The genetic composition of honey bee populations from the Azores

Sequence analysis and expression of genes involved cytoskeleton and infection m...

Oomycetes from the genus Phytophthora are plant pathogens that are devastating for agriculture and natural ecosystems. The biggest productivity and yield break occurs due to the ink disease; caused by Phytophthora cinnamomi, which is one of the most widely distributed Phytophthora species, with nearly 1 000 host species. The knowledge about the molecular mechanisms responsible for its pathogenicity is an import...

Coordenação e habilidades motoras. Associação com o crescimento físico humano, ...

o objetivo da presente pesquisa foi duplo: (1) analisar as diferenças entre sexos na coordenação motora (CM) e habilidades motoras (HMs) e (2) investigar a associação de características somáticas, do envolvimento familiar e da atividade fisica na CM e HMs. A amostra foi constituída por 1632 sujeitos, 835 raparigas e 797 rapazes, 3-14 anos, que participaram no projeto de investigação intitulado 'Crescer com Saúd...

Determinants of the Intention to Purchase Organic Food Products among Portugues...

The demand for organic food products has been increasing over the last few years in Portugal and worldwide because consuming these products benefits health and the environment. Also, its production values animal welfare and promotes economic development, improving the living conditions of rural communities in low population-density territories. Thus, the general objective of this research was to identify sustai...

Contaminação da Barrinha de Esmoriz/Lagoa de Paramos por metais pesados: Efeito...

O presente trabalho centrou os seus objectivos na análise de alguns parâmetros químicos, bioquímicos, hematológicos e histológicos em tainha, Liza saliens, como medida do impacto da exposição crónica a metais pesados na Barrinha de Esmoriz/Lagoa de Paramos. Neste laguna costeira a contaminação por metais pesados é uma preocupação porque são poluentes que apresentam ao mesmo tempo persistência, capacidade de bio...

Irregular plurals: an ingenious way of teaching grammar

The main purpose of our paper is to focus on the intrinsic nature of irregular plurals in order to understand the evolution of English throughout the centuries. We intend to show how teaching and learning the irregular plurals can be not only of the utmost importance, but also good fun. By presenting creative activities, we wish to make teachers aware of these issues in the teaching of English as a foreign lang...

Kaolin spray induces changes in ABA and IAA immunodistribution in olive leaves.

The climate change scenarios predicted the accentuation of drought and high temperature events during the summer season in the Mediterranean region, coming up harmful consequences to important crops of this region, such as olive tree (Olea europaea L.). Stress conditions often stimulate changes in plants production, distribution or signal transduction of phytohormones as a response, then modifying their physiol...

Yerba mate as an inexpensive source of analytical standards of chlorogenic acid...

Chlorogenic acid isomers have been increasingly studied because of their beneficial biological effects in humans. However, their commercial analytical standards are high cost, a fact that limits research. Yerba mate (Ilex paraguariensis) is a lowcost, natural plant matrix with marked contents of chlorogenic acids, but its potential as a source of analytical standards of chlogenic acids has never been investigat...

Potencialidades e limitações da utilização de aparelhos portáteis na avaliação ...

Os equipamentos portáteis que permitem recolher informação no campo sem amostragem destrutiva são ferramentas úteis na avaliação de parâmetros diversos da performance das plantas. Permitem obter informação de forma rápida e com custos reduzidos. Podem ser também particularmente úteis em regiões onde as facilidades laboratoriais são escassas. A principal limitação será, porventura, a menor fiabilidade dos result...
