NATURE OF PIG IRON.

Iron absorptive function of neonatal pig intestine.

To define the iron absorptive phase across the intestinal mucosa of neonatal pigs, the final SgFe concentration ratio of serosal to mucosal medium of everted gut sac at 1 hr incubation was measured. With .2 btg carrier iron (ferric citrate with molecular weight of 1,500) per milliliter of both the serosal and mucosal medium, the duodenum transported the iron against the concentration gradient f...

The Nature of Iron in Ferredoxin.

to detect hybrid particles. Although the RNA of dependent virus often replicated to a level about 10 per cent of that of supporting virus,' maturation of intact dependent virus within heterologous capsid was much less efficient. This could be due to a better fit between capsomeres and homologous RNA or it could be due to a spatial relationship between capsomere protein synthesis and the viral R...

environmental effects of gol-e-gohar iron ore mine on groundwater of the area

gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
