Synchrophasors, widely used in the monitoring and analysis of power systems, evolved from the phasor method presented by Charles Proteus Steinmetz in 1893. The phasor method is a mathematical method for solving linear sinusoidal steady-state circuits and time-varying electromagnetic fields. This paper traces the history and diffusion of the phasor method in the discipline of electrical enginee…
In this study, we investigated 78 sugarcane samples with severemosaic symptoms collected from four provinces of southern China: Guangxi, Yunnan, Hainan, and Guangdong, which cover nearly 85 % of commercial sugarcane planting zones in China. Using RT-PCR, sequencing and phylogenetic analysis, we identified 72 hybrid sugarcane samples containing causal agents of sugarcane mosaic disease. Among th…
Abstract. A novel method involving vacuum filtration deposition (VFD) of graphene suspension is developed in this study to fabricate graphene based nickel foam electrode for supercapacitor. Acid-treated graphene nanosheets in a suspension can be easily deposited in the pores of nickel foam in large quantity using this method, thus producing supercapacitors with large energy capacity. Struct…
Mitogen-activated protein kinase (MAPK) cascades are involved in plant development, stress responses and hormonal signal transduction. MAPK kinases (MAPKKs), as the key nodes in these cascades, link MAPKs and MAPKK kinases (MAPKKKs). In this study, GhMKK4, a novel group C MAPKK gene from cotton (Gossypium hirsutum), was isolated and identified. Its expression can be induced by various stresses …
