in this research, the effects of oxygen injection during the induration process were studied in order to improve the quality specifications and increase the rate of production of the iron oxide pellets. several experiments were carried out in palletizing pilot plant in different conditions of oxygen injection. the results suggested that if only the extra oxygen was injected into the furnace in ...

BACKGROUND Most portable bi-level positive airway pressure devices are not equipped with air-oxygen blenders for precisely regulating oxygen concentrations, and supplemental oxygen must be added to increase the F(IO2). Very few studies have investigated the factors that affect F(IO2), and their conclusions have been inconsistent. We investigated in vitro noninvasive ventilation (NIV) parameters...

We present here an example of an important biomedical technique in which it is critical to understand and avoid bubble nucleation in supersaturated aqueous solutions of oxygen. By doing so it is possible to inject highly supersaturated oxygen solutions through a small capillary without the formation of significant gas bubbles. The potential medical benefits of a successful technique of this kin...

Central nervous system oxygen toxicity, which occurs during diving and hyperbaric oxygen treatment, can lead to very dangerous situations, and it is of great importance to explore its mechanisms. We have speculated that cerebral blood flow plays a pivotal role in its occurrence. Except for acting as an anticonvulsant in clinical applications, acetazolamide is also a vasodilator used in both cli...

Results from several radical scavenger studies indirectly suggested an involvement of reactive oxygen species in the pathogenesis of puromycin aminonucleoside glomerulopathy. In this study, generation of reactive oxygen species was examined directly in glomeruli isolated from rats in the acute phase of puromycin aminonucleoside nephrosis and related to the changes in the glomerular antioxidant ...
