Insolubilization fo Lead in Incineration Fly Ash Using Phosphate and Magnesium Solution
In order to clarify the influence of the addition rate of phosphate and magnesium to fly ash on the lead elution concentration, phosphate compounds suitable for fly ash stabilization were investigated and fly ash stabilization was performed using the suitable phosphate and Mg solution. Both of phosphoric acid and NaH2PO4 satisfied the lead landfill standard at the phosphorus addition rate of 0.25 mol / kg. However, because phosphoric acid has a very low pH, NaH2PO4 was more suitable for fly ash stabilization. In addition, stabilization using phosphate and magnesium was able to lower the phosphorus addition rate to fly ash that satisfied the lead landfill standard, as compared with stabilization with only phosphate. This means that adding magnesium to fly ash could save the amount of phosphate required to insolubilize lead. The results of the availability test showed that lead dissolution rate using phosphate and magnesium was lower than that using a chelating agent.departmental bulletin pape
Durability of Lightweight Concrete and Mortar Exposed under Some Environment
application/pdfIn this experiment, identically composed specimens of lightweight concrete and of a mortar material were exposed to a cold (coastal) environment (Monbetsu), warm sea environment (Izu) and used in the roof of a building in a warm-climate city (Yokohama) for 3years. The physical and chemical properties of the lightweight concrete specimens and those of the mortar specimens were examined. The results are as follows : (1) The lightweight concrete specimen contained more salt than the same mortar specimen. (2) The free calcium content on the surface of lightweight concrete specimens tended to decrease more than that of the mortar specimen. (3) Ettringite by sulfuric ion and Friedel’s salt by chlorine ion were not observed in either the lightweight concrete specimens or the mortar specimens.departmental bulletin pape

The Glucocorticoid Responsive Element (GRE; consensus GGTACAnnnTGTTCT), a core for a potential Glucocorticoid Responsive Unit (GRU), is given in bold. The human-specific element is underlined. The two-directional arrows indicate the predicted binding sites for regulatory factors: IRE – Insulin Responsive Element (consensus T(G/A)TTT(T/G)(G/T)); ERE – Estrogen Responsive Element (consensus GGTCAnnnTGACC); NFκB – Nuclear Factor kappa B; Sp1/2 – Specificity protein 1/2; Egr1 – Early Growth Response 1; MAZ – Myc-Associated Zinc finger protein; ZBP-89 – Zinc finger Binding Protein 148, ZNF148; HMGI/Y – High Mobility Group protein isoform I and Y, HMGA1; RORA (RORα) – Retinoic acid receptor-related Orphan Receptor α; E4BP4 – mammalian transcription factor E4 Binding Protein 4
