A política externa portuguesa para os Países Africanos de Língua Portuguesa (PALOPS) : impactos e resultados do colonialismo luso nas relações internacionais africanas
O presente trabalho analisa as relações entre Portugal e os Países Africanos de Língua Portuguesa desde a colonização. A partir da política externa portuguesa para a África, que compreende o desenvolvimento das relações coloniais no século XV ao estabelecimento da CPLP é possível reconhecer a dependência sobretudo política de Portugal dos territórios africanos para manter-se como ator decisório nas relações internacionais. Destaca-se, para tanto, a dinamicidade e adaptabilidade da política externa do país ao longo das mudanças de cenário internacionais como a transição para o capitalismo moderno, o neocolonialismo, as independências coloniais, o fim da Guerra Fria e a reabertura do sistema internacional sob um cenário multipolar e cooperativo. A retomada das relações de Portugal com os PALOPS no pósindependência parte da negociação de benefícios internacionais mútuos do posicionamento conjunto. Assim a CPLP se forma como um mecanismo de inserção internacional para os PALOPS e manutenção da posição portuguesa entre os países centrais do sistema internacional.The present work analyzes the relations between Portugal and the African Portuguese-speaking Countries since colonization. From the Portuguese foreign policy towards Africa, which includes the development of colonial relations in the 15th century to the establishment of the CPLP, it is possible to recognize Portugal's mainly political dependence on African territories to remain a decisive actor in international relations. The dynamics and adaptability of the country's foreign policy during the changes in the international scenario, such as the transition to modern capitalism, neocolonialism, colonial independence, the end of the Cold War and the reopening of the international system under a multipolar and cooperative scenario stands out. The resumption of Portugal's relations with the PALOPS in the post-independence period starts from the negotiation of mutual international benefits of joint positioning. Thus, the CPLP is formed as a mechanism of international insertion for PALOPS and maintenance of the Portuguese position among the central countries of the international system
O ensino de uma habilidade complexa a indivíduos instituídos deficientes intelectuais : um relato de experiência
Dissertação (mestrado)—Universidade de Brasília, Faculdade de Educação, Programa de Pós-Graduação em Educação, 2015.O presente trabalho resulta da vivência da pesquisadora com cinco alunos instituídos deficientes intelectuais regularmente matriculados em uma instituição que atende pessoas com diagnóstico de deficiência intelectual e múltipla, em Brasília/ DF. Examina-se uma situação de ensino de uma habilidade complexa com os referidos alunos, utilizando como ferramenta o meio computacional e seus recursos de softwares mais básicos, favorecendo a construção do seu conhecimento. Por meio de narrativas do cotidiano vivido nas aulas realizadas no Laboratório de Informática com a participação dos alunos em uma atividade desenvolvida no Microsoft Excel, despertou-se o interesse dos alunos em participar de uma atividade que consistia na elaboração de uma planilha com controle de mercadoria e de entrada-saída de dinheiro. O estudo está estruturado em quatro capítulos. O primeiro capítulo aborda o ensino de uma habilidade complexa e o uso do computador como uma ferramenta pedagógica, além das visões fatalistas e eussêmicas do que venha a ser a deficiência. O segundo trata da educação como prática da libertação, tendo nos pressupostos de Freire um importante diálogo acerca do tema. O terceiro apresenta uma situação de ensino com esses alunos, e são descritas as estratégias utilizadas para auxiliar no desenvolvimento da atividade proposta. O quarto capítulo apresenta a análise e interpretação dos procedimentos adotados neste estudo. Finalmente, este estudo propõe-se a contribuir para uma reflexão acerca de estratégias de ensino utilizadas pelo professor que favoreçam a construção do conhecimento junto a indivíduos instituídos como deficientes intelectuais.This study results from the experience of the researcher with five intellectuals disabled instituted students enrolled in an institution that assists people diagnosed with intellectual and multiple disabilities in Brasilia / DF.

Used food oils: physical-chemical indicators of quality degradation
Comunicação apresentada em 11th Baltic Conference on Food Science and Technology “Food science and technology in achanging world” FOODBALT 2017 Conference Proceedings. Jelgava, LLUUsed food oil (UFO), designated as frying oil, is a residue. Degradation by reuse or during storage, may occur by contacting, chemical, enzymatic and microbiological pathways, but oxidation is a major concern of the industry, as it affects sensory and nutritional quality of edible oils, with potentially toxic compounds formation. In Portugal, UFO's main destination still is the sewerage system, an environmental problem and waste of raw material, which can be re-qualified for non-food uses. However, quality control applied to UFO's, often results into expensive analysis inappropriate for small laboratories and catering industry. This project, developed with the Musketeers Group Portugal co-promotion (2012-2016), aimed to identify low-cost physicochemical parameters for further implementation as UFO's Quality Degradation Indicators (QDI) indicating defects quickly and accurately. UFO's analysis was tested on the use, for industrial frying, and by degradation induced in the laboratory (frying and heat stability tests) by applying following parameters: moisture, water activity (a(w)), total acidity, peroxide index, iodine index, colour (CIE, CIE Lab), UV absorbency, total polar compounds and microbiological indicators. Internal procedures (ESAS) were validated, redefining working ranges and test conditions, as standards procedures did not provide reliable results for the entire life cycle of oils, whose profile changes with time and reuse. Results demonstrate significant differences with quick response parameters as Total Acidity, Peroxide Index and CIE Lab colour, outlined as QDI's. Moisture, aw and CIE Lab colour proved to be inadequate for this purpose. Iodine Index and UV Absorbency are more complex and time-consuming and were profiled as reference methods.info:eu-repo/semantics/publishedVersio
Phase Transformations in Duplex Stainless Steel: An Assessment by In Situ X-Ray Diffraction
Duplex stainless steels (commonly known as DSS) are a class of stainless steels with a microstructure formed by two main phases: ferrite and austenite. They are used in a wide range of applications, such as chemical processing, in maritime environments and in the oil and gas industries. In most cases, DSS are chosen based on their strength and corrosion resistance for various environments. When exposed to temperatures above 600°C though, the balance of alloying elements can be modified due to precipitation of various secondary phases, such as sigma (σ) and chi (χ). The sigma phase is typically enriched with Cr and Mo, so its formation can lead to a drastic deterioration in toughness, corrosion resistance, and weldability of duplex stainless steels. To prevent damages to these steels due to the formation of sigma phase, the understanding of such transformation becomes mandatory, not only during the development of these steels but also during their processing. In this research, samples from a lean duplex steel UNS S32304 are subjected to a temperature of 800°C and analyzed in situ by X-ray diffraction. Thus, the kinetics of phase transformations occurring in duplex stainless steels are observed in real time
Ecocardiograma e eletrocardiograma de cardiomiopatia dilatada em Dobermann - relato de caso: Echocardiogram and electrocardiogram in Doberman with dilated cardiomyopathy - case report
A cardiomiopatia dilatada (CMD) tem origem genética e afeta cães de grande porte e principalmente da raça Dobermann, nos Estados Unidos e Canadá, a prevalência dessa cardiopatia no Dobermann chega a 45% até 63%. A doença é a segunda cardiopatia com maior prevalência na espécie canina e se manifesta devido à baixa contratilidade ventricular, um defeito no miocárdio, portanto, há uma disfunção sistólica e as consequências são: menor débito cardíaco e menor bombeamento sistólico. A resposta compensatória do corpo para esse quadro é ativar o sistema renina-angiotensina-aldosterona, aumentando assim o débito cardíaco e com esse aumento, o coração se adapta dilatando suas câmaras cardíacas, no entanto, o músculo da parede cardíaca acometido por essa doença é fino e fraco, o que leva o prognóstico ser de reservado a ruim. No relato de caso, uma cadela, da raça Dobermann com 12 anos de idade apresentou o ecocardiograma sugestivo de cardiomiopatia dilatada. No exame observa-se dilatação das câmaras cardíacas esquerdas: tanto seu tamanho na diástole quanto na sístole apresenta acima dos valores de referência. O índice de volume sanguíneo tanto sistólico quanto diastólico apresenta aumento comparado aos valores de referência o que evidencia a resposta compensatória do corpo em relação ao baixo débito cardíaco da baixa contratilidade ventricular. Já no exame eletrocardiográfico foi observado um bloqueio fascicular anterior esquerdo, um distúrbio na condução intraventricular que pode estar associada a sobrecarga ventricular esquerda. Conclui-se a importância de exames cardiológicos como ecocardiograma e eletrocardiograma para diagnosticar com precisão patologias cardiológicas

Here, we quantified and assessed the nature of the relationship between hedonic hunger and BMI, in a cross-sectional study using the Portuguese version of the PFS (P-PFS) to measure hedonic hunger. Data were collected from 1266 participants belonging to non-clinical, clinical (candidates for weight-loss surgery) and population samples. Across samples, significant but weak positive associations were found between P-PFS scores and BMI, in adjusted linear regression models. However, in logistic regression models of data from the clinical and non-clinical samples, the P-PFS Food Available domain score was significantly and robustly associated with belonging to the clinical sample (OR = 1.8, 95%CI: 1.2-2.8; p = 0.008), while in the population sample it was associated to being obese (OR = 2.1, 95%CI: 1.6-2.7; p < 0.001). Thus, hedonic hunger levels are associated with obesity status with the odds of being obese approximately doubling for each unit increase in the P-PFS Food Available score.This work was supported by grants to AJO-M from BIAL Foundation (176/10), Fundação para a Ciência e Tecnologia (Junior Research and Career Development Award from the Harvard Medical Portugal Program; HMSP/ICJ/0020/2011) and the European Union’s Horizon 2020 research and innovation programme (H2020 SC1-2017-CNECT-2, project 777167), and to ST from Fundação para a Ciência e Tecnologia through the Center for Psychology at University of Porto (UID/PSI/00050/2013).
