Effect Of Hydrogen Concentration On Fatigue Crack

The ambiguous relationship between fatigue crack growth rate and hydrogen concentration C H in the bulk of metal under cyclic loading of the ferrite-pearlite low-alloyed steel in hydrogen-contained environments has been found there is a certain C H value at which the crack growth resistance of steel increases. At these test conditions fracture surface demonstrates some increasing of the ...

The effect of CaCO3 and organic matter on the availability of iron and manganese was studied on sorghum Sorghum bicolor. Addition of calcium carbonate caused significant decrease in dry matter and grain yield. But yields tended to increase with the addition of organic matter at the rate of 15 tha. The iron concentration decreased with the addition of CaCO3 at all the stages of crop growth.

Our results suggest that decreased growth rate may be due to malnutrition of the iron-deficient diet, and the effect of increased energy consumption. The decreased leptin concentration and the lack of a significant correlation between leptin concentration and fat weight in the iron-deficient rats may be necessary to maintain growth.
