A series of mononuclear Mn(II), Mn(III), and Mn(IV) complexes was prepared using a single tripodal ligand (H(3)L). Addition of a cation (NH(4)(+), K(+), Na(+)) to [Mn(III)L] showed a pronounced effect on the redox potentials. Different variants of Jahn-Teller distortion, axial elongation and compression, were observed in the Mn(III) complexes.

In this work, several new examples of rare Au(III)Au(III) aurophilic contacts are reported. A series of gold(iii) double salts and complexes, viz. [AuX2(L)][AuX4] (L = 2,2'-bipyridyl, X = Cl , Br ; L = 2,2'-bipyrimidine, X = Cl , Br ; L = 2,2'-dipyridylamine, X = Cl , Br ), [AuX3(biq)] (biq = 2,2'-biquinoline, X = Cl , Br ), [LH][AuX4] (L = 2,2'-bipyridyl, X = Cl ; L = 2,2'-bipyrimidine, X = Cl...

In the present study, several pre-polymerized coagulants of iron and aluminum were tested for their efficiency towards As(V) and As(III) removal from water sources. The results showed that the pre-polymerized coagulants of iron, such as poly-ferric sulfate and poly-ferric silicate chloride, were very efficient for As(V) removal. With regard to As(III) removal, among all examined coagulants, inc...

OBJECTIVES To clarify interface pressures (IP) derived from class II and III oversize stockings. METHODS Healthy volunteers with legs fitting size S (n = 10), M (n = 6), or L (n = 6) stockings wore class II and III stockings of various sizes up to 5L. IPs were measured in the supine and the standing position with each stocking on. RESULTS In the subjects with size S legs, the IPs in the sta...

In higher plants ferredoxin (Fd):NADP(+) oxidoreductase (FNR) and Fd are each distributed in photosynthetic and non-photosynthetic organs as distinct isoproteins. We have cloned cDNAs for leaf FNR (L-FNR I and L-FNR II) and root FNR (R-FNR) from maize (Zea mays L.), and produced recombinant L-FNR I and R-FNR to study their enzymatic functions through kinetic and Fd-binding analyses. The K(m) va...

lanthanide(iii) chloro complexes of 4[n-(4’-hydroxy-3’-methoxybenzalidene) amino] antipyrine semicarbazone (hmbaaps) (i) and 4[n-(3’,4’,5’-trimethoxybenzalidene) amino] antipyrine semicarbazone (tmbaaps) (ii) with the general composition lncl3.2l (ln = la, pr, nd, sm, gd, tb, dy or ho; l = hmbaaps or tmbaaps) are reported. all the complexes were synthesized in ethanolic medium and refluxed the ...

We present photoionization modeling of galaxy populations at $z\sim0$, $2$, and $> 6$ to bridge optical far-infrared (FIR) emission-line diagrams. collect galaxies with measurements and/or FIR ([O III] 88 $\mathrm{\mu m}$ [C II] 158 m}$) emission line fluxes plot them on the [O III]$\lambda5007/\mathrm{H\beta}$--[N II]$\lambda6585/\mathrm{H\alpha}$ (BPT) L([O III]88)/SFR--L([C II]158)/SFR diagr...
