This principle of equivalence applies regardless of the cause of the claim on which the liability is based (Picard, Bermann, 2008: 260).
Social doctrine emphasizes that if the market is governed solely by the principle of equivalence in value of exchanged goods, it cannot produce the social cohesion that it requires to function well.
The debate is not settled down yet, but the dominant opinion seems to be that we have to give up at least one principle considered fundamental so far, and the unlucky one is most likely the principle of equivalence from general relativity.
Nevertheless, it has been recently proven that the use of the First Principle of Equivalence provides more accuracy in the prediction of the far field, especially in the crosspolar pattern [15].
In the context of HIV and harm reduction, this demands implementation of harm reduction services in places of detention even where they are not yet available in the community, as the principle of equivalence is insufficient to address the epidemic among prisoners (7).
it is for the national legal system of each Member State to designate the courts and tribunals having jurisdiction and to lay down the detailed procedural rules governing actions for safeguarding rights which individuals derive from EU law, provided that such rules are not less favorable than those governing similar national actions (principle of equivalence) and that they do not render practically impossible or excessively difficult the exercise of rights conferred by EU law (principle of effectiveness).
Although not followed by other researchers, as far as we know, this observation of Mounin contains some truth, because, if we follow the countless applications of the Jakobsonian theory, we see that they were carried out in strict respect to the statement of "poetic function" that "projects the principle of equivalence from the axis of selection into the axis of combination." (Jakobson 1960: 358)
As stated above, the principle of equivalence would allow arbitrarily high contaminant concentrations for short periods of time as long as the average concentration over a longer period of time was acceptable.
That is why 'the transition from Newton to Einstein centrally involves a succession of relativized constitutively a priori principles (the Newtonian Laws of Motion in the context of the Principia, in the light principle and the principle of relativity in the context of special relativity, the light principle and the principle of equivalence in the context of general relativity), and the existence of such diverse constitutively a priori principles, on my view, captures the essence of Kuhnian incommensurability' (713-14).
He developed the principle of equivalence so that he could proceed mathematically; this resulted in a curved space-time.
