Efeito do Lodo de Esgoto na Indução de Supressividade in vitro a Phytophthora nicotianae*

Effect of sewage sludge in vitro to suppress Phytophthora nicotianae Soil organic matter amendments may provide an alternative management practice for soil diseases caused by Phytophthora spp. In this paper we have evaluated the effectiveness of residential sewage sludge to suppress P. nicotianae under laboratory conditions. The effect of sewage sludge on P. nicotianae survival was evaluated by...

Efeito do entrelaçador na comparação de desempenho de sistemas OFDM e SCCP

This article establishes a performance comparison between the OFDM (Orthogonal Frequency Division Multiplexing) and the SCCP (Single Carrier with Cyclic Prefix) systems from the interleaver point of view. Some interleavers schemes are analyzed in a block fading channel scenario, as well as in the context of deep fade static channels. Keywords— OFDM, SCCP, interleaving, frequency selective chann...

Uso de Algoritmos Genéticos na Seleção de Atributos para Classificação de Regiões

The technological advances about remote sensing allows a better identification of urban targets in the images. The aim of this work is to classify automatically the urban spaces applying feature extraction and selection techniques, in high resolution images. To classify the road network and others urban components, some shape features that permit to recognize different objects with analogous sp...

Efeito de um cimento de ionômero de vidro sobre a remineralização de cárie na superfície oclusal – estudo in situ

This work evaluated the remineralization of demineralized enamel of pits and fissures of human third molars sealed with a glass ionomer cement (Fuji IX, GC Corporation Japan) or with a Bis-GMA sealant (Delton Dentsply). Ten volunteers participated in this in situ study that consisted of two thirty-day periods using intra-oral devices, with a week’s interval in between. Four experimental treatme...
