Copper-driven avoidance and mortality in temperate and tropicaltadpoles

Amphibians have experienced an accentuated population decline in the whole world due to many factors,one of them being anthropogenic contamination. The present study aimed to assess the potential effect ofcopper, as a worldwide and reference contaminant, on the immediate decline of exposed population dueto avoidance and mortality responses in tadpoles of three species of amphibians across climatic zones:a South...

Copper-driven avoidance and mortality in temperate and tropical tadpoles

Amphibians have experienced an accentuated population decline in the whole world due to many factors, one of them being anthropogenic contamination.

Understanding information security culture: a survey in small and medium sized ...

Information security is a relevant fact for current organizations. There are factors inextricably linked to this issue, and one cannot talk about information security in an organization without addressing and understanding the information security culture of that institution. Maximizing the organizational culture within an organization will enable the safeguard of information security. For that, we need to unde...

Numa escola que se encontra em transformação no sentido de se adaptar aos contextos sociais, culturais e políticos que a rodeiam, cabe aos professores serem agentes ativos na definição do caminho a percorrer, visando o aumento da qualidade educativa a proporcionar aos nossos jovens. O questionamento inerente à reflexão sobre o percurso profissional levou à identificação da situação problema e à formulação daque...

Site-condition map for Portugal based on Vs30 values and evaluation of the appl...

Maps providing information on site conditions are essential tools to accurately represent the spatial distribution of ground motions, both in seismic hazard maps and in instrumental intensity maps (ShakeMaps). Project SCENE, funded by the Portuguese Foundation for Science and Technology, aims at characterizing the site conditions for Portugal and to outline a first-order site effects map to be used in seismic h...

Development and validation of an experimental life support system for assessing...

An experimental life support system (ELSS) was constructed to study the interactive effects of multiple stressors on coastal and estuarine benthic communities, specifically perturbations driven by global climate change and anthropogenic environmental contamination. The ELSS allows researchers to control salinity, pH, temperature, ultraviolet radiation (UVR), tidal rhythms and exposure to selected contaminants. ...

On the use of quality tools : a case study

Organizations need to improve their processes to continually achieve customer satisfaction and, to do that in an effective and efficient way, should use quality tools. The main objective of this research project is to improve the level of quality through the use of quality tools in a company in the installation phase. The PDCA cycle is applied as a methodology to trigger the use of quality tools in problems sol...

Quantification of uncertainty of performance measures using graph theory

In this paper, the graph theory is used to quantify the uncertainty generated in performance measures during the process of performance measurement. A graph is developed considering all the sources of uncertainty present in this process and their relationship. The permanent function of the matrix associated with the graph is used as the basis for determining an uncertainty index.
