Abstract:

Paraquat (PQ) has been demonstrated that the main target organ for the toxicity is the lung. This study aimed to investigate the potential protective effect of PDTC on the PQ-induced pulmonary damage. Fifty-four rats were divided into control, PQ-treated and PQ+PDTC-treated groups. Rats in the PQ group were administrated 40 mg/kg PQ by gastric gavage, and PDTC group with 40 mg/kg PQ followed by injection of 120 mg/kg PDTC (IP). On the days 3, 7, 14 and 21 after treatments, the activities of GSH-Px, SOD, MDA level and the content of HYP were measured. TGF-β1 mRNA and protein were assayed by RT-

Abstract In order to mitigate the volatility and randomness caused by the switching processes in a photovoltaic storage microgrid, and to enhance its stability, in this paper, the utilization of the PQ+PQ control strategy is proposed for grid-connected operation and the V/f+PQ integrated control strategy is proposed for off-grid operation. Through this approach, a smooth transition from the PQ control of the master inverter to the V/f control is achieved, enabling seamless switching between grid-connected and off-grid modes in the photovoltaic storage microgrid.

Abstract:

In the modern manufacturing mode, product is often manufactured by multi-enterprise, so effective and dynamic tracking for process quality information is the precondition to realize product quality control in distributed enterprises. Aiming at these demands, a dynamic tracking method for inter-enterprise quality information based on process quality BOM (PQ-BOM) was put forward in this paper. PQ-BOM was employed as the carrier and organization form of process quality information. With the formal definition of PQ-BOM, structure information and process information included in PQ-BOM were mapped t

Abstract:

Paraquat (PQ) is an agrochemical known to cause pulmonary fibrosis. PQ-induced collagen deposition in the lung is thought to require enzymatic formation of PQ radicals, but the specific enzymes responsible for this bioactivation event in vivo have not been identified. We tested the hypothesis that lung P450 oxidoreductase (POR or CPR) is important in PQ-induced lung fibrosis in mice. A lung-Cpr-null mouse model was utilized, which undergoes doxycycline-induced, Cre recombinase-mediated deletion of the Por gene specifically in airway Club cells and alveolar type 2 cells in the lung.

As environmental awareness increases and new energy technologies develop, microgrid systems have garnered significant attention as an important method for operating new energy sources. This trend reflects the growing emphasis on environmental protection. In the process of achieving both independent operation and grid-connected operation, the internal microgrid needs to incorporate an inverter control system equipped with various control methods. The inverter control system is responsible for regulating the inner loop parameters, and the coupling of these parameters will directly impact system

The major PQ problems are due to unbalanced and non-linear load connected at DG, unbalanced voltage variations on transmission line and unbalanced grid voltages which severely affect the performance of the system. To mitigate the above mentioned PQ problems, a novel integrated control of distribution static shunt compensator (DSTATCOM) is presented in th

Nowadays, the power quality (PQ)-related issues have become more prominent in power electronic devices. For compensating PQ disturbances various types of power devices are used. The unified power quality conditioner (UPQC) is one of the power electronic devices that is used for compensating the PQ. To reduce the PQ disturbances, the performance of series and shunt active power filters (APFs) must be improved. In this paper, an enhanced controller is proposed for improving the performance of series and shunt APFs and compensating the PQ. The enhanced technique used is the combination of artific

The sequential exposure of S. maltophilia K279a to increasing concentrations of PQ induces the formation of strains with increased resistance to PQ.
