This is related to the pKa values of SMX (1.6 and 5.7), so that the antibiotic will be predominantly present as a neutral species
with pH between its pKa values.
For them it gets quite controversial, but the bearded vulture is a very charismatic and neutral species
, as it is a scavenger, and feeds on carcasses.
Now, a concept of two different atomic subsystems offers a simple solution to these puzzles if we assume that [H.sup.+](2) is a part of a subsystem H(2) that includes also a neutral species
[H.sup.0](2), dominating in intrinsic and n-type Si (which implies that the donor level of H(2) is below the midgap).
They assumed that the combustion mixture consisted of a set of neutral species
and an adiabatic flame temperature of 2200 K for a near-stoichiometric propane-air mixture at a pressure of 1 atmosphere.
This behavior is also observed for their monometallic neutral species
It is concluded that neutral species
(BzV) oxidized back to BzV+, without reacting with bCD.
Bis-p-MPPE was the preferred substrates because with bis-p-MPPE the neutral species
is the most reactive species (Behme et al., 1965).
It occurs in inorganic and organic compounds; as trivalent (III) and pentavalent (V) oxidation states; and as anionic, cationic and neutral species
. In general, the methylated and other organoarsenic compounds are less toxic than inorganic arsenic, and pentavalent arsenic is considerably less toxic than the trivalent state.
The retardation by [[H.sup.+]] may be mainly attributed to the conversion of the more reactive neutral species
of malic acid to less reactive protonated form.
Because of thermodynamic constraints, the doping process (ion ingress and egress) is associated with a transfer of neutral species
such as solvents and salts (analogous to osmosis) across the interface between the polymer and its medium of exposure.
In (C[O.sub.2] + MDEA +[H.sub.2]O) system, two neutral species
, MDEA and [H.sub.2]O, and two ionic species, [MDEAH.sup.+] and H[CO.sup.-.sub.3] in the equilibrated liquid phase, have been considered.
Saturation techniques can provide very good results in the case of neutral species
like HTO and anionic species (not with high density samples), but they are extremely time consuming for strongly sorbing cationic species or anionic species when using high dry-density samples.
