A dual fluidized bed (DFB) gasification process is proposed to produce sustainable reducing gas for the direct reduction (DR) of iron ore. This novel steelmaking route compared with established DR, which based on natural gas, and emerging DR technology using electrolysis-generated hydrogen as gas. The DFB-DR found that meets requirement reactor, existing MIDREX plants, produced an energetic eff...

BLOOD VESSEL DISEASES Blood vessels have a primary function of nourishing various organs and tissues of the body by supplying them with blood. Vascular diseases are manifested clinically through three mechanisms that are reflected through the diseased vessel (s) as 1. Progressive narrowing of the lumen associated with progressive ischemia of the relevant tissues. 2. Thrombosis associated with p...

in this study, the potential of biosorbent obtained from silk maze, was investigated for the batch biosorption of direct red 81 (dr 81) in aqueous solution. the effects of temperature, biosorbent amount, contact time, initial dye concentration and ultrasonic irradiation were also evaluated. furthermore, experimental equilibrium and kinetics data were fitted by langmuir and freundlich isotherms ...

CONTEXT The vitamin D (VD) receptor (VDR) is extensively expressed in retina. The plasma concentration of 1,25-dihydroxyvitamin D3 has been inversely correlated with the severity of diabetic retinopathy (DR), which raises the possibility that VD, through its antiinflammatory, antioxidant, antiproliferative, and antiangiogenic properties, may protect diabetic retina. The TaqI VDR polymorphism ha...
