چکیده
Substitution of coal in coking blend with bio-coal is a potential way to reduce fossil CO2 emissions from iron and steelmaking. The current study aims explore possible means counteract negative influence cokemaking. Washing kaolin coating bio-coals were conducted remove or bind part the compounds ash that catalyzes gasification coke CO2. To further how increase reactivity related more reactive carbon catalytic oxides ash, was produced corresponding amount added for carbonization. reaction behavior coals under carbonization conditions studied thermogravimetric analyzer equipped mass spectrometer during impact addition on fluidity optical dilatometer tests blends without ash. result shows washing will lower even dilatation. containing higher components effect bio-coke reactivity, especially acetic acid when start temperature less lowered. coated 5% do not significantly dilatation-relative reference blend. bio-cokes kaolin-containing potassium oxide comparison original bio-coal. torrefied has moderate lowering temperature, which indicates originating larger impact.

Our group is interested in the intersubunit bridge region of the ribosome, which involves interactions between the 16S and 23S rRNAs. The 16S rRNA makes contacts with 23S rRNA through the A site, which is also an important site for tRNA binding and a known target site for aminoglycoside antibiotics. The 23S rRNA contacts 16S rRNA through helix 69 (H69), which also interacts with the Aand the P-...

OBJECTIVE Biological aortic valve conduits are rarely used because of the concern that possible structural valve deterioration would require complete conduit replacement in a technically demanding operation. The aim of the study was to evaluate the 10-year experience with complete aortic-root replacement using a modified composite graft in which biological valve prosthesis was located inside th...
