The problem of insufficient regulation ability in isolated microgrid operations traditional master–slave control is targeted this research. A hybrid strategy proposed to operate multiple distributed generators (DGs) a with alleviated characteristics. Firstly, virtual synchronous generator adopted the master DG provide voltage and frequency support for system; however, lack participation slave P...

Let Z=(pq) be the integer residue ring modulo pq with odd prime numbers p and q. This paper studies the distinctness problem of modulo 2 reductions of two primitive sequences over Z=(pq), which has been studied by H.J. Chen and W.F. Qi in 2009. First, it is shown that almost every element in Z=(pq) occurs in a primitive sequence of order n > 2 over Z=(pq). Then based on this element distributio...

The mortality rate of acute paraquat (PQ) poisoning depends on the PQ concentration in the blood. It has been shown that the kidneys eliminate PQ effectively. However, early renal function deterioration is frequently observed in acute PQ intoxication. This study is designed to compare the efficacy of PQ elimination with hemoperfusion (HP) and kidneys, taking into account the functional deterior...

Primaquine (PQ), a racemic drug, is the only treatment available for radical cure of relapsing Plasmodium vivax malaria and blocking transmission of P. falciparum malaria. Recent studies have shown differential pharmacologic and toxicologic profiles of individual PQ enantiomers in rodent, dog, and primate animal models. This study was conducted in six healthy adult human volunteers to determine...

Let G ⊂ C be a bounded simply connected domain with boundary Γ and let E ⊂ G be a regular compact set with connected complement. In this paper we investigate asymptotics of the extremal constants: χn = inf p∈Pkn sup q∈Pn−kn ||pq||E ||pq||Γ , n = 1, 2, . . . , where ‖ · ‖K is the supremum norm on a compact set K, Pm is the set of all algebraic polynomials of degree at most m, and kn/n → θ ∈ [0, ...

BACKGROUND Because corneal infiltrative events (CIEs) may result from bacterial components on contact lenses, which can come from contaminated lens cases, we evaluated the biocidal efficacy of five multipurpose solutions against Gram-negative commonly isolated and CIE-associated organisms. METHODS Of the multipurpose solutions tested, one contained polyhexamethylene biguanide (PHMB)/polyquate...

The herbicide paraquat (PQ) has increasingly been reported in epidemiological studies to enhance the risk of developing Parkinson's disease (PD). Furthermore, case-control studies report that individuals with genetic variants in the dopamine transporter (DAT, SLC6A) have a higher PD risk when exposed to PQ. However, it remains a topic of debate whether PQ can enter dopamine (DA) neurons through...

Paraquat dichloride (N,N-dimethyl-4-4'-bipiridinium, PQ) is an extremely toxic chemical that is widely used in herbicides. PQ generates reactive oxygen species (ROS) and causes multiple organ failure. In particular, PQ has been reported to be an immunotoxic agrochemical compound. PQ was shown to decrease the number of macrophages in rats and suppress monocyte phagocytic activity in mice. Howeve...

The significance of detection and classification of power quality (PQ) events that disturbs the voltage and/ or current waveforms in the electrical power distribution networks is well known. Consequently, in spite of a large number of research reports in this area, the problem of PQ event classification remains to be an important engineering problem. Several feature construction, pattern recogn...
