Environmental and endocrine assessment of sheep welfare in a climate-controlled...

The nutritional status of sheep grazing in the Montado ecosystem varies considerably throughout the year, due to variations in the availability and quality of pastures, strongly influenced by the typical climatic conditions of the Mediterranean region: dry summer and autumn with very little rain. These variations lead to severely restricted feeding for approximately half the year, causing under-nutrition, limit...

Índice Proliferativo Ki-67 no Cancro Gástrico

Introdução: O cancro gástrico representa ainda uma das principais causas de mortalidade por doença oncológica a nível mundial, apesar da evolução substancial no seu tratamento. Diversos marcadores biológicos têm sido introduzidos com intuito prognóstico da doença. A proteína Ki-67 através de técnicas imunocitoquímicas tem sido utilizada como um indicador da actividade proliferativa tumoral. No cancro gástrico o...

Eye tracking data representation and visualization : on information and communi...

Eye tracking has become a preponderant technique in the evaluation of user interaction and behaviour with study objects in defined contexts. Common eye tracking related data representation techniques offer valuable input regarding user interaction and eye gaze behaviour, namely through fixations and saccades measurement. However, these and other techniques may be insufficient for the representation of acquired ...

Population mobility and the changing epidemics of HIV-2 in Portugal

INTRODUCTION: Portugal is the European country with the highest frequency of HIV-2 infection, which is mainly concentrated in West Africa. The cumulative number of notified HIV-2 infections in Portugal was 1813 by the end of December 2008. To better characterize the dynamics of HIV-2 infection in the country and to obtain data that may be of use in the prevention of the spread of HIV-2, we evaluated a large poo...

Mineralogical attenuation for metallic remediation in a passive system for mine...

Passive systems with constructed wetlands have been consistently used to treat mine water from abandoned mines. Long-term and cost-effective remediation is a crucial expectation for these water treatment facilities. To achieve that, a complex chain of physical, chemical, biological, and mineralogical mechanisms for pollutants removal must be designed to simulate natural attenuation processes. This paper aims to...

Use of high moisture corn silage replacing dry corn on intake, apparent digesti...

Twenty primiparous and multiparous Alpine breed goats at approximately 80 days of lactation were used in this experiment. The animals were housed individually in metal cages and distributed according to milk production in five 4 × 4 Latin squares. The experimental diets used in the experiment presented concentrate:forage ratio of 65:35. The treatments were characterized by increasing levels of 0, 33, 67 and 100...
