The multitracer method is a new tracer technique which makes it possible to trace the physical and chemical behavior of many elements simultaneously in the same environment, by using the radioactive nuclear species of various elements manufactured simultaneously. While the various studies using this technique are advancing at a rapid pace, many developments in the multitracer production method ...

tinue their race through many successive generations. Twining declared that there was no known instance in his time of a pure European descent in the country extending beyond the third remove; and Sir Joseph Fayrer's observation prolongs it to the fourth generation only, and no further. The Portuguese in Ceylon and India have, perhaps, been more fortunate. To what extent, I do not know; for the...

We study the action of metaplectic operators on Wiener amalgam spaces, giving upper bounds for their norms. As an application, we obtain new fixed-time estimates in these spaces for Schrödinger equations with general quadratic Hamiltonians and Strichartz estimates for the Schrödinger equation with potentials V (x) = ±|x|.

Geometric methods proposed by Stallings [46] for treating finitely generated subgroups of free groups were successfully used to solve a wide collection of decision problems for free groups and their subgroups [3, 19, 29, 30, 36, 41, 49]. In the present paper we employ the generalized Stallings’ methods, developed by the author in [32], to solve various algorithmic problems concerning finitely g...

This research had three basic goals: (a) to identify manipulation tactics used in close relationships; (b) to document empirically the degree of generality and specificity of tactical deployment across relationship types (mates, friends, parents); and (c) to identify links between five major personality dimensions and the usage of manipulation tactics. Twelve manipulation tactics were identifie...

It is the purpose of this short note to indicate in which way certain amalgam spaces, deened in the spirit of N. Wiener, can be used to deal with questions arising in generalized harmonic analysis in several dimensions. In some sense these results are natural extensions of corresponding one-dimensional results due to N. Wiener (e.g. Theorem 29 in his book 33i]). Amalgams are taken with respect ...

Technology transfer has become recognised as a key factor in people’s efforts to implement information technology in diverse spheres of modern life, and particularly at the workplace. However, ‘transfer’ is a unidirectional conceptualisation of the processes of technology design and implementation. It veils the work of interpretation, mediation, and reshaping involved in the processes of ‘techn...

Metric Abstract Elementary Classes (MAECs) correspond to an amalgam of the notions of Abstract Elementary Classes (AECs) and Elementary Class in the Continuous Logic. In this work, we study a proof of uniqueness (up to isomorphism) of Limit Models in MAECs [ViZa10a, Za1x], under superstability-like assumptions. Assuming this uniqueness of Limit Models, it is possible to do a preliminar study of...

We study the local-in-time regularity of the Brownian motion with respect to localized variants of modulation spaces M s and Wiener amalgam spaces W p,q s . We show that the periodic Brownian motion belongs locally in time to M s (T) and W p,q s (T) for (s − 1)q < −1, and the condition on the indices is optimal. Moreover, with the Wiener measure μ on T, we show that (M s (T), μ) and (W p,q s (T...

there is some concern that root resection may alter the seal of the previously set orthograde material. the aim of this study was to evaluate the apical sealing ability of orthograde mineral trioxide aggregate (mta) and calcium enriched mixture (cem) plugs after resection of the roots.the fluid filtration method was carried out on a total of 51 roots in three experimental (n=15) and two control...
