The scientific revolution of the 17th century, which has given rise to such extraordinary progress in the understanding of nature, depended on a crucial limiting step at the start: It depended on subtracting from the physical world as an object of study everything mental – consciousness, meaning, intention or purpose.
Ultimately, however, there is a crucial limit to the subjective "field of consciousness".
The microstructure of the particle of origin for the gaseous species was observed to function as a crucial limiting factor for the migration rate.
While, PGC-1α1 activation is regulated by several mechanisms, protein stabilization is a crucial limiting step due to its short half-life under unstimulated conditions.
The vascular bundle especially in the peduncle is one of crucial limiting factors of rice yield, and it determines how plants efficiently transport photosynthetic products, mineral nutrients and water from leaf and root to panicle.
It's becoming increasingly clear, in fact, that many of the most crucial limiting factors in modern computing are no longer related to speed, cost, capacity or connectivity, but rather to us – and the all-too-human limitations of our capacities for attention, engagement and action.
But the measurements were marred by noise from cosmic rays, and astrophysicists suspected they erred on the speedy side.In papers scheduled to be published in the 17 June issue of Physics Letters B and an upcoming issue of Astronomy and Astrophysics, the LUNA researchers report that the crucial, limiting step in the CNO reaction is indeed only half as likely to occur as previously assumed.
Thus, food availability (i.e. prey abundance modified by its accessibility) is per se a crucial, limiting resource for ground-feeding insectivorous birds [30].
This is not, in our opinion, a crucial limiting factor inasmuch that this model has been historically used to model human disease and also because several features of this model have common traits with human epilepsy [42], [43].
Earlier studies on such raw materials have identified lack of nitrogen as a crucial limiting factor in fermentations.
