Original plant diversity and ecosystems of a small, remote oceanic island (Corv...
Connor, Simon E.; Lewis, Tara; van Leeuwen, Jacqueline F.N.; van der Knaap, W.O. (Pim); Schaefer, Hanno; Porch, Nicholas; Gomes, Ana I.Remote islands harbour many endemic species and unique ecosystems. They are also some of the world's most human-impacted systems. It is essential to understand how island species and ecosystems behaved prior to major anthropogenic disruption as a basis for their conservation. This research aims to reconstruct the original, pre-colonial biodiversity of a remote oceanic island to understand the scale of past exti...
Ozone membrane contactor for tertiary treatment of urban wastewater: Chemical, ...
Presumido, Pedro Henrique; Ribeirinho-Soares, Sara; Montes, Rosa; Quintana, Jose B.; Rodil, Rosário; Ribeiro, Marta; Neuparth, Teresa; Santos, Miguel M.A membrane ozone contactor, operated under continuous mode, was applied to promote the tertiary treatment of urban wastewater (UWW), targeting the removal of contaminants of emerging concern (CECs), bacterial disinfection, and toxicity reduction. This system relies on the homogeneous radial distribution of ozone (O3) in the reaction zone by "titration" through a microfiltration borosilicate tubular membrane, wh...
Multistage treatment for olive mill wastewater: Assessing legal compliance and ...
Vuppala, Srikanth; Paulista, Larissa Oliveira; Morais, Daniela F.S.; Pinho, Inês L.; Martins, Ramiro; Gomes, Ana I.; Moreira, Francisca C.A treatment train for the remediation of a raw olive mill wastewater (OMW) was investigated, aiming to comply with the emission limit values (ELVs) for direct discharge into water bodies. The following stages were proposed: (i) pre-treatment (filtration and sedimentation), (ii) coagulation, (iii) biological oxidation, and (iv) advanced oxidation process (AOP). Under the best-operating conditions for coagulation...
Ozone membrane contactor to intensify gas/liquid mass transfer and contaminants...
Presumido, Pedro Henrique; Montes, Rosa; Quintana, Jose B.; Rodil, Rosário; Feliciano, Manuel; Li Puma, Gianluca; Gomes, Ana I.; Vilar, Vítor J.P.A tubular porous borosilicate membrane contactor was investigated for ozone gas/water mass transfer and the removal of contaminants of emerging concern (CECs) in water. Ozone gas/water contact occurs on the mem-brane shell-side, which is coated with a photocatalyst (TiO2-P25), as the ozone gas stream is fed from the lumen side and permeates through the pores generating micro-sized ozone bubbles uniformly delive...
Multiple linear and principal component regressions for modelling ecotoxicity b...
Gomes, Ana I.; Pires, José C.M.; Figueiredo, Sónia Adriana; Boaventura, RuiThe ecotoxicological response of the living organisms in an aquatic system depends on the physical, chemical and bacteriological variables, as well as the interactions between them. An important challenge to scientists is to understand the interaction and behaviour of factors involved in a multidimensional process such as the ecotoxicological response.With this aim, multiple linear regression (MLR) and principa...
Optimization of River Water Quality Surveys by Multivariate Analysis of Physico...
Gomes, Ana I.; Pires, José C.M.; Figueiredo, Sónia Adriana; Boaventura, RuiThis study aims to optimize the water quality monitoring of a polluted watercourse (Leça River, Portugal) through the principal component analysis (PCA) and cluster analysis (CA). These statistical methodologies were applied to physicochemical, bacteriological and ecotoxicological data (with the marine bacterium Vibrio fischeri and the green alga Chlorella vulgaris) obtained with the analysis of water samples m...
Assessment of nursing students and nurses' orientation towards patient-centered...
Grilo, Ana Monteiro; Santos, Margarida Custódio dos; Rita, Joana S.; Gomes, Ana I.Background - Being patient centered is a core value for nursing. Patient centered-care has been related to patient and health provider satisfaction, better health outcomes, higher quality of care and more efficient health care delivery. Objectives - The purpose was to assess the orientation adopted by nurses and students in patient care, using The Patient-Practitioner Orientation Scale, as well as to compare th...
