Improving fECG signal acquisition in the evaluation of fetal well-being

The ability to monitor fetal heart rate is vital during late pregnancy and labor in order to evaluate fetal well-being. Current monitoring practice is essentially based on external cardiotocography and, less frequently, during labor, invasive fetal scalp electrocardiography. Many current and envisaged applications could benefi t from simpler devices using a 3-lead ECG confi guration. We are designing a maternity support belt with an embedded wireless 3-lead ECG sensor, and have investigated the infl uence of the ground electrode position on signal quality. Data from over 100 pregnant women was collected with the ground electrode placed in 3 locations in order to determine optimum electrode placement and belt form factor.

A Igreja Católica nas origens do salazarismo

As relações entre a Igreja Católica e o Estado Novo constituem uma peça importante da historiografia portuguesa contemporânea. Sendo esta uma questão que está longe de ser consensual, sobretudo porque tem implícita a definição da natureza do regime, revela-se fundamental recuperar os seus fundamentos, através de uma análise do tipo de relacionamento estabelecidos entre as duas instituições nos primeiros anos do salazarismo.

Sensitivity of Gomez-Nuñez boxes for the detection of household infestation with Panstrongylus megistus

Four methods for detecting household infestations with Panstrongylus megistus were compared: 1) manual collection; 2) collection after pyrethrum application; 3) search viable eggs; and 4) Gomez-Nuñez boxes. Manual collection was the most sensitive method (23% infested), followed by pyrethrum (21%), Gomez-Nuñez boxes (15%) and viable eggs (12%). About 10% of infested houses were positive exclusively on the Gomez-Nuñez box test. More over, 6 out of the 7 houses positive exclusively on the Gomez-Nuñez method were located in a recently sprayed area, where P. megistus density was low. Inspection of Gomez-Nuñez boxes at 12 weekspost-application was twice as effective as inspection at 6 weekspost-application. Triatomine feces was the most common evidencefor thepresence of P. megistus found within Gomez-Nuñez boxes. Gomez-Nuñez boxes area a useful adjunct to manual collection in detecting domestic infestations with P. megistus, especially in areas where bug densities are low. However, the utility of Gomez-Nuhez boxes must be weighed against the time and labor they require.

A relação entre gárgulas e textos no contexto tardo-medieval em Portugal: preocupações em torno do comportamento do corpo e os pecados

Resumo: O nosso propósito é analisar a relação entre gárgulas e textos no contexto português dos sécs. XV e XVI. Neste âmbito serão analisadas algumas gárgulas, bem como programas iconográficos de gárgulas, que evidenciam as mesmas preocupações que os textos, com destaque especial para o comportamento do corpo, para os pecados. Deste confronto resultará não só a profunda relação das gárgulas com a sua época, mas em particular a sua vocação pedagógica, numa relação estreita com a igreja e com o seu públicoalvo. Abstract: Our aim is to analyze the relationship between gargoyles and some Portuguese texts in the context of 15th and 16th centuries. In this purpose some gargoyles will be observed, as well as the iconographic programs that highlight the same concerns as the chosen texts, with special emphasis on the behaviour of the sinful body. From this phenomenon will result not only a deep relationship between gargoyles and late medieval ages, but in particular its educational role that results from a close relationship with the church and with its audience.

Portugal Telecom

This Masters Thesis aims to be used in class for teaching purposes. The primary objective of the case is to understand the way critical anti-takeover measures can be used in a hostile takeover environment. The case portrays not only all defensive tools used by PT against Sonaecom (conditioned by the Portuguese Securities Code) but also all major interactions with relevant stakeholders. Communication is positioned as a central tool to stakeholders’ interaction. As a consequence of that, students are supposed to comprehend how PT used this instrument to implement its defensive strategy. This Masters Thesis was written essentially from PT’s perspective but it also includes all available Sonacom’s public statements and data. It joins several different points of view (from PT’s CEO and top management to PT’s employees and labor unions). Therefore, it is not supposed to mach exactly to one’s perspective of Sonecom’s takeover attempt but instead to be an aggregate view of the case. The mains idea is to promote debate in order to create an interactive class environment among session’s attendants. Main areas developed in this Thesis are Mergers and Acquisitions, Corporate Communication and Corporate Governance. The case's recommended questions are in line with these areas. Suggested answers for these questions are balanced with some academic documentation that can be complemented with some in-class notes according to the session's objectives.

Assisted Reproductive Technologies (ART) in a Model of Fertility Choice

This paper provides a simple theoretical framework to discuss the relationship between assisted reproductive technologies and the microeconomics of fertility choice. Individuals make choices of education and work along with decisions about whether and when to have children. Decisions regarding fertility are influenced by policy and labor market factors that affect the earnings opportunities of mothers and the costs of raising children. We show how observed differences in these economic factors across countries explain observed different fertility and childbearing age patterns. We then use the model to predict behavioral responses to biomedical improvements in assisted reproductive technologies, and hence the impact of these technologies on fertility.

The problem of the competitiveness of nuclear energy: a biophysical explanation

In this study I try to explain the systemic problem of the low economic competitiveness of nuclear energy for the production of electricity by carrying out a biophysical analysis of its production process. Given the fact that neither econometric approaches nor onedimensional methods of energy analyses are effective, I introduce the concept of biophysical explanation as a quantitative analysis capable of handling the inherent ambiguity associated with the concept of energy. In particular, the quantities of energy, considered as relevant for the assessment, can only be measured and aggregated after having agreed on a pre-analytical definition of a grammar characterizing a given set of finite transformations. Using this grammar it becomes possible to provide a biophysical explanation for the low economic competitiveness of nuclear energy in the production of electricity. When comparing the various unit operations of the process of production of electricity with nuclear energy to the analogous unit operations of the process of production of fossil energy, we see that the various phases of the process are the same. The only difference is related to characteristics of the process associated with the generation of heat which are completely different in the two systems. Since the cost of production of fossil energy provides the base line of economic competitiveness of electricity, the (lack of) economic competitiveness of the production of electricity from nuclear energy can be studied, by comparing the biophysical costs associated with the different unit operations taking place in nuclear and fossil power plants when generating process heat or net electricity. In particular, the analysis focuses on fossil-fuel requirements and labor requirements for those phases that both nuclear plants and fossil energy plants have in common: (i) mining; (ii) refining/enriching; (iii) generating heat/electricity; (iv) handling the pollution/radioactive wastes. By adopting this approach, it becomes possible to explain the systemic low economic competitiveness of nuclear energy in the production of electricity, because of: (i) its dependence on oil, limiting its possible role as a carbon-free alternative; (ii) the choices made in relation to its fuel cycle, especially whether it includes reprocessing operations or not; (iii) the unavoidable uncertainty in the definition of the characteristics of its process; (iv) its large inertia (lack of flexibility) due to issues of time scale; and (v) its low power level.
