De forma a realizar estudos de escoamentos em microcanais e avaliar a influência das nanopartículas, sob a ação de um campo magnético estático, na espessura da camada de plasma, foram produzidas nanoparticulas de óxido de ferro por síntese solvotérmica, sendo posteriormente colocadas em suspensão num fluido fisiológico constituído por eritrócitos. Verificou-se que as nanopartículas com características magnética...
In the present work, in vitro blood flowing through a bifurcation microchannel was studied. The aim was to measure the Trajectories of the cell-free layer (CFL) by using different methods, i. e., a manual and two automatic methods.

No presente estudo, pretendeu-se desenvolver/melhorar uma metodologia de microfabricação de baixo custo, conhecida por xurografia e efectuar a visualização e quantificação da camada livre de células (CLC) junto às paredes para diferentes escoamentos sanguíneos em microcanais.
The main aim al this paper was to study the advance of the breeding season in Portuguese Serrana goats using a short-term progestagen treatment (PGF2alpha + FGA) and eCG associated or not to a previous melatonin treatment. In March, 35 adult Serrana goats were randomly divided in two groups: about half the goats received a subcutaneous implant of melatonin (18 mg) as the others got no treatment. Fifty days afte...
This work aimed to compare two different protocols - FGA + eCG and melatonin + FGA + eCG - commonly used to control the breeding activity in Churra Galega Bragançana ewes. The effect of time at eCG administration - 24 hours before or at sponge withdraw - was also assessed. ln March, 94 adult ewes were randomly divided in two groups: 25 received a subcutaneous implant of melatonin (18 mg) as the others 69 got no...
The main aim of this paper was to study the effects of different breeding - natural mounting vs. artificial insemination - and hormonal control protocols - melatonin + FGA + eCG vs. FGA + eCG - on the reproduction activity of Portuguese Serrana goats in the anestrous season. ln March, 60 adult Serrana goats were randomly divided in two groups: half the goats received a subcutaneous implant of melatonin (18 mg) ...
This work aimed to assess if a pre-treatment with melatonin may improve the efficiency of a short-term progestagen treatment in advancing the breeding season in Churra Galega Bragançana ewes. The effects of eCG and hCG were also assessed. ln March, 65 adult ewes were randomly divided in two groups: 28 received a subcutaneous implant of melatonin (18 mg) as the others 37 got no treatment (Control). Forty-live da...
This study aimed to evaluate the efficiency of different hormonal treatments to control the breeding activity in Churra Galega Bragançana (CGB) ewes. Material and Methods This experiment took place at Bragança (latitude 41° 49' N, longitude 6° 40' W, altitude 720 meters) and involved 94 adult CGB ewes. At March 9, 25 ewes received a melatonin implant (18 mg) – Melatonin. Forty-five days later a vaginal sponge w...
