Potential of Jerusalem artichoke as an energetic crop: tuber yield and abovegro...

Jerusalem artichoke (Helianthus tuberosus) is a species of the Asteraceae family that has been grown for its edible tubers. It is also used as an ornamental in several parts of the world. Previous studies have revealed that Jerusalem artichoke can be grown in Portugal, producing high tuber yields when the crop is regularly watered and moderately fertilized with nitrogen [1]. In recent years there has been an in...

Prevalence and geographical distribution of Senotainia tricuspis (Meigen)

The aim of this work was to survey the prevalence of Senotainia sp. (Diptera, Sarcophagidae) in several Portuguese regions. A total of 61182 bees were sampled from 1912 Portuguese apiaries, distributed in several regions of Portugal and were analyzed for Senotainia sp prevalence. The bees samples were collected during 2009 and the thoraxes of 40 bees taken from each sample were examined individually in Referenc...

Estudio de la incidencia de enfermedades de la cría de abejas en dos regiones d...

En la actualidad, las enfermedades de las abejas representan un problema grave que los apicultores tienen que afrontar, tanto a nivel nacional como mundial. El diagnóstico del laboratorio de las enfermedades de las abejas melíferas es una herramienta clave para su control, ya que la detección precoz es importante, no solo para prevenir la propagación como también para la toma de decisiones en el momento de real...

Optic disc detection by earth mover's distance template matching

This paper presents a method for the detection of OD in the retina which takes advantage of the powerful preprocessing techniques such as the contrast enhancement, Gabor wavelet transform for vessel segmentation, mathematical morphology and Earth Mover’s distance (EMD) as the matching process. The OD detection algorithm is based on matching the expected directional pattern of the retinal blood vessels. Vessel s...

Beef burgers patties incorporated with Boletus edulis extracts: lipid peroxidat...

The objective of this study was to analyse the lipid peroxidation inhibition in beef burgers after incorporation of Boletus edulis extracts in different concentrations. Beef burgers samples were stored for 8 days, and chemical and nutritional parameters, including the profile in free fatty acids, were evaluated. Furthermore, the inhibition of thiobarbituric acid reactive substances (TBARS) formation, free radic...

Diagnóstico laboratorial de enfermedades de la cría de abejas en el Nordeste de...

EI objetivo de este trabajo fue determinar la prevalencia y la dispersión de las enfermedades de cría de las abejas en el Noreste de Portugal. Muestras de cría de abejas melíferas fueron recogidas y enviadas al laboratorio de Patología Apícola de la Eso la Superior Agraria de Bragança (LPAESAB). Dichas muestras fueron recogidas en los años 2008 y 2009 Y se procesaron para la evaluación de las enfermedades de la...
