Oxidation behaviors of MgO-C refractories with different Si/SiC ratio in the 1100–1500 °C range
, 2019The oxidation behaviors of the MgO-C refractories using different Si-containing antioxidants (including Si, SiC, Si/SiC mixtures or Si/SiC-rich solid waste powders) were investigated under a controlled air flow in the range of 1100-1500 °C.

The first step in the approach to the ascites patient, after the history and physical examination, is to perform a diagnostic abdominal paracentesis for SAAG to determine whether portal hypertension is present (SAAG 1.1 g/dl or higher) or not (SAAG less than 1.1 gm/dl) (Table 1).
