Infra-Red thermal image analysis for grapevines

Trabajo presentado en el 18th International Symposium of the Group of International Experts of vitivinicultural Systems for CoOperation (GIESCO 2013), celebrado en Oporto del 7 al 11 de julio de 2013.-- Número fuera de serie.Infrared thermal images (IRTI) have been used for grapevine research since the early 90’s. Even though its promising results in the assessment of canopy stomatal conductance and plant water status, from the beginning and recent research publications, it has not been fully applied on a commercial scale yet. It is believed that the bottleneck for this technology is the lack of reliable automation tools for IRTI analysis. Accurate and reliable automation technique s will allow the use of this technique to assess the spatial variability of physiological processes within the canopy using infrared cameras mounted on moving vehicles, drones, octocopters or robots. Automated analysis systems are requirement of The Vineyard of The Future initiative, which is an international effort to establis h fully monitored vineyards in the most prominent viticultural and winemaking areas in the world. In this work, a semi-automated IRTI analyses performed using a code written in MATLAB® for estimate dry and wet references excluding non-leaf temperatures was compared with evaporimeter (EvapoSensor, Skye Instruments Ltd, Powys, UK) measurements used to provide dry and wet references from IRTIs. Results obtained from this research (grapevines cv. Tempranillo) showed good and statistically significant correlations between temperatur e references obtained from IRTI analysis and measured values. This work constitutes one additional step forward to the implementation of thermal imaging as an automated routine technique for physiological vineyard assess ment from proximal sensing and unmanned aerial vehicles (UAV) platforms.The research leading to this report was supported by the Spanish project “STRESSIMAGING HPRN-CT-2002-00254” and Chilean projects CONICYT (Nº 79090035) and Programa de Investigación sobre Adaptación de la Agricultura al Cambio Climático - PIEI (Universidad de Talca).Peer Reviewe

CAMINOS SOSTENIBLES PARA LA ENSEÑANZA DE LA LENGUA MATERNA EN LAS SERIES INICIALES

RESUMEN Las autoras sitúan esta investigación dentro de los presentes cambios educativos que involucran la práctica del maestro-pedagogo, en lo que concierne a la educación lingüística, a partir de los siguientes problemas: 1) ¿Cómo incorporan o incorporaron conceptos de enseñanza de lengua como conjunto de variedades los maestros de la 4ª serie del nivel primario? 2) ¿Cómo usarían ellos un léxico específico sobre el habla amapaense, para tratar la noción de lengua como conjunto de variedades, considerando el paradigma de sustentabilidad en la educación lingüística? Para dar solución a estos problemas se elaboró el siguiente objetivo general: - Analizar el discurso docente sobre la práctica de enseñanza de lengua, concerniente a variación lingüística, en la 4ª serie del nivel fundamental, a partir del uso de un léxico específico sobre el habla local, considerando el paradigma de sustentabilidad en la educación lingüística. Para alcanzar tal objetivo, se realizó una investigación exploratorio-analítica, de metodología cualitativa y de cuño interpretativo. La especificidad del objeto requiere, en este caso, que se utilice la contribución teórico-metodológica de la Sociolingüística Variacional (SV) y Sociolingüística Educacional (SE), y para la sustentabilidad en educación, el aporte de Hargreaves y de Fink, además de la Organización de las Naciones Unidas para Educación, Ciencia y Cultura (UNESCO), entre otros. Para el análisis de los discursos, se emplean recortes del PCNEF de lengua portuguesa de la escolaridad inicial y de los Proyectos Pedagógicos del Curso de Pedagogía de UNIFAP. Para la recolección de la información empírica, se optó por entrevistas semi-estructuradas y para la triangulación de datos, discursos documentales y el generado en trabajo de campo. Las hipótesis se resumen: i) las prácticas pedagógicas para el aprendizaje lingüístico favorecen las dimensiones profundidad, amplitud y duración de la sustentabilidad educativa; ii) a pesar de la existencia de obras específicas sobre el habla local, en la educación lingüística del Estado no existe preocupación por enseñar (ni reflexionar sobre la lengua materna), a partir de lo local para alcanzar lo universal/nacional, orientación sugerida por los PCNEF-LP (documentos oficiales).   PALABRAS CLAVE: Educación Lingüística Sustentable; Formación Docente; Práctica Pedagógica Docente; Léxico; Enseñanza   ABSTRACT The authors situate this research within the present educational changes that involve the practice of the teacher-pedagogue, as far as linguistic education is concerned, from the following problems: 1) How do 4th grade teachers of the elementary education incorporate concepts of language teaching as a set of varieties? 2) How would they use a specific lexicon about Amapaense’s discourse, to treat the notion of language as a set of varieties, considering the paradigm of sustainability in language education? In order to solve these problems, the following general objective was developed: -Analyze the teacher’s discourse about the practice of language instruction on linguistic variation at the 4th grade of the elementary education, based on the use of a specific lexicon of local discourse, considering the paradigm of sustainability in language teaching. To achieve this objective, an exploratory-analytical investigation was made, as well as a qualitative methodology of interpretative essence. The object’s specificity requires, in this case, the use of the theoretical-methodological contribution given by the Variance Sociolinguistics (VS), the Sociolinguistic Education (SE), and the sustainability in education, supported by Hargreaves and Fink, in addition to the United Nations Educational, Scientific and Cultural Organization (UNESCO), among others. For the speeches’ analysis, cutouts from the National Curricula Parameters for the Elementary Education and the Pedagogy Course Project from the Federal University of Amapá (UNIFAP) were used. For information collection, we opted for semi-structured interviews and data triangulation, documentary discourses and the generated material from the field work. Summarized hypotheses: i) pedagogical practices for language learning favor the depth, breadth and duration dimensions of educational sustainability; ii) despite the existence of specific works on the local discourse, within the State’s linguistic education there is not concern about teaching (or reflecting about the mother tongue), from local to universal/national, as suggested by the official documents.   KEYWORDS: Sustainable Linguistic Education; Teacher training; Teacher’s Pedagogical Practice; Lexicon; Teaching.     RESUMO Os autores situam essa pesquisa dentro das atuais mudanças educacionais que envolvem a prática do professor-pedagogo, no que se refere à educação linguística, a partir dos seguintes problemas: 1) Como incorporam ou incorporam conceitos de ensino de línguas como um todo? de variedades os professores da 4ª série do nível primário? 2) Como eles usariam um léxico específico sobre o discurso de Amapase, para tratar a noção de linguagem como um conjunto de variedades, considerando o paradigma da sustentabilidade na educação de línguas?

Biochemical and microbiological analysis of the saliva of institutionalized elderly : with edentulism, use of dentures and presence of biofilm

To analyze biochemical and microbiological parameters of the saliva of institutionalized elders and to investigate the relation of these parameters with edentulism, use of dentures and presence of biofilm. A cross-sectional study carried was out in seven long-term institutions. Samples (n=161) of unstimulated saliva were collected for analysis of salivary flow, quantification of total proteins and identification of microorganisms. Oral examination was carried out to verify the number of missing teeth, the use of dentures and the presence of visible biofilm on the surface of teeth and dentures. Associations were performed using chi-square or Fisher?s exact test (?0.05). Associations were observed between the presence of dentures biofilm and the colonization of Streptococcus sp. (p=0.038) and Candida sp. (p=0.03). The absence of teeth and use of dentures do not influence the amount of total proteins and the microorganisms count in saliva. Denture biofilms are associated with the presence of Streptococcus sp. and Candida sp. in saliva of institutionalized elders

Metabolic syndrome in elderly from a northeastern brazilian city

Introduction: Population aging is a global reality. In Brazil, it is so expressive and in 2050 is estimated that the number of men and women over 80 years old can overcome the 20-24 years old population and also children under 14 years old. Metabolic syndrome is defined as a set of cardiovascular risk factors, detection and intervention in this age group may decrease cardiovascular mortality. We aimed to estimate the prevalence of metabolic syndrome (MS) in elderly patients in a northeastern Brazilian city. Method: This is a quantitative, observational, cross-sectional and population-based study. The population consisted of non-institutionalized individuals aged> 60 years old, attended in the Family Health Strategy (FHS) and residents in Cajazeiras, PB, Brazil. For the diagnosis of metabolic syndrome we considered the criteria recommended by the International Federation of Diabetes. Results: We studied 351 elderly patients with 72.4+8.7 years old and 66.1% were female. The prevalence of MS was 69.8% and the most frequent criterion was increased waist circumference (82.6%), followed by high triglycerides (81.5%) and low HDL-cholesterol (80.6%). We observed a statistically significant positive association between MS and women [OR: 1.38 (95% CI: 1.18 to 1.63)] and housing in urban areas [OR: 1.23 (1.02 to 1.48)]. Conclusion: There is a high prevalence of MS among the elderly mainly in women and those living in urban areas

Co-infecção pelo vírus dengue 3 e 4 em pacientes da Amazônia brasileira

The natural co-infection with dengue virus can occur in highly endemic areas where different serotypes have been observed for many years. We report here four cases of DENV-3/DENV-4 co-infection detected by serological and molecular tests among 674 patients with acute undifferentiated fever from the tropical medicine reference center of Manaus City, Brazil, between 2005 and 2010. Analysis of the sequences obtained indicated the presence of genotype 3 and 1 for DENV-3 and DENV-4 respectively.A co-infecção natural com os vírus dengue pode ocorre em áreas altamente endêmicas onde diferentes sorotipos têm sido transmitidos por muitos anos.

Se las presenta y se analiza su efectividad en función de los resultados obtenidos hasta el momento, acompañando el proceso con estudios arqueométricos. Se incluye el diagnóstico del estado de conservación basado en información actual y documentación histórica, así como la descripción del carácter distintivo desde el punto de vista iconográfico de algunas representaciones, que ponen de relieve la materialidad sobre la que trabajamos

AVALIAÇÃO MICROBIOLÓGICA E FÍSICO-QUÍMICA DE DOCE DE LEITE E REQUEIJÃO PRODUZIDOS COM LEITE DE BUFÁLA NA ILHA DO MARAJÓ- PA

Avaliou-se a qualidade microbiológica e físico-química de doces de leite e requeijões produzidos, na Ilha do Marajó PA (Brasil), com leite de búfala. Não foi detectada a presença de Salmonellas e Staph ylococcus aureus nas amostras dos produtos analisados e os resultados obtidos para contagem de bactérias mesófilas e bolores e leveduras para o doce de leite demonstraram boas condições higiênicosanitárias do produto. Porém, 28,60% das amostras de requeijão apresentaram condições higiênico-sanitárias insatisfatórias, sendo 14,26% consideradas impróprias para o consumo humano. Na caracterização físico-química, 83,34% das amostras de doce de leite apresentaram teores de gordura superiores ao padrão (6,0 a 9,0%) e uma amostra mostrou-se acima do limite permitido (máx. 30%) para umidade. Verificou-se que 100% das amostras de requeijão apresentaram teores de proteínas (mín. 5%) e umidade (máx. 60%) de acordo com os padrões e apenas 14,86% enquadraram-se no padrão para gordura no extrato seco total (45 a 54,9%). Esses resultados sugerem que o requeijão de leite de búfala pode estar sendo produzido a partir de matérias-primas de qualidade microbiológica inadequada ou o produto está sendo contaminado durante a produção, o transporte, o armazenamento ou a comercialização. MICROBIOLOGICAL AND PHYSICAL-CHEMISTRY EVALUATION OF SWEETENED MILK AND SPREAD CHEESE PRODUCED WITH BUFALLO´S MILK IN MARAJO ISLAND - PA Abstract The microbiological and physical-chemistry quality of the Sweetened milk and the Spread cheese produced with Buffalo´s milk, in Marajó Island - PA, were evaluated. It was not detected the presence of Salmonella and Staphylococcus aureus in samples of the analysed products and the results obtained for mesophilic bacteria, molds and yeast counting for sweetened milk showed good sanitary conditions of the product. However, 28,60% of the Spread cheese samples presented insatisfactories conditions and 14,26% were inappropriate for human consumption. At the physical-chemistry characterization, 83,34% of the Sweetened milk samples presented contents of fat superior to the pattern (6,0 a 9,0), and about the humidity, just a sample was above the pattern (max.30%). For the Spread cheese, it was verified that 100% of the samples presented contents of proteins (min.5%) and humidity (max.60%) inside the pattern and only 14,86% were inside of the pattern for fat in total solids (45% to 54,9%). It may be inferred that Spread cheese produced with Buffalo´s milk has been either with milk of inadequate sanitary conditions or contaminated during the process, transportation, storage and commercialization
