Calla lily (Zantedeschia aethiopica) is appreciated as cut flower and for the composition of gardens. However, many pathogens affect this species. By the traditional method of propagation, some units of new seedlings can only be produced annually. Tissue culture allows fast large-scale clonal propagation and provides healthy uniform plants. During the in vitro process, type and concentration of growth regulator could affect the growth of seedlings. Thus, the aim of this work was to determine sucrose and GA(3) concentrations to increase the efficiency of the in vitro multiplication of calla lily. After 60 days, the length of the above ground part and the roots, the number of sprouts, roots and leaves, above ground part and root fresh weight of seedlings were evaluated. The experimental design was entirely randomized with four replications. It was necessary the addition of 60.5 g L-1 sucrose associated to 5 mg L-1 GA(3) to obtain hight sprouts number. For higher length of the above ground part the addition of 45.3 g L-1 sucrose and 10 mg L-1 GA(3) was enough. Better results in the root length and number of roots were observed only in the sucrose presence, in concentrations in the range of 51.13 - 56.5 g L-1.

Purpose: Cup feeding is an alternative technique of infant feeding when the infant is not being breastfed. Healthcare providers should have experience with the cup feeding technique in order to feed safely an infant. Objectives: The aim of this study is to identify the practices and the feeding cup techniques currently being used by healthcare NICU professionals, and to explore the opinions and beliefs of health professionals regarding to feeding cup. Methods: Twelve NICU nursing assistant were interviewed. Results: Most of the professionals interviewed were able to properly execute the feeding cup technique. The main problem observed was the improper positioning of the cup while using the technique. Most of them were ‘pouring’ the milk into the infant’s mouth. Thus, the participants interviewed expressed doubts about the technique and denied having been trained for this procedure in routine work at NICU. Nevertheless, all the participants were interested to learn more about the technique. Conclusion: In general,, all the professionals interviewed were able to properly execute the feeding cup technique. The questions and concerns presented by the professionals reassure the need for research and educational activities in order to educate health professionals about the correct use of feeding cup technique to assure a safe alternative feeding for infants.

“Ressonância num copo de vidro” - Experiência (vídeo de 4 min 46 s, Graça Carraça, Departamento de Física, Escola de Ciências e Tecnologia- Universidade de Évora). A experiência sobre Ressonância num copo de vidro registada neste vídeo faz parte de um conjunto de trabalhos de divulgação, seleccionados de entre os vários disponíveis no Departamento de Física e que podem ser explorados de uma forma mais avançada nas nossas aulas. Parte deste trabalho experimental (a que não envolve luz estroboscópica) foi recentemente apresentada como actividade interactiva a um público muito jovem, crianças dos 7 aos 12 anos, do Campo de Férias SASUE - 2016, integrada no tema “Explorando o som”. A experiência suscitou muita curiosidade e o interesse sobre a explicação dos fenómenos físicos em causa, havendo um entusiasmo acrescido por terem tido a possibilidade de experimentarem eles próprios algumas partes do trabalho. Com este registo em vídeo pretende-se facilitar o trabalho de alunos e professores que queiram realizar a experiência, assim como suscitar o seu interesse para a exploração do tema.
