Coronary invasive angiography may or may not demonstrate fixed coronary obstruction.
They also demonstrate fixed parameter tractablity (FPT) of the problems as described in the next paragraph.
Individuals from populations experiencing different climates then demonstrate fixed differences in body sizes, even under standard laboratory conditions [ 16- 19].
All this makes it virtually impossible to demonstrate fixed patterns in the relationships between the separate contextual factors and the (adverse) outcomes of births.
The complexity and the dynamics of the obstetric care system make it virtually impossible to demonstrate fixed patterns in the relationships between the separate contextual factors and the (adverse) outcomes of births.
Yet as Hawkins demonstrates, apparently fixed identities and fortunes have their foundation on shifting sands.
Onsite experience with hollow fiber membrane systems demonstrated that fixed orientation resulted in more air scouring in the lower portion of the membranes and less at the surface.
Since the capability of the GVF-snake method to extract the signal time-frequency ridges has already been demonstrated, we fixed the frequency modulation law of the synthetic signals but studied the effect of added noise.
As a series of controversies over the past few months have demonstrated, science fixes its mistakes more slowly, more fitfully and with more difficulty than Sagan's words would suggest.
The proof-of-concept design is demonstrated by fixing conventional photocatalysts (e.g. TiO2, Pt/TiO2) inside of zeolite crystals to form a pomegranate-like structure, as confirmed by electron microscopy and FTIR spectroscopy.
Nevertheless, some of the hyperthermophilic representatives of this class, for example, the deep-sea vent archaeon Methanocaldococcus sp. FS406-22, have been demonstrated to fix nitrogen [ 22].
