To cross-protect cucumber plants from Zucchini yellow mosaic virus (ZYMV), we used cold treatment to obtain an attenuated isolate of ZYMV, designated ZYMV-2002. ZYMV-2002 was obtained from a virulent ZYMV isolate after repeated low temperature treatm

Utilization of nanometer size precipitates in steel is a promising technology for the developing high tensile strength steels, and it is important to analyze the size of the precipitates. Electron microscopy is a powerful method in directly determini

A rapid analytical method of carbon in steels by glow discharge optical emission spectrometry (GD-OES) was examined. The direct-current glow discharge was found to be more effective than the radio-frequency glow discharge for the analysis of carbon i

For the determination of trace amounts of oxygen in iron and steel, a pre-treatment procedure was developed using glow discharge. This permits to remove surface oxygen contaminations, which cannot be eliminated by conventional pre-treatment methods s

Two pairs of PCR primers were designed to perform nested PCR targetting of a 540 bp fragment of the nucleocapsid (N) protein gene (N gene) of porcine epidemic diarrhea virus (PEDV). The N gene of PEDV was amplified with 4 PEDV strains and 11 small in
