Internet photosharing websites is a very recent and powerful tool for the study of biodiversity, and a meeting point of general public fond of nature and professional naturalists. The article discusses when an uploaded picture is scientifically valuable, and the benefits of structured hosting websites for the most fruitful information retrieval. Examples are given of faunistic, biological, ecological and conservation results concerning Hemiptera provided by information download from photosharing websites.

El objetivo de este trabajo de investigación es comprender el comportamiento de flujo del agua a través de la contracción gradual. La dinámica de fluidos computacional (CFD), es un enfoque útil para resolver las ecuaciones que describen el movimiento de los fluidos, mediante métodos numéricos y técnicas computacionales. Esta área de la mecánica, proporciona los fundamentos de la hidráulica de tuberías e hidráulica de canales. Se ha realizado un estudio del flujo a través de la tubería para calcular las pérdidas en los cambios de la geometría. Las pérdidas de energía debido al cambio transversal del área, es una parte importante para analizar el flujo a través de las tuberías. Se calculo que las pérdidas ocurren debido a cambios en la geometría por parte del experimento y también con la ayuda del software ANSYS fluent. Se emplearon cálculos usando el modelo K-épsilon. Esta simulación proporciona los valores de los contornos de presión, velocidad y turbulencia cinética en varias secciones de la tubería donde el agua es su flujo.

Background: In Ecuador, the neonatal mortality rate has increased from 4.1 to 6.0 per 1000 live births between 2014 and 2019. We aimed to develop and validate a health risk assessment tool for predicting neonatal mortality and to reach a nationwide consensus on stratified management. Methods: We retrospectively analyzed all neonatal deaths registered by the Ministry of Public Health between 2014 and 2017 in Ecuador. We developed a health risk assessment tool by using the information of deceased neonates between 2014 and 2016, and subsequently validated it using the information of deceased neonates in 2017. Several perinatal predictors were tested. The score was qualitatively refined by ~70 healthcare professionals in five Ecuadorian cities, and it was transformed into a web-based calculator with stratified suggestions of care. Results: Survival estimates differed significantly across the risk bands. The resulting Score Bebé® is available at https://scorebebe.com/ and includes stratified suggestions for care.
