic status, Down syndrome, environmental pollution, living at an altitude > 2,500 meters above sea level, and cesarean section birth. Conversely, some children with severe AVB did not present any of these risk factors. In this regard, recent studies have verified the influence of genetic factors on the severity of AVB by RSV. Polymorphisms of the TLRs, RANTES, JUN, IFNA5, NOS2, CX3CR1, ILs, and VDR genes have been shown to be associated with more severe evolution of AVB by RSV. the severity of AVB by RSV is a phenomenon that depends on the varying degrees of interaction among epidemiological, environmental, and genetic variables.89531-4

Symbolic AI for XAI: Evaluating LFIT inductive programming for explaining biases in machine learning

Machine learning methods are growing in relevance for biometrics and personal information processing in domains such as forensics, e-health, recruitment, and e-learning. In these domains, white-box (human-readable) explanations of systems built on machine learning methods become crucial. Inductive logic programming (ILP) is a subfield of symbolic AI aimed to automatically learn declarative theories about the processing of data. Learning from interpretation transition (LFIT) is an ILP technique that can learn a propositional logic theory equivalent to a given black-box system (under certain conditions). The present work takes a first step to a general methodology to incorporate accurate declarative explanations to classic machine learning by checking the viability of LFIT in a specific AI application scenario: fair recruitment based on an automatic tool generated with machine learning methods for ranking Curricula Vitae that incorporates soft biometric information (gender and ethnicity). We show the expressiveness of LFIT for this specific problem and propose a scheme that can be applicable to other domains. In order to check the ability to cope with other domains no matter the machine learning paradigm used, we have done a preliminary test of the expressiveness of LFIT, feeding it with a real dataset about adult incomes taken from the US census, in which we consider the income level as a function of the rest of attributes to verify if LFIT can provide logical theory to support and explain to what extent higher incomes are biased by gender and ethnicityThis work was supported by projects: PRIMA (H2020-MSCA-ITN-2019-860315), TRESPASS-ETN(H2020-MSCA-ITN-2019-860813), IDEA-FAST (IMI2-2018-15-853981), BIBECA(RTI2018-101248-B-I00MINECO/FEDER), RTI2018-095232-B-C22MINECO, PLeNTaS project PID2019-111430RBI00MINECO; and also by Pays de la Loire Region through RFI Atlanstic 202

Cystic fibrosis at a Brazilian center of excellence: clinical and laboratory characteristics of 104 patients and their association with genotype and disease severity

OBJECTIVE: To identify the clinical, laboratory and radiographic characteristics of the cystic fibrosis patients under care at Universidade Estadual de Campinas (UNICAMP) in the last decade of the twentieth century, and to investigate the association of these characteristics with genotype and severity of the disease as measured by the Shwachman score. METHODS: Descriptive, retrospective and cross-sectional study of the patients assisted at UNICAMP hospital's Cystic Fibrosis Clinic from July 1990 to July 2000. RESULTS: One hundred and four patients were studied; 53.8% male; 93.3% Caucasian; 89.4% presented with respiratory symptoms; 59.6% presented with digestive symptoms; 5.8% had meconium ileus ; 4.8% had diabetes. The mean age at onset of symptoms was 3 months, and the mean age at diagnosis was 2 years and 4 months. At diagnosis, 69.9 and 56.6% of the patients had weight and height below 10th percentile, respectively; in 10.6%, sweat chloride was < 60 mEq/l. Staphylococcus aureus was found in 80.2%, Pseudomonas aeruginosa in 76.0%, and Burkholderia cepacia in 5.2%. deltaF508 homozygosis was observed in 18.75%, whereas 62.50% of the patients were deltaF508 heterozygous. A moderate/severe Shwachman score was found in 15.7%. Eighteen patients died in that period (17.3%). The mean age at death was 7 years and 8 months; median survival after diagnosis was 18 years and 4 months. Patients who have at least one deltaF508 mutation have more frequent alterations in fecal fat levels when compared to patients who do not have this mutation (p < 0.05). There were no differences in any parameter between deltaF508 homozygous and heterozygous patients. CONCLUSIONS: The clinical and laboratory characteristics of the 104 patients studied were similar to the characteristics described for patients in other countries. Exceptions are the higher age at diagnosis and lower survival. Our results support the recommendation for early diagnosis and the need for more treatment opportunities in the population of cystic fibrosis patients.OBJETIVO: Estudar as características clínicas, laboratoriais e radiográficas de pacientes fibrocísticos acompanhados na última década do século 20 na UNICAMP e verificar se existe associação com o genótipo e a gravidade da doença medida pelo escore de Shwachman. MÉTODOS: Estudo descritivo, retrospectivo e de corte transversal dos pacientes fibrocísticos acompanhados na UNICAMP, que tiveram atendimento entre julho de 1990 e julho de 2000. RESULTADOS: Foram estudados 104 pacientes: sexo masculino - 53,8%; raça caucasóide - 93,3%; comprometimento pulmonar - 89,4%, comprometimento digestivo - 59,6%; íleo meconial - 5,8%; diabetes melito - 4,8%; mediana da idade de início dos sintomas - 3 meses; mediana da idade no diagnóstico - 2 anos e 4 meses; 69,9 e 56,6% apresentavam peso e estatura abaixo do percentil 10, respectivamente, na época do diagnóstico; dosagem de cloro no suor < 60 mEq/l - 10,6%; colonização: S. aureus - 80,2%, P. aeruginosa - 76,0%, B. cepacia - 5,2%; delta F508 homozigoto - 18,75%, deltaF508 heterozigoto - 62,5%; escore de Shwachman moderado/grave - 15,7%. Foram a óbito 18 pacientes (17,3%); mediana de idade do óbito de 7 anos e 8 meses; sobrevida mediana após o diagnóstico no término do estudo de 18 anos e 4 meses. Os pacientes com a mutação deltaF508 apresentaram balanço de gordura nas fezes alterado com maior freqüência que os pacientes sem essa mutação (p < 0,05). Quando comparados os pacientes que apresentavam uma ou duas mutações deltaF508, nenhum parâmetro apresentou diferença estatisticamente significativa. CONCLUSÕES: As características clínicas e laboratoriais dos pacientes estudados foram semelhantes às descritas na população fibrocística de outros países, com algumas exceções, dentre as quais destacamos maior idade no diagnóstico e menor sobrevida. Desta forma, nossos dados permitem inferir que esforços para um diagnóstico precoce e maior oportunidade de tratamento necessitam ser dirigidos aos pacientes fibrocísticos.37137
