We investigate the local existence, finite time blow-up and global existence of sign-changing solutions to inhomogeneous parabolic system with space-time forcing terms $$ u_t-\Delta u =|v|^{p}+t^\sigma w_1(x),\,\, v_t-\Delta v =|u|^{q}+t^\gamma w_2(x),\,\, (u(0,x),v(0,x))=(u_0(x),v_0(x)), where $t>0$, $x\in \mathbb{R}^N$, $N\geq 1$, $p,q>1$, $\sigma,\gamma>-1$, $\sigma,\gamma\neq0$, $w_1,w_2\no...

Rhodium(III) complexes containing 2-(2'-pyridyl)quinoline (PQ) were prepared by the reaction of RhCl3 6H2O and PQ in 1:2 mole ratio followed by addition of an excess of sodium salts to the reaction mixture. The new complexes cisRhX2(PQ)2 Y (where X = NO2 , Y = PF6 ; X = SCN or NO3 , Y = Cl; X = Y = I) and cisRh(N3)2(H2O)2(PQ) PF6 were characterized by elemental analysis, conductivity measuremen...

Electrical power quality (PQ) disturbance has become an important issue in India. On a distribution network, it is mainly caused by various nonlinear loads. Due to the varying power produced, it is affected by penetration of solar PV system as well. Therefore it is necessary detect and classify PQ events in account of evaluating a PQ problem. In other side due to increase of smart meters in sma...

The power quality (PQ) signals are traditionally analyzed in the time-domain by skilled engineers. However, PQ disturbances may not always be obvious in the original time-domain signal. Fourier analysis transforms signals into frequency domain, but has the disadvantage that time characteristics will become unobvious. Wavelet analysis, which provides both time and frequency information, can over...

We report a method for the purification of plastoquinone-9 (PQ), a prenylquinone cofactor involved in the photosynthetic electron transport chain. The described procedures relies on spinach-chloroplast isolation followed by PQ extraction and chromatographic fractionation. Extraction of PQ was achieved using partition of chloroplast suspension with methanol:petroleum ether. This procedure remove...

Paraquat (PQ) is a highly toxic herbicide, which not only leads to acute organ damage, but also to a variety of complications. Patients with severe PQ-induced poisoning may succumb to multiple organ failure involving the circulatory and respiratory systems. Although numerous studies have been performed investigating PQ poisoning, cases of extreme bradycardia caused by acute PQ-induced poisoning...

BACKGROUND Primaquine (PQ) actively clears mature Plasmodium falciparum gametocytes but in glucose-6-phosphate dehydrogenase deficient (G6PDd) individuals can cause hemolysis. We assessed the safety of low-dose PQ in combination with artemether-lumefantrine (AL) or dihydroartemisinin-piperaquine (DP) in G6PDd African males with asymptomatic P. falciparum malaria. METHODS AND FINDINGS In Burki...
