Epidemiology of malaria, schistosomiasis, geohelminths, anemia and malnutrition in the context of a demographic surveillance system in Northern Angola

Background: Malaria, schistosomiasis and geohelminth infection are linked to maternal and child morbidity and mortality in sub-Saharan Africa. Knowing the prevalence levels of these infections is vital to guide governments towards the implementation of successful and cost-effective disease control initiatives. Methodology/Principal Findings: A cross-sectional study of 1,237 preschool children (0–5 year olds), 1,142 school-aged children (6–15 year olds) and 960 women (.15 year olds) was conducted to understand the distribution of malnutrition, anemia, malaria, schistosomiasis (intestinal and urinary) and geohelminths in a north-western province of Angola. We used a recent demographic surveillance system (DSS) database to select and recruit suitable households. Malnutrition was common among children (23.3% under-weight, 9.9% wasting and 32.2% stunting), and anemia was found to be a severe public health problem (i.e., .40%). Malaria prevalence was highest among preschool children reaching 20.2%. Microhematuria prevalence levels reached 10.0% of preschool children, 16.6% of school-aged children and 21.7% of mothers. Geohelminth infections were common, affecting 22.3% of preschool children, 31.6% of school-aged children and 28.0% of mothers. Conclusions: Here we report prevalence levels of malaria, schistosomiasis and geohelminths; all endemic in this poorly described area where a DSS has been recently established. Furthermore we found evidence that the studied infections are associated with the observed levels of anemia and malnutrition, which can justify the implementation of integrated interventions for the control of these diseases and morbidities.

Implementation of proton therapy in the portuguese context of radiotherapy

Cancer is a national and international health care concern. It’s important to find strategies for early diagnosis as well as for the optimization of the various therapeutic options currently existing in Portugal. Cancer is the second leading cause of death in Portugal, the choice of this study, is due to the importance of radiotherapy approach in cancer treatment and because is the therapy used in 40% of oncology patients. Radiation therapy has evolve data technological level, that allows new treatment techniques that are more efficient and that also promotes greater professional satisfaction. The hadrons are charged particles, used in cancer therapy. These particles can bring a paradigm shift regarding the therapeutic approach in radiotherapy. The technique used is proton therapy, that reveal to be more accurate, efficacious and less toxic to surrounding tissue. Proton therapy may be a promising development in the field of oncology and how the treatment is given in radiotherapy. Although there is awareness of the benefits of proton therapy in oncology it’s also important to take in consideration the costs of these therapy, because they are considerably higher than conventional treatments of radiotherapy. Given the lack of a proton therapy service in Portugal, this study aims to be a documentary analysis of clinical records that will achieve the following objectives: to identify the number of cancer patients diagnosed in 2010 in Portugal and to calculate the estimated number of patients that could have been treated with proton therapy according to the Health Council of the Netherlands registration document.

Publicidade interactiva na televisão em Portugal e no mundo

Num contexto de mudança a nível de hábitos sociais em que impera a necessidade de comunicar de uma forma mais natural e instantânea quanto possível, o cada vez mais informado e exigente consumidor tem vindo a adquirir um papel mais participativo na comunicação e construção das marcas. Se outrora assistíamos passivamente a uma comunicação unidirecional e desprovida de interactividade, hoje impera a possibilidade de podermos manipular ou construir conteúdos de acordo com as nossas necessidades e preferências individuais. Neste contexto, a comunicação nos novos meios tecnológicos tem procurado responder à dispersão de atenção por parte do consumidor, que se socorre simultaneamente de diversos ecrãs. Porém, no ecrã em que o novo consumidor mais despende o seu tempo, e com o qual ainda se sente mais à vontade, a televisão, a comunicação interactiva ainda se encontra pouca explorada. Para os profissionais de publicidade, e sobretudo para os anunciantes, o conceito de publicidade interactiva, quando inserida no meio televisivo, é deveras recente, carecendo de um maior aprofundamento teórico e empírico. Tendo em vista este aprofundamento, o objectivo geral deste trabalho consiste na caracterização do panorama da publicidade interactiva na televisão em Portugal tendo como termo de comparação o estrangeiro. A dissertação assumiu a forma de um estudo exploratório e misto sequencial, desenvolvido com base na análise de conteúdo de um conjunto de casos nacionais de Publicidade Interactiva na Televisão fornecidos pelo MEO e de casos estrangeiros publicados na Internet. Assentando a análise numa grelha própria, procurou caracterizar-se o panorama actual da Publicidade Interactiva na Televisão nacional tendo como termo de comparação o que se passa lá fora, do ponto de vista dos conteúdos, da partilha destes, da dependência de um second screen e dos objectivos subjacentes aos anúncios. Foi possível concluir com este estudo que, apesar de a Publicidade Interactiva na Televisão se encontrar mais desenvolvida no estrangeiro, em Portugal observaram-se características singulares e positivas, o que aponta que nos encontramos a evoluir a passos largos para alcançar melhores experiências interactivas.

O declínio e a ascensão da comunicação word-of-mouth

As questões de liderança de opinião tornaram-se um tema cada vez mais interessante na nossa contemporaneidade. Quer se considere, ou não, que os ditos “novos media” provocaram uma revolução na forma como interagimos, o que é inquestionável é o seu papel na forma como somos influenciados e influenciamos, pelo menos, no que às sociedades ditas como desenvolvidas se refere. Partindo do interesse pelo estudo do word-of-mouth eletrónico, esta dissertação pretende contribuir para um melhor conhecimento do Twitter enquanto instrumento de influência. De um ponto de vista empírico este trabalho centrou-se na análise do Twitter de Arianna Huffington e dos seus seguidores no Twitter.

Simulation of rectifier voltage malfunction on OWECS, four-level converter, HVDC light link: Smart grid context tool

This paper presents a model for the simulation of an offshore wind system having a rectifier input voltage malfunction at one phase. The offshore wind system model comprises a variable-speed wind turbine supported on a floating platform, equipped with a permanent magnet synchronous generator using full-power four-level neutral point clamped converter. The link from the offshore floating platform to the onshore electrical grid is done through a light high voltage direct current submarine cable. The drive train is modeled by a three-mass model. Considerations about the smart grid context are offered for the use of the model in such a context. The rectifier voltage malfunction domino effect is presented as a case study to show capabilities of the model. (C) 2015 Elsevier Ltd. All rights reserved.
