Current Opinion in Oncology, 2013 Concept of refractory coeliac disease (RCD) emerged in the past decade and refers to persistence of malnutrition and intestinal villous atrophy for more than 1 year strict gluten-free diet in coeliac patients. Diagnosis of this condition remains difficult and conditions treatment and follow-up.RCD has been subdivided into two subgroups according to the

Hittite Journal of Science and Engineering, 2019 In this study, corrosion behaviours of MgO-C refractories by incorporating different binders as phenolic resin and pyrolytic liquid obtained by waste tire pyrolysis were investigated. Moreover, the effect of porosity on the corrosion resistance of those

Effect of impurities and sintering temperature on properties of MgO-CaZrO3 ceramic [PDF]
, 2013 CaZrO3 -MgO ceramics are useful as refractories in kilns for the cement production. One method of manufacture of such ceramics is by sintering from m-ZrO2 and dolomite MgCa(CO3 )2 mixtures. In this work electrofused m-ZrO2 grains (fraction

CORROSION OF BASIC REFRACTORIES IN COPPER METALLURGY
Acta Metallurgica Slovaca, 2015 Knowledge of corrosion processes on the melt – solid boundary is very important for life time of refractories and for refractory using design. The aim of this study was to realize and evaluate laboratory corrosion tests of three types basic refractories ...

Chronic migraine: treatability, refractoriness, pseudo-refractoriness [PDF]
The Journal of Headache and Pain, 2015 Chronic migraine (CM), a highly disabling condition affecting 2-3% of the general population, represents a difficult-to-treat disorder for its unclear pathophysiology, complex comorbidities, and disappointing response to available pharmacological treatments[1]. High quality evidence (≥2 RCTs) recommends the prophylactic use of onabotulinum toxin A (155-

Current research and latest developments on refractories used as ladle linings
工程科学学报, 2019 Non-metallic inclusions significantly influence the properties of steels. Take heavy rail steel as an example, Al2O3 inclusions can become fatigue source under cyclic stress, resulting in the rupture of the steel.
