Palmivorein, a new member of the elicitin family, was purified from the culture filtrate of Phytophthora palmivora isolated from the rubber tree, Hevea brasiliensis. The elicitin was obtained by ammonium sulfate precipitation and further purified using ion-exchange and gel filtration. The molecular weight, isoelectric point, amino acid composition and(More)
In this paper, an ultra-wideband bandpass filter based on slotted linear tapered-line resonator (SLTR) with embedded fold-slot feed structure for notched band is presented. The embedded fold-slot feed at the end of resonator will be comprehensively described. The proposed filter has narrow notch in the passband, resulting from the embedded fold-slot feed.(More)
This paper proposes an ultra-wideband bandpass filter based on slotted linear tapered-line resonator (SLTR) with embedded fold-slot feed structure which can create dual-notched band. The embedded fold-slot feed at both ends of resonator will be comprehensively described. The proposed filter has two notches in the passband, resulting from the embedded(More)
