Sentence examples for variation of iron from inspiring English sources

The vertical error bars reflect the uncertainty in the determination of x and the horizontal bars the variation of iron concentration between samples exposed in the same location.

Particle diameters between 3 and 17 nm and saturation magnetizations from 26 to 89 Am2 kg−1 were achieved by variation of iron salt concentration, reaction temperature, ratio of hydroxide ions to iron ions and ratio of Fe3+/Fe2+.

The processes that plants employ to efficiently access iron as well as genotypic variation of iron homeostasis itself are hitherto not completely understood.

Knowledge on natural variation of iron deficiency and the chlorosis response is crucial to improve growth of crops in marginal soils, where iron deficiency frequently limits growth.

In this respect, identified transcriptional differences might either represent causal genes for natural variation of iron mobilization and allocation and the associated chlorosis response in maize or be regulated by the latter.

As both genes are important for methionine salvage pathway, a prerequisite for an efficient phytosiderophore synthesis [ 6, 31- 33], they represent excellent candidates underlying natural variation of iron efficiency within the IBM population (Table  2).

Besides the variations of iron and permanent magnet reluctivities, especially the uncertainty of (upsilon_{mathrm{air}}) is crucial from the engineering viewpoint, since it allows us to simulate the variations of the air-gap thickness.

The variable source was designed to mimic variations of iron flux from the northeast slope of New Guinea to the NGCUC due to modulation of sedimentary iron resuspension as previously hypothesized.

IRP2 is more sensitive than IRP1 to variations of iron in the diet (Ref. 28), is expressed at high levels in most cell lines (Ref. 41) and, when abundantly (Ref. 42) or uniquely (Ref. 16) expressed, can act as the major or only modulator of intracellular iron metabolism, as also indicated by studies in cells in which either IRP1, IRP2 or both were knocked down (Ref. 43).

We also observed a significant flux variation of the iron line between the two observations.

Variation of the iron oxide content from 0 to 51% (C max) caused a decrease in the fluorescence intensity by a factor of 100.
