The aim of this study was to investigate the efficiency of (1) chemical precipitation by calcium oxide, (2) coagulation/flocculation by ferric chloride (FC), and (3) the combination these two methods in reducing the toxicity of wastewater generated by boat pressure washing. All three methods gave satisfactory results in the removal of colour, turbidity, Cr, Fe, Cu, Zn, and Pb. The concentration...
Polymorphism of tricalcium silicate were prepared by a calcination method with Ca(OH)2 and SiO2 as crude materials and Co2O3 as doping agent. The solid solution mechanism of Co2O3 during C3S formation were studied by means of chemical analysis, XRD and phase diagram analysis. The results show: according to phase analyse of CaO-CoO and CoO-SiO2, Co2O3 accelerated solid reaction of CaO-SiO2. When...
Sekctive coronary artedography by the Judkins' technique cao he readily accomplished in dextrocprdin. CinersdialCrspbs should be obtained in tbe mirror image obliquities for each coronary vessel and card&c cbamher. To avoid any potentid error of identitication and interpretation of the coronary vessels, films could he reviewed in revenre fashion, which would project the cardiac stnretwesasiftbe...

Materials that can capture and store CO2 are important. Though CaO is a cheap sorbent, it is inefficient for practical purposes due to sintering and poor diffusion of CO2 through the surface-CaCO3 layer. We have developed a high performance, sintering-resistant CaO-based sorbent by uniformly nanofabricating the CaO nanocrystals on SiO2 microtubes made by organogel templated polymerization.
The binary MgO–ZnO and CaO–ZnO systems the ternary CaO–MgO–ZnO system were thermodynamically optimized with phase equilibria studies in this study. Bragg-Williams random mixing model was used for solid solutions, while Modified Quasichemical Model liquid solution. thermodynamic optimization conducted using Factsage 8.1 thermochemical software. diagrams fit well experimental results. performed a...

Primitive arc magmatism and mantle wedge processes are investigated through a petrologic and geochemical study of high-Mg# (Mg/Mg ? Fe [ 0.65) basalts, basaltic andesites and andesites from the Kurile-Kamchatka subduction system. Primitive andesitic samples are from the Shisheisky Complex, a field of Quaternary-age, monogenetic cones located in the Aleutian–Kamchatka junction, north of Shiveluc...
Alkali-activated materials (AAMs) provide an opportunity to up-cycle several residues into added-value materials. Although generally praised for their performance under thermal loads, the behavior of AAMs is dictated by a multitude factors and CaO-FeOx-rich systems may differ from geopolymers. Therefore, this work ascertains high‑temperature resistance CaO‑FeOx-Al2O3-SiO2-rich AAMs. Mortars wer...
