When the relative element content of the food (e.g., C P) is below the threshold elemental ratio (TER, the minimum level needed for somatic maintenance) of the consumer, there will be C in relative excess, and consumer C-use efficiency and growth rate will decrease even when food is abundant [ 13].
(This reaction occurs under well-controlled temperature, pH, elemental ratio, and feed dilution with water).
The large variation of elemental ratio [I/(Sb + Bi)] would be attributed to the crystal segregations.
Bimetallic Pt Cu particles could be formed at any elemental ratio.
Polyethylene consists only of carbon and hydrogen, and the elemental ratio of C to H is 0.5.
The combination of plasma treatment with consequent thermal annealing and/or metal sputtering led to the change of surface morphology and its elemental ratio.
This enables quantitative measurements of elements and elemental ratios with μm-scale resolution, in-situ, in ferromanganese concretions.
There were no statistically significant differences between element concentrations or elemental ratios among the three different types of teeth (incisor, canine and wisdom tooth).
The following elemental ratios are routinely obtained for elements, which interfere isobarically or may affect the ionisation and/or fractionation behaviour of Hf during analysis: 176Yb/176Hf<0.0001; 176Yb/176Hf<0.0001176Yb/176Hf<0.0001
In order to classify the OFB we considered one major oxide (K2O), seven trace (Sc, Rb, Sr, Y, Zr, Nb and Ba,), six rare earth elements (REE) (La, Ce, Nd, Sm, Eu, and Yb) and seven elemental ratios (Zr/Nb, Y/Nb, Ba/Nb, Zr/Y, Sm/Nd, La/Yb and Ce/Y).
The abnormality in elemental ratios may be due to increase in Al, which disturbs the element homeostasis in serum by increasing the paramagnetic oxidant elements like Cu and Mn while decreasing Zn, an antioxidant metal required as a cofactor for CuZn SOD and Zn thionein [28].
