Oxygen Phosphate

The HSAB principle states that hard acids (Fe surface) prefer to coordinate with hard bases (oxygen, phosphates). Hard interactions are normally ionic. Iron oxides can be readily formed and the anti wear mechanism starts to interact with the polymeric zinc metaphosphate, Zn(P03)2. 

The coordination number of Mg, Mn, and Al is 6, their preferred geometries are octahedral, and biological ligands are oxygen, phosphates, and carboxylates. Co has the coordination number of 4, tetrahedral geometries, and the biological ligands are sulfur and thiolates. The ionic radii (A) are ...

Figure 6 shows a schematic overview of the computational strategy. All quantities listed under model parameters are to be determined by the model. These parameters are combined in the vector of independent parameters p. They have to be initialized to start the calculation (see the literature for initialization strategies), and they will be varied in a systematic way in the course of the calculations. Using the initial independent parameters, the model simulates the distributions of all steady-state (temperature, salinity, oxygen, phosphate, nitrate, total inorganic carbon, alkalinity, and radiocarbon) and transient (CFCs) tracers, as in normal forward models. The simulated tracer concentrations are combined in a vector of dependent parameters p. All dependent... 

The alteration of culturing conditions can involve either the addition or deletion of innumerable macro-and micronutrients. It can also involve extremes of temperature, still versus shaken flasks, even the size and shape of the culturing vessel. There are many studies outlining the effects of chemical alteration of the media. The regulation of the production of many primary and secondary metabolites by carbon, nitrogen, oxygen, phosphate and other trace elements is well documented.
