a r t i c l e i n f o Keywords: Intermediate-temperature fuel cells Cesium hydrogen phosphate Silicon pyrophosphate Proton conduction Effective medium approximation As an electrolyte for intermediate-temperature fuel cells (ITFCs), which are operative at 200 °C to 300 °C, a composite electrolyte CsH 5 (PO 4) 2 /SiP 2 O 7 has been investigated. The CsH 5 (PO 4) 2 /SiP 2 O 7 composite is reported...

A new eulytite-like orthophosphate Pb(3)Bi(PO(4))(3), was synthesized by the high temperature solution growth (HTSG) method and characterized by X-ray single crystal diffraction, powder diffraction and electron microscopy. It crystallizes in the acentric cubic space group (I4[combining macron]3d). The pure-phase powders of Pb(3)Bi(PO(4))(3), Ba(3)La(PO(4))(3) and Ba(3)Bi(PO(4))(3) were also pre...

Divalent ions of the first series transition elements and Hg were introduced into a cadmium hydroxyapatite Cd5 (P04) 30H by replacing a part of Cd2+, and the effects on the crystal growths and the structural changes were studied. Cd2+ can be exchanged with Mn2+ up to about 30 mol %, with N¡Z+or Hg2+ up to about 10 mol %, and with a little amount of Fe2+ or Cu2+. It was found that Cd5 (PO.)sOH f...

A series of oxime ether and oxime ester derivatives of the potential anti-Parkinson prodrug PD148903 (2.3) were synthesized and evaluated in pharmacological models. Oximes 4.3 (hydroxyl-oxime) and 4.4 (methoxyl-oxime) were inactive in vitro but in the Ungerstedt rat model for Parkinson’s disease 4.3 and 4.4 produced a pronounced and long lasting effect at 1.0 mg kg po. Enantiomerically pure (–)...

the radar cross section of a target plays an important role in the detection of targets by radars‎. ‎this paper presents a new method to predict the bistatic and monostatic rcs of coated electrically large objects. ‎the bodies can be covered by lossy electric and/or magnetic radar absorbing materials (rams)‎. ‎these materials can be approximated by the fresnel reflection coefficients‎. ‎the pro...

UNLABELLED The study was performed to compare the (18)F-labeled nitroimidazole compound fluoroazomycin arabinoside ((18)F-FAZA) with the standard hypoxia tracer fluoromisonidazole ((18)F-FMISO) in detection of tumor tissue hypoxia and to verify the oxygenation dependency of (18)F-FAZA uptake. METHODS Biodistribution of (18)F-FAZA was studied at various time points in EMT6 tumor-bearing BALB/c...

Recent studies have shown that anemia is commonly observed after exposure to pathogens or pathogen-derived products, which are recognized via Toll-like receptor 9 (TLR9). In the current study, we demonstrate that CpG oligodeoxynucleotide-2006, a TLR9 ligand with phosphodiester (PO; 2006-PO) but not with the phosphorothioate backbone, selectively inhibits the erythroid growth derived from human ...

This study quantified the horizontal influence range of larch stumps and coarse roots on phosphorus (P) fraction availability microsite soils explored whether this changes with different plantation types. The total P, available P fractions were measured in at 0–75 cm distances from soil depths 0–40 a pure (Larix olgensis Henry) mixed larch–ash (Fraxinus mandshurica Rupr.) plantation. Soils 85–9...
