What is the impact of kelp forest density and/or area on fisheries?
Araujo, Rita M.; Bartsch, Inka; Bekkby, Trine; Erzini, Karim; Sousa-Pinto, I.Background Kelp forests are highly productive ecosystem engineers of rocky cold-water marine coastlines, providing shelter, habitat and food for a variety of associated organisms. Several factors have been related with an observed trend of kelp deforestation in some regions of the globe. The effect of this trend on fisheries has been poorly studied. The European directives addressing the conservation of marine ...
Attachment, Physiological and Familial Vulnerability in Childhood Obesity: an ...
Pinto, I; Oliveira, L; Pinto, M; Calhau, C; Coelho, RThe aims of the present study were to test the association between insecure attachment and basal cortisol and catecholamines levels in a sample of obese children. The role of familial vulnerability and gender was also investigated. Methods: Cortisol and catecholamines levels of 8- to 13-year olds obese children were measured. Self-report questionnaires were used to assess attachment pattern and current anxiety ...
Variation of growth ring width in maritime pine (Pinus pinaster Ait.)
Anjos, O.; Margarido, M.; Pinto, I.; Usenius, A.; Pereira, H.The aim of this study was to incorporate ring width data into sawing yield strudies through simulation and tree modelling techniques. Results on data analysis measuring anual growth variation contribute also to the raw material characterisation.
Effects of disturbance on marginal populations: Human trampling on Ascophyllum ...
Araújo, R.; Vaselli, S.; Almeida, M.; Serrão, Ester; Sousa-Pinto, I.The negative effects of disturbances on the long-term persistence of populations may be more severe in marginal populations, i.e. those occurring at the boundaries of geographical and eco- logical distribution ranges. Human trampling is an important source of anthropogenic disturbance for intertidal assemblages. Effects of human trampling on intertidal rocky shore assemblages dominated by Ascophyllum nodosum (L...
Synthesis and characterization of membranes obtained by graft copolymerization ...
Santos, K. S. C. R. dos; Coelho, J. F. J.; Ferreira, P.; Pinto, I.; Lorenzetti, S. G.; Ferreira, E. I.; Higa, O. Z.; Gil, M. H.Chitosan based membranes to be applied on wound healing as topical drug delivery systems were developed by graft copolymerization of acrylic acid (AA) and 2-hydroxyethyl methacrylate (HEMA) onto chitosan using cerium ammonium nitrate as chemical initiator. Evidence for graft copolymerization of the vinyl monomers onto chitosan was obtained by FTIR and DMTA. Swelling degree, cytotoxicity, thrombogenicity and hae...
ECG wave detector and delineation with wavelets
Ortigueira, M.D.; Alves, L. B.; Batista, A. G.; Pinto, I. V.Proceedings of the International Conference on Computational Intelligence in Medicine Healthcare, CIMED 2005, Costa da Caparica, June 29 - July 1, 2005 ; Efficient R wave detection is a crucial preprocessing step of most of the ECG signal analysis . Likewis e, ECG delineation comprising P wave and QRS complex, is required for ECG processing, namely in High- Resolution Electrocardiography (HR-ECG). We have perf...
Caracterização da variação da espessura dos anéis de crescimento em Pinheiro Bravo
Pereira, H.; Margarido, M.; Pinto, I.; Usenius, A.; Anjos, O.Comunicação apresentada no 5.º Congresso Florestal Nacional que decorreu em Viseu em Maio de 2005. ; Com este trabalho pretende-se dar um contributo para o estudo dos factores de variação radial e axial da espessura dos anéis de crescimento de pinheiro bravo. O trabalho foi desenvolvido com base em técnicas de análise de imagem e tem como objectivo final incluir a variação dos anéis de crescimento na qualidade...
Caracterização da variação da espessura dos anéis de crescimento em pinheiro bravo
Margarido, M.; Pinto, I.; Pereira, H.; Usenius, A.; Anjos, O.Com este trabalho pretende-se dar um contributo para o estudo dos factores de variação radial e axial da espessura dos anéis de crescimento de pinheiro bravo. O trabalho foi desenvolvido com base em técnicas de análise de imagem e tem como objectivo final incluir a variação dos anéis de crescimento na qualidade dos produtos finais serrados da madeira desta espécie.

Chronic hemodialysis with acetate in patients over 70 years old.
Neves, P L; Serviço de Nefrologia, Hospital Distrital de Faro.; Bexiga, I; Pinto, I; Amorim, J PDuring the last years there has a significant increase of elderly patients included in chronic dialysis programs. No agreement has been reached about the preferable treatment modality. In this study we analyse our experience in the management of patients over 70 years of age undergoing chronic acetate hemodialysis (HDCA). Sixty four of those patients have initiated HDCA between May 1982 and December 1990 (Mean ...
