Phos4Cycle – Monitorização de fosfatos das atividades agropecuárias para a util...

A poluição do solo e da água por fosfatos, decorrente da agricultura e pecuária, representa um desafio crescente no espaço SUDOE (Portugal, Espanha e França). A elevada dependência da agricultura intensiva em fertilizantes solúveis e pouca reposição da matéria orgânica, têm resultado na degradação da qualidade dos solos e concentrações elevadas de nutrientes nas águas superficiais. O projeto Phos4Cycle visa pro...

Dual and sequential drug delivery systems with antimicrobial and bone regenerat...

Bone defect healing is often compromised by infections acquired during surgery, hindering regeneration. An effective solution should first prevent infection and then promote bone repair. Localised drug-delivery systems capable of dual and sequential release of antimicrobial and bone-regenerative agents represent a promising solution; however, precisely controlling this sequential release remains an unmet challe...

Health education projects in Portuguese schools: perceptions of its implementation

Children and young people need to be able to make responsible choices. This article aims to characterize the implementation of school projects focused on health promotion and education on students' learning and risk prevention in accordance with the perceptions of 14 school project coordinators, 13 school directors and 1 subdirector. Semi-structured interviews, individual and in pairs, were conducted implying 1...

Topography and hydrology modeling and influence on soil erosion simulation, at ...

Diffuse pollution from agricultural activities is a major environmental problem. The extent of the impacts is driven, e.g., by local topography due to the influence on hydrological processes. This study aims to investigate the use of dif-ferent scale topographic data in assessing runoff-erosion processes. The TopAG-NPS module, a component of the AnnAGNPS model (Annualized Agriculture Nonpoint Source), was used ...

What are forests for? Social perceptions of the functions of public-managed for...

Despite the growing research interest regarding the perceptions of forest-related stakeholders about forest functions and values, the views of social actors not directly involved in forestry have been largely overlooked, particularly in Southern European countries like Portugal. This article addresses this gap by analyzing the social perceptions regarding the functions of the Matas do Litoral, public-managed fo...

Modelação da topografia do terreno e simulação da erosão hídrica numa pequena b...

Na simulação dos impactes das atividades agrícolas na poluição difusa à escala da bacia hidrográfica, é importante uma adequada configuração topográfica do terreno e a compreensão do seu comportamento hidrológico. Neste estudo foi utilizado o módulo FlowNet Generator, componente do modelo AnnAGNPS (Annualized Agriculture Nonpoint Source), para avaliação da influência da resolução vertical do Modelo Digital do T...

The Polyvalent Day Hospital: Is there an excessive request of packed leucocyte-...

Background: The Polyvalent Day Hospital (PDH) allows the treatment of oncological diseases and chronic anemias on an outpatient basis, significantly improving the quality of life of these patients [1,2]. The lack of guidelines leads to variable transfusion practices between clinicians. Objective: The main aim of this study is to improve the management of resources used in the preparation of a transfusion unit. ...

Aritmética computacional

[Excerto] O objetivo de um método numérico é, como o próprio nome indica, produzir respostas numéricas a problemas matemáticos. Em calculo numérico a informação é transportada sob a forma de números. E, pois, fundamental ter um bom conhecimento de como os computadores ´ representam e operam com números, quais os erros cometidos e de que forma é que estes se podem avaliar e controlar. Este capítulo aborda os tóp...

PHONLAB Project: Coimbra – Harvard. Rethinking 20th-Century Scientific Centres ...

The aim of PHONLAB is to conduct a case study of the Coimbra Experimental Phonetics Laboratory (1936-1979). Created by Portuguese phonetician Armando de Lacerda (1902-1984), the laboratory attracted scientists from leading universities such as Harvard, Cambridge and Bonn, who sought specialist training in the use of innovative laboratory research techniques. How is it that in a country regarded as being scienti...
