Automatic vehicle detection and classification

This paper presents a proposal for an automatic vehicle detection and classification (AVDC) system. The proposed AVDC should classify vehicles accordingly to the Portuguese legislation (vehicle height over the first axel and number of axels), and should also support profile based classification. The AVDC should also fulfill the needs of the Portuguese motorway operator, Brisa. For the classification based on the profile we propose:he use of Eigenprofiles, a technique based on Principal Components Analysis. The system should also support multi-lane free flow for future integration in this kind of environments.

Nutritional status and overhydration: can bioimpedance spectroscopy be useful in haemodialysis patients?

Background: Protein-energy wasting (PEW), associated with inflammation and overhydration, is common in haemodialysis (HD) patients and is associated with high morbidity and mortality. Objective: Assess the relationship between nutritional status, markers of inflammation and body composition through bioimpedance spectroscopy (BIS) in HD patients. Methods: This observational, cross-sectional, single centre study, carried out in an HD centre in Forte da Casa (Portugal), involved 75 patients on an HD programme. In all participating patients, the following laboratory tests were conducted: haemoglobin, albumin, C-reactive protein (CRP) and 25-hydroxyvitamin D3 [25(OH)D3]. The body mass index of all patients was calculated and a modified version of subjective global assessment (SGA) was produced for patients on dialysis. Intracellular water (ICW) and extracellular water (ECW) were measured by BIS (Body Composition Monitor®, Fresenius Medical Care®) after the HD session. In statistical analysis, Spearman’s correlation was used for the univariate analysis and linear regression for the multivariate analysis (SPSS 14.0). A P value of <.05 was considered statistically significant. Results: PEW, inversely assessed through the ICW/body weight (BW) ratio, was positively related to age (P<.001), presence of diabetes (P=.004), BMI (P=.01) and CRP (P=.008) and negatively related to albumin (p=.006) and 25(OH)D3 (P=.007). Overhydration, assessed directly through the ECW/BW ratio, was positively related with CRP (P=.009) and SGA (P=.03), and negatively with 25(OH)D3 (P=.006) and BMI (P=.01). In multivariate analysis, PEW was associated with older age (P<.001), the presence of diabetes (P=.003), lower 25(OH)D3 (P=.008), higher CRP (P=.001) and lower albumin levels (P=.004). Over-hydration was associated with higher CRP (P=.001) and lower levels of 25(OH)D3 (P=.003). Conclusions: Taking these results into account, the ICW/BW and ECW/BW ratios, assessed with BIS, have proven to be good markers of the nutritional and inflammatory status of HD patients. BIS may be a useful tool for regularly assessing the nutritional and hydration status in these patients and may allow nutritional advice to be improved and adjusted.

Water quality issues in rivers, lakes and reservoirs in Asian countries: an approach to the problems and the methodologies

Water covers over 70% of the Earth's surface, and is vital for all known forms of life. But only 3% of the Earth's water is fresh water, and less than 0.3% of all freshwater is in rivers, lakes, reservoirs and the atmosphere. However, rivers and lakes are an important part of fresh surface water, amounting to about 89%. In this Master Thesis dissertation, the focus is on three types of water bodies – rivers, lakes and reservoirs, and their water quality issues in Asian countries. The surface water quality in a region is largely determined both by the natural processes such as climate or geographic conditions, and the anthropogenic influences such as industrial and agricultural activities or land use conversion. The quality of the water can be affected by pollutants discharge from a specific point through a sewer pipe and also by extensive drainage from agriculture/urban areas and within basin. Hence, water pollutant sources can be divided into two categories: Point source pollution and Non-point source (NPS) pollution. Seasonal variations in precipitation and surface run-off have a strong effect on river discharge and the concentration of pollutants in water bodies. For example, in the rainy season, heavy and persistent rain wash off the ground, the runoff flow increases and may contain various kinds of pollutants and, eventually, enters the water bodies. In some cases, especially in confined water bodies, the quality may be positive related with rainfall in the wet season, because this confined type of fresh water systems allows high dilution of pollutants, decreasing their possible impacts. During the dry season, the quality of water is largely related to industrialization and urbanization pollution. The aim of this study is to identify the most common water quality problems in Asian countries and to enumerate and analyze the methodologies used for assessment of water quality conditions of both rivers and confined water bodies (lakes and reservoirs). Based on the evaluation of a sample of 57 papers, dated between 2000 and 2012, it was found that over the past decade, the water quality of rivers, lakes, and reservoirs in developing countries is being degraded. Water pollution and destruction of aquatic ecosystems have caused massive damage to the functions and integrity of water resources. The most widespread NPS in Asian countries and those which have the greatest spatial impacts are urban runoff and agriculture. Locally, mine waste runoff and rice paddy are serious NPS problems. The most relevant point pollution sources are the effluents from factories, sewage treatment plant, and public or household facilities. It was found that the most used methodology was unquestionably the monitoring activity, used in 49 of analyzed studies, accounting for 86%. Sometimes, data from historical databases were used as well. It can be seen that taking samples from the water body and then carry on laboratory work (chemical analyses) is important because it can give an understanding of the water quality. 6 papers (11%) used a method that combined monitoring data and modeling. 6 papers (11%) just applied a model to estimate the quality of water. Modeling is a useful resource when there is limited budget since some models are of free download and use. In particular, several of used models come from the U.S.A, but they have their own purposes and features, meaning that a careful application of the models to other countries and a critical discussion of the results are crucial. 5 papers (9%) focus on a method combining monitoring data and statistical analysis. When there is a huge data matrix, the researchers need an efficient way of interpretation of the information which is provided by statistics. 3 papers (5%) used a method combining monitoring data, statistical analysis and modeling. These different methods are all valuable to evaluate the water quality. It was also found that the evaluation of water quality was made as well by using other types of sampling different than water itself, and they also provide useful information to understand the condition of the water body. These additional monitoring activities are: Air sampling, sediment sampling, phytoplankton sampling and aquatic animal tissues sampling. Despite considerable progress in developing and applying control regulations to point and NPS pollution, the pollution status of rivers, lakes, and reservoirs in Asian countries is not improving. In fact, this reflects the slow pace of investment in new infrastructure for pollution control and growing population pressures. Water laws or regulations and public involvement in enforcement can play a constructive and indispensable role in environmental protection. In the near future, in order to protect water from further contamination, rapid action is highly needed to control the various kinds of effluents in one region. Environmental remediation and treatment of industrial effluent and municipal wastewaters is essential. It is also important to prevent the direct input of agricultural and mine site runoff. Finally, stricter environmental regulation for water quality is required to support protection and management strategies. It would have been possible to get further information based in the 57 sample of papers. For instance, it would have been interesting to compare the level of concentrations of some pollutants in the diferente Asian countries. However the limit of three months duration for this study prevented further work to take place. In spite of this, the study objectives were achieved: the work provided an overview of the most relevant water quality problems in rivers, lakes and reservoirs in Asian countries, and also listed and analyzed the most common methodologies.

Primeiro acto: música de cena

Deste "Primeiro Acto" fazem parte algumas das músicas que fui compondo para peças de teatro ao longo de vários anos. Como é evidente, a música de cena coexiste com a imagem e representação teatral e a elas está ligada duma forma inseparável. Contudo, pretendo que algumas das músicas possam ter autonomia suficiente para se apresentarem sozinhas como peças musicais independentes. Tal foi o propósito deste disco. A escolha dos trechos de música obedeceu a um critério musical e dramático que vagamente jogasse com dois mundos: a cidade e o circo. Passados cinco anos do lançamento do CD fui convidado pela Direcção do Festival Internacional de Teatro de Expressão Ibérica – FITEI para conceber e realizar um espectáculo, para o FITEI – 2005, com músicas e canções que fui fazendo para teatro ao longo dos anos. Servindo-me como base das músicas deste CD, juntando outras, e escrevendo um guião cénico de ligação das várias músicas, com novos arranjos instrumentais, juntaram-se dez músicos, quatro cantores e quatro bailarinos para realizar esse espectáculo que, além da sua estreia em 2005 no Teatro Rivoli, no Porto, foi apresentado também nas comemorações do Dia Mundial de Teatro de 2006 no Teatro Nacional D. Maria II. Os trechos musicais escolhidos fizeram parte dos seguintes espectáculos: "Hoje começa o Circo" de João Lóio, encenado por João Mota, pelo Grupo de Teatro Roda Viva, Porto,1978; "Mais um Dia", espectáculo musical de João Lóio, Porto,1987; "Dança de Roda" de Arthur Schnitzler, encenado por João Paulo Costa, pelo Grupo de Teatro " Os Comediantes", Porto, 1990; "Um certo Plume" de Henri Michaux, encenado por Adriano Luz no Teatro da Cornucópia, Lisboa, 1993; "Aurélio da Paz dos Reis", filme realizado por Manuel Faria de Almeida, Lisboa, 1995; "Edmond" de David Mamet, encenado por Adriano Luz no Teatro Nacional D. Maria II, Lisboa, 1996; "A pandilha" de Cândido Ferreira, encenado por Cândido Ferreira, pelo Teatro Experimental do Porto, Porto, 1996 (No final deste texto dá-se informação pormenorizada sobre as peças e filme dos quais estes trechos musicais fizeram parte).Gravado em Junho, Julho e Setembro de 2000, este CD tem a seguinte ficha técnica: Direccção Musical e Produção: João Lóio; Gravação: Fernando Rangel; Mistura: Fernando Rangel e João Lóio; Masterização: Fernando Rangel; Estúdio de Gravação: Fortes & Rangel, Porto; Desenho Gráfico: José Tavares; Fotografias: Jorge Gigante e José Tavares. O “PRIMEIRO ACTO” contou com a participação dos seguintes músicos: Flauta: Jorge Salgado; Saxofone Soprano: Fernanda Alves; Saxofone Alto: Rosa Oliveira; Saxofone Tenor: Mário Santos; Isabel Anjo; Saxofone Barítono: Mário Brito; Trompa: Bohdan Sebestick; Trombone: Vítor Faria; Tuba: Manuel Costa; Harpa : Ana Paula Miranda ; Acordeão: Arnaldo Fonseca ; Guitarras: Carlos Rocha; Baixo Acústico: Firmino Neiva; Piano: Carlos Azevedo; Helena Marinho; Paulino Garcia; Violinos: David Lloyd; Richard Tomes; Suzanna Lidegran; Viola: David Lloyd; Violoncelo: Miranda T. Adams; Contrabaixo: António Augusto Aguiar; Sintetizador: João Lóio ; Percussão : Mário Teixeira; Coro: Guilhermino Monteiro, Jorge Prendas, Rui Vilhena.

Impressões de leitura: o poema do mar de Jorge Barbosa

Poema do Mar dá voz ao ideal da ―terra-longe‖ e ao ―querer bipartido‖1 do poeta caboverdiano mais desencantado frente à terra-cretcheu, amada. Jorge Barbosa (1902-1971) foi, juntamente com Baltasar Lopes e Manuel Lopes, uma das figuras de proa da Claridade. O aparecimento desta revista, em 1936, define o moderno movimento cultural caboverdiano. Conscientes da sua unidade cultural, pretendiam os ―claridosos‖ romper em definitivo com a subalternidade que os cingia à temática europeia, libertando o acto criador de tão colonial alienação. Já em 1935, ao publicar o seu primeiro livro, Arquipélago, Jorge Barbosa vencera a tradicional dependência dos modelos metropolitanos e tornava-se pioneiro da moderna poesia caboverdiana.
