In this study, slag penetration into a magnesia refractory monolithic was investigated by the crucible test method. A synthetic calcium aluminate slag system has been used to study commercial magnesia mix refractory for 1, 2, 3, 4, 5 and 6 hours at 1450°C and 1600°C. It has been shown that the penetration rate is controlled by a diffusion mechanism at 1450°C. In this case, capillaries are the ...

The purpose of this paper is to examine the piston stress distribution using several thicknesses of the coating materials to achieve higher gasoline engine performance. First of all, finite element structure analysis is used to uncoated petrol piston made of aluminum alloy. Then, steel and cast iron piston materials are conducted and compared with the aluminum piston. After that, investigation ...

Fecoflowmetry (FFM) has been introduced to simulate natural anorectal evacuation. So far, few reports have described the effect of the herbal medicine Daikenchuto (DKT) on impaired anorectal motor function. The aim of this pilot study was to assess anorectal motor function by FFM in postoperatively impaired patients with an anorectal malformation (ARM) before and after administration of DKT. Si...

ble a disease in his hands ; viz. " Small doses of sulphate of magnesia with antimonial wine, and saline diaphoretics, usually carried off the disease, after the previous exhibition of one or two active purgatives with submuriate of mercury and scammony. A slight opiate at night was also serviceable." Indeed, I can candidly assert, that the disease abovementioned has caused me no small degree o...

In an investigation of the excretion of phosphate and other substances in short periods (chiefly of 1 hour) now being conducted in this laboratory, it has been necessary to make many inorganic phosphate determinations with limited quantities of urine. In most instances the accuracy possible with colorimetric and nephelometric methods has been sufficient, and, after a considerable amount of time...

MgAlON composites have been prepared under nitrogen atmosphere, using Dengfeng calcined alumina w(Al2O3) = 85 % and other raw material, in order to reduce the production cost and make full use of the rich bauxite resources in Henan Province. The effects of the different sintering temperature and different matrix content on the preparation and properties of MgAlON composites were investigated. T...

This article evaluates the ability of a magnesia kiln dust (PC-8) and commercial calcined MgO (MCB100), combined with ground granulated blastfurnace slag (GGBS), as constituents binary M-S-H binders. Mortars pastes were manufactured their properties compared to those Portland Cement (PC). MgO-based mortars showed an increase in setting time higher fresh consistency. At earlier ages lower mechan...
