Keeping that in mind, Holland and his team designed a new compound with two distinct properties found in nitrogenase: large shielding groups of atoms that prevented undesired reactions, and a weak iron-sulfur bond that could break easily upon the addition of electrons.
As cultured rat hepatocytes are known to die from both an iron-dependent (see above) and a weaker iron- independent pathway when the cells are incubated in cold L-15 medium [ 27, 28], we studied whether rHu-EPO prevents the iron- independent component of cold-induced cell injury.
Phase-averaged spectroscopy obtained with three of the BeppoSAX instruments shows that the 0.1 100 keV energy spectrum is described by a Comptonized component, a weak blackbody component (∼7% of the total emission) for soft X-rays, a narrow and weak iron emission line at 6.7 keV and low column density of material in the line of sight.
However, CTE showed weak scavenging activity on hydroxyl radical and a weak antioxidant iron chelator.
To be sure, there are many other moving parts in the budget – the weak iron ore and coal prices, for example, are dampening revenue – but the lower Australian dollar is working the other way.
This time, he hit a weak 4-iron that disappeared into the native shrubs and led to a double bogey.
After reaching the par-3, 206-yard No. 17 at four under par, Woods hit a weak 6-iron tee shot that faded quickly and trickled into the pond right of the green.
Having SBPs with the two mechanisms enables the bacteria to obtain iron not only from the target Fe-siderophores but also from free iron and weak iron-chelators.
As shown in Figure 5, Supporting Information Figure 6 and Table 2 the iron of AcFO or FeCit2 (weak iron-chelator) was transferred to the DFO YxeB complex, while the iron of the other ligands, Fe-Ent, Fe-EDTA, or hematin, was not.
The group's underlying earnings slumped 51% to $4.54bn down from $9.31bn a year earlier, hit by weaker iron ore, copper and aluminium prices.
