Prospecção de recursos hidrominerais e geotérmicos na Orla Ocidental Portuguesa: os casos das Termas dos Cucos e de Monte Real

A cobertura sedimentar da região Oeste portuguesa é constituída por uma série possante de sedimentos com uma variedade de fácies com idades compreendidas entre o Triásico Superior e o actual. Estes sedimentos foram depositados numa bacia alongada com direcção NNE‐SSW. A tectónica desta cobertura sedimentar é condicionada pelas falhas tardi‐Variscas que afectaram o substrato e pelo complexo evaporítico depositado na base das séries sedimentares. Séries evaporíticas espessas de idade Hetangiana formaram numerosas estruturas diapíricas. Na região Oeste de Portugal existem diversas nascentes minerais e termais usadas para hidroterapia. Esta tese tem por objectivo estudar as concessões hidrominerais das Termas dos Cucos e das Termas de Monte Real (Portugal Central), bem como as suas áreas envolventes. Estas actividades hidroterapêuticas são muito relevantes em termos sócio‐económicos para os concelhos de Torres Vedras e Leiria. Os estudos contemplados nesta tese (que incluíram trabalho de campo no domínio da geotectónica, geomorfologia e hidrogeologia) permitiram delinear modelos hidrogeológicos conceptuais, apoiados, ainda, pela re‐interpretação de estudos geofísicos e hidrogeológicos prévios. A caracterização destas áreas foi suportada por inventários hidrogeológicos, tendo sido determinante para o projecto dos furos de captação, incluindo localização e profundidade. Todos os dados compilados foram representados cartograficamente numa base de Sistemas de Informação Geográfica (SIG).

Inventário das minas de água da área do Mosteiro de Tibães: proposta preliminar de hidrogeo‐itinerários

O Mosteiro de São Martinho de Tibães localiza‐se próximo de Braga (Norte de Portugal) e foi a Casa‐mãe da Ordem Beneditina em Portugal. Este Mosteiro foi abastecido durante séculos por numerosas minas de água, a maioria das quais se encontra actualmente abandonada. Este trabalho enfatiza a importância da combinação de diferentes matérias científicas nos processos de recuperação do património mineiro abandonado, bem como de sítios geo‐arqueológicos de relevância cultural, como um exemplo do processo transformador de uma organização, no sentido de promover um segundo ciclo de vida. O objectivo deste trabalho é apresentar uma abordagem metodológica, sob o ponto de vista da geoconservação e da geodiversidade. Subsequentemente, acções específicas serão desenvolvidas para reabilitar determinadas área, com o intuito de facilitar a sua inclusão em hidrogeo‐itinerários classificados. Esta perspectiva reflecte uma importante medida para a sustentabilidade, quer para o promotor quer para o meio ambiente envolvente.

Comparison of allocation approaches in soybean biodiesel life cycle assessment

This work shows the influence of using different allocation approaches when modelling the inventory analysis in a soybean biodiesel life cycle assessment (LCA). Results obtained using mass, energy and economic based allocations are compared, focusing on the following aspects: normalised potential environmental impact (PEI) categories, total PEI and relative contributions to the total PEI from each life cycle stage and environmental impact category. Similar results are obtained either using economic and energy based allocations. However, different results are obtained when mass based allocation is used when compared with the other two. This study also illustrates that using different allocation approaches in biodiesel LCA may influence the final conclusions, especially in comparative assertions, emphasising the need to perform a sensitivity analysis in the LCA interpretation step.

Phonological and articulation treatment approaches in Portuguese children with speech and language impairments: a randomized controlled intervention study

Background: In Portugal, the routine clinical practice of speech and language therapists (SLTs) in treating children with all types of speech sound disorder (SSD) continues to be articulation therapy (AT). There is limited use of phonological therapy (PT) or phonological awareness training in Portugal. Additionally, at an international level there is a focus on collecting information on and differentiating between the effectiveness of PT and AT for children with different types of phonologically based SSD, as well as on the role of phonological awareness in remediating SSD. It is important to collect more evidence for the most effective and efficient type of intervention approach for different SSDs and for these data to be collected from diverse linguistic and cultural perspectives. Aims: To evaluate the effectiveness of a PT and AT approach for treatment of 14 Portuguese children, aged 4.0–6.7 years, with a phonologically based SSD. Methods & Procedures: The children were randomly assigned to one of the two treatment approaches (seven children in each group). All children were treated by the same SLT, blind to the aims of the study, over three blocks of a total of 25 weekly sessions of intervention. Outcome measures of phonological ability (percentage of consonants correct (PCC), percentage occurrence of different phonological processes and phonetic inventory) were taken before and after intervention. A qualitative assessment of intervention effectiveness from the perspective of the parents of participants was included. Outcomes & Results: Both treatments were effective in improving the participants’ speech, with the children receiving PT showing a more significant improvement in PCC score than those receiving the AT. Children in the PT group also showed greater generalization to untreated words than those receiving AT. Parents reported both intervention approaches to be as effective in improving their children’s speech. Conclusions & Implications: The PT (combination of expressive phonological tasks, phonological awareness, listening and discrimination activities) proved to be an effective integrated method of improving phonological SSD in children. These findings provide some evidence for Portuguese SLTs to employ PT with children with phonologically based SSD

Inventories and concentration profiles of 137Cs in undisturbed soils in the northeast of Buenos Aires Province, Argentina

Inventories and vertical distribution of (137)Cs were determined in La Plata region undisturbed soils, Argentina. A mean inventory value of 891 ± 220 Bq/m(2) was established, which is compatible with the values expected from atmospheric weapon tests fallout. The study was complemented with pH, organic carbon fraction, texture and mineralogical soil analyses. Putting together Southern Hemisphere (137)Cs inventory data, it is possible to correlate these data with the mean annual precipitations. The large differences in (137)Cs concentration profiles were attributed to soil properties, especially the clay content and the pH values. A convection-dispersion model with irreversible retention was used to fit the activity concentration profiles. The obtained effective diffusion coefficient and effective convection velocity parameters values were in the range from 0.2 cm(2)/y to 0.4 cm(2)/y and from 0.23 cm/y to 0.43 cm/y, respectively. These data are in agreement with values reported in literature. In general, with the growth of clay content in the soil, there was an increase in the transfer rate from free to bound state. Finally, the highest transfer rate from free to bound state was obtained for soil pH value equal to 8.

Síndrome de Burnout: estudo de base populacional com servidores do setor público

OBJETIVO: Identificar preditores da síndrome de Burnout em trabalhadores do setor público. MÉTODOS: Estudo transversal com amostra representativa de 879 servidores públicos municipais de uma cidade da região metropolitana de Porto Alegre, RS. Utilizou-se um questionário elaborado para a coleta de variáveis demográficas e relacionadas às características do trabalho. A percepção sobre o ambiente laboral foi analisada a partir da Work Atmosphere Scale; para avaliar a síndrome de Burnout, utilizou-se o Maslach Burnout Inventory. Foram realizadas três análises de regressão linear múltipla pelo método stepwise em que cada dimensão da síndrome foi considerada como desfecho, enquanto as demais variáveis foram estimadas como preditoras e controladas por sexo e idade. RESULTADOS: As variáveis relacionadas à percepção do ambiente de trabalho foram as que mais contribuíram para a ocorrência de burnout. A percepção do trabalho como estressante e a presença de pessoas que atrapalham o ambiente laboral participaram do modelo explicativo das três dimensões. Nove variáveis compuseram o modelo preditor, que explicou 43% da ocorrência da Exaustão Emocional. "Perceber o trabalho como estressante" apresentou maior poder explicativo. Na Despersonalização, oito variáveis compuseram o modelo em 25%; "perceber o trabalho como estressante" foi, mais uma vez, a variável de maior poder explicativo. A Baixa Realização Profissional mostrou um conjunto de variáveis com poder explicativo de 20%; ambiente de trabalho considerado bom apresentou maior peso, associando-se inversamente. CONCLUSÕES: A percepção dos servidores públicos sobre seu ambiente de trabalho tem importante papel como preditor da síndrome de Burnout. Avaliar o trabalho como estressante e presença de pessoas que atrapalham o ambiente mostraram-se como elementos de maior relevância.

Self-reported hearing performance in workers exposed to solvents

OBJECTIVE: To compare hearing performance relating to the peripheral and central auditory system between solvent-exposed and non-exposed workers. METHODS: Forty-eight workers exposed to a mixture of solvents and 48 non-exposed control subjects of matched age, gender and educational level were selected to participate in the study. The evaluation procedures included: pure-tone audiometry (500 - 8,000 Hz), to investigate the peripheral auditory system; the Random Gap Detection test, to assess the central auditory system; and the Amsterdam Inventory for Auditory Disability and Handicap, to investigate subjects' self-reported hearing performance in daily-life activities. A Student t test and analyses of covariance (ANCOVA) were computed to determine possible significant differences between solvent-exposed and non-exposed subjects for the hearing level, Random Gap Detection test and Amsterdam Inventory for Auditory Disability and Handicap. Pearson correlations among the three measures were also calculated. RESULTS: Solvent-exposed subjects exhibited significantly poorer hearing thresholds for the right ear than non-exposed subjects. Also, solvent-exposed subjects exhibited poorer results for the Random Gap Detection test and self-reported poorer listening performance than non-exposed subjects. Results of the Amsterdam Inventory for Auditory Disability and Handicap were significantly correlated with the binaural average of subject pure-tone thresholds and Random Gap Detection test performance. CONCLUSIONS: Solvent exposure is associated with poorer hearing performance in daily life activities that relate to the function of the peripheral and central auditory system.

Le monument de “Pedras da Granja” ou de “Pedras Altas” dans la “Várzea de Sintra"

In the present work, the authors describe the excavation of the monument of "Pedras da Granja" or "Pedras Altas", in the Várzea de Sintra. The first part consists of the diary of the excavations, a description of the stratigraphy encountered and of the position of the finds. An inventory of all the material found in this monument is given in the second part. The conclusions show that the monument was built on the surface of a lapiás whose crevices were used for the insertion of the standing stones, and for the deposition of the dead. Three archaeological levels were shown to exist: - upper level: Bell Beaker level; - intermediate level containing some artifacts of the Bell Beaker culture; - lower, older level with human remains more or less in situ, belonging to a local Neolithic-culture influenced by cultural imports of foreign origin. The three levels are separated, at the southern edge of the site, by layers of fallen stones. The human remains belong to some old people, but mostly to young men, women and children.

Évolution de la végétation et du climat pendant le miocène au Portugal

These work presents the quantitative and qualitative inventory and the stratigraphic distribution of fossil plants (spores, pollens, sterns, leaves and seeds) recognized the Miocene of the portuguese part of Tagus basin. For each lithostratigraphic unit, associations with ecological (paleoclimatic) meaning are defined. It was also possible to follow the evolution of the vegetation and the climate during the considered cronostratigraphic interval which includes most of the Miocene (Aquitanian to lower-middle Tortonian).

Occupational stress and coping resources in physiotherapists: a survey of physiotherapists in three general hospitals

Objectives - To identify occupational stressors and coping resources in a group of physiotherapists, and to analyse interactions between subjective levels of stress, efficacy in stress resolution and coping resources used by these professionals. Design - A sample of 55 physiotherapists working in three general hospitals in Portugal completed the Coping Resources Inventory for Stress, the Occupational Stressors Inventory and two subjective scales for stress and stress resolution. Main results - Most physiotherapists perceived that they were moderately stressed (19/55, 35%) or stressed (20/55, 36%) due to work, and reported that their efficacy in stress resolution was moderate (25/54, 46%) or efficient (23/54, 42%). Issues related to lack of professional autonomy, lack of organisation in the hierarchical command chain, lack of professional and social recognition, disorganisation in task distribution and interpersonal conflicts with superiors were identified as the main sources of stress. The most frequently used coping resources were social support, stress monitoring, physical health and structuring. Perceived efficacy in stress resolution was inversely related to perceived level of occupational stress (r = −0.61, P < 0.01). Significant correlations were found between several coping resources and the perceived level of stress and efficacy in stress resolution. Associations between problem solving, cognitive restructuring and stress monitoring and both low levels of perceived stress and high levels of perceived efficacy were particularly strong. Implications for practice - The importance of identifying stressors and coping resources related to physiotherapists’ occupational stress, and the need for the development of specific training programmes to cope with stress are supported.
