background and objectives: beta-thalassemia continues to be a cause of significant burden to the society particularly in the poorer developing countries. although sophisticated methods of screening have become available, a hunt for a cheap, rapid, objective screening method still remains elusive. thus, the objectives are to study the validity of naked-eye-single-tube-osmotic-fragility-test (nes...

When washed streptococci were incubated in a phosphate buffer containing MgSO4 and maltose (Bernheimer's basal medium) and centrifuged, no hemolytic activity was detected in the supernatant. Although incubation of the spent medium with carrier oligonucleotide did not yield active hemolysin, the mixture turned to be significantly hemolytic, upon ethanol precipitation and dehydration. Oxygen stab...

The production of highly reactive oxygen carrier particles based on low-cost iron materials is explored for chemical looping processes. Ten different Fe-based in the micronized size, both minerals and industrial residues, have been tested as precursors particles. redox reactivity each evaluated compared to state-of-the art with particulate materials, including one new material introduced this w...

Chemical-Looping Combustion (CLC) of biofuels is a promising technology for cost-efficient CO2 separation and can lead to negative emissions when combined with carbon capture storage. A potential challenge in developing CLC the effects alkali metal-containing compounds released during fuel conversion. This study investigates interactions between an oxygen carrier (OC), CaMn0.775Ti0.125Mg0.1O3-?...
