1. Wide Band Stop Response Using Interdigital Capacitor/CSRR DGS in Elliptical Microstrip Low-Pass Filter
Abstract In this paper, a compact elliptic-response microstrip low pass filter (LPF) is presented with a wide stop-band using stepped impedance resonators. With high attenuation in the stop-band, the overall size reduction of the proposed filter is achieved using a novel defected ground structure technique using an interdigital capacitor and complementary sp

2. Um estudo comparativo de segmentação de imagens por aplicações do corte normalizado em grafos / A comparative study of image segmentation by application of normalized cut on graphs
O particionamento de grafos tem sido amplamente utilizado como meio de segmentação de imagens. Uma das formas de particionar grafos é por meio de uma técnica conhecida como Corte Normalizado, que analisa os autovetores da matriz laplaciana de um grafo e utiliza alguns deles para o corte. Essa dissertação propõe o uso de Corte Normalizado em grafos ori

3. Evaluation of protein and metalloprotein changes in soybean seed after genetic modification process / Avaliação das alterações proteicas e metaloproteicas em soja apos o processo de modificação genetica
This research work consisted of comparison of two kinds of soybeans [Glycine max (L.) Merrill], transgenic and non-transgenic, using proteomics and metalloproteomics changes. Firstly, soybeans proteins were extracted with an extraction buffer containing Tris-HCI (pH 8.8), KCI, DTT, PMSF and SDS, and then they were quantified by the Bradford method. In terms

4. Analysis of cut-off conditions for coaxial fibers
This paper reports the analysis of modal normalized frequency cut-off of coaxial fibers having four dielectric layers. The cut-off curves are obtained for four different structures and several modes as a function of the several parameters of the fibers (refractive index and layer dimension). The calculation is done using a transcendental equation obtained in

5. Effects of internal and external Na+ ions on inwardly rectifying K+ channels in guinea-pig ventricular cells.
1. The effects of internal and external Na+ ions on the inwardly rectifying K+ channel were studied in guinea-pig ventricular cells. 2. Single-channel currents through the inwardly rectifying K+ channel were recorded in the open cell-attached or inside-out configuration at 150 mM internal K+ and either 150 or 25 mM external K+. Internal Na+, at a concentrati
