Machado, M.; Dinis, A. M.; Santos-Rosa, M.; Alves, V.; Salgueiro, L.; Cavaleiro, C.; Sousa, M. C.In the search for new leishmanicidal agents, Thymus capitellatus Hoffmanns. & Link (familyLamiaceae) volatile extract and its major compounds, 1,8-cineole and borneol, were testedagainst Leishmania infantum, Leishmania tropica and Leishmania major. Plant volatile extract(essential oil) was analysed by GC and GC–MS and the activity of essential oil on Leishmaniapromastigotes viability was assessed using tetrazol...
A test for directional-linear independence, with applications to wildfire orien...
GarcÃa-Portugués, Eduardo; Barros, Ana M.G.; Crujeiras, Rosa M.; González-Manteiga, Wenceslao; Pereira, J.M.C.Original Paper ; A nonparametric test for assessing the independence between a directional random variable (circular or spherical, as particular cases) and a linear one is proposed in this paper. The statistic is based on the squared distance between nonparametric kernel density estimates and its calibration is done by a permutation approach. The size and power characteristics of various variants of the test a...
Simulated hemodynamics in human carotid bifurcation based on Doppler ultrasound...
Luísa C. Sousa; Catarina F. Castro; Carlos C. António; João M.R.S. Tavares; André M.F. Santos; Rosa M. Santos; Pedro Castro; Elsa AzevedoBackground: Atherosclerotic lesions commonly develop at arterial branch sites. Noninvasive carotid artery ultrasound is a well-established and effective method which allows real-time images and measurements of flow velocities. We aimed to develop a methodology for patient-specific computational 3D reconstruction and blood flow simulation based on ultrasound image data. Material and Methods: Subject-specific stu...

Stabilisation/solidification of APC residues from MSW incineration with hydraul...
Quina, Margarida J.; Bordado, João C. M.; Quinta-Ferreira, Rosa M.This study focuses on the stabilisation/solidification (S/S) treatment of air pollution control (APC) residues from municipal solid waste (MSW) incineration. Six formulations (T1–T6) were tested based on different cements as binders, for the immobilisation of pollutants and to prevent their entering into the environment at unacceptable rates. Soluble phosphates and silicates were considered in some cases to fix...
Susceptibility of the Basin of River Bengalas to Landslides
Silva, L.T.; Sampaio, E.P.; Corte-Real, J.A.; Camarinha, P.I.; Rosa, M.B.; Mira, G.C.; Moraes, B.E.; França, D.G.Landslides have frequently occurred in last years, due to the disorderly grownth of the cities and the occupation of risk areas by the poor population, causing social, environmental and economic impacts. Urban areas in expansion move to geologically unstable areas and topographically inclined, such as the Basin of River Bengalas, located in the city of Nova Friburgo, mountainous re...
Metátese na linguagem infantil: “porfessora” é bom, “professora” é melhor
Lima, Rosa M.; Centro de Estudos da Criança (CESC), Universidade do Minho Escola Superior de Educação Paula FrassinettiChildren often learn to read and write when their oral language is still marked by subtle errors. Metathesis is one such error. It is a phonological process whereby the order of phonemes is interchanged in the word, such as “corcodilo” instead of “crocodilo”. We investigated metathesis in child language. In a first study, we investigated spoken language acquisition from 3 to7 and half years of age. Metathesis i...
The relationship between weight status and psychopathology in adolescence : the...
Rosa, M. F.; Gonçalves, Sónia Ferreira; Antunes, HenedinaPublished online before print April 12, 2013 ; This study evaluated the differences between normal-weight and overweight adolescents in psychopathology, social support and emotional competences, and the role of social support in the relationship between psychopathology and weight. We examined a clinical group of 83 overweight/obese adolescents, a community group of 82 overweight/obese adolescents, and 205 adol...
Co-composting of eggshell waste in self-heating reactors: monitoring and end pr...
Soares, Micaela A. R.; Quina, Margarida M. J.; Quinta-Ferreira, Rosa M.Industrial eggshell waste (ES) is classified as an animal by-product not intended to human consumption. For reducing pathogen spreading risk due to soil incorporation of ES, sanitation by composting is a pre-treatment option. This work aims to evaluate eggshell waste recycling in self-heating composting reactors and investigate ES effect on process evolution and end product quality. Potato peel, grass clippings...
Determination of airborne nanoparticles from welding operations
Gomes, João Pereira; Albuquerque, Paula Cristina; Miranda, Rosa M.; Vieira, Maria TeresaThe aim of this study is to assess the levels of airborne ultrafine particles emitted in welding processes (tungsten inert gas [TIG], metal active gas [MAG] of carbon steel, and friction stir welding [FSW] of aluminum) in terms of deposited area in pulmonary alveolar tract using a nanoparticle surface area monitor (NSAM) analyzer. The obtained results showed the dependence of process parameters on emitted ultra...
