convulsion is one of the most common problems in children and hypocalcemia is one the most frequent etiological items in children’s convulsion. corrected qt (qtc) in ekg is prolonged in hypocalcemia, so it can be a useful tool for evaluation of serum ionized calcium. in three groups (first seizure, multiple seizures, without seizure or control ) every 25 cases, qtc, serum ionized ca, total ca, ...

The title compound, Ca[Sn(H2PO2)6], was formed after a few days when tin(II) fluoride was allowed to react with phosphinic acid at ambient conditions. The structure consists of chains of Ca(2+) and Sn(4+) cations in octa-hedral sites with -3 symmetry bridged by bidentate hypophosphite anions. The chains are hexa-gonally close packed along [001]. The discovery of the compound and the successful ...

The ethanol (C2H5OH) vapor detection properties of a layer cubic spinel cobalt stannate as-prepared Co2SnO4 (denoted as CTOas), elaborated by low-cost spray pyrolysis method, were investigated before and after an annealing process. response layers under vapors different concentrations exhibited stable behavior in dry atmosphere at the optimum working temperatures. nanomaterials characterized tr...
