Two important points arise here: first, that the structural approach is not in principle restricted to synchronic linguistics; second, that the study of meaning, as well as the study of phonology and grammar, can be structural in orientation.
The Principle restricted to merely possible substances follows from Leibniz's identification of substances with complete concepts.
The Strong version of the Principle restricts it to pure intrinsic properties, the Weak to pure properties.
Equivalent to the assumption of 1-consistency, or Σ01-soundness, for example, is the Reflection Principle restricted to Σ01-sentences (i.e., the sentence A in the scheme is required to be a Σ01-sentence).
It is anticipated that scaling the devices in submicron dimensions would in principle restrict the defect density and distribution variances, while at the same time, heat accumulation due to ambient temperature could accelerate the switching process.
Furthermore, pseudotetraploidy of barbels limited these studies to the use of low-resolution nuclear markers, which in principle restricts their use to study more divergent species pairs.
It should be noted that any histological approach for differentiation of M1 and M2 macrophages is in principle restricted by the fact that there are no known markers with exclusive expression on either one of these macrophage subtypes.
The direct action of laccases on lignin is, in principle, restricted to phenolic units, which only represent a small percentage of the total polymer, a fact that limits their biotechnological application.
On 21 October 1815, Stephenson had successfully tested a safety lamp of his own design, which, like Davy's, operated on the principle of restricting the flow of air being drawn into it.
Moreover, it is not clear if the harm principle justifies restricting liberty to prevent others from being harmed or only justifies restricting liberty to prevent those whose liberty is being restricted from causing harm to another.
