Floods in southern Portugal: their physical and human causes, impacts and human response
Floods have been the most deadly natural disasters in Portugal during the last century,
followed by earthquakes. The type of flood known as a ‘progressive flood’ mainly affects the larger
basins, such as that of the Tagus River, and results in a large inundated area. These floods are caused
by heavy rains associated with a westerly zonal circulation that may persist for weeks. The system of
dams within the basin reduces the frequency of flooding, but cannot ‘tame’ the river. The dam system
has even contributed to an increase in the peak flow, as in the 1979 flood. Nevertheless, these floods
are not a danger for the human population. In contrast, flash floods are more dangerous and deadlier
than progressive floods, as demonstrated in 1967 and 1997. They affect the small drainage basins and
are caused by heavy and concentrated rainfall, created by convective depressions (active cold pools
or depressions caused by the interaction between polar and tropical air masses), active in the south
of the country, in the Lisbon region, Alentejo and the Algarve. Deforestation, soil impermeability,
chaotic urbanization, building on floodplains, the blockage of small creeks or their canalisation,
and the building of walls and transverse embankments along the small creeks all contribute to the
aggravation of this kind of flood.info:eu-repo/semantics/publishedVersio
Acceso a la salud de las mujeres en el contexto de la migración forzada en Portugal: vulnerabilidades y adaptación
Introduction: This article presents, the vulnerabilities related with regarding access to health services faced by refugee women. Objective: The overall goal was to gain a better understanding of the psychosocial reality of women who arrived in Portugal as a result of forced migration, focusing on the main difficulties of the migratory and adaptation journey - highlighting vulnerabilities related to health and access to health services at the present article - and the protective factors that facilitated their processes of resilience, adaptation, and social integration. Methodology: The meanings of the protagonists' experiences were disclosed through semi-structured and in-depth interviews with women´s of Iraq, Syria and Libya. Results: The investigation uncovered a number of vulnerabilities triggered by the migratory experience and gender belonging, such as prejudice, social isolation, and cultural shock (mostly linked to religion and clothing), which validated the intersectional analysis. The findings highlight a number of obstacles in the host nation, including access to health care, the quality of institutional interactions, and knowledge of the Portuguese language. Conclusions: The current investigation led to the conclusion that there are flaws in Portugal in terms of ensuring full access to health care for forced migrant women, highlighting as major obstacles: a lack of information in languages other than Portuguese, a lack of offers to learn and master the Portuguese language, a lack of knowledge about how health institutions work, and a lack of sensitivity and intercultural skills in healthcare services.Introdução: Este artigo apresenta as vulnerabilidades relacionadas no acesso aos serviços de saúde sentidas por mulheres refugiadas.

Radionuclide therapy in nuclear medicine : applying Monte Carlo simulation to investigate Bremsstrahlung imaging with a gamma camera
Radionuclide therapy is an innovative treatment in nuclear medicine that uses unsealed sources to treat some specific tumours in the human body. With an increasing interest in this modality, some efforts have been done to improve this field in nuclear medicine, such as the radiopharmaceuticals administered or the components of the imaging equipment.
Pure beta emitters are the radionuclides most used in radionuclide therapy. They are described to have extremely high potential in the treatment of malignant and non-malignant disorders. The energy of these radionuclides is absorbed close to the target site due to its low range (few mm in tissue). The problem is the impossibility of imaging their uptake in the interest places since there are no gamma rays emissions and the beta radiation is impossible to detect externally. As a result, the only radiation capable to be perceived by the gamma camera is the bremsstrahlung photons produced when an accelerate beta particle passes close to the atomic nucleus and is deflected towards it. The detection of these photons is relevant for dosimetric purposes, in order to detect the real uptake of the radionuclide and hence to know the absorbed dose in the patient.
Thus, the current dissertation reports a study about bremsstrahlung characteristics by using a Monte Carlo simulation. The study attempts to realise in what way the bremsstrahlung photons are produced in different types of biological materials, using different beta particles energies.
The simulator used was the EGSnrc (Electron Gamma Shower) system (V4 2.3.2), a package for Monte Carlo simulations. The programs were written in Mortran language and compiled to Fortran. With this study, an additional aim was to obtain a strong knowledge on EGSnrc system and to be able to modify and produce a wide range of different simulations in different physical conditions. In order to understand the bremsstrahlung photons several simulations were performed, in different media and with different energies of beta particles emissions.
Future work should be necessary in order to relate the bremsstrahlung photons understanding with the gamma camera components. The aim will be to improve the bremsstrahlung imaging and hence gathering realistic dosimetric data for the pure beta emitters.A terapia com radionuclÃdeos é um tratamento inovador em medicina nuclear, o qual utiliza fontes não seladas para tratar tumores especÃficos no corpo humano. Com o crescente interesse por esta especialidade terapêutica, alguns esforços têm sido feitos para melhorar este campo da medicine nuclear, nomeadamente através dos radiofármacos administrados ou na tecnologia dos equipamentos de imagiologia.
Os emissores beta puros (electrões) são os radionuclÃdeos mais utlizados nesta terapia. São descritos na literatura como os que apresentam um elevado potencial no tratamento de doenças malignas e benignas, uma vez que a energia destes radionuclÃdeos é absorvida perto do local alvo (poucos mm de alcance nos tecidos). O problema da utilização de beta puros reside na impossibilidade de se formar uma imagem médica, uma vez que estes radionuclÃdeos não emitem qualquer radiação gama. Como resultado, a única radiação capaz de ser detectada pela câmara gama são os fotões bremsstrahlung (radiação de travagem), produzidos quando ocorre uma desaceleração e deflexão dos electrões acelerados quando estes passam perto dos núcleos atómicos. A detecção de bremsstrahlung é muito importante para fins dosimétricos, dado que permite conhecer a verdadeira dose absorvida pelo paciente.
A presente dissertação tem como principal objectivo estudar as caracterÃsticas dos fotões bremsstrahlung, através da utilização de um simulador Monte Carlo - EGSnrc (Electron Gamma Shower). Pretende-se compreender de que forma os fotões bremsstrahlung são produzidos no interior de diferentes tipos de materiais biológicos, utilizando partÃculas beta de diferentes energias. Os códigos foram programados em linguagem Mortran e compilados para Fortran. Pretende-se também obter um forte conhecimento sobre o sistema usado, de forma a ser possÃvel produzir qualquer tipo de simulação para diferentes condições fÃsicas.
Torna-se necessário prosseguir este trabalho, a fim de se relacionar as caracterÃsticas dos fotões bremsstrahlung com os componentes da câmara gama. O objectivo será melhorar as imagens criadas por fotões bremsstrahlung e, portanto, reunir dados dosimétricos realistas para os emissores beta puros
Globalisation & Technology: educational challenges
Publicado em "Recent research developments in learning technologies", vol. 1Nowadays we are witnessing globalisation processes that converge to universal values and competencies also due to a fast and intense technologic development. Nevertheless, globalisation and technology are contradictory processes, of conflict between states, social groups and individuals in the sense that they can be agents of development but also of social exclusion. According to this, education plays a major role in the research for alternatives and in the democratisation of the Information and Communication Technologies (ICT).
Therefore, school must make an intentional effort in the sense of promoting and facilitating the access to technologic media, as technology may even permit a balanced, fair and democratic development.
Yet, the social impact of the technological improvements can only be positive with the necessary human resources, namely teachers, prepared to use them as means to foster permanent innovation in the educational process. This may correspond to the needs mentioned above, thus leading to new changes.
In this context, the use of ICT in active and strongly participated learning environments, may contribute to the education of intellectually autonomous individuals with the ability to teach them, that is, being able to determine their apprenticeship throughout their lives from the point of view of citizenship.
Particularly in telecommunications, ICT allow the creation of virtual learning and working environments where there is actual interaction and communication among every intervenient, eliminating barriers of time and space with competitive advantages to the citizen.
In this presentation we shall make a reflection about the contribution of Education and ICT to foster counter-hegemonic globalisation and to give visibility to childhood through a shared and participated relationship between all the actors of educational community.info:eu-repo/semantics/publishedVersio

Heritage Keepers: The Perils in Textile Conservation
One of the most frequent professional afflictions in Conservators-Restorers is the onset of work-related musculoskeletal disorders (WMSDs). The conservation of textiles is recognizably vulnerable to these problems. However, the assessments of the ergonomic conditions for these workers are rare or even non-existing. The present study focuses on a group of conservators-restorers of textiles and relies on the use of a Nordic Questionnaire for musculoskeletal disorders coupled with a Quick Exposure Check for the task of consolidation on a horizontal table to determine the severity and exposure levels to WMSDs. All surveyed workers reported numbness, pain or discomfort in the last 12 months for the neck region, while 67% reported the same afflictions for the back, shoulders/arms and hands/wrist. In the same time period, half of the workers used pain relievers in order to maintain their professional activity. For the textile consolidation task, the neck and back areas showed high and very high levels of exposure, respectively, and the results place these workers at a high-risk for WMSDs due to cumulative stress. Mitigation strategies are proposed but these should be paired with professional counseling. Although preliminary, this study is the first of its kind to assess the ergonomic impact of the profession in Portugal and presents a methodology that can be used to perform similar evaluations in other workplaces and/or other specialties in the Conservation and Restoration sphere, both nationally and internationall
