Toxocara canis, o passageiro clandestino de um voo…

A toxocarose humana é uma helmintozoonose, frequente em idade pediátrica, transmitida por ingestão de ovos presentes no solo. Crianças residentes em zonas com condições de saneamento precárias, que coabitem com animais de estimação não desparasitados e que apresentem geofagia, incorrem em eleva- do risco de desenvolvimento de toxocarose. Apresenta-se o caso de um rapaz de 5 anos, residente até há um mês em Cabo Verde, que recorreu ao serviço de urgência por febre, tosse e síndrome de dificuldade respiratória. Analiticamente destacava-se leucocitose e eosinofilia. A tomografia computorizada torácica revelava hiperdensidade irregular na base pulmonar direita. Perante serologia do Toxocara canis sugestiva de infeção aguda admitiu-se o diagnóstico de larva migrans visceral, atuando-se em conformidade terapêutica. A síndrome de larva migrans visceral atinge diversos órgãos, sendo o envolvimento pulmonar grave raro. Apesar de maioritariamente assintomática e autolimitada, quando sintomática a apresentação inespecífica e as limitações da interpretação serológica dificultam o diagnóstico e a abordagem terapêutica adequada.

Líquenes como bioindicadores de poluição atmosférica

Numa altura em que existem os mais variados equipamentos tecnológicos de avaliação da qualidade do ar recorrer a um organismo vivo para esse efeito não parece uma grande inovação a não ser que traga algum tipo de vantagem adicional, como seja permitir avaliar os efeitos da contaminação para além dos valores instantâneos obtidos por medições químicas. Os líquenes são seres vivos com características particulares, as hifas do fungo absorvem água diretamente da atmosfera, e por isso são particularmente sensíveis à poluição ambiental tornando-se um recurso a que qualquer pessoa pode recorrer para ter uma ideia da qualidade do ar que respira. Foi isso que tentámos fazer neste trabalho, identificar e comparar os líquenes de três locais, determinar a espécie a que pertencem e inferir sobre a qualidade do ar do local de onde os recolhemos, relativamente à quantidade de SO2 presente.

Promoting interculturalism through art education : a case study Portugal and Latvia

This study examines art student’s awareness, understanding and practices of intercultural art education in higher institution of art. Specifically, the research focused on Art Academy of Latvia, Riga. The purpose was to promote “interculturalism’’ among students and to acquaint them with the knowledge and skills of developing and reflecting on their cultural values and that of others’. For 10 weeks, 7 students in the Art Academy of Latvia explored the Traditional African Ceramics. My research included data gathered from student questionnaires, class discussions, interviews, observations, student artwork and photographs from their personal activities. I likewise took note of the students’ practical works and their approach to African-based ceramics. First, in literature review, I discuss my purpose of study, why the study is important, limitations, statements of problem, and further research. Secondly, I examine culture and paradigms of cultures, comprehensive context of the African history and traditions of the African ceramics, the importance of intercultural art education. Then, I describe how the case study in Latvia was carried out among 7 participants’ who are students from 2nd year – masters’ level. The case study involved 7 students from the department of graphics, glass, ceramics and painting with the aim of promoting intercultural learning among art students. The case study reveals participants’ attitude towards intercultural education and reveal the importance of intercultural education in higher institutions of art as well as other institutions of learning. Although the participants were positive attitude towards other culture, the study reveals that creating awareness through intercultural art and exposing students to other culture enhances their creativity ability to explore other culture and they are more likely to be opened in sharing their experiences and their cultural perspective. Experiencing culture based- art create awareness of other cultures

Cartografias do invisível : para uma redefinição da serigrafia como meio operativo : a dissimulação da repetição

This dissertation searches for new possibilities into the way of operating with screen printing, as well as its importance in the context of the operational methods of the visual arts, based on a personal project of painting. To this end, we resource to the mapping and the linear drawings of city maps as a way to reflect upon its use in contemporary art. Also, we establish a connection between the way these cities organize themselves and the theories of the rhizome by Gilles Deleuze and Felix Guattari; the cartography and the grids of Rosalind Krauss, with the artistic aim to build screen printing matrixes; and also the function in gesture of making ‘printings’ with the conjectures of Didi-Huberman. We investigate also the consequences of a mode of doing by resourcing to screen printing with respect to the construction of visual metaphors in painting

Event monitoring in a small and business enterprise

This paper presents an overview of the role and responsibilities of the system administrator, focusing on the need to monitor its technological infrastructure. The informatics infrastructure monitoring is, nowadays without a doubt, one of the main key points in business support. Large enterprises are no longer the only ones to feel the need to use these monitoring tools, but small and medium-sized enterprises, which also have IT environments of an increasing complexity, feel such a need. This results directly from the operation of how the business is supported on IT platforms as support for people and processes. When a system, which is vital to the organization, fails either at the hardware or software level, compromises the operating capacity and consequently the business continuity. Having this always in mind, it is extremely important to adopt monitoring systems that proactively or reactively, reduce the overall time of breaks caused by failures. A monitoring system is the way to ensure confidence in all components and the operational readiness of IT infrastructure.

Dynamic D-Vine copula model with applications to Value-at-Risk (VaR)

Regular vine copulas are multivariate dependence models constructed from pair-copulas (bivariate copulas). In this paper, we allow the dependence parameters of the pair-copulas in a D-vine decomposition to be potentially time-varying, following a nonlinear restricted ARMA(1,m) process, in order to obtain a very flexible dependence model for applications to multivariate financial return data. We investigate the dependence among the broad stock market indexes from Germany (DAX), France (CAC 40), Britain (FTSE 100), the United States (S&P 500) and Brazil (IBOVESPA) both in a crisis and in a non-crisis period. We find evidence of stronger dependence among the indexes in bear markets. Surprisingly, though, the dynamic D-vine copula indicates the occurrence of a sharp decrease in dependence between the indexes FTSE and CAC in the beginning of 2011, and also between CAC and DAX during mid-2011 and in the beginning of 2008, suggesting the absence of contagion in these cases. We also evaluate the dynamic D-vine copula with respect to Value-at-Risk (VaR) forecasting accuracy in crisis periods. The dynamic D-vine outperforms the static D-vine in terms of predictive accuracy for our real data sets.
