Apple and pear represent 51% of fresh fruit orchards in Portugal. This paper presents a life-cycle (LC) greenhouse gas (GHG) assessment (so-called carbon footprint) of 3 apple and 1 pear Portuguese production systems. An LC model and inventory were implemented, encompassing the farm stage (cultivation of fruit trees in orchards), storage and distribution (transport to retail). The functional unit considered in ...
We conducted a study of the phenology of four cultivars of Olea europaea L. ('Arbequina', 'Cobrançosa', 'Galega Vulgar' and 'Picual') based on observations of phenological stages, flowering times and modeling the flowering dates, using as reference an olive grove in Elvas. We conducted a modeling study of flowering dates following the model of De Melo Abreu et al. (2004). In the year 2011 the floral initiation ...
Prediction of flowering of olive trees should account for chilling requirements, using an appropriate chilling unit for the accounting of chilling accumulation. After chilling requirements are satisfied, dormancy break takes place. Thereafter, the trees enter the forcing phase, in which the thermal time approach is used, but an appropriate base temperature must be determined. Such a model was developed, calibra...
Os dados para a calibração e validação dos modelos resultam dum projeto FCT que se encontra no terceiro ano. Abrange quatro cultivares (Arbequina, Cobrançosa, Galega, Picual), quatro localizações principais (Mirandela, Santarém, Elvas e Moncarapacho). Os dados das temperaturas horárias foram obtidos a partir de estações meteorológicas localizadas na vizinhança dos ensaios. Os dados do vingamento foram obtidos a...
A qualidade do azeite pode ser um elemento diferenciador, permitindo a prática de melhores preços num mercado cada vez mais competitivo. Os constituintes que mais têm sido apontados como tendo propriedades benéficas para a saúde são a composição acídica elevada em monoinsaturados, os valores elevados de tocoferóis, nomeadamente do atocoferol (vitamina E), e de polifenóis. A cultivar, a temperatura e o índice de...
A severe cutaneous reaction in a female dog after administration of penicillin and cephalexin is described, in which the main signs presented by the patient were fever, lack of appetite, and detachment of epidermis in the dorsal region of body.The established treatment was surgical debridement of the region, topical application of Aloe Vera with sugar, and systemic antibiotic therapy with ciprofloxacin, resulti...
Avaliou-se o efeito da adição de diferentes tipos e concentrações de soro sobre o desenvolvimento e a sobrevivência de folículos ovarianos pré-antrais (FOPA) caprinos in vitro. Além disso, verificou-se a relação entre as concentrações de nitrito presentes no meio de cultivo e a viabilidade folicular. Cada par ovariano foi dividido em 29 fragmentos, sendo um destinado ao controle. Os fragmentos foram cultivados ...
It was reported a case of a 9-year-old Brazilian Fila male dog that had been affected by a tissular formation of the nictitant membrane of the right eye with four months of evolution. Conjunctival hyperemia and edema, serosanguinolent secretion, and a conjunctival neoformation at the nictitant membrane were observed. Surgical exeresis of the neoformation was performed. Endothelial cells slightly differentiated ...
One dog with visceral leishmaniasis is reported presenting cutaneous lesions, cachexia, and corneal ulceration. Parasitological and serological diagnoses were performed by exam of contents of the aspirative punction of the bone marrow and by immunofluorecence, respectively. Amastigota forms resembling Leishmania sp. were visualized by citology.
Keratoconjunctivitis sicca is characterized by qualitative or quantitative abnormalities in the aqueous component of the tear film and is frequent in dogs with distemper. Twenty-eight third eyelid glands of end-stage dogs that died from distemper were analyzed by light microscopy. Keratoconjunctivitis sicca was diagnosed based on ophthalmic findings regarding alterations in the ocular surface and by the Schirme...
