Using ultra-high-frequency (UHF) method in practical partial discharge (PD) detection can be affected by the positioning and placement of the UHF sensor. This in turn can affect the PD diagnosis. To ensure optimal performance of the sensor and understand the propagation process of electromagnetic (EM) wave, there is a need to fully analyze how the sensor??s placement affects the output signal and...
With the development of smart substations, much attention has been focused on the transient magnetic field (TMF) generated during switching operation in substations. In order to study the TMF, a portable integrated system based on Anisotropic Magneto-resistive (AMR) sensor has been developed. The system mainly consists of magnetic probe, sampling card, and industrial computer. A GPS has also been...
Full understanding of the physics underlying the striking changes—in viscoelasticity, relaxation time, and phase transitions—that mesoscopic fluid-like systems undergo when placed under confinement or when adsorbed at solid surfaces constitutes a long standing scientific challenge. One of the methods used to characterize these films consists of bringing a solid boundary closer to another solid boundary...
Aims: To clone and characterize genomic gene encoding for RMP5-mediating protein (RMP). Methods: Genomic library of lambda phage was screened with cDNA probe of full RMP encoding amino acids from 1 to 508. Southern blot analysis, Mapping of restriction enzyme sites, PCR and DNA sequencing were applied for characterization of isolated clones. Results: the RMP genomic fragments were isolated, which...
