In his Third Analogy of Experience, Kant argues that a universal system of mutual causal interaction-at-a-distance is presupposed in the very construction of experience, and thereby also can be assumed to hold of objects of experience qua appearances. This implies in turn a notion of objective simultaneity. I discuss whether Kant’s project is rendered wholly obsolete by the relativity and conve...

The Newtonian notions of 3-space and time have been replaced by Minkowski space-time, a pseudo-Rimennian 4-manifold with Lorentz signature, because of the overcoming of the absolute notion of simultaneity. Even if the chrono-geometrical structure of Minkowski's space-time is xed and non-dynamical, the establishment of a metrology (rods and clocks) is necessarily observer-dependent and requires ...

The paper describes a set of seven fundamental principles for achieving “best concurrency and simultaneity.” The concurrent approach is gaining worldwide attention at this moment. The paralleling of life-cycle activities and process restructuring are being deemed necessary by more and more industries. An automobile product development process example is used in this paper to illustrate many asp...

The conventional nature of synchronisation is discussed in inertial frames, where it is found that theories using different synchronisations are experimentally equivalent to special relativ-ity. In contrary, in accelerated systems only a theory maintaining an absolute simultaneity is consistent with the natural behaviour of clocks. The principle of equivalence is discussed, and it is found that...

background: radon and its short-lived decay products are considered as the important sources of public exposure to natural radioactivity. the synergistic interaction between tobacco smoking and radon is known to be an actual problem. this study has provided a mathematical description and prognosis of the carcinogenic effects after combined action of radon with smoking. materials and methods: a ...

the aim followed in the present study was to evaluate the antioxidant activity of individual vs. combined extracts of rosemary leaves and oak fruit to detect the possible interactions in their antioxidant activity following combination and in order to find a way to use oak fruit natural antioxidants as an available massive source in iran. towards this end, methanolic extracts of rosemary and oa...

purpose: to report and review a rare variant of duane's syndrome named synergistic divergence and its surgical results. patient and findings: a 16-year-old girl presented with left face turn and reduced vision in both eyes. best corrected vision was od: 3/10 and os: 10/10. there was severe adduction deficiency of the re with simultaneous abduction of the re in left gaze. she had xt= 35 in ...
