Depending upon customers’ demand, different agents are added such as volatiles or slag modifiers to reduce iron losses. Magnesium is injected together with CaD and/or Lime in
All three Ca2+-binding loops of photoproteins bind calcium
A calcium ion is found at each of the expected Ca 2+-binding sites, EF-hand loops I, III, and IV, in both proteins (Fig. 2A,D ), and the N termini of both proteins are disordered.The C terminus of Ca 2+-loaded apo-obelin is not observed in the electron density map and is assumed to be disordered as well.. Although Ca 2+-loaded apo-aequorin and apo-obelin share a similar overall fold, easily

Translation of Calcium in English
Calcium is a chemical element with syol Ca and atomic nuer 20. Calcium is a soft gray alkaline earth metal, fifth-most-abundant element by mass in the Earth''s crust. The ion Ca 2+ is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate. Free calcium metal is too reactive to occur in nature.

So, they synthesized the element 118 first using californium (element 98) and calcium. The Russian team wanted to use berkelium because the isotope of calcium used in the experiment, calcium-48, has 20 protons and 28 neutrons. This is the lightest stable or almost stable nucleus (the middle part of an atom) with much more neutron than proton.
