The defense hypothesis is commonly used to explain the adaptive role ofmetal hyperaccumulation. We tested this hypothesis using two Brassicaceae congeneric species: Alyssum pintodasilvae, a Ni hyperaccumulator, and the non-accumulator Alyssum simplex both growing on serpentine soils in Portugal. Artificial diet disks amended with powdered leaves from each plant species were used to compare the performance (mort...
This article presents an intensive analysis of a career counseling case—the case of Michael—using the Innovative Moments Coding System (IMCS) and the Return to the Problem Coding System (RPCS). Both systems are grounded in a narrative conception of the self which suggests that narrative change results from the elaboration and development of narrative exceptions to a client’s core problematic self-narrative. The...
Introdução: Acutis laxa é uma doença rara do tecido conjuntivo provocada por alterações da elastina. Caracteriza-se por pele sem elasticidade, flácida, mole e enrugada, dando aos doentes um aspecto envelhecido; o envolvimento sistémico é variável. Existem formas hereditárias e adquiridas.Relato de Caso: Lactente do sexo masculino, de seis meses de idade, no qual na sequência de internamento por bronquiolite é n...
Abstract There is a pretty wide belief that ‘soft law’ together with self-regulation provide suitable regulatory tools for emerging science and technology (S&T), possibly better tools than ‘hard law’ to cope with the need for both flexibility and adjustment to novelty and prevailing uncertainties. Soft law and self-regulation, it is argued, may also respond more adequately to increased pressure for opening up r...
Extensive Cu- and Zn-soil geochemical data in the Albernoa/Entradas–S. Domingos region (NE border of the Iberian Pyrite Belt, South Portuguese Zone) were examined to separate anomalies from background using the concentration–area fractal model. Distribution patterns of Cu and Zn concentrations in soil are primarily influenced by bedrock. The regional threshold values of Cu- and Zn-soil contents over metasedim...
Microwave irradiation was used for the first time in an efficient synthesis of benzo[a]phenoxazinium chlorides. The main advantage of this protocol is the notable reduction in reaction times and good to excellent yields of the products were achieved in comparison with classical heating conditions as described. These new series of compounds possess 5-amine and/or 2-hydroxyl substituents in the polycyclic system ...
An investigation of the use of an azaheterocycle, acridine, as an alternative photochemically removable protecting group for the carboxylic function of neurotransmitter amino acids was carried out. 9-Bromomethylacridine was used in the reaction with glycine, alanine, glutamic acid, β-alanine and γ-aminobutyric acid, to obtain model ester derivatives, which were irradiated at different wavelengths in a photochem...
Traditional polysaccharides extraction processes are often performed under heating which makes them time-, energy- and solvent-consuming. The aim of this work was to assess the possibility of using ohmic heating to replace conventional heating in the extraction of seaweed hydrocolloids. This technology is able to heat almost instantaneously the whole volume to be treated, using the ability that most materials h...
