O “centro histórico” de Silves – limites e abordagens

Cada lugar detém características específicas, particularidades, que determinam diferentes formas de conformação dos espaços urbanos e respetivos modos de fruição. Aliados a estas condicionantes naturais, outros fatores como, a vocação, os materiais e técnicas disponíveis, local e temporalmente bem como, a ocupação territorial decorrente do processo de crescimento e vivência, vão originar a cidade, que apesar dum todo, não deixa de manter visíveis e materializadas em áreas urbanas distintas, as especificidades identitárias dos diferentes momentos da sua evolução. Na realidade, a cidade é um conjunto de testemunhos daquilo que foi sendo a sua sedimentação, facilmente reconhecidos nos diversos ―centros ou bairros históricos‖, ―baixas comerciais‖, ―zonas industriais‖, ―bairros residenciais‖, ―subúrbios massificados ou de luxo‖ e, ―interstícios rurais‖, que se articulam entre si, no quadro de dinâmicas urbanas de complexidade reconhecida

Hierarchical linear models in education sciences: an application

The importance of hierarchical structured data analysis, based on appropriate statistical models, is very well known in several research areas. In this paper we describe an application in Education Sciences: we have students grouped in classes belonging to schools, which in turn are scattered throughout the country. This grouped organization is labelled as a hierarchical or multilevel structure, and the models usually adopted for statistical analysis of this kind of data are hierarchical linear or multilevel models. The development of these models takes into account data variability within and among the hierarchical levels. We apply a hierarchical linear model (HLM) with two levels – students and schools – in order to identify relevant differences in student performance (10th grade high school in 2004/2005), considering three scientific subjects and comparing two different regions of Portugal: Coastal and Inland

Editorial for special issue “Pollutants in Acid Mine Drainage”

[Excerpt] Acid mine drainage (AMD) is among the major environmental concerns related to mining activity and often causes the complete degradation of affected ecosystems during and/or after mine closure [...]This research was funded by FCT—Fundação para a Ciência and Tecnologia through projects UIDB/04683/2020, UIDP/04683/2020, and Nano-MINENV 029259 (PTDC/CTA-AMB/29259/2017)

Spatial mobility of U and Th in a U-enriched area (Central Portugal)

Uranium and thorium are toxic in different environments. The exploitation of uranium mines and associated mine drainage leaching towards streams, sediments, and soils cause relevant pollution. The U-mine areas present high concentrations of potentially toxic elements with several consequences to ecosystems and human health. Physicochemical and potentially toxic elements of mine dumps, stream sediments, and soils from the Canto Lagar uranium mine area (Central Portugal) were analyzed. Stream sediments, soils, and mine dumps show a large range in the concentration values of Fe, U, As, Cu, Zn, Pb, and Th, suggesting geological and mine contributions. Most of the selected potential toxic elements from sediments present a low to moderate contamination degree, except for As, W, and U, which vary between high and very high contamination index. The soils must not be used in agricultural or residential activities due to contamination in As and U. This abandoned mine represents an environmental risk due to the spatial mobility and dispersion of potentially toxic elements from the dumps to the sediments and soils, as well as by surface runoff and wind.This research was funded by FCT—Fundação para a Ciência e a Tecnologia, I.P., grant number FCT FRH/BPD/64921/2009 and Nano-MINENV PTDC/CTA-AMB/29259/2017

Occurrence, properties and pollution potential of environmental minerals in acid mine drainage

This paper describes the occurrences, the mineralogical assemblages and the environmental relevance of the AMD-precipitates from the abandoned mine of Valdarcas, Northern Portugal. At this mining site, these precipitates are particularly related with the chemical speciation of iron, which is in according to the abundance of mine wastes enriched in pyrrhotite and pyrite. The more relevant supergene mineralogical assemblages include the following environmental minerals: soluble metal-salts, mainly sulphates, revealing seasonal behaviour, iron-hydroxysulphates and iron-oxyhydroxides, both forming ochre precipitates of poorly and well-crystalline minerals. Pollution potential of the most highly water soluble salts was analysed in order to evaluate the environmental effect of their dissolution by rainfall. Laboratory experiments, carried out with iron and aluminium sulphates, demonstrated the facility to release metals, sulphate and acidity upon dissolution. Regarding the ochre precipitates, composed by several less soluble iron (III)-minerals, the spatial distribution on the nearby aqueous system as well as the proportion of Jarosite, Schwertmannite and Goethite in the mixtures gave information about the halo’s contamination promoted by the AMD emerging from the waste-dump

Developmental motor profile in preschool children with primary stereotypic movement disorder

Aim. Different neuropsychological dysfunctions have been described in children with primary Stereotypic Movement Disorder (SMD), mainly attention or motor coordination problems. Up to now with no study has evaluated psychomotor functions in preschoolers primary SMD. The aim of this observational study was to gather information on the motor profiles of SMD patients in this age range in comparison with typically developing children. Patients and Methods. Twenty-six children (four girls) aged 36 to 76 months (mean= 53 ±10) with primary SMD were assessed by a structured evaluation including the Movement Assessment Battery for Children-Second Edition (MABC-2), the Beery-Buktenica Developmental test of Visual-Motor Integration (VMI), the Repetitive Behaviour Scale-Revised (RBS-R), the Motor Severity Stereotypy Scale (MSSS), and the Child Behaviour Checklist (CBCL). The diagnoses of Intellectual Disability or Autism Spectrum Disorder were exclusion criteria from the study. A comparison group of twenty-seven (four girls) typically developing children without stereotypies aged 36 to 59 months (mean= 48 ±7) was also examined. Results. The MABC-2 total score was lower than 15th percentile in fifteen children with SMD (58%); the worst performances were observed in Balance and Manual Dexterity subtests. The motor coordination score of VMI was lower than 15th percentile in ten children (38%). The majority of the children with low scores at MABC-2 also had low scores at the motor coordination subscale of VMI. MABC-2 standard scores of the clinical group were significantly lower than those of controls on MABC-2 Total, Balance, and Ball Skills subtests. Conclusion. The finding of widespread dysfunction of gross and fine motor abilities in preschoolers with primary SMD seems to delineate a peculiar phenotype and could provide new approaches to the management of this neurodevelopment disorder
