The calcium apatite phase forming the main mineral part of bones and teeth [1], contains several ions in different amounts substituting calcium and phosphorus in the HA lattice [2, 3].
Variables such as storage method of the dried herbs, cultivation conditions for the fresh herbs that are then dried and regional factors all play into the suitability of dried herbs and the amount when substituting for fresh herbs.
Meanwhile, the party with market power attempts to put off the payment cycle as far as possible, which amounts to substituting a short capital circulation period of production and management for a long capital use period of social economic life.
In general, we find that the amount of substituted IgG is reduced for substitution therapies with higher treatment frequencies, both per treatment and also time-integrated (Figure 2B).
An appropriate amount of substituted pyrazole (20a-d).
In a prospective randomized controlled study, Knoch et al [ 54] suggested that the use of surface-heparinized ECMO circuits and membranes reduces the daily blood loss, the amount of substituted red cells and the necessary intravenous heparin dose.
The amount of CO32− substituting PO43− in the hydroxyapatite (HA) lattice of the precipitates can be varied by changing the soaking time.
X-ray diffraction (XRD), Fourier transform infrared (FTIR) and scanning electron microscope (SEM) tests show that a proper amount of fluorine substituting for oxygen in LiV3O8 can modify its structure and surface morphology.
The multi-substituted HA samples (Si-CHA) showed high solubility for silicon ion, over that of the sample containing silicon, in spite of the low substituting amount of silicon in them, 0.523 wt% for Si-CHA, as compared to 4.0 wt% for Si-HA.
The electrocarboxylation of various aromatic ketones, carried out in N-methyl-2-pyrrolidone (NMP) in a diaphragmless cell equipped with a carbon cathode and an aluminium sacrificial anode, yielded, among the products, the target hydroxy acids, the corresponding alcohols and pinacols and, quite surprisingly, detectable amounts of substituted benzoic acids and cycloexene carboxylic acids.
