Tuberculosis (TB) is a virulent form of an infectious disease that causes global burden due to its high infectivity and fatality rate, especially the irrepressible threats latent infection. Constructing efficient strategy for prevention control TB great significance. Fortunately, we found granulomas are endowed with higher reducibility levels possibly caused by internal inflammation relatively enclosed microenvironment. Therefore, developed first targeted glutathione- (GSH-) responsive...
A grounding grid of a substation is essential for reducing the ground potential rises inside and outside during short-circuit event. The performance affected by number factors, such as soil conductivity rod corrosion. Industry always has strong desire reliable cost-effective method to monitor condition ensure personnel safety prevent equipments damage. In view increased adoption telecom sensor technologies in power industry through smart initiative, this paper proposes an online monitoring...
Context: Shikonins, a series of natural occurring naphthoquinones extracted from Arnebia euchroma (Royle) Jonst. (Boraginaceae), have antitumor activities and low toxicity. Objective: To illuminate potential activity mechanism shikonins against colorectal cancer (CRC). Materials methods: Five were isolated A. euchroma, elucidated by extensive spectroscopic analysis. Anti-proliferative (0-100 μg/mL) on human cells evaluated MTT CCK-8 for 24 or 48 h. Cell apoptosis cycle distribution examined...
We propose a neural Lyapunov approach to assessing transient stability in power electronic-interfaced microgrid interconnections. The problem of assessment is cast as one learning network-structured function the state space. Based on learned, security region estimated for monitoring interconnected microgrids real-time operation. efficacy tested and validated grid-connected three-microgrid interconnection. A comparison study suggests that proposed method can achieve less conservative...
Re-energizing an overhead distribution feeder safely is a major consideration for utility's safe work practice. One way to improve the safety determine whether still experiences short circuits before it energized. In this paper, novel fault detection technique proposed detect if de-energized system short-circuit faults. The method involves injecting thyristor-generated-controllable signal into feeder. voltage and current responses are analyzed exists. A thyristor gating control strategy...
To ensure safe re-energizing of an overhead distribution feeder after it is de-energized for extended period, a novel fault detection technique by controlling thyristor-based device proposed in companion paper. The connected parallel with breaker or recloser can inject electrical pulses adjustable strength the downstream system. method effectively detect different kinds asymmetrical faults based on unbalanced currents. However, current-based scheme not effective three-phase symmetrical...
In the three-phase four-wire system, there are usually multiple grounding points in primary neutral line due to safety and economic considerations. The rising “neutral earth voltage (NEV)” caused by a broken can threaten of nearby facilities humans; therefore, integrity conductor is vital importance for multi-grounded (MGN) system. this paper, new passive method proposed monitor MGN based on measured current data at service transformer, no need install any signal generators. Therefore, it...
Distributed Energy Resources (DERs) are more prevalent in medium-voltage distribution systems. Steady-state voltage management for these systems has become a major obstacle to power utilities due DERs' control mode typically applied, i.e., constant factor control. Voltage rises becoming norm that poses hurdles accepting many DER connections. This paper addresses this issue and provides existing mitigation strategies adopting. It also explains the imperative need develop better measures.
The capability of anti-islanding protection is a very important requirement for distributed generators (DG). A power line signaling based scheme has been proposed in companion paper. In the scheme, signal generated by electronics injected from central upstream location to DG sites. lack at site indicates that islanded. This paper summarization extensive field test proposal. Two detection algorithms have verified, impact firing angles on strength determined and effect system frequency drift...
Automatic Meter Reading (AMR) is a basic requirement of smart metering, which enables one-way or two-way communication with meters by utilizing modern technologies, such as Radio Frequency (RF), Cellular and Power Line Carrier (PLC). A PLC based AMR system uses power lines the carrier for transmitting metering data. It has been widely used in North America due to its capability accessing whole distribution network utility, making it an economical solution rural sparsely populated areas....
To ensure a safe re-energizing of an overhead distribution feeder after it is de-energized for extended period, novel fault detection technique by controlling thyristor based device proposed in this paper. The method involves injecting thyristor-generated controllable signal into the feeder. voltage and current responses are analyzed to determine if still exists. A gating control strategy algorithm also work detect all possible types faults that can happen system. Furthermore, distinguish...
