Silica refractory bricks are used especially in the metallurgical industries, due to desirable properties such as high melting point, rigidity, and high temperatures strength. In this research, different amount of SiC were added to Silica refractory containing different binders such as Borax, Boric acid, Calcium nitride, Sodium tri poly phosphate, Sodium hexa meta phosphate (SHMP) and lime. Phy...

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 ...

background patients with severe refractory cardiac angina who are not candidates for any form of invasive treatment and are already on optimal medical therapy have few therapeutic options. enhanced external counter pulsation (eecp) offers an alternative palliative and possibly therapeutic option for these patients. eecp achieves this by inducing hemodynamic effects much similar to those of the ...

the prevalence of helicobacter pylori infection and the effect of its eradication on platelet count in 95 iranian patients with chronic refractory autoimmune thrombocytopenic purpura (critp) was investigated. 69 of 95 patients were infected with h.pylori (72.6%). h.pylori eradication was obtained in 69 infected critp pa tients who were not in remission and had platelet count below 100×109 at th...

Abstract: Dolomite based refractories are widely used in Iranian steelmaking plants. In the present research, wear and corrosion of refractories used in steel-making converter lining in Esfahan Steel Company was studied. Post-mortem analysis of refractories clarified that the wear started with oxidation of carbon followed by chemical corrosion. Iron oxide from slag reacted with calcia, resu...

In recent years, the use of nanotechnology (nano-particles, nanomaterial, nano-additives and nanostructuredmaterials) has attracted attention of scholars, engineers and scientists in all scientificfields such as chemistry, medicine, material, agriculture, electronic etc. The use of nanotechnologyhas also become widespread in the refractory products (which mainly used in variou...

refractory celiac disease (rcd) is when malabsorption symptoms and villous atrophy persist despite strict adherence to a gluten free diet (gfd) for more than 12 months and other causes of villous atrophy have been ruled out.  rcd is considered a rare disease and almost exclusively occurs in adults. persistent diarrhea, abdominal pain, weight loss are the most common symptoms in rcd. also, anemi...

background: central post-stroke pain (cpsp) is a distressing pain syndrome, sometimes become refractory to the conventional pain managements. anticonvulsants have been used to alleviate different central pains. lamotrigine is a novel anticonvulsant and its proper dosage and its efficacy have not been well studied yet. the aim of this study was to evaluate the effect of 100 mg lamotrigine on ref...
