This study investigated the action of the calcium antagonist D600 on calcium channel currents recorded in high barium solution from single, enzymatically isolated smooth muscle cells from the rabbit ear artery using the whole cell configuration of the patch-clamp technique. D600 (1-100 microM) was applied by path perfusion or by a new technique that allowed a concentration jump during the curre...

The novel field-induced single-molecule magnet based on a tetracoordinate mononuclear heteroleptic Co(II) complex involving two heterocyclic benzimidazole (bzi) and two thiocyanido ligands, [Co(bzi)2(NSC)2], (CoL4), was prepared and thoroughly characterized. The analysis of AC susceptibility data resulted in the spin reversal energy barrier U = 14.7 cm(-1), which is in good agreement with theor...

The static and dynamic magnetic properties of nanocrystalline BaFe10.4Co0.8Ti0.8O19 M -type doped barium ferrite were studied in detail to clarify the effect of interactions on the magnetic relaxation of an assembly of small particles. The logarithmic approximation was unable to account for the magnetic relaxation of the sample. Interaction effects were analyzed from the low-field susceptibilit...

There were investigated properties of WMD, especially metallographic structure, toughness and fatigue strength of welds with various oxygen amount. The connection between the properties of welds with the content of oxygen in WMD were carried out. The research results indicate that it should be limited oxygen content in steel welds. Subsequent researchers could fi nd more precisely the most bene...
