ABSTRACT
The successful development of hybrid cultivars depends on the reliability of estimated combining ability of the parent lines. The objectives of this study were to assess the combining ability of partially inbred S3 families of popcorn derived from the open-pollinated variety UENF 14, via top-crosses with four testers, and to compare the testers for their ability to discriminate the S3 progenies. The experiment was conducted in the 2015/2016 crop season, in an incomplete-block (Lattice) design with three replications. The following agronomic traits were evaluated: average plant height, grain yield (GY), popping expansion (PE), and expanded popcorn volume per hectare. The top-cross hybrid, originating from the BRS-Angela vs S3 progeny 10 combination, was indicated as promising, showing high values for specific combining ability for GY and PE. For the S3 progenies that showed high and positive GCA values for GY and PE, the continuity of the breeding program is recommended, with the advance of self-pollination generations. Fasoulas' differentiation index discriminated the BRS-Angela tester as the most suitable for identifying the superior progenies.

Este trabalho apresenta as principais características de um oxímetro de pulso atualmente em desenvolvimento pelo LEB-UFPE e NETEB-UFPB. O sistema emprega um micro-controlador como unidade central de processamento e um mostrador gráfico de cristal líquido para apresentação da curva pletismográfica e dos valores da SpO2 e da freqüência cardíaca.
This paper reports on the design and development of a microcontroller-based pulse oximeter able to display the absorption pulse, the Sp02 and the heart rate on a graphic LCD

São abordados neste trabalho alguns aspectos do processo de comunicação do homem com um equipamento específico, o computador, sob o ponto de vista dos procedimentos de anamnese. Esta comunicação dá-se através de uma interface, ou seja, um modelo que serve de interação entre o homem, neste caso específico, o médico, e o computador.
