Principais aspectos da biologia da mosca do sorgo, Contarinia sorghicola (Coquillett, 1898) (Diptera: Cecidomyiidae).

O mosca do sorgo, Contarinia sorghicola (Coquillet, 1898) (Diptera: Cecidomyiidae) constitui um dos serios problemas para o cultivo do sorgo no Brasil. A sua biologia foi estudada no Sorghum bicolor (L.) Moench em ambiente de laboratorio, para as condicoes de Sete Lagoas, MG, sendo repetida em 5 epocas com intervalo de 20 dias. Observou-se o florescimento das paniculas e o controle de oviposicao de mosca. As plantas foram levadas para o laboratorio e mantidas em provetas com agua. Suas espiguetas foram examinadas diariamente para identificacao das fases do inseto. O periodo medio de incubacao foi de 3,00 +/- 0,00 dias, o larval de 8,20 +/- 0,08 dias e o pupal de 3,77 +/- 0,09 dias. A menor mortalidade deu-se na fase de ovo e a maior na fase de larva

Propuestas de trabajo innovadoras y colaborativas e-learning 2.0 como demanda de la sociedad del conocimiento

La evolución del tradicional concepto de e-learning está presente, en gran medida, gracias a la introducción de herramientas web 2.0 en los procesos de enseñanza-aprendizaje en la Universidad. Una evolución (e-learning 2.0) que advierte de la promoción de un alumno o alumna comprometido con su aprendizaje, que construye significativamente, que potencia el trabajo en red y que subraya capacidad ante los procesos innovadores mediante el cambio de actitud necesario. El proyecto Redes Interuniversitarias no es más que la verificación y proyección de dichos principios en el intento de la mejora de la calidad

Distribuição radicular da bananeira `prata-anã´ sob diferentes regimes de irrigação no primeiro ciclo.

Objetivou-se com este trabalho avaliar a distribuição do sistema radicular da bananeira ?Prata-Anã? sob diferentes regimes de irrigação no semiárido baiano. A análise seguiu um esquema fatorial 5 x 5 x 4, cinco estratégias de irrigação, cinco distâncias do pseudocaule e quatro profundidades com três repetições em blocos casualizados. As estratégias de irrigação foram: (L1: 0,20; L2: 0,35; L3: 0,50 e L4: 0,65) x AF (área foliar) x (ETo) e L5: conforme a ETc utilizando sistema de irrigação por gotejamento no primeiro ciclo produtivo. As distâncias amostradas no sentido longitudinal e perpendicular à fileira de plantas foram: 0,15, 0,40, 0,65, 0,90 e 1,20 m do pseudocaule, e profundidades de: 0 ? 0,20, 0,20 ? 0,40, 0,40 ? 0,60 e 0,60 ? 0,80 m. O espaçamento de plantio é de 3,0 x 2,5 mem um Latossolo de textura média. As diferentes estratégias de irrigação não alteraram a distribuição do sistema radicular de bananeira ?Prata-Anã?. Não foram observadas diferenças entre o sistema radicular da ?Prata-Anã? no sentido longitudinal e no perpendicular às linhas de irrigação.A maior concentração de raízes ocorreu até a distância de aproximadamente 0,50 m do pseudocaule e a uma profundidade do solo próxima a 0,40 m

Health economics: identifying leading producers, countries relative specialization and themes

El área de investigación en economía de la salud tuvo una gran evolución a partir de la década de 1960 y está en constante crecimiento. Actualmente, el gasto en salud es un tema clave en todo el mundo. La bibliometría proporciona varios métodos para explorar el impacto y la evolución de la investigación. Así pues, el principal objetivo del presente estudio es comprender la situación actual de la investigación en materia de economía de la salud para el período 2010-2019. Se analizaron tres aspectos diferentes: la producción de los países, el índice de prioridad relativa y los temas principales. El conjunto de datos se obtuvo a partir de los documentos indizados en la base de datos Web of Science de 2010 a 2019. Se utilizó el software SciMAT para obtener el análisis temático mediante el análisis de mapas de la ciencia. Las revistas Health economics, Value in Health, Journal of Health Economics y European Journal of Health Economics son los principales productoras. Estados Unidos, Inglaterra y Alemania son los que tienen una mayor producción; los Países Bajos, Inglaterra y Australia son los que tienen el índice de prioridad relativa más alto. Los años de vida ajustados en función de la calidad y la desigualdad en materia de salud son los temas con mayor número de documentos y medidas de impacto. Este estudio es un marco útil basado en ciencia que servirá de base para futuras acciones de investigación.Health economics research area was a high evolution from the 1960s and it is constantly growing.

USA, England and Germany are those with highest production; Netherlands, England and Australia are those with the highest relative priority index. Quality adjusted life years and Health inequality are the themes with the highest number of documents and impact measures. This study is a useful evidence-based framework on which to base future research actions

Renewable medium-small projects in Spain: Past and present of microgrid development

This paper reviews the on-going research studies and microgrid pilot projects focusing on the Spanish case because of its renewable energy potential with the objective set on highlights the main investigation drifts in the field such as the used technologies, control methods and operation challenges. That way, several smart grids have been commented and compared, finding that photovoltaic and wind power are the favourites energy generation technologies. Although batteries are the most widespread energy storage systems, green hydrogen has a strong presence, showing up in a third of the Spanish smart grids. Traditional control strategies are being displaced by advanced ones such as MPC or fuzzy logic due to its higher efficiency. The reader will have a clear view of the potential of renewable energy penetration in the form of smart grids in Spain, through the study of the equipment involved in the different facilities contribution and the main control strategies implemented, in a comparative analysis of the key aspect of this emerging technology.Consejería de Conocimiento, Investigación y Universidad - Junta de Andalucía PY18-RE-002

Bacteriophages in bathing wàters: A feasibility study on the development of a method based on bacteriophages for the determination of microbiological quality of bathing waters

Projecte: Project report. BCR Information. EU project KINA19506ENC_001. EUROPEAN COMMISSION. Community Research. DG XII/C - Competitive and Sustainable Growth Programme. Published by EU Directorate General ΧΠ - Science, Research and Development ISBN 92-828-9145-3Informe final projecte europeu aigües de bany i bacteriòfagsMethods for the detection and enumeration of somatic coliphages, F-specific RNA bacteriophages and bacteriophages infecting Bacteroides fragilis had been standardised and validated. Conditions for the preparation, transport and distribution of bacteriophage reference materials and preservation of samples had been defined. A method based on flocculation with Mg(OH2) with concentration efficiencies from about 40% was settled to concentrate phages from bathing waters. All methods were successfully implemented in routine laboratories all around the EU. Data on the occurrence of bacteriophages as compared to E. coli and Enterococci are available from diverse situations encountered in the EU. Results allow to conclude that the potential of phages for the determination of the microbiological quality of bathing waters merits to be considered since their determination is feasible and their behaviour in natural water differs from the behaviour of bacterial indicators and consequently they add valuable information
