Mullite and alumina are common in high-temperature applications because of their low thermal expansion coefficient and good thermal shock resistance. Evolution of SiC in the matrix and using it as reinforcing phase can improve thermo-mechanical properties of these materials. Also, in-situ formation of the reinforcing phases by using inorganic materials is an economical process. In this work, cr...
Fluidized bed was employed to investigate propane steam reforming over Ni-K/CeO2-Al2O3 catalyst. The catalyst was characterized by XRD, SEM, TG/DTA, and N2 adsorption-desorption tests. Effects of promoters, space velocity, temperature, and steam/propane (S/C) ratio on propane conversion, H2 yield, H2/CO ratio, and stability were studied and discussed. The experiments were carried out under cond...
Introduction: Community-acquired pneumonia (CAP) is a common type of respiratory tract infections with high morbidity and mortality. Prognostic role CRP/Albumin ratio in CAP patients still unknown. The aim this study was to investigate the CRP/albumin predicting 30-day mortality ICU requirement hospitalized CAP.
 Material Method: included CAP.Clinical records plain radiographic images were...
