It is not in the nature of the subject for every connection to be proved with mathematical rigour, but, where this is lacking, experiment will frequently indicate what trust may be placed in the intuitive steps of the argument.
Although unequivocal evidence for the exact function of Nvd and Spo/Spok is lacking, experiments utilizing ecdysteroid precursors to rescue mutant phenotypes (RNAi-induced for nvd and spok) suggest that in Drosophila nvd and spo/ spok genes function in these two succeeding steps in the biochemical pathway [ 16, 26].
However, up to date, there is lack of experiment data available on the interface band alignment parameters for InN/BTO heterojunction.
Based on the drawn conclusions the procession was repeated for P/D = 1.326, where, due to lack of experiment, just the correct tendencies of the turbulence quantities and velocity field were established.
The potential cost benefit from wastewater reduction of DDR process by reducing sulfuric acid and ammonia hydroxide usage was not incorporated in the model due to the lack of experiment data on wastewater evaluation.
While shooting skills on free kicks have grown exponentially better, the basics of the wall have not changed much over the years, though it is not for a lack of experimenting.
It is suggested that some of this may result from a lack of experiments using a well defined loading regime.
We have to note that there is still a large uncertainty of photoelectric yield models because of our insufficient understandings of the nature of the small-size particle effect as well as the lack of experiments.
However, the damage-plasticity concept has been implemented in some available finiteelement method codes as temperature-dependent concrete models which are often used today in structural fire engineering, despite the lack of experiment-based calibration data.
In practice, two compensatory pathways may have a completeness less than 100%, due to either lack of experiments or biological reasons.
