the cell volume is shown in Fig. 2. The cell volume decreases as the Re3+ ionic radius decreases ͑from Nd3+ toYb3+͒, which is related to the lanthanide contraction reportedalso for other rare earth substitutions in the CaMnO3perovskite.11,15 In that case, substituting the Ca site with atrival[r]
Crystalline perovskite La0,67−xLi3xTiO3 with x = 0.06, 0.11 and 0.15 were prepared by solid-state-solution reactions at 1350◦C from TiO2, La2O3 and Li2CO3. Crystalline structure of these compounds was analyzed by XRD method. The ionic conducting property of La0.67−xLi3xTiO3 was characterized on Auto[r]
Influence of substitution of 3d metals for Mn on properties of La0.67Ca0.33Mn0.9 TM0.1O3 (TM = Fe, Co, Ni) compounds was studied. Ferromagnetic – paramagnetic and metals – insulator transitions were significantly affected by Mn-site substitution. However, no observable difference was found in their[r]
Oxidation process is one of the chief methods for producing free radicals in food, drugs and even living systems. Legumes are a source of not only essential nutrients required for life but also has a number of bioactive compounds required for the sustenance of good health and prevention of diseases.

Dynamic Fault Trees (DFT) are a generalization of Fault Trees which allows the evaluation of the reliability of complex and redundant systems. We propose to analyze DFT by a new version of time parallel simulation method we have recently introduced. This method takes into account the monotonicity of[r]
Bioassay guided fractionation led to the isolation of a new triterpene glycoside, holothurinogenin B (1) along with three known compounds, holothurin B (2), holothurin A (3), and holothurin A2 (4), from the methanol extract of the Vietnamese sea cucumber Holothuria scabra.
